New Hydrogen Production Technology: Thermo-Photovoltaics, Create H2,O2 & Heat

Here’s an article posted in Oil Price.

According to the article,

  • A new type of solar cell technology has been developed that can create hydrogen, oxygen, and heat.
  • This technology uses a process called thermo-photovoltaics, which involves absorbing sunlight and converting it into heat, which is then used to split water into hydrogen and oxygen.
  • The hydrogen and oxygen can be used as clean energy sources, and the heat can be used for other purposes.

Additional details about the post:
Thermo-photovoltaics (TPV) is an emerging technology that converts heat into electricity via photons, which are then utilized to produce hydrogen peroxide (H2O2) and heat simultaneously. This innovative process offers a promising pathway for sustainable hydrogen production. Let’s break down the process along with some specific data points:

  1. Heat Generation: The process begins with the generation of heat from a heat source, which could be renewable or waste heat from industrial processes. This heat is typically in the range of 800°C to 1200°C.
  2. Photon Generation: The high-temperature heat source emits photons, which are then absorbed by a TPV device. TPV devices are designed to efficiently convert these photons into electricity using photovoltaic cells. These cells are often made of semiconductor materials such as gallium arsenide or silicon carbide.
  3. Electricity Generation: As the photons strike the photovoltaic cells, they create electron-hole pairs, generating electricity. The efficiency of this conversion process is a crucial factor. TPV systems can achieve efficiencies ranging from 20% to 50%, depending on the design and materials used.
  4. Hydrogen Peroxide Production: The electricity generated by the TPV system is then utilized in an electrolysis process to split water (H2O) molecules into hydrogen (H2) and oxygen (O2). However, instead of producing pure hydrogen gas, this process selectively yields hydrogen peroxide (H2O2) as a primary product.
  5. Chemical Reaction: The electrolysis of water to produce hydrogen peroxide involves a two-electron reduction of oxygen at the cathode. This reaction can be optimized to favor the production of hydrogen peroxide over hydrogen gas.
  6. Heat Recovery: Simultaneously with hydrogen peroxide production, the TPV system also generates heat as a byproduct. This heat can be captured and utilized for various industrial processes, enhancing the overall efficiency and sustainability of the system.
  • TPV systems can achieve electricity generation efficiencies ranging from 20% to 50%, depending on factors such as design, materials, and operating conditions.
  • The electrolysis process for hydrogen peroxide production typically requires a voltage of around 1.8 to 2.0 volts.
  • The selectivity of the electrolysis process can be tailored to produce hydrogen peroxide with yields exceeding 90%.
  • Hydrogen peroxide (H2O2) is a valuable chemical widely used in various industries, including water treatment, chemical synthesis, and electronics manufacturing.
  • The heat generated by TPV systems can reach temperatures of 800°C to 1200°C, suitable for a range of industrial applications.

Overall, thermo-photovoltaic technology offers a promising approach to sustainable hydrogen peroxide production, leveraging renewable heat sources and efficient photon-electricity conversion. This process holds significant potential for advancing clean energy and chemical production systems.
