Since the beginning of the Industrial Revolution in 1750, human activities have produced a 40% increase concentration of carbon dioxide in the atmosphere, from 280 ppm in 1750 to 406 ppm in early 2017. U.S. energy‐related carbon dioxide (CO2) emissions totaled 2.53 billion metric tons in the first six months of 2016. The main human activity that emits CO2 is the combustion of fossil fuels (coal, natural gas, and oil) for energy and transportation, although certain industrial processes and land‐use changes also emit CO2. CO2 sequestration is one of the effective ways to decrease CO2 emissions to reduce the effect of global warming. Geologic sequestration is permanently storing CO2 in subsurface structures such as oil reservoirs, natural gas deposits, deep saline formations, and unmineable coal seams. CO2 sequestration in coal seams combines CO2 storage with enhancing methane recovery.

This chapter investigates the ability of CO2 sequestration in coal formations, and the effect of different parameters on the process behavior. It presents experimental results for adsorption isotherm, wettability behavior, and injectivity ...
