Why it's stuck
Iridium is one of the rarest elements and there is not enough to scale green hydrogen. A 2026 imaging study showed it degrades in ways researchers did not expect, so the models used to design replacements may be wrong.
What we'd try
Simulate the breakdown at the atomic level under real operating conditions, then screen low-iridium and iridium-free materials for stability.
What could stop us
Computational screening of low-iridium catalysts is crowded, and the source study already combined simulation with imaging, so only a narrow angle would add anything.
