Plug in hydrogen hybrid

[Mustang Dave]

The only problem with extraterrestrial hydrogen is that it would consume atmospheric oxygen. Permanently.

Lol, it is certainly not the ONLY problem, but you are correct that it would be a large problem, all the vehicles constantly binding oxygen to water, instead of co2 where the plants can do their thing with it. In fact you have just made me a bit concerned about all the c02 sequestration discussions...

I wouldn't worry about it, only a tiny fraction of C02 is going to be stored. Its not going to have any effect on anything, good or bad.
When we burn natural gas most of the waste is water vapor and we burn millions of tons of natural gas every year.
Water = good

Hard to compress, terrible energy density, net energy looser, highly flammable, explosive, hard to store.

There is more hydrogen in a gallon of gasoline, than there is in a gallon of hydrogen, as stored in any simple pressurized tank. Or even in cryogenic liquid hydrogen. Horrible energy density by volume.

And it either comes from natural gas (bad) or is (typically) made on site in the application you describe, by electrolysis of water. Best case scenario, under high pressure, with the good platinum electrodes, under carefully controlled conditions, 70-80% EROEI (Energy Returned On Energy Invested). Under the hood of a car, without the fancy schmancy equipment, you'd be doing very good to exceed 40%.

Hydrogen is a total dead end for automotive use.
