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.
