EV’s have been around since the dawn of ICE cars pretty much.

It’s unwise to say something is impossible, because people tend to find solutions, but AFAIK there is no known way to store Hydrogen efficiently.
Apart from that hydrogen production is very wasteful, meaning the complete system waste about 45%, before actually producing useful energy from fuel cells.
Seems to me this is not just an engineering problem, it’s a problem we simply don’t know if a solution even exist.
Fuel cells have been heavily researched for 30 years now, and it seems like they are getting nowhere. In the mean time Tesla was started “just” 20 years ago, and progress on batteries and EV is very strong.

Leaked hydrogen (H2) also binds to oxygen to create water vapor, which is a problem because GHG also binds to oxygen or OH and becomes neutralized. Some studies peg Hydrogen leakage at scale as being 100x worse, in the short term, than CO2 for warming due to this impact.

Thank you, very interesting article, I’ve always claimed Hydrogen isn’t a benefit, because it’s to wasteful so it may be actually detrimental over just using the original fuels used to make hydrogen directly. But I never even considered the hydrogen itself would be a problem. But reading the article, it’s actually quite obvious, that at scale it’s absolutely a problem that it “occupies” oxygen that is used to break down greenhouse gasses.
