Schematic showing both terrestrial and geological sequestration of carbon dioxide emissions from a coal-fired plant Carbon capture and storage ( CCS) (or carbon capture and sequestration or carbon control and sequestration ) is the process of capturing waste (CO 2) from large, such as, transporting it to a storage site, and depositing it where it will not enter the atmosphere, normally an underground. Best Of Platinum Edition Dj Otzi Music. The aim is to prevent the release of large quantities of CO 2 into the atmosphere (from fossil fuel use in power generation and other industries). It is a potential means of the contribution of to and. Although CO 2 has been injected into geological formations for several decades for various purposes, including, the long term storage of CO 2 is a relatively new concept. The first commercial example was the in 2000.

Other examples include and. 'CCS' can also be used to describe the of CO 2 from ambient air as a technique. An integrated pilot-scale CCS power plant was to begin operating in September 2008 in the eastern German power plant run by utility, to test the technological feasibility and economic efficiency. CCS applied to a modern conventional power plant could reduce CO 2 emissions to the atmosphere by approximately 80–90% compared to a plant without CCS. The estimates that the economic potential of CCS could be between 10% and 55% of the total carbon mitigation effort until year 2100.

Carbon dioxide can be captured out of air or fossil fuel power plant using (or ), membrane gas separation, or adsorption technologies. Amines are the leading carbon scrubbing technology. Capturing and compressing CO 2 may increase the energy needs of a coal-fired CCS plant by 25–40%.

These and other system costs are estimated to increase the cost per watt energy produced by 21–91% for fossil fuel power plants. 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. Storage of the CO 2 is envisaged either in deep geological formations, or in the form of. Deep ocean storage is not currently considered feasible due to the associated effect of.

The (NETL) reported that North America has enough storage capacity for more than 900 years worth of carbon dioxide at current production rates.

A general problem is that long term predictions about submarine or underground storage security are very difficult and uncertain, and there is still the risk that CO 2 might leak into the atmosphere. Main articles:,,,,, and Capturing CO 2 is most effective at point sources, such as large fossil fuel or biomass energy facilities, industries with major CO 2 emissions,, synthetic fuel plants and fossil fuel-based plants. Extracting CO 2 from air is also possible, but not very practical because the CO 2 is not concentrated. Organisms that produce by generate cool, essentially pure CO 2 that can be pumped underground. Fermentation produces slightly less CO 2 than ethanol by weight. Flue gas from the combustion of coal in oxygen has a large concentration of CO2, about 10-15% CO 2 whereas natural gas power plant is about 5–10% CO 2. Therefore, it is more energy and cost efficient to capture CO2 from coal-fired power plants.
