Yeah I briefly looked into it; and the running gig now is “gassing up” with continually refreshed electrolyte solution - until eventually the aluminum anode is dead and must be replaced. Which is as you mentioned the standard aluminum smelting process 😂

So while that does put a pretty strict cap on systemic thermodynamic efficiency, overall it looks competitive with lithium-ion systems. The big downside I can foresee is that we can’t really expect to have nice things until our demographic situation improves.

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.
