Hydrogen Is Working and It’s Much Cheaper Than We Thought

Half way right.

You can't compare gaseous hydrogen with a liquid fuel by volume. It has to be by weight.

Here's a hydogen advocate's takeo nit:

h2-- 60,000 btu per pound
gasoline 18,000 btu per pound

And here's a more neutral chart that claims the same:

Now, will a real chemist or physicist kindly explain why such a flimsy thing as hydrogen has such a high BTU level? Do all those carbon atoms in hydrocarbons mean little?

And, yes, I'm aware of the trade-off in the energy used to compress the hydrogen-- the point made by the first guy is that you can reduce compression costs.
