Well, a UK tablespoon comes close… (assuming the hydrogen is brought to “standard temperature and pressure.”)

However, the question is, “So what?” To produce that mole of hydrogen requires a great deal of energy; somewhat more than you will get back if you recombine it with 11 liters of oxygen to produce the original mole of water.

I believe hydrogen has great potential as a way to store energy, but I don’t see where this particular bit of trivia is meaningful.

Actually comparing hydrogen to octane by weight isn't valid either. TexasTowelie Aug 2016 #6
