摘要
A novel idea involving the coupling of CO2 geological storage with methane and/or heat production (geothermal energy) from geopressured-geothermal aquifers is described herein. The production of energy from the extracted brine offsets the cost of capture, pressurization, and injection and the subsequent injection of brine containing carbon dioxide back into the aquifer. Calculations described in the present invention indicate that this offset would reduce the cost of carbon capture and sequestration (CCS) to a point that CCS could survive in a competitive market environment without subsidies or a price on carbon.
