AquaHydrex, a decade-old Colorado based electrolysis designer, claims to have figured out a more effective way of producing green hydrogen. Although not many details have been made public at this point, the new electrolysis process has been designed from the ground up, more closely resembling an Alkaline electrolysis design, trying to avoid the high capex cost often associate with PEM electrolyzers. PEM electrolysis has always been hindered by the high cost of its catalyst, usually made from platinum or iridium, and by its acidic environment. CEO Steve Kloos explained that PEM “puts too much dependence on the rarest metal in the Earth’s crust – Iridium, and relies on an overly sensitive membrane.” But as we said the design is from…
