Abstract: potential to sequester CO2 while simultaneously enhancing coalbed methane (CO2-ECBMPilot tests of CO2-ECBM have been conducted in coal seams worldwide with favorable early resultsgas—a mixture of mainly N2 and CO2—is an attractive alternative for ECBMThese results suggest that flue-gas ECBM for deep coal seams may provide a promising path toward net-zero
