Could this be used to consume stranded methane that is now flared off at many oil wells?
The carbon electrodes are used to refine the aluminum in the first place. A careful reading of the article also indicates that the aluminum is turned into aluminum oxide. This also requires the same refining step to turn the aluminum oxide back into aluminum. My point was that they were ignoring the fact that creating aluminum requires a lot of energy and has its own CO2 problem. Nice lab experiment but if you are looking for a green solution this only solves a tiny part of the problem.
Nice science experiment. They don't talk about the electrical energy required recycle the aluminum oxide, or the CO and CO2 generated when the by the carbon electrodes consumed in the process. They also don't talk about round trip efficacy.
