HYDROFULE is developing Solar to Hydrogen Electrolyzer with efficiency over 40%
Hydrofule Energy Inc. is a development stage company conducting Research & Development work to build an affordable Solar to Hydrogen Electrolyzer with an energy conversion efficiency of over 40% that will produce Green Hydrogen at a cost of $2.00 /kg.
For large scale deployment of Hydrogen the cost of Solar Hydrogen must be signficantly reduced. Numerous studies have shown that increasing the Solar to Hydrogen conversion efficiency is a significant step in reducing Hydrogen generation cost. The current conversion efficiencies demonstrated by water splitting electrolyzers range between 10-20%. There is tremendous room for improvement in Photovoltaic-Electrolysis system efficiency by minimizing the water splitting voltage and deploying high efficiency eletrocatalysts in the electrolyzer. Hybridization of semiconductor oxide photoelectrodes, such as TiO2, WO3, BiVO4, etc, with noble metals can provide enhancement of photo electrochemical performance. Modification of electrode architecture for durability and selection of materials with lower bandgap and appropriate band edge potential is crucial in improving the efficiency of the cell.
Green hydrogen will be an essential part of our future as it will be a crucial enabler of global transition to sustainable energy and net zero emissions. Green Hydrogen will help decarbonise sectors such as automobiles, aviation and shipping, where it will be used as sustainable fuel, as well as in manufacturing industries such as steel and chemicals. Up to one-third of the required solar and wind electricity would eventually be used for water electrolysis to produce hydrogen, thus increasing the cumulative electrolyzer capacity to about 3600 GW by 2050 from 300 MW today.
