Deep dive into our work


Electrolysis is a mature technology that uses electricity to split water into hydrogen and oxygen. It is considered one of the most promising methods for clean hydrogen production, especially when coupled with renewable energy sources like solar or wind power. Alkaline water electrolysis and proton exchange membrane (PEM) electrolysis are the most developed technologies in this category.

Thermochemical Water Splitting

Thermochemical water splitting uses heat and chemical reactions to produce hydrogen from water. The sulfur-iodine (S-I) cycle and copper-chlorine (Cu-Cl) cycle are two of the most promising thermochemical cycles under development. These cycles can achieve high efficiencies and use nuclear or concentrated solar power as the heat source.

Photoelectrochemical Water Splitting

Photoelectrochemical water splitting uses light-absorbing semiconductors to directly split water into hydrogen and oxygen. This method has the potential for high efficiency and low cost, but it is still in the research and development stage. Improving the performance and stability of photoelectrodes is a key focus area for this technology.

Biomass Gasification and Pyrolysis

Gasification and pyrolysis of biomass and waste materials can produce hydrogen-rich syngas that can be further purified to obtain hydrogen. These thermochemical processes are considered promising due to their potential for low cost and the ability to use a wide range of feedstocks. Supercritical water gasification (SCWG) of biomass is particularly promising as it can handle highly moisturized feedstocks without the need for drying.

Biological Hydrogen Production

Biological methods like dark fermentation and photo-fermentation use microorganisms to produce hydrogen from organic matter. These methods are still in the research and development stage but have the potential for low cost and the ability to use waste materials as feedstocks. Improving hydrogen yields and process efficiencies are key challenges for these technologies. While each of these methods has its own advantages and challenges, the combination of electrolysis powered by renewable energy and thermochemical water splitting using nuclear or solar heat appears to be the most promising path forward for large-scale, cost-effective, and clean hydrogen production in the near to medium term.
