What is Carbon Capture and Storage (CCS) and How Does it Work?

CCS could reduce the CO 2 emissions from a modern conventional power plant by 80-90%. Although power plants can benefit from carbon capture, most CCS projects are industrial, coming from industries such as cement or steel making and fertiliser production. Furthermore, CCS, when combined with biomass, can even result in net negative emissions.
