Subsurface geothermal energy storage has greater potential than other strategies in terms of capacity scale and time duration. Carbon dioxide (CO2) is regarded as a medium for due to its superior thermal properties. Moreover, the use CO2 plumes mitigates greenhouse effect by storing geological bodies.

Summary Injecting CO2 into reservoirs for storage and enhanced oil recovery (EOR) is a practical cost-effective strategy reducing carbon emissions. Commonly, CO2-rich industrial waste gas used as the source, whereas contaminants such H2S may severely impact EOR via competitive adsorption. Hence, adsorption behavior of CH4, CO2, in calcite (CaCO3) micropores on sequestration methane are specifically investigated. The Grand Canonical Monte Carlo (GCMC) simulations were applied to study...
