> the best engineering solution to the remainder of the task list of transport, store, and burn the resulting carbon-free hydrogen, is to modify the hydrogen by synthesize up some carbon containing hydrocarbons

If that's the case, it's equally true for H2 from renewables, no?

And I don't think it's true. LPG vehicles today are common enough, and they've solved very similar transport and distribution problems.

Not really. Hydrocarbons are much easier to store and handle. Cars may not need it so much, but as a jet fuel, kerosene is much easier than hydrogen.

Easier, sure. But Tupolev built and flew 100 flights with the Tu-155, a cryogenic H2 fueled narrow-body airliner, in the 1980s. So it's very far from impossible, it's just a matter of time IMO. Currently aviation is pushing biofuels to kick the can down the road, but they can't do that forever.
