In 1998, the IEA Greenhouse Gas R&D Programme (IEAGHG) assessed the global potential for CO 2 enhanced coal bed methane (CO 2 -ECBM) recovery and associated CO 2 storage based on data from the one successful pilot project at the time in the San Juan Basin in the USA. After 1998, subsequent CO 2 injection projects in coal seams were generally determined not to be successful. Nonetheless, these projects contributed to “lessons learned” that helped advise further research and demonstration (R&D) activities. IEAGHG recently reassessed the status of R&D in CO 2 -ECBM and CO 2 storage. In this assessment, the primary objectives were to: (1) assess the global status of coalbed methane (CBM) production and the potential effects on CO 2 storage; (2) review the current status of research into the enhanced gas recovery (EGR) and geological storage of CO 2 in coals; and (3) develop an updated assessment of the global potential for EGR and geological storage of CO 2 in coal formations. The paper summarizes the results of this work, along with other related activities. It reviews the results from more recent CO 2 - ECBM and CO 2 storage trials in the San Juan Basin in the USA, the results of other small-scale demonstration projects conducted by the U.S. Department of Energy's (DOE's) Regional Carbon Sequestration Partnerships (RCSP) Program, and reviews the status of an ongoing DOE-funded project conducted by CONSOL and Virginia Tech University in the USA, as well as for the Coal-Seq Conso...
