Where the coal bed is suitable the CO2 can be injected into the coal bed, where it will be absorbed.

A by-product of this method would be the production of methane, which can be sold thereby offsetting the cost of disposal of CO2.

Research is being undertaken into: the permeability of the coal, understanding the process of CO2 absorption and a field experiment in Poland.

There is the possibility of injecting non-pure CO2 into the coal bed, thereby reducing the cost of capture; work on this was being carried out in Canada. However the economics is not yet known.
