Carbon capture and storage (CCS) is a technique to remove atmospheric CO2 (to avoid the release of CO2 to the atmosphere). The chemical process of CCS is energy demanding and probably in some cases CO2 can be released (such as in leakages). This process only causes a delay in the CO2 released since it cannot be stored for ever. However, this CO2 could be used in a vast range of ways. Carbon capture and storage (CCS) allow the capture of CO2 from fuel combustion or industrial processes, the transport and its storage underground, in geological reservoirs.
CCS is a GHG emission reduction technology, whose deployment is dependent on an enabling policy framework. CCS has been carried out in industrial scale and it has resulted in 1Mt CO2 stored per year. CCS contributes one-sixth of total CO2 emission reductions required in 2050.
CCS techniques carried out in a conventional power plant could reduce CO2 emissions in roughly 80-90% compared to a conventional power plant.
CCS techniques include reforestation (and afforestation) and geological storage.
