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

You don't have to use electricity to make hydrogen! You can make it from methane! But yeah, it's probably even worse than a diesel engine when it comes to CO2 emissions...

While it technically doesn't you "need" electricity, Methane Pyrolysis requires energy of some sort.
