Carbon dioxide storage in unmined and unmineable coal deposits is an original way to store carbon dioxide compare to the other geological storage options (which are deep saline aquifers, depleted oil and gas fields, basic and ultrabasic formations). Because coal is a heterogeneous and microporous sedimentary rock with a great specific surface (usually from 100 to 400 m2.g-1), anthropogenic carbon dioxide can be stored in coal seams mostly by adsorption. In nature, coal seams contain originally gases such as methane or carbon dioxide.
