CO2 sequestration in anthracite coal seams is also attractive due to the high CO2 holding capacity per unit volume/mass. For both anthraciteCBM and CO2enhanced CBM, the permeability of coal is one of the key decisionmaking parameters and thus a sound knowledge of the permeability evolution for anthracites will be essential.
At the same time, in some areas, decreasing coal quality and the use of highermoisturecontaining fuels such as Powder River Basin coal contributed to a reduction in unit performance.
