The catalysts for hydrogen->electricity are the same rare earths that people complain are harmful in EVs. Electricity->hydrogen->electricity is also far more lossy than the over 80% efficiency of the lithium cycle. Hydrogen has a round trip efficiency of 40%.
You may hear ‘it turns into water’ but that’s just obfuscating the origin of it (which may be electricity or more likely cracking fossil fuels).
All up I don’t see how you could claim it’s better than current electric cars from an environmental point of view.
