the hilarious thing is that, if it wasn't for the push for EVs, this could have easily caught on. the supply chain was a bit more complicated than gasoline given that hydrogen has to be compressed, but the stability and energy density of hydrogen is very similar to gasoline.
Yep, volumetric energy density of compressed gaseous hydrogen is laughable. Even cryogenic liquid hydrogen is not great and then you have all the crazy overhead of cryogenic storage.

Per unit mass, sure. Per unit volume, no, not at all, and it's not even close.
