Capture of CO 2 from medium-scale emission sources
Until now, the work done on capture and storage of CO2 has mainly focused on capture and storage of CO2 from fossil fuel fired power plants and other large point sources. Although medium-scale sources of CO2 account for a smaller proportion, their contribution to global CO2 emissions is still substantial and in the range of 10–15% of total global energy related CO2 emissions. The study identifies possible combinations of capture technologies and medium scale combustion installations and assesses these in terms of potential and costs. Although medium-scale capture of CO2 is expected to be more expensive than large-scale capture, it may nevertheless be competitive with alternative methods of abating CO2 from medium-scale sources in some circumstances.
