“And to store enough of it to do useful things, it must be stored a high pressures.”
Some facts:
Hydrogen can be stored as a liquid.
Hydrogen can be stored as a metal hydride.
It can also be stored underground.
Liquid hydrogen is cryogenic, its boiling point is approximately 20 Kelvin. For reference, Kelvin scale is absolute; room temperature is around 295 K. LH2 is "stored" (I use the term loosely) in vacuum insulated dewars, and boils off at a rate of approximately 1% of the container's rated capacity per day. Your statement is technically true, but highly deceptive. Shame on you.
It can also be stored underground.
Lots of things can be stored underground. LH2 will still boil off at 1% per day ...
TG, you're trying to put lipstick on a pig. It's still a pig. Hydrogen is not an energy source, nor is it a particularly good energy transfer medium. It has some utility as rocket fuel, for reasons very specific (as in impulse) to rocketry and not applicable terrestrial locomotion.
Have a nice day.
Now you’re going to put cryogenics in cars? Really?
LOL
Have you ever been around real world mechanics? Do you have an engineering background at all?
