China may dominate H2 as well, but mining and refining mining materials is difficult/expensive. H2 does require membrane manufacturing (which US pioneered), but platinum group metals make the best catalysts. Innovation in other materials/approaches are progressed, but then these innovations delay electrolysis deployments as they don’t yet have the same capacity levels.
Isn’t H2 a dead end storage technology?
I thought the only people still doing it were Japanese automakers on account of the sunk costs fallacy.
