Carbon dioxide capture and storage (CCS) is an important concept to reduce greenhouse gas emissions, in particular from power plants. After CO2- capture the CO2 needs to be compressed to achieve the right transport and storage conditions. CO2 capture processes can be divided into three main categories: - postcombustion processes; - precombustion processes; - oxy-combustion/denitrogenation processes. These process categories are applicable to both fossil fuel and biomass. Several different physicalchemical gas separation methods used CO2-capture will be described. The capture of CO2 is the most expensive step in the CCS-chain. A systematic approach to costs and emission of the chain capture-transport-sequestration of CO2 is presented, for different power generation technologies, capture and transport technologies. This involves eight steps, incorporating the complete chain from fossil fuel extraction to the production of the energy carrier and the storage of CO2.
