Hydrogen doesn't exist randomly in a well or something it has to be created by using electricity - and that transformation is very inefficient if you then use the hydrogen in an inefficient way to power an engine instead of just using the electricity directly

That argument that energy is coal-heavy actually counts against hydrogen...

Hydrogen powered stuff only makes sense when electric isn't an option like for planes that just can't carry heavy batteries

Apparently, some hydrogen does come out of the ground like methane: https://www.weforum.org/agenda/2023/09/white-hydrogen-deposit-france/ but I assume it's not abundant enough to make a difference
