Abstract
Subsurface coal seams are generally considered as important potential geological media for underground storage of carbon dioxide, but this is a more complex option than other storage options. The required number of wells and the uncertainties due to the complexity were generally considered as main barriers and large-scale projects are hence pending after the initial pilot projects. However, CBM production is currently initiated in coal basins throughout the world, thereby providing more and more possibilities for application of storage of CO2 in coal in the future. Experience gained from other CCS projects will be essential In this paper, it is recommended that - if feasible - future coal storage projects should be developed with horizontal injection wells in a mature CBM field that has seen peak production of CBM. The possibility of using horizontal wells for injection in coal should be tested first. An integrated approach aiming at local benefits through small-scale electricity generation or re-use of production water could have an clear added value. © 2011 Published by Elsevier Ltd.
