H2U Technologies has demonstrated electrolyser stacks that replace scarce iridium catalysts with abundant materials and is on track to ship its first proof-of-concept systems next year.
H2U’s PEM electrolyser stacks leverage readily available catalyst materials to enable cost-effective green hydrogen generation.
The development of alternative catalysts is significant as highly constrained sources of costly platinum group metal (PGM) materials, such as iridium, a mainstay electrolyser catalyst, will lead to supply chain shortages and price increases.
The catalysts used in the new electrolyser stack are optimised with H2U’s CDE originally developed by Caltech. The data-driven CDE rapid-screening process allows scientists to make, characterise, and quantify the catalytic activity of thousands of material compositions per week – faster than any other screening process available.
