You'll have to transport H2 too, not such a huge difference there.
Actually you'll need triple the volume for the same amount of energy but we're going off track - this scenario is far away.

Very true, and not to mention the energy efficiency of combustion engines themselves after everything else is said and done.

Not really - we all know the combustion engine doenst really have a future.
What we do need to focus on how to feed them - it's absolutely irrelvant how efficent an otto engine is.
Baseline: It's not an alternative yet, longterm maybe - all we know is we'll need a sh1tload of energy in the future and we have absolutely no clue where to get if from.
