A 900 MW Power Plant Running on Biomass? It Could be a Reality in Five Years!

I thought I was never going to see the day when a large power plant would run entirely on biomass. You can understand my pessimism when you are told that a MW of powerplant will require about 8000 T of biomass every year. A 300 MW power plant will hence require an awful 2.5 million T of biomass every year. That's a heck of a lot of, well, anything. Well, there are some courageous folks around the world. Drax in the UK, for one. They are building 3x300 MW furnaces on biomass, and are arranging for a 8 million T biomass supply from around the world. (By comparison, India's total biomass based power production - outside of bagasse power - is only about 1500 MW. So the Drax project alone would be about 60% of total Indian biomass installed capacity!) While I am certainly overawed, good news, I must say. If they can operate it sustainably for a few years, biomass power would have definitely reached a milestone. Will be really keen to know how they plan to manage the supply chain. This is what the news report has to say "The vast majority of the biomass will come from North America, but there will also be locally sourced supplies of willow and elephant grass to power the furnaces. "

A Case Study of Clenergen and Yuken’s Gasification Biomass Project

Yuken India Limited, set up in 1976 under a technical and financial collaboration with Yuken Kogyo Company Limited, Japan, is a manufacturer of oil hydraulic equipment. Yuken has achieved one of the fastest growth rates in the Indian oil hydraulics industry, in the last 29 years. Clenergen India Private Limited, a wholly owned subsidiary of Clenergen Corporation, plans to enter into a minimum 15 years Power Purchase Agreement (PPA) with Yuken to supply up to 2.5MW/h, with the rest of the electricity generated being completely sold out to the National Grid System. The biomass power plants with a capacity of 4 MW/h will be installed and begin operation within 10 months upon signing of the PPA. Clenergen India plans to lease up to 800 acres of non arable land near the manufacturing site in order to grow a high yielding species of bamboo as a source of biomass for the gasification power plant. The bamboo produced is asexual, non-invasive, non-flowering plant with a lifespan of up to 50 years and above all, is a product of tissue culture. This is advancement in the sector of renewable energy, in that the cost savings created from the cultivation of biomass feedstock will allow the supply of electricity at a price lower than the current market prices and will also help to extend the industries’ vertical market penetration into these market sectors. This is certainly moving forward. With ever increasing fossil fuel prices, this is the ideal way to deal with the growing needs and the economy.   Also check out: EAI Consulting for Bio-energy & Biofuels, Bioplastics & Other Biomass-based Value Added Products

Agricultural biomass availability in India for power generation

India is primarily an agricultural nation with an extensive cultivation of different types of crops including cereal, pulses, oilseeds, fibre crops, spices and plantation crops. With the cultivation of these crops, availability of residual biomass after economic harvest makes power generation in a sustainable way. These raw materials are normally available in variable quantities depending on the acreage of cultivation, mass of residue part available. The total biomass is 511,041 kT/Yr for power generation. Among them, rice, wheat and cotton constitute a major portion with 160,000,111,000 and 21,000 kT/Yr to generate power of 5000, 3300 and 3500 MW respectively. The total power generation capacity is 17,400 MW. Besides these crops, maize, jowar, bajra, coconut, groundnut, banana, cassava and mustard are also potent generators of biomass for power to an appreciable extent. It is evident from the information stated above that the agricultural resources serve as excellent candidates for the power generation either by combustion or gasification. However it is important to note that these materials are variables by biochemical composition and moisture. So, standardization is mandatory by defining limits to make them appropriate for thermal decomposition and as consistently yielding materials of electric power. Further plans are required to efficiently collect and store for processing without time delay.

Benefits of Biomass Based Power

While we are striving hard to switch to more sustainable modes of living, there arise lots of issues questioning the efficiency of our choice of green.  Despite all the issues they might have, they have more benefits than their petroleum counterpart. After all, petroleum is not going be here forever. So, this post will focus on the benefits of biomass based power, and why is it more suited as a sustainable alternative. Let us look at the distributed generation, because biomass is available in almost all places, and especially in rural areas, and more important, as gasification based power production can be done on small scales (as low as 20 kW), this process can be used for distributed generation of power as against the centralized power production method followed today. Also, biomass based power is well suited to remote villages with no access to grid but access to significant amounts of biomass Secondly, biomass gasification based power production can be done at small scales – as small as 20 kW – unlike other sources of power (say, nuclear) that require much larger scales. This will ideally suit small villages that have only a few households. Also, this whole process could be done in rural areas, where this could open a gateway of opportunities for rural population. Given that a 1 MW biomass based power generation could require biomass growth in over 150 hectares, the opportunities for rural employment are indeed significant. Thirdly, biomass power results in no new net GHG emissions as it is part of the carbon cycle. Unlike coal and others forms of fossil fuel which have been buried millions of years ago and burning them adds to carbon in the atmosphere, responsible biomass energy generation results in no new carbon emissions or pollution. Finally, the efficiency of the biomass power generation process to make use of mostly animal and crop wastes for energy is remarkable. Also, there is a large variety of feedstock which could be used for the process. Aside from these, they also significantly reduce methane in the atmosphere, which being able to be produced economically. I suppose these are enough reasons to switch to biomass power.

Biomass based power

Biomass is a valuable physical mass of biotic factors and ideally suited for the energy generation in different forms for the fulfillment of human demands over time. Even though deep ground fuel resources of biological origin satisfy it comprehensively, the way it is oxidized today on a time scale for energy production alarms the world by a phenomenon called “Global warming”. It forces us to scan for a suitable and sustainable alternative to fossilized biomass and the answer lies with surface dwelling, active biomass which is derived either from live or dead sources for power generation. Biomass can be subjected to power generation by combustion principle which is exactly followed for fossil sources and also is found to have a greater flexibility to generate power than conventional sources. Besides combustion, biomass is readily amenable for gasification where energy as power, heat and synthetic fuels can be derived. Biomass based power proves to be highly profitable under conditions where natural resources such as wood from forests, agricultural and animal sources etc are at abundance. India is a potential hub for this alternative route of power generation but currently holds a marginal fraction of 2650 MW out of its total installed capacity of 172000 MW. It utilizes bagasse co-generation system as its major option for biomass based power production with a capacity of 1411.53 MW achieved till June, 2010. It is important to note that biomass based power is multi-dimensionally advantageous as follows Rural economic upliftment, Suited for rural areas, Ability to have small kW scale power production, Distributed generation, Carbon neutral, Efficient utilization of renewable biological sources and accession of low cost resource.

Biomass conversion to natural gas – is this being followed anywhere?

I and my team might be working on an interesting project where the company is trying to move away from natural gas for its heating purposes and into the use of biomass for the same. The reason of course has to do with economics, with natural gas prices shooting through the roof past couple of years. While we are figuring out ways in which the company could use biomass directly for heating instead of natural gas, this process poses some problems owing to the specific needs of the client. I am hence wondering if the process of converting biomass to natural gas is being followed anywhere. I know that this is pretty much feasible, but not sure about the technology maturity and economics. If there is anyone who is aware of commercial conversions of biomass to natural gas, do let me know. You can include your response in the comment section or send a note to narsi [at] eai dot in. Thank you.

Biomass Gasification for the Environment and Economy

There are a whole lot of benefits from biomass gasification, both economy wise and ecology wise. Speaking of environmental benefits, gasification plants produce significantly lower quantities of air pollutants, which is really a good thing.  The process can also reduce the environmental impact of waste disposal because it can use waste products as feedstock, generating valuable products from materials that would otherwise be disposed as wastes. Gasification's byproducts are non-hazardous and are readily marketable and also use significantly less water than traditional coal-based power generation, and can be designed so they recycle their process water, discharging none into the surrounding environment. If that is not convincing, let us look at the economical benefits. Gasification can be used to turn lower-priced feedstocks into valuable products like electricity, substitute natural gas, fuels, chemicals, and fertilizers. For example, a chemical plant can gasify petcoke or high sulfur coal instead of using high-priced natural gas, thereby reducing its operating costs. While a gasification power plant is capital intensive (like any very large manufacturing plant), its operating costs are potentially lower than conventional processes or coal-fired plants because gasification plants are more efficient and require less back-end pollution control equipment. With continued research and development efforts and commercial operating experience, the cost of these units will continue to decrease. The process also offers wide fuel flexibility. A gasification plant can vary the mix of solid feedstocks, or run on gas or liquid feedstocks—giving it more freedom to adjust to the price and availability of its feedstocks. Many predict that coal-based power plants and other manufacturing facilities will be required to capture and store CO2, or participate in a carbon cap and trade market. In this scenario, gasification projects will have a cost advantage over conventional technologies.

Biomass Gasification in India to Generate Lakhs of Jobs

Emerging green economy in the country may see creation of nine lakh jobs in India by 2025, a top government official said.

"India could generate nine lakh jobs by 2025 in biomass gasification, of which three lakh would be in manufacturing of stoves and six lakh in areas such as processing into briquettes and pellets and the fuel supply chain," Ministry of Micro, Small and Medium Enterprises (MSME) Secretary Dinesh Rai said.

More from here.

I am not sure if biomass gasification alone could generate almost a million jobs. The secretary appears to have his numbers done for him all right, but I still wonder.

It will of course be good if it comes true. It was only yesterday that I met this gentleman whose company manufactures efficient burners for kerosene stoves and he was quite hopeful about the micro-gasifiers as well.

Let's see how it goes

Biomass Gasification Power Production – Bottlenecks and Barriers

Biomass gasification is a process where materials are transformed by thermal decomposition under partially oxygenated conditions to generate syn-gas for power generation. It seems to be a powerful technique where energy can be produced in a sustainable way along with valuable products such as green oil and biochar but it is multi step process where bottlenecks continuously arises at every step of the production pathway. The most commonly encountered limitations are batch to batch variation in  energy content, purification of the syngas, contaminants influence in the performance of the engines, ash and biochar disposals, toxic gas emissions and operational efficiency of the gas engines and mandatory modifications required to make the engines energy effective. In addition to these prime technical problems, others notable hindrances are insufficient capacity of the stakeholders and inadequate institutional and policy framework at the national, regional and local levels and limited access to financing and lack of interest on part of the state electricity boards (SEBs) in promoting biomass power generation etc. In India, conditions are further complicate by lack of working capital, limited interest in power projects, lack of effective regulatory framework and absence of effective information dissemination etc. In spite of the limitations, the technology continues to gain acceptance. Its potential to meet the energy demands on a flexible scale makes a robust move to outweigh the magnitude of limitations associated with it.

Cons of Gasifiers

The use of biomass gasification for power production is not new, but its use has been so far been limited and its contribution to the overall power production has so far been negligible in India. The producer gas derived from biomass gasification can be used for either producing power (by use in a gas engine) or can be used for thermal applications. With better technologies evolving for both gasifiers and gas engines, it can be expected that biomass gasification could start contributing a lot more to the overall power production in India. For starters, biomass gasifiers are reactors that heat biomass in a low-oxygen environment to produce a fuel gas called the producer gas. The gas produced from a gasifier can drive highly efficient devices such as gensets, turbines and fuel cells to generate electricity. A biomass gasification system consists primarily of a reactor or container into which fuel is fed along with a limited (less than stoichiometric, that required for complete combustion) supply of air. Heat for gasification is generated through partial combustion of the feed material. The resulting chemical breakdown of the fuel and internal reactions result in a combustible gas usually called producer gas. Though gasifiers are really special in their own way, they have their limitations. Gasification is a complex and sensitive process. There exists high level of disagreement about gasification among engineers, researchers, and manufacturers. Several manufacturers claim that their unit can be operated on all kinds of biomass. But it is a questionable fact as physical and chemical properties varies fuel to fuel. Gasifiers require atleast half an hour or more to start the process. Raw material is bulky and frequent refuelling is often required for continuous running of the system. Handling residues such as ash, tarry condensates is time consuming and dirty work. Driving with producer gas fueled vehicles requires much more and frequent attention than gasoline or diesel fueled vehlicles. Getting the producer gas is not difficult, but obtaining in the proper state is the challenging task. The physical and chemical properties of producer gas such as energy content, gas composition and impurities vary time to time. All the gasifiers have fairly strict requirements for fuel size, moisture and ash content. Inadequate fuel preparation is an important cause of technical problems with gasifiers. Gasifier is too often thought of as simple device that can generate a combustible gas from any biomass fuel. A hundred years of research has clearly shown that key to successful gasification is gasifier specifically designed for a particular type of fuel. Hence, biomass gasification technology requires hard work and tolerance. As I said, gasifiers are indeed special in their own way. I’d rather we just wait for the technology to advance in the future to go far beyond its limitations. After all, as I said then and I will again, petroleum is not here forever, and we need more sustainable feedstock and advanced technologies for processing.

Cool Solutions for Your Hot Problems – Getting Your Heating Costs Under Control

industrial heating boiler 1 Sustainable Industrial & Commercial Heating Solutions - A Critical Pain Point No, this blog post is not about those hot problems. It is about problems companies, especially in the manufacturing sector, face for their heating requirements! With the prices of furnace oil, diesel and LPG increasing alarmingly in the past few years, companies suddenly find their costs of their energy shooting up to unaffordable levels. Suddenly, using renewable and sustainable energy sources such as solar and biomass, and utilizing heat that was wasted earlier appear to be the way forward. I hence thought I’d provide an overview of renewable and sustainable options available for heating requirements in factories. The following are the sustainable heating avenues that are technically feasible today:

  • Solar Water Heater
  • Biomass
  • Waste Heat Recovery/CHP/Cogen
  • CST (concentrating solar thermal)
  • Energy efficiency heating equipment
  • Back pressure steam turbine
Solar Water Heaters Yes, we are talking about the simple and common solar water heaters. Could they provide a solution for industrial heating needs? The answer is Yes. Solar water heaters typically can provide temperatures up to only about 70OC, while many industries such as food and diary will require temperatures upwards of 150 deg C. This should however not be a deterrent as solar water heating can be used to preheat the water.  To the extent that solar water heaters can be used to replace furnace oil or diesel, proportionate cost savings can be derived. Taking the current prices of furnace oil, diesel, LPG or natural gas, even partial substitution of any of these fuels with solar heat makes significant economic sense. The capital cost involved in setting up this solar water heater facility can be recovered in about 2.5 years at the current prices of fossil fuels. Biomass based heating Let's consider a factory currently using about 10000 m3 of natural gas per day (or about 10,000 liters of furnace oil per day) for this discussion. Such a factory can save considerably by switching over to biomass from fossil fuels for its heating applications. The advantage with biomass based heating is that it is a firm source of energy and can technically replace the entire fossil fuel use for 24X7 operations. Biomass–based heating is a fairly old idea, but today, this can provide more bang for the buck using the gasifier technology which is a much more efficient way to provide heating than direct combustion. Essentially, combustion is not the best way to derive heat energy from biomass. Gasification, by first converting the biomass into an organic gas called the producer gas, makes the entire heating process far more efficient as it is easier to control and optimize producer gas for combustion than it is to optimize raw biomass. Using gasification also provides small amounts of charcoal as a by-product. Charcoal commands a good value in the marketplace. Today, a number of plants in India and overseas are seriously looking at using biomass for their boiler as well as their other heating and drying applications. The economics of biomass are fairly simple. At the current prices of biomass (Rs 4-5 per Kg), a 50 T per day biomass based gasification can displace about 10000 m3 of natural gas  or about 10,000 l of furnace oil. Natural gas costs about Rs 40 per m3 and furnace oil about Rs 42 per liter. Thus, biomass based heating would cost Rs 2.5 lacs per day vs Rs 4 lacs approx for either furnace oil or natural gas. This translates to a saving of Rs 1.5 lacs per day for such a facility or over Rs 5 crores per year!  The payback periods for these are in the range 2-3 years. Waste heat recovery / CHP / Cogen Utilization of waste heat has become one of the most sought after ways in the manufacturing sector today. With available technologies, it is today possible to convert both high temperature waste heat as well as low grade waste heat into useful heat or cooling. Of specific relevance here are technologies such as vapour absorption chilling, stirling engine and organic rankine cycle power generation mechanisms. While stirling engine is arguably not yet ready for large scale, reliable commercial use, vapour absorption chilling is a mature technology today, and organic rankine cycle is already a commercially available solution. VAM (vapour absorption) route will be especially useful for factories having significant cooling requirements, either in terms of air conditioning or for chilling/refrigeration. CHP/cogen is already quite prevalent in the sugar mills and distilleries in India. For those facilities that have large amounts of waste heat, CHP is a viable and financially rewarding option. Concentrating Solar Thermal Until a few years back concentrating solar heat was used predominantly for power generation – known as concentrating solar power (CSP). But today, using the same CSP technology as the base but with lesser sophistication, solutions are available that allow concentrating solar heat to generate steam up to 200OC, something that can be used in many process industries for most of their heating purposes. This has opened up the new domain of concentrating solar thermal (CST). CST is today a commercial solution and has already been adopted / implemented at many process industries in the country including diaries, food manufacturing units, large canteens and kitchens and the like. In most case, CST might not be able to replace conventional fuel use fully. It has however been estimated that it could replace up to 75% for many installations. That can be a tremendous saving for companies that are bearing the brunt of fast increasing furnace oil / LPG / diesel prices. Unlike solar water heaters, which is a highly mature technology, CST is still undergoing significant innovations, thus making it possible for companies to have high efficiency and high productivity technology installations in the near future. CST has been shown to have payback periods of less than 3 years in the installations that it is already operating in India. Energy Efficient Heating Equipment I recall a trip I made to a well-known hotel in Chennai where the chief engineer said said that by just replacing one old pump with a new, efficient one, they were able to reduce about 5% overall in electricity costs. This moral is true for many heating appliances and equipment too - be they boilers, furnaces, ovens or kilns. Of course, the decision is usually harder as the capital costs involved in changing over could be considerable, as these heating equipments will usually form the bulk of the cost of the overall heating system. Back-pressure Steam Turbine Back pressure steam turbines are not exactly for thermal efficiency or for reducing your heating costs, but I thought I’d include these here as they still provide a better bang for the buck from the heat generated. Back-pressure steam turbines essentially use the extra pressure and temperature that are inevitably present in the process steam to drive a small non-condensing turbine to generate power. The steam that leaves this back-pressure steam turbine goes on to do the useful work. As mentioned earlier, while it does not provide heat at a lower cost, it provides more value for the same amount of energy used for heating, by generating additional power from it. Summary There, you have it. Using one more of the above six avenues, factories that use significant amounts of heat can achieve significant cost savings while at the same time becoming far more “green” and environment friendly. Wish to know more on how your factory could be made more green through sustainable heating solutions? Send a note to me - Narasimhan Santhanam  ( narsi@eai.in  ).

Costs of feedstock for Biomass gasification

Biomass gasification utilizes renewable feed stocks for liberating the synthesis gas by thermal decomposition under high temperature conditions. Among the factors affecting the production protocol, cost economics play a critical role and is well pronounced in cases when the scale of operation is magnified. Entrepreneurs of gasification technology often make contracts with farmers or traders so as to ensure a price security and timely uninterrupted availability of their concerned feed commodity. In spite of the strategies, price fluctuations in gasification feed stocks have been witnessed, for instance cost of rice husk was at Rs: 600/tonne in 2009 but has steeply increased to Rs 1800/tonne by the end of 2010 and such an extreme volatility in market prices causes a concern to buyers and affect the final price of the power/unit produced by biomass gasification technology. Lack of price security has produced an unique trend in gasification where the venturers start their own farms for feed stock production which they claim that it can cut costs by two-third of the actual cost and seems to be working well in particular with dedicated energy crops. Gasification technology is well balanced economically as entrepreneurs have a scope to sell biochar by-product which fetches good market price to compensate for the cost procurement of the feedstock. Socio-economic and technical factors continuing to challenge the progression of gasification but the productivity makes it a superior choice that cannot be camouflaged.

Current Status of Biomass Gasification in India

India has initiated its power generation from renewable sources by several different principles namely gasification and combustion. Biomass gasification is carried out at different power capacity levels ranging from 25 kW to 2 MW and above. When a comparative analysis is made between combustion and gasification of biomass, the former technology is best operational under high capacity installations while the inverse is true for the gasification. This peculiar advantage seen in gasification to operate at smaller ranges makes the technology suitable for adoption in rural and by small entrepreneurs where power generation is required rather than efficiency. The technology even though best functions with high range installations of 2 MW, its utility is obstructed by the demand for a series for engines and India has less than 10 installations so far. Gasification technology is really ideal where resources are randomized and adoption of any other technology is tedious on a financial scale. Gasifiers are flexible to operate which makes the user to follow any technology depending on his requirements to a limited extent.

Decarbonizing India’s Energy Sector by Biomass and Biofuels


This post is a part of DIL Intelligence series from Energy Alternatives India (EAI), India's leading climate-tech consulting firm.

DIL stands for Decarbonization for India's Leaders and provides comprehensive market intelligence and updates to Indian corporate leaders on prominent decarbonization efforts across the Indian industrial ecosystem. DIL is provided by EAI's strategy consulting team. More about our consulting from here.


In India, 22% of the total energy supply is renewables, with biomass contributing 85%. Biomass use is shifting from traditional residential heating to power production. Biofuels represent less than 1% of transport fuels, with bioethanol at 3% of gasoline consumption. The biomass market is projected to reach INR 32,000 crore by FY2030-31. India produces 450-500 million tonnes of biomass annually, with a surplus of 230 MMT/year. Biomass-derived energy constitutes 32% of India’s primary energy use. The biomass pellet manufacturing capacity is 2.38 MMT, with 83,066 MT co-fired in 39 thermal power plants.

Reliance Industries Limited (RIL) is transitioning from fossil fuels to renewable energy, including biofuels, for its energy demand. This involves using bio-pathways to fix CO2 and recycling materials across value chains. RIL plans to set up around 100 Compressed Biogas (CBG) plants over the next five years, consuming over 5.5 million tonnes per annum of agricultural residue and organic waste. This initiative is projected to reduce nearly 2 million tonnes of carbon dioxide emissions annually. In essence, RIL’s decarbonization strategy involves renewable energy, biofuels, recycling, and CBG plants.

Thermax, an Indian energy and environment engineering company, is decarbonizing its manufacturing processes using biomass and biofuels. Its subsidiary, TOESL, installs biomass-fired plants and sells steam. Thermax’s solutions include the Atmospheric Fluidised Bed Combustion Boiler, capable of using various fuels including coal, lignite, rice husk, petcoke, spent coffee ground, washery rejects, low ash coal, paper sludge, roasted chaffs, DOB, bagasse, pith woodchips, coffee husks, mustard stalk, cotton stalk, and char. Thermax has secured an order worth over Rs 500 crore to set up five bio-CNG plants across India, with a capacity to produce 110 Tonnes Per Day of bio-CNG, utilizing local feedstock exceeding 1,000 TPD. This initiative contributes to the decarbonization of manufacturing processes.

The shift from fossil fuels to renewable energy sources is a key aspect of the company's strategies. This transition is driven by the need for cleaner energy sources and the potential economic benefits of renewable energy. Development of advanced biofuels like bioethanol, biodiesel, and biogas from sustainable feedstocks like algae and dedicated energy crops can further reduce reliance on fossil fuels and enhance energy security.

Looking ahead, the focus will be on enhancing the efficiency of biomass and biofuel technologies, developing second-generation bioconversion processes, and ensuring the sustainable sourcing of feedstocks. The potential of biomass and biofuels extends beyond just energy production. It opens up opportunities for waste management, rural development, and job creation, contributing to a circular economy. Companies like Reliance Industries and Thermax are pioneering this transition, demonstrating the viability and benefits of these renewable energy sources.

Following my previous post on the industry perspectives on the various methods that have to be adopted for sustainable feedstock procurement (http://eai.in/blog/2011/12/industry-perspectives-and-strategies-for-effective-biomass-feedstock-procurement.html), today’s article showcases the various feedstock (emerging) that could be used as  a potential source for biomass-based power generation. As you might be well aware, the first generation feedstock such as sugars, starches from wheat, sorghum, sweet potato etc are not widely used for bioenergy production owing to the food-fuel conflicts. Similarly, even the second generation feedstock such as mustard are not being used in a big way for bioenergy production. These days, more focus is being thrown on the advanced feedstock such as the third-generation biofuels ( these seek to improve yields through improving the feedstocks themselves instead of the processes). These feedstocks include those sources that promise to generate greater than 500 gallons of oil per acre per year. Examples include palm oil and algae oil, rapeseed and jatropha oil, grasses (switchgrass, miscanthus), trees (willow), halophytes (saltwater plants). Provided are some details of the emerging biomass feedstock such as camelina, miscanthus and bamboo and their potential to perform as a bio-fuel. Miscanthus: Miscanthus, also known as Elephant grass can grow up to 3 meters high and it is native to tropical and sub-tropical regions of Africa and South Asia. Miscanthus is mentioned as a biofuel crop because of its relatively high dry matter yields across a range of environmental and soil conditions. The Miscanthus genotype most commonly recommended for biofuel production is a sterile hybrid (Miscanthus x giganteus) believed to be a M. sacchariflorus x M. sinensis hybrid. Miscanthus utilization in the biofuel industry is primarily for combustion in power plants – it has the desirable properties of low water and ash contents. Current research is focused on its potential as a biomass crop for direct combustion and for lignocellulosic conversion to ethanol. Giant miscanthus has been studied in the European Union and is now used commercially there for bedding, heat, and electricity generation. Most production currently occurs in England but also in Spain, Italy, Hungary, France, and Germany. Recently, Japan and China have taken renewed interest in this native species and started multiple research and commercialization projects. In the United States, research began at the University of Illinois at Urbana-Champaign in 2001 and has expanded rapidly to other U.S. universities. However there is currently little published information on giant miscanthus yields in the United States. Bamboo: Recently, bamboo has received increasing attention for producing biofuel because of its easy propagation, vigorous regeneration, fast growth, high productivity and quick maturity. Bamboo is an efficient user of land, and produces more biomass per unit area than most tree species. But the process of converting bamboo cellulose into liquid fuel is difficult to execute efficiently because of the extraordinary density of the plant.  However, new research from Mississippi State University hold clues for how scientists can learn to more easily break down bamboo, and thus more efficiently extract biofuels from all other cellulose sources using the bacteria from pandas’ waste. If the researchers are successful, the manufactured enzymes could be used in a new, much cheaper and more efficient process for converting bamboo and other woody plants into biofuels. Fuel properties and potential as a bio-fuel of different bamboo species:

Species Moisture content Density Ash content Energy content
% g/cm3 % MJ/Kg
B.pallida 44 0.61 1.91 18.63
B.tulda 37 0.65 1.92 18.61
D.asper 37 0.77 4.23 17.92
D.membranaceus 43 0.62 4.99 18.81
G.apus 35 0.76 2.00 18.14
Camelina Camelina, an oilseed, is a rotation crop for wheat that can be established on marginally productive land. It is an annual, short season plant. Biofuel from camelina is an ideal jet fuel substitute. Camelina has a number of advantages over its competitors, including using far less water, thus allowing it to be grown on marginal land, thereby not taking food acreage out of production. Furthermore camelina has a relatively short growing season of 80 to 100 days, requires no special equipment to harvest, and the silage remaining after processing can be fed to livestock and poultry, with the added side benefit of increasing their omega-3 production. Camelina is increasingly emerging as a prime biofuel source and thus attracts investment worldwide, as global demand for aviation fuel for passenger flights is now more than 40 billion gallons annually. In the earlier of this year, USDA announced two Biomass Crop Assistance Program (BCAP) project areas devoted to developing camelina as biofuel in several states, including Montana. USDA's Risk Management Agency (RMA) has also recently announced a new pilot program of insurance for camelina beginning with the 2012 crop year.

Future Feed-in-Tariff Trends for India – for Wind, Solar and Other Renewable Power Sources

It is an open secret that renewable power requires incentives - these usually are in the form of capital subsidies, tax incentives and most importantly, via feed in tariffs. It is a million dollar (make that Billion Dollar) question what the future of feed in tariffs will be for the mainstream renewable power sources. I picked up some resources on these. Wouldn't say they provide a peek into the future, but at least one of these try telling us how the government arrives at these numbers, so that will provide us with some clues.

 Most of us have come across the gobar gas – literally meaning gas from the cow. It is the same as what is called biogas. This is the gas that is released when bacteria feast on organic matter – typically human and animal feces – and release a gas that is about 50% methane. While biogas had predominantly been used earlier for heating purposes, its use for power production is also beginning to show a marked rise across the world, and in India too. How is power produced from biogas? The process is actually quite simple. Step 1 is generation of biogas. This is done typically using what are anaerobic called digesters. Animal (or human) waste is fed into the digester, where the microorganisms (called methanogenic bacteria) act upon it. Depending on the type of digester, it could take anywhere between 10 days to 15 days for the waste to have been "digested" by the bacteria and the release of biogas. The biogas thus produced can be used in IC engines specially devised for the use of biogas. These engines are similar in working principles to diesel engines and natural gas engines. These engines produce electricity from biogas. A bit of observation will lead us to easily understand why this concept will be of enormous interest to specific industry segments. Two segments stand out - industries that employ large numbers of animals and sewage treatment plants that treat human waste. Both these segments have started benefitting from this concept; as a result, we have a few STPs (sewage treatment plants) already generating power from the sludge generated (one of the STPs at Chennai, at a town called Nesapakkam, generates about 500 kW of power from the waste, and uses the power generated for all its electricity purposes). Some numbers will help understand the potential available for power generation from biogas. The cow population of India (about 225 million) alone generates about 800 million tons of wet dung which translates to about 150 million T of dry weight. 1 Kg of dry cow dung can generate about 1.2 kWh of electricity (it can generate the equivalent of about 4 kWh thermal). Thus, if all cow dung were converted to electricity, that would be 1.2*150*1000 million kWh = 180 TWh. India generated a total of 855 TWh in 2011-12. This implies that cow dung, if entirely converted to power, would have produced about 20% of total India's power! If the waste of other cattle and human waste were also taken into account, this could be about 30%. That is an awesome number. Of course, these data hide the actual difficulty in converting even a small portion of animal or human waste into electricity, owing to the infrastructural and social problems associated with these. All the same, waste -> biogas -> power is quite practical to a whole host of industries for whom such waste is available on premises. More information about waste to energy in general in the Indian context, is available from EAI's waste to energy resource section. Some of the following YouTube videos provide a more visual account of how to generate biogas from organic waste: Biogas from food waste - ARTI - http://www.youtube.com/watch?v=BGSl72xZHNk&feature=related Bio-gas from kitchen waste and bio mass - http://www.youtube.com/watch?v=uppVZGS7bYI&feature=related Biogas from Vegetarian Food Waste - http://www.youtube.com/watch?v=NZFrPZZIFTs&feature=related Biogas from Human Waste - http://www.youtube.com/watch?v=_m1nr2v5S8o And while on sewage, human waste and toilets, etc, a couple of interesting articles on things are emerging New toilet technology after 150 years of waste The seat of power - Better sewage treatment is the latest thing in clean energy Also check out: EAI Consulting for Bio-energy & Biofuels, Bioplastics & Other Biomass-based Value Added Products

How Punjab Will Benefit from All Its Agricultural Residue- A Case Study

Agricultural residues never go to waste. Not when they can be used for generating energy. In this context, the government of Punjab, India, plans to produce about 1,000 MW of green energy from livestock residues by 2015. When you think about it, this has huge economical and environmental benefits. In a region where large quantities of cattle manure become a major pollutant, this could be seen as an opportunity that could open a lot of doors. Aside livestock residues, the state also generates nearly 21 million tons of rice stalks and similar biomass plant wastes annually, which can all go into the production of green power. The state government is thus planning to make renewable resources as the source of their power to contribute 10% of its total energy production in the next five years. It is worthy to mention that Punjab already runs a biomethanation facility with a capacity of 1 MW, in a location close to Ludhiana. The facility uses methanogens (microbes that produce methane as a metabolic by-product) for the manufacture of methane gas. It currently uses 235 tons of cattle wastes to generate 18,000 kWh of electricity in addition to producing 45 tons of organic fertilizer every day. Also, the Punjab Energy Development Agency has developed 318 MW of green power projects, which includes the Ludhiana plant, till date. These projects comprise 37 MW of small hydro facilities, 28 MW of biomass power facilities, 250 MW of biomass co-generation facilities and 2 MW of solar projects. The agency also develops 132 MW of green power projects currently, which include 11 MW of hydropower, 100 MW of biomass co-generation and 20 MW of traditional biomass. If everything goes right and operational, the state will generate 700 MW of green power by 2012. That’s big! It is worthwhile to note that the planters are also getting an income of nearly RS. 4,000 per acre every year in the process of marketing agro wastes to biomass facilities.

Industry Perspectives and Strategies for Effective Biomass Feedstock Procurement

===========================================

Are you looking to get energy security for your company through reduction in the use of diesel, furnace oil, LPG and costly grid power? EAI can do a feasibility study for the use of solar PV & thermal, biomass for heat and power, waste heat recovery and energy efficiency to dramatically cut down fossil fuel use and reduce your energy bills. See EAI's SURE-FIRE offering for more.

 ===========================================

One of the most critical bottlenecks for biomass power plants is the supply chain bottlenecks that could result in non-availability of feedstock. A related problem is the volatility, or more precisely increase, in the feedstock price. Both these could render the project unviable. Highlighted in this article are some of the industrial perspectives in overcoming barriers for procuring a balanced feedstock supply. EAI’s research with industry experts suggest that there is no established biomass value chain that exists in India for the procurement and transportation of the biomass feedstock. Typically, the facility staffs  from a biomass gasification plant acquires biomass from several to dozens of small-scale biomass suppliers on a relatively informal, non contractual basis; although some have considered the use of aggregators, there is no data or proof available from the Indian biomass gasification companies that have engaged such a service as yet. The biomass procurement model that is typically followed in India is discussed below: Route #1 – Biomass Producer -->Transport Contractor --> Biomass Collection Centres (BCC’s) --> Power Producers The biomass producer i.e. the farmers/mill owners hands over the feedstock to a transport contractor who in turn delivers the feedstock to the biomass consumers or BCC’s. The BCC’s (managed by the biomass consumer) pay the farmers and the power producers collect the feedstock from these collection centres as and when required. At some instances, the farmers deliver the feedstock in the power producer’s facility and get directly paid for it. Route #2 - Biomass Producers --> Waste Processing Mills -->Biomass Power Producers For feedstock where further processing is required, the farmers/mill owners deposit the feedstock in waste processing mills. From the waste processing mills through a transport contractor the feedstock is deposited in the BCC’s or directly in the power producer’s facility. In some cases, especially in briquetting, the processing is done in the collection centres itself where a mobile briquetter is taken and the briquettes that are processed are directly delivered to the facility or collected by the power producers. Key Strategies to be Followed for Effective Biomass Feedstock Procurement EAI’s interactions with the industry reveal that the following strategies have to be adopted   in order to bring both the availability and price of biomass under control:
  • Security should be addressed by obtaining a written formal supply agreement with a reputable, local supplier. A five-year signed supply agreement with pricing and minimum volumes can go a long way in helping to secure necessary financing. A bioenergy project that is totally reliant on only one source of feedstock will be at risk, so two supply contracts are even better. This will also allow one to negotiate a better feedstock price, as the supplier will benefit from a long-term relationship and a guaranteed market. An interested lender needs to know that both the feedstock supplier and bioenergy processor are committed to the project.
  • It can be beneficial to hire an independent professional to verify one’s biomass supply projections and double-check that the feedstock supply is sustainable over the long term
  • Backward integration and own captive biomass source (one company, Orient Green Power, is even trying out a novel technique of going for energy plantations on their own wind farms)
  • According to the Washington based biomass supply company ‘Powerstock’, for a well-managed supply, an inclusive definition of biomass is needed. The company is also taking efforts to educate the public on the value of well-managed, productive forests.
  • The bottom line of feedstock security is composed of several aspects: grower relations, harvesting, marketing, equipment utilization, proprietary techniques and agricultural economics. Hence it's important to manage the entire process from seed to market.
  • The supply sector needs to make the transition from a residues-based approach to an integrated, dedicated feedstock supply system using energy crops, plus residues.

Potential for Biomass Power in India

Biomass based power generation is a choice of reality under the geographical regions where a sustainability exists in the flow of biologically raw materials for the production of power and India is one of the most notable universal giants for the production of biomass based power which can be best understood from the estimates of its biomass availability and the power produced from it. India has biomass production of 546 million tonnes per year from the agricultural sources alone to generate electricity at a capacity of 17,982 MW and its overall production of power from renewable sources stands at 34961 MWe in 2010.A calculated annual growth rate for the next decade realistically and optimistically is above 42,000 MWe and 48640 MWe respectively. The development of biomass based power is further enhanced by the Government regulatory policies by declaring duty exemptions’, tax breaks and financial incentives etc. The cost of producing electricity from biomass is affordable at Rs: 2.25-3.25 / kWh. In spite of all these attempts biomass based power generation is at its infant stage because of hindering factors such as feedstock availability, transportation, price volatility etc. India to emerge as a role model must utilize its renewable energy sources to a large extent, develop dedicated energy crops, establish end user market for co-products such as charcoal, biochar, activated carbon, and implement energy efficient technology for economically feasible power generation on a massive scale.

Mitsui, a leading Japanese conglomerate, has recently invested ₹4.1 million in Punjab Renewable Energy Systems Pvt. Ltd. (PRESPL), a company focused on collecting agricultural residues and converting them into biomass briquettes and pellets. This investment underscores the growing potential of the Indian biomass sector, which is expected to witness significant growth in the coming years.

The Indian biomass market is estimated to be valued at around ₹50,000 crore and is projected to reach ₹1,00,000 crore by 2025, driven by factors such as the Increasing demand for renewable energy, Growing awareness of environmental concerns, and  Supportive government policies.

The Indian biomass sector is also witnessing a surge in international collaborations, with several prominent companies entering the market through partnerships and alliances. For instance,  Aramco, a prominent oil and gas company, joins forces with ReNew Power, India's largest renewable energy company, to explore opportunities in developing and deploying low-carbon technologies, including biomass-based power solutions. This collaboration signifies the growing interest of leading energy giants in exploring cleaner alternatives. 

Additionally, Danish Biogas's collaboration with the Maharashtra Energy Development Agency (MEDA) brings together expertise in advanced biogas technologies with experience in promoting renewable energy and rural development in Maharashtra. This partnership contributes to a more sustainable waste management system through biogas generation..

These strategic partnerships are just a glimpse into the exciting developments propelling the Indian biomass sector forward. The government is also playing a crucial role in accelerating its growth through supportive initiatives like subsidies for setting up biomass power plants and briquette/pellet production units, promoting dedicated energy crops and efficient residue collection systems, and providing tax benefits for biomass projects. Investments in research and development are also being made to improve conversion technologies, optimize feedstock utilization, and develop cost-effective biomass solutions.

Navigating this complex ecosystem requires a comprehensive understanding of the key players involved. The Indian biomass value chain comprises various stakeholders, including biomass producers like farmers and forestry companies, collectors and aggregators responsible for managing feedstock collection and storage, processing and conversion companies that transform biomass into usable forms, original equipment manufacturers (OEMs) who create machinery for the sector, suppliers providing essential goods and services, power plants and industries utilizing biomass-based fuels, and government agencies responsible for regulation and promotion.

Beyond the core value chain, the adjacent value chain plays a crucial role in supporting the sector's growth. This includes financial institutions offering loans and investments for biomass projects, research institutions and universities engaged in R&D advancements, and non-governmental organizations (NGOs) promoting sustainable practices and advocating for policy changes.

Indigenization remains moderate to low currently, with reliance on imported technologies and equipment. However, government initiatives and rising demand are expected to gradually increase domestic capabilities in the coming years.

Primary Routes for Power from Biomass

The three primary routes for biomass to power are: Combustion, Gasification and Anaerobic Digestion. Combustion is easy to understand – instead of using coal or other fossil fuel, use biomass to produce steam that runs a turbine. Combustion of biomass for power could either be in the form of co-firing (when it is burned along with coal) or pure play biomass based combustion. In the case of gasification, the biomass is first gasified and this gas turn produces power in a gas engine. Anaerobic digestion is usually applied to biomass that typically have a high amount of water in them (anaerobic digestion is most used for treating organic waste such as kitchen waste and sewage waste into energy). Under this route, microorganisms act upon the organic matter present in the biomass under anaerobic (absence of air) and convert it into biogas. An emerging route for biomass based power is pyrolysis. In this, the biomass is rapidly heated to 450 - 600 °C in absence of air, and results in a bio-oil called the pyrolysis oil, which can in turn be used for firing the boilers. Typically, 50 - 75 % (by weight) of the feedstock is converted into pyrolysis oil. Pyrolysis as a method for power production is not well established currently in India or elsewhere in the world. Typically pyrolysis plants work well beyond 2 MW scale, while gasification plants work well until 2 MW scale, at the current technological progress. Thus, it can be said that pyrolysis takes off where gasification ends. Also check out: EAI Consulting for Bio-energy & Biofuels, Bioplastics & Other Biomass-based Value Added Products

Prominent biomass feedstock for gasification

Biomass for power generation by combustion or gasification is normally variable in its chemical composition of electron rich reactants, ash content, moisture, sulphur and nitrogen content etc. As a result, selection of the most convenient feedstock is an issue of debate. The degree and diversity of contaminants strongly influence the production and purification of synthesis gas in gasification while they tend to have a minimum effect in the combustion process. Independant of these disturbances virtually any raw material applied in power generation process should be a matter with potentials. In India, a vast array of feed stocks are utilized for power generation but the most wide ones are farm and mill wastes, woody trees, energy plantations and other green manure crops. Preference is made on the basis of availability, cost, bulkiness of the material, pre-processing, storage etc. Biomass used in India yields varying level of energy but it is also the gas engine and generators whose efficiency equivalently determine power generation.

REC Price Band Revised

The Central Electricity Regulatory Commission(CERC) has announced the floor and forbearance prices to be used for solar/non-solar projects from the FY 2012-13 upto 2016-17. The prices set are shown in the table below

Non Solar (Rs.) Solar (Rs.)
Prices (2012-2017) Current % Reduction Prices (2012-2017) Current % Reduction
Forbearance Price 3300 3900 15.38 13400 17000 21.18
Floor Price 1500 1500 0.00 9300 12000 22.50
Background Earlier, the CERC had proposed a few changes (refer table below) to be made to the REC prices and invited comments/suggestions on the same.
Non Solar (Rs.) Solar (Rs.)
Proposed Current % Reduction Proposed Current % Reduction
Forbearance Price 3480 3900 10.77 13690 17000 19.47
Floor Price 1400 1500 6.67 9880 12000 17.67
  The final prices to be enforced from April 2012 were arrived at after considering the comments/views of stakeholders and participants at the public hearing on the proposed floor and forbearance prices. As can be seen, the final prices decided upon are considerably lower than the earlier proposed prices. Analysis Financial feasibility studies of power plants under the REC mechanism almost always consider the floor price for calculating returns. With this in mind, the evaluation of REC for the primary renewable energy generation systems looks quite healthy.
  • Non-solar – the floor price remains unchanged. Thus biomass/wind generators are expected to get the same minium revenue as they have been getting earlier.
  • Solar – the floor price has seen a cut of about 23% from current levels. Although this might seem drastic, it is not likely to have a significant impact on solar power projects (refer section below).
  APPC – Non preferential tariff and REC CERC stipulates that for a project to be eligible under the REC mechanism, the power producer has to sign a PPA with the state utilities at a price equal to the APPC price. The APPC price for a state for a particular time period is determined by the State Electricity Regulatory Commissions(SERC). Looking at the current APPC prices in various states, a combination of REC and a PPA signed at APPC rates seems comparable with the preferential PPAs signed with the state utilities. For example,  let us consider a solar PV plant to be setup in Tamil Nadu where the APPC price for 2011-12 is Rs. 3.38/kWh. Under REC regulations, if a RE developer were to get the floor price for the solar REC, the income for the solar PV plant would be Rs. 12.68 /kWh (Rs. 3.38 + Rs.9.3). Another case is Rajasthan, which has a very high potential for solar PV – where the income would be Rs. 11.9 /kWh. In comparison, under the phase 1 (batch 1) of JNNSM, the average price settled on through the reverse bidding process was  about Rs. 12.5 per kWh. As can be seen, these prices are comparable to tariff set through reverse bidding under batch 1 of the JNNSM scheme. Prices can only go higher APPC prices are set based on the cost of power generation from fossil fuel based power plants. It is highly likely that this price would increase in the future due to the increase in fossil fuel prices and scarcity of supply. This ensures that the APPC prices would continue to increase for the foreseeable future, thus ensuring higher year on year returns under the REC mechanism provided the PPA signed with the state utilities has provisions for purchase at floating APPC prices rather than fixed price. The table below gives a comparison between preferential tariff (reverse bidding under JNNSM) and REC mechanism for a plant in Tamil Nadu. The following assumptions were made for the sake of calculations
  • Average bid price under phase 1 batch 2 of JNNSM could be around Rs. 12.5 /kWh(on the higher side)
  • APPC prices could rise by 15% annually (base price used is that of Tamil Nadu) - reasons for this were mentioned earlier.
  • REC price after 2016-17 period (i.e. from FY 2017-18 onwards) is reduced by 25%

As can be seen from the above table, the REC mechanism is quite comparable, if not better when compared to the assured tariff provided by NVVN over 10 years of operation of the solar powerplant. Overall, the REC mechanism can clearly drive the solar market, provided the Renewable Purchase Obligation (RPO) is strictly enforced by the various SERCs.

REC Trading – November 2011

The REC trading for the month of November concluded yesterday. Figures reveal that the trading has increased significantly both in volume of RECs traded as well as the price. In total 105,527 RECs were sold. Keeping with the trend of previous months, IEX had a higher share of the market with 96,154 (90%) RECs traded while PXIL saw trading of 9,373 (10%) certificates. The large volumes of trading indicate that the obligated entities are trying to fulfil their RPO as soon as possible as REC prices are showing an upward trend. The price of REC varied between the two exchanges - IEX and PXIL. Non-solar RECs closed with a price of Rs. 2,900 at IEX while the RECs sold at Rs. 2,800 at the PXIL. At the IEX, the prices have seen a 7% rise over those paid last month where the trading price was Rs. 2,700 per REC.

Interestingly, there are 43 buy bids for solar REC; this suggests that the solar REC market is gathering steam. This growing interest suggests that solar projects being planned based on REC may soon be bankable and we could see a trend in developers going for the REC mechanism during the interm period between now and the second phase of the National Solar Mission. Solar developers have another reason to rejoice as well as maintain a shrewd view on the Solar REC market. This month saw the accreditation of the first Solar project under the REC mechanims - an 8.5 MW solar project located at Jalgaon, Maharasthra developed by Jain Irrigation Systems. This project's viability has to be closely followed over the coming trading sessions as the REC certificates generated from the project slowly start coming up for sale. In total there are about 244 projects registered under REC with an aggregated capacity of 1551.92 MW (this excludes the lone solar project that recently got accredited). Conclusion The REC market continues to impress with higher sale prices and volumes. The REC prices are expected to rise over the coming months given the fact that there only 4 months left for RPO compliance. However, the price as such is expected to rise only gradually and not at the high rates seen over the year. The registration of a solar project under the REC mechanism might open the flood gates for more solar projects depending on the performance of the solar RECS. This could lead to a pradigm shift in the solar project development in India, which up until now has looked up to the state/central solar policies as the only source for project viability thereby reducing the cost of solar power in India and accelerating the road to grid parity.   Also check out: EAI Consulting for Bio-energy & Biofuels, Bioplastics & Other Biomass-based Value Added Products

REC Trading – September 2011

The REC trading for the month of September concluded recently. Trading figures reveal that the trading has increased significantly both in volume of RECs traded as well as the price. In total 46,362 RECs were sold. Keeping with the trend of previous months, IEX had a higher share of the market with 41,385 (89%) RECs traded while PXIL saw trading of 4,977 (11%) certificates. The large volumes of trading indicate that the obligated entities are trying to fulfil their RPO as soon as possible as REC prices are showing an upward trend. The most encouraging part of the trading was the price paid for each certificate. The price of REC grew to Rs. 2300 from Rs. 1800 last month.

Interestingly, there are 7 buy bids for solar REC; up from the lone buy bid last month, although this is promising, it highlights a serious issue. As with the previous months, there are no solar RECs available as no projects are registered under REC. This is a worrying trend and is going to put immense strain on the obligated entities to fulfil their solar RPO. The reasons for lack of solar projects registered under REC could include

  • Higher payback period for solar projects
  • REC prices guaranteed only up to 2016-17
  • A combination of the above two greatly reduces the bankability of solar projects
Conclusion The increase in REC trade volumes and price is very encouraging. It shows that the mechanism is a viable revenue route for developers who have not signed any preferential PPA. The demand for REC certificates is bound to keep increasing as more and more obligated entities try to fulfil their RPO in the short time span available. This is scheduled to push the REC price even further which in turn could lead to REC prices hitting their forebearance highs in the coming months. Finally more effort needs to be put in to ensure that there is sufficient supply of solar RECs in the market.

Mr. Palekar gave a very insightful speech on the development of the Solar sector in India, especially the grid-connected projects selected under the 1st part of the first phase of the JNNSM. He touched upon the following aspects of these projects
  1. Growth drivers – Policy/PPA
  2. Project Implemention – Financing, Technology selection and execution.
He mentioned that while many of the project developers are choosing thin film technology, these projects could face problems when they approach banks for financing. The reason for this is that world over thin film technology is used by only about 20-30% of all the projects. Overall, he felt that the MNRE is doing a very good job in bring confidence in the industry and in removing any uncertainty regarding the seriousness of the National Solar Mission.

That concluded the 3rd edition of the Renewtech India conference. The 4th Renewtech India conference is scheduled for 16-18 February 2012 at the same venue – Bombay Exhibition Centre, Goregoan, Mumbai.

Rice husk used for power in one of India’s poorest states- A case Study

Whoever thought rice husk can generate power needs a medal! Considering how much rice husks go to waste in a country where rice is the staple food, it is comforting to know fossil fuels are not our only resort for power production. Thanks to Manoj Shinha, a renewable energy entrepreneur pioneered using discarded rice husks as biomass to provide energy to Bihar, one of India’s poorest states. Mr. Shinha along with his colleagues Gaynesh Pandey, Ratnesh Yadav and Charles W. Ransler developed Husk Power Systems to address the situation of poverty in their home state of Bihar. Many villages in India live off the grid in the darkness, this new advancement means that they need not depend on grid for electricity, rather generate their own clean, affordable electricity.The company generates and sells electricity for a price that is less than half of what the villagers pay for kerosene. This was possible because the whole concept is focused on research and development investment to simplify energy production and transmission, such as using bamboo instead of cement posts to install power lines.And, since communities no longer use kerosene, wood or dung for electricity, this way of electricity generation lowers the environmental and health hazards. In addition, rice husk ash, a byproduct of the gasification process, can be used for concrete production thus reducing the amount of high-carbon Portland restless leg syndrome cement.On average, a single power plant serves 400 houses, replacing 42,000 liters of kerosene and 18,000 liters of diesel yearly. As of August 2010, H.P.S. has sequestered 50,000 tons of carbon dioxide. Currently, they have installed over 60 mini-power plants that are 100 percent biomass-based which supply power to over 25,000 households in more than 250 villages.With the market opportunity in mind, they aim to expand their business to bring clean electricity to Indian villages by installing 2,000 new plants by 2014 beyond Bihar.

Tamil Nadu’s Biomass Power Plans – Energy Plantations is the Answer?

Biomass is one of the renewable energy domains in which Tamil Nadu could have significant potential for progress in future. Estimates suggest only about 10% of the potential has so far been utilized. Of course, the lack of a robust supply chain that make create supply and price security is a problem as much in Tamil Nadu as it is in the rest of the country. Some inputs and updates for biomass power in Tamil Nadu are provided below.

  • Potential for Biomass based power in Tamil Nadu is 1589.9 MW (1160 MW based on agricultural waste and 429.9 MW from forest and wasteland cultivation).
  • 22 biomass power plants with total installed capacity of 169 MW are in operation.
  • Ten biomass power plants with totaling to 120 MW, with over 80% plant load factor, have faced temporary shut downs owing to unviable tariff rates and increasing feedstock cost.
  • Biomass power producers association has approached Tamil Nadu Electricity Regulatory Commission (TNERC) with a request to revise the tariff and offer higher annual tariff escalation. The viable rate for operating biomass power plants in years to come would run beyond Rs 6.50/kWh, but the current tariff of Rs 4.5/kWh is in no way adequate to sustain the projects in the long run.
  • Tamil Nadu Energy Development Agency (TEDA), along with Tamil Nadu Biomass Power Producers Association, has been actively involved in promoting large scale energy plantations in marginal / waste land in the state with high potential crops.
  • The Tamil Nadu Biomass Power Producers Association suggests that energy plantation would not only serve to provide cheap and continuous feedstock supply for power plants, but it would also improve the quality of life of the rural population. Estimates suggest that a 10 mw biomass power plant can ensure livelihood of over 2,000 marginalised families. They can be employed in collection, transportation, cutting, chipping of biomass and cultivation of wasteland with energy plants like Juliflora, Bheema Bamboo etc.
So, it looks like Tamil Nadu is betting significantly on energy plantations for a viable biomass power sector. Let’s hope they have got it right. Also check out: EAI Consulting for Bio-energy & Biofuels, Bioplastics & Other Biomass-based Value Added Products

The man propelling the bio-energy movement in India – PRESPL

Welcoming Lt Col Monish Ahuja to CLIMAFIX SUMMIT 2022 - the 1st summit for Indian climate tech startups. I'm sure you have heard the saying, "Water, water everywhere, not a drop to drink" That applies quite well to the Indian agricultural residues as well. Hundreds of millions of tons of agro waste around the country, but very little available for the industries to use. And worse, a good portion gets burnt on the fields because the farmers do not know what to do with them. So where's the challenge? What is broken in this system? To a significant extent, logistics, or rather the lack of it. Securing and transporting millions of tons of agricultural waste from hundreds of thousands of farmers and transporting it reliably to end users is not rocket science. But it is systems science. Discipline science. Or patience science, if that term is more endearing to you. In EAI's decade long work in the bio-energy sector during which we consulted for dozens of clients including the likes of GSK (#Horlicks division, now part of Unilever), we have seen how unorganized the agro-waste supply has been, except for bagasse coming straight from large sugar mills and to a lesser extent saw dust from plywood factories. It is a complex challenge of logistics, societal & local traditions, and of course the omnipresent politics. The sector needed someone who could wade through all these, build an efficient system and evolve an organized biomass supply chain. Enter Lt Col Monish Ahuja. Army discipline, Systems thinking. Business acumen. These characteristics have helped him build Punjab Renewable Energy Systems Private Limited (PRESPL) into a force to reckon with countrywide in industrial biomass supply. PRESPL is today is one of the few organized players that has the ability to provide industrial decarbonization on scale through biomass, supplying thousands of tons of agro-waste based biomass every day to industries. I remember sitting with him in his office in Navi Mumbai a few years back when he patiently took me through the process by which he was building an effective front-end logistics system while also putting together a scalable digital back-end system. While coming out from the meeting, I thought - finally, here's someone who appears to be just what the doctor ordered for India's bio-energy sector. Since then, his company has - not surprisingly - grown and grown. Hats off to Monish, and we are proud to have him as one of the experts who will share his insights at the CLIMAFIX SUMMIT 2022, India's first climate startup summit, Nov 25 & 26, Chennai, organized by the Climate Startup Intelligence division CLIMAFIX of EAI (Energy Alternatives India) & Energy Consortium - IIT Madras Welcome Monish, and here's hoping you inspire more of your breed - and soon.

VC / PE Perspectives and Opinions on Biomass Power

Indian VCs have not really done a good amount of investing in cleantech. Cleantech perhaps  is not really a VC game as it is more of an engineering related discplie that does not offer the types of scalabilitiees that VCs desire or the exit periods. VCs also do not understand cleantech well enough to take calls. Many cleantech deals, especially in the power segment, are PPA based, with limited upsides, not typical VC games. Many cleantech and renewable energy startups require capital that is much higher than what VCs can typically offer to invest. Predictions for Cleantech VC in 2011 - Kachan & Co.'s Dallas Kachan looks at what 2011 will have in store for cleantech (http://alwayson.goingon.com/node/66783 ) Sustained worldwide venture capital investment will continue to cede importance to corporate and non-institutional capital. A return to early stage venture investments - predict a return to early stage venture capital investing in cleantech in 2011. Energy efficiency emerges as the clear rock star of cleantech. Biofuel investment could reach former highs. Recycling and mining will attract more investment. Natural gas emerges to threaten solar and wind for utility renewable power generation. China becomes the most important market for cleantech: if you're not selling in China, you won't matter. There is a significant amount of interest among PEs for investments in both traditional and renewable energy. PEs – not surprisingly – are not very keen on risky technology bets in renewable energy, but are OK with business model risks. Some of the PEs (such as IFC, ADB etc) are willing to take fairly long-term views (with over 10 year horizon). Investment sweet spot ( in terms of the quantum) varies from fund to fund, but obviously for most of the blue-chip, it is upwards of $50 million. PEs are well aware of the regulatory and societal bottlenecks that could arise in large-scale energy sector investing (especially for coal-based and large-hydro based sectors). Many PEs are clear that they wish to invest in businesses that can stand on their own revenues (even if takes a while) and are not keen on business plans that rely on getting bought out. Most every PE acknowledged that while they might not like coal, it is here to stay as the largest contributor to power for the foreseeable future. PE arms of organizations such as IFC and ADB, while not shutting out the option of investing in coal-based or natural gas based power plants, have a mandate to decrease their exposures to these “non-green” sectors. What a PE can bring to the table - Many private equity funds have been able to provide not just the financial support required but also strategic support and value-add for the firm’s growth. Disconnect in Valuation expectations - one of the issues faced by PE players while investing in cleantech companies is the disconnect in valuation expectations between the entrepreneur and investor with the buoyant public markets resulting in an increasing buoyancy in expectations! PEs feel that entrepreneurs should take a longer term view while setting their valuation expectations. Currently, 80% of infrastructure projects, and 46% of power projects, are funded by the banking system. So, PEs constitute only a small share of the infrastructure projects. While private equity folks could like IRRs of about 25%, power and infrastructure IRRs is only about 12%. Some private equity companies might wish to play a consolidator’s role as well where they consolidate a diverse portfolio of (say) energy companies such that they win even if 7/10 companies do well enough. Investors such as IFC have specialists/experts in every project to take care of social and environmental aspects. Private equity funds are interested in the macro factors (demand supply gap in electricity et al) as well strategic micro factors. One of the factors that seem to interest PEs is the method for companies to go diversified on green power that is having assets in wind, small hydro, biomass etc together, instead of betting just on one thing alone.

Why Biomass for Power Generation?

Biomass has been used as a source of energy right since mankind started its existence; In fact, one of the predominant energy sources today is biomass. Biomass as a source for power production is not entirely new either. Biomass has been used, in the place of coal, for steam generation at power plants, though in a limited way. Indeed, currently, the predominant method used for producing power using biomass still is the combustion route, At the same time, other processes, such as biomass gasification, which can work at much smaller scales and use the biomass more efficiently are emerging. The newer processes especially biomass gasification based power production, is relevant today especially in the Indian context mainly because of its potential to provide distributed power at rural level, especially for small remote villages that have good access to biomass but no access to grid power, and which require only small scale power production. Biomass based power is also relevant in the context of climate change and global warming as biomass based power production is net carbon neutral. The contribution of bioenergy to the total primary energy consumption in India is over 27% (Source: FAO). This is indeed the case for many other countries, because biomass is used in a significant way in rural areas in many countries. However, the contribution of biomass to power production is much smaller than this percentage – currently, biomass comprises only about 2650 MW of installed capacity, out of a total of 172000 MW of total electricity installed capacity in the country. Besides, biomass power has the following benefits- distributed generation, baseload power, ability to have small, kW scale power production, suited for rural areas and ideal for rural economic upliftment. I believe these are enough to justify why biomass is best suited for power production. Check out: EAI Consulting for Bio-energy & Biofuels, Bioplastics & Other Biomass-based Value Added Products

A 900 MW Power Plant Running on Biomass? It Could be a Reality in Five Years!

I thought I was never going to see the day when a large power plant would run entirely on biomass. You can understand my pessimism when you are told that a MW of powerplant will require about 8000 T of biomass every year. A 300 MW power plant will hence require an awful 2.5 million T of biomass every year. That's a heck of a lot of, well, anything. Well, there are some courageous folks around the world. Drax in the UK, for one. They are building 3x300 MW furnaces on biomass, and are arranging for a 8 million T biomass supply from around the world. (By comparison, India's total biomass based power production - outside of bagasse power - is only about 1500 MW. So the Drax project alone would be about 60% of total Indian biomass installed capacity!) While I am certainly overawed, good news, I must say. If they can operate it sustainably for a few years, biomass power would have definitely reached a milestone. Will be really keen to know how they plan to manage the supply chain. This is what the news report has to say "The vast majority of the biomass will come from North America, but there will also be locally sourced supplies of willow and elephant grass to power the furnaces. "

A Case Study of Clenergen and Yuken’s Gasification Biomass Project

Yuken India Limited, set up in 1976 under a technical and financial collaboration with Yuken Kogyo Company Limited, Japan, is a manufacturer of oil hydraulic equipment. Yuken has achieved one of the fastest growth rates in the Indian oil hydraulics industry, in the last 29 years. Clenergen India Private Limited, a wholly owned subsidiary of Clenergen Corporation, plans to enter into a minimum 15 years Power Purchase Agreement (PPA) with Yuken to supply up to 2.5MW/h, with the rest of the electricity generated being completely sold out to the National Grid System. The biomass power plants with a capacity of 4 MW/h will be installed and begin operation within 10 months upon signing of the PPA. Clenergen India plans to lease up to 800 acres of non arable land near the manufacturing site in order to grow a high yielding species of bamboo as a source of biomass for the gasification power plant. The bamboo produced is asexual, non-invasive, non-flowering plant with a lifespan of up to 50 years and above all, is a product of tissue culture. This is advancement in the sector of renewable energy, in that the cost savings created from the cultivation of biomass feedstock will allow the supply of electricity at a price lower than the current market prices and will also help to extend the industries’ vertical market penetration into these market sectors. This is certainly moving forward. With ever increasing fossil fuel prices, this is the ideal way to deal with the growing needs and the economy.   Also check out: EAI Consulting for Bio-energy & Biofuels, Bioplastics & Other Biomass-based Value Added Products

Agricultural biomass availability in India for power generation

India is primarily an agricultural nation with an extensive cultivation of different types of crops including cereal, pulses, oilseeds, fibre crops, spices and plantation crops. With the cultivation of these crops, availability of residual biomass after economic harvest makes power generation in a sustainable way. These raw materials are normally available in variable quantities depending on the acreage of cultivation, mass of residue part available. The total biomass is 511,041 kT/Yr for power generation. Among them, rice, wheat and cotton constitute a major portion with 160,000,111,000 and 21,000 kT/Yr to generate power of 5000, 3300 and 3500 MW respectively. The total power generation capacity is 17,400 MW. Besides these crops, maize, jowar, bajra, coconut, groundnut, banana, cassava and mustard are also potent generators of biomass for power to an appreciable extent. It is evident from the information stated above that the agricultural resources serve as excellent candidates for the power generation either by combustion or gasification. However it is important to note that these materials are variables by biochemical composition and moisture. So, standardization is mandatory by defining limits to make them appropriate for thermal decomposition and as consistently yielding materials of electric power. Further plans are required to efficiently collect and store for processing without time delay.

Benefits of Biomass Based Power

While we are striving hard to switch to more sustainable modes of living, there arise lots of issues questioning the efficiency of our choice of green.  Despite all the issues they might have, they have more benefits than their petroleum counterpart. After all, petroleum is not going be here forever. So, this post will focus on the benefits of biomass based power, and why is it more suited as a sustainable alternative. Let us look at the distributed generation, because biomass is available in almost all places, and especially in rural areas, and more important, as gasification based power production can be done on small scales (as low as 20 kW), this process can be used for distributed generation of power as against the centralized power production method followed today. Also, biomass based power is well suited to remote villages with no access to grid but access to significant amounts of biomass Secondly, biomass gasification based power production can be done at small scales – as small as 20 kW – unlike other sources of power (say, nuclear) that require much larger scales. This will ideally suit small villages that have only a few households. Also, this whole process could be done in rural areas, where this could open a gateway of opportunities for rural population. Given that a 1 MW biomass based power generation could require biomass growth in over 150 hectares, the opportunities for rural employment are indeed significant. Thirdly, biomass power results in no new net GHG emissions as it is part of the carbon cycle. Unlike coal and others forms of fossil fuel which have been buried millions of years ago and burning them adds to carbon in the atmosphere, responsible biomass energy generation results in no new carbon emissions or pollution. Finally, the efficiency of the biomass power generation process to make use of mostly animal and crop wastes for energy is remarkable. Also, there is a large variety of feedstock which could be used for the process. Aside from these, they also significantly reduce methane in the atmosphere, which being able to be produced economically. I suppose these are enough reasons to switch to biomass power.

Biomass based power

Biomass is a valuable physical mass of biotic factors and ideally suited for the energy generation in different forms for the fulfillment of human demands over time. Even though deep ground fuel resources of biological origin satisfy it comprehensively, the way it is oxidized today on a time scale for energy production alarms the world by a phenomenon called “Global warming”. It forces us to scan for a suitable and sustainable alternative to fossilized biomass and the answer lies with surface dwelling, active biomass which is derived either from live or dead sources for power generation. Biomass can be subjected to power generation by combustion principle which is exactly followed for fossil sources and also is found to have a greater flexibility to generate power than conventional sources. Besides combustion, biomass is readily amenable for gasification where energy as power, heat and synthetic fuels can be derived. Biomass based power proves to be highly profitable under conditions where natural resources such as wood from forests, agricultural and animal sources etc are at abundance. India is a potential hub for this alternative route of power generation but currently holds a marginal fraction of 2650 MW out of its total installed capacity of 172000 MW. It utilizes bagasse co-generation system as its major option for biomass based power production with a capacity of 1411.53 MW achieved till June, 2010. It is important to note that biomass based power is multi-dimensionally advantageous as follows Rural economic upliftment, Suited for rural areas, Ability to have small kW scale power production, Distributed generation, Carbon neutral, Efficient utilization of renewable biological sources and accession of low cost resource.

Biomass conversion to natural gas – is this being followed anywhere?

I and my team might be working on an interesting project where the company is trying to move away from natural gas for its heating purposes and into the use of biomass for the same. The reason of course has to do with economics, with natural gas prices shooting through the roof past couple of years. While we are figuring out ways in which the company could use biomass directly for heating instead of natural gas, this process poses some problems owing to the specific needs of the client. I am hence wondering if the process of converting biomass to natural gas is being followed anywhere. I know that this is pretty much feasible, but not sure about the technology maturity and economics. If there is anyone who is aware of commercial conversions of biomass to natural gas, do let me know. You can include your response in the comment section or send a note to narsi [at] eai dot in. Thank you.

Biomass Gasification for the Environment and Economy

There are a whole lot of benefits from biomass gasification, both economy wise and ecology wise. Speaking of environmental benefits, gasification plants produce significantly lower quantities of air pollutants, which is really a good thing.  The process can also reduce the environmental impact of waste disposal because it can use waste products as feedstock, generating valuable products from materials that would otherwise be disposed as wastes. Gasification's byproducts are non-hazardous and are readily marketable and also use significantly less water than traditional coal-based power generation, and can be designed so they recycle their process water, discharging none into the surrounding environment. If that is not convincing, let us look at the economical benefits. Gasification can be used to turn lower-priced feedstocks into valuable products like electricity, substitute natural gas, fuels, chemicals, and fertilizers. For example, a chemical plant can gasify petcoke or high sulfur coal instead of using high-priced natural gas, thereby reducing its operating costs. While a gasification power plant is capital intensive (like any very large manufacturing plant), its operating costs are potentially lower than conventional processes or coal-fired plants because gasification plants are more efficient and require less back-end pollution control equipment. With continued research and development efforts and commercial operating experience, the cost of these units will continue to decrease. The process also offers wide fuel flexibility. A gasification plant can vary the mix of solid feedstocks, or run on gas or liquid feedstocks—giving it more freedom to adjust to the price and availability of its feedstocks. Many predict that coal-based power plants and other manufacturing facilities will be required to capture and store CO2, or participate in a carbon cap and trade market. In this scenario, gasification projects will have a cost advantage over conventional technologies.

Biomass Gasification in India to Generate Lakhs of Jobs

Emerging green economy in the country may see creation of nine lakh jobs in India by 2025, a top government official said.

"India could generate nine lakh jobs by 2025 in biomass gasification, of which three lakh would be in manufacturing of stoves and six lakh in areas such as processing into briquettes and pellets and the fuel supply chain," Ministry of Micro, Small and Medium Enterprises (MSME) Secretary Dinesh Rai said.

More from here.

I am not sure if biomass gasification alone could generate almost a million jobs. The secretary appears to have his numbers done for him all right, but I still wonder.

It will of course be good if it comes true. It was only yesterday that I met this gentleman whose company manufactures efficient burners for kerosene stoves and he was quite hopeful about the micro-gasifiers as well.

Let's see how it goes

Biomass Gasification Power Production – Bottlenecks and Barriers

Biomass gasification is a process where materials are transformed by thermal decomposition under partially oxygenated conditions to generate syn-gas for power generation. It seems to be a powerful technique where energy can be produced in a sustainable way along with valuable products such as green oil and biochar but it is multi step process where bottlenecks continuously arises at every step of the production pathway. The most commonly encountered limitations are batch to batch variation in  energy content, purification of the syngas, contaminants influence in the performance of the engines, ash and biochar disposals, toxic gas emissions and operational efficiency of the gas engines and mandatory modifications required to make the engines energy effective. In addition to these prime technical problems, others notable hindrances are insufficient capacity of the stakeholders and inadequate institutional and policy framework at the national, regional and local levels and limited access to financing and lack of interest on part of the state electricity boards (SEBs) in promoting biomass power generation etc. In India, conditions are further complicate by lack of working capital, limited interest in power projects, lack of effective regulatory framework and absence of effective information dissemination etc. In spite of the limitations, the technology continues to gain acceptance. Its potential to meet the energy demands on a flexible scale makes a robust move to outweigh the magnitude of limitations associated with it.

Cons of Gasifiers

The use of biomass gasification for power production is not new, but its use has been so far been limited and its contribution to the overall power production has so far been negligible in India. The producer gas derived from biomass gasification can be used for either producing power (by use in a gas engine) or can be used for thermal applications. With better technologies evolving for both gasifiers and gas engines, it can be expected that biomass gasification could start contributing a lot more to the overall power production in India. For starters, biomass gasifiers are reactors that heat biomass in a low-oxygen environment to produce a fuel gas called the producer gas. The gas produced from a gasifier can drive highly efficient devices such as gensets, turbines and fuel cells to generate electricity. A biomass gasification system consists primarily of a reactor or container into which fuel is fed along with a limited (less than stoichiometric, that required for complete combustion) supply of air. Heat for gasification is generated through partial combustion of the feed material. The resulting chemical breakdown of the fuel and internal reactions result in a combustible gas usually called producer gas. Though gasifiers are really special in their own way, they have their limitations. Gasification is a complex and sensitive process. There exists high level of disagreement about gasification among engineers, researchers, and manufacturers. Several manufacturers claim that their unit can be operated on all kinds of biomass. But it is a questionable fact as physical and chemical properties varies fuel to fuel. Gasifiers require atleast half an hour or more to start the process. Raw material is bulky and frequent refuelling is often required for continuous running of the system. Handling residues such as ash, tarry condensates is time consuming and dirty work. Driving with producer gas fueled vehicles requires much more and frequent attention than gasoline or diesel fueled vehlicles. Getting the producer gas is not difficult, but obtaining in the proper state is the challenging task. The physical and chemical properties of producer gas such as energy content, gas composition and impurities vary time to time. All the gasifiers have fairly strict requirements for fuel size, moisture and ash content. Inadequate fuel preparation is an important cause of technical problems with gasifiers. Gasifier is too often thought of as simple device that can generate a combustible gas from any biomass fuel. A hundred years of research has clearly shown that key to successful gasification is gasifier specifically designed for a particular type of fuel. Hence, biomass gasification technology requires hard work and tolerance. As I said, gasifiers are indeed special in their own way. I’d rather we just wait for the technology to advance in the future to go far beyond its limitations. After all, as I said then and I will again, petroleum is not here forever, and we need more sustainable feedstock and advanced technologies for processing.

Cool Solutions for Your Hot Problems – Getting Your Heating Costs Under Control

industrial heating boiler 1 Sustainable Industrial & Commercial Heating Solutions - A Critical Pain Point No, this blog post is not about those hot problems. It is about problems companies, especially in the manufacturing sector, face for their heating requirements! With the prices of furnace oil, diesel and LPG increasing alarmingly in the past few years, companies suddenly find their costs of their energy shooting up to unaffordable levels. Suddenly, using renewable and sustainable energy sources such as solar and biomass, and utilizing heat that was wasted earlier appear to be the way forward. I hence thought I’d provide an overview of renewable and sustainable options available for heating requirements in factories. The following are the sustainable heating avenues that are technically feasible today:

  • Solar Water Heater
  • Biomass
  • Waste Heat Recovery/CHP/Cogen
  • CST (concentrating solar thermal)
  • Energy efficiency heating equipment
  • Back pressure steam turbine
Solar Water Heaters Yes, we are talking about the simple and common solar water heaters. Could they provide a solution for industrial heating needs? The answer is Yes. Solar water heaters typically can provide temperatures up to only about 70OC, while many industries such as food and diary will require temperatures upwards of 150 deg C. This should however not be a deterrent as solar water heating can be used to preheat the water.  To the extent that solar water heaters can be used to replace furnace oil or diesel, proportionate cost savings can be derived. Taking the current prices of furnace oil, diesel, LPG or natural gas, even partial substitution of any of these fuels with solar heat makes significant economic sense. The capital cost involved in setting up this solar water heater facility can be recovered in about 2.5 years at the current prices of fossil fuels. Biomass based heating Let's consider a factory currently using about 10000 m3 of natural gas per day (or about 10,000 liters of furnace oil per day) for this discussion. Such a factory can save considerably by switching over to biomass from fossil fuels for its heating applications. The advantage with biomass based heating is that it is a firm source of energy and can technically replace the entire fossil fuel use for 24X7 operations. Biomass–based heating is a fairly old idea, but today, this can provide more bang for the buck using the gasifier technology which is a much more efficient way to provide heating than direct combustion. Essentially, combustion is not the best way to derive heat energy from biomass. Gasification, by first converting the biomass into an organic gas called the producer gas, makes the entire heating process far more efficient as it is easier to control and optimize producer gas for combustion than it is to optimize raw biomass. Using gasification also provides small amounts of charcoal as a by-product. Charcoal commands a good value in the marketplace. Today, a number of plants in India and overseas are seriously looking at using biomass for their boiler as well as their other heating and drying applications. The economics of biomass are fairly simple. At the current prices of biomass (Rs 4-5 per Kg), a 50 T per day biomass based gasification can displace about 10000 m3 of natural gas  or about 10,000 l of furnace oil. Natural gas costs about Rs 40 per m3 and furnace oil about Rs 42 per liter. Thus, biomass based heating would cost Rs 2.5 lacs per day vs Rs 4 lacs approx for either furnace oil or natural gas. This translates to a saving of Rs 1.5 lacs per day for such a facility or over Rs 5 crores per year!  The payback periods for these are in the range 2-3 years. Waste heat recovery / CHP / Cogen Utilization of waste heat has become one of the most sought after ways in the manufacturing sector today. With available technologies, it is today possible to convert both high temperature waste heat as well as low grade waste heat into useful heat or cooling. Of specific relevance here are technologies such as vapour absorption chilling, stirling engine and organic rankine cycle power generation mechanisms. While stirling engine is arguably not yet ready for large scale, reliable commercial use, vapour absorption chilling is a mature technology today, and organic rankine cycle is already a commercially available solution. VAM (vapour absorption) route will be especially useful for factories having significant cooling requirements, either in terms of air conditioning or for chilling/refrigeration. CHP/cogen is already quite prevalent in the sugar mills and distilleries in India. For those facilities that have large amounts of waste heat, CHP is a viable and financially rewarding option. Concentrating Solar Thermal Until a few years back concentrating solar heat was used predominantly for power generation – known as concentrating solar power (CSP). But today, using the same CSP technology as the base but with lesser sophistication, solutions are available that allow concentrating solar heat to generate steam up to 200OC, something that can be used in many process industries for most of their heating purposes. This has opened up the new domain of concentrating solar thermal (CST). CST is today a commercial solution and has already been adopted / implemented at many process industries in the country including diaries, food manufacturing units, large canteens and kitchens and the like. In most case, CST might not be able to replace conventional fuel use fully. It has however been estimated that it could replace up to 75% for many installations. That can be a tremendous saving for companies that are bearing the brunt of fast increasing furnace oil / LPG / diesel prices. Unlike solar water heaters, which is a highly mature technology, CST is still undergoing significant innovations, thus making it possible for companies to have high efficiency and high productivity technology installations in the near future. CST has been shown to have payback periods of less than 3 years in the installations that it is already operating in India. Energy Efficient Heating Equipment I recall a trip I made to a well-known hotel in Chennai where the chief engineer said said that by just replacing one old pump with a new, efficient one, they were able to reduce about 5% overall in electricity costs. This moral is true for many heating appliances and equipment too - be they boilers, furnaces, ovens or kilns. Of course, the decision is usually harder as the capital costs involved in changing over could be considerable, as these heating equipments will usually form the bulk of the cost of the overall heating system. Back-pressure Steam Turbine Back pressure steam turbines are not exactly for thermal efficiency or for reducing your heating costs, but I thought I’d include these here as they still provide a better bang for the buck from the heat generated. Back-pressure steam turbines essentially use the extra pressure and temperature that are inevitably present in the process steam to drive a small non-condensing turbine to generate power. The steam that leaves this back-pressure steam turbine goes on to do the useful work. As mentioned earlier, while it does not provide heat at a lower cost, it provides more value for the same amount of energy used for heating, by generating additional power from it. Summary There, you have it. Using one more of the above six avenues, factories that use significant amounts of heat can achieve significant cost savings while at the same time becoming far more “green” and environment friendly. Wish to know more on how your factory could be made more green through sustainable heating solutions? Send a note to me - Narasimhan Santhanam  ( narsi@eai.in  ).

Costs of feedstock for Biomass gasification

Biomass gasification utilizes renewable feed stocks for liberating the synthesis gas by thermal decomposition under high temperature conditions. Among the factors affecting the production protocol, cost economics play a critical role and is well pronounced in cases when the scale of operation is magnified. Entrepreneurs of gasification technology often make contracts with farmers or traders so as to ensure a price security and timely uninterrupted availability of their concerned feed commodity. In spite of the strategies, price fluctuations in gasification feed stocks have been witnessed, for instance cost of rice husk was at Rs: 600/tonne in 2009 but has steeply increased to Rs 1800/tonne by the end of 2010 and such an extreme volatility in market prices causes a concern to buyers and affect the final price of the power/unit produced by biomass gasification technology. Lack of price security has produced an unique trend in gasification where the venturers start their own farms for feed stock production which they claim that it can cut costs by two-third of the actual cost and seems to be working well in particular with dedicated energy crops. Gasification technology is well balanced economically as entrepreneurs have a scope to sell biochar by-product which fetches good market price to compensate for the cost procurement of the feedstock. Socio-economic and technical factors continuing to challenge the progression of gasification but the productivity makes it a superior choice that cannot be camouflaged.

Current Status of Biomass Gasification in India

India has initiated its power generation from renewable sources by several different principles namely gasification and combustion. Biomass gasification is carried out at different power capacity levels ranging from 25 kW to 2 MW and above. When a comparative analysis is made between combustion and gasification of biomass, the former technology is best operational under high capacity installations while the inverse is true for the gasification. This peculiar advantage seen in gasification to operate at smaller ranges makes the technology suitable for adoption in rural and by small entrepreneurs where power generation is required rather than efficiency. The technology even though best functions with high range installations of 2 MW, its utility is obstructed by the demand for a series for engines and India has less than 10 installations so far. Gasification technology is really ideal where resources are randomized and adoption of any other technology is tedious on a financial scale. Gasifiers are flexible to operate which makes the user to follow any technology depending on his requirements to a limited extent.

Decarbonizing India’s Energy Sector by Biomass and Biofuels


This post is a part of DIL Intelligence series from Energy Alternatives India (EAI), India's leading climate-tech consulting firm.

DIL stands for Decarbonization for India's Leaders and provides comprehensive market intelligence and updates to Indian corporate leaders on prominent decarbonization efforts across the Indian industrial ecosystem. DIL is provided by EAI's strategy consulting team. More about our consulting from here.


In India, 22% of the total energy supply is renewables, with biomass contributing 85%. Biomass use is shifting from traditional residential heating to power production. Biofuels represent less than 1% of transport fuels, with bioethanol at 3% of gasoline consumption. The biomass market is projected to reach INR 32,000 crore by FY2030-31. India produces 450-500 million tonnes of biomass annually, with a surplus of 230 MMT/year. Biomass-derived energy constitutes 32% of India’s primary energy use. The biomass pellet manufacturing capacity is 2.38 MMT, with 83,066 MT co-fired in 39 thermal power plants.

Reliance Industries Limited (RIL) is transitioning from fossil fuels to renewable energy, including biofuels, for its energy demand. This involves using bio-pathways to fix CO2 and recycling materials across value chains. RIL plans to set up around 100 Compressed Biogas (CBG) plants over the next five years, consuming over 5.5 million tonnes per annum of agricultural residue and organic waste. This initiative is projected to reduce nearly 2 million tonnes of carbon dioxide emissions annually. In essence, RIL’s decarbonization strategy involves renewable energy, biofuels, recycling, and CBG plants.

Thermax, an Indian energy and environment engineering company, is decarbonizing its manufacturing processes using biomass and biofuels. Its subsidiary, TOESL, installs biomass-fired plants and sells steam. Thermax’s solutions include the Atmospheric Fluidised Bed Combustion Boiler, capable of using various fuels including coal, lignite, rice husk, petcoke, spent coffee ground, washery rejects, low ash coal, paper sludge, roasted chaffs, DOB, bagasse, pith woodchips, coffee husks, mustard stalk, cotton stalk, and char. Thermax has secured an order worth over Rs 500 crore to set up five bio-CNG plants across India, with a capacity to produce 110 Tonnes Per Day of bio-CNG, utilizing local feedstock exceeding 1,000 TPD. This initiative contributes to the decarbonization of manufacturing processes.

The shift from fossil fuels to renewable energy sources is a key aspect of the company's strategies. This transition is driven by the need for cleaner energy sources and the potential economic benefits of renewable energy. Development of advanced biofuels like bioethanol, biodiesel, and biogas from sustainable feedstocks like algae and dedicated energy crops can further reduce reliance on fossil fuels and enhance energy security.

Looking ahead, the focus will be on enhancing the efficiency of biomass and biofuel technologies, developing second-generation bioconversion processes, and ensuring the sustainable sourcing of feedstocks. The potential of biomass and biofuels extends beyond just energy production. It opens up opportunities for waste management, rural development, and job creation, contributing to a circular economy. Companies like Reliance Industries and Thermax are pioneering this transition, demonstrating the viability and benefits of these renewable energy sources.

Emerging Feedstock for Biomass Power

Following my previous post on the industry perspectives on the various methods that have to be adopted for sustainable feedstock procurement (http://eai.in/blog/2011/12/industry-perspectives-and-strategies-for-effective-biomass-feedstock-procurement.html), today’s article showcases the various feedstock (emerging) that could be used as  a potential source for biomass-based power generation. As you might be well aware, the first generation feedstock such as sugars, starches from wheat, sorghum, sweet potato etc are not widely used for bioenergy production owing to the food-fuel conflicts. Similarly, even the second generation feedstock such as mustard are not being used in a big way for bioenergy production. These days, more focus is being thrown on the advanced feedstock such as the third-generation biofuels ( these seek to improve yields through improving the feedstocks themselves instead of the processes). These feedstocks include those sources that promise to generate greater than 500 gallons of oil per acre per year. Examples include palm oil and algae oil, rapeseed and jatropha oil, grasses (switchgrass, miscanthus), trees (willow), halophytes (saltwater plants). Provided are some details of the emerging biomass feedstock such as camelina, miscanthus and bamboo and their potential to perform as a bio-fuel. Miscanthus: Miscanthus, also known as Elephant grass can grow up to 3 meters high and it is native to tropical and sub-tropical regions of Africa and South Asia. Miscanthus is mentioned as a biofuel crop because of its relatively high dry matter yields across a range of environmental and soil conditions. The Miscanthus genotype most commonly recommended for biofuel production is a sterile hybrid (Miscanthus x giganteus) believed to be a M. sacchariflorus x M. sinensis hybrid. Miscanthus utilization in the biofuel industry is primarily for combustion in power plants – it has the desirable properties of low water and ash contents. Current research is focused on its potential as a biomass crop for direct combustion and for lignocellulosic conversion to ethanol. Giant miscanthus has been studied in the European Union and is now used commercially there for bedding, heat, and electricity generation. Most production currently occurs in England but also in Spain, Italy, Hungary, France, and Germany. Recently, Japan and China have taken renewed interest in this native species and started multiple research and commercialization projects. In the United States, research began at the University of Illinois at Urbana-Champaign in 2001 and has expanded rapidly to other U.S. universities. However there is currently little published information on giant miscanthus yields in the United States. Bamboo: Recently, bamboo has received increasing attention for producing biofuel because of its easy propagation, vigorous regeneration, fast growth, high productivity and quick maturity. Bamboo is an efficient user of land, and produces more biomass per unit area than most tree species. But the process of converting bamboo cellulose into liquid fuel is difficult to execute efficiently because of the extraordinary density of the plant.  However, new research from Mississippi State University hold clues for how scientists can learn to more easily break down bamboo, and thus more efficiently extract biofuels from all other cellulose sources using the bacteria from pandas’ waste. If the researchers are successful, the manufactured enzymes could be used in a new, much cheaper and more efficient process for converting bamboo and other woody plants into biofuels. Fuel properties and potential as a bio-fuel of different bamboo species:

Species Moisture content Density Ash content Energy content
% g/cm3 % MJ/Kg
B.pallida 44 0.61 1.91 18.63
B.tulda 37 0.65 1.92 18.61
D.asper 37 0.77 4.23 17.92
D.membranaceus 43 0.62 4.99 18.81
G.apus 35 0.76 2.00 18.14
Camelina Camelina, an oilseed, is a rotation crop for wheat that can be established on marginally productive land. It is an annual, short season plant. Biofuel from camelina is an ideal jet fuel substitute. Camelina has a number of advantages over its competitors, including using far less water, thus allowing it to be grown on marginal land, thereby not taking food acreage out of production. Furthermore camelina has a relatively short growing season of 80 to 100 days, requires no special equipment to harvest, and the silage remaining after processing can be fed to livestock and poultry, with the added side benefit of increasing their omega-3 production. Camelina is increasingly emerging as a prime biofuel source and thus attracts investment worldwide, as global demand for aviation fuel for passenger flights is now more than 40 billion gallons annually. In the earlier of this year, USDA announced two Biomass Crop Assistance Program (BCAP) project areas devoted to developing camelina as biofuel in several states, including Montana. USDA's Risk Management Agency (RMA) has also recently announced a new pilot program of insurance for camelina beginning with the 2012 crop year.

Future Feed-in-Tariff Trends for India – for Wind, Solar and Other Renewable Power Sources

It is an open secret that renewable power requires incentives - these usually are in the form of capital subsidies, tax incentives and most importantly, via feed in tariffs. It is a million dollar (make that Billion Dollar) question what the future of feed in tariffs will be for the mainstream renewable power sources. I picked up some resources on these. Wouldn't say they provide a peek into the future, but at least one of these try telling us how the government arrives at these numbers, so that will provide us with some clues.

How Biogas-based Power Generation is Picking up Pace in India

===========================================

 Most of us have come across the gobar gas – literally meaning gas from the cow. It is the same as what is called biogas. This is the gas that is released when bacteria feast on organic matter – typically human and animal feces – and release a gas that is about 50% methane. While biogas had predominantly been used earlier for heating purposes, its use for power production is also beginning to show a marked rise across the world, and in India too. How is power produced from biogas? The process is actually quite simple. Step 1 is generation of biogas. This is done typically using what are anaerobic called digesters. Animal (or human) waste is fed into the digester, where the microorganisms (called methanogenic bacteria) act upon it. Depending on the type of digester, it could take anywhere between 10 days to 15 days for the waste to have been "digested" by the bacteria and the release of biogas. The biogas thus produced can be used in IC engines specially devised for the use of biogas. These engines are similar in working principles to diesel engines and natural gas engines. These engines produce electricity from biogas. A bit of observation will lead us to easily understand why this concept will be of enormous interest to specific industry segments. Two segments stand out - industries that employ large numbers of animals and sewage treatment plants that treat human waste. Both these segments have started benefitting from this concept; as a result, we have a few STPs (sewage treatment plants) already generating power from the sludge generated (one of the STPs at Chennai, at a town called Nesapakkam, generates about 500 kW of power from the waste, and uses the power generated for all its electricity purposes). Some numbers will help understand the potential available for power generation from biogas. The cow population of India (about 225 million) alone generates about 800 million tons of wet dung which translates to about 150 million T of dry weight. 1 Kg of dry cow dung can generate about 1.2 kWh of electricity (it can generate the equivalent of about 4 kWh thermal). Thus, if all cow dung were converted to electricity, that would be 1.2*150*1000 million kWh = 180 TWh. India generated a total of 855 TWh in 2011-12. This implies that cow dung, if entirely converted to power, would have produced about 20% of total India's power! If the waste of other cattle and human waste were also taken into account, this could be about 30%. That is an awesome number. Of course, these data hide the actual difficulty in converting even a small portion of animal or human waste into electricity, owing to the infrastructural and social problems associated with these. All the same, waste -> biogas -> power is quite practical to a whole host of industries for whom such waste is available on premises. More information about waste to energy in general in the Indian context, is available from EAI's waste to energy resource section. Some of the following YouTube videos provide a more visual account of how to generate biogas from organic waste: Biogas from food waste - ARTI - http://www.youtube.com/watch?v=BGSl72xZHNk&feature=related Bio-gas from kitchen waste and bio mass - http://www.youtube.com/watch?v=uppVZGS7bYI&feature=related Biogas from Vegetarian Food Waste - http://www.youtube.com/watch?v=NZFrPZZIFTs&feature=related Biogas from Human Waste - http://www.youtube.com/watch?v=_m1nr2v5S8o And while on sewage, human waste and toilets, etc, a couple of interesting articles on things are emerging New toilet technology after 150 years of waste The seat of power - Better sewage treatment is the latest thing in clean energy Also check out: EAI Consulting for Bio-energy & Biofuels, Bioplastics & Other Biomass-based Value Added Products

How Punjab Will Benefit from All Its Agricultural Residue- A Case Study

Agricultural residues never go to waste. Not when they can be used for generating energy. In this context, the government of Punjab, India, plans to produce about 1,000 MW of green energy from livestock residues by 2015. When you think about it, this has huge economical and environmental benefits. In a region where large quantities of cattle manure become a major pollutant, this could be seen as an opportunity that could open a lot of doors. Aside livestock residues, the state also generates nearly 21 million tons of rice stalks and similar biomass plant wastes annually, which can all go into the production of green power. The state government is thus planning to make renewable resources as the source of their power to contribute 10% of its total energy production in the next five years. It is worthy to mention that Punjab already runs a biomethanation facility with a capacity of 1 MW, in a location close to Ludhiana. The facility uses methanogens (microbes that produce methane as a metabolic by-product) for the manufacture of methane gas. It currently uses 235 tons of cattle wastes to generate 18,000 kWh of electricity in addition to producing 45 tons of organic fertilizer every day. Also, the Punjab Energy Development Agency has developed 318 MW of green power projects, which includes the Ludhiana plant, till date. These projects comprise 37 MW of small hydro facilities, 28 MW of biomass power facilities, 250 MW of biomass co-generation facilities and 2 MW of solar projects. The agency also develops 132 MW of green power projects currently, which include 11 MW of hydropower, 100 MW of biomass co-generation and 20 MW of traditional biomass. If everything goes right and operational, the state will generate 700 MW of green power by 2012. That’s big! It is worthwhile to note that the planters are also getting an income of nearly RS. 4,000 per acre every year in the process of marketing agro wastes to biomass facilities.

Industry Perspectives and Strategies for Effective Biomass Feedstock Procurement

===========================================

Are you looking to get energy security for your company through reduction in the use of diesel, furnace oil, LPG and costly grid power? EAI can do a feasibility study for the use of solar PV & thermal, biomass for heat and power, waste heat recovery and energy efficiency to dramatically cut down fossil fuel use and reduce your energy bills. See EAI's SURE-FIRE offering for more.

 ===========================================

One of the most critical bottlenecks for biomass power plants is the supply chain bottlenecks that could result in non-availability of feedstock. A related problem is the volatility, or more precisely increase, in the feedstock price. Both these could render the project unviable. Highlighted in this article are some of the industrial perspectives in overcoming barriers for procuring a balanced feedstock supply. EAI’s research with industry experts suggest that there is no established biomass value chain that exists in India for the procurement and transportation of the biomass feedstock. Typically, the facility staffs  from a biomass gasification plant acquires biomass from several to dozens of small-scale biomass suppliers on a relatively informal, non contractual basis; although some have considered the use of aggregators, there is no data or proof available from the Indian biomass gasification companies that have engaged such a service as yet. The biomass procurement model that is typically followed in India is discussed below: Route #1 – Biomass Producer -->Transport Contractor --> Biomass Collection Centres (BCC’s) --> Power Producers The biomass producer i.e. the farmers/mill owners hands over the feedstock to a transport contractor who in turn delivers the feedstock to the biomass consumers or BCC’s. The BCC’s (managed by the biomass consumer) pay the farmers and the power producers collect the feedstock from these collection centres as and when required. At some instances, the farmers deliver the feedstock in the power producer’s facility and get directly paid for it. Route #2 - Biomass Producers --> Waste Processing Mills -->Biomass Power Producers For feedstock where further processing is required, the farmers/mill owners deposit the feedstock in waste processing mills. From the waste processing mills through a transport contractor the feedstock is deposited in the BCC’s or directly in the power producer’s facility. In some cases, especially in briquetting, the processing is done in the collection centres itself where a mobile briquetter is taken and the briquettes that are processed are directly delivered to the facility or collected by the power producers. Key Strategies to be Followed for Effective Biomass Feedstock Procurement EAI’s interactions with the industry reveal that the following strategies have to be adopted   in order to bring both the availability and price of biomass under control:
  • Security should be addressed by obtaining a written formal supply agreement with a reputable, local supplier. A five-year signed supply agreement with pricing and minimum volumes can go a long way in helping to secure necessary financing. A bioenergy project that is totally reliant on only one source of feedstock will be at risk, so two supply contracts are even better. This will also allow one to negotiate a better feedstock price, as the supplier will benefit from a long-term relationship and a guaranteed market. An interested lender needs to know that both the feedstock supplier and bioenergy processor are committed to the project.
  • It can be beneficial to hire an independent professional to verify one’s biomass supply projections and double-check that the feedstock supply is sustainable over the long term
  • Backward integration and own captive biomass source (one company, Orient Green Power, is even trying out a novel technique of going for energy plantations on their own wind farms)
  • According to the Washington based biomass supply company ‘Powerstock’, for a well-managed supply, an inclusive definition of biomass is needed. The company is also taking efforts to educate the public on the value of well-managed, productive forests.
  • The bottom line of feedstock security is composed of several aspects: grower relations, harvesting, marketing, equipment utilization, proprietary techniques and agricultural economics. Hence it's important to manage the entire process from seed to market.
  • The supply sector needs to make the transition from a residues-based approach to an integrated, dedicated feedstock supply system using energy crops, plus residues.

Potential for Biomass Power in India

Biomass based power generation is a choice of reality under the geographical regions where a sustainability exists in the flow of biologically raw materials for the production of power and India is one of the most notable universal giants for the production of biomass based power which can be best understood from the estimates of its biomass availability and the power produced from it. India has biomass production of 546 million tonnes per year from the agricultural sources alone to generate electricity at a capacity of 17,982 MW and its overall production of power from renewable sources stands at 34961 MWe in 2010.A calculated annual growth rate for the next decade realistically and optimistically is above 42,000 MWe and 48640 MWe respectively. The development of biomass based power is further enhanced by the Government regulatory policies by declaring duty exemptions’, tax breaks and financial incentives etc. The cost of producing electricity from biomass is affordable at Rs: 2.25-3.25 / kWh. In spite of all these attempts biomass based power generation is at its infant stage because of hindering factors such as feedstock availability, transportation, price volatility etc. India to emerge as a role model must utilize its renewable energy sources to a large extent, develop dedicated energy crops, establish end user market for co-products such as charcoal, biochar, activated carbon, and implement energy efficient technology for economically feasible power generation on a massive scale.

Mitsui, a leading Japanese conglomerate, has recently invested ₹4.1 million in Punjab Renewable Energy Systems Pvt. Ltd. (PRESPL), a company focused on collecting agricultural residues and converting them into biomass briquettes and pellets. This investment underscores the growing potential of the Indian biomass sector, which is expected to witness significant growth in the coming years.

The Indian biomass market is estimated to be valued at around ₹50,000 crore and is projected to reach ₹1,00,000 crore by 2025, driven by factors such as the Increasing demand for renewable energy, Growing awareness of environmental concerns, and  Supportive government policies.

The Indian biomass sector is also witnessing a surge in international collaborations, with several prominent companies entering the market through partnerships and alliances. For instance,  Aramco, a prominent oil and gas company, joins forces with ReNew Power, India's largest renewable energy company, to explore opportunities in developing and deploying low-carbon technologies, including biomass-based power solutions. This collaboration signifies the growing interest of leading energy giants in exploring cleaner alternatives. 

Additionally, Danish Biogas's collaboration with the Maharashtra Energy Development Agency (MEDA) brings together expertise in advanced biogas technologies with experience in promoting renewable energy and rural development in Maharashtra. This partnership contributes to a more sustainable waste management system through biogas generation..

These strategic partnerships are just a glimpse into the exciting developments propelling the Indian biomass sector forward. The government is also playing a crucial role in accelerating its growth through supportive initiatives like subsidies for setting up biomass power plants and briquette/pellet production units, promoting dedicated energy crops and efficient residue collection systems, and providing tax benefits for biomass projects. Investments in research and development are also being made to improve conversion technologies, optimize feedstock utilization, and develop cost-effective biomass solutions.

Navigating this complex ecosystem requires a comprehensive understanding of the key players involved. The Indian biomass value chain comprises various stakeholders, including biomass producers like farmers and forestry companies, collectors and aggregators responsible for managing feedstock collection and storage, processing and conversion companies that transform biomass into usable forms, original equipment manufacturers (OEMs) who create machinery for the sector, suppliers providing essential goods and services, power plants and industries utilizing biomass-based fuels, and government agencies responsible for regulation and promotion.

Beyond the core value chain, the adjacent value chain plays a crucial role in supporting the sector's growth. This includes financial institutions offering loans and investments for biomass projects, research institutions and universities engaged in R&D advancements, and non-governmental organizations (NGOs) promoting sustainable practices and advocating for policy changes.

Indigenization remains moderate to low currently, with reliance on imported technologies and equipment. However, government initiatives and rising demand are expected to gradually increase domestic capabilities in the coming years.

Primary Routes for Power from Biomass

The three primary routes for biomass to power are: Combustion, Gasification and Anaerobic Digestion. Combustion is easy to understand – instead of using coal or other fossil fuel, use biomass to produce steam that runs a turbine. Combustion of biomass for power could either be in the form of co-firing (when it is burned along with coal) or pure play biomass based combustion. In the case of gasification, the biomass is first gasified and this gas turn produces power in a gas engine. Anaerobic digestion is usually applied to biomass that typically have a high amount of water in them (anaerobic digestion is most used for treating organic waste such as kitchen waste and sewage waste into energy). Under this route, microorganisms act upon the organic matter present in the biomass under anaerobic (absence of air) and convert it into biogas. An emerging route for biomass based power is pyrolysis. In this, the biomass is rapidly heated to 450 - 600 °C in absence of air, and results in a bio-oil called the pyrolysis oil, which can in turn be used for firing the boilers. Typically, 50 - 75 % (by weight) of the feedstock is converted into pyrolysis oil. Pyrolysis as a method for power production is not well established currently in India or elsewhere in the world. Typically pyrolysis plants work well beyond 2 MW scale, while gasification plants work well until 2 MW scale, at the current technological progress. Thus, it can be said that pyrolysis takes off where gasification ends. Also check out: EAI Consulting for Bio-energy & Biofuels, Bioplastics & Other Biomass-based Value Added Products

Prominent biomass feedstock for gasification

Biomass for power generation by combustion or gasification is normally variable in its chemical composition of electron rich reactants, ash content, moisture, sulphur and nitrogen content etc. As a result, selection of the most convenient feedstock is an issue of debate. The degree and diversity of contaminants strongly influence the production and purification of synthesis gas in gasification while they tend to have a minimum effect in the combustion process. Independant of these disturbances virtually any raw material applied in power generation process should be a matter with potentials. In India, a vast array of feed stocks are utilized for power generation but the most wide ones are farm and mill wastes, woody trees, energy plantations and other green manure crops. Preference is made on the basis of availability, cost, bulkiness of the material, pre-processing, storage etc. Biomass used in India yields varying level of energy but it is also the gas engine and generators whose efficiency equivalently determine power generation.

REC Price Band Revised

The Central Electricity Regulatory Commission(CERC) has announced the floor and forbearance prices to be used for solar/non-solar projects from the FY 2012-13 upto 2016-17. The prices set are shown in the table below

Non Solar (Rs.) Solar (Rs.)
Prices (2012-2017) Current % Reduction Prices (2012-2017) Current % Reduction
Forbearance Price 3300 3900 15.38 13400 17000 21.18
Floor Price 1500 1500 0.00 9300 12000 22.50
Background Earlier, the CERC had proposed a few changes (refer table below) to be made to the REC prices and invited comments/suggestions on the same.
Non Solar (Rs.) Solar (Rs.)
Proposed Current % Reduction Proposed Current % Reduction
Forbearance Price 3480 3900 10.77 13690 17000 19.47
Floor Price 1400 1500 6.67 9880 12000 17.67
  The final prices to be enforced from April 2012 were arrived at after considering the comments/views of stakeholders and participants at the public hearing on the proposed floor and forbearance prices. As can be seen, the final prices decided upon are considerably lower than the earlier proposed prices. Analysis Financial feasibility studies of power plants under the REC mechanism almost always consider the floor price for calculating returns. With this in mind, the evaluation of REC for the primary renewable energy generation systems looks quite healthy.
  • Non-solar – the floor price remains unchanged. Thus biomass/wind generators are expected to get the same minium revenue as they have been getting earlier.
  • Solar – the floor price has seen a cut of about 23% from current levels. Although this might seem drastic, it is not likely to have a significant impact on solar power projects (refer section below).
  APPC – Non preferential tariff and REC CERC stipulates that for a project to be eligible under the REC mechanism, the power producer has to sign a PPA with the state utilities at a price equal to the APPC price. The APPC price for a state for a particular time period is determined by the State Electricity Regulatory Commissions(SERC). Looking at the current APPC prices in various states, a combination of REC and a PPA signed at APPC rates seems comparable with the preferential PPAs signed with the state utilities. For example,  let us consider a solar PV plant to be setup in Tamil Nadu where the APPC price for 2011-12 is Rs. 3.38/kWh. Under REC regulations, if a RE developer were to get the floor price for the solar REC, the income for the solar PV plant would be Rs. 12.68 /kWh (Rs. 3.38 + Rs.9.3). Another case is Rajasthan, which has a very high potential for solar PV – where the income would be Rs. 11.9 /kWh. In comparison, under the phase 1 (batch 1) of JNNSM, the average price settled on through the reverse bidding process was  about Rs. 12.5 per kWh. As can be seen, these prices are comparable to tariff set through reverse bidding under batch 1 of the JNNSM scheme. Prices can only go higher APPC prices are set based on the cost of power generation from fossil fuel based power plants. It is highly likely that this price would increase in the future due to the increase in fossil fuel prices and scarcity of supply. This ensures that the APPC prices would continue to increase for the foreseeable future, thus ensuring higher year on year returns under the REC mechanism provided the PPA signed with the state utilities has provisions for purchase at floating APPC prices rather than fixed price. The table below gives a comparison between preferential tariff (reverse bidding under JNNSM) and REC mechanism for a plant in Tamil Nadu. The following assumptions were made for the sake of calculations
  • Average bid price under phase 1 batch 2 of JNNSM could be around Rs. 12.5 /kWh(on the higher side)
  • APPC prices could rise by 15% annually (base price used is that of Tamil Nadu) - reasons for this were mentioned earlier.
  • REC price after 2016-17 period (i.e. from FY 2017-18 onwards) is reduced by 25%
 
Year 2012 2013 2014 2015 2016 2017 2018 2019 2020 2021
JNNSM Tariff (average) (Rs. per kWh) 12.5 12.5 12.5 12.5 12.5 12.5 12.5 12.5 12.5 12.5
APPC (Rs. per kWh) 3.38 3.89 4.38 5.04 5.38 6.19 6.38 7.34 7.38 8.49
REC (Rs. per kWh) 9.30 9.30 9.30 9.30 9.30 6.98 6.98 6.98 6.98 6.98
Total (Rs. per kWh) 12.68 13.19 13.68 14.34 14.68 13.16 13.36 14.31 14.36 15.46
REC mechanism's Incremental revenue over PPA(Rs. per kWh) 0.18 0.69 1.18 1.84 2.18 0.66 0.86 1.81 1.86 2.96

Table: REC vs preferential PPA for 10 years post 2012

As can be seen from the above table, the REC mechanism is quite comparable, if not better when compared to the assured tariff provided by NVVN over 10 years of operation of the solar powerplant. Overall, the REC mechanism can clearly drive the solar market, provided the Renewable Purchase Obligation (RPO) is strictly enforced by the various SERCs.

The REC trading for the month of November concluded yesterday. Figures reveal that the trading has increased significantly both in volume of RECs traded as well as the price. In total 105,527 RECs were sold. Keeping with the trend of previous months, IEX had a higher share of the market with 96,154 (90%) RECs traded while PXIL saw trading of 9,373 (10%) certificates. The large volumes of trading indicate that the obligated entities are trying to fulfil their RPO as soon as possible as REC prices are showing an upward trend. The price of REC varied between the two exchanges - IEX and PXIL. Non-solar RECs closed with a price of Rs. 2,900 at IEX while the RECs sold at Rs. 2,800 at the PXIL. At the IEX, the prices have seen a 7% rise over those paid last month where the trading price was Rs. 2,700 per REC.

Interestingly, there are 43 buy bids for solar REC; this suggests that the solar REC market is gathering steam. This growing interest suggests that solar projects being planned based on REC may soon be bankable and we could see a trend in developers going for the REC mechanism during the interm period between now and the second phase of the National Solar Mission. Solar developers have another reason to rejoice as well as maintain a shrewd view on the Solar REC market. This month saw the accreditation of the first Solar project under the REC mechanims - an 8.5 MW solar project located at Jalgaon, Maharasthra developed by Jain Irrigation Systems. This project's viability has to be closely followed over the coming trading sessions as the REC certificates generated from the project slowly start coming up for sale. In total there are about 244 projects registered under REC with an aggregated capacity of 1551.92 MW (this excludes the lone solar project that recently got accredited). Conclusion The REC market continues to impress with higher sale prices and volumes. The REC prices are expected to rise over the coming months given the fact that there only 4 months left for RPO compliance. However, the price as such is expected to rise only gradually and not at the high rates seen over the year. The registration of a solar project under the REC mechanism might open the flood gates for more solar projects depending on the performance of the solar RECS. This could lead to a pradigm shift in the solar project development in India, which up until now has looked up to the state/central solar policies as the only source for project viability thereby reducing the cost of solar power in India and accelerating the road to grid parity.   Also check out: EAI Consulting for Bio-energy & Biofuels, Bioplastics & Other Biomass-based Value Added Products

REC Trading – September 2011

The REC trading for the month of September concluded recently. Trading figures reveal that the trading has increased significantly both in volume of RECs traded as well as the price. In total 46,362 RECs were sold. Keeping with the trend of previous months, IEX had a higher share of the market with 41,385 (89%) RECs traded while PXIL saw trading of 4,977 (11%) certificates. The large volumes of trading indicate that the obligated entities are trying to fulfil their RPO as soon as possible as REC prices are showing an upward trend. The most encouraging part of the trading was the price paid for each certificate. The price of REC grew to Rs. 2300 from Rs. 1800 last month.

Interestingly, there are 7 buy bids for solar REC; up from the lone buy bid last month, although this is promising, it highlights a serious issue. As with the previous months, there are no solar RECs available as no projects are registered under REC. This is a worrying trend and is going to put immense strain on the obligated entities to fulfil their solar RPO. The reasons for lack of solar projects registered under REC could include

  • Higher payback period for solar projects
  • REC prices guaranteed only up to 2016-17
  • A combination of the above two greatly reduces the bankability of solar projects
Conclusion The increase in REC trade volumes and price is very encouraging. It shows that the mechanism is a viable revenue route for developers who have not signed any preferential PPA. The demand for REC certificates is bound to keep increasing as more and more obligated entities try to fulfil their RPO in the short time span available. This is scheduled to push the REC price even further which in turn could lead to REC prices hitting their forebearance highs in the coming months. Finally more effort needs to be put in to ensure that there is sufficient supply of solar RECs in the market.

This session had two speakers – Mr. Srinivas Chakravarthy, Country Head – Industry Services, TUV Rheinland(India) and Ms. S. Vasanthi, Director – Technology and Marketing at Websol Energy Systems. Mr. Chakravarthy of TUV Rheinland spoke about the module certification process in general and TUV Rheinland in particular. He started off by explaining the various environmental influences during the long term operation of PV modules. This includes solar radiation, temperature, mechanical stress due to factors like wind, atmosphere,etc. He explained the different standards for Performance, safety and qualification. Subsequently, he described the different tests conducted for the IEC or other certification. This includes subjecting the modules to high level of different types of stresses(temperature, sunlight, handling, partial shading, wind, UV rays,etc).He concluded by talking about the various services offered by TUV Rheinland and also about the new test facility in Bangalore. The last speaker of the session was Ms. S. Vasanthi. Her topic was “ Improvement in Crystalline Si PV Modules Through Quality Control and Innovation in Manufacturing Processes”. She explained the various steps in the solar PV cell and module manufacturing process. She described the various quality control measures and some of the common defects like browning of cells. The effect of each of the raw material for a module(metallisation paste, ribbon, flux, encapsulant,etc) on the final quality of the PV module was also discussed. That concluded the 3rd edition of the Renewtech India conference. The 4th Renewtech India conference is scheduled for 16-18 February 2012 at the same venue – Bombay Exhibition Centre, Goregoan, Mumbai.

Rice husk used for power in one of India’s poorest states- A case Study

Whoever thought rice husk can generate power needs a medal! Considering how much rice husks go to waste in a country where rice is the staple food, it is comforting to know fossil fuels are not our only resort for power production. Thanks to Manoj Shinha, a renewable energy entrepreneur pioneered using discarded rice husks as biomass to provide energy to Bihar, one of India’s poorest states. Mr. Shinha along with his colleagues Gaynesh Pandey, Ratnesh Yadav and Charles W. Ransler developed Husk Power Systems to address the situation of poverty in their home state of Bihar. Many villages in India live off the grid in the darkness, this new advancement means that they need not depend on grid for electricity, rather generate their own clean, affordable electricity.The company generates and sells electricity for a price that is less than half of what the villagers pay for kerosene. This was possible because the whole concept is focused on research and development investment to simplify energy production and transmission, such as using bamboo instead of cement posts to install power lines.And, since communities no longer use kerosene, wood or dung for electricity, this way of electricity generation lowers the environmental and health hazards. In addition, rice husk ash, a byproduct of the gasification process, can be used for concrete production thus reducing the amount of high-carbon Portland restless leg syndrome cement.On average, a single power plant serves 400 houses, replacing 42,000 liters of kerosene and 18,000 liters of diesel yearly. As of August 2010, H.P.S. has sequestered 50,000 tons of carbon dioxide. Currently, they have installed over 60 mini-power plants that are 100 percent biomass-based which supply power to over 25,000 households in more than 250 villages.With the market opportunity in mind, they aim to expand their business to bring clean electricity to Indian villages by installing 2,000 new plants by 2014 beyond Bihar.

Tamil Nadu’s Biomass Power Plans – Energy Plantations is the Answer?

Biomass is one of the renewable energy domains in which Tamil Nadu could have significant potential for progress in future. Estimates suggest only about 10% of the potential has so far been utilized. Of course, the lack of a robust supply chain that make create supply and price security is a problem as much in Tamil Nadu as it is in the rest of the country. Some inputs and updates for biomass power in Tamil Nadu are provided below.

  • Potential for Biomass based power in Tamil Nadu is 1589.9 MW (1160 MW based on agricultural waste and 429.9 MW from forest and wasteland cultivation).
  • 22 biomass power plants with total installed capacity of 169 MW are in operation.
  • Ten biomass power plants with totaling to 120 MW, with over 80% plant load factor, have faced temporary shut downs owing to unviable tariff rates and increasing feedstock cost.
  • Biomass power producers association has approached Tamil Nadu Electricity Regulatory Commission (TNERC) with a request to revise the tariff and offer higher annual tariff escalation. The viable rate for operating biomass power plants in years to come would run beyond Rs 6.50/kWh, but the current tariff of Rs 4.5/kWh is in no way adequate to sustain the projects in the long run.
  • Tamil Nadu Energy Development Agency (TEDA), along with Tamil Nadu Biomass Power Producers Association, has been actively involved in promoting large scale energy plantations in marginal / waste land in the state with high potential crops.
  • The Tamil Nadu Biomass Power Producers Association suggests that energy plantation would not only serve to provide cheap and continuous feedstock supply for power plants, but it would also improve the quality of life of the rural population. Estimates suggest that a 10 mw biomass power plant can ensure livelihood of over 2,000 marginalised families. They can be employed in collection, transportation, cutting, chipping of biomass and cultivation of wasteland with energy plants like Juliflora, Bheema Bamboo etc.
So, it looks like Tamil Nadu is betting significantly on energy plantations for a viable biomass power sector. Let’s hope they have got it right. Also check out: EAI Consulting for Bio-energy & Biofuels, Bioplastics & Other Biomass-based Value Added Products

The man propelling the bio-energy movement in India – PRESPL

Welcoming Lt Col Monish Ahuja to CLIMAFIX SUMMIT 2022 - the 1st summit for Indian climate tech startups. I'm sure you have heard the saying, "Water, water everywhere, not a drop to drink" That applies quite well to the Indian agricultural residues as well. Hundreds of millions of tons of agro waste around the country, but very little available for the industries to use. And worse, a good portion gets burnt on the fields because the farmers do not know what to do with them. So where's the challenge? What is broken in this system? To a significant extent, logistics, or rather the lack of it. Securing and transporting millions of tons of agricultural waste from hundreds of thousands of farmers and transporting it reliably to end users is not rocket science. But it is systems science. Discipline science. Or patience science, if that term is more endearing to you. In EAI's decade long work in the bio-energy sector during which we consulted for dozens of clients including the likes of GSK (#Horlicks division, now part of Unilever), we have seen how unorganized the agro-waste supply has been, except for bagasse coming straight from large sugar mills and to a lesser extent saw dust from plywood factories. It is a complex challenge of logistics, societal & local traditions, and of course the omnipresent politics. The sector needed someone who could wade through all these, build an efficient system and evolve an organized biomass supply chain. Enter Lt Col Monish Ahuja. Army discipline, Systems thinking. Business acumen. These characteristics have helped him build Punjab Renewable Energy Systems Private Limited (PRESPL) into a force to reckon with countrywide in industrial biomass supply. PRESPL is today is one of the few organized players that has the ability to provide industrial decarbonization on scale through biomass, supplying thousands of tons of agro-waste based biomass every day to industries. I remember sitting with him in his office in Navi Mumbai a few years back when he patiently took me through the process by which he was building an effective front-end logistics system while also putting together a scalable digital back-end system. While coming out from the meeting, I thought - finally, here's someone who appears to be just what the doctor ordered for India's bio-energy sector. Since then, his company has - not surprisingly - grown and grown. Hats off to Monish, and we are proud to have him as one of the experts who will share his insights at the CLIMAFIX SUMMIT 2022, India's first climate startup summit, Nov 25 & 26, Chennai, organized by the Climate Startup Intelligence division CLIMAFIX of EAI (Energy Alternatives India) & Energy Consortium - IIT Madras Welcome Monish, and here's hoping you inspire more of your breed - and soon.

VC / PE Perspectives and Opinions on Biomass Power

Indian VCs have not really done a good amount of investing in cleantech. Cleantech perhaps  is not really a VC game as it is more of an engineering related discplie that does not offer the types of scalabilitiees that VCs desire or the exit periods. VCs also do not understand cleantech well enough to take calls. Many cleantech deals, especially in the power segment, are PPA based, with limited upsides, not typical VC games. Many cleantech and renewable energy startups require capital that is much higher than what VCs can typically offer to invest. Predictions for Cleantech VC in 2011 - Kachan & Co.'s Dallas Kachan looks at what 2011 will have in store for cleantech (http://alwayson.goingon.com/node/66783 ) Sustained worldwide venture capital investment will continue to cede importance to corporate and non-institutional capital. A return to early stage venture investments - predict a return to early stage venture capital investing in cleantech in 2011. Energy efficiency emerges as the clear rock star of cleantech. Biofuel investment could reach former highs. Recycling and mining will attract more investment. Natural gas emerges to threaten solar and wind for utility renewable power generation. China becomes the most important market for cleantech: if you're not selling in China, you won't matter. There is a significant amount of interest among PEs for investments in both traditional and renewable energy. PEs – not surprisingly – are not very keen on risky technology bets in renewable energy, but are OK with business model risks. Some of the PEs (such as IFC, ADB etc) are willing to take fairly long-term views (with over 10 year horizon). Investment sweet spot ( in terms of the quantum) varies from fund to fund, but obviously for most of the blue-chip, it is upwards of $50 million. PEs are well aware of the regulatory and societal bottlenecks that could arise in large-scale energy sector investing (especially for coal-based and large-hydro based sectors). Many PEs are clear that they wish to invest in businesses that can stand on their own revenues (even if takes a while) and are not keen on business plans that rely on getting bought out. Most every PE acknowledged that while they might not like coal, it is here to stay as the largest contributor to power for the foreseeable future. PE arms of organizations such as IFC and ADB, while not shutting out the option of investing in coal-based or natural gas based power plants, have a mandate to decrease their exposures to these “non-green” sectors. What a PE can bring to the table - Many private equity funds have been able to provide not just the financial support required but also strategic support and value-add for the firm’s growth. Disconnect in Valuation expectations - one of the issues faced by PE players while investing in cleantech companies is the disconnect in valuation expectations between the entrepreneur and investor with the buoyant public markets resulting in an increasing buoyancy in expectations! PEs feel that entrepreneurs should take a longer term view while setting their valuation expectations. Currently, 80% of infrastructure projects, and 46% of power projects, are funded by the banking system. So, PEs constitute only a small share of the infrastructure projects. While private equity folks could like IRRs of about 25%, power and infrastructure IRRs is only about 12%. Some private equity companies might wish to play a consolidator’s role as well where they consolidate a diverse portfolio of (say) energy companies such that they win even if 7/10 companies do well enough. Investors such as IFC have specialists/experts in every project to take care of social and environmental aspects. Private equity funds are interested in the macro factors (demand supply gap in electricity et al) as well strategic micro factors. One of the factors that seem to interest PEs is the method for companies to go diversified on green power that is having assets in wind, small hydro, biomass etc together, instead of betting just on one thing alone.

Why Biomass for Power Generation?

Biomass has been used as a source of energy right since mankind started its existence; In fact, one of the predominant energy sources today is biomass. Biomass as a source for power production is not entirely new either. Biomass has been used, in the place of coal, for steam generation at power plants, though in a limited way. Indeed, currently, the predominant method used for producing power using biomass still is the combustion route, At the same time, other processes, such as biomass gasification, which can work at much smaller scales and use the biomass more efficiently are emerging. The newer processes especially biomass gasification based power production, is relevant today especially in the Indian context mainly because of its potential to provide distributed power at rural level, especially for small remote villages that have good access to biomass but no access to grid power, and which require only small scale power production. Biomass based power is also relevant in the context of climate change and global warming as biomass based power production is net carbon neutral. The contribution of bioenergy to the total primary energy consumption in India is over 27% (Source: FAO). This is indeed the case for many other countries, because biomass is used in a significant way in rural areas in many countries. However, the contribution of biomass to power production is much smaller than this percentage – currently, biomass comprises only about 2650 MW of installed capacity, out of a total of 172000 MW of total electricity installed capacity in the country. Besides, biomass power has the following benefits- distributed generation, baseload power, ability to have small, kW scale power production, suited for rural areas and ideal for rural economic upliftment. I believe these are enough to justify why biomass is best suited for power production. Check out: EAI Consulting for Bio-energy & Biofuels, Bioplastics & Other Biomass-based Value Added Products

A 900 MW Power Plant Running on Biomass? It Could be a Reality in Five Years!

I thought I was never going to see the day when a large power plant would run entirely on biomass. You can understand my pessimism when you are told that a MW of powerplant will require about 8000 T of biomass every year. A 300 MW power plant will hence require an awful 2.5 million T of biomass every year. That's a heck of a lot of, well, anything. Well, there are some courageous folks around the world. Drax in the UK, for one. They are building 3x300 MW furnaces on biomass, and are arranging for a 8 million T biomass supply from around the world. (By comparison, India's total biomass based power production - outside of bagasse power - is only about 1500 MW. So the Drax project alone would be about 60% of total Indian biomass installed capacity!) While I am certainly overawed, good news, I must say. If they can operate it sustainably for a few years, biomass power would have definitely reached a milestone. Will be really keen to know how they plan to manage the supply chain. This is what the news report has to say "The vast majority of the biomass will come from North America, but there will also be locally sourced supplies of willow and elephant grass to power the furnaces. "

A Case Study of Clenergen and Yuken’s Gasification Biomass Project

Yuken India Limited, set up in 1976 under a technical and financial collaboration with Yuken Kogyo Company Limited, Japan, is a manufacturer of oil hydraulic equipment. Yuken has achieved one of the fastest growth rates in the Indian oil hydraulics industry, in the last 29 years. Clenergen India Private Limited, a wholly owned subsidiary of Clenergen Corporation, plans to enter into a minimum 15 years Power Purchase Agreement (PPA) with Yuken to supply up to 2.5MW/h, with the rest of the electricity generated being completely sold out to the National Grid System. The biomass power plants with a capacity of 4 MW/h will be installed and begin operation within 10 months upon signing of the PPA. Clenergen India plans to lease up to 800 acres of non arable land near the manufacturing site in order to grow a high yielding species of bamboo as a source of biomass for the gasification power plant. The bamboo produced is asexual, non-invasive, non-flowering plant with a lifespan of up to 50 years and above all, is a product of tissue culture. This is advancement in the sector of renewable energy, in that the cost savings created from the cultivation of biomass feedstock will allow the supply of electricity at a price lower than the current market prices and will also help to extend the industries’ vertical market penetration into these market sectors. This is certainly moving forward. With ever increasing fossil fuel prices, this is the ideal way to deal with the growing needs and the economy.   Also check out: EAI Consulting for Bio-energy & Biofuels, Bioplastics & Other Biomass-based Value Added Products

Agricultural biomass availability in India for power generation

India is primarily an agricultural nation with an extensive cultivation of different types of crops including cereal, pulses, oilseeds, fibre crops, spices and plantation crops. With the cultivation of these crops, availability of residual biomass after economic harvest makes power generation in a sustainable way. These raw materials are normally available in variable quantities depending on the acreage of cultivation, mass of residue part available. The total biomass is 511,041 kT/Yr for power generation. Among them, rice, wheat and cotton constitute a major portion with 160,000,111,000 and 21,000 kT/Yr to generate power of 5000, 3300 and 3500 MW respectively. The total power generation capacity is 17,400 MW. Besides these crops, maize, jowar, bajra, coconut, groundnut, banana, cassava and mustard are also potent generators of biomass for power to an appreciable extent. It is evident from the information stated above that the agricultural resources serve as excellent candidates for the power generation either by combustion or gasification. However it is important to note that these materials are variables by biochemical composition and moisture. So, standardization is mandatory by defining limits to make them appropriate for thermal decomposition and as consistently yielding materials of electric power. Further plans are required to efficiently collect and store for processing without time delay.

Benefits of Biomass Based Power

While we are striving hard to switch to more sustainable modes of living, there arise lots of issues questioning the efficiency of our choice of green.  Despite all the issues they might have, they have more benefits than their petroleum counterpart. After all, petroleum is not going be here forever. So, this post will focus on the benefits of biomass based power, and why is it more suited as a sustainable alternative. Let us look at the distributed generation, because biomass is available in almost all places, and especially in rural areas, and more important, as gasification based power production can be done on small scales (as low as 20 kW), this process can be used for distributed generation of power as against the centralized power production method followed today. Also, biomass based power is well suited to remote villages with no access to grid but access to significant amounts of biomass Secondly, biomass gasification based power production can be done at small scales – as small as 20 kW – unlike other sources of power (say, nuclear) that require much larger scales. This will ideally suit small villages that have only a few households. Also, this whole process could be done in rural areas, where this could open a gateway of opportunities for rural population. Given that a 1 MW biomass based power generation could require biomass growth in over 150 hectares, the opportunities for rural employment are indeed significant. Thirdly, biomass power results in no new net GHG emissions as it is part of the carbon cycle. Unlike coal and others forms of fossil fuel which have been buried millions of years ago and burning them adds to carbon in the atmosphere, responsible biomass energy generation results in no new carbon emissions or pollution. Finally, the efficiency of the biomass power generation process to make use of mostly animal and crop wastes for energy is remarkable. Also, there is a large variety of feedstock which could be used for the process. Aside from these, they also significantly reduce methane in the atmosphere, which being able to be produced economically. I suppose these are enough reasons to switch to biomass power.

Biomass based power

Biomass is a valuable physical mass of biotic factors and ideally suited for the energy generation in different forms for the fulfillment of human demands over time. Even though deep ground fuel resources of biological origin satisfy it comprehensively, the way it is oxidized today on a time scale for energy production alarms the world by a phenomenon called “Global warming”. It forces us to scan for a suitable and sustainable alternative to fossilized biomass and the answer lies with surface dwelling, active biomass which is derived either from live or dead sources for power generation. Biomass can be subjected to power generation by combustion principle which is exactly followed for fossil sources and also is found to have a greater flexibility to generate power than conventional sources. Besides combustion, biomass is readily amenable for gasification where energy as power, heat and synthetic fuels can be derived. Biomass based power proves to be highly profitable under conditions where natural resources such as wood from forests, agricultural and animal sources etc are at abundance. India is a potential hub for this alternative route of power generation but currently holds a marginal fraction of 2650 MW out of its total installed capacity of 172000 MW. It utilizes bagasse co-generation system as its major option for biomass based power production with a capacity of 1411.53 MW achieved till June, 2010. It is important to note that biomass based power is multi-dimensionally advantageous as follows Rural economic upliftment, Suited for rural areas, Ability to have small kW scale power production, Distributed generation, Carbon neutral, Efficient utilization of renewable biological sources and accession of low cost resource.

Biomass conversion to natural gas – is this being followed anywhere?

I and my team might be working on an interesting project where the company is trying to move away from natural gas for its heating purposes and into the use of biomass for the same. The reason of course has to do with economics, with natural gas prices shooting through the roof past couple of years. While we are figuring out ways in which the company could use biomass directly for heating instead of natural gas, this process poses some problems owing to the specific needs of the client. I am hence wondering if the process of converting biomass to natural gas is being followed anywhere. I know that this is pretty much feasible, but not sure about the technology maturity and economics. If there is anyone who is aware of commercial conversions of biomass to natural gas, do let me know. You can include your response in the comment section or send a note to narsi [at] eai dot in. Thank you.

Biomass Gasification for the Environment and Economy

There are a whole lot of benefits from biomass gasification, both economy wise and ecology wise. Speaking of environmental benefits, gasification plants produce significantly lower quantities of air pollutants, which is really a good thing.  The process can also reduce the environmental impact of waste disposal because it can use waste products as feedstock, generating valuable products from materials that would otherwise be disposed as wastes. Gasification's byproducts are non-hazardous and are readily marketable and also use significantly less water than traditional coal-based power generation, and can be designed so they recycle their process water, discharging none into the surrounding environment. If that is not convincing, let us look at the economical benefits. Gasification can be used to turn lower-priced feedstocks into valuable products like electricity, substitute natural gas, fuels, chemicals, and fertilizers. For example, a chemical plant can gasify petcoke or high sulfur coal instead of using high-priced natural gas, thereby reducing its operating costs. While a gasification power plant is capital intensive (like any very large manufacturing plant), its operating costs are potentially lower than conventional processes or coal-fired plants because gasification plants are more efficient and require less back-end pollution control equipment. With continued research and development efforts and commercial operating experience, the cost of these units will continue to decrease. The process also offers wide fuel flexibility. A gasification plant can vary the mix of solid feedstocks, or run on gas or liquid feedstocks—giving it more freedom to adjust to the price and availability of its feedstocks. Many predict that coal-based power plants and other manufacturing facilities will be required to capture and store CO2, or participate in a carbon cap and trade market. In this scenario, gasification projects will have a cost advantage over conventional technologies.

Biomass Gasification in India to Generate Lakhs of Jobs

Emerging green economy in the country may see creation of nine lakh jobs in India by 2025, a top government official said.

"India could generate nine lakh jobs by 2025 in biomass gasification, of which three lakh would be in manufacturing of stoves and six lakh in areas such as processing into briquettes and pellets and the fuel supply chain," Ministry of Micro, Small and Medium Enterprises (MSME) Secretary Dinesh Rai said.

More from here.

I am not sure if biomass gasification alone could generate almost a million jobs. The secretary appears to have his numbers done for him all right, but I still wonder.

It will of course be good if it comes true. It was only yesterday that I met this gentleman whose company manufactures efficient burners for kerosene stoves and he was quite hopeful about the micro-gasifiers as well.

Let's see how it goes

Biomass Gasification Power Production – Bottlenecks and Barriers

Biomass gasification is a process where materials are transformed by thermal decomposition under partially oxygenated conditions to generate syn-gas for power generation. It seems to be a powerful technique where energy can be produced in a sustainable way along with valuable products such as green oil and biochar but it is multi step process where bottlenecks continuously arises at every step of the production pathway. The most commonly encountered limitations are batch to batch variation in  energy content, purification of the syngas, contaminants influence in the performance of the engines, ash and biochar disposals, toxic gas emissions and operational efficiency of the gas engines and mandatory modifications required to make the engines energy effective. In addition to these prime technical problems, others notable hindrances are insufficient capacity of the stakeholders and inadequate institutional and policy framework at the national, regional and local levels and limited access to financing and lack of interest on part of the state electricity boards (SEBs) in promoting biomass power generation etc. In India, conditions are further complicate by lack of working capital, limited interest in power projects, lack of effective regulatory framework and absence of effective information dissemination etc. In spite of the limitations, the technology continues to gain acceptance. Its potential to meet the energy demands on a flexible scale makes a robust move to outweigh the magnitude of limitations associated with it.

Cons of Gasifiers

The use of biomass gasification for power production is not new, but its use has been so far been limited and its contribution to the overall power production has so far been negligible in India. The producer gas derived from biomass gasification can be used for either producing power (by use in a gas engine) or can be used for thermal applications. With better technologies evolving for both gasifiers and gas engines, it can be expected that biomass gasification could start contributing a lot more to the overall power production in India. For starters, biomass gasifiers are reactors that heat biomass in a low-oxygen environment to produce a fuel gas called the producer gas. The gas produced from a gasifier can drive highly efficient devices such as gensets, turbines and fuel cells to generate electricity. A biomass gasification system consists primarily of a reactor or container into which fuel is fed along with a limited (less than stoichiometric, that required for complete combustion) supply of air. Heat for gasification is generated through partial combustion of the feed material. The resulting chemical breakdown of the fuel and internal reactions result in a combustible gas usually called producer gas. Though gasifiers are really special in their own way, they have their limitations. Gasification is a complex and sensitive process. There exists high level of disagreement about gasification among engineers, researchers, and manufacturers. Several manufacturers claim that their unit can be operated on all kinds of biomass. But it is a questionable fact as physical and chemical properties varies fuel to fuel. Gasifiers require atleast half an hour or more to start the process. Raw material is bulky and frequent refuelling is often required for continuous running of the system. Handling residues such as ash, tarry condensates is time consuming and dirty work. Driving with producer gas fueled vehicles requires much more and frequent attention than gasoline or diesel fueled vehlicles. Getting the producer gas is not difficult, but obtaining in the proper state is the challenging task. The physical and chemical properties of producer gas such as energy content, gas composition and impurities vary time to time. All the gasifiers have fairly strict requirements for fuel size, moisture and ash content. Inadequate fuel preparation is an important cause of technical problems with gasifiers. Gasifier is too often thought of as simple device that can generate a combustible gas from any biomass fuel. A hundred years of research has clearly shown that key to successful gasification is gasifier specifically designed for a particular type of fuel. Hence, biomass gasification technology requires hard work and tolerance. As I said, gasifiers are indeed special in their own way. I’d rather we just wait for the technology to advance in the future to go far beyond its limitations. After all, as I said then and I will again, petroleum is not here forever, and we need more sustainable feedstock and advanced technologies for processing.

Cool Solutions for Your Hot Problems – Getting Your Heating Costs Under Control

industrial heating boiler 1 Sustainable Industrial & Commercial Heating Solutions - A Critical Pain Point No, this blog post is not about those hot problems. It is about problems companies, especially in the manufacturing sector, face for their heating requirements! With the prices of furnace oil, diesel and LPG increasing alarmingly in the past few years, companies suddenly find their costs of their energy shooting up to unaffordable levels. Suddenly, using renewable and sustainable energy sources such as solar and biomass, and utilizing heat that was wasted earlier appear to be the way forward. I hence thought I’d provide an overview of renewable and sustainable options available for heating requirements in factories. The following are the sustainable heating avenues that are technically feasible today:

  • Solar Water Heater
  • Biomass
  • Waste Heat Recovery/CHP/Cogen
  • CST (concentrating solar thermal)
  • Energy efficiency heating equipment
  • Back pressure steam turbine
Solar Water Heaters Yes, we are talking about the simple and common solar water heaters. Could they provide a solution for industrial heating needs? The answer is Yes. Solar water heaters typically can provide temperatures up to only about 70OC, while many industries such as food and diary will require temperatures upwards of 150 deg C. This should however not be a deterrent as solar water heating can be used to preheat the water.  To the extent that solar water heaters can be used to replace furnace oil or diesel, proportionate cost savings can be derived. Taking the current prices of furnace oil, diesel, LPG or natural gas, even partial substitution of any of these fuels with solar heat makes significant economic sense. The capital cost involved in setting up this solar water heater facility can be recovered in about 2.5 years at the current prices of fossil fuels. Biomass based heating Let's consider a factory currently using about 10000 m3 of natural gas per day (or about 10,000 liters of furnace oil per day) for this discussion. Such a factory can save considerably by switching over to biomass from fossil fuels for its heating applications. The advantage with biomass based heating is that it is a firm source of energy and can technically replace the entire fossil fuel use for 24X7 operations. Biomass–based heating is a fairly old idea, but today, this can provide more bang for the buck using the gasifier technology which is a much more efficient way to provide heating than direct combustion. Essentially, combustion is not the best way to derive heat energy from biomass. Gasification, by first converting the biomass into an organic gas called the producer gas, makes the entire heating process far more efficient as it is easier to control and optimize producer gas for combustion than it is to optimize raw biomass. Using gasification also provides small amounts of charcoal as a by-product. Charcoal commands a good value in the marketplace. Today, a number of plants in India and overseas are seriously looking at using biomass for their boiler as well as their other heating and drying applications. The economics of biomass are fairly simple. At the current prices of biomass (Rs 4-5 per Kg), a 50 T per day biomass based gasification can displace about 10000 m3 of natural gas  or about 10,000 l of furnace oil. Natural gas costs about Rs 40 per m3 and furnace oil about Rs 42 per liter. Thus, biomass based heating would cost Rs 2.5 lacs per day vs Rs 4 lacs approx for either furnace oil or natural gas. This translates to a saving of Rs 1.5 lacs per day for such a facility or over Rs 5 crores per year!  The payback periods for these are in the range 2-3 years. Waste heat recovery / CHP / Cogen Utilization of waste heat has become one of the most sought after ways in the manufacturing sector today. With available technologies, it is today possible to convert both high temperature waste heat as well as low grade waste heat into useful heat or cooling. Of specific relevance here are technologies such as vapour absorption chilling, stirling engine and organic rankine cycle power generation mechanisms. While stirling engine is arguably not yet ready for large scale, reliable commercial use, vapour absorption chilling is a mature technology today, and organic rankine cycle is already a commercially available solution. VAM (vapour absorption) route will be especially useful for factories having significant cooling requirements, either in terms of air conditioning or for chilling/refrigeration. CHP/cogen is already quite prevalent in the sugar mills and distilleries in India. For those facilities that have large amounts of waste heat, CHP is a viable and financially rewarding option. Concentrating Solar Thermal Until a few years back concentrating solar heat was used predominantly for power generation – known as concentrating solar power (CSP). But today, using the same CSP technology as the base but with lesser sophistication, solutions are available that allow concentrating solar heat to generate steam up to 200OC, something that can be used in many process industries for most of their heating purposes. This has opened up the new domain of concentrating solar thermal (CST). CST is today a commercial solution and has already been adopted / implemented at many process industries in the country including diaries, food manufacturing units, large canteens and kitchens and the like. In most case, CST might not be able to replace conventional fuel use fully. It has however been estimated that it could replace up to 75% for many installations. That can be a tremendous saving for companies that are bearing the brunt of fast increasing furnace oil / LPG / diesel prices. Unlike solar water heaters, which is a highly mature technology, CST is still undergoing significant innovations, thus making it possible for companies to have high efficiency and high productivity technology installations in the near future. CST has been shown to have payback periods of less than 3 years in the installations that it is already operating in India. Energy Efficient Heating Equipment I recall a trip I made to a well-known hotel in Chennai where the chief engineer said said that by just replacing one old pump with a new, efficient one, they were able to reduce about 5% overall in electricity costs. This moral is true for many heating appliances and equipment too - be they boilers, furnaces, ovens or kilns. Of course, the decision is usually harder as the capital costs involved in changing over could be considerable, as these heating equipments will usually form the bulk of the cost of the overall heating system. Back-pressure Steam Turbine Back pressure steam turbines are not exactly for thermal efficiency or for reducing your heating costs, but I thought I’d include these here as they still provide a better bang for the buck from the heat generated. Back-pressure steam turbines essentially use the extra pressure and temperature that are inevitably present in the process steam to drive a small non-condensing turbine to generate power. The steam that leaves this back-pressure steam turbine goes on to do the useful work. As mentioned earlier, while it does not provide heat at a lower cost, it provides more value for the same amount of energy used for heating, by generating additional power from it. Summary There, you have it. Using one more of the above six avenues, factories that use significant amounts of heat can achieve significant cost savings while at the same time becoming far more “green” and environment friendly. Wish to know more on how your factory could be made more green through sustainable heating solutions? Send a note to me - Narasimhan Santhanam  ( narsi@eai.in  ).

Costs of feedstock for Biomass gasification

Biomass gasification utilizes renewable feed stocks for liberating the synthesis gas by thermal decomposition under high temperature conditions. Among the factors affecting the production protocol, cost economics play a critical role and is well pronounced in cases when the scale of operation is magnified. Entrepreneurs of gasification technology often make contracts with farmers or traders so as to ensure a price security and timely uninterrupted availability of their concerned feed commodity. In spite of the strategies, price fluctuations in gasification feed stocks have been witnessed, for instance cost of rice husk was at Rs: 600/tonne in 2009 but has steeply increased to Rs 1800/tonne by the end of 2010 and such an extreme volatility in market prices causes a concern to buyers and affect the final price of the power/unit produced by biomass gasification technology. Lack of price security has produced an unique trend in gasification where the venturers start their own farms for feed stock production which they claim that it can cut costs by two-third of the actual cost and seems to be working well in particular with dedicated energy crops. Gasification technology is well balanced economically as entrepreneurs have a scope to sell biochar by-product which fetches good market price to compensate for the cost procurement of the feedstock. Socio-economic and technical factors continuing to challenge the progression of gasification but the productivity makes it a superior choice that cannot be camouflaged.

Current Status of Biomass Gasification in India

India has initiated its power generation from renewable sources by several different principles namely gasification and combustion. Biomass gasification is carried out at different power capacity levels ranging from 25 kW to 2 MW and above. When a comparative analysis is made between combustion and gasification of biomass, the former technology is best operational under high capacity installations while the inverse is true for the gasification. This peculiar advantage seen in gasification to operate at smaller ranges makes the technology suitable for adoption in rural and by small entrepreneurs where power generation is required rather than efficiency. The technology even though best functions with high range installations of 2 MW, its utility is obstructed by the demand for a series for engines and India has less than 10 installations so far. Gasification technology is really ideal where resources are randomized and adoption of any other technology is tedious on a financial scale. Gasifiers are flexible to operate which makes the user to follow any technology depending on his requirements to a limited extent.

Decarbonizing India’s Energy Sector by Biomass and Biofuels


This post is a part of DIL Intelligence series from Energy Alternatives India (EAI), India's leading climate-tech consulting firm.

DIL stands for Decarbonization for India's Leaders and provides comprehensive market intelligence and updates to Indian corporate leaders on prominent decarbonization efforts across the Indian industrial ecosystem. DIL is provided by EAI's strategy consulting team. More about our consulting from here.


In India, 22% of the total energy supply is renewables, with biomass contributing 85%. Biomass use is shifting from traditional residential heating to power production. Biofuels represent less than 1% of transport fuels, with bioethanol at 3% of gasoline consumption. The biomass market is projected to reach INR 32,000 crore by FY2030-31. India produces 450-500 million tonnes of biomass annually, with a surplus of 230 MMT/year. Biomass-derived energy constitutes 32% of India’s primary energy use. The biomass pellet manufacturing capacity is 2.38 MMT, with 83,066 MT co-fired in 39 thermal power plants.

Reliance Industries Limited (RIL) is transitioning from fossil fuels to renewable energy, including biofuels, for its energy demand. This involves using bio-pathways to fix CO2 and recycling materials across value chains. RIL plans to set up around 100 Compressed Biogas (CBG) plants over the next five years, consuming over 5.5 million tonnes per annum of agricultural residue and organic waste. This initiative is projected to reduce nearly 2 million tonnes of carbon dioxide emissions annually. In essence, RIL’s decarbonization strategy involves renewable energy, biofuels, recycling, and CBG plants.

Thermax, an Indian energy and environment engineering company, is decarbonizing its manufacturing processes using biomass and biofuels. Its subsidiary, TOESL, installs biomass-fired plants and sells steam. Thermax’s solutions include the Atmospheric Fluidised Bed Combustion Boiler, capable of using various fuels including coal, lignite, rice husk, petcoke, spent coffee ground, washery rejects, low ash coal, paper sludge, roasted chaffs, DOB, bagasse, pith woodchips, coffee husks, mustard stalk, cotton stalk, and char. Thermax has secured an order worth over Rs 500 crore to set up five bio-CNG plants across India, with a capacity to produce 110 Tonnes Per Day of bio-CNG, utilizing local feedstock exceeding 1,000 TPD. This initiative contributes to the decarbonization of manufacturing processes.

The shift from fossil fuels to renewable energy sources is a key aspect of the company's strategies. This transition is driven by the need for cleaner energy sources and the potential economic benefits of renewable energy. Development of advanced biofuels like bioethanol, biodiesel, and biogas from sustainable feedstocks like algae and dedicated energy crops can further reduce reliance on fossil fuels and enhance energy security.

Looking ahead, the focus will be on enhancing the efficiency of biomass and biofuel technologies, developing second-generation bioconversion processes, and ensuring the sustainable sourcing of feedstocks. The potential of biomass and biofuels extends beyond just energy production. It opens up opportunities for waste management, rural development, and job creation, contributing to a circular economy. Companies like Reliance Industries and Thermax are pioneering this transition, demonstrating the viability and benefits of these renewable energy sources.

Emerging Feedstock for Biomass Power

Following my previous post on the industry perspectives on the various methods that have to be adopted for sustainable feedstock procurement (http://eai.in/blog/2011/12/industry-perspectives-and-strategies-for-effective-biomass-feedstock-procurement.html), today’s article showcases the various feedstock (emerging) that could be used as  a potential source for biomass-based power generation. As you might be well aware, the first generation feedstock such as sugars, starches from wheat, sorghum, sweet potato etc are not widely used for bioenergy production owing to the food-fuel conflicts. Similarly, even the second generation feedstock such as mustard are not being used in a big way for bioenergy production. These days, more focus is being thrown on the advanced feedstock such as the third-generation biofuels ( these seek to improve yields through improving the feedstocks themselves instead of the processes). These feedstocks include those sources that promise to generate greater than 500 gallons of oil per acre per year. Examples include palm oil and algae oil, rapeseed and jatropha oil, grasses (switchgrass, miscanthus), trees (willow), halophytes (saltwater plants). Provided are some details of the emerging biomass feedstock such as camelina, miscanthus and bamboo and their potential to perform as a bio-fuel. Miscanthus: Miscanthus, also known as Elephant grass can grow up to 3 meters high and it is native to tropical and sub-tropical regions of Africa and South Asia. Miscanthus is mentioned as a biofuel crop because of its relatively high dry matter yields across a range of environmental and soil conditions. The Miscanthus genotype most commonly recommended for biofuel production is a sterile hybrid (Miscanthus x giganteus) believed to be a M. sacchariflorus x M. sinensis hybrid. Miscanthus utilization in the biofuel industry is primarily for combustion in power plants – it has the desirable properties of low water and ash contents. Current research is focused on its potential as a biomass crop for direct combustion and for lignocellulosic conversion to ethanol. Giant miscanthus has been studied in the European Union and is now used commercially there for bedding, heat, and electricity generation. Most production currently occurs in England but also in Spain, Italy, Hungary, France, and Germany. Recently, Japan and China have taken renewed interest in this native species and started multiple research and commercialization projects. In the United States, research began at the University of Illinois at Urbana-Champaign in 2001 and has expanded rapidly to other U.S. universities. However there is currently little published information on giant miscanthus yields in the United States. Bamboo: Recently, bamboo has received increasing attention for producing biofuel because of its easy propagation, vigorous regeneration, fast growth, high productivity and quick maturity. Bamboo is an efficient user of land, and produces more biomass per unit area than most tree species. But the process of converting bamboo cellulose into liquid fuel is difficult to execute efficiently because of the extraordinary density of the plant.  However, new research from Mississippi State University hold clues for how scientists can learn to more easily break down bamboo, and thus more efficiently extract biofuels from all other cellulose sources using the bacteria from pandas’ waste. If the researchers are successful, the manufactured enzymes could be used in a new, much cheaper and more efficient process for converting bamboo and other woody plants into biofuels. Fuel properties and potential as a bio-fuel of different bamboo species:

Species Moisture content Density Ash content Energy content
% g/cm3 % MJ/Kg
B.pallida 44 0.61 1.91 18.63
B.tulda 37 0.65 1.92 18.61
D.asper 37 0.77 4.23 17.92

Camelina Camelina, an oilseed, is a rotation crop for wheat that can be established on marginally productive land. It is an annual, short season plant. Biofuel from camelina is an ideal jet fuel substitute. Camelina has a number of advantages over its competitors, including using far less water, thus allowing it to be grown on marginal land, thereby not taking food acreage out of production. Furthermore camelina has a relatively short growing season of 80 to 100 days, requires no special equipment to harvest, and the silage remaining after processing can be fed to livestock and poultry, with the added side benefit of increasing their omega-3 production. Camelina is increasingly emerging as a prime biofuel source and thus attracts investment worldwide, as global demand for aviation fuel for passenger flights is now more than 40 billion gallons annually. In the earlier of this year, USDA announced two Biomass Crop Assistance Program (BCAP) project areas devoted to developing camelina as biofuel in several states, including Montana. USDA's Risk Management Agency (RMA) has also recently announced a new pilot program of insurance for camelina beginning with the 2012 crop year.

Future Feed-in-Tariff Trends for India – for Wind, Solar and Other Renewable Power Sources

It is an open secret that renewable power requires incentives - these usually are in the form of capital subsidies, tax incentives and most importantly, via feed in tariffs. It is a million dollar (make that Billion Dollar) question what the future of feed in tariffs will be for the mainstream renewable power sources. I picked up some resources on these. Wouldn't say they provide a peek into the future, but at least one of these try telling us how the government arrives at these numbers, so that will provide us with some clues.

 Most of us have come across the gobar gas – literally meaning gas from the cow. It is the same as what is called biogas. This is the gas that is released when bacteria feast on organic matter – typically human and animal feces – and release a gas that is about 50% methane. While biogas had predominantly been used earlier for heating purposes, its use for power production is also beginning to show a marked rise across the world, and in India too. How is power produced from biogas? The process is actually quite simple. Step 1 is generation of biogas. This is done typically using what are anaerobic called digesters. Animal (or human) waste is fed into the digester, where the microorganisms (called methanogenic bacteria) act upon it. Depending on the type of digester, it could take anywhere between 10 days to 15 days for the waste to have been "digested" by the bacteria and the release of biogas. The biogas thus produced can be used in IC engines specially devised for the use of biogas. These engines are similar in working principles to diesel engines and natural gas engines. These engines produce electricity from biogas. A bit of observation will lead us to easily understand why this concept will be of enormous interest to specific industry segments. Two segments stand out - industries that employ large numbers of animals and sewage treatment plants that treat human waste. Both these segments have started benefitting from this concept; as a result, we have a few STPs (sewage treatment plants) already generating power from the sludge generated (one of the STPs at Chennai, at a town called Nesapakkam, generates about 500 kW of power from the waste, and uses the power generated for all its electricity purposes). Some numbers will help understand the potential available for power generation from biogas. The cow population of India (about 225 million) alone generates about 800 million tons of wet dung which translates to about 150 million T of dry weight. 1 Kg of dry cow dung can generate about 1.2 kWh of electricity (it can generate the equivalent of about 4 kWh thermal). Thus, if all cow dung were converted to electricity, that would be 1.2*150*1000 million kWh = 180 TWh. India generated a total of 855 TWh in 2011-12. This implies that cow dung, if entirely converted to power, would have produced about 20% of total India's power! If the waste of other cattle and human waste were also taken into account, this could be about 30%. That is an awesome number. Of course, these data hide the actual difficulty in converting even a small portion of animal or human waste into electricity, owing to the infrastructural and social problems associated with these. All the same, waste -> biogas -> power is quite practical to a whole host of industries for whom such waste is available on premises. More information about waste to energy in general in the Indian context, is available from EAI's waste to energy resource section. Some of the following YouTube videos provide a more visual account of how to generate biogas from organic waste: Biogas from food waste - ARTI - http://www.youtube.com/watch?v=BGSl72xZHNk&feature=related Bio-gas from kitchen waste and bio mass - http://www.youtube.com/watch?v=uppVZGS7bYI&feature=related Biogas from Vegetarian Food Waste - http://www.youtube.com/watch?v=NZFrPZZIFTs&feature=related Biogas from Human Waste - http://www.youtube.com/watch?v=_m1nr2v5S8o And while on sewage, human waste and toilets, etc, a couple of interesting articles on things are emerging New toilet technology after 150 years of waste The seat of power - Better sewage treatment is the latest thing in clean energy Also check out: EAI Consulting for Bio-energy & Biofuels, Bioplastics & Other Biomass-based Value Added Products

How Punjab Will Benefit from All Its Agricultural Residue- A Case Study

Agricultural residues never go to waste. Not when they can be used for generating energy. In this context, the government of Punjab, India, plans to produce about 1,000 MW of green energy from livestock residues by 2015. When you think about it, this has huge economical and environmental benefits. In a region where large quantities of cattle manure become a major pollutant, this could be seen as an opportunity that could open a lot of doors. Aside livestock residues, the state also generates nearly 21 million tons of rice stalks and similar biomass plant wastes annually, which can all go into the production of green power. The state government is thus planning to make renewable resources as the source of their power to contribute 10% of its total energy production in the next five years. It is worthy to mention that Punjab already runs a biomethanation facility with a capacity of 1 MW, in a location close to Ludhiana. The facility uses methanogens (microbes that produce methane as a metabolic by-product) for the manufacture of methane gas. It currently uses 235 tons of cattle wastes to generate 18,000 kWh of electricity in addition to producing 45 tons of organic fertilizer every day. Also, the Punjab Energy Development Agency has developed 318 MW of green power projects, which includes the Ludhiana plant, till date. These projects comprise 37 MW of small hydro facilities, 28 MW of biomass power facilities, 250 MW of biomass co-generation facilities and 2 MW of solar projects. The agency also develops 132 MW of green power projects currently, which include 11 MW of hydropower, 100 MW of biomass co-generation and 20 MW of traditional biomass. If everything goes right and operational, the state will generate 700 MW of green power by 2012. That’s big! It is worthwhile to note that the planters are also getting an income of nearly RS. 4,000 per acre every year in the process of marketing agro wastes to biomass facilities.

Industry Perspectives and Strategies for Effective Biomass Feedstock Procurement

===========================================

Are you looking to get energy security for your company through reduction in the use of diesel, furnace oil, LPG and costly grid power? EAI can do a feasibility study for the use of solar PV & thermal, biomass for heat and power, waste heat recovery and energy efficiency to dramatically cut down fossil fuel use and reduce your energy bills. See EAI's SURE-FIRE offering for more.

 ===========================================

One of the most critical bottlenecks for biomass power plants is the supply chain bottlenecks that could result in non-availability of feedstock. A related problem is the volatility, or more precisely increase, in the feedstock price. Both these could render the project unviable. Highlighted in this article are some of the industrial perspectives in overcoming barriers for procuring a balanced feedstock supply. EAI’s research with industry experts suggest that there is no established biomass value chain that exists in India for the procurement and transportation of the biomass feedstock. Typically, the facility staffs  from a biomass gasification plant acquires biomass from several to dozens of small-scale biomass suppliers on a relatively informal, non contractual basis; although some have considered the use of aggregators, there is no data or proof available from the Indian biomass gasification companies that have engaged such a service as yet. The biomass procurement model that is typically followed in India is discussed below: Route #1 – Biomass Producer -->Transport Contractor --> Biomass Collection Centres (BCC’s) --> Power Producers The biomass producer i.e. the farmers/mill owners hands over the feedstock to a transport contractor who in turn delivers the feedstock to the biomass consumers or BCC’s. The BCC’s (managed by the biomass consumer) pay the farmers and the power producers collect the feedstock from these collection centres as and when required. At some instances, the farmers deliver the feedstock in the power producer’s facility and get directly paid for it. Route #2 - Biomass Producers --> Waste Processing Mills -->Biomass Power Producers For feedstock where further processing is required, the farmers/mill owners deposit the feedstock in waste processing mills. From the waste processing mills through a transport contractor the feedstock is deposited in the BCC’s or directly in the power producer’s facility. In some cases, especially in briquetting, the processing is done in the collection centres itself where a mobile briquetter is taken and the briquettes that are processed are directly delivered to the facility or collected by the power producers. Key Strategies to be Followed for Effective Biomass Feedstock Procurement EAI’s interactions with the industry reveal that the following strategies have to be adopted   in order to bring both the availability and price of biomass under control:
  • Security should be addressed by obtaining a written formal supply agreement with a reputable, local supplier. A five-year signed supply agreement with pricing and minimum volumes can go a long way in helping to secure necessary financing. A bioenergy project that is totally reliant on only one source of feedstock will be at risk, so two supply contracts are even better. This will also allow one to negotiate a better feedstock price, as the supplier will benefit from a long-term relationship and a guaranteed market. An interested lender needs to know that both the feedstock supplier and bioenergy processor are committed to the project.
  • It can be beneficial to hire an independent professional to verify one’s biomass supply projections and double-check that the feedstock supply is sustainable over the long term
  • Backward integration and own captive biomass source (one company, Orient Green Power, is even trying out a novel technique of going for energy plantations on their own wind farms)
  • According to the Washington based biomass supply company ‘Powerstock’, for a well-managed supply, an inclusive definition of biomass is needed. The company is also taking efforts to educate the public on the value of well-managed, productive forests.
  • The bottom line of feedstock security is composed of several aspects: grower relations, harvesting, marketing, equipment utilization, proprietary techniques and agricultural economics. Hence it's important to manage the entire process from seed to market.
  • The supply sector needs to make the transition from a residues-based approach to an integrated, dedicated feedstock supply system using energy crops, plus residues.

Potential for Biomass Power in India

Biomass based power generation is a choice of reality under the geographical regions where a sustainability exists in the flow of biologically raw materials for the production of power and India is one of the most notable universal giants for the production of biomass based power which can be best understood from the estimates of its biomass availability and the power produced from it. India has biomass production of 546 million tonnes per year from the agricultural sources alone to generate electricity at a capacity of 17,982 MW and its overall production of power from renewable sources stands at 34961 MWe in 2010.A calculated annual growth rate for the next decade realistically and optimistically is above 42,000 MWe and 48640 MWe respectively. The development of biomass based power is further enhanced by the Government regulatory policies by declaring duty exemptions’, tax breaks and financial incentives etc. The cost of producing electricity from biomass is affordable at Rs: 2.25-3.25 / kWh. In spite of all these attempts biomass based power generation is at its infant stage because of hindering factors such as feedstock availability, transportation, price volatility etc. India to emerge as a role model must utilize its renewable energy sources to a large extent, develop dedicated energy crops, establish end user market for co-products such as charcoal, biochar, activated carbon, and implement energy efficient technology for economically feasible power generation on a massive scale.

Mitsui, a leading Japanese conglomerate, has recently invested ₹4.1 million in Punjab Renewable Energy Systems Pvt. Ltd. (PRESPL), a company focused on collecting agricultural residues and converting them into biomass briquettes and pellets. This investment underscores the growing potential of the Indian biomass sector, which is expected to witness significant growth in the coming years.

The Indian biomass market is estimated to be valued at around ₹50,000 crore and is projected to reach ₹1,00,000 crore by 2025, driven by factors such as the Increasing demand for renewable energy, Growing awareness of environmental concerns, and  Supportive government policies.

The Indian biomass sector is also witnessing a surge in international collaborations, with several prominent companies entering the market through partnerships and alliances. For instance,  Aramco, a prominent oil and gas company, joins forces with ReNew Power, India's largest renewable energy company, to explore opportunities in developing and deploying low-carbon technologies, including biomass-based power solutions. This collaboration signifies the growing interest of leading energy giants in exploring cleaner alternatives. 

Additionally, Danish Biogas's collaboration with the Maharashtra Energy Development Agency (MEDA) brings together expertise in advanced biogas technologies with experience in promoting renewable energy and rural development in Maharashtra. This partnership contributes to a more sustainable waste management system through biogas generation..

These strategic partnerships are just a glimpse into the exciting developments propelling the Indian biomass sector forward. The government is also playing a crucial role in accelerating its growth through supportive initiatives like subsidies for setting up biomass power plants and briquette/pellet production units, promoting dedicated energy crops and efficient residue collection systems, and providing tax benefits for biomass projects. Investments in research and development are also being made to improve conversion technologies, optimize feedstock utilization, and develop cost-effective biomass solutions.

Navigating this complex ecosystem requires a comprehensive understanding of the key players involved. The Indian biomass value chain comprises various stakeholders, including biomass producers like farmers and forestry companies, collectors and aggregators responsible for managing feedstock collection and storage, processing and conversion companies that transform biomass into usable forms, original equipment manufacturers (OEMs) who create machinery for the sector, suppliers providing essential goods and services, power plants and industries utilizing biomass-based fuels, and government agencies responsible for regulation and promotion.

Beyond the core value chain, the adjacent value chain plays a crucial role in supporting the sector's growth. This includes financial institutions offering loans and investments for biomass projects, research institutions and universities engaged in R&D advancements, and non-governmental organizations (NGOs) promoting sustainable practices and advocating for policy changes.

Indigenization remains moderate to low currently, with reliance on imported technologies and equipment. However, government initiatives and rising demand are expected to gradually increase domestic capabilities in the coming years.

Primary Routes for Power from Biomass

The three primary routes for biomass to power are: Combustion, Gasification and Anaerobic Digestion. Combustion is easy to understand – instead of using coal or other fossil fuel, use biomass to produce steam that runs a turbine. Combustion of biomass for power could either be in the form of co-firing (when it is burned along with coal) or pure play biomass based combustion. In the case of gasification, the biomass is first gasified and this gas turn produces power in a gas engine. Anaerobic digestion is usually applied to biomass that typically have a high amount of water in them (anaerobic digestion is most used for treating organic waste such as kitchen waste and sewage waste into energy). Under this route, microorganisms act upon the organic matter present in the biomass under anaerobic (absence of air) and convert it into biogas. An emerging route for biomass based power is pyrolysis. In this, the biomass is rapidly heated to 450 - 600 °C in absence of air, and results in a bio-oil called the pyrolysis oil, which can in turn be used for firing the boilers. Typically, 50 - 75 % (by weight) of the feedstock is converted into pyrolysis oil. Pyrolysis as a method for power production is not well established currently in India or elsewhere in the world. Typically pyrolysis plants work well beyond 2 MW scale, while gasification plants work well until 2 MW scale, at the current technological progress. Thus, it can be said that pyrolysis takes off where gasification ends. Also check out: EAI Consulting for Bio-energy & Biofuels, Bioplastics & Other Biomass-based Value Added Products

Prominent biomass feedstock for gasification

Biomass for power generation by combustion or gasification is normally variable in its chemical composition of electron rich reactants, ash content, moisture, sulphur and nitrogen content etc. As a result, selection of the most convenient feedstock is an issue of debate. The degree and diversity of contaminants strongly influence the production and purification of synthesis gas in gasification while they tend to have a minimum effect in the combustion process. Independant of these disturbances virtually any raw material applied in power generation process should be a matter with potentials. In India, a vast array of feed stocks are utilized for power generation but the most wide ones are farm and mill wastes, woody trees, energy plantations and other green manure crops. Preference is made on the basis of availability, cost, bulkiness of the material, pre-processing, storage etc. Biomass used in India yields varying level of energy but it is also the gas engine and generators whose efficiency equivalently determine power generation.

REC Price Band Revised

The Central Electricity Regulatory Commission(CERC) has announced the floor and forbearance prices to be used for solar/non-solar projects from the FY 2012-13 upto 2016-17. The prices set are shown in the table below

Non Solar (Rs.) Solar (Rs.)
Prices (2012-2017) Current % Reduction Prices (2012-2017) Current % Reduction
Forbearance Price 3300 3900 15.38 13400 17000 21.18
Floor Price 1500 1500 0.00 9300 12000 22.50
Background Earlier, the CERC had proposed a few changes (refer table below) to be made to the REC prices and invited comments/suggestions on the same.
Non Solar (Rs.) Solar (Rs.)
Proposed Current % Reduction Proposed Current % Reduction
Forbearance Price 3480 3900 10.77 13690 17000 19.47
Floor Price 1400 1500 6.67 9880 12000 17.67
  The final prices to be enforced from April 2012 were arrived at after considering the comments/views of stakeholders and participants at the public hearing on the proposed floor and forbearance prices. As can be seen, the final prices decided upon are considerably lower than the earlier proposed prices. Analysis Financial feasibility studies of power plants under the REC mechanism almost always consider the floor price for calculating returns. With this in mind, the evaluation of REC for the primary renewable energy generation systems looks quite healthy.
  • Non-solar – the floor price remains unchanged. Thus biomass/wind generators are expected to get the same minium revenue as they have been getting earlier.
  • Solar – the floor price has seen a cut of about 23% from current levels. Although this might seem drastic, it is not likely to have a significant impact on solar power projects (refer section below).
  APPC – Non preferential tariff and REC CERC stipulates that for a project to be eligible under the REC mechanism, the power producer has to sign a PPA with the state utilities at a price equal to the APPC price. The APPC price for a state for a particular time period is determined by the State Electricity Regulatory Commissions(SERC). Looking at the current APPC prices in various states, a combination of REC and a PPA signed at APPC rates seems comparable with the preferential PPAs signed with the state utilities. For example,  let us consider a solar PV plant to be setup in Tamil Nadu where the APPC price for 2011-12 is Rs. 3.38/kWh. Under REC regulations, if a RE developer were to get the floor price for the solar REC, the income for the solar PV plant would be Rs. 12.68 /kWh (Rs. 3.38 + Rs.9.3). Another case is Rajasthan, which has a very high potential for solar PV – where the income would be Rs. 11.9 /kWh. In comparison, under the phase 1 (batch 1) of JNNSM, the average price settled on through the reverse bidding process was  about Rs. 12.5 per kWh. As can be seen, these prices are comparable to tariff set through reverse bidding under batch 1 of the JNNSM scheme. Prices can only go higher APPC prices are set based on the cost of power generation from fossil fuel based power plants. It is highly likely that this price would increase in the future due to the increase in fossil fuel prices and scarcity of supply. This ensures that the APPC prices would continue to increase for the foreseeable future, thus ensuring higher year on year returns under the REC mechanism provided the PPA signed with the state utilities has provisions for purchase at floating APPC prices rather than fixed price. The table below gives a comparison between preferential tariff (reverse bidding under JNNSM) and REC mechanism for a plant in Tamil Nadu. The following assumptions were made for the sake of calculations
  • Average bid price under phase 1 batch 2 of JNNSM could be around Rs. 12.5 /kWh(on the higher side)
  • APPC prices could rise by 15% annually (base price used is that of Tamil Nadu) - reasons for this were mentioned earlier.
  • REC price after 2016-17 period (i.e. from FY 2017-18 onwards) is reduced by 25%
 
Year 2012 2013 2014 2015 2016 2017 2018 2019 2020 2021
JNNSM Tariff (average) (Rs. per kWh) 12.5 12.5 12.5 12.5 12.5 12.5 12.5 12.5 12.5 12.5
APPC (Rs. per kWh) 3.38 3.89 4.38 5.04 5.38 6.19 6.38 7.34 7.38 8.49
REC (Rs. per kWh) 9.30 9.30 9.30 9.30 9.30 6.98 6.98 6.98 6.98 6.98
Total (Rs. per kWh) 12.68 13.19 13.68 14.34 14.68 13.16 13.36 14.31 14.36 15.46
REC mechanism's Incremental revenue over PPA(Rs. per kWh) 0.18 0.69 1.18 1.84 2.18 0.66 0.86 1.81 1.86 2.96

Table: REC vs preferential PPA for 10 years post 2012

As can be seen from the above table, the REC mechanism is quite comparable, if not better when compared to the assured tariff provided by NVVN over 10 years of operation of the solar powerplant. Overall, the REC mechanism can clearly drive the solar market, provided the Renewable Purchase Obligation (RPO) is strictly enforced by the various SERCs. The CERC release can be found here.   Also check out: EAI Consulting for Bio-energy & Biofuels, Bioplastics & Other Biomass-based Value Added Products

REC Trading – November 2011

The REC trading for the month of November concluded yesterday. Figures reveal that the trading has increased significantly both in volume of RECs traded as well as the price. In total 105,527 RECs were sold. Keeping with the trend of previous months, IEX had a higher share of the market with 96,154 (90%) RECs traded while PXIL saw trading of 9,373 (10%) certificates. The large volumes of trading indicate that the obligated entities are trying to fulfil their RPO as soon as possible as REC prices are showing an upward trend. The price of REC varied between the two exchanges - IEX and PXIL. Non-solar RECs closed with a price of Rs. 2,900 at IEX while the RECs sold at Rs. 2,800 at the PXIL. At the IEX, the prices have seen a 7% rise over those paid last month where the trading price was Rs. 2,700 per REC.

September Non-Solar Solar
Buy Bids Trade Volume Sale Price Buy Bids Trade Volume Sale Price
IEX 257,578 96,154 2,900 43 - -
PXIL 51,199 9,373 2,800 0 - -
Total 308,777 105,527 - 43 - -
Interestingly, there are 43 buy bids for solar REC; this suggests that the solar REC market is gathering steam. This growing interest suggests that solar projects being planned based on REC may soon be bankable and we could see a trend in developers going for the REC mechanism during the interm period between now and the second phase of the National Solar Mission. Solar developers have another reason to rejoice as well as maintain a shrewd view on the Solar REC market. This month saw the accreditation of the first Solar project under the REC mechanims - an 8.5 MW solar project located at Jalgaon, Maharasthra developed by Jain Irrigation Systems. This project's viability has to be closely followed over the coming trading sessions as the REC certificates generated from the project slowly start coming up for sale. In total there are about 244 projects registered under REC with an aggregated capacity of 1551.92 MW (this excludes the lone solar project that recently got accredited). Conclusion The REC market continues to impress with higher sale prices and volumes. The REC prices are expected to rise over the coming months given the fact that there only 4 months left for RPO compliance. However, the price as such is expected to rise only gradually and not at the high rates seen over the year. The registration of a solar project under the REC mechanism might open the flood gates for more solar projects depending on the performance of the solar RECS. This could lead to a pradigm shift in the solar project development in India, which up until now has looked up to the state/central solar policies as the only source for project viability thereby reducing the cost of solar power in India and accelerating the road to grid parity.   Also check out: EAI Consulting for Bio-energy & Biofuels, Bioplastics & Other Biomass-based Value Added Products

REC Trading – September 2011

The REC trading for the month of September concluded recently. Trading figures reveal that the trading has increased significantly both in volume of RECs traded as well as the price. In total 46,362 RECs were sold. Keeping with the trend of previous months, IEX had a higher share of the market with 41,385 (89%) RECs traded while PXIL saw trading of 4,977 (11%) certificates. The large volumes of trading indicate that the obligated entities are trying to fulfil their RPO as soon as possible as REC prices are showing an upward trend. The most encouraging part of the trading was the price paid for each certificate. The price of REC grew to Rs. 2300 from Rs. 1800 last month.

Interestingly, there are 7 buy bids for solar REC; up from the lone buy bid last month, although this is promising, it highlights a serious issue. As with the previous months, there are no solar RECs available as no projects are registered under REC. This is a worrying trend and is going to put immense strain on the obligated entities to fulfil their solar RPO. The reasons for lack of solar projects registered under REC could include

  • Higher payback period for solar projects
  • REC prices guaranteed only up to 2016-17
  • A combination of the above two greatly reduces the bankability of solar projects
Conclusion The increase in REC trade volumes and price is very encouraging. It shows that the mechanism is a viable revenue route for developers who have not signed any preferential PPA. The demand for REC certificates is bound to keep increasing as more and more obligated entities try to fulfil their RPO in the short time span available. This is scheduled to push the REC price even further which in turn could lead to REC prices hitting their forebearance highs in the coming months. Finally more effort needs to be put in to ensure that there is sufficient supply of solar RECs in the market.

The effect of each of the raw material for a module(metallisation paste, ribbon, flux, encapsulant,etc) on the final quality of the PV module was also discussed. That concluded the 3rd edition of the Renewtech India conference. The 4th Renewtech India conference is scheduled for 16-18 February 2012 at the same venue – Bombay Exhibition Centre, Goregoan, Mumbai.

Rice husk used for power in one of India’s poorest states- A case Study

Whoever thought rice husk can generate power needs a medal! Considering how much rice husks go to waste in a country where rice is the staple food, it is comforting to know fossil fuels are not our only resort for power production. Thanks to Manoj Shinha, a renewable energy entrepreneur pioneered using discarded rice husks as biomass to provide energy to Bihar, one of India’s poorest states. Mr. Shinha along with his colleagues Gaynesh Pandey, Ratnesh Yadav and Charles W. Ransler developed Husk Power Systems to address the situation of poverty in their home state of Bihar. Many villages in India live off the grid in the darkness, this new advancement means that they need not depend on grid for electricity, rather generate their own clean, affordable electricity.The company generates and sells electricity for a price that is less than half of what the villagers pay for kerosene. This was possible because the whole concept is focused on research and development investment to simplify energy production and transmission, such as using bamboo instead of cement posts to install power lines.And, since communities no longer use kerosene, wood or dung for electricity, this way of electricity generation lowers the environmental and health hazards. In addition, rice husk ash, a byproduct of the gasification process, can be used for concrete production thus reducing the amount of high-carbon Portland restless leg syndrome cement.On average, a single power plant serves 400 houses, replacing 42,000 liters of kerosene and 18,000 liters of diesel yearly. As of August 2010, H.P.S. has sequestered 50,000 tons of carbon dioxide. Currently, they have installed over 60 mini-power plants that are 100 percent biomass-based which supply power to over 25,000 households in more than 250 villages.With the market opportunity in mind, they aim to expand their business to bring clean electricity to Indian villages by installing 2,000 new plants by 2014 beyond Bihar.

Tamil Nadu’s Biomass Power Plans – Energy Plantations is the Answer?

Biomass is one of the renewable energy domains in which Tamil Nadu could have significant potential for progress in future. Estimates suggest only about 10% of the potential has so far been utilized. Of course, the lack of a robust supply chain that make create supply and price security is a problem as much in Tamil Nadu as it is in the rest of the country. Some inputs and updates for biomass power in Tamil Nadu are provided below.

  • Potential for Biomass based power in Tamil Nadu is 1589.9 MW (1160 MW based on agricultural waste and 429.9 MW from forest and wasteland cultivation).
  • 22 biomass power plants with total installed capacity of 169 MW are in operation.
  • Ten biomass power plants with totaling to 120 MW, with over 80% plant load factor, have faced temporary shut downs owing to unviable tariff rates and increasing feedstock cost.
  • Biomass power producers association has approached Tamil Nadu Electricity Regulatory Commission (TNERC) with a request to revise the tariff and offer higher annual tariff escalation. The viable rate for operating biomass power plants in years to come would run beyond Rs 6.50/kWh, but the current tariff of Rs 4.5/kWh is in no way adequate to sustain the projects in the long run.
  • Tamil Nadu Energy Development Agency (TEDA), along with Tamil Nadu Biomass Power Producers Association, has been actively involved in promoting large scale energy plantations in marginal / waste land in the state with high potential crops.
  • The Tamil Nadu Biomass Power Producers Association suggests that energy plantation would not only serve to provide cheap and continuous feedstock supply for power plants, but it would also improve the quality of life of the rural population. Estimates suggest that a 10 mw biomass power plant can ensure livelihood of over 2,000 marginalised families. They can be employed in collection, transportation, cutting, chipping of biomass and cultivation of wasteland with energy plants like Juliflora, Bheema Bamboo etc.
So, it looks like Tamil Nadu is betting significantly on energy plantations for a viable biomass power sector. Let’s hope they have got it right. Also check out: EAI Consulting for Bio-energy & Biofuels, Bioplastics & Other Biomass-based Value Added Products

The man propelling the bio-energy movement in India – PRESPL

Welcoming Lt Col Monish Ahuja to CLIMAFIX SUMMIT 2022 - the 1st summit for Indian climate tech startups. I'm sure you have heard the saying, "Water, water everywhere, not a drop to drink" That applies quite well to the Indian agricultural residues as well. Hundreds of millions of tons of agro waste around the country, but very little available for the industries to use. And worse, a good portion gets burnt on the fields because the farmers do not know what to do with them. So where's the challenge? What is broken in this system? To a significant extent, logistics, or rather the lack of it. Securing and transporting millions of tons of agricultural waste from hundreds of thousands of farmers and transporting it reliably to end users is not rocket science. But it is systems science. Discipline science. Or patience science, if that term is more endearing to you. In EAI's decade long work in the bio-energy sector during which we consulted for dozens of clients including the likes of GSK (#Horlicks division, now part of Unilever), we have seen how unorganized the agro-waste supply has been, except for bagasse coming straight from large sugar mills and to a lesser extent saw dust from plywood factories. It is a complex challenge of logistics, societal & local traditions, and of course the omnipresent politics. The sector needed someone who could wade through all these, build an efficient system and evolve an organized biomass supply chain. Enter Lt Col Monish Ahuja. Army discipline, Systems thinking. Business acumen. These characteristics have helped him build Punjab Renewable Energy Systems Private Limited (PRESPL) into a force to reckon with countrywide in industrial biomass supply. PRESPL is today is one of the few organized players that has the ability to provide industrial decarbonization on scale through biomass, supplying thousands of tons of agro-waste based biomass every day to industries. I remember sitting with him in his office in Navi Mumbai a few years back when he patiently took me through the process by which he was building an effective front-end logistics system while also putting together a scalable digital back-end system. While coming out from the meeting, I thought - finally, here's someone who appears to be just what the doctor ordered for India's bio-energy sector. Since then, his company has - not surprisingly - grown and grown. Hats off to Monish, and we are proud to have him as one of the experts who will share his insights at the CLIMAFIX SUMMIT 2022, India's first climate startup summit, Nov 25 & 26, Chennai, organized by the Climate Startup Intelligence division CLIMAFIX of EAI (Energy Alternatives India) & Energy Consortium - IIT Madras Welcome Monish, and here's hoping you inspire more of your breed - and soon.

VC / PE Perspectives and Opinions on Biomass Power

Indian VCs have not really done a good amount of investing in cleantech. Cleantech perhaps  is not really a VC game as it is more of an engineering related discplie that does not offer the types of scalabilitiees that VCs desire or the exit periods. VCs also do not understand cleantech well enough to take calls. Many cleantech deals, especially in the power segment, are PPA based, with limited upsides, not typical VC games. Many cleantech and renewable energy startups require capital that is much higher than what VCs can typically offer to invest. Predictions for Cleantech VC in 2011 - Kachan & Co.'s Dallas Kachan looks at what 2011 will have in store for cleantech (http://alwayson.goingon.com/node/66783 ) Sustained worldwide venture capital investment will continue to cede importance to corporate and non-institutional capital. A return to early stage venture investments - predict a return to early stage venture capital investing in cleantech in 2011. Energy efficiency emerges as the clear rock star of cleantech. Biofuel investment could reach former highs. Recycling and mining will attract more investment. Natural gas emerges to threaten solar and wind for utility renewable power generation. China becomes the most important market for cleantech: if you're not selling in China, you won't matter. There is a significant amount of interest among PEs for investments in both traditional and renewable energy. PEs – not surprisingly – are not very keen on risky technology bets in renewable energy, but are OK with business model risks. Some of the PEs (such as IFC, ADB etc) are willing to take fairly long-term views (with over 10 year horizon). Investment sweet spot ( in terms of the quantum) varies from fund to fund, but obviously for most of the blue-chip, it is upwards of $50 million. PEs are well aware of the regulatory and societal bottlenecks that could arise in large-scale energy sector investing (especially for coal-based and large-hydro based sectors). Many PEs are clear that they wish to invest in businesses that can stand on their own revenues (even if takes a while) and are not keen on business plans that rely on getting bought out. Most every PE acknowledged that while they might not like coal, it is here to stay as the largest contributor to power for the foreseeable future. PE arms of organizations such as IFC and ADB, while not shutting out the option of investing in coal-based or natural gas based power plants, have a mandate to decrease their exposures to these “non-green” sectors. What a PE can bring to the table - Many private equity funds have been able to provide not just the financial support required but also strategic support and value-add for the firm’s growth. Disconnect in Valuation expectations - one of the issues faced by PE players while investing in cleantech companies is the disconnect in valuation expectations between the entrepreneur and investor with the buoyant public markets resulting in an increasing buoyancy in expectations! PEs feel that entrepreneurs should take a longer term view while setting their valuation expectations. Currently, 80% of infrastructure projects, and 46% of power projects, are funded by the banking system. So, PEs constitute only a small share of the infrastructure projects. While private equity folks could like IRRs of about 25%, power and infrastructure IRRs is only about 12%. Some private equity companies might wish to play a consolidator’s role as well where they consolidate a diverse portfolio of (say) energy companies such that they win even if 7/10 companies do well enough. Investors such as IFC have specialists/experts in every project to take care of social and environmental aspects. Private equity funds are interested in the macro factors (demand supply gap in electricity et al) as well strategic micro factors. One of the factors that seem to interest PEs is the method for companies to go diversified on green power that is having assets in wind, small hydro, biomass etc together, instead of betting just on one thing alone.

Why Biomass for Power Generation?

Biomass has been used as a source of energy right since mankind started its existence; In fact, one of the predominant energy sources today is biomass. Biomass as a source for power production is not entirely new either. Biomass has been used, in the place of coal, for steam generation at power plants, though in a limited way. Indeed, currently, the predominant method used for producing power using biomass still is the combustion route, At the same time, other processes, such as biomass gasification, which can work at much smaller scales and use the biomass more efficiently are emerging. The newer processes especially biomass gasification based power production, is relevant today especially in the Indian context mainly because of its potential to provide distributed power at rural level, especially for small remote villages that have good access to biomass but no access to grid power, and which require only small scale power production. Biomass based power is also relevant in the context of climate change and global warming as biomass based power production is net carbon neutral. The contribution of bioenergy to the total primary energy consumption in India is over 27% (Source: FAO). This is indeed the case for many other countries, because biomass is used in a significant way in rural areas in many countries. However, the contribution of biomass to power production is much smaller than this percentage – currently, biomass comprises only about 2650 MW of installed capacity, out of a total of 172000 MW of total electricity installed capacity in the country. Besides, biomass power has the following benefits- distributed generation, baseload power, ability to have small, kW scale power production, suited for rural areas and ideal for rural economic upliftment. I believe these are enough to justify why biomass is best suited for power production. Check out: EAI Consulting for Bio-energy & Biofuels, Bioplastics & Other Biomass-based Value Added Products

A 900 MW Power Plant Running on Biomass? It Could be a Reality in Five Years!

I thought I was never going to see the day when a large power plant would run entirely on biomass. You can understand my pessimism when you are told that a MW of powerplant will require about 8000 T of biomass every year. A 300 MW power plant will hence require an awful 2.5 million T of biomass every year. That's a heck of a lot of, well, anything. Well, there are some courageous folks around the world. Drax in the UK, for one. They are building 3x300 MW furnaces on biomass, and are arranging for a 8 million T biomass supply from around the world. (By comparison, India's total biomass based power production - outside of bagasse power - is only about 1500 MW. So the Drax project alone would be about 60% of total Indian biomass installed capacity!) While I am certainly overawed, good news, I must say. If they can operate it sustainably for a few years, biomass power would have definitely reached a milestone. Will be really keen to know how they plan to manage the supply chain. This is what the news report has to say "The vast majority of the biomass will come from North America, but there will also be locally sourced supplies of willow and elephant grass to power the furnaces. "

A Case Study of Clenergen and Yuken’s Gasification Biomass Project

Yuken India Limited, set up in 1976 under a technical and financial collaboration with Yuken Kogyo Company Limited, Japan, is a manufacturer of oil hydraulic equipment. Yuken has achieved one of the fastest growth rates in the Indian oil hydraulics industry, in the last 29 years. Clenergen India Private Limited, a wholly owned subsidiary of Clenergen Corporation, plans to enter into a minimum 15 years Power Purchase Agreement (PPA) with Yuken to supply up to 2.5MW/h, with the rest of the electricity generated being completely sold out to the National Grid System. The biomass power plants with a capacity of 4 MW/h will be installed and begin operation within 10 months upon signing of the PPA. Clenergen India plans to lease up to 800 acres of non arable land near the manufacturing site in order to grow a high yielding species of bamboo as a source of biomass for the gasification power plant. The bamboo produced is asexual, non-invasive, non-flowering plant with a lifespan of up to 50 years and above all, is a product of tissue culture. This is advancement in the sector of renewable energy, in that the cost savings created from the cultivation of biomass feedstock will allow the supply of electricity at a price lower than the current market prices and will also help to extend the industries’ vertical market penetration into these market sectors. This is certainly moving forward. With ever increasing fossil fuel prices, this is the ideal way to deal with the growing needs and the economy.   Also check out: EAI Consulting for Bio-energy & Biofuels, Bioplastics & Other Biomass-based Value Added Products

Agricultural biomass availability in India for power generation

India is primarily an agricultural nation with an extensive cultivation of different types of crops including cereal, pulses, oilseeds, fibre crops, spices and plantation crops. With the cultivation of these crops, availability of residual biomass after economic harvest makes power generation in a sustainable way. These raw materials are normally available in variable quantities depending on the acreage of cultivation, mass of residue part available. The total biomass is 511,041 kT/Yr for power generation. Among them, rice, wheat and cotton constitute a major portion with 160,000,111,000 and 21,000 kT/Yr to generate power of 5000, 3300 and 3500 MW respectively. The total power generation capacity is 17,400 MW. Besides these crops, maize, jowar, bajra, coconut, groundnut, banana, cassava and mustard are also potent generators of biomass for power to an appreciable extent. It is evident from the information stated above that the agricultural resources serve as excellent candidates for the power generation either by combustion or gasification. However it is important to note that these materials are variables by biochemical composition and moisture. So, standardization is mandatory by defining limits to make them appropriate for thermal decomposition and as consistently yielding materials of electric power. Further plans are required to efficiently collect and store for processing without time delay.

Benefits of Biomass Based Power

While we are striving hard to switch to more sustainable modes of living, there arise lots of issues questioning the efficiency of our choice of green.  Despite all the issues they might have, they have more benefits than their petroleum counterpart. After all, petroleum is not going be here forever. So, this post will focus on the benefits of biomass based power, and why is it more suited as a sustainable alternative. Let us look at the distributed generation, because biomass is available in almost all places, and especially in rural areas, and more important, as gasification based power production can be done on small scales (as low as 20 kW), this process can be used for distributed generation of power as against the centralized power production method followed today. Also, biomass based power is well suited to remote villages with no access to grid but access to significant amounts of biomass Secondly, biomass gasification based power production can be done at small scales – as small as 20 kW – unlike other sources of power (say, nuclear) that require much larger scales. This will ideally suit small villages that have only a few households. Also, this whole process could be done in rural areas, where this could open a gateway of opportunities for rural population. Given that a 1 MW biomass based power generation could require biomass growth in over 150 hectares, the opportunities for rural employment are indeed significant. Thirdly, biomass power results in no new net GHG emissions as it is part of the carbon cycle. Unlike coal and others forms of fossil fuel which have been buried millions of years ago and burning them adds to carbon in the atmosphere, responsible biomass energy generation results in no new carbon emissions or pollution. Finally, the efficiency of the biomass power generation process to make use of mostly animal and crop wastes for energy is remarkable. Also, there is a large variety of feedstock which could be used for the process. Aside from these, they also significantly reduce methane in the atmosphere, which being able to be produced economically. I suppose these are enough reasons to switch to biomass power.

Biomass based power

Biomass is a valuable physical mass of biotic factors and ideally suited for the energy generation in different forms for the fulfillment of human demands over time. Even though deep ground fuel resources of biological origin satisfy it comprehensively, the way it is oxidized today on a time scale for energy production alarms the world by a phenomenon called “Global warming”. It forces us to scan for a suitable and sustainable alternative to fossilized biomass and the answer lies with surface dwelling, active biomass which is derived either from live or dead sources for power generation. Biomass can be subjected to power generation by combustion principle which is exactly followed for fossil sources and also is found to have a greater flexibility to generate power than conventional sources. Besides combustion, biomass is readily amenable for gasification where energy as power, heat and synthetic fuels can be derived. Biomass based power proves to be highly profitable under conditions where natural resources such as wood from forests, agricultural and animal sources etc are at abundance. India is a potential hub for this alternative route of power generation but currently holds a marginal fraction of 2650 MW out of its total installed capacity of 172000 MW. It utilizes bagasse co-generation system as its major option for biomass based power production with a capacity of 1411.53 MW achieved till June, 2010. It is important to note that biomass based power is multi-dimensionally advantageous as follows Rural economic upliftment, Suited for rural areas, Ability to have small kW scale power production, Distributed generation, Carbon neutral, Efficient utilization of renewable biological sources and accession of low cost resource.

Biomass Boilers Guide – Guide to Pick Optimal Biomass, Processing & Boiler Type

Many companies in India, and worldwide, are shifting from the use of fossil fuels for their boilers to using biomass. Such a transition is not easy though, given the significant differences between biomass and coal or other fossil fuels - differences both in terms of product characteristics as well as the supply chain and other market characteristics. So, how can a company go about making the key decisions in its transition to a biomass boiler? The nice folks at Boilers.Guide have put together a guide that eases this transition, specifically from coal to biomass boilers. This guide helps you iron out many of the uncertainties and questions a typical stakeholder has. The guide provides pointers on what characteristics to look for while selecting the optimal biomass to be used in boilers, selecting the right form (i.e pellets, briquettes, loose) for transportation and storage and selecting the appropriate combustion system and pollution control equipment. The guide is divided into three stages of selection with each stage providing information on the parameters to be considered, the pros and cons and examples to help you set up the most optimal biomass boiler.

Biomass conversion to natural gas – is this being followed anywhere?

I and my team might be working on an interesting project where the company is trying to move away from natural gas for its heating purposes and into the use of biomass for the same. The reason of course has to do with economics, with natural gas prices shooting through the roof past couple of years. While we are figuring out ways in which the company could use biomass directly for heating instead of natural gas, this process poses some problems owing to the specific needs of the client. I am hence wondering if the process of converting biomass to natural gas is being followed anywhere. I know that this is pretty much feasible, but not sure about the technology maturity and economics. If there is anyone who is aware of commercial conversions of biomass to natural gas, do let me know. You can include your response in the comment section or send a note to narsi [at] eai dot in. Thank you.

Biomass Gasification for the Environment and Economy

There are a whole lot of benefits from biomass gasification, both economy wise and ecology wise. Speaking of environmental benefits, gasification plants produce significantly lower quantities of air pollutants, which is really a good thing.  The process can also reduce the environmental impact of waste disposal because it can use waste products as feedstock, generating valuable products from materials that would otherwise be disposed as wastes. Gasification's byproducts are non-hazardous and are readily marketable and also use significantly less water than traditional coal-based power generation, and can be designed so they recycle their process water, discharging none into the surrounding environment. If that is not convincing, let us look at the economical benefits. Gasification can be used to turn lower-priced feedstocks into valuable products like electricity, substitute natural gas, fuels, chemicals, and fertilizers. For example, a chemical plant can gasify petcoke or high sulfur coal instead of using high-priced natural gas, thereby reducing its operating costs. While a gasification power plant is capital intensive (like any very large manufacturing plant), its operating costs are potentially lower than conventional processes or coal-fired plants because gasification plants are more efficient and require less back-end pollution control equipment. With continued research and development efforts and commercial operating experience, the cost of these units will continue to decrease. The process also offers wide fuel flexibility. A gasification plant can vary the mix of solid feedstocks, or run on gas or liquid feedstocks—giving it more freedom to adjust to the price and availability of its feedstocks. Many predict that coal-based power plants and other manufacturing facilities will be required to capture and store CO2, or participate in a carbon cap and trade market. In this scenario, gasification projects will have a cost advantage over conventional technologies.

Biomass Gasification in India to Generate Lakhs of Jobs

Emerging green economy in the country may see creation of nine lakh jobs in India by 2025, a top government official said.

"India could generate nine lakh jobs by 2025 in biomass gasification, of which three lakh would be in manufacturing of stoves and six lakh in areas such as processing into briquettes and pellets and the fuel supply chain," Ministry of Micro, Small and Medium Enterprises (MSME) Secretary Dinesh Rai said.

More from here.

I am not sure if biomass gasification alone could generate almost a million jobs. The secretary appears to have his numbers done for him all right, but I still wonder.

It will of course be good if it comes true. It was only yesterday that I met this gentleman whose company manufactures efficient burners for kerosene stoves and he was quite hopeful about the micro-gasifiers as well.

Let's see how it goes

Biomass Gasification Power Production – Bottlenecks and Barriers

Biomass gasification is a process where materials are transformed by thermal decomposition under partially oxygenated conditions to generate syn-gas for power generation. It seems to be a powerful technique where energy can be produced in a sustainable way along with valuable products such as green oil and biochar but it is multi step process where bottlenecks continuously arises at every step of the production pathway. The most commonly encountered limitations are batch to batch variation in  energy content, purification of the syngas, contaminants influence in the performance of the engines, ash and biochar disposals, toxic gas emissions and operational efficiency of the gas engines and mandatory modifications required to make the engines energy effective. In addition to these prime technical problems, others notable hindrances are insufficient capacity of the stakeholders and inadequate institutional and policy framework at the national, regional and local levels and limited access to financing and lack of interest on part of the state electricity boards (SEBs) in promoting biomass power generation etc. In India, conditions are further complicate by lack of working capital, limited interest in power projects, lack of effective regulatory framework and absence of effective information dissemination etc. In spite of the limitations, the technology continues to gain acceptance. Its potential to meet the energy demands on a flexible scale makes a robust move to outweigh the magnitude of limitations associated with it.

Cons of Gasifiers

The use of biomass gasification for power production is not new, but its use has been so far been limited and its contribution to the overall power production has so far been negligible in India. The producer gas derived from biomass gasification can be used for either producing power (by use in a gas engine) or can be used for thermal applications. With better technologies evolving for both gasifiers and gas engines, it can be expected that biomass gasification could start contributing a lot more to the overall power production in India. For starters, biomass gasifiers are reactors that heat biomass in a low-oxygen environment to produce a fuel gas called the producer gas. The gas produced from a gasifier can drive highly efficient devices such as gensets, turbines and fuel cells to generate electricity. A biomass gasification system consists primarily of a reactor or container into which fuel is fed along with a limited (less than stoichiometric, that required for complete combustion) supply of air. Heat for gasification is generated through partial combustion of the feed material. The resulting chemical breakdown of the fuel and internal reactions result in a combustible gas usually called producer gas. Though gasifiers are really special in their own way, they have their limitations. Gasification is a complex and sensitive process. There exists high level of disagreement about gasification among engineers, researchers, and manufacturers. Several manufacturers claim that their unit can be operated on all kinds of biomass. But it is a questionable fact as physical and chemical properties varies fuel to fuel. Gasifiers require atleast half an hour or more to start the process. Raw material is bulky and frequent refuelling is often required for continuous running of the system. Handling residues such as ash, tarry condensates is time consuming and dirty work. Driving with producer gas fueled vehicles requires much more and frequent attention than gasoline or diesel fueled vehlicles. Getting the producer gas is not difficult, but obtaining in the proper state is the challenging task. The physical and chemical properties of producer gas such as energy content, gas composition and impurities vary time to time. All the gasifiers have fairly strict requirements for fuel size, moisture and ash content. Inadequate fuel preparation is an important cause of technical problems with gasifiers. Gasifier is too often thought of as simple device that can generate a combustible gas from any biomass fuel. A hundred years of research has clearly shown that key to successful gasification is gasifier specifically designed for a particular type of fuel. Hence, biomass gasification technology requires hard work and tolerance. As I said, gasifiers are indeed special in their own way. I’d rather we just wait for the technology to advance in the future to go far beyond its limitations. After all, as I said then and I will again, petroleum is not here forever, and we need more sustainable feedstock and advanced technologies for processing.

Cool Solutions for Your Hot Problems – Getting Your Heating Costs Under Control

industrial heating boiler 1 Sustainable Industrial & Commercial Heating Solutions - A Critical Pain Point No, this blog post is not about those hot problems. It is about problems companies, especially in the manufacturing sector, face for their heating requirements! With the prices of furnace oil, diesel and LPG increasing alarmingly in the past few years, companies suddenly find their costs of their energy shooting up to unaffordable levels. Suddenly, using renewable and sustainable energy sources such as solar and biomass, and utilizing heat that was wasted earlier appear to be the way forward. I hence thought I’d provide an overview of renewable and sustainable options available for heating requirements in factories. The following are the sustainable heating avenues that are technically feasible today:

  • Solar Water Heater
  • Biomass
  • Waste Heat Recovery/CHP/Cogen
  • CST (concentrating solar thermal)
  • Energy efficiency heating equipment
  • Back pressure steam turbine
Solar Water Heaters Yes, we are talking about the simple and common solar water heaters. Could they provide a solution for industrial heating needs? The answer is Yes. Solar water heaters typically can provide temperatures up to only about 70OC, while many industries such as food and diary will require temperatures upwards of 150 deg C. This should however not be a deterrent as solar water heating can be used to preheat the water.  To the extent that solar water heaters can be used to replace furnace oil or diesel, proportionate cost savings can be derived. Taking the current prices of furnace oil, diesel, LPG or natural gas, even partial substitution of any of these fuels with solar heat makes significant economic sense. The capital cost involved in setting up this solar water heater facility can be recovered in about 2.5 years at the current prices of fossil fuels. Biomass based heating Let's consider a factory currently using about 10000 m3 of natural gas per day (or about 10,000 liters of furnace oil per day) for this discussion. Such a factory can save considerably by switching over to biomass from fossil fuels for its heating applications. The advantage with biomass based heating is that it is a firm source of energy and can technically replace the entire fossil fuel use for 24X7 operations. Biomass–based heating is a fairly old idea, but today, this can provide more bang for the buck using the gasifier technology which is a much more efficient way to provide heating than direct combustion. Essentially, combustion is not the best way to derive heat energy from biomass. Gasification, by first converting the biomass into an organic gas called the producer gas, makes the entire heating process far more efficient as it is easier to control and optimize producer gas for combustion than it is to optimize raw biomass. Using gasification also provides small amounts of charcoal as a by-product. Charcoal commands a good value in the marketplace. Today, a number of plants in India and overseas are seriously looking at using biomass for their boiler as well as their other heating and drying applications. The economics of biomass are fairly simple. At the current prices of biomass (Rs 4-5 per Kg), a 50 T per day biomass based gasification can displace about 10000 m3 of natural gas  or about 10,000 l of furnace oil. Natural gas costs about Rs 40 per m3 and furnace oil about Rs 42 per liter. Thus, biomass based heating would cost Rs 2.5 lacs per day vs Rs 4 lacs approx for either furnace oil or natural gas. This translates to a saving of Rs 1.5 lacs per day for such a facility or over Rs 5 crores per year!  The payback periods for these are in the range 2-3 years. Waste heat recovery / CHP / Cogen Utilization of waste heat has become one of the most sought after ways in the manufacturing sector today. With available technologies, it is today possible to convert both high temperature waste heat as well as low grade waste heat into useful heat or cooling. Of specific relevance here are technologies such as vapour absorption chilling, stirling engine and organic rankine cycle power generation mechanisms. While stirling engine is arguably not yet ready for large scale, reliable commercial use, vapour absorption chilling is a mature technology today, and organic rankine cycle is already a commercially available solution. VAM (vapour absorption) route will be especially useful for factories having significant cooling requirements, either in terms of air conditioning or for chilling/refrigeration. CHP/cogen is already quite prevalent in the sugar mills and distilleries in India. For those facilities that have large amounts of waste heat, CHP is a viable and financially rewarding option. Concentrating Solar Thermal Until a few years back concentrating solar heat was used predominantly for power generation – known as concentrating solar power (CSP). But today, using the same CSP technology as the base but with lesser sophistication, solutions are available that allow concentrating solar heat to generate steam up to 200OC, something that can be used in many process industries for most of their heating purposes. This has opened up the new domain of concentrating solar thermal (CST). CST is today a commercial solution and has already been adopted / implemented at many process industries in the country including diaries, food manufacturing units, large canteens and kitchens and the like. In most case, CST might not be able to replace conventional fuel use fully. It has however been estimated that it could replace up to 75% for many installations. That can be a tremendous saving for companies that are bearing the brunt of fast increasing furnace oil / LPG / diesel prices. Unlike solar water heaters, which is a highly mature technology, CST is still undergoing significant innovations, thus making it possible for companies to have high efficiency and high productivity technology installations in the near future. CST has been shown to have payback periods of less than 3 years in the installations that it is already operating in India. Energy Efficient Heating Equipment I recall a trip I made to a well-known hotel in Chennai where the chief engineer said said that by just replacing one old pump with a new, efficient one, they were able to reduce about 5% overall in electricity costs. This moral is true for many heating appliances and equipment too - be they boilers, furnaces, ovens or kilns. Of course, the decision is usually harder as the capital costs involved in changing over could be considerable, as these heating equipments will usually form the bulk of the cost of the overall heating system. Back-pressure Steam Turbine Back pressure steam turbines are not exactly for thermal efficiency or for reducing your heating costs, but I thought I’d include these here as they still provide a better bang for the buck from the heat generated. Back-pressure steam turbines essentially use the extra pressure and temperature that are inevitably present in the process steam to drive a small non-condensing turbine to generate power. The steam that leaves this back-pressure steam turbine goes on to do the useful work. As mentioned earlier, while it does not provide heat at a lower cost, it provides more value for the same amount of energy used for heating, by generating additional power from it. Summary There, you have it. Using one more of the above six avenues, factories that use significant amounts of heat can achieve significant cost savings while at the same time becoming far more “green” and environment friendly. Wish to know more on how your factory could be made more green through sustainable heating solutions? Send a note to me - Narasimhan Santhanam  ( narsi@eai.in  ).

Costs of feedstock for Biomass gasification

Biomass gasification utilizes renewable feed stocks for liberating the synthesis gas by thermal decomposition under high temperature conditions. Among the factors affecting the production protocol, cost economics play a critical role and is well pronounced in cases when the scale of operation is magnified. Entrepreneurs of gasification technology often make contracts with farmers or traders so as to ensure a price security and timely uninterrupted availability of their concerned feed commodity. In spite of the strategies, price fluctuations in gasification feed stocks have been witnessed, for instance cost of rice husk was at Rs: 600/tonne in 2009 but has steeply increased to Rs 1800/tonne by the end of 2010 and such an extreme volatility in market prices causes a concern to buyers and affect the final price of the power/unit produced by biomass gasification technology. Lack of price security has produced an unique trend in gasification where the venturers start their own farms for feed stock production which they claim that it can cut costs by two-third of the actual cost and seems to be working well in particular with dedicated energy crops. Gasification technology is well balanced economically as entrepreneurs have a scope to sell biochar by-product which fetches good market price to compensate for the cost procurement of the feedstock. Socio-economic and technical factors continuing to challenge the progression of gasification but the productivity makes it a superior choice that cannot be camouflaged.

Current Status of Biomass Gasification in India

India has initiated its power generation from renewable sources by several different principles namely gasification and combustion. Biomass gasification is carried out at different power capacity levels ranging from 25 kW to 2 MW and above. When a comparative analysis is made between combustion and gasification of biomass, the former technology is best operational under high capacity installations while the inverse is true for the gasification. This peculiar advantage seen in gasification to operate at smaller ranges makes the technology suitable for adoption in rural and by small entrepreneurs where power generation is required rather than efficiency. The technology even though best functions with high range installations of 2 MW, its utility is obstructed by the demand for a series for engines and India has less than 10 installations so far. Gasification technology is really ideal where resources are randomized and adoption of any other technology is tedious on a financial scale. Gasifiers are flexible to operate which makes the user to follow any technology depending on his requirements to a limited extent.

Decarbonizing India’s Energy Sector by Biomass and Biofuels


This post is a part of DIL Intelligence series from Energy Alternatives India (EAI), India's leading climate-tech consulting firm.

DIL stands for Decarbonization for India's Leaders and provides comprehensive market intelligence and updates to Indian corporate leaders on prominent decarbonization efforts across the Indian industrial ecosystem. DIL is provided by EAI's strategy consulting team. More about our consulting from here.


In India, 22% of the total energy supply is renewables, with biomass contributing 85%. Biomass use is shifting from traditional residential heating to power production. Biofuels represent less than 1% of transport fuels, with bioethanol at 3% of gasoline consumption. The biomass market is projected to reach INR 32,000 crore by FY2030-31. India produces 450-500 million tonnes of biomass annually, with a surplus of 230 MMT/year. Biomass-derived energy constitutes 32% of India’s primary energy use. The biomass pellet manufacturing capacity is 2.38 MMT, with 83,066 MT co-fired in 39 thermal power plants.

Reliance Industries Limited (RIL) is transitioning from fossil fuels to renewable energy, including biofuels, for its energy demand. This involves using bio-pathways to fix CO2 and recycling materials across value chains. RIL plans to set up around 100 Compressed Biogas (CBG) plants over the next five years, consuming over 5.5 million tonnes per annum of agricultural residue and organic waste. This initiative is projected to reduce nearly 2 million tonnes of carbon dioxide emissions annually. In essence, RIL’s decarbonization strategy involves renewable energy, biofuels, recycling, and CBG plants.

Thermax, an Indian energy and environment engineering company, is decarbonizing its manufacturing processes using biomass and biofuels. Its subsidiary, TOESL, installs biomass-fired plants and sells steam. Thermax’s solutions include the Atmospheric Fluidised Bed Combustion Boiler, capable of using various fuels including coal, lignite, rice husk, petcoke, spent coffee ground, washery rejects, low ash coal, paper sludge, roasted chaffs, DOB, bagasse, pith woodchips, coffee husks, mustard stalk, cotton stalk, and char. Thermax has secured an order worth over Rs 500 crore to set up five bio-CNG plants across India, with a capacity to produce 110 Tonnes Per Day of bio-CNG, utilizing local feedstock exceeding 1,000 TPD. This initiative contributes to the decarbonization of manufacturing processes.

The shift from fossil fuels to renewable energy sources is a key aspect of the company's strategies. This transition is driven by the need for cleaner energy sources and the potential economic benefits of renewable energy. Development of advanced biofuels like bioethanol, biodiesel, and biogas from sustainable feedstocks like algae and dedicated energy crops can further reduce reliance on fossil fuels and enhance energy security.

Looking ahead, the focus will be on enhancing the efficiency of biomass and biofuel technologies, developing second-generation bioconversion processes, and ensuring the sustainable sourcing of feedstocks. The potential of biomass and biofuels extends beyond just energy production. It opens up opportunities for waste management, rural development, and job creation, contributing to a circular economy. Companies like Reliance Industries and Thermax are pioneering this transition, demonstrating the viability and benefits of these renewable energy sources.

Emerging Feedstock for Biomass Power

Following my previous post on the industry perspectives on the various methods that have to be adopted for sustainable feedstock procurement (http://eai.in/blog/2011/12/industry-perspectives-and-strategies-for-effective-biomass-feedstock-procurement.html), today’s article showcases the various feedstock (emerging) that could be used as  a potential source for biomass-based power generation. As you might be well aware, the first generation feedstock such as sugars, starches from wheat, sorghum, sweet potato etc are not widely used for bioenergy production owing to the food-fuel conflicts. Similarly, even the second generation feedstock such as mustard are not being used in a big way for bioenergy production. These days, more focus is being thrown on the advanced feedstock such as the third-generation biofuels ( these seek to improve yields through improving the feedstocks themselves instead of the processes). These feedstocks include those sources that promise to generate greater than 500 gallons of oil per acre per year. Examples include palm oil and algae oil, rapeseed and jatropha oil, grasses (switchgrass, miscanthus), trees (willow), halophytes (saltwater plants). Provided are some details of the emerging biomass feedstock such as camelina, miscanthus and bamboo and their potential to perform as a bio-fuel. Miscanthus: Miscanthus, also known as Elephant grass can grow up to 3 meters high and it is native to tropical and sub-tropical regions of Africa and South Asia. Miscanthus is mentioned as a biofuel crop because of its relatively high dry matter yields across a range of environmental and soil conditions. The Miscanthus genotype most commonly recommended for biofuel production is a sterile hybrid (Miscanthus x giganteus) believed to be a M. sacchariflorus x M. sinensis hybrid. Miscanthus utilization in the biofuel industry is primarily for combustion in power plants – it has the desirable properties of low water and ash contents. Current research is focused on its potential as a biomass crop for direct combustion and for lignocellulosic conversion to ethanol. Giant miscanthus has been studied in the European Union and is now used commercially there for bedding, heat, and electricity generation. Most production currently occurs in England but also in Spain, Italy, Hungary, France, and Germany. Recently, Japan and China have taken renewed interest in this native species and started multiple research and commercialization projects. In the United States, research began at the University of Illinois at Urbana-Champaign in 2001 and has expanded rapidly to other U.S. universities. However there is currently little published information on giant miscanthus yields in the United States. Bamboo: Recently, bamboo has received increasing attention for producing biofuel because of its easy propagation, vigorous regeneration, fast growth, high productivity and quick maturity. Bamboo is an efficient user of land, and produces more biomass per unit area than most tree species. But the process of converting bamboo cellulose into liquid fuel is difficult to execute efficiently because of the extraordinary density of the plant.  However, new research from Mississippi State University hold clues for how scientists can learn to more easily break down bamboo, and thus more efficiently extract biofuels from all other cellulose sources using the bacteria from pandas’ waste. If the researchers are successful, the manufactured enzymes could be used in a new, much cheaper and more efficient process for converting bamboo and other woody plants into biofuels. Fuel properties and potential as a bio-fuel of different bamboo species:

Species Moisture content Density Ash content Energy content
% g/cm3 % MJ/Kg
B.pallida 44 0.61 1.91 18.63
B.tulda 37 0.65 1.92 18.61
D.asper 37 0.77 4.23 17.92
D.membranaceus 43 0.62 4.99 18.81
G.apus 35 0.76 2.00 18.14
Camelina Camelina, an oilseed, is a rotation crop for wheat that can be established on marginally productive land. It is an annual, short season plant. Biofuel from camelina is an ideal jet fuel substitute. Camelina has a number of advantages over its competitors, including using far less water, thus allowing it to be grown on marginal land, thereby not taking food acreage out of production. Furthermore camelina has a relatively short growing season of 80 to 100 days, requires no special equipment to harvest, and the silage remaining after processing can be fed to livestock and poultry, with the added side benefit of increasing their omega-3 production. Camelina is increasingly emerging as a prime biofuel source and thus attracts investment worldwide, as global demand for aviation fuel for passenger flights is now more than 40 billion gallons annually. In the earlier of this year, USDA announced two Biomass Crop Assistance Program (BCAP) project areas devoted to developing camelina as biofuel in several states, including Montana. USDA's Risk Management Agency (RMA) has also recently announced a new pilot program of insurance for camelina beginning with the 2012 crop year.

Future Feed-in-Tariff Trends for India – for Wind, Solar and Other Renewable Power Sources

It is an open secret that renewable power requires incentives - these usually are in the form of capital subsidies, tax incentives and most importantly, via feed in tariffs. It is a million dollar (make that Billion Dollar) question what the future of feed in tariffs will be for the mainstream renewable power sources. I picked up some resources on these. Wouldn't say they provide a peek into the future, but at least one of these try telling us how the government arrives at these numbers, so that will provide us with some clues.

 Most of us have come across the gobar gas – literally meaning gas from the cow. It is the same as what is called biogas. This is the gas that is released when bacteria feast on organic matter – typically human and animal feces – and release a gas that is about 50% methane. While biogas had predominantly been used earlier for heating purposes, its use for power production is also beginning to show a marked rise across the world, and in India too. How is power produced from biogas? The process is actually quite simple. Step 1 is generation of biogas. This is done typically using what are anaerobic called digesters. Animal (or human) waste is fed into the digester, where the microorganisms (called methanogenic bacteria) act upon it. Depending on the type of digester, it could take anywhere between 10 days to 15 days for the waste to have been "digested" by the bacteria and the release of biogas. The biogas thus produced can be used in IC engines specially devised for the use of biogas. These engines are similar in working principles to diesel engines and natural gas engines. These engines produce electricity from biogas. A bit of observation will lead us to easily understand why this concept will be of enormous interest to specific industry segments. Two segments stand out - industries that employ large numbers of animals and sewage treatment plants that treat human waste. Both these segments have started benefitting from this concept; as a result, we have a few STPs (sewage treatment plants) already generating power from the sludge generated (one of the STPs at Chennai, at a town called Nesapakkam, generates about 500 kW of power from the waste, and uses the power generated for all its electricity purposes). Some numbers will help understand the potential available for power generation from biogas. The cow population of India (about 225 million) alone generates about 800 million tons of wet dung which translates to about 150 million T of dry weight. 1 Kg of dry cow dung can generate about 1.2 kWh of electricity (it can generate the equivalent of about 4 kWh thermal). Thus, if all cow dung were converted to electricity, that would be 1.2*150*1000 million kWh = 180 TWh. India generated a total of 855 TWh in 2011-12. This implies that cow dung, if entirely converted to power, would have produced about 20% of total India's power! If the waste of other cattle and human waste were also taken into account, this could be about 30%. That is an awesome number. Of course, these data hide the actual difficulty in converting even a small portion of animal or human waste into electricity, owing to the infrastructural and social problems associated with these. All the same, waste -> biogas -> power is quite practical to a whole host of industries for whom such waste is available on premises. More information about waste to energy in general in the Indian context, is available from EAI's waste to energy resource section. Some of the following YouTube videos provide a more visual account of how to generate biogas from organic waste: Biogas from food waste - ARTI - http://www.youtube.com/watch?v=BGSl72xZHNk&feature=related Bio-gas from kitchen waste and bio mass - http://www.youtube.com/watch?v=uppVZGS7bYI&feature=related Biogas from Vegetarian Food Waste - http://www.youtube.com/watch?v=NZFrPZZIFTs&feature=related Biogas from Human Waste - http://www.youtube.com/watch?v=_m1nr2v5S8o And while on sewage, human waste and toilets, etc, a couple of interesting articles on things are emerging New toilet technology after 150 years of waste The seat of power - Better sewage treatment is the latest thing in clean energy Also check out: EAI Consulting for Bio-energy & Biofuels, Bioplastics & Other Biomass-based Value Added Products

How Punjab Will Benefit from All Its Agricultural Residue- A Case Study

Agricultural residues never go to waste. Not when they can be used for generating energy. In this context, the government of Punjab, India, plans to produce about 1,000 MW of green energy from livestock residues by 2015. When you think about it, this has huge economical and environmental benefits. In a region where large quantities of cattle manure become a major pollutant, this could be seen as an opportunity that could open a lot of doors. Aside livestock residues, the state also generates nearly 21 million tons of rice stalks and similar biomass plant wastes annually, which can all go into the production of green power. The state government is thus planning to make renewable resources as the source of their power to contribute 10% of its total energy production in the next five years. It is worthy to mention that Punjab already runs a biomethanation facility with a capacity of 1 MW, in a location close to Ludhiana. The facility uses methanogens (microbes that produce methane as a metabolic by-product) for the manufacture of methane gas. It currently uses 235 tons of cattle wastes to generate 18,000 kWh of electricity in addition to producing 45 tons of organic fertilizer every day. Also, the Punjab Energy Development Agency has developed 318 MW of green power projects, which includes the Ludhiana plant, till date. These projects comprise 37 MW of small hydro facilities, 28 MW of biomass power facilities, 250 MW of biomass co-generation facilities and 2 MW of solar projects. The agency also develops 132 MW of green power projects currently, which include 11 MW of hydropower, 100 MW of biomass co-generation and 20 MW of traditional biomass. If everything goes right and operational, the state will generate 700 MW of green power by 2012. That’s big! It is worthwhile to note that the planters are also getting an income of nearly RS. 4,000 per acre every year in the process of marketing agro wastes to biomass facilities.

Industry Perspectives and Strategies for Effective Biomass Feedstock Procurement

===========================================

Are you looking to get energy security for your company through reduction in the use of diesel, furnace oil, LPG and costly grid power? EAI can do a feasibility study for the use of solar PV & thermal, biomass for heat and power, waste heat recovery and energy efficiency to dramatically cut down fossil fuel use and reduce your energy bills. See EAI's SURE-FIRE offering for more.

 ===========================================

One of the most critical bottlenecks for biomass power plants is the supply chain bottlenecks that could result in non-availability of feedstock. A related problem is the volatility, or more precisely increase, in the feedstock price. Both these could render the project unviable. Highlighted in this article are some of the industrial perspectives in overcoming barriers for procuring a balanced feedstock supply. EAI’s research with industry experts suggest that there is no established biomass value chain that exists in India for the procurement and transportation of the biomass feedstock. Typically, the facility staffs  from a biomass gasification plant acquires biomass from several to dozens of small-scale biomass suppliers on a relatively informal, non contractual basis; although some have considered the use of aggregators, there is no data or proof available from the Indian biomass gasification companies that have engaged such a service as yet. The biomass procurement model that is typically followed in India is discussed below: Route #1 – Biomass Producer -->Transport Contractor --> Biomass Collection Centres (BCC’s) --> Power Producers The biomass producer i.e. the farmers/mill owners hands over the feedstock to a transport contractor who in turn delivers the feedstock to the biomass consumers or BCC’s. The BCC’s (managed by the biomass consumer) pay the farmers and the power producers collect the feedstock from these collection centres as and when required. At some instances, the farmers deliver the feedstock in the power producer’s facility and get directly paid for it. Route #2 - Biomass Producers --> Waste Processing Mills -->Biomass Power Producers For feedstock where further processing is required, the farmers/mill owners deposit the feedstock in waste processing mills. From the waste processing mills through a transport contractor the feedstock is deposited in the BCC’s or directly in the power producer’s facility. In some cases, especially in briquetting, the processing is done in the collection centres itself where a mobile briquetter is taken and the briquettes that are processed are directly delivered to the facility or collected by the power producers. Key Strategies to be Followed for Effective Biomass Feedstock Procurement EAI’s interactions with the industry reveal that the following strategies have to be adopted   in order to bring both the availability and price of biomass under control:
  • Security should be addressed by obtaining a written formal supply agreement with a reputable, local supplier. A five-year signed supply agreement with pricing and minimum volumes can go a long way in helping to secure necessary financing. A bioenergy project that is totally reliant on only one source of feedstock will be at risk, so two supply contracts are even better. This will also allow one to negotiate a better feedstock price, as the supplier will benefit from a long-term relationship and a guaranteed market. An interested lender needs to know that both the feedstock supplier and bioenergy processor are committed to the project.
  • It can be beneficial to hire an independent professional to verify one’s biomass supply projections and double-check that the feedstock supply is sustainable over the long term
  • Backward integration and own captive biomass source (one company, Orient Green Power, is even trying out a novel technique of going for energy plantations on their own wind farms)
  • According to the Washington based biomass supply company ‘Powerstock’, for a well-managed supply, an inclusive definition of biomass is needed. The company is also taking efforts to educate the public on the value of well-managed, productive forests.
  • The bottom line of feedstock security is composed of several aspects: grower relations, harvesting, marketing, equipment utilization, proprietary techniques and agricultural economics. Hence it's important to manage the entire process from seed to market.
  • The supply sector needs to make the transition from a residues-based approach to an integrated, dedicated feedstock supply system using energy crops, plus residues.

Potential for Biomass Power in India

Biomass based power generation is a choice of reality under the geographical regions where a sustainability exists in the flow of biologically raw materials for the production of power and India is one of the most notable universal giants for the production of biomass based power which can be best understood from the estimates of its biomass availability and the power produced from it. India has biomass production of 546 million tonnes per year from the agricultural sources alone to generate electricity at a capacity of 17,982 MW and its overall production of power from renewable sources stands at 34961 MWe in 2010.A calculated annual growth rate for the next decade realistically and optimistically is above 42,000 MWe and 48640 MWe respectively. The development of biomass based power is further enhanced by the Government regulatory policies by declaring duty exemptions’, tax breaks and financial incentives etc. The cost of producing electricity from biomass is affordable at Rs: 2.25-3.25 / kWh. In spite of all these attempts biomass based power generation is at its infant stage because of hindering factors such as feedstock availability, transportation, price volatility etc. India to emerge as a role model must utilize its renewable energy sources to a large extent, develop dedicated energy crops, establish end user market for co-products such as charcoal, biochar, activated carbon, and implement energy efficient technology for economically feasible power generation on a massive scale.

PRESPL Secures ₹4.1 Million Investment from Mitsui for Biomass Growth


This post is a part of Climate G2I Intelligence series from Energy Alternatives India (EAI), India's leading climate-tech consulting firm.

G2I stands for Gateway 2 India, and provides comprehensive market intelligence and go-to market assistance for International firms entering the Indian climate-tech market. More about Climate G2I from here


Mitsui, a leading Japanese conglomerate, has recently invested ₹4.1 million in Punjab Renewable Energy Systems Pvt. Ltd. (PRESPL), a company focused on collecting agricultural residues and converting them into biomass briquettes and pellets. This investment underscores the growing potential of the Indian biomass sector, which is expected to witness significant growth in the coming years.

The Indian biomass market is estimated to be valued at around ₹50,000 crore and is projected to reach ₹1,00,000 crore by 2025, driven by factors such as the Increasing demand for renewable energy, Growing awareness of environmental concerns, and  Supportive government policies.

The Indian biomass sector is also witnessing a surge in international collaborations, with several prominent companies entering the market through partnerships and alliances. For instance,  Aramco, a prominent oil and gas company, joins forces with ReNew Power, India's largest renewable energy company, to explore opportunities in developing and deploying low-carbon technologies, including biomass-based power solutions. This collaboration signifies the growing interest of leading energy giants in exploring cleaner alternatives. 

Additionally, Danish Biogas's collaboration with the Maharashtra Energy Development Agency (MEDA) brings together expertise in advanced biogas technologies with experience in promoting renewable energy and rural development in Maharashtra. This partnership contributes to a more sustainable waste management system through biogas generation..

These strategic partnerships are just a glimpse into the exciting developments propelling the Indian biomass sector forward. The government is also playing a crucial role in accelerating its growth through supportive initiatives like subsidies for setting up biomass power plants and briquette/pellet production units, promoting dedicated energy crops and efficient residue collection systems, and providing tax benefits for biomass projects. Investments in research and development are also being made to improve conversion technologies, optimize feedstock utilization, and develop cost-effective biomass solutions.

Navigating this complex ecosystem requires a comprehensive understanding of the key players involved. The Indian biomass value chain comprises various stakeholders, including biomass producers like farmers and forestry companies, collectors and aggregators responsible for managing feedstock collection and storage, processing and conversion companies that transform biomass into usable forms, original equipment manufacturers (OEMs) who create machinery for the sector, suppliers providing essential goods and services, power plants and industries utilizing biomass-based fuels, and government agencies responsible for regulation and promotion.

Beyond the core value chain, the adjacent value chain plays a crucial role in supporting the sector's growth. This includes financial institutions offering loans and investments for biomass projects, research institutions and universities engaged in R&D advancements, and non-governmental organizations (NGOs) promoting sustainable practices and advocating for policy changes.

Indigenization remains moderate to low currently, with reliance on imported technologies and equipment. However, government initiatives and rising demand are expected to gradually increase domestic capabilities in the coming years.

Primary Routes for Power from Biomass

The three primary routes for biomass to power are: Combustion, Gasification and Anaerobic Digestion. Combustion is easy to understand – instead of using coal or other fossil fuel, use biomass to produce steam that runs a turbine. Combustion of biomass for power could either be in the form of co-firing (when it is burned along with coal) or pure play biomass based combustion. In the case of gasification, the biomass is first gasified and this gas turn produces power in a gas engine. Anaerobic digestion is usually applied to biomass that typically have a high amount of water in them (anaerobic digestion is most used for treating organic waste such as kitchen waste and sewage waste into energy). Under this route, microorganisms act upon the organic matter present in the biomass under anaerobic (absence of air) and convert it into biogas. An emerging route for biomass based power is pyrolysis. In this, the biomass is rapidly heated to 450 - 600 °C in absence of air, and results in a bio-oil called the pyrolysis oil, which can in turn be used for firing the boilers. Typically, 50 - 75 % (by weight) of the feedstock is converted into pyrolysis oil. Pyrolysis as a method for power production is not well established currently in India or elsewhere in the world. Typically pyrolysis plants work well beyond 2 MW scale, while gasification plants work well until 2 MW scale, at the current technological progress. Thus, it can be said that pyrolysis takes off where gasification ends. Also check out: EAI Consulting for Bio-energy & Biofuels, Bioplastics & Other Biomass-based Value Added Products

Prominent biomass feedstock for gasification

Biomass for power generation by combustion or gasification is normally variable in its chemical composition of electron rich reactants, ash content, moisture, sulphur and nitrogen content etc. As a result, selection of the most convenient feedstock is an issue of debate. The degree and diversity of contaminants strongly influence the production and purification of synthesis gas in gasification while they tend to have a minimum effect in the combustion process. Independant of these disturbances virtually any raw material applied in power generation process should be a matter with potentials. In India, a vast array of feed stocks are utilized for power generation but the most wide ones are farm and mill wastes, woody trees, energy plantations and other green manure crops. Preference is made on the basis of availability, cost, bulkiness of the material, pre-processing, storage etc. Biomass used in India yields varying level of energy but it is also the gas engine and generators whose efficiency equivalently determine power generation.

REC Price Band Revised

The Central Electricity Regulatory Commission(CERC) has announced the floor and forbearance prices to be used for solar/non-solar projects from the FY 2012-13 upto 2016-17. The prices set are shown in the table below

Non Solar (Rs.) Solar (Rs.)
Prices (2012-2017) Current % Reduction Prices (2012-2017) Current % Reduction
Forbearance Price 3300 3900 15.38 13400 17000 21.18
Floor Price 1500 1500 0.00 9300 12000 22.50
Background Earlier, the CERC had proposed a few changes (refer table below) to be made to the REC prices and invited comments/suggestions on the same.
Non Solar (Rs.) Solar (Rs.)
Proposed Current % Reduction Proposed Current % Reduction
Forbearance Price 3480 3900 10.77 13690 17000 19.47
Floor Price 1400 1500 6.67 9880 12000 17.67
  The final prices to be enforced from April 2012 were arrived at after considering the comments/views of stakeholders and participants at the public hearing on the proposed floor and forbearance prices. As can be seen, the final prices decided upon are considerably lower than the earlier proposed prices. Analysis Financial feasibility studies of power plants under the REC mechanism almost always consider the floor price for calculating returns. With this in mind, the evaluation of REC for the primary renewable energy generation systems looks quite healthy.
  • Non-solar – the floor price remains unchanged. Thus biomass/wind generators are expected to get the same minium revenue as they have been getting earlier.
  • Solar – the floor price has seen a cut of about 23% from current levels. Although this might seem drastic, it is not likely to have a significant impact on solar power projects (refer section below).
  APPC – Non preferential tariff and REC CERC stipulates that for a project to be eligible under the REC mechanism, the power producer has to sign a PPA with the state utilities at a price equal to the APPC price. The APPC price for a state for a particular time period is determined by the State Electricity Regulatory Commissions(SERC). Looking at the current APPC prices in various states, a combination of REC and a PPA signed at APPC rates seems comparable with the preferential PPAs signed with the state utilities. For example,  let us consider a solar PV plant to be setup in Tamil Nadu where the APPC price for 2011-12 is Rs. 3.38/kWh. Under REC regulations, if a RE developer were to get the floor price for the solar REC, the income for the solar PV plant would be Rs. 12.68 /kWh (Rs. 3.38 + Rs.9.3). Another case is Rajasthan, which has a very high potential for solar PV – where the income would be Rs. 11.9 /kWh. In comparison, under the phase 1 (batch 1) of JNNSM, the average price settled on through the reverse bidding process was  about Rs. 12.5 per kWh. As can be seen, these prices are comparable to tariff set through reverse bidding under batch 1 of the JNNSM scheme. Prices can only go higher APPC prices are set based on the cost of power generation from fossil fuel based power plants. It is highly likely that this price would increase in the future due to the increase in fossil fuel prices and scarcity of supply. This ensures that the APPC prices would continue to increase for the foreseeable future, thus ensuring higher year on year returns under the REC mechanism provided the PPA signed with the state utilities has provisions for purchase at floating APPC prices rather than fixed price. The table below gives a comparison between preferential tariff (reverse bidding under JNNSM) and REC mechanism for a plant in Tamil Nadu. The following assumptions were made for the sake of calculations
  • Average bid price under phase 1 batch 2 of JNNSM could be around Rs. 12.5 /kWh(on the higher side)
  • APPC prices could rise by 15% annually (base price used is that of Tamil Nadu) - reasons for this were mentioned earlier.
  • REC price after 2016-17 period (i.e. from FY 2017-18 onwards) is reduced by 25%
 
Year 2012 2013 2014 2015 2016 2017 2018 2019 2020 2021
JNNSM Tariff (average) (Rs. per kWh) 12.5 12.5 12.5 12.5 12.5 12.5 12.5 12.5 12.5 12.5
APPC (Rs. per kWh) 3.38 3.89 4.38 5.04 5.38 6.19 6.38 7.34 7.38 8.49
REC (Rs. per kWh) 9.30 9.30 9.30 9.30 9.30 6.98 6.98 6.98 6.98 6.98
Total (Rs. per kWh) 12.68 13.19 13.68 14.34 14.68 13.16 13.36 14.31 14.36 15.46
REC mechanism's Incremental revenue over PPA(Rs. per kWh) 0.18 0.69 1.18 1.84 2.18 0.66 0.86 1.81 1.86 2.96

Table: REC vs preferential PPA for 10 years post 2012

As can be seen from the above table, the REC mechanism is quite comparable, if not better when compared to the assured tariff provided by NVVN over 10 years of operation of the solar powerplant. Overall, the REC mechanism can clearly drive the solar market, provided the Renewable Purchase Obligation (RPO) is strictly enforced by the various SERCs. The CERC release can be found here.   Also check out: EAI Consulting for Bio-energy & Biofuels, Bioplastics & Other Biomass-based Value Added Products

REC Trading – November 2011

The REC trading for the month of November concluded yesterday. Figures reveal that the trading has increased significantly both in volume of RECs traded as well as the price. In total 105,527 RECs were sold. Keeping with the trend of previous months, IEX had a higher share of the market with 96,154 (90%) RECs traded while PXIL saw trading of 9,373 (10%) certificates. The large volumes of trading indicate that the obligated entities are trying to fulfil their RPO as soon as possible as REC prices are showing an upward trend. The price of REC varied between the two exchanges - IEX and PXIL. Non-solar RECs closed with a price of Rs. 2,900 at IEX while the RECs sold at Rs. 2,800 at the PXIL. At the IEX, the prices have seen a 7% rise over those paid last month where the trading price was Rs. 2,700 per REC.

PXIL 51,199 9,373 2,800 0 - -
Total 308,777 105,527 - 43 - -
Interestingly, there are 43 buy bids for solar REC; this suggests that the solar REC market is gathering steam. This growing interest suggests that solar projects being planned based on REC may soon be bankable and we could see a trend in developers going for the REC mechanism during the interm period between now and the second phase of the National Solar Mission. Solar developers have another reason to rejoice as well as maintain a shrewd view on the Solar REC market. This month saw the accreditation of the first Solar project under the REC mechanims - an 8.5 MW solar project located at Jalgaon, Maharasthra developed by Jain Irrigation Systems. This project's viability has to be closely followed over the coming trading sessions as the REC certificates generated from the project slowly start coming up for sale. In total there are about 244 projects registered under REC with an aggregated capacity of 1551.92 MW (this excludes the lone solar project that recently got accredited). Conclusion The REC market continues to impress with higher sale prices and volumes. The REC prices are expected to rise over the coming months given the fact that there only 4 months left for RPO compliance. However, the price as such is expected to rise only gradually and not at the high rates seen over the year. The registration of a solar project under the REC mechanism might open the flood gates for more solar projects depending on the performance of the solar RECS. This could lead to a pradigm shift in the solar project development in India, which up until now has looked up to the state/central solar policies as the only source for project viability thereby reducing the cost of solar power in India and accelerating the road to grid parity.   Also check out: EAI Consulting for Bio-energy & Biofuels, Bioplastics & Other Biomass-based Value Added Products

REC Trading – September 2011

The REC trading for the month of September concluded recently. Trading figures reveal that the trading has increased significantly both in volume of RECs traded as well as the price. In total 46,362 RECs were sold. Keeping with the trend of previous months, IEX had a higher share of the market with 41,385 (89%) RECs traded while PXIL saw trading of 4,977 (11%) certificates. The large volumes of trading indicate that the obligated entities are trying to fulfil their RPO as soon as possible as REC prices are showing an upward trend. The most encouraging part of the trading was the price paid for each certificate. The price of REC grew to Rs. 2300 from Rs. 1800 last month.

Interestingly, there are 7 buy bids for solar REC; up from the lone buy bid last month, although this is promising, it highlights a serious issue. As with the previous months, there are no solar RECs available as no projects are registered under REC. This is a worrying trend and is going to put immense strain on the obligated entities to fulfil their solar RPO. The reasons for lack of solar projects registered under REC could include

  • Higher payback period for solar projects
  • REC prices guaranteed only up to 2016-17
  • A combination of the above two greatly reduces the bankability of solar projects
Conclusion The increase in REC trade volumes and price is very encouraging. It shows that the mechanism is a viable revenue route for developers who have not signed any preferential PPA. The demand for REC certificates is bound to keep increasing as more and more obligated entities try to fulfil their RPO in the short time span available. This is scheduled to push the REC price even further which in turn could lead to REC prices hitting their forebearance highs in the coming months. Finally more effort needs to be put in to ensure that there is sufficient supply of solar RECs in the market.

That concluded the 3rd edition of the Renewtech India conference. The 4th Renewtech India conference is scheduled for 16-18 February 2012 at the same venue – Bombay Exhibition Centre, Goregoan, Mumbai.

Rice husk used for power in one of India’s poorest states- A case Study

Whoever thought rice husk can generate power needs a medal! Considering how much rice husks go to waste in a country where rice is the staple food, it is comforting to know fossil fuels are not our only resort for power production. Thanks to Manoj Shinha, a renewable energy entrepreneur pioneered using discarded rice husks as biomass to provide energy to Bihar, one of India’s poorest states. Mr. Shinha along with his colleagues Gaynesh Pandey, Ratnesh Yadav and Charles W. Ransler developed Husk Power Systems to address the situation of poverty in their home state of Bihar. Many villages in India live off the grid in the darkness, this new advancement means that they need not depend on grid for electricity, rather generate their own clean, affordable electricity.The company generates and sells electricity for a price that is less than half of what the villagers pay for kerosene. This was possible because the whole concept is focused on research and development investment to simplify energy production and transmission, such as using bamboo instead of cement posts to install power lines.And, since communities no longer use kerosene, wood or dung for electricity, this way of electricity generation lowers the environmental and health hazards. In addition, rice husk ash, a byproduct of the gasification process, can be used for concrete production thus reducing the amount of high-carbon Portland restless leg syndrome cement.On average, a single power plant serves 400 houses, replacing 42,000 liters of kerosene and 18,000 liters of diesel yearly. As of August 2010, H.P.S. has sequestered 50,000 tons of carbon dioxide. Currently, they have installed over 60 mini-power plants that are 100 percent biomass-based which supply power to over 25,000 households in more than 250 villages.With the market opportunity in mind, they aim to expand their business to bring clean electricity to Indian villages by installing 2,000 new plants by 2014 beyond Bihar.

Tamil Nadu’s Biomass Power Plans – Energy Plantations is the Answer?

Biomass is one of the renewable energy domains in which Tamil Nadu could have significant potential for progress in future. Estimates suggest only about 10% of the potential has so far been utilized. Of course, the lack of a robust supply chain that make create supply and price security is a problem as much in Tamil Nadu as it is in the rest of the country. Some inputs and updates for biomass power in Tamil Nadu are provided below.

  • Potential for Biomass based power in Tamil Nadu is 1589.9 MW (1160 MW based on agricultural waste and 429.9 MW from forest and wasteland cultivation).
  • 22 biomass power plants with total installed capacity of 169 MW are in operation.
  • Ten biomass power plants with totaling to 120 MW, with over 80% plant load factor, have faced temporary shut downs owing to unviable tariff rates and increasing feedstock cost.
  • Biomass power producers association has approached Tamil Nadu Electricity Regulatory Commission (TNERC) with a request to revise the tariff and offer higher annual tariff escalation. The viable rate for operating biomass power plants in years to come would run beyond Rs 6.50/kWh, but the current tariff of Rs 4.5/kWh is in no way adequate to sustain the projects in the long run.
  • Tamil Nadu Energy Development Agency (TEDA), along with Tamil Nadu Biomass Power Producers Association, has been actively involved in promoting large scale energy plantations in marginal / waste land in the state with high potential crops.
  • The Tamil Nadu Biomass Power Producers Association suggests that energy plantation would not only serve to provide cheap and continuous feedstock supply for power plants, but it would also improve the quality of life of the rural population. Estimates suggest that a 10 mw biomass power plant can ensure livelihood of over 2,000 marginalised families. They can be employed in collection, transportation, cutting, chipping of biomass and cultivation of wasteland with energy plants like Juliflora, Bheema Bamboo etc.
So, it looks like Tamil Nadu is betting significantly on energy plantations for a viable biomass power sector. Let’s hope they have got it right. Also check out: EAI Consulting for Bio-energy & Biofuels, Bioplastics & Other Biomass-based Value Added Products

The man propelling the bio-energy movement in India – PRESPL

Welcoming Lt Col Monish Ahuja to CLIMAFIX SUMMIT 2022 - the 1st summit for Indian climate tech startups. I'm sure you have heard the saying, "Water, water everywhere, not a drop to drink" That applies quite well to the Indian agricultural residues as well. Hundreds of millions of tons of agro waste around the country, but very little available for the industries to use. And worse, a good portion gets burnt on the fields because the farmers do not know what to do with them. So where's the challenge? What is broken in this system? To a significant extent, logistics, or rather the lack of it. Securing and transporting millions of tons of agricultural waste from hundreds of thousands of farmers and transporting it reliably to end users is not rocket science. But it is systems science. Discipline science. Or patience science, if that term is more endearing to you. In EAI's decade long work in the bio-energy sector during which we consulted for dozens of clients including the likes of GSK (#Horlicks division, now part of Unilever), we have seen how unorganized the agro-waste supply has been, except for bagasse coming straight from large sugar mills and to a lesser extent saw dust from plywood factories. It is a complex challenge of logistics, societal & local traditions, and of course the omnipresent politics. The sector needed someone who could wade through all these, build an efficient system and evolve an organized biomass supply chain. Enter Lt Col Monish Ahuja. Army discipline, Systems thinking. Business acumen. These characteristics have helped him build Punjab Renewable Energy Systems Private Limited (PRESPL) into a force to reckon with countrywide in industrial biomass supply. PRESPL is today is one of the few organized players that has the ability to provide industrial decarbonization on scale through biomass, supplying thousands of tons of agro-waste based biomass every day to industries. I remember sitting with him in his office in Navi Mumbai a few years back when he patiently took me through the process by which he was building an effective front-end logistics system while also putting together a scalable digital back-end system. While coming out from the meeting, I thought - finally, here's someone who appears to be just what the doctor ordered for India's bio-energy sector. Since then, his company has - not surprisingly - grown and grown. Hats off to Monish, and we are proud to have him as one of the experts who will share his insights at the CLIMAFIX SUMMIT 2022, India's first climate startup summit, Nov 25 & 26, Chennai, organized by the Climate Startup Intelligence division CLIMAFIX of EAI (Energy Alternatives India) & Energy Consortium - IIT Madras Welcome Monish, and here's hoping you inspire more of your breed - and soon.

VC / PE Perspectives and Opinions on Biomass Power

Indian VCs have not really done a good amount of investing in cleantech. Cleantech perhaps  is not really a VC game as it is more of an engineering related discplie that does not offer the types of scalabilitiees that VCs desire or the exit periods. VCs also do not understand cleantech well enough to take calls. Many cleantech deals, especially in the power segment, are PPA based, with limited upsides, not typical VC games. Many cleantech and renewable energy startups require capital that is much higher than what VCs can typically offer to invest. Predictions for Cleantech VC in 2011 - Kachan & Co.'s Dallas Kachan looks at what 2011 will have in store for cleantech (http://alwayson.goingon.com/node/66783 ) Sustained worldwide venture capital investment will continue to cede importance to corporate and non-institutional capital. A return to early stage venture investments - predict a return to early stage venture capital investing in cleantech in 2011. Energy efficiency emerges as the clear rock star of cleantech. Biofuel investment could reach former highs. Recycling and mining will attract more investment. Natural gas emerges to threaten solar and wind for utility renewable power generation. China becomes the most important market for cleantech: if you're not selling in China, you won't matter. There is a significant amount of interest among PEs for investments in both traditional and renewable energy. PEs – not surprisingly – are not very keen on risky technology bets in renewable energy, but are OK with business model risks. Some of the PEs (such as IFC, ADB etc) are willing to take fairly long-term views (with over 10 year horizon). Investment sweet spot ( in terms of the quantum) varies from fund to fund, but obviously for most of the blue-chip, it is upwards of $50 million. PEs are well aware of the regulatory and societal bottlenecks that could arise in large-scale energy sector investing (especially for coal-based and large-hydro based sectors). Many PEs are clear that they wish to invest in businesses that can stand on their own revenues (even if takes a while) and are not keen on business plans that rely on getting bought out. Most every PE acknowledged that while they might not like coal, it is here to stay as the largest contributor to power for the foreseeable future. PE arms of organizations such as IFC and ADB, while not shutting out the option of investing in coal-based or natural gas based power plants, have a mandate to decrease their exposures to these “non-green” sectors. What a PE can bring to the table - Many private equity funds have been able to provide not just the financial support required but also strategic support and value-add for the firm’s growth. Disconnect in Valuation expectations - one of the issues faced by PE players while investing in cleantech companies is the disconnect in valuation expectations between the entrepreneur and investor with the buoyant public markets resulting in an increasing buoyancy in expectations! PEs feel that entrepreneurs should take a longer term view while setting their valuation expectations. Currently, 80% of infrastructure projects, and 46% of power projects, are funded by the banking system. So, PEs constitute only a small share of the infrastructure projects. While private equity folks could like IRRs of about 25%, power and infrastructure IRRs is only about 12%. Some private equity companies might wish to play a consolidator’s role as well where they consolidate a diverse portfolio of (say) energy companies such that they win even if 7/10 companies do well enough. Investors such as IFC have specialists/experts in every project to take care of social and environmental aspects. Private equity funds are interested in the macro factors (demand supply gap in electricity et al) as well strategic micro factors. One of the factors that seem to interest PEs is the method for companies to go diversified on green power that is having assets in wind, small hydro, biomass etc together, instead of betting just on one thing alone.

Why Biomass for Power Generation?

Biomass has been used as a source of energy right since mankind started its existence; In fact, one of the predominant energy sources today is biomass. Biomass as a source for power production is not entirely new either. Biomass has been used, in the place of coal, for steam generation at power plants, though in a limited way. Indeed, currently, the predominant method used for producing power using biomass still is the combustion route, At the same time, other processes, such as biomass gasification, which can work at much smaller scales and use the biomass more efficiently are emerging. The newer processes especially biomass gasification based power production, is relevant today especially in the Indian context mainly because of its potential to provide distributed power at rural level, especially for small remote villages that have good access to biomass but no access to grid power, and which require only small scale power production. Biomass based power is also relevant in the context of climate change and global warming as biomass based power production is net carbon neutral. The contribution of bioenergy to the total primary energy consumption in India is over 27% (Source: FAO). This is indeed the case for many other countries, because biomass is used in a significant way in rural areas in many countries. However, the contribution of biomass to power production is much smaller than this percentage – currently, biomass comprises only about 2650 MW of installed capacity, out of a total of 172000 MW of total electricity installed capacity in the country. Besides, biomass power has the following benefits- distributed generation, baseload power, ability to have small, kW scale power production, suited for rural areas and ideal for rural economic upliftment. I believe these are enough to justify why biomass is best suited for power production. Check out: EAI Consulting for Bio-energy & Biofuels, Bioplastics & Other Biomass-based Value Added Products

Costs of feedstock for Biomass gasification

Biomass gasification utilizes renewable feed stocks for liberating the synthesis gas by thermal decomposition under high temperature conditions. Among the factors affecting the production protocol, cost economics play a critical role and is well pronounced in cases...

A 900 MW Power Plant Running on Biomass? It Could be a Reality in Five Years!

I thought I was never going to see the day when a large power plant would run entirely on biomass. You can understand my pessimism when you are told that a MW of powerplant will require about 8000 T of biomass every year. A 300 MW power plant will hence require an awful 2.5 million T of biomass every year. That's a heck of a lot of, well, anything. Well, there are some courageous folks around the world. Drax in the UK, for one. They are building 3x300 MW furnaces on biomass, and are arranging for a 8 million T biomass supply from around the world. (By comparison, India's total biomass based power production - outside of bagasse power - is only about 1500 MW. So the Drax project alone would be about 60% of total Indian biomass installed capacity!) While I am certainly overawed, good news, I must say. If they can operate it sustainably for a few years, biomass power would have definitely reached a milestone. Will be really keen to know how they plan to manage the supply chain. This is what the news report has to say "The vast majority of the biomass will come from North America, but there will also be locally sourced supplies of willow and elephant grass to power the furnaces. "

A Case Study of Clenergen and Yuken’s Gasification Biomass Project

Yuken India Limited, set up in 1976 under a technical and financial collaboration with Yuken Kogyo Company Limited, Japan, is a manufacturer of oil hydraulic equipment. Yuken has achieved one of the fastest growth rates in the Indian oil hydraulics industry, in the last 29 years. Clenergen India Private Limited, a wholly owned subsidiary of Clenergen Corporation, plans to enter into a minimum 15 years Power Purchase Agreement (PPA) with Yuken to supply up to 2.5MW/h, with the rest of the electricity generated being completely sold out to the National Grid System. The biomass power plants with a capacity of 4 MW/h will be installed and begin operation within 10 months upon signing of the PPA. Clenergen India plans to lease up to 800 acres of non arable land near the manufacturing site in order to grow a high yielding species of bamboo as a source of biomass for the gasification power plant. The bamboo produced is asexual, non-invasive, non-flowering plant with a lifespan of up to 50 years and above all, is a product of tissue culture. This is advancement in the sector of renewable energy, in that the cost savings created from the cultivation of biomass feedstock will allow the supply of electricity at a price lower than the current market prices and will also help to extend the industries’ vertical market penetration into these market sectors. This is certainly moving forward. With ever increasing fossil fuel prices, this is the ideal way to deal with the growing needs and the economy.   Also check out: EAI Consulting for Bio-energy & Biofuels, Bioplastics & Other Biomass-based Value Added Products

Agricultural biomass availability in India for power generation

India is primarily an agricultural nation with an extensive cultivation of different types of crops including cereal, pulses, oilseeds, fibre crops, spices and plantation crops. With the cultivation of these crops, availability of residual biomass after economic harvest makes power generation in a sustainable way. These raw materials are normally available in variable quantities depending on the acreage of cultivation, mass of residue part available. The total biomass is 511,041 kT/Yr for power generation. Among them, rice, wheat and cotton constitute a major portion with 160,000,111,000 and 21,000 kT/Yr to generate power of 5000, 3300 and 3500 MW respectively. The total power generation capacity is 17,400 MW. Besides these crops, maize, jowar, bajra, coconut, groundnut, banana, cassava and mustard are also potent generators of biomass for power to an appreciable extent. It is evident from the information stated above that the agricultural resources serve as excellent candidates for the power generation either by combustion or gasification. However it is important to note that these materials are variables by biochemical composition and moisture. So, standardization is mandatory by defining limits to make them appropriate for thermal decomposition and as consistently yielding materials of electric power. Further plans are required to efficiently collect and store for processing without time delay.

Benefits of Biomass Based Power

While we are striving hard to switch to more sustainable modes of living, there arise lots of issues questioning the efficiency of our choice of green.  Despite all the issues they might have, they have more benefits than their petroleum counterpart. After all, petroleum is not going be here forever. So, this post will focus on the benefits of biomass based power, and why is it more suited as a sustainable alternative. Let us look at the distributed generation, because biomass is available in almost all places, and especially in rural areas, and more important, as gasification based power production can be done on small scales (as low as 20 kW), this process can be used for distributed generation of power as against the centralized power production method followed today. Also, biomass based power is well suited to remote villages with no access to grid but access to significant amounts of biomass Secondly, biomass gasification based power production can be done at small scales – as small as 20 kW – unlike other sources of power (say, nuclear) that require much larger scales. This will ideally suit small villages that have only a few households. Also, this whole process could be done in rural areas, where this could open a gateway of opportunities for rural population. Given that a 1 MW biomass based power generation could require biomass growth in over 150 hectares, the opportunities for rural employment are indeed significant. Thirdly, biomass power results in no new net GHG emissions as it is part of the carbon cycle. Unlike coal and others forms of fossil fuel which have been buried millions of years ago and burning them adds to carbon in the atmosphere, responsible biomass energy generation results in no new carbon emissions or pollution. Finally, the efficiency of the biomass power generation process to make use of mostly animal and crop wastes for energy is remarkable. Also, there is a large variety of feedstock which could be used for the process. Aside from these, they also significantly reduce methane in the atmosphere, which being able to be produced economically. I suppose these are enough reasons to switch to biomass power.

Biomass based power

Biomass is a valuable physical mass of biotic factors and ideally suited for the energy generation in different forms for the fulfillment of human demands over time. Even though deep ground fuel resources of biological origin satisfy it comprehensively, the way it is oxidized today on a time scale for energy production alarms the world by a phenomenon called “Global warming”. It forces us to scan for a suitable and sustainable alternative to fossilized biomass and the answer lies with surface dwelling, active biomass which is derived either from live or dead sources for power generation. Biomass can be subjected to power generation by combustion principle which is exactly followed for fossil sources and also is found to have a greater flexibility to generate power than conventional sources. Besides combustion, biomass is readily amenable for gasification where energy as power, heat and synthetic fuels can be derived. Biomass based power proves to be highly profitable under conditions where natural resources such as wood from forests, agricultural and animal sources etc are at abundance. India is a potential hub for this alternative route of power generation but currently holds a marginal fraction of 2650 MW out of its total installed capacity of 172000 MW. It utilizes bagasse co-generation system as its major option for biomass based power production with a capacity of 1411.53 MW achieved till June, 2010. It is important to note that biomass based power is multi-dimensionally advantageous as follows Rural economic upliftment, Suited for rural areas, Ability to have small kW scale power production, Distributed generation, Carbon neutral, Efficient utilization of renewable biological sources and accession of low cost resource.

Biomass conversion to natural gas – is this being followed anywhere?

I and my team might be working on an interesting project where the company is trying to move away from natural gas for its heating purposes and into the use of biomass for the same. The reason of course has to do with economics, with natural gas prices shooting through the roof past couple of years. While we are figuring out ways in which the company could use biomass directly for heating instead of natural gas, this process poses some problems owing to the specific needs of the client. I am hence wondering if the process of converting biomass to natural gas is being followed anywhere. I know that this is pretty much feasible, but not sure about the technology maturity and economics. If there is anyone who is aware of commercial conversions of biomass to natural gas, do let me know. You can include your response in the comment section or send a note to narsi [at] eai dot in. Thank you.

Biomass Gasification for the Environment and Economy

There are a whole lot of benefits from biomass gasification, both economy wise and ecology wise. Speaking of environmental benefits, gasification plants produce significantly lower quantities of air pollutants, which is really a good thing.  The process can also reduce the environmental impact of waste disposal because it can use waste products as feedstock, generating valuable products from materials that would otherwise be disposed as wastes. Gasification's byproducts are non-hazardous and are readily marketable and also use significantly less water than traditional coal-based power generation, and can be designed so they recycle their process water, discharging none into the surrounding environment. If that is not convincing, let us look at the economical benefits. Gasification can be used to turn lower-priced feedstocks into valuable products like electricity, substitute natural gas, fuels, chemicals, and fertilizers. For example, a chemical plant can gasify petcoke or high sulfur coal instead of using high-priced natural gas, thereby reducing its operating costs. While a gasification power plant is capital intensive (like any very large manufacturing plant), its operating costs are potentially lower than conventional processes or coal-fired plants because gasification plants are more efficient and require less back-end pollution control equipment. With continued research and development efforts and commercial operating experience, the cost of these units will continue to decrease. The process also offers wide fuel flexibility. A gasification plant can vary the mix of solid feedstocks, or run on gas or liquid feedstocks—giving it more freedom to adjust to the price and availability of its feedstocks. Many predict that coal-based power plants and other manufacturing facilities will be required to capture and store CO2, or participate in a carbon cap and trade market. In this scenario, gasification projects will have a cost advantage over conventional technologies.

Biomass Gasification in India to Generate Lakhs of Jobs

Emerging green economy in the country may see creation of nine lakh jobs in India by 2025, a top government official said.

"India could generate nine lakh jobs by 2025 in biomass gasification, of which three lakh would be in manufacturing of stoves and six lakh in areas such as processing into briquettes and pellets and the fuel supply chain," Ministry of Micro, Small and Medium Enterprises (MSME) Secretary Dinesh Rai said.

More from here.

I am not sure if biomass gasification alone could generate almost a million jobs. The secretary appears to have his numbers done for him all right, but I still wonder.

It will of course be good if it comes true. It was only yesterday that I met this gentleman whose company manufactures efficient burners for kerosene stoves and he was quite hopeful about the micro-gasifiers as well.

Let's see how it goes

Biomass Gasification Power Production – Bottlenecks and Barriers

Biomass gasification is a process where materials are transformed by thermal decomposition under partially oxygenated conditions to generate syn-gas for power generation. It seems to be a powerful technique where energy can be produced in a sustainable way along with valuable products such as green oil and biochar but it is multi step process where bottlenecks continuously arises at every step of the production pathway. The most commonly encountered limitations are batch to batch variation in  energy content, purification of the syngas, contaminants influence in the performance of the engines, ash and biochar disposals, toxic gas emissions and operational efficiency of the gas engines and mandatory modifications required to make the engines energy effective. In addition to these prime technical problems, others notable hindrances are insufficient capacity of the stakeholders and inadequate institutional and policy framework at the national, regional and local levels and limited access to financing and lack of interest on part of the state electricity boards (SEBs) in promoting biomass power generation etc. In India, conditions are further complicate by lack of working capital, limited interest in power projects, lack of effective regulatory framework and absence of effective information dissemination etc. In spite of the limitations, the technology continues to gain acceptance. Its potential to meet the energy demands on a flexible scale makes a robust move to outweigh the magnitude of limitations associated with it.

Cons of Gasifiers

The use of biomass gasification for power production is not new, but its use has been so far been limited and its contribution to the overall power production has so far been negligible in India. The producer gas derived from biomass gasification can be used for either producing power (by use in a gas engine) or can be used for thermal applications. With better technologies evolving for both gasifiers and gas engines, it can be expected that biomass gasification could start contributing a lot more to the overall power production in India. For starters, biomass gasifiers are reactors that heat biomass in a low-oxygen environment to produce a fuel gas called the producer gas. The gas produced from a gasifier can drive highly efficient devices such as gensets, turbines and fuel cells to generate electricity. A biomass gasification system consists primarily of a reactor or container into which fuel is fed along with a limited (less than stoichiometric, that required for complete combustion) supply of air. Heat for gasification is generated through partial combustion of the feed material. The resulting chemical breakdown of the fuel and internal reactions result in a combustible gas usually called producer gas. Though gasifiers are really special in their own way, they have their limitations. Gasification is a complex and sensitive process. There exists high level of disagreement about gasification among engineers, researchers, and manufacturers. Several manufacturers claim that their unit can be operated on all kinds of biomass. But it is a questionable fact as physical and chemical properties varies fuel to fuel. Gasifiers require atleast half an hour or more to start the process. Raw material is bulky and frequent refuelling is often required for continuous running of the system. Handling residues such as ash, tarry condensates is time consuming and dirty work. Driving with producer gas fueled vehicles requires much more and frequent attention than gasoline or diesel fueled vehlicles. Getting the producer gas is not difficult, but obtaining in the proper state is the challenging task. The physical and chemical properties of producer gas such as energy content, gas composition and impurities vary time to time. All the gasifiers have fairly strict requirements for fuel size, moisture and ash content. Inadequate fuel preparation is an important cause of technical problems with gasifiers. Gasifier is too often thought of as simple device that can generate a combustible gas from any biomass fuel. A hundred years of research has clearly shown that key to successful gasification is gasifier specifically designed for a particular type of fuel. Hence, biomass gasification technology requires hard work and tolerance. As I said, gasifiers are indeed special in their own way. I’d rather we just wait for the technology to advance in the future to go far beyond its limitations. After all, as I said then and I will again, petroleum is not here forever, and we need more sustainable feedstock and advanced technologies for processing.

Cool Solutions for Your Hot Problems – Getting Your Heating Costs Under Control

industrial heating boiler 1 Sustainable Industrial & Commercial Heating Solutions - A Critical Pain Point No, this blog post is not about those hot problems. It is about problems companies, especially in the manufacturing sector, face for their heating requirements! With the prices of furnace oil, diesel and LPG increasing alarmingly in the past few years, companies suddenly find their costs of their energy shooting up to unaffordable levels. Suddenly, using renewable and sustainable energy sources such as solar and biomass, and utilizing heat that was wasted earlier appear to be the way forward. I hence thought I’d provide an overview of renewable and sustainable options available for heating requirements in factories. The following are the sustainable heating avenues that are technically feasible today:

  • Solar Water Heater
  • Biomass
  • Waste Heat Recovery/CHP/Cogen
  • CST (concentrating solar thermal)
  • Energy efficiency heating equipment
  • Back pressure steam turbine
Solar Water Heaters Yes, we are talking about the simple and common solar water heaters. Could they provide a solution for industrial heating needs? The answer is Yes. Solar water heaters typically can provide temperatures up to only about 70OC, while many industries such as food and diary will require temperatures upwards of 150 deg C. This should however not be a deterrent as solar water heating can be used to preheat the water.  To the extent that solar water heaters can be used to replace furnace oil or diesel, proportionate cost savings can be derived. Taking the current prices of furnace oil, diesel, LPG or natural gas, even partial substitution of any of these fuels with solar heat makes significant economic sense. The capital cost involved in setting up this solar water heater facility can be recovered in about 2.5 years at the current prices of fossil fuels. Biomass based heating Let's consider a factory currently using about 10000 m3 of natural gas per day (or about 10,000 liters of furnace oil per day) for this discussion. Such a factory can save considerably by switching over to biomass from fossil fuels for its heating applications. The advantage with biomass based heating is that it is a firm source of energy and can technically replace the entire fossil fuel use for 24X7 operations. Biomass–based heating is a fairly old idea, but today, this can provide more bang for the buck using the gasifier technology which is a much more efficient way to provide heating than direct combustion. Essentially, combustion is not the best way to derive heat energy from biomass. Gasification, by first converting the biomass into an organic gas called the producer gas, makes the entire heating process far more efficient as it is easier to control and optimize producer gas for combustion than it is to optimize raw biomass. Using gasification also provides small amounts of charcoal as a by-product. Charcoal commands a good value in the marketplace. Today, a number of plants in India and overseas are seriously looking at using biomass for their boiler as well as their other heating and drying applications. The economics of biomass are fairly simple. At the current prices of biomass (Rs 4-5 per Kg), a 50 T per day biomass based gasification can displace about 10000 m3 of natural gas  or about 10,000 l of furnace oil. Natural gas costs about Rs 40 per m3 and furnace oil about Rs 42 per liter. Thus, biomass based heating would cost Rs 2.5 lacs per day vs Rs 4 lacs approx for either furnace oil or natural gas. This translates to a saving of Rs 1.5 lacs per day for such a facility or over Rs 5 crores per year!  The payback periods for these are in the range 2-3 years. Waste heat recovery / CHP / Cogen Utilization of waste heat has become one of the most sought after ways in the manufacturing sector today. With available technologies, it is today possible to convert both high temperature waste heat as well as low grade waste heat into useful heat or cooling. Of specific relevance here are technologies such as vapour absorption chilling, stirling engine and organic rankine cycle power generation mechanisms. While stirling engine is arguably not yet ready for large scale, reliable commercial use, vapour absorption chilling is a mature technology today, and organic rankine cycle is already a commercially available solution. VAM (vapour absorption) route will be especially useful for factories having significant cooling requirements, either in terms of air conditioning or for chilling/refrigeration. CHP/cogen is already quite prevalent in the sugar mills and distilleries in India. For those facilities that have large amounts of waste heat, CHP is a viable and financially rewarding option. Concentrating Solar Thermal Until a few years back concentrating solar heat was used predominantly for power generation – known as concentrating solar power (CSP). But today, using the same CSP technology as the base but with lesser sophistication, solutions are available that allow concentrating solar heat to generate steam up to 200OC, something that can be used in many process industries for most of their heating purposes. This has opened up the new domain of concentrating solar thermal (CST). CST is today a commercial solution and has already been adopted / implemented at many process industries in the country including diaries, food manufacturing units, large canteens and kitchens and the like. In most case, CST might not be able to replace conventional fuel use fully. It has however been estimated that it could replace up to 75% for many installations. That can be a tremendous saving for companies that are bearing the brunt of fast increasing furnace oil / LPG / diesel prices. Unlike solar water heaters, which is a highly mature technology, CST is still undergoing significant innovations, thus making it possible for companies to have high efficiency and high productivity technology installations in the near future. CST has been shown to have payback periods of less than 3 years in the installations that it is already operating in India. Energy Efficient Heating Equipment I recall a trip I made to a well-known hotel in Chennai where the chief engineer said said that by just replacing one old pump with a new, efficient one, they were able to reduce about 5% overall in electricity costs. This moral is true for many heating appliances and equipment too - be they boilers, furnaces, ovens or kilns. Of course, the decision is usually harder as the capital costs involved in changing over could be considerable, as these heating equipments will usually form the bulk of the cost of the overall heating system. Back-pressure Steam Turbine Back pressure steam turbines are not exactly for thermal efficiency or for reducing your heating costs, but I thought I’d include these here as they still provide a better bang for the buck from the heat generated. Back-pressure steam turbines essentially use the extra pressure and temperature that are inevitably present in the process steam to drive a small non-condensing turbine to generate power. The steam that leaves this back-pressure steam turbine goes on to do the useful work. As mentioned earlier, while it does not provide heat at a lower cost, it provides more value for the same amount of energy used for heating, by generating additional power from it. Summary There, you have it. Using one more of the above six avenues, factories that use significant amounts of heat can achieve significant cost savings while at the same time becoming far more “green” and environment friendly. Wish to know more on how your factory could be made more green through sustainable heating solutions? Send a note to me - Narasimhan Santhanam  ( narsi@eai.in  ).

Costs of feedstock for Biomass gasification

Biomass gasification utilizes renewable feed stocks for liberating the synthesis gas by thermal decomposition under high temperature conditions. Among the factors affecting the production protocol, cost economics play a critical role and is well pronounced in cases when the scale of operation is magnified. Entrepreneurs of gasification technology often make contracts with farmers or traders so as to ensure a price security and timely uninterrupted availability of their concerned feed commodity. In spite of the strategies, price fluctuations in gasification feed stocks have been witnessed, for instance cost of rice husk was at Rs: 600/tonne in 2009 but has steeply increased to Rs 1800/tonne by the end of 2010 and such an extreme volatility in market prices causes a concern to buyers and affect the final price of the power/unit produced by biomass gasification technology. Lack of price security has produced an unique trend in gasification where the venturers start their own farms for feed stock production which they claim that it can cut costs by two-third of the actual cost and seems to be working well in particular with dedicated energy crops. Gasification technology is well balanced economically as entrepreneurs have a scope to sell biochar by-product which fetches good market price to compensate for the cost procurement of the feedstock. Socio-economic and technical factors continuing to challenge the progression of gasification but the productivity makes it a superior choice that cannot be camouflaged.

Current Status of Biomass Gasification in India

India has initiated its power generation from renewable sources by several different principles namely gasification and combustion. Biomass gasification is carried out at different power capacity levels ranging from 25 kW to 2 MW and above. When a comparative analysis is made between combustion and gasification of biomass, the former technology is best operational under high capacity installations while the inverse is true for the gasification. This peculiar advantage seen in gasification to operate at smaller ranges makes the technology suitable for adoption in rural and by small entrepreneurs where power generation is required rather than efficiency. The technology even though best functions with high range installations of 2 MW, its utility is obstructed by the demand for a series for engines and India has less than 10 installations so far. Gasification technology is really ideal where resources are randomized and adoption of any other technology is tedious on a financial scale. Gasifiers are flexible to operate which makes the user to follow any technology depending on his requirements to a limited extent.

Decarbonizing India’s Energy Sector by Biomass and Biofuels


This post is a part of DIL Intelligence series from Energy Alternatives India (EAI), India's leading climate-tech consulting firm.

DIL stands for Decarbonization for India's Leaders and provides comprehensive market intelligence and updates to Indian corporate leaders on prominent decarbonization efforts across the Indian industrial ecosystem. DIL is provided by EAI's strategy consulting team. More about our consulting from here.


In India, 22% of the total energy supply is renewables, with biomass contributing 85%. Biomass use is shifting from traditional residential heating to power production. Biofuels represent less than 1% of transport fuels, with bioethanol at 3% of gasoline consumption. The biomass market is projected to reach INR 32,000 crore by FY2030-31. India produces 450-500 million tonnes of biomass annually, with a surplus of 230 MMT/year. Biomass-derived energy constitutes 32% of India’s primary energy use. The biomass pellet manufacturing capacity is 2.38 MMT, with 83,066 MT co-fired in 39 thermal power plants.

Reliance Industries Limited (RIL) is transitioning from fossil fuels to renewable energy, including biofuels, for its energy demand. This involves using bio-pathways to fix CO2 and recycling materials across value chains. RIL plans to set up around 100 Compressed Biogas (CBG) plants over the next five years, consuming over 5.5 million tonnes per annum of agricultural residue and organic waste. This initiative is projected to reduce nearly 2 million tonnes of carbon dioxide emissions annually. In essence, RIL’s decarbonization strategy involves renewable energy, biofuels, recycling, and CBG plants.

Thermax, an Indian energy and environment engineering company, is decarbonizing its manufacturing processes using biomass and biofuels. Its subsidiary, TOESL, installs biomass-fired plants and sells steam. Thermax’s solutions include the Atmospheric Fluidised Bed Combustion Boiler, capable of using various fuels including coal, lignite, rice husk, petcoke, spent coffee ground, washery rejects, low ash coal, paper sludge, roasted chaffs, DOB, bagasse, pith woodchips, coffee husks, mustard stalk, cotton stalk, and char. Thermax has secured an order worth over Rs 500 crore to set up five bio-CNG plants across India, with a capacity to produce 110 Tonnes Per Day of bio-CNG, utilizing local feedstock exceeding 1,000 TPD. This initiative contributes to the decarbonization of manufacturing processes.

The shift from fossil fuels to renewable energy sources is a key aspect of the company's strategies. This transition is driven by the need for cleaner energy sources and the potential economic benefits of renewable energy. Development of advanced biofuels like bioethanol, biodiesel, and biogas from sustainable feedstocks like algae and dedicated energy crops can further reduce reliance on fossil fuels and enhance energy security.

Looking ahead, the focus will be on enhancing the efficiency of biomass and biofuel technologies, developing second-generation bioconversion processes, and ensuring the sustainable sourcing of feedstocks. The potential of biomass and biofuels extends beyond just energy production. It opens up opportunities for waste management, rural development, and job creation, contributing to a circular economy. Companies like Reliance Industries and Thermax are pioneering this transition, demonstrating the viability and benefits of these renewable energy sources.

Emerging Feedstock for Biomass Power

Following my previous post on the industry perspectives on the various methods that have to be adopted for sustainable feedstock procurement (http://eai.in/blog/2011/12/industry-perspectives-and-strategies-for-effective-biomass-feedstock-procurement.html), today’s article showcases the various feedstock (emerging) that could be used as  a potential source for biomass-based power generation. As you might be well aware, the first generation feedstock such as sugars, starches from wheat, sorghum, sweet potato etc are not widely used for bioenergy production owing to the food-fuel conflicts. Similarly, even the second generation feedstock such as mustard are not being used in a big way for bioenergy production. These days, more focus is being thrown on the advanced feedstock such as the third-generation biofuels ( these seek to improve yields through improving the feedstocks themselves instead of the processes). These feedstocks include those sources that promise to generate greater than 500 gallons of oil per acre per year. Examples include palm oil and algae oil, rapeseed and jatropha oil, grasses (switchgrass, miscanthus), trees (willow), halophytes (saltwater plants). Provided are some details of the emerging biomass feedstock such as camelina, miscanthus and bamboo and their potential to perform as a bio-fuel. Miscanthus: Miscanthus, also known as Elephant grass can grow up to 3 meters high and it is native to tropical and sub-tropical regions of Africa and South Asia. Miscanthus is mentioned as a biofuel crop because of its relatively high dry matter yields across a range of environmental and soil conditions. The Miscanthus genotype most commonly recommended for biofuel production is a sterile hybrid (Miscanthus x giganteus) believed to be a M. sacchariflorus x M. sinensis hybrid. Miscanthus utilization in the biofuel industry is primarily for combustion in power plants – it has the desirable properties of low water and ash contents. Current research is focused on its potential as a biomass crop for direct combustion and for lignocellulosic conversion to ethanol. Giant miscanthus has been studied in the European Union and is now used commercially there for bedding, heat, and electricity generation. Most production currently occurs in England but also in Spain, Italy, Hungary, France, and Germany. Recently, Japan and China have taken renewed interest in this native species and started multiple research and commercialization projects. In the United States, research began at the University of Illinois at Urbana-Champaign in 2001 and has expanded rapidly to other U.S. universities. However there is currently little published information on giant miscanthus yields in the United States. Bamboo: Recently, bamboo has received increasing attention for producing biofuel because of its easy propagation, vigorous regeneration, fast growth, high productivity and quick maturity. Bamboo is an efficient user of land, and produces more biomass per unit area than most tree species. But the process of converting bamboo cellulose into liquid fuel is difficult to execute efficiently because of the extraordinary density of the plant.  However, new research from Mississippi State University hold clues for how scientists can learn to more easily break down bamboo, and thus more efficiently extract biofuels from all other cellulose sources using the bacteria from pandas’ waste. If the researchers are successful, the manufactured enzymes could be used in a new, much cheaper and more efficient process for converting bamboo and other woody plants into biofuels. Fuel properties and potential as a bio-fuel of different bamboo species:

Species Moisture content Density Ash content Energy content
% g/cm3 % MJ/Kg
B.pallida 44 0.61 1.91 18.63
B.tulda 37 0.65 1.92 18.61
D.asper 37 0.77 4.23 17.92
D.membranaceus 43 0.62 4.99 18.81
G.apus 35 0.76 2.00 18.14
Camelina Camelina, an oilseed, is a rotation crop for wheat that can be established on marginally productive land. It is an annual, short season plant. Biofuel from camelina is an ideal jet fuel substitute. Camelina has a number of advantages over its competitors, including using far less water, thus allowing it to be grown on marginal land, thereby not taking food acreage out of production. Furthermore camelina has a relatively short growing season of 80 to 100 days, requires no special equipment to harvest, and the silage remaining after processing can be fed to livestock and poultry, with the added side benefit of increasing their omega-3 production. Camelina is increasingly emerging as a prime biofuel source and thus attracts investment worldwide, as global demand for aviation fuel for passenger flights is now more than 40 billion gallons annually. In the earlier of this year, USDA announced two Biomass Crop Assistance Program (BCAP) project areas devoted to developing camelina as biofuel in several states, including Montana. USDA's Risk Management Agency (RMA) has also recently announced a new pilot program of insurance for camelina beginning with the 2012 crop year.

Future Feed-in-Tariff Trends for India – for Wind, Solar and Other Renewable Power Sources

It is an open secret that renewable power requires incentives - these usually are in the form of capital subsidies, tax incentives and most importantly, via feed in tariffs. It is a million dollar (make that Billion Dollar) question what the future of feed in tariffs will be for the mainstream renewable power sources. I picked up some resources on these. Wouldn't say they provide a peek into the future, but at least one of these try telling us how the government arrives at these numbers, so that will provide us with some clues.

How Biogas-based Power Generation is Picking up Pace in India

===========================================

Are you looking to get energy security for your company through reduction in the use of diesel, furnace oil, LPG and costly grid power? EAI can do a feasibility study for the use of solar PV & thermal, biomass for heat and power, waste heat recovery and energy efficiency to dramatically cut down fossil fuel use and reduce your energy bills. See EAI's SURE-FIRE offering for more.

 ===========================================

 Most of us have come across the gobar gas – literally meaning gas from the cow. It is the same as what is called biogas. This is the gas that is released when bacteria feast on organic matter – typically human and animal feces – and release a gas that is about 50% methane. While biogas had predominantly been used earlier for heating purposes, its use for power production is also beginning to show a marked rise across the world, and in India too. How is power produced from biogas? The process is actually quite simple. Step 1 is generation of biogas. This is done typically using what are anaerobic called digesters. Animal (or human) waste is fed into the digester, where the microorganisms (called methanogenic bacteria) act upon it. Depending on the type of digester, it could take anywhere between 10 days to 15 days for the waste to have been "digested" by the bacteria and the release of biogas. The biogas thus produced can be used in IC engines specially devised for the use of biogas. These engines are similar in working principles to diesel engines and natural gas engines. These engines produce electricity from biogas. A bit of observation will lead us to easily understand why this concept will be of enormous interest to specific industry segments. Two segments stand out - industries that employ large numbers of animals and sewage treatment plants that treat human waste. Both these segments have started benefitting from this concept; as a result, we have a few STPs (sewage treatment plants) already generating power from the sludge generated (one of the STPs at Chennai, at a town called Nesapakkam, generates about 500 kW of power from the waste, and uses the power generated for all its electricity purposes). Some numbers will help understand the potential available for power generation from biogas. The cow population of India (about 225 million) alone generates about 800 million tons of wet dung which translates to about 150 million T of dry weight. 1 Kg of dry cow dung can generate about 1.2 kWh of electricity (it can generate the equivalent of about 4 kWh thermal). Thus, if all cow dung were converted to electricity, that would be 1.2*150*1000 million kWh = 180 TWh. India generated a total of 855 TWh in 2011-12. This implies that cow dung, if entirely converted to power, would have produced about 20% of total India's power! If the waste of other cattle and human waste were also taken into account, this could be about 30%. That is an awesome number. Of course, these data hide the actual difficulty in converting even a small portion of animal or human waste into electricity, owing to the infrastructural and social problems associated with these. All the same, waste -> biogas -> power is quite practical to a whole host of industries for whom such waste is available on premises. More information about waste to energy in general in the Indian context, is available from EAI's waste to energy resource section. Some of the following YouTube videos provide a more visual account of how to generate biogas from organic waste: Biogas from food waste - ARTI - http://www.youtube.com/watch?v=BGSl72xZHNk&feature=related Bio-gas from kitchen waste and bio mass - http://www.youtube.com/watch?v=uppVZGS7bYI&feature=related Biogas from Vegetarian Food Waste - http://www.youtube.com/watch?v=NZFrPZZIFTs&feature=related Biogas from Human Waste - http://www.youtube.com/watch?v=_m1nr2v5S8o And while on sewage, human waste and toilets, etc, a couple of interesting articles on things are emerging New toilet technology after 150 years of waste The seat of power - Better sewage treatment is the latest thing in clean energy Also check out: EAI Consulting for Bio-energy & Biofuels, Bioplastics & Other Biomass-based Value Added Products

How Punjab Will Benefit from All Its Agricultural Residue- A Case Study

Agricultural residues never go to waste. Not when they can be used for generating energy. In this context, the government of Punjab, India, plans to produce about 1,000 MW of green energy from livestock residues by 2015. When you think about it, this has huge economical and environmental benefits. In a region where large quantities of cattle manure become a major pollutant, this could be seen as an opportunity that could open a lot of doors. Aside livestock residues, the state also generates nearly 21 million tons of rice stalks and similar biomass plant wastes annually, which can all go into the production of green power. The state government is thus planning to make renewable resources as the source of their power to contribute 10% of its total energy production in the next five years. It is worthy to mention that Punjab already runs a biomethanation facility with a capacity of 1 MW, in a location close to Ludhiana. The facility uses methanogens (microbes that produce methane as a metabolic by-product) for the manufacture of methane gas. It currently uses 235 tons of cattle wastes to generate 18,000 kWh of electricity in addition to producing 45 tons of organic fertilizer every day. Also, the Punjab Energy Development Agency has developed 318 MW of green power projects, which includes the Ludhiana plant, till date. These projects comprise 37 MW of small hydro facilities, 28 MW of biomass power facilities, 250 MW of biomass co-generation facilities and 2 MW of solar projects. The agency also develops 132 MW of green power projects currently, which include 11 MW of hydropower, 100 MW of biomass co-generation and 20 MW of traditional biomass. If everything goes right and operational, the state will generate 700 MW of green power by 2012. That’s big! It is worthwhile to note that the planters are also getting an income of nearly RS. 4,000 per acre every year in the process of marketing agro wastes to biomass facilities.

Industry Perspectives and Strategies for Effective Biomass Feedstock Procurement

===========================================

Are you looking to get energy security for your company through reduction in the use of diesel, furnace oil, LPG and costly grid power? EAI can do a feasibility study for the use of solar PV & thermal, biomass for heat and power, waste heat recovery and energy efficiency to dramatically cut down fossil fuel use and reduce your energy bills. See EAI's SURE-FIRE offering for more.

 ===========================================

One of the most critical bottlenecks for biomass power plants is the supply chain bottlenecks that could result in non-availability of feedstock. A related problem is the volatility, or more precisely increase, in the feedstock price. Both these could render the project unviable. Highlighted in this article are some of the industrial perspectives in overcoming barriers for procuring a balanced feedstock supply. EAI’s research with industry experts suggest that there is no established biomass value chain that exists in India for the procurement and transportation of the biomass feedstock. Typically, the facility staffs  from a biomass gasification plant acquires biomass from several to dozens of small-scale biomass suppliers on a relatively informal, non contractual basis; although some have considered the use of aggregators, there is no data or proof available from the Indian biomass gasification companies that have engaged such a service as yet. The biomass procurement model that is typically followed in India is discussed below: Route #1 – Biomass Producer -->Transport Contractor --> Biomass Collection Centres (BCC’s) --> Power Producers The biomass producer i.e. the farmers/mill owners hands over the feedstock to a transport contractor who in turn delivers the feedstock to the biomass consumers or BCC’s. The BCC’s (managed by the biomass consumer) pay the farmers and the power producers collect the feedstock from these collection centres as and when required. At some instances, the farmers deliver the feedstock in the power producer’s facility and get directly paid for it. Route #2 - Biomass Producers --> Waste Processing Mills -->Biomass Power Producers For feedstock where further processing is required, the farmers/mill owners deposit the feedstock in waste processing mills. From the waste processing mills through a transport contractor the feedstock is deposited in the BCC’s or directly in the power producer’s facility. In some cases, especially in briquetting, the processing is done in the collection centres itself where a mobile briquetter is taken and the briquettes that are processed are directly delivered to the facility or collected by the power producers. Key Strategies to be Followed for Effective Biomass Feedstock Procurement EAI’s interactions with the industry reveal that the following strategies have to be adopted   in order to bring both the availability and price of biomass under control:
  • Security should be addressed by obtaining a written formal supply agreement with a reputable, local supplier. A five-year signed supply agreement with pricing and minimum volumes can go a long way in helping to secure necessary financing. A bioenergy project that is totally reliant on only one source of feedstock will be at risk, so two supply contracts are even better. This will also allow one to negotiate a better feedstock price, as the supplier will benefit from a long-term relationship and a guaranteed market. An interested lender needs to know that both the feedstock supplier and bioenergy processor are committed to the project.
  • It can be beneficial to hire an independent professional to verify one’s biomass supply projections and double-check that the feedstock supply is sustainable over the long term
  • Backward integration and own captive biomass source (one company, Orient Green Power, is even trying out a novel technique of going for energy plantations on their own wind farms)
  • According to the Washington based biomass supply company ‘Powerstock’, for a well-managed supply, an inclusive definition of biomass is needed. The company is also taking efforts to educate the public on the value of well-managed, productive forests.
  • The bottom line of feedstock security is composed of several aspects: grower relations, harvesting, marketing, equipment utilization, proprietary techniques and agricultural economics. Hence it's important to manage the entire process from seed to market.
  • The supply sector needs to make the transition from a residues-based approach to an integrated, dedicated feedstock supply system using energy crops, plus residues.

Potential for Biomass Power in India

Biomass based power generation is a choice of reality under the geographical regions where a sustainability exists in the flow of biologically raw materials for the production of power and India is one of the most notable universal giants for the production of biomass based power which can be best understood from the estimates of its biomass availability and the power produced from it. India has biomass production of 546 million tonnes per year from the agricultural sources alone to generate electricity at a capacity of 17,982 MW and its overall production of power from renewable sources stands at 34961 MWe in 2010.A calculated annual growth rate for the next decade realistically and optimistically is above 42,000 MWe and 48640 MWe respectively. The development of biomass based power is further enhanced by the Government regulatory policies by declaring duty exemptions’, tax breaks and financial incentives etc. The cost of producing electricity from biomass is affordable at Rs: 2.25-3.25 / kWh. In spite of all these attempts biomass based power generation is at its infant stage because of hindering factors such as feedstock availability, transportation, price volatility etc. India to emerge as a role model must utilize its renewable energy sources to a large extent, develop dedicated energy crops, establish end user market for co-products such as charcoal, biochar, activated carbon, and implement energy efficient technology for economically feasible power generation on a massive scale.

PRESPL Secures ₹4.1 Million Investment from Mitsui for Biomass Growth


This post is a part of Climate G2I Intelligence series from Energy Alternatives India (EAI), India's leading climate-tech consulting firm.

G2I stands for Gateway 2 India, and provides comprehensive market intelligence and go-to market assistance for International firms entering the Indian climate-tech market. More about Climate G2I from here


Mitsui, a leading Japanese conglomerate, has recently invested ₹4.1 million in Punjab Renewable Energy Systems Pvt. Ltd. (PRESPL), a company focused on collecting agricultural residues and converting them into biomass briquettes and pellets. This investment underscores the growing potential of the Indian biomass sector, which is expected to witness significant growth in the coming years.

The Indian biomass market is estimated to be valued at around ₹50,000 crore and is projected to reach ₹1,00,000 crore by 2025, driven by factors such as the Increasing demand for renewable energy, Growing awareness of environmental concerns, and  Supportive government policies.

The Indian biomass sector is also witnessing a surge in international collaborations, with several prominent companies entering the market through partnerships and alliances. For instance,  Aramco, a prominent oil and gas company, joins forces with ReNew Power, India's largest renewable energy company, to explore opportunities in developing and deploying low-carbon technologies, including biomass-based power solutions. This collaboration signifies the growing interest of leading energy giants in exploring cleaner alternatives. 

Additionally, Danish Biogas's collaboration with the Maharashtra Energy Development Agency (MEDA) brings together expertise in advanced biogas technologies with experience in promoting renewable energy and rural development in Maharashtra. This partnership contributes to a more sustainable waste management system through biogas generation..

These strategic partnerships are just a glimpse into the exciting developments propelling the Indian biomass sector forward. The government is also playing a crucial role in accelerating its growth through supportive initiatives like subsidies for setting up biomass power plants and briquette/pellet production units, promoting dedicated energy crops and efficient residue collection systems, and providing tax benefits for biomass projects. Investments in research and development are also being made to improve conversion technologies, optimize feedstock utilization, and develop cost-effective biomass solutions.

Navigating this complex ecosystem requires a comprehensive understanding of the key players involved. The Indian biomass value chain comprises various stakeholders, including biomass producers like farmers and forestry companies, collectors and aggregators responsible for managing feedstock collection and storage, processing and conversion companies that transform biomass into usable forms, original equipment manufacturers (OEMs) who create machinery for the sector, suppliers providing essential goods and services, power plants and industries utilizing biomass-based fuels, and government agencies responsible for regulation and promotion.

Beyond the core value chain, the adjacent value chain plays a crucial role in supporting the sector's growth. This includes financial institutions offering loans and investments for biomass projects, research institutions and universities engaged in R&D advancements, and non-governmental organizations (NGOs) promoting sustainable practices and advocating for policy changes.

Indigenization remains moderate to low currently, with reliance on imported technologies and equipment. However, government initiatives and rising demand are expected to gradually increase domestic capabilities in the coming years.

Primary Routes for Power from Biomass

The three primary routes for biomass to power are: Combustion, Gasification and Anaerobic Digestion. Combustion is easy to understand – instead of using coal or other fossil fuel, use biomass to produce steam that runs a turbine. Combustion of biomass for power could either be in the form of co-firing (when it is burned along with coal) or pure play biomass based combustion. In the case of gasification, the biomass is first gasified and this gas turn produces power in a gas engine. Anaerobic digestion is usually applied to biomass that typically have a high amount of water in them (anaerobic digestion is most used for treating organic waste such as kitchen waste and sewage waste into energy). Under this route, microorganisms act upon the organic matter present in the biomass under anaerobic (absence of air) and convert it into biogas. An emerging route for biomass based power is pyrolysis. In this, the biomass is rapidly heated to 450 - 600 °C in absence of air, and results in a bio-oil called the pyrolysis oil, which can in turn be used for firing the boilers. Typically, 50 - 75 % (by weight) of the feedstock is converted into pyrolysis oil. Pyrolysis as a method for power production is not well established currently in India or elsewhere in the world. Typically pyrolysis plants work well beyond 2 MW scale, while gasification plants work well until 2 MW scale, at the current technological progress. Thus, it can be said that pyrolysis takes off where gasification ends. Also check out: EAI Consulting for Bio-energy & Biofuels, Bioplastics & Other Biomass-based Value Added Products

Prominent biomass feedstock for gasification

Biomass for power generation by combustion or gasification is normally variable in its chemical composition of electron rich reactants, ash content, moisture, sulphur and nitrogen content etc. As a result, selection of the most convenient feedstock is an issue of debate. The degree and diversity of contaminants strongly influence the production and purification of synthesis gas in gasification while they tend to have a minimum effect in the combustion process. Independant of these disturbances virtually any raw material applied in power generation process should be a matter with potentials. In India, a vast array of feed stocks are utilized for power generation but the most wide ones are farm and mill wastes, woody trees, energy plantations and other green manure crops. Preference is made on the basis of availability, cost, bulkiness of the material, pre-processing, storage etc. Biomass used in India yields varying level of energy but it is also the gas engine and generators whose efficiency equivalently determine power generation.

REC Price Band Revised

The Central Electricity Regulatory Commission(CERC) has announced the floor and forbearance prices to be used for solar/non-solar projects from the FY 2012-13 upto 2016-17. The prices set are shown in the table below

Non Solar (Rs.) Solar (Rs.)
Prices (2012-2017) Current % Reduction Prices (2012-2017) Current % Reduction
Forbearance Price 3300 3900 15.38 13400 17000 21.18
Floor Price 1500 1500 0.00 9300 12000 22.50
Background Earlier, the CERC had proposed a few changes (refer table below) to be made to the REC prices and invited comments/suggestions on the same.
Non Solar (Rs.) Solar (Rs.)
Proposed Current % Reduction Proposed Current % Reduction
Forbearance Price 3480 3900 10.77 13690 17000 19.47
Floor Price 1400 1500 6.67 9880 12000 17.67
  The final prices to be enforced from April 2012 were arrived at after considering the comments/views of stakeholders and participants at the public hearing on the proposed floor and forbearance prices. As can be seen, the final prices decided upon are considerably lower than the earlier proposed prices. Analysis Financial feasibility studies of power plants under the REC mechanism almost always consider the floor price for calculating returns. With this in mind, the evaluation of REC for the primary renewable energy generation systems looks quite healthy.
  • Non-solar – the floor price remains unchanged. Thus biomass/wind generators are expected to get the same minium revenue as they have been getting earlier.
  • Solar – the floor price has seen a cut of about 23% from current levels. Although this might seem drastic, it is not likely to have a significant impact on solar power projects (refer section below).
  APPC – Non preferential tariff and REC CERC stipulates that for a project to be eligible under the REC mechanism, the power producer has to sign a PPA with the state utilities at a price equal to the APPC price. The APPC price for a state for a particular time period is determined by the State Electricity Regulatory Commissions(SERC). Looking at the current APPC prices in various states, a combination of REC and a PPA signed at APPC rates seems comparable with the preferential PPAs signed with the state utilities. For example,  let us consider a solar PV plant to be setup in Tamil Nadu where the APPC price for 2011-12 is Rs. 3.38/kWh. Under REC regulations, if a RE developer were to get the floor price for the solar REC, the income for the solar PV plant would be Rs. 12.68 /kWh (Rs. 3.38 + Rs.9.3). Another case is Rajasthan, which has a very high potential for solar PV – where the income would be Rs. 11.9 /kWh. In comparison, under the phase 1 (batch 1) of JNNSM, the average price settled on through the reverse bidding process was  about Rs. 12.5 per kWh. As can be seen, these prices are comparable to tariff set through reverse bidding under batch 1 of the JNNSM scheme. Prices can only go higher APPC prices are set based on the cost of power generation from fossil fuel based power plants. It is highly likely that this price would increase in the future due to the increase in fossil fuel prices and scarcity of supply. This ensures that the APPC prices would continue to increase for the foreseeable future, thus ensuring higher year on year returns under the REC mechanism provided the PPA signed with the state utilities has provisions for purchase at floating APPC prices rather than fixed price. The table below gives a comparison between preferential tariff (reverse bidding under JNNSM) and REC mechanism for a plant in Tamil Nadu. The following assumptions were made for the sake of calculations
  • Average bid price under phase 1 batch 2 of JNNSM could be around Rs. 12.5 /kWh(on the higher side)
  • APPC prices could rise by 15% annually (base price used is that of Tamil Nadu) - reasons for this were mentioned earlier.
  • REC price after 2016-17 period (i.e. from FY 2017-18 onwards) is reduced by 25%
 
Year 2012 2013 2014 2015 2016 2017 2018 2019 2020 2021
JNNSM Tariff (average) (Rs. per kWh) 12.5 12.5 12.5 12.5 12.5 12.5 12.5 12.5 12.5 12.5
APPC (Rs. per kWh) 3.38 3.89 4.38 5.04 5.38 6.19 6.38 7.34 7.38 8.49
REC (Rs. per kWh) 9.30 9.30 9.30 9.30 9.30 6.98 6.98 6.98 6.98 6.98
Total (Rs. per kWh) 12.68 13.19 13.68 14.34 14.68 13.16 13.36 14.31 14.36 15.46
REC mechanism's Incremental revenue over PPA(Rs. per kWh) 0.18 0.69 1.18 1.84 2.18 0.66 0.86 1.81 1.86 2.96

Table: REC vs preferential PPA for 10 years post 2012

As can be seen from the above table, the REC mechanism is quite comparable, if not better when compared to the assured tariff provided by NVVN over 10 years of operation of the solar powerplant. Overall, the REC mechanism can clearly drive the solar market, provided the Renewable Purchase Obligation (RPO) is strictly enforced by the various SERCs. The CERC release can be found here.   Also check out: EAI Consulting for Bio-energy & Biofuels, Bioplastics & Other Biomass-based Value Added Products

REC Trading – November 2011

The REC trading for the month of November concluded yesterday. Figures reveal that the trading has increased significantly both in volume of RECs traded as well as the price. In total 105,527 RECs were sold. Keeping with the trend of previous months, IEX had a higher share of the market with 96,154 (90%) RECs traded while PXIL saw trading of 9,373 (10%) certificates. The large volumes of trading indicate that the obligated entities are trying to fulfil their RPO as soon as possible as REC prices are showing an upward trend. The price of REC varied between the two exchanges - IEX and PXIL. Non-solar RECs closed with a price of Rs. 2,900 at IEX while the RECs sold at Rs. 2,800 at the PXIL. At the IEX, the prices have seen a 7% rise over those paid last month where the trading price was Rs. 2,700 per REC.

PXIL 51,199 9,373 2,800 0 - -
Total 308,777 105,527 - 43 - -
Interestingly, there are 43 buy bids for solar REC; this suggests that the solar REC market is gathering steam. This growing interest suggests that solar projects being planned based on REC may soon be bankable and we could see a trend in developers going for the REC mechanism during the interm period between now and the second phase of the National Solar Mission. Solar developers have another reason to rejoice as well as maintain a shrewd view on the Solar REC market. This month saw the accreditation of the first Solar project under the REC mechanims - an 8.5 MW solar project located at Jalgaon, Maharasthra developed by Jain Irrigation Systems. This project's viability has to be closely followed over the coming trading sessions as the REC certificates generated from the project slowly start coming up for sale. In total there are about 244 projects registered under REC with an aggregated capacity of 1551.92 MW (this excludes the lone solar project that recently got accredited). Conclusion The REC market continues to impress with higher sale prices and volumes. The REC prices are expected to rise over the coming months given the fact that there only 4 months left for RPO compliance. However, the price as such is expected to rise only gradually and not at the high rates seen over the year. The registration of a solar project under the REC mechanism might open the flood gates for more solar projects depending on the performance of the solar RECS. This could lead to a pradigm shift in the solar project development in India, which up until now has looked up to the state/central solar policies as the only source for project viability thereby reducing the cost of solar power in India and accelerating the road to grid parity.   Also check out: EAI Consulting for Bio-energy & Biofuels, Bioplastics & Other Biomass-based Value Added Products

REC Trading – September 2011

The REC trading for the month of September concluded recently. Trading figures reveal that the trading has increased significantly both in volume of RECs traded as well as the price. In total 46,362 RECs were sold. Keeping with the trend of previous months, IEX had a higher share of the market with 41,385 (89%) RECs traded while PXIL saw trading of 4,977 (11%) certificates. The large volumes of trading indicate that the obligated entities are trying to fulfil their RPO as soon as possible as REC prices are showing an upward trend. The most encouraging part of the trading was the price paid for each certificate. The price of REC grew to Rs. 2300 from Rs. 1800 last month.

Interestingly, there are 7 buy bids for solar REC; up from the lone buy bid last month, although this is promising, it highlights a serious issue. As with the previous months, there are no solar RECs available as no projects are registered under REC. This is a worrying trend and is going to put immense strain on the obligated entities to fulfil their solar RPO. The reasons for lack of solar projects registered under REC could include

  • Higher payback period for solar projects
  • REC prices guaranteed only up to 2016-17
  • A combination of the above two greatly reduces the bankability of solar projects
Conclusion The increase in REC trade volumes and price is very encouraging. It shows that the mechanism is a viable revenue route for developers who have not signed any preferential PPA. The demand for REC certificates is bound to keep increasing as more and more obligated entities try to fulfil their RPO in the short time span available. This is scheduled to push the REC price even further which in turn could lead to REC prices hitting their forebearance highs in the coming months. Finally more effort needs to be put in to ensure that there is sufficient supply of solar RECs in the market.

The effect of each of the raw material for a module(metallisation paste, ribbon, flux, encapsulant,etc) on the final quality of the PV module was also discussed. That concluded the 3rd edition of the Renewtech India conference. The 4th Renewtech India conference is scheduled for 16-18 February 2012 at the same venue – Bombay Exhibition Centre, Goregoan, Mumbai.

Rice husk used for power in one of India’s poorest states- A case Study

Whoever thought rice husk can generate power needs a medal! Considering how much rice husks go to waste in a country where rice is the staple food, it is comforting to know fossil fuels are not our only resort for power production. Thanks to Manoj Shinha, a renewable energy entrepreneur pioneered using discarded rice husks as biomass to provide energy to Bihar, one of India’s poorest states. Mr. Shinha along with his colleagues Gaynesh Pandey, Ratnesh Yadav and Charles W. Ransler developed Husk Power Systems to address the situation of poverty in their home state of Bihar. Many villages in India live off the grid in the darkness, this new advancement means that they need not depend on grid for electricity, rather generate their own clean, affordable electricity.The company generates and sells electricity for a price that is less than half of what the villagers pay for kerosene. This was possible because the whole concept is focused on research and development investment to simplify energy production and transmission, such as using bamboo instead of cement posts to install power lines.And, since communities no longer use kerosene, wood or dung for electricity, this way of electricity generation lowers the environmental and health hazards. In addition, rice husk ash, a byproduct of the gasification process, can be used for concrete production thus reducing the amount of high-carbon Portland restless leg syndrome cement.On average, a single power plant serves 400 houses, replacing 42,000 liters of kerosene and 18,000 liters of diesel yearly. As of August 2010, H.P.S. has sequestered 50,000 tons of carbon dioxide. Currently, they have installed over 60 mini-power plants that are 100 percent biomass-based which supply power to over 25,000 households in more than 250 villages.With the market opportunity in mind, they aim to expand their business to bring clean electricity to Indian villages by installing 2,000 new plants by 2014 beyond Bihar.

Tamil Nadu’s Biomass Power Plans – Energy Plantations is the Answer?

Biomass is one of the renewable energy domains in which Tamil Nadu could have significant potential for progress in future. Estimates suggest only about 10% of the potential has so far been utilized. Of course, the lack of a robust supply chain that make create supply and price security is a problem as much in Tamil Nadu as it is in the rest of the country. Some inputs and updates for biomass power in Tamil Nadu are provided below.

  • Potential for Biomass based power in Tamil Nadu is 1589.9 MW (1160 MW based on agricultural waste and 429.9 MW from forest and wasteland cultivation).
  • 22 biomass power plants with total installed capacity of 169 MW are in operation.
  • Ten biomass power plants with totaling to 120 MW, with over 80% plant load factor, have faced temporary shut downs owing to unviable tariff rates and increasing feedstock cost.
  • Biomass power producers association has approached Tamil Nadu Electricity Regulatory Commission (TNERC) with a request to revise the tariff and offer higher annual tariff escalation. The viable rate for operating biomass power plants in years to come would run beyond Rs 6.50/kWh, but the current tariff of Rs 4.5/kWh is in no way adequate to sustain the projects in the long run.
  • Tamil Nadu Energy Development Agency (TEDA), along with Tamil Nadu Biomass Power Producers Association, has been actively involved in promoting large scale energy plantations in marginal / waste land in the state with high potential crops.
  • The Tamil Nadu Biomass Power Producers Association suggests that energy plantation would not only serve to provide cheap and continuous feedstock supply for power plants, but it would also improve the quality of life of the rural population. Estimates suggest that a 10 mw biomass power plant can ensure livelihood of over 2,000 marginalised families. They can be employed in collection, transportation, cutting, chipping of biomass and cultivation of wasteland with energy plants like Juliflora, Bheema Bamboo etc.
So, it looks like Tamil Nadu is betting significantly on energy plantations for a viable biomass power sector. Let’s hope they have got it right. Also check out: EAI Consulting for Bio-energy & Biofuels, Bioplastics & Other Biomass-based Value Added Products

The man propelling the bio-energy movement in India – PRESPL

Welcoming Lt Col Monish Ahuja to CLIMAFIX SUMMIT 2022 - the 1st summit for Indian climate tech startups. I'm sure you have heard the saying, "Water, water everywhere, not a drop to drink" That applies quite well to the Indian agricultural residues as well. Hundreds of millions of tons of agro waste around the country, but very little available for the industries to use. And worse, a good portion gets burnt on the fields because the farmers do not know what to do with them. So where's the challenge? What is broken in this system? To a significant extent, logistics, or rather the lack of it. Securing and transporting millions of tons of agricultural waste from hundreds of thousands of farmers and transporting it reliably to end users is not rocket science. But it is systems science. Discipline science. Or patience science, if that term is more endearing to you. In EAI's decade long work in the bio-energy sector during which we consulted for dozens of clients including the likes of GSK (#Horlicks division, now part of Unilever), we have seen how unorganized the agro-waste supply has been, except for bagasse coming straight from large sugar mills and to a lesser extent saw dust from plywood factories. It is a complex challenge of logistics, societal & local traditions, and of course the omnipresent politics. The sector needed someone who could wade through all these, build an efficient system and evolve an organized biomass supply chain. Enter Lt Col Monish Ahuja. Army discipline, Systems thinking. Business acumen. These characteristics have helped him build Punjab Renewable Energy Systems Private Limited (PRESPL) into a force to reckon with countrywide in industrial biomass supply. PRESPL is today is one of the few organized players that has the ability to provide industrial decarbonization on scale through biomass, supplying thousands of tons of agro-waste based biomass every day to industries. I remember sitting with him in his office in Navi Mumbai a few years back when he patiently took me through the process by which he was building an effective front-end logistics system while also putting together a scalable digital back-end system. While coming out from the meeting, I thought - finally, here's someone who appears to be just what the doctor ordered for India's bio-energy sector. Since then, his company has - not surprisingly - grown and grown. Hats off to Monish, and we are proud to have him as one of the experts who will share his insights at the CLIMAFIX SUMMIT 2022, India's first climate startup summit, Nov 25 & 26, Chennai, organized by the Climate Startup Intelligence division CLIMAFIX of EAI (Energy Alternatives India) & Energy Consortium - IIT Madras Welcome Monish, and here's hoping you inspire more of your breed - and soon.

VC / PE Perspectives and Opinions on Biomass Power

Indian VCs have not really done a good amount of investing in cleantech. Cleantech perhaps  is not really a VC game as it is more of an engineering related discplie that does not offer the types of scalabilitiees that VCs desire or the exit periods. VCs also do not understand cleantech well enough to take calls. Many cleantech deals, especially in the power segment, are PPA based, with limited upsides, not typical VC games. Many cleantech and renewable energy startups require capital that is much higher than what VCs can typically offer to invest. Predictions for Cleantech VC in 2011 - Kachan & Co.'s Dallas Kachan looks at what 2011 will have in store for cleantech (http://alwayson.goingon.com/node/66783 ) Sustained worldwide venture capital investment will continue to cede importance to corporate and non-institutional capital. A return to early stage venture investments - predict a return to early stage venture capital investing in cleantech in 2011. Energy efficiency emerges as the clear rock star of cleantech. Biofuel investment could reach former highs. Recycling and mining will attract more investment. Natural gas emerges to threaten solar and wind for utility renewable power generation. China becomes the most important market for cleantech: if you're not selling in China, you won't matter. There is a significant amount of interest among PEs for investments in both traditional and renewable energy. PEs – not surprisingly – are not very keen on risky technology bets in renewable energy, but are OK with business model risks. Some of the PEs (such as IFC, ADB etc) are willing to take fairly long-term views (with over 10 year horizon). Investment sweet spot ( in terms of the quantum) varies from fund to fund, but obviously for most of the blue-chip, it is upwards of $50 million. PEs are well aware of the regulatory and societal bottlenecks that could arise in large-scale energy sector investing (especially for coal-based and large-hydro based sectors). Many PEs are clear that they wish to invest in businesses that can stand on their own revenues (even if takes a while) and are not keen on business plans that rely on getting bought out. Most every PE acknowledged that while they might not like coal, it is here to stay as the largest contributor to power for the foreseeable future. PE arms of organizations such as IFC and ADB, while not shutting out the option of investing in coal-based or natural gas based power plants, have a mandate to decrease their exposures to these “non-green” sectors. What a PE can bring to the table - Many private equity funds have been able to provide not just the financial support required but also strategic support and value-add for the firm’s growth. Disconnect in Valuation expectations - one of the issues faced by PE players while investing in cleantech companies is the disconnect in valuation expectations between the entrepreneur and investor with the buoyant public markets resulting in an increasing buoyancy in expectations! PEs feel that entrepreneurs should take a longer term view while setting their valuation expectations. Currently, 80% of infrastructure projects, and 46% of power projects, are funded by the banking system. So, PEs constitute only a small share of the infrastructure projects. While private equity folks could like IRRs of about 25%, power and infrastructure IRRs is only about 12%. Some private equity companies might wish to play a consolidator’s role as well where they consolidate a diverse portfolio of (say) energy companies such that they win even if 7/10 companies do well enough. Investors such as IFC have specialists/experts in every project to take care of social and environmental aspects. Private equity funds are interested in the macro factors (demand supply gap in electricity et al) as well strategic micro factors. One of the factors that seem to interest PEs is the method for companies to go diversified on green power that is having assets in wind, small hydro, biomass etc together, instead of betting just on one thing alone.

Why Biomass for Power Generation?

Biomass has been used as a source of energy right since mankind started its existence; In fact, one of the predominant energy sources today is biomass. Biomass as a source for power production is not entirely new either. Biomass has been used, in the place of coal, for steam generation at power plants, though in a limited way. Indeed, currently, the predominant method used for producing power using biomass still is the combustion route, At the same time, other processes, such as biomass gasification, which can work at much smaller scales and use the biomass more efficiently are emerging. The newer processes especially biomass gasification based power production, is relevant today especially in the Indian context mainly because of its potential to provide distributed power at rural level, especially for small remote villages that have good access to biomass but no access to grid power, and which require only small scale power production. Biomass based power is also relevant in the context of climate change and global warming as biomass based power production is net carbon neutral. The contribution of bioenergy to the total primary energy consumption in India is over 27% (Source: FAO). This is indeed the case for many other countries, because biomass is used in a significant way in rural areas in many countries. However, the contribution of biomass to power production is much smaller than this percentage – currently, biomass comprises only about 2650 MW of installed capacity, out of a total of 172000 MW of total electricity installed capacity in the country. Besides, biomass power has the following benefits- distributed generation, baseload power, ability to have small, kW scale power production, suited for rural areas and ideal for rural economic upliftment. I believe these are enough to justify why biomass is best suited for power production. Check out: EAI Consulting for Bio-energy & Biofuels, Bioplastics & Other Biomass-based Value Added Products

A 900 MW Power Plant Running on Biomass? It Could be a Reality in Five Years!

I thought I was never going to see the day when a large power plant would run entirely on biomass. You can understand my pessimism when you are told that a MW of powerplant will require about 8000 T of biomass every year. A 300 MW power plant will hence require an awful 2.5 million T of biomass every year. That's a heck of a lot of, well, anything. Well, there are some courageous folks around the world. Drax in the UK, for one. They are building 3x300 MW furnaces on biomass, and are arranging for a 8 million T biomass supply from around the world. (By comparison, India's total biomass based power production - outside of bagasse power - is only about 1500 MW. So the Drax project alone would be about 60% of total Indian biomass installed capacity!) While I am certainly overawed, good news, I must say. If they can operate it sustainably for a few years, biomass power would have definitely reached a milestone. Will be really keen to know how they plan to manage the supply chain. This is what the news report has to say "The vast majority of the biomass will come from North America, but there will also be locally sourced supplies of willow and elephant grass to power the furnaces. "

A Case Study of Clenergen and Yuken’s Gasification Biomass Project

Yuken India Limited, set up in 1976 under a technical and financial collaboration with Yuken Kogyo Company Limited, Japan, is a manufacturer of oil hydraulic equipment. Yuken has achieved one of the fastest growth rates in the Indian oil hydraulics industry, in the last 29 years. Clenergen India Private Limited, a wholly owned subsidiary of Clenergen Corporation, plans to enter into a minimum 15 years Power Purchase Agreement (PPA) with Yuken to supply up to 2.5MW/h, with the rest of the electricity generated being completely sold out to the National Grid System. The biomass power plants with a capacity of 4 MW/h will be installed and begin operation within 10 months upon signing of the PPA. Clenergen India plans to lease up to 800 acres of non arable land near the manufacturing site in order to grow a high yielding species of bamboo as a source of biomass for the gasification power plant. The bamboo produced is asexual, non-invasive, non-flowering plant with a lifespan of up to 50 years and above all, is a product of tissue culture. This is advancement in the sector of renewable energy, in that the cost savings created from the cultivation of biomass feedstock will allow the supply of electricity at a price lower than the current market prices and will also help to extend the industries’ vertical market penetration into these market sectors. This is certainly moving forward. With ever increasing fossil fuel prices, this is the ideal way to deal with the growing needs and the economy.   Also check out: EAI Consulting for Bio-energy & Biofuels, Bioplastics & Other Biomass-based Value Added Products

Agricultural biomass availability in India for power generation

India is primarily an agricultural nation with an extensive cultivation of different types of crops including cereal, pulses, oilseeds, fibre crops, spices and plantation crops. With the cultivation of these crops, availability of residual biomass after economic harvest makes power generation in a sustainable way. These raw materials are normally available in variable quantities depending on the acreage of cultivation, mass of residue part available. The total biomass is 511,041 kT/Yr for power generation. Among them, rice, wheat and cotton constitute a major portion with 160,000,111,000 and 21,000 kT/Yr to generate power of 5000, 3300 and 3500 MW respectively. The total power generation capacity is 17,400 MW. Besides these crops, maize, jowar, bajra, coconut, groundnut, banana, cassava and mustard are also potent generators of biomass for power to an appreciable extent. It is evident from the information stated above that the agricultural resources serve as excellent candidates for the power generation either by combustion or gasification. However it is important to note that these materials are variables by biochemical composition and moisture. So, standardization is mandatory by defining limits to make them appropriate for thermal decomposition and as consistently yielding materials of electric power. Further plans are required to efficiently collect and store for processing without time delay.

Benefits of Biomass Based Power

While we are striving hard to switch to more sustainable modes of living, there arise lots of issues questioning the efficiency of our choice of green.  Despite all the issues they might have, they have more benefits than their petroleum counterpart. After all, petroleum is not going be here forever. So, this post will focus on the benefits of biomass based power, and why is it more suited as a sustainable alternative. Let us look at the distributed generation, because biomass is available in almost all places, and especially in rural areas, and more important, as gasification based power production can be done on small scales (as low as 20 kW), this process can be used for distributed generation of power as against the centralized power production method followed today. Also, biomass based power is well suited to remote villages with no access to grid but access to significant amounts of biomass Secondly, biomass gasification based power production can be done at small scales – as small as 20 kW – unlike other sources of power (say, nuclear) that require much larger scales. This will ideally suit small villages that have only a few households. Also, this whole process could be done in rural areas, where this could open a gateway of opportunities for rural population. Given that a 1 MW biomass based power generation could require biomass growth in over 150 hectares, the opportunities for rural employment are indeed significant. Thirdly, biomass power results in no new net GHG emissions as it is part of the carbon cycle. Unlike coal and others forms of fossil fuel which have been buried millions of years ago and burning them adds to carbon in the atmosphere, responsible biomass energy generation results in no new carbon emissions or pollution. Finally, the efficiency of the biomass power generation process to make use of mostly animal and crop wastes for energy is remarkable. Also, there is a large variety of feedstock which could be used for the process. Aside from these, they also significantly reduce methane in the atmosphere, which being able to be produced economically. I suppose these are enough reasons to switch to biomass power.

Biomass based power

Biomass is a valuable physical mass of biotic factors and ideally suited for the energy generation in different forms for the fulfillment of human demands over time. Even though deep ground fuel resources of biological origin satisfy it comprehensively, the way it is oxidized today on a time scale for energy production alarms the world by a phenomenon called “Global warming”. It forces us to scan for a suitable and sustainable alternative to fossilized biomass and the answer lies with surface dwelling, active biomass which is derived either from live or dead sources for power generation. Biomass can be subjected to power generation by combustion principle which is exactly followed for fossil sources and also is found to have a greater flexibility to generate power than conventional sources. Besides combustion, biomass is readily amenable for gasification where energy as power, heat and synthetic fuels can be derived. Biomass based power proves to be highly profitable under conditions where natural resources such as wood from forests, agricultural and animal sources etc are at abundance. India is a potential hub for this alternative route of power generation but currently holds a marginal fraction of 2650 MW out of its total installed capacity of 172000 MW. It utilizes bagasse co-generation system as its major option for biomass based power production with a capacity of 1411.53 MW achieved till June, 2010. It is important to note that biomass based power is multi-dimensionally advantageous as follows Rural economic upliftment, Suited for rural areas, Ability to have small kW scale power production, Distributed generation, Carbon neutral, Efficient utilization of renewable biological sources and accession of low cost resource.

Biomass conversion to natural gas – is this being followed anywhere?

I and my team might be working on an interesting project where the company is trying to move away from natural gas for its heating purposes and into the use of biomass for the same. The reason of course has to do with economics, with natural gas prices shooting through the roof past couple of years. While we are figuring out ways in which the company could use biomass directly for heating instead of natural gas, this process poses some problems owing to the specific needs of the client. I am hence wondering if the process of converting biomass to natural gas is being followed anywhere. I know that this is pretty much feasible, but not sure about the technology maturity and economics. If there is anyone who is aware of commercial conversions of biomass to natural gas, do let me know. You can include your response in the comment section or send a note to narsi [at] eai dot in. Thank you.

Biomass Gasification for the Environment and Economy

There are a whole lot of benefits from biomass gasification, both economy wise and ecology wise. Speaking of environmental benefits, gasification plants produce significantly lower quantities of air pollutants, which is really a good thing.  The process can also reduce the environmental impact of waste disposal because it can use waste products as feedstock, generating valuable products from materials that would otherwise be disposed as wastes. Gasification's byproducts are non-hazardous and are readily marketable and also use significantly less water than traditional coal-based power generation, and can be designed so they recycle their process water, discharging none into the surrounding environment. If that is not convincing, let us look at the economical benefits. Gasification can be used to turn lower-priced feedstocks into valuable products like electricity, substitute natural gas, fuels, chemicals, and fertilizers. For example, a chemical plant can gasify petcoke or high sulfur coal instead of using high-priced natural gas, thereby reducing its operating costs. While a gasification power plant is capital intensive (like any very large manufacturing plant), its operating costs are potentially lower than conventional processes or coal-fired plants because gasification plants are more efficient and require less back-end pollution control equipment. With continued research and development efforts and commercial operating experience, the cost of these units will continue to decrease. The process also offers wide fuel flexibility. A gasification plant can vary the mix of solid feedstocks, or run on gas or liquid feedstocks—giving it more freedom to adjust to the price and availability of its feedstocks. Many predict that coal-based power plants and other manufacturing facilities will be required to capture and store CO2, or participate in a carbon cap and trade market. In this scenario, gasification projects will have a cost advantage over conventional technologies.

Biomass Gasification in India to Generate Lakhs of Jobs

Emerging green economy in the country may see creation of nine lakh jobs in India by 2025, a top government official said.

"India could generate nine lakh jobs by 2025 in biomass gasification, of which three lakh would be in manufacturing of stoves and six lakh in areas such as processing into briquettes and pellets and the fuel supply chain," Ministry of Micro, Small and Medium Enterprises (MSME) Secretary Dinesh Rai said.

More from here.

I am not sure if biomass gasification alone could generate almost a million jobs. The secretary appears to have his numbers done for him all right, but I still wonder.

It will of course be good if it comes true. It was only yesterday that I met this gentleman whose company manufactures efficient burners for kerosene stoves and he was quite hopeful about the micro-gasifiers as well.

Let's see how it goes

Biomass Gasification Power Production – Bottlenecks and Barriers

Biomass gasification is a process where materials are transformed by thermal decomposition under partially oxygenated conditions to generate syn-gas for power generation. It seems to be a powerful technique where energy can be produced in a sustainable way along with valuable products such as green oil and biochar but it is multi step process where bottlenecks continuously arises at every step of the production pathway. The most commonly encountered limitations are batch to batch variation in  energy content, purification of the syngas, contaminants influence in the performance of the engines, ash and biochar disposals, toxic gas emissions and operational efficiency of the gas engines and mandatory modifications required to make the engines energy effective. In addition to these prime technical problems, others notable hindrances are insufficient capacity of the stakeholders and inadequate institutional and policy framework at the national, regional and local levels and limited access to financing and lack of interest on part of the state electricity boards (SEBs) in promoting biomass power generation etc. In India, conditions are further complicate by lack of working capital, limited interest in power projects, lack of effective regulatory framework and absence of effective information dissemination etc. In spite of the limitations, the technology continues to gain acceptance. Its potential to meet the energy demands on a flexible scale makes a robust move to outweigh the magnitude of limitations associated with it.

Cons of Gasifiers

The use of biomass gasification for power production is not new, but its use has been so far been limited and its contribution to the overall power production has so far been negligible in India. The producer gas derived from biomass gasification can be used for either producing power (by use in a gas engine) or can be used for thermal applications. With better technologies evolving for both gasifiers and gas engines, it can be expected that biomass gasification could start contributing a lot more to the overall power production in India. For starters, biomass gasifiers are reactors that heat biomass in a low-oxygen environment to produce a fuel gas called the producer gas. The gas produced from a gasifier can drive highly efficient devices such as gensets, turbines and fuel cells to generate electricity. A biomass gasification system consists primarily of a reactor or container into which fuel is fed along with a limited (less than stoichiometric, that required for complete combustion) supply of air. Heat for gasification is generated through partial combustion of the feed material. The resulting chemical breakdown of the fuel and internal reactions result in a combustible gas usually called producer gas. Though gasifiers are really special in their own way, they have their limitations. Gasification is a complex and sensitive process. There exists high level of disagreement about gasification among engineers, researchers, and manufacturers. Several manufacturers claim that their unit can be operated on all kinds of biomass. But it is a questionable fact as physical and chemical properties varies fuel to fuel. Gasifiers require atleast half an hour or more to start the process. Raw material is bulky and frequent refuelling is often required for continuous running of the system. Handling residues such as ash, tarry condensates is time consuming and dirty work. Driving with producer gas fueled vehicles requires much more and frequent attention than gasoline or diesel fueled vehlicles. Getting the producer gas is not difficult, but obtaining in the proper state is the challenging task. The physical and chemical properties of producer gas such as energy content, gas composition and impurities vary time to time. All the gasifiers have fairly strict requirements for fuel size, moisture and ash content. Inadequate fuel preparation is an important cause of technical problems with gasifiers. Gasifier is too often thought of as simple device that can generate a combustible gas from any biomass fuel. A hundred years of research has clearly shown that key to successful gasification is gasifier specifically designed for a particular type of fuel. Hence, biomass gasification technology requires hard work and tolerance. As I said, gasifiers are indeed special in their own way. I’d rather we just wait for the technology to advance in the future to go far beyond its limitations. After all, as I said then and I will again, petroleum is not here forever, and we need more sustainable feedstock and advanced technologies for processing.

Cool Solutions for Your Hot Problems – Getting Your Heating Costs Under Control

industrial heating boiler 1 Sustainable Industrial & Commercial Heating Solutions - A Critical Pain Point No, this blog post is not about those hot problems. It is about problems companies, especially in the manufacturing sector, face for their heating requirements! With the prices of furnace oil, diesel and LPG increasing alarmingly in the past few years, companies suddenly find their costs of their energy shooting up to unaffordable levels. Suddenly, using renewable and sustainable energy sources such as solar and biomass, and utilizing heat that was wasted earlier appear to be the way forward. I hence thought I’d provide an overview of renewable and sustainable options available for heating requirements in factories. The following are the sustainable heating avenues that are technically feasible today:

  • Solar Water Heater
  • Biomass
  • Waste Heat Recovery/CHP/Cogen
  • CST (concentrating solar thermal)
  • Energy efficiency heating equipment
  • Back pressure steam turbine
Solar Water Heaters Yes, we are talking about the simple and common solar water heaters. Could they provide a solution for industrial heating needs? The answer is Yes. Solar water heaters typically can provide temperatures up to only about 70OC, while many industries such as food and diary will require temperatures upwards of 150 deg C. This should however not be a deterrent as solar water heating can be used to preheat the water.  To the extent that solar water heaters can be used to replace furnace oil or diesel, proportionate cost savings can be derived. Taking the current prices of furnace oil, diesel, LPG or natural gas, even partial substitution of any of these fuels with solar heat makes significant economic sense. The capital cost involved in setting up this solar water heater facility can be recovered in about 2.5 years at the current prices of fossil fuels. Biomass based heating Let's consider a factory currently using about 10000 m3 of natural gas per day (or about 10,000 liters of furnace oil per day) for this discussion. Such a factory can save considerably by switching over to biomass from fossil fuels for its heating applications. The advantage with biomass based heating is that it is a firm source of energy and can technically replace the entire fossil fuel use for 24X7 operations. Biomass–based heating is a fairly old idea, but today, this can provide more bang for the buck using the gasifier technology which is a much more efficient way to provide heating than direct combustion. Essentially, combustion is not the best way to derive heat energy from biomass. Gasification, by first converting the biomass into an organic gas called the producer gas, makes the entire heating process far more efficient as it is easier to control and optimize producer gas for combustion than it is to optimize raw biomass. Using gasification also provides small amounts of charcoal as a by-product. Charcoal commands a good value in the marketplace. Today, a number of plants in India and overseas are seriously looking at using biomass for their boiler as well as their other heating and drying applications. The economics of biomass are fairly simple. At the current prices of biomass (Rs 4-5 per Kg), a 50 T per day biomass based gasification can displace about 10000 m3 of natural gas  or about 10,000 l of furnace oil. Natural gas costs about Rs 40 per m3 and furnace oil about Rs 42 per liter. Thus, biomass based heating would cost Rs 2.5 lacs per day vs Rs 4 lacs approx for either furnace oil or natural gas. This translates to a saving of Rs 1.5 lacs per day for such a facility or over Rs 5 crores per year!  The payback periods for these are in the range 2-3 years. Waste heat recovery / CHP / Cogen Utilization of waste heat has become one of the most sought after ways in the manufacturing sector today. With available technologies, it is today possible to convert both high temperature waste heat as well as low grade waste heat into useful heat or cooling. Of specific relevance here are technologies such as vapour absorption chilling, stirling engine and organic rankine cycle power generation mechanisms. While stirling engine is arguably not yet ready for large scale, reliable commercial use, vapour absorption chilling is a mature technology today, and organic rankine cycle is already a commercially available solution. VAM (vapour absorption) route will be especially useful for factories having significant cooling requirements, either in terms of air conditioning or for chilling/refrigeration. CHP/cogen is already quite prevalent in the sugar mills and distilleries in India. For those facilities that have large amounts of waste heat, CHP is a viable and financially rewarding option. Concentrating Solar Thermal Until a few years back concentrating solar heat was used predominantly for power generation – known as concentrating solar power (CSP). But today, using the same CSP technology as the base but with lesser sophistication, solutions are available that allow concentrating solar heat to generate steam up to 200OC, something that can be used in many process industries for most of their heating purposes. This has opened up the new domain of concentrating solar thermal (CST). CST is today a commercial solution and has already been adopted / implemented at many process industries in the country including diaries, food manufacturing units, large canteens and kitchens and the like. In most case, CST might not be able to replace conventional fuel use fully. It has however been estimated that it could replace up to 75% for many installations. That can be a tremendous saving for companies that are bearing the brunt of fast increasing furnace oil / LPG / diesel prices. Unlike solar water heaters, which is a highly mature technology, CST is still undergoing significant innovations, thus making it possible for companies to have high efficiency and high productivity technology installations in the near future. CST has been shown to have payback periods of less than 3 years in the installations that it is already operating in India. Energy Efficient Heating Equipment I recall a trip I made to a well-known hotel in Chennai where the chief engineer said said that by just replacing one old pump with a new, efficient one, they were able to reduce about 5% overall in electricity costs. This moral is true for many heating appliances and equipment too - be they boilers, furnaces, ovens or kilns. Of course, the decision is usually harder as the capital costs involved in changing over could be considerable, as these heating equipments will usually form the bulk of the cost of the overall heating system. Back-pressure Steam Turbine Back pressure steam turbines are not exactly for thermal efficiency or for reducing your heating costs, but I thought I’d include these here as they still provide a better bang for the buck from the heat generated. Back-pressure steam turbines essentially use the extra pressure and temperature that are inevitably present in the process steam to drive a small non-condensing turbine to generate power. The steam that leaves this back-pressure steam turbine goes on to do the useful work. As mentioned earlier, while it does not provide heat at a lower cost, it provides more value for the same amount of energy used for heating, by generating additional power from it. Summary There, you have it. Using one more of the above six avenues, factories that use significant amounts of heat can achieve significant cost savings while at the same time becoming far more “green” and environment friendly. Wish to know more on how your factory could be made more green through sustainable heating solutions? Send a note to me - Narasimhan Santhanam  ( narsi@eai.in  ).

Costs of feedstock for Biomass gasification

Biomass gasification utilizes renewable feed stocks for liberating the synthesis gas by thermal decomposition under high temperature conditions. Among the factors affecting the production protocol, cost economics play a critical role and is well pronounced in cases when the scale of operation is magnified. Entrepreneurs of gasification technology often make contracts with farmers or traders so as to ensure a price security and timely uninterrupted availability of their concerned feed commodity. In spite of the strategies, price fluctuations in gasification feed stocks have been witnessed, for instance cost of rice husk was at Rs: 600/tonne in 2009 but has steeply increased to Rs 1800/tonne by the end of 2010 and such an extreme volatility in market prices causes a concern to buyers and affect the final price of the power/unit produced by biomass gasification technology. Lack of price security has produced an unique trend in gasification where the venturers start their own farms for feed stock production which they claim that it can cut costs by two-third of the actual cost and seems to be working well in particular with dedicated energy crops. Gasification technology is well balanced economically as entrepreneurs have a scope to sell biochar by-product which fetches good market price to compensate for the cost procurement of the feedstock. Socio-economic and technical factors continuing to challenge the progression of gasification but the productivity makes it a superior choice that cannot be camouflaged.

Current Status of Biomass Gasification in India

India has initiated its power generation from renewable sources by several different principles namely gasification and combustion. Biomass gasification is carried out at different power capacity levels ranging from 25 kW to 2 MW and above. When a comparative analysis is made between combustion and gasification of biomass, the former technology is best operational under high capacity installations while the inverse is true for the gasification. This peculiar advantage seen in gasification to operate at smaller ranges makes the technology suitable for adoption in rural and by small entrepreneurs where power generation is required rather than efficiency. The technology even though best functions with high range installations of 2 MW, its utility is obstructed by the demand for a series for engines and India has less than 10 installations so far. Gasification technology is really ideal where resources are randomized and adoption of any other technology is tedious on a financial scale. Gasifiers are flexible to operate which makes the user to follow any technology depending on his requirements to a limited extent.

Decarbonizing India’s Energy Sector by Biomass and Biofuels


This post is a part of DIL Intelligence series from Energy Alternatives India (EAI), India's leading climate-tech consulting firm.

DIL stands for Decarbonization for India's Leaders and provides comprehensive market intelligence and updates to Indian corporate leaders on prominent decarbonization efforts across the Indian industrial ecosystem. DIL is provided by EAI's strategy consulting team. More about our consulting from here.


In India, 22% of the total energy supply is renewables, with biomass contributing 85%. Biomass use is shifting from traditional residential heating to power production. Biofuels represent less than 1% of transport fuels, with bioethanol at 3% of gasoline consumption. The biomass market is projected to reach INR 32,000 crore by FY2030-31. India produces 450-500 million tonnes of biomass annually, with a surplus of 230 MMT/year. Biomass-derived energy constitutes 32% of India’s primary energy use. The biomass pellet manufacturing capacity is 2.38 MMT, with 83,066 MT co-fired in 39 thermal power plants.

Reliance Industries Limited (RIL) is transitioning from fossil fuels to renewable energy, including biofuels, for its energy demand. This involves using bio-pathways to fix CO2 and recycling materials across value chains. RIL plans to set up around 100 Compressed Biogas (CBG) plants over the next five years, consuming over 5.5 million tonnes per annum of agricultural residue and organic waste. This initiative is projected to reduce nearly 2 million tonnes of carbon dioxide emissions annually. In essence, RIL’s decarbonization strategy involves renewable energy, biofuels, recycling, and CBG plants.

Thermax, an Indian energy and environment engineering company, is decarbonizing its manufacturing processes using biomass and biofuels. Its subsidiary, TOESL, installs biomass-fired plants and sells steam. Thermax’s solutions include the Atmospheric Fluidised Bed Combustion Boiler, capable of using various fuels including coal, lignite, rice husk, petcoke, spent coffee ground, washery rejects, low ash coal, paper sludge, roasted chaffs, DOB, bagasse, pith woodchips, coffee husks, mustard stalk, cotton stalk, and char. Thermax has secured an order worth over Rs 500 crore to set up five bio-CNG plants across India, with a capacity to produce 110 Tonnes Per Day of bio-CNG, utilizing local feedstock exceeding 1,000 TPD. This initiative contributes to the decarbonization of manufacturing processes.

The shift from fossil fuels to renewable energy sources is a key aspect of the company's strategies. This transition is driven by the need for cleaner energy sources and the potential economic benefits of renewable energy. Development of advanced biofuels like bioethanol, biodiesel, and biogas from sustainable feedstocks like algae and dedicated energy crops can further reduce reliance on fossil fuels and enhance energy security.

Looking ahead, the focus will be on enhancing the efficiency of biomass and biofuel technologies, developing second-generation bioconversion processes, and ensuring the sustainable sourcing of feedstocks. The potential of biomass and biofuels extends beyond just energy production. It opens up opportunities for waste management, rural development, and job creation, contributing to a circular economy. Companies like Reliance Industries and Thermax are pioneering this transition, demonstrating the viability and benefits of these renewable energy sources.

Emerging Feedstock for Biomass Power

Following my previous post on the industry perspectives on the various methods that have to be adopted for sustainable feedstock procurement (http://eai.in/blog/2011/12/industry-perspectives-and-strategies-for-effective-biomass-feedstock-procurement.html), today’s article showcases the various feedstock (emerging) that could be used as  a potential source for biomass-based power generation. As you might be well aware, the first generation feedstock such as sugars, starches from wheat, sorghum, sweet potato etc are not widely used for bioenergy production owing to the food-fuel conflicts. Similarly, even the second generation feedstock such as mustard are not being used in a big way for bioenergy production. These days, more focus is being thrown on the advanced feedstock such as the third-generation biofuels ( these seek to improve yields through improving the feedstocks themselves instead of the processes). These feedstocks include those sources that promise to generate greater than 500 gallons of oil per acre per year. Examples include palm oil and algae oil, rapeseed and jatropha oil, grasses (switchgrass, miscanthus), trees (willow), halophytes (saltwater plants). Provided are some details of the emerging biomass feedstock such as camelina, miscanthus and bamboo and their potential to perform as a bio-fuel. Miscanthus: Miscanthus, also known as Elephant grass can grow up to 3 meters high and it is native to tropical and sub-tropical regions of Africa and South Asia. Miscanthus is mentioned as a biofuel crop because of its relatively high dry matter yields across a range of environmental and soil conditions. The Miscanthus genotype most commonly recommended for biofuel production is a sterile hybrid (Miscanthus x giganteus) believed to be a M. sacchariflorus x M. sinensis hybrid. Miscanthus utilization in the biofuel industry is primarily for combustion in power plants – it has the desirable properties of low water and ash contents. Current research is focused on its potential as a biomass crop for direct combustion and for lignocellulosic conversion to ethanol. Giant miscanthus has been studied in the European Union and is now used commercially there for bedding, heat, and electricity generation. Most production currently occurs in England but also in Spain, Italy, Hungary, France, and Germany. Recently, Japan and China have taken renewed interest in this native species and started multiple research and commercialization projects. In the United States, research began at the University of Illinois at Urbana-Champaign in 2001 and has expanded rapidly to other U.S. universities. However there is currently little published information on giant miscanthus yields in the United States. Bamboo: Recently, bamboo has received increasing attention for producing biofuel because of its easy propagation, vigorous regeneration, fast growth, high productivity and quick maturity. Bamboo is an efficient user of land, and produces more biomass per unit area than most tree species. But the process of converting bamboo cellulose into liquid fuel is difficult to execute efficiently because of the extraordinary density of the plant.  However, new research from Mississippi State University hold clues for how scientists can learn to more easily break down bamboo, and thus more efficiently extract biofuels from all other cellulose sources using the bacteria from pandas’ waste. If the researchers are successful, the manufactured enzymes could be used in a new, much cheaper and more efficient process for converting bamboo and other woody plants into biofuels. Fuel properties and potential as a bio-fuel of different bamboo species:

Species Moisture content Density Ash content Energy content
% g/cm3 % MJ/Kg
B.pallida 44 0.61 1.91 18.63
B.tulda 37 0.65 1.92 18.61
D.asper 37 0.77 4.23 17.92
D.membranaceus 43 0.62 4.99 18.81
G.apus 35 0.76 2.00 18.14
Camelina Camelina, an oilseed, is a rotation crop for wheat that can be established on marginally productive land. It is an annual, short season plant. Biofuel from camelina is an ideal jet fuel substitute. Camelina has a number of advantages over its competitors, including using far less water, thus allowing it to be grown on marginal land, thereby not taking food acreage out of production. Furthermore camelina has a relatively short growing season of 80 to 100 days, requires no special equipment to harvest, and the silage remaining after processing can be fed to livestock and poultry, with the added side benefit of increasing their omega-3 production. Camelina is increasingly emerging as a prime biofuel source and thus attracts investment worldwide, as global demand for aviation fuel for passenger flights is now more than 40 billion gallons annually. In the earlier of this year, USDA announced two Biomass Crop Assistance Program (BCAP) project areas devoted to developing camelina as biofuel in several states, including Montana. USDA's Risk Management Agency (RMA) has also recently announced a new pilot program of insurance for camelina beginning with the 2012 crop year.

Future Feed-in-Tariff Trends for India – for Wind, Solar and Other Renewable Power Sources

It is an open secret that renewable power requires incentives - these usually are in the form of capital subsidies, tax incentives and most importantly, via feed in tariffs. It is a million dollar (make that Billion Dollar) question what the future of feed in tariffs will be for the mainstream renewable power sources. I picked up some resources on these. Wouldn't say they provide a peek into the future, but at least one of these try telling us how the government arrives at these numbers, so that will provide us with some clues.

How Biogas-based Power Generation is Picking up Pace in India

===========================================

Are you looking to get energy security for your company through reduction in the use of diesel, furnace oil, LPG and costly grid power? EAI can do a feasibility study for the use of solar PV & thermal, biomass for heat and power, waste heat recovery and energy efficiency to dramatically cut down fossil fuel use and reduce your energy bills. See EAI's SURE-FIRE offering for more.

 ===========================================

 Most of us have come across the gobar gas – literally meaning gas from the cow. It is the same as what is called biogas. This is the gas that is released when bacteria feast on organic matter – typically human and animal feces – and release a gas that is about 50% methane. While biogas had predominantly been used earlier for heating purposes, its use for power production is also beginning to show a marked rise across the world, and in India too. How is power produced from biogas? The process is actually quite simple. Step 1 is generation of biogas. This is done typically using what are anaerobic called digesters. Animal (or human) waste is fed into the digester, where the microorganisms (called methanogenic bacteria) act upon it. Depending on the type of digester, it could take anywhere between 10 days to 15 days for the waste to have been "digested" by the bacteria and the release of biogas. The biogas thus produced can be used in IC engines specially devised for the use of biogas. These engines are similar in working principles to diesel engines and natural gas engines. These engines produce electricity from biogas. A bit of observation will lead us to easily understand why this concept will be of enormous interest to specific industry segments. Two segments stand out - industries that employ large numbers of animals and sewage treatment plants that treat human waste. Both these segments have started benefitting from this concept; as a result, we have a few STPs (sewage treatment plants) already generating power from the sludge generated (one of the STPs at Chennai, at a town called Nesapakkam, generates about 500 kW of power from the waste, and uses the power generated for all its electricity purposes). Some numbers will help understand the potential available for power generation from biogas. The cow population of India (about 225 million) alone generates about 800 million tons of wet dung which translates to about 150 million T of dry weight. 1 Kg of dry cow dung can generate about 1.2 kWh of electricity (it can generate the equivalent of about 4 kWh thermal). Thus, if all cow dung were converted to electricity, that would be 1.2*150*1000 million kWh = 180 TWh. India generated a total of 855 TWh in 2011-12. This implies that cow dung, if entirely converted to power, would have produced about 20% of total India's power! If the waste of other cattle and human waste were also taken into account, this could be about 30%. That is an awesome number. Of course, these data hide the actual difficulty in converting even a small portion of animal or human waste into electricity, owing to the infrastructural and social problems associated with these. All the same, waste -> biogas -> power is quite practical to a whole host of industries for whom such waste is available on premises. More information about waste to energy in general in the Indian context, is available from EAI's waste to energy resource section.

Agricultural residues never go to waste. Not when they can be used for generating energy. In this context, the government of Punjab, India, plans to produce about 1,000 MW of green energy from livestock residues by 2015. When you think about it, this has huge economical and environmental benefits. In a region where large quantities of cattle manure become a major pollutant, this could be seen as an opportunity that could open a lot of doors. Aside livestock residues, the state also generates nearly 21 million tons of rice stalks and similar biomass plant wastes annually, which can all go into the production of green power. The state government is thus planning to make renewable resources as the source of their power to contribute 10% of its total energy production in the next five years. It is worthy to mention that Punjab already runs a biomethanation facility with a capacity of 1 MW, in a location close to Ludhiana. The facility uses methanogens (microbes that produce methane as a metabolic by-product) for the manufacture of methane gas. It currently uses 235 tons of cattle wastes to generate 18,000 kWh of electricity in addition to producing 45 tons of organic fertilizer every day. Also, the Punjab Energy Development Agency has developed 318 MW of green power projects, which includes the Ludhiana plant, till date. These projects comprise 37 MW of small hydro facilities, 28 MW of biomass power facilities, 250 MW of biomass co-generation facilities and 2 MW of solar projects. The agency also develops 132 MW of green power projects currently, which include 11 MW of hydropower, 100 MW of biomass co-generation and 20 MW of traditional biomass. If everything goes right and operational, the state will generate 700 MW of green power by 2012. That’s big! It is worthwhile to note that the planters are also getting an income of nearly RS. 4,000 per acre every year in the process of marketing agro wastes to biomass facilities.

Industry Perspectives and Strategies for Effective Biomass Feedstock Procurement

===========================================

Are you looking to get energy security for your company through reduction in the use of diesel, furnace oil, LPG and costly grid power? EAI can do a feasibility study for the use of solar PV & thermal, biomass for heat and power, waste heat recovery and energy efficiency to dramatically cut down fossil fuel use and reduce your energy bills. See EAI's SURE-FIRE offering for more.

 ===========================================

One of the most critical bottlenecks for biomass power plants is the supply chain bottlenecks that could result in non-availability of feedstock. A related problem is the volatility, or more precisely increase, in the feedstock price. Both these could render the project unviable. Highlighted in this article are some of the industrial perspectives in overcoming barriers for procuring a balanced feedstock supply. EAI’s research with industry experts suggest that there is no established biomass value chain that exists in India for the procurement and transportation of the biomass feedstock. Typically, the facility staffs  from a biomass gasification plant acquires biomass from several to dozens of small-scale biomass suppliers on a relatively informal, non contractual basis; although some have considered the use of aggregators, there is no data or proof available from the Indian biomass gasification companies that have engaged such a service as yet. The biomass procurement model that is typically followed in India is discussed below: Route #1 – Biomass Producer -->Transport Contractor --> Biomass Collection Centres (BCC’s) --> Power Producers The biomass producer i.e. the farmers/mill owners hands over the feedstock to a transport contractor who in turn delivers the feedstock to the biomass consumers or BCC’s. The BCC’s (managed by the biomass consumer) pay the farmers and the power producers collect the feedstock from these collection centres as and when required. At some instances, the farmers deliver the feedstock in the power producer’s facility and get directly paid for it. Route #2 - Biomass Producers --> Waste Processing Mills -->Biomass Power Producers For feedstock where further processing is required, the farmers/mill owners deposit the feedstock in waste processing mills. From the waste processing mills through a transport contractor the feedstock is deposited in the BCC’s or directly in the power producer’s facility. In some cases, especially in briquetting, the processing is done in the collection centres itself where a mobile briquetter is taken and the briquettes that are processed are directly delivered to the facility or collected by the power producers. Key Strategies to be Followed for Effective Biomass Feedstock Procurement EAI’s interactions with the industry reveal that the following strategies have to be adopted   in order to bring both the availability and price of biomass under control:
  • Security should be addressed by obtaining a written formal supply agreement with a reputable, local supplier. A five-year signed supply agreement with pricing and minimum volumes can go a long way in helping to secure necessary financing. A bioenergy project that is totally reliant on only one source of feedstock will be at risk, so two supply contracts are even better. This will also allow one to negotiate a better feedstock price, as the supplier will benefit from a long-term relationship and a guaranteed market. An interested lender needs to know that both the feedstock supplier and bioenergy processor are committed to the project.
  • It can be beneficial to hire an independent professional to verify one’s biomass supply projections and double-check that the feedstock supply is sustainable over the long term
  • Backward integration and own captive biomass source (one company, Orient Green Power, is even trying out a novel technique of going for energy plantations on their own wind farms)
  • According to the Washington based biomass supply company ‘Powerstock’, for a well-managed supply, an inclusive definition of biomass is needed. The company is also taking efforts to educate the public on the value of well-managed, productive forests.
  • The bottom line of feedstock security is composed of several aspects: grower relations, harvesting, marketing, equipment utilization, proprietary techniques and agricultural economics. Hence it's important to manage the entire process from seed to market.
  • The supply sector needs to make the transition from a residues-based approach to an integrated, dedicated feedstock supply system using energy crops, plus residues.

Potential for Biomass Power in India

Biomass based power generation is a choice of reality under the geographical regions where a sustainability exists in the flow of biologically raw materials for the production of power and India is one of the most notable universal giants for the production of biomass based power which can be best understood from the estimates of its biomass availability and the power produced from it. India has biomass production of 546 million tonnes per year from the agricultural sources alone to generate electricity at a capacity of 17,982 MW and its overall production of power from renewable sources stands at 34961 MWe in 2010.A calculated annual growth rate for the next decade realistically and optimistically is above 42,000 MWe and 48640 MWe respectively. The development of biomass based power is further enhanced by the Government regulatory policies by declaring duty exemptions’, tax breaks and financial incentives etc. The cost of producing electricity from biomass is affordable at Rs: 2.25-3.25 / kWh. In spite of all these attempts biomass based power generation is at its infant stage because of hindering factors such as feedstock availability, transportation, price volatility etc. India to emerge as a role model must utilize its renewable energy sources to a large extent, develop dedicated energy crops, establish end user market for co-products such as charcoal, biochar, activated carbon, and implement energy efficient technology for economically feasible power generation on a massive scale.

PRESPL Secures ₹4.1 Million Investment from Mitsui for Biomass Growth


This post is a part of Climate G2I Intelligence series from Energy Alternatives India (EAI), India's leading climate-tech consulting firm.

G2I stands for Gateway 2 India, and provides comprehensive market intelligence and go-to market assistance for International firms entering the Indian climate-tech market. More about Climate G2I from here


Mitsui, a leading Japanese conglomerate, has recently invested ₹4.1 million in Punjab Renewable Energy Systems Pvt. Ltd. (PRESPL), a company focused on collecting agricultural residues and converting them into biomass briquettes and pellets. This investment underscores the growing potential of the Indian biomass sector, which is expected to witness significant growth in the coming years.

The Indian biomass market is estimated to be valued at around ₹50,000 crore and is projected to reach ₹1,00,000 crore by 2025, driven by factors such as the Increasing demand for renewable energy, Growing awareness of environmental concerns, and  Supportive government policies.

The Indian biomass sector is also witnessing a surge in international collaborations, with several prominent companies entering the market through partnerships and alliances. For instance,  Aramco, a prominent oil and gas company, joins forces with ReNew Power, India's largest renewable energy company, to explore opportunities in developing and deploying low-carbon technologies, including biomass-based power solutions. This collaboration signifies the growing interest of leading energy giants in exploring cleaner alternatives. 

Additionally, Danish Biogas's collaboration with the Maharashtra Energy Development Agency (MEDA) brings together expertise in advanced biogas technologies with experience in promoting renewable energy and rural development in Maharashtra. This partnership contributes to a more sustainable waste management system through biogas generation..

These strategic partnerships are just a glimpse into the exciting developments propelling the Indian biomass sector forward. The government is also playing a crucial role in accelerating its growth through supportive initiatives like subsidies for setting up biomass power plants and briquette/pellet production units, promoting dedicated energy crops and efficient residue collection systems, and providing tax benefits for biomass projects. Investments in research and development are also being made to improve conversion technologies, optimize feedstock utilization, and develop cost-effective biomass solutions.

Navigating this complex ecosystem requires a comprehensive understanding of the key players involved. The Indian biomass value chain comprises various stakeholders, including biomass producers like farmers and forestry companies, collectors and aggregators responsible for managing feedstock collection and storage, processing and conversion companies that transform biomass into usable forms, original equipment manufacturers (OEMs) who create machinery for the sector, suppliers providing essential goods and services, power plants and industries utilizing biomass-based fuels, and government agencies responsible for regulation and promotion.

Beyond the core value chain, the adjacent value chain plays a crucial role in supporting the sector's growth. This includes financial institutions offering loans and investments for biomass projects, research institutions and universities engaged in R&D advancements, and non-governmental organizations (NGOs) promoting sustainable practices and advocating for policy changes.

Indigenization remains moderate to low currently, with reliance on imported technologies and equipment. However, government initiatives and rising demand are expected to gradually increase domestic capabilities in the coming years.

Primary Routes for Power from Biomass

The three primary routes for biomass to power are: Combustion, Gasification and Anaerobic Digestion. Combustion is easy to understand – instead of using coal or other fossil fuel, use biomass to produce steam that runs a turbine. Combustion of biomass for power could either be in the form of co-firing (when it is burned along with coal) or pure play biomass based combustion. In the case of gasification, the biomass is first gasified and this gas turn produces power in a gas engine. Anaerobic digestion is usually applied to biomass that typically have a high amount of water in them (anaerobic digestion is most used for treating organic waste such as kitchen waste and sewage waste into energy). Under this route, microorganisms act upon the organic matter present in the biomass under anaerobic (absence of air) and convert it into biogas. An emerging route for biomass based power is pyrolysis. In this, the biomass is rapidly heated to 450 - 600 °C in absence of air, and results in a bio-oil called the pyrolysis oil, which can in turn be used for firing the boilers. Typically, 50 - 75 % (by weight) of the feedstock is converted into pyrolysis oil. Pyrolysis as a method for power production is not well established currently in India or elsewhere in the world. Typically pyrolysis plants work well beyond 2 MW scale, while gasification plants work well until 2 MW scale, at the current technological progress. Thus, it can be said that pyrolysis takes off where gasification ends. Also check out: EAI Consulting for Bio-energy & Biofuels, Bioplastics & Other Biomass-based Value Added Products

Prominent biomass feedstock for gasification

Biomass for power generation by combustion or gasification is normally variable in its chemical composition of electron rich reactants, ash content, moisture, sulphur and nitrogen content etc. As a result, selection of the most convenient feedstock is an issue of debate. The degree and diversity of contaminants strongly influence the production and purification of synthesis gas in gasification while they tend to have a minimum effect in the combustion process. Independant of these disturbances virtually any raw material applied in power generation process should be a matter with potentials. In India, a vast array of feed stocks are utilized for power generation but the most wide ones are farm and mill wastes, woody trees, energy plantations and other green manure crops. Preference is made on the basis of availability, cost, bulkiness of the material, pre-processing, storage etc. Biomass used in India yields varying level of energy but it is also the gas engine and generators whose efficiency equivalently determine power generation.

REC Price Band Revised

The Central Electricity Regulatory Commission(CERC) has announced the floor and forbearance prices to be used for solar/non-solar projects from the FY 2012-13 upto 2016-17. The prices set are shown in the table below

Non Solar (Rs.) Solar (Rs.)
Prices (2012-2017) Current % Reduction Prices (2012-2017) Current % Reduction
Forbearance Price 3300 3900 15.38 13400 17000 21.18
Floor Price 1500 1500 0.00 9300 12000 22.50
Background Earlier, the CERC had proposed a few changes (refer table below) to be made to the REC prices and invited comments/suggestions on the same.
Non Solar (Rs.) Solar (Rs.)
Proposed Current % Reduction Proposed Current % Reduction
Forbearance Price 3480 3900 10.77 13690 17000 19.47
Floor Price 1400 1500 6.67 9880 12000 17.67
  The final prices to be enforced from April 2012 were arrived at after considering the comments/views of stakeholders and participants at the public hearing on the proposed floor and forbearance prices. As can be seen, the final prices decided upon are considerably lower than the earlier proposed prices. Analysis Financial feasibility studies of power plants under the REC mechanism almost always consider the floor price for calculating returns. With this in mind, the evaluation of REC for the primary renewable energy generation systems looks quite healthy.
  • Non-solar – the floor price remains unchanged. Thus biomass/wind generators are expected to get the same minium revenue as they have been getting earlier.
  • Solar – the floor price has seen a cut of about 23% from current levels. Although this might seem drastic, it is not likely to have a significant impact on solar power projects (refer section below).
  APPC – Non preferential tariff and REC CERC stipulates that for a project to be eligible under the REC mechanism, the power producer has to sign a PPA with the state utilities at a price equal to the APPC price. The APPC price for a state for a particular time period is determined by the State Electricity Regulatory Commissions(SERC). Looking at the current APPC prices in various states, a combination of REC and a PPA signed at APPC rates seems comparable with the preferential PPAs signed with the state utilities. For example,  let us consider a solar PV plant to be setup in Tamil Nadu where the APPC price for 2011-12 is Rs. 3.38/kWh. Under REC regulations, if a RE developer were to get the floor price for the solar REC, the income for the solar PV plant would be Rs. 12.68 /kWh (Rs. 3.38 + Rs.9.3). Another case is Rajasthan, which has a very high potential for solar PV – where the income would be Rs. 11.9 /kWh. In comparison, under the phase 1 (batch 1) of JNNSM, the average price settled on through the reverse bidding process was  about Rs. 12.5 per kWh. As can be seen, these prices are comparable to tariff set through reverse bidding under batch 1 of the JNNSM scheme. Prices can only go higher APPC prices are set based on the cost of power generation from fossil fuel based power plants. It is highly likely that this price would increase in the future due to the increase in fossil fuel prices and scarcity of supply. This ensures that the APPC prices would continue to increase for the foreseeable future, thus ensuring higher year on year returns under the REC mechanism provided the PPA signed with the state utilities has provisions for purchase at floating APPC prices rather than fixed price. The table below gives a comparison between preferential tariff (reverse bidding under JNNSM) and REC mechanism for a plant in Tamil Nadu. The following assumptions were made for the sake of calculations
  • Average bid price under phase 1 batch 2 of JNNSM could be around Rs. 12.5 /kWh(on the higher side)
  • APPC prices could rise by 15% annually (base price used is that of Tamil Nadu) - reasons for this were mentioned earlier.
  • REC price after 2016-17 period (i.e. from FY 2017-18 onwards) is reduced by 25%
 
Year 2012 2013 2014 2015 2016 2017 2018 2019 2020 2021
JNNSM Tariff (average) (Rs. per kWh) 12.5 12.5 12.5 12.5 12.5 12.5 12.5 12.5 12.5 12.5
APPC (Rs. per kWh) 3.38 3.89 4.38 5.04 5.38 6.19 6.38 7.34 7.38 8.49
REC (Rs. per kWh) 9.30 9.30 9.30 9.30 9.30 6.98 6.98 6.98 6.98 6.98
Total (Rs. per kWh) 12.68 13.19 13.68 14.34 14.68 13.16 13.36 14.31 14.36 15.46
REC mechanism's Incremental revenue over PPA(Rs. per kWh) 0.18 0.69 1.18 1.84 2.18 0.66 0.86 1.81 1.86 2.96

Table: REC vs preferential PPA for 10 years post 2012

As can be seen from the above table, the REC mechanism is quite comparable, if not better when compared to the assured tariff provided by NVVN over 10 years of operation of the solar powerplant. Overall, the REC mechanism can clearly drive the solar market, provided the Renewable Purchase Obligation (RPO) is strictly enforced by the various SERCs. The CERC release can be found here.   Also check out: EAI Consulting for Bio-energy & Biofuels, Bioplastics & Other Biomass-based Value Added Products

REC Trading – November 2011

The REC trading for the month of November concluded yesterday. Figures reveal that the trading has increased significantly both in volume of RECs traded as well as the price. In total 105,527 RECs were sold. Keeping with the trend of previous months, IEX had a higher share of the market with 96,154 (90%) RECs traded while PXIL saw trading of 9,373 (10%) certificates. The large volumes of trading indicate that the obligated entities are trying to fulfil their RPO as soon as possible as REC prices are showing an upward trend. The price of REC varied between the two exchanges - IEX and PXIL. Non-solar RECs closed with a price of Rs. 2,900 at IEX while the RECs sold at Rs. 2,800 at the PXIL. At the IEX, the prices have seen a 7% rise over those paid last month where the trading price was Rs. 2,700 per REC.

PXIL 51,199 9,373 2,800 0 - -
Total 308,777 105,527 - 43 - -
Interestingly, there are 43 buy bids for solar REC; this suggests that the solar REC market is gathering steam. This growing interest suggests that solar projects being planned based on REC may soon be bankable and we could see a trend in developers going for the REC mechanism during the interm period between now and the second phase of the National Solar Mission. Solar developers have another reason to rejoice as well as maintain a shrewd view on the Solar REC market. This month saw the accreditation of the first Solar project under the REC mechanims - an 8.5 MW solar project located at Jalgaon, Maharasthra developed by Jain Irrigation Systems. This project's viability has to be closely followed over the coming trading sessions as the REC certificates generated from the project slowly start coming up for sale. In total there are about 244 projects registered under REC with an aggregated capacity of 1551.92 MW (this excludes the lone solar project that recently got accredited). Conclusion The REC market continues to impress with higher sale prices and volumes. The REC prices are expected to rise over the coming months given the fact that there only 4 months left for RPO compliance. However, the price as such is expected to rise only gradually and not at the high rates seen over the year. The registration of a solar project under the REC mechanism might open the flood gates for more solar projects depending on the performance of the solar RECS. This could lead to a pradigm shift in the solar project development in India, which up until now has looked up to the state/central solar policies as the only source for project viability thereby reducing the cost of solar power in India and accelerating the road to grid parity.   Also check out: EAI Consulting for Bio-energy & Biofuels, Bioplastics & Other Biomass-based Value Added Products

REC Trading – September 2011

The REC trading for the month of September concluded recently. Trading figures reveal that the trading has increased significantly both in volume of RECs traded as well as the price. In total 46,362 RECs were sold. Keeping with the trend of previous months, IEX had a higher share of the market with 41,385 (89%) RECs traded while PXIL saw trading of 4,977 (11%) certificates. The large volumes of trading indicate that the obligated entities are trying to fulfil their RPO as soon as possible as REC prices are showing an upward trend. The most encouraging part of the trading was the price paid for each certificate. The price of REC grew to Rs. 2300 from Rs. 1800 last month.

Interestingly, there are 7 buy bids for solar REC; up from the lone buy bid last month, although this is promising, it highlights a serious issue. As with the previous months, there are no solar RECs available as no projects are registered under REC. This is a worrying trend and is going to put immense strain on the obligated entities to fulfil their solar RPO. The reasons for lack of solar projects registered under REC could include

  • Higher payback period for solar projects
  • REC prices guaranteed only up to 2016-17
  • A combination of the above two greatly reduces the bankability of solar projects
Conclusion The increase in REC trade volumes and price is very encouraging. It shows that the mechanism is a viable revenue route for developers who have not signed any preferential PPA. The demand for REC certificates is bound to keep increasing as more and more obligated entities try to fulfil their RPO in the short time span available. This is scheduled to push the REC price even further which in turn could lead to REC prices hitting their forebearance highs in the coming months. Finally more effort needs to be put in to ensure that there is sufficient supply of solar RECs in the market.

Renewtech India 2011 Conference – Day 2

The details of the first day of the conference is available here. The second day of the The 3rd International Expo and Summit, Renewtech India 2011 conference started with a speech by Mr. D.C. Bhishikar, Managing Director, Clarke Energy India. The topic was “Application of Gas Generated from Waste Treatment for Combined Heat and Power(CHP) Solutions using GE Jenbacher Gas Engine Technology” He mentioned that the company has about 300 MW of installation base in India. He explained the various aspects of the Jenbacher Gas Engine Technology and explained that while a combustion based power generation(ranking cycle) has an efficiency of approximately 28%, the Gas engine technology has an efficiency of about 40%. The next speaker was Mr. Ravinder Tanwar, VP-Operations, Websol Energy Systems Ltd and he spoke on the topic “ Rural Electrification in Sagar Island through off Grid Solar PV Power plants”. In this session, Mr. Tanwar presented a case study of how an off-grid solar PV power plant in the Sagar island in Sunderbans, West Bengal changed the lifestyle of the inhabitants there. He explained the cost of setting up the plant and the challenges that Websol faced in putting up these plants. For example, the Solar PV modules had to be transported to the islands using boats.

-

The next session was about “Solar Energy & Hybrids”. This session had speakers from Gadhia Solar Energy Systems, HCL Technologies, Soltigua-Italy and Mahindra Cleantech Ventures. Mr. Badal Shah, MD of Gadhia Solar, spoke about Solar Air conditioning. He briefly explained the principle behind how it works. He also talked about Solar cookers and highlighted the company’s projects in cooking meals at Tirupati and Shirdi temples. One key point he wanted people to remember was that Solar energy can only complement other sources of energy and cannot be a substitute for them.

Rice husk used for power in one of India’s poorest states- A case Study

Whoever thought rice husk can generate power needs a medal! Considering how much rice husks go to waste in a country where rice is the staple food, it is comforting to know fossil fuels are not our only resort for power production. Thanks to Manoj Shinha, a renewable energy entrepreneur pioneered using discarded rice husks as biomass to provide energy to Bihar, one of India’s poorest states. Mr. Shinha along with his colleagues Gaynesh Pandey, Ratnesh Yadav and Charles W. Ransler developed Husk Power Systems to address the situation of poverty in their home state of Bihar. Many villages in India live off the grid in the darkness, this new advancement means that they need not depend on grid for electricity, rather generate their own clean, affordable electricity.The company generates and sells electricity for a price that is less than half of what the villagers pay for kerosene. This was possible because the whole concept is focused on research and development investment to simplify energy production and transmission, such as using bamboo instead of cement posts to install power lines.And, since communities no longer use kerosene, wood or dung for electricity, this way of electricity generation lowers the environmental and health hazards. In addition, rice husk ash, a byproduct of the gasification process, can be used for concrete production thus reducing the amount of high-carbon Portland restless leg syndrome cement.On average, a single power plant serves 400 houses, replacing 42,000 liters of kerosene and 18,000 liters of diesel yearly. As of August 2010, H.P.S. has sequestered 50,000 tons of carbon dioxide. Currently, they have installed over 60 mini-power plants that are 100 percent biomass-based which supply power to over 25,000 households in more than 250 villages.With the market opportunity in mind, they aim to expand their business to bring clean electricity to Indian villages by installing 2,000 new plants by 2014 beyond Bihar.

Tamil Nadu’s Biomass Power Plans – Energy Plantations is the Answer?

Biomass is one of the renewable energy domains in which Tamil Nadu could have significant potential for progress in future. Estimates suggest only about 10% of the potential has so far been utilized. Of course, the lack of a robust supply chain that make create supply and price security is a problem as much in Tamil Nadu as it is in the rest of the country. Some inputs and updates for biomass power in Tamil Nadu are provided below.

  • Potential for Biomass based power in Tamil Nadu is 1589.9 MW (1160 MW based on agricultural waste and 429.9 MW from forest and wasteland cultivation).
  • 22 biomass power plants with total installed capacity of 169 MW are in operation.
  • Ten biomass power plants with totaling to 120 MW, with over 80% plant load factor, have faced temporary shut downs owing to unviable tariff rates and increasing feedstock cost.
  • Biomass power producers association has approached Tamil Nadu Electricity Regulatory Commission (TNERC) with a request to revise the tariff and offer higher annual tariff escalation. The viable rate for operating biomass power plants in years to come would run beyond Rs 6.50/kWh, but the current tariff of Rs 4.5/kWh is in no way adequate to sustain the projects in the long run.
  • Tamil Nadu Energy Development Agency (TEDA), along with Tamil Nadu Biomass Power Producers Association, has been actively involved in promoting large scale energy plantations in marginal / waste land in the state with high potential crops.
  • The Tamil Nadu Biomass Power Producers Association suggests that energy plantation would not only serve to provide cheap and continuous feedstock supply for power plants, but it would also improve the quality of life of the rural population. Estimates suggest that a 10 mw biomass power plant can ensure livelihood of over 2,000 marginalised families. They can be employed in collection, transportation, cutting, chipping of biomass and cultivation of wasteland with energy plants like Juliflora, Bheema Bamboo etc.
So, it looks like Tamil Nadu is betting significantly on energy plantations for a viable biomass power sector. Let’s hope they have got it right. Also check out: EAI Consulting for Bio-energy & Biofuels, Bioplastics & Other Biomass-based Value Added Products

The man propelling the bio-energy movement in India – PRESPL

Welcoming Lt Col Monish Ahuja to CLIMAFIX SUMMIT 2022 - the 1st summit for Indian climate tech startups. I'm sure you have heard the saying, "Water, water everywhere, not a drop to drink" That applies quite well to the Indian agricultural residues as well. Hundreds of millions of tons of agro waste around the country, but very little available for the industries to use. And worse, a good portion gets burnt on the fields because the farmers do not know what to do with them. So where's the challenge? What is broken in this system? To a significant extent, logistics, or rather the lack of it. Securing and transporting millions of tons of agricultural waste from hundreds of thousands of farmers and transporting it reliably to end users is not rocket science. But it is systems science. Discipline science. Or patience science, if that term is more endearing to you. In EAI's decade long work in the bio-energy sector during which we consulted for dozens of clients including the likes of GSK (#Horlicks division, now part of Unilever), we have seen how unorganized the agro-waste supply has been, except for bagasse coming straight from large sugar mills and to a lesser extent saw dust from plywood factories. It is a complex challenge of logistics, societal & local traditions, and of course the omnipresent politics. The sector needed someone who could wade through all these, build an efficient system and evolve an organized biomass supply chain. Enter Lt Col Monish Ahuja. Army discipline, Systems thinking. Business acumen. These characteristics have helped him build Punjab Renewable Energy Systems Private Limited (PRESPL) into a force to reckon with countrywide in industrial biomass supply. PRESPL is today is one of the few organized players that has the ability to provide industrial decarbonization on scale through biomass, supplying thousands of tons of agro-waste based biomass every day to industries. I remember sitting with him in his office in Navi Mumbai a few years back when he patiently took me through the process by which he was building an effective front-end logistics system while also putting together a scalable digital back-end system. While coming out from the meeting, I thought - finally, here's someone who appears to be just what the doctor ordered for India's bio-energy sector. Since then, his company has - not surprisingly - grown and grown. Hats off to Monish, and we are proud to have him as one of the experts who will share his insights at the CLIMAFIX SUMMIT 2022, India's first climate startup summit, Nov 25 & 26, Chennai, organized by the Climate Startup Intelligence division CLIMAFIX of EAI (Energy Alternatives India) & Energy Consortium - IIT Madras Welcome Monish, and here's hoping you inspire more of your breed - and soon.

VC / PE Perspectives and Opinions on Biomass Power

Indian VCs have not really done a good amount of investing in cleantech. Cleantech perhaps  is not really a VC game as it is more of an engineering related discplie that does not offer the types of scalabilitiees that VCs desire or the exit periods. VCs also do not understand cleantech well enough to take calls. Many cleantech deals, especially in the power segment, are PPA based, with limited upsides, not typical VC games. Many cleantech and renewable energy startups require capital that is much higher than what VCs can typically offer to invest. Predictions for Cleantech VC in 2011 - Kachan & Co.'s Dallas Kachan looks at what 2011 will have in store for cleantech (http://alwayson.goingon.com/node/66783 ) Sustained worldwide venture capital investment will continue to cede importance to corporate and non-institutional capital. A return to early stage venture investments - predict a return to early stage venture capital investing in cleantech in 2011. Energy efficiency emerges as the clear rock star of cleantech. Biofuel investment could reach former highs. Recycling and mining will attract more investment. Natural gas emerges to threaten solar and wind for utility renewable power generation. China becomes the most important market for cleantech: if you're not selling in China, you won't matter. There is a significant amount of interest among PEs for investments in both traditional and renewable energy. PEs – not surprisingly – are not very keen on risky technology bets in renewable energy, but are OK with business model risks. Some of the PEs (such as IFC, ADB etc) are willing to take fairly long-term views (with over 10 year horizon). Investment sweet spot ( in terms of the quantum) varies from fund to fund, but obviously for most of the blue-chip, it is upwards of $50 million. PEs are well aware of the regulatory and societal bottlenecks that could arise in large-scale energy sector investing (especially for coal-based and large-hydro based sectors). Many PEs are clear that they wish to invest in businesses that can stand on their own revenues (even if takes a while) and are not keen on business plans that rely on getting bought out. Most every PE acknowledged that while they might not like coal, it is here to stay as the largest contributor to power for the foreseeable future. PE arms of organizations such as IFC and ADB, while not shutting out the option of investing in coal-based or natural gas based power plants, have a mandate to decrease their exposures to these “non-green” sectors. What a PE can bring to the table - Many private equity funds have been able to provide not just the financial support required but also strategic support and value-add for the firm’s growth. Disconnect in Valuation expectations - one of the issues faced by PE players while investing in cleantech companies is the disconnect in valuation expectations between the entrepreneur and investor with the buoyant public markets resulting in an increasing buoyancy in expectations! PEs feel that entrepreneurs should take a longer term view while setting their valuation expectations. Currently, 80% of infrastructure projects, and 46% of power projects, are funded by the banking system. So, PEs constitute only a small share of the infrastructure projects. While private equity folks could like IRRs of about 25%, power and infrastructure IRRs is only about 12%. Some private equity companies might wish to play a consolidator’s role as well where they consolidate a diverse portfolio of (say) energy companies such that they win even if 7/10 companies do well enough. Investors such as IFC have specialists/experts in every project to take care of social and environmental aspects. Private equity funds are interested in the macro factors (demand supply gap in electricity et al) as well strategic micro factors. One of the factors that seem to interest PEs is the method for companies to go diversified on green power that is having assets in wind, small hydro, biomass etc together, instead of betting just on one thing alone.

Why Biomass for Power Generation?

Biomass has been used as a source of energy right since mankind started its existence; In fact, one of the predominant energy sources today is biomass. Biomass as a source for power production is not entirely new either. Biomass has been used, in the place of coal, for steam generation at power plants, though in a limited way. Indeed, currently, the predominant method used for producing power using biomass still is the combustion route, At the same time, other processes, such as biomass gasification, which can work at much smaller scales and use the biomass more efficiently are emerging. The newer processes especially biomass gasification based power production, is relevant today especially in the Indian context mainly because of its potential to provide distributed power at rural level, especially for small remote villages that have good access to biomass but no access to grid power, and which require only small scale power production. Biomass based power is also relevant in the context of climate change and global warming as biomass based power production is net carbon neutral. The contribution of bioenergy to the total primary energy consumption in India is over 27% (Source: FAO). This is indeed the case for many other countries, because biomass is used in a significant way in rural areas in many countries. However, the contribution of biomass to power production is much smaller than this percentage – currently, biomass comprises only about 2650 MW of installed capacity, out of a total of 172000 MW of total electricity installed capacity in the country. Besides, biomass power has the following benefits- distributed generation, baseload power, ability to have small, kW scale power production, suited for rural areas and ideal for rural economic upliftment. I believe these are enough to justify why biomass is best suited for power production. Check out: EAI Consulting for Bio-energy & Biofuels, Bioplastics & Other Biomass-based Value Added Products
