A process like this could be a middle step. Yes, it’s methane as a byproduct, but we could then use the methane as well. And if we could use this as a fuel, then all of the drilling and mining for coal and gas goes away, lessening even more greenhouse gas pollution. In any event, this looks like a way that each nation could produce it’s own fuel from the air, meaning that we could let the coastlines of the world heal from the ravages of underwater oil drilling, and let Nigeria heal from the oil spills on its soil.
