Carbon capture and storage

Summary
Carbon capture and storage (CCS) is a process in which a relatively pure stream of carbon dioxide (CO2) from industrial sources is separated, treated and transported to a long-term storage location. For example, the carbon dioxide stream that is to be captured can result from burning fossil fuels or biomass. Usually the CO2 is captured from large point sources, such as a chemical plant or biomass plant, and then stored in an underground geological formation. The aim is to reduce greenhouse gas emissions and thus mitigate climate change. CO2 can be captured directly from an industrial source, such as a cement kiln, using a variety of technologies; including adsorption, chemical looping, membrane gas separation or gas hydration. , about one thousandth of global CO2 emissions are captured by CCS, and most projects are for fossil gas processing. The technology generally has a success rate of between 50 and 68% of captured carbon, but
