Oxygen really likes being connected carbon so spitting it off takes a lot of energy. All the things you mentioned burn in oxygen for exactly that reason. Making them requires at least as much energy as you’d get back by burning them so is hard to justify right now when instead you could make it directly from the carbon in things like fossil fuels and not have to spend all the energy to spit oxygen off first

- pgeorgi 3y agoI guess that's something humanity can consider once the question of energy sources is settled. For now, whatever energy that could be used to gather energy to split CO2 into C and O2 could as well be used to replace fossil-burning generators, at likely better efficiency.
