HyperSolar, the developer of a breakthrough technology to produce renewable hydrogen using sunlight and any source of water, has announced it has achieved an important milestone in the project.
The company has announced that it had reached 1.25 volts (V), an important milestone achievement in its effort to split water molecules for the production of renewable hydrogen fuel.
HyperSolar’s research is centred on developing a low-cost and submersible hydrogen production particle that can split water molecules under the sun, emulating the core functions of photosynthesis. Each particle is a complete hydrogen generator that contains a novel high voltage solar cell bonded to chemical catalysts by a proprietary encapsulation coating..
The theoretical minimum voltage needed to split water molecules into hydrogen and oxygen is 1.23 V. However, in real world systems, 1.5 V or more is generally needed because of the low reaction kinetics. So far, other researchers have only been able to achieve this voltage level through the use of either inefficient materials, such as titanium oxide, or very expensive semiconductors, such as gallium arsenide. Also, overcoming the corrosive degradation of these “artificial photosynthesis” systems remains a monumental challenge and has thus far eluded commercialisation.
