> The 33kWh per kilo of hydrogen

That's just a physical material property of hydrogen itself. It has nothing at all to do with anything else. 1kg of hydrogen has a (lower, not upper) calorific value of about 33 kWh, period. Doesn't matter where it's going, how it was made, what infrastructure was used, what any of the efficiencies involved were, ... You could magically conjure up 1kg of hydrogen from outer space and it would have that property too.

Pretty relevant what kind of practical efficiency you'd get converting it to useful work.
