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.
