Carbon capture and storage (CCS) (or carbon capture and sequestration or carbon control and sequestration[1]) is the process of capturing waste carbon dioxide (CO2) from large point sources, such as fossil fuel power plants, transporting it to a storage site, and depositing it where it will not enter the atmosphere, normally an underground geological formation. The aim is to prevent the release of large quantities of CO2 into the atmosphere (from fossil fuel use in power generation and other industries). It is a potential means of mitigating the contribution of fossil fuel emissions to global warming[2] and ocean acidification.[3] Although CO2 has been injected into geological formations for several decades for various purposes, including enhanced oil recovery, the long term storage of CO2 is a relatively new concept. The first commercial example was the Weyburn-Midale Carbon Dioxide Project in 2000.[4] Another example is SaskPower's Boundary Dam. 'CCS' can also be used to describe the scrubbing of CO2 from ambient air as a climate engineering technique.
An integrated pilot-scale CCS power plant was to begin operating in September 2008 in the eastern German power plant Schwarze Pumpe run by utility Vattenfall, to test the technological feasibility and economic efficiency. CCS applied to a modern conventional power plant could reduce CO2 emissions to the atmosphere by approximately 80–90% compared to a plant without CCS.[5] The IPCC estimates that the economic potential of CCS could be between 10% and 55% of the total carbon mitigation effort until year 2100.[5]
Carbon dioxide can be captured out of air or fossil fuel power plant flue gas using adsorption (or carbon scrubbing), membrane gas separation, or adsorption technologies. Amines are the leading carbon scrubbing technology. Capturing and compressing CO2 may increase the energy needs of a coal-fired CCS plant by 25–40%.[5] These and other system costs are estimated to increase the cost per watt-hour energy produced by 21–91% for fossil fuel power plants.[5] Applying the technology to existing plants would be more expensive, especially if they are far from a sequestration site. A 2005 industry report suggests that with successful research, development and deployment (RD&D), sequestered coal-based electricity generation in 2025 may cost less than unsequestered coal-based electricity generation today
