That's one hell of a bang, even without the hydrogen itself
explosively combusting as part of the pressure release.
I've seen the results of a 200-bar scuba tank letting go. And
that's just a little 80-cubic foot tank filled with air.
I've seen that too - close up. Blew out a reinforced CBC wall
...... sheer dumb luck nobody was in the filling room at the time
or they'd have been Spam.

Hydrogen CAN have its uses - but at "industrial" sites, not out in
public. You can feed it into expensive fuel cells, you can mix
x-percent with natural gas.

But as a general-purpose 'motor fuel' ... NO ! Besides, no proper
infrastructure for it.
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.
