Carbon capture and storage
Process of capturing and storing carbon dioxide from industrial flue gas
Carbon capture and storage
Carbon capture and storage (CCS) is a process by which carbon dioxide (CO2) from industrial installations or natural sources is separated before it is released into the atmosphere, then transported to a long-term storage location. The CO2 is captured from a large point source, such as a natural gas processing plant and is typically stored in a deep geological formation. Around 80% of the CO2 captured annually is used for enhanced oil recovery (EOR), a process by which CO2 is injected into partially depleted oil reservoirs in order to extract more oil and then is largely left underground. Since EOR utilizes the CO2 in addition to storing it, CCS is also known as carbon capture, utilization, and storage (CCUS). Oil and gas companies first used the processes involved in CCS in the mid‑20th century. Early CCS technologies were mainly used to purify natural gas and increase oil production. From the 1980s, and especially in the 2000s, CCS began to be discussed as a strategy to reduce greenhouse...
