Implied coal consumption in many of the reviewed CCS deployment
scenarios exceed projected coal production levels in many resource
constrained studies. This indicates that large scale CCS deployment can
be challenging if high efficient capture technologies are not commercialized
or if world coal production, and associated coal reserves, is not
significantly increased. Even if resource size were not to be a constraining
factor in the foreseeable future, increased coal consumption
still brings about a challenge for CCS deployment since it requires
additional coal mining compared to an all else being equal, non-CCS
scenario. Coal mining is associated with several environmental issues
and can be seen one of the most negative aspects of coal power besides
