The real question is - is charge cycle efficiency enough of a restrictive

leaking out of storage (and producing the stuff and compressing or
liquifying it are all monsterously lossy processes).

I went on a tour of Diamond a couple of weeks ago, and they were talking
about recent work to zap their small particles at some molecular
structures which Nottingham university is developing to store hydrogen.
My brain was at risk of starting to hurt, but it sounded convincing at
the time.

People have been talking about that for years. ISTR (but it was a long
time ago so I could be very, very wrong) reading of tests where bullets
were fired through hydrogen adsorption tanks, the kind that were
intended for motor vehicle use, to prove that they wouldn't explode.

I remember seeing film of just such a test on Tomorrow's World about 40
years ago. What they don't show is that you can do the same through a
petrol tank.
