And that's the problem: hydrogen production is a huge waste of energy. Well to wheel efficiency of fuel cells is 22% vs 73% for battery EV (source: https://twitter.com/transenv/status/899976235794788352/photo/1 https://twitter.com/transenv/status/899976235794788352/photo...)

- darksaints 7y agoI can't speak to well to wheel, but at the very least current research tech electricity to hydrogen to electricity round trips are 75% efficient. https://www.nature.com/articles/s41560-019-0333-2 https://www.nature.com/articles/s41560-019-0333-2
