Coal bed methane decarbonization via CO2 capture and storage and blue methane production

Lorraine underground contains deep coal seams that cannot be mined for regulatory and economic reasons. These coal seams contain methane but are also part of a sedimentary basin (Lorraine basin) able to store millions of CO2 tons. To compensate all CO2 emissions related to methane recovery in the deep coal seams, including transport and usages, a Life Cycle Analysis (LCA) is performed to evaluate the CO2 to be captured and stored locally with the objective of reaching decarbonized methane. The CO2 capture process used in this setup is the Cryo Pur CO2 capture process, using only electricity; its related CO2 emissions are included in the Life Cycle Analysis. Decarbonized methane is a fuel of great interest to produce low carbon blue Hydrogen. An analysis is done in terms of energy efficiency and carbon balance for the production of decarbonized methane and blue hydrogen.
