Yes, exactly! Or any other hydrocarbon. This is a carbon-neutral process also, as the carbon will come from CO2 in the atmosphere. And we get the bonus of extra oxygen in the air...

Wouldn't the extra oxygen get burned up as you burn the fuel? It would be a carbon neutral and oxygen neutral process.

I think you're right, the oxygen would be sourced from water and water is also one major product of hydrocarbon combustion, which can be easy to forget.

Why would this be desirable?

Lowering the density of surface co2 could result in a reduction of the cognitive impairment caused by the already-increased co2 levels. It would also mean combustible fuels of all sorts would burn more efficiently.

/s, mostly
