First-of-a-Kind Field Test for Enhanced Coalbed Methane Recovery with Simultaneous CO2 Sequestration

Green Car Congress

Injection of CO 2 began in a first-of-a-kind US Department of Energy–sponsored field trial of enhanced coalbed methane recovery with simultaneous CO2 sequestration in an unmineable coal seam. These wells have been producing coalbed methane and water since 2004. When CO 2 is stored in a coal seam, the coal can swell.
