you want to bring moles into it? I haven't taken a chemistry course since High School.

Here's the thing-- if I got a tank of liquid hydrogen and a tank of gasoline, which will do more work? Since it's a lot of energy to liquify hydrogen, what density of the gas is the most efficient pressure to get the most work done? And how does that compare with, say, methane?

I have no argument with hydrogen, and have even played around with it a little (electrolysis is easy), but any discussion of it has to end up with practical uses and comparisons.

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