Hydrogen might have a niche where weight vs energy density of batteries doesn't work and hydrogen just makes more sense but yeah the fact that there's a couple of more steps along the chain makes hydrogen less efficient than batteries.
If we had fusion reactors and could generate nearly unlimited free electricity like Fuzz says then it might make sense but the physics challenges are tough.
Park your hydrogen car and a week later all the hydrogen has boiled away.
