It actually gets it off with the oxygen, but you have the
right idea, that air-breathing H2-fueled engines are still
pretty dirty.

Yep. Not to mention that before the H2 can be used as fuel
it must be split from the oxygen in water (the usual
source), making the entire process a net energy loss.

Pesky entropy... ;-)
