Usually the CO 2 is captured from large point sources, such as a chemical plant or biomass plant, and then stored in an underground geological formation. : 2221 For example, the carbon dioxide stream that is to be captured can result from burning fossil fuels or biomass. Ĭarbon capture and storage (CCS) is a process in which a relatively pure stream of carbon dioxide (CO 2) from industrial sources is separated, treated and transported to a long-term storage location.
More than 75% of proposed gas processing projects have been implemented, with corresponding figures for other industrial projects and power plant projects being about 60% and 10%, respectively.
