Carbon capture and storage (CCS)

A set of technologies that can greatly reduce carbon dioxide emissions from new and existing coal- and gas-fired power plants, industrial processes, and other stationary sources of carbon dioxide. It is a three-step process that includes capture of carbon dioxide from power plants or industrial sources; transport of the captured and compressed carbon dioxide (usually in pipelines); and underground injection and geologic sequestration, or permanent storage, of that carbon dioxide in rock formations that contain tiny openings or pores that trap and hold the carbon dioxide. It can also refer to biological sequestration, which involves conservation practices that enhance the storage of carbon (e.g., restoring forests). Also known as Carbon Capture and Sequestration.
