Fusion Fuel Green, an Irish cleantech company founded in 2017, develops a micro PEM-based electrolyzer called the HEVO, which uses solar energy to create hydrogen with zero carbon emissions. Fusion Fuel Green produces hydrogen at highly competitive costs using renewable energy. The company aims to contribute to sustainable and affordable clean energy solutions.
Challenges: hydrogen fuel
The development of the global economy and the growth of population demand for more energy. Petroleum, coal, and natural gas are the primary sources of energy today. However, due to the non-renewability and limited reserves of fossil fuels, the rising energy demand results in energy crises, environmental pollution, and global warming. Hydrogen (H₂) is a “simple solution” to address the world's energy problems and needs.
Electrolysis of water is a mature technology for producing pure hydrogen. However, electrolyzers demand a large amount of electric energy. Today, an increasing number of electrolyzers use inexpensive solar cells that convert sunlight into electricity to produce hydrogen without emitting carbon dioxide (CO₂). The type of hydrogen is referred to as “green hydrogen”. Due to the dual limitations of solar cell conversion efficiency and electrolysis efficiency, as well as the poor matching of the maximum power points of the two, the solar cell hydrogen generation efficiency is relatively low. This hinders industrialization progress.
Fusion Fuel Green Technology
Fusion Fuel Green has developed a hydrogen generation device composed of micro PEM electrolyzers (HEVO) coupled directly with highly efficient, multiple-junction solar cells. The device collects and concentrates sunlight, converts concentrated sunlight into both electricity by the solar cell and thermal energy harvested by a heat exchanger. Thereby, the device utilizes the electric and thermal energy to produce green hydrogen at a cost-competitive price.
