There is an error in the blue box to the right of the diagram: it says green hydrogen will be require significant iridium. I think "be" should be "not". Thanks for the reports. Steve

For PEM Electrolyzer: Iridium is actually the primary PGM used in the PEM Electrolyzer technologies. Platinum is a secondary scale loadings. A number of papers on design thrifting on this topic are available including the following:

PEM Fuel Cells for transportation typically use only Platinum.

This Electrochemical Society technical paper outlines the loadings ranges.

And then on Iridium design thrifting look up

Thank you for your response to my confused comment. I had not been aware of the use of catalysts in electrolytic hydrogen production, and I took the threat to prices in the opposite sense. I should have read it better before writing. Steve
