I’ve talked about the company HyperSolar a couple times in the past as a company dedicated to making direct solar to hydrogen systems. The photocatalyst the company has invented is immersed into water and then a light source is turned upon it, resulting in hydrogen production.
The Photocatalytic water splitting technique developed by HyperSolar is an efficient, low cost alternative to using platinum on electrodes. In fact, by happy accident, HyperSolar has discovered not only a low cost alternative to platinum but a material that will slow down corrosion of the electrode.
And, as luck would have it, this new material doesn’t have to be confined to the company’s solar-hydrogen water splitting device but can also be used as a replacement for platinum in fuel cells as well.
