The Coal-Seq II Consortium: Advancing the Science of CO2 Sequestration in Deep, Unmineable Coal Seams
Project # 40924
Primary Performing Organization:
Advanced Resources International
This project advances the economics of carbon dioxide (CO2) storage by contributing to scientific knowledge about the value-added benefits of enhanced coal bed methane recovery (ECBM). ECBM is deemed “value added” because (1) the large surface area of coal provides proportionately greater CO2 storage capacity in coal beds; and (2) the methane displaced by CO2 equates to natural gas and can be recovered and sold to offset costs.
In the first phase of Coal-Seq project, existing long-term multi-well ECBM projects were evaluated for the viability of storing CO2 in deep coal seams. A lot was learned about sub-surface reservoir behavior, leading to the ability to better predict performance of integrated ECBM/sequestration projects. See map of Tiffany and Allison units.

In the interest of gaining a better understanding of the CO2-sequestration/ECBM process, the project now is conducting experimental and theoretical R&D on coal reservoir behavior, and validating findings from the Phase 1 results. This should lead to a comprehension of the best geologic/reservoir environments and development strategies, and provide a single source on global activities on CO2 sequestration in deep, unmineable coals. Success will contribute to the construction of more ECBM projects, coupled with CO2 storage cost savings.
