*gack!* the gas in a water torch is Wood's gas (a hydrogen-oxygen
mixture) and it's explosive. You don't want to compress THAT.
As for hydrogen, it can be liquefied or compressed into intercalation
compounds (sponge-like material) for storage. The main problem
is, both are slow processes because the generated heat has
to be removed somehow (no hydrogen fillup in minutes at
your auto filling station). Hydrogen also embrittles metals,
and diffuses, it's NOT a well-behaved gas. Neither is oxygen, come
to that.
