I think this is called "green hydrogen" [1] which has application as an energy storage medium, but also more. Energy storage also does not imply, that that hydrogen needs to be turned back into grid electricity, but could be used for heating or for hydrogen cars.

I'm aware of the term, 'green hydrogen', which is in contrast to 'blue hydrogen' (or as I prefer to call it 'dirty hydrogen') which is a product of methane gas extraction and allows some of that methane to escape.

I'm under the impression that hydrogen ICE vehicles at scale is impractical due to lack of infrastructure, safety issues etc, at least compared to batteries

Methane synthesis is a potential solution. Simpler infrastructure/reuse of existing infrastructure.

Or potentially methanol (and better yet, butanol, which is easier to deal with than methanol, less corrosive, less hydroscopic).
