I want to do that but with a carbon anode. Cathode makes H2, anode makes CO2, very small electrical input to drive the reaction. If that can be figured out, then you can make H2 with charcoal. That's CO2 + 2H2, and if you use a traditional H2 electrolyzer to make another 50% of H2, then you can do CO2 + 3H2 -> CH3OH + H20, and that's methanol which is quite useful.
