It is just a battery, and not a very good one. The energy efficiency is only 20% - meaning you have to use 4 times the energy to run the reaction and convert the CO2 as you will get from burning the ethanol. And of course burning the ethanol releases the CO2. If you want to sequestor carbon I don't think this is a promising route to take.

Great, thank you! this would help put a dent in climate change AND land use complaints surrounding ethanol :)
