But this is perfect. A complete reversion of the reaction, without any additional interesting inputs or intermediate stages.
You can imagine a closed-cycle, isolated "battety" that discharges into sparkling water, and charges back into fuel and oxygen.
This is exactly the miracle solution that can turn CO₂ back into fuel, which can be burned again in existing ICEs and gas turbines, then turned into fuel again, powered by solar electricity.
Collecting and concentrating the CO₂ is going to be a task in itself, but things like power plants or steelmaking furnaces offer high-concentration, pre-heated CO₂.
