Carbon Capture Storage (CCS)
What is Carbon Capture
Storage (CCS) ?
Carbon Capture Storage is a
technique for trapping carbon
dioxide as it is emitted from large
point sources, compressing it into
a liquid, and transporting it to a
suitable storage site where it is
injected into the ground
Stage 1 Capture - Involves separating CO2 from other gases in the exhaust stream. At power plants, separation technologies can be used to capture CO2 after combustion (post-combustion capture) or to decarbonise the fuel before combustion (pre-combustion capture).
Stage 2 Transport - Captured CO2 is transported to a suitable site for final storage located at a distance from the CO2 source - usually done by pipeline with CO2 compressed to a supercritical state (temperature and pressure at which it behaves as both liquid and gas).
Stage 3 Storage - Various options are possible for final storage of CO2. At present, injection into underground geological formations is the most promising and developed method.
Applying CCS to UK power generation (especially coal) was framed as a promising way forward in the 2003 Energy White Paper
The European Commission still have concerns that CO2 captured and stored remains isolated from the atmosphere in the long term. The Commission has proposed a regulatory framework and is examining ways to promote commercialisation of CCS through a network of demonstration plants
Norwegian company Statoil has been pumping CO2 into a sandstone layer under the North Sea for years
