This chapter explains CO2 sequestration and CH4 extraction potential of unmineable coal seams. The coal seams of Barakar formation of Singrauli coalfield in India was considered for this study. This sequestration process has dual benefits offers a promising approach to mitigating greenhouse gas emissions in the meantime improving natural gas recovery through coal bed methane (CBM) exploration. The studied coal seams show significant storage capacities, and estimated maximum sorption values are 10,758 Mm3 for CO2 and 3215 Mm3 for CH4. The results highlight the feasibility of utilizing unmineable coal seams for carbon sequestration and methane extraction which can contribute to both climate change mitigation and energy development.

摘要

This chapter explains CO2 sequestration and CH4 extraction potential of unmineable coal seams. The coal seams of Barakar formation of Singrauli coalfield in India was considered for this study. This sequestration process has dual benefits offers a promising approach to mitigating greenhouse gas emissions in the meantime improving natural gas recovery through coal bed methane (CBM) exploration. The studied coal seams show significant storage capacities, and estimated maximum sorption values are 10,758 Mm3 for CO2 and 3215 Mm3 for CH4. The results highlight the feasibility of utilizing unmineable coal seams for carbon sequestration and methane extraction which can contribute to both climate change mitigation and energy development.
