ABSTRACT:
A method for generating oxygen-depleted air for injection into a subterranean coal seam for increasing production of methane. Air and produced fluids comprising methane are input into a fuel cell power system; and fuel cell power system exhaust comprising oxygen-depleted air is injected into the coal seam.
