Can hydrogen store as much energy as gasoline in the same volume?

[pa5tabear]

Calculating the internal energy of gasoline is fairly simple, because it wouldn't vary much with temperature or pressure.

For hydrogen, though, it would vary significantly with each. What sort of ranges would we be looking at?

I'm curious if it would be possible to get the same amount of energy from hydrogen as it would be from an equal volume of gasoline.
