And consider the explosive force stored in a 350-700 bar (your AI's
number) pressure vessel that becomes brittle enough to go "bang".
That's one hell of a bang, even without the hydrogen itself
explosively combusting as part of the pressure release.

For a 'motor fuel' it is difficult to replace the benefits of liquids
that do not need pressure vessels (beyond their own evaporation
pressure, which is usually quite mild).  We have an entire setup in
place for transporting, storing, and dispensing liquids (gas/diesel
pumps).

But, to avoid more 'carbon' in the air, the liquids have to be
synthesized somehow from carbon already in the air.  And that we don't
have on a scale large enough to be a source to replace our current
liquid fuels.

     The catalyst people ARE getting better with grabbing
   CO2 and turning it into various 'fuel' hydrocarbons
   again. If there's hope for "CO2 Capture" it's with
   these scientists.
    They don't even HAVE to "break even" - just kinda
   sorta CLOSE. That'd be significant - "good enough"
    Again, as for 'motor fuel', I suggest isopropanol,
   and it has a decent 'octane rating' - around 112.
