What is CCS?
Carbon Capture and Storage is a technique for trapping carbon dioxide as it is emitted, compressing it, and transporting it to a suitable storage site where it is injected into geological formations including oil and gas reservoirs, unmineable coal seams, and deep saline reservoirs.
CCS is not a new technology. CO2 has been captured for nearly 100 years for industrial purposes or to increase oil or gas production. When not captured, CO2 is vented into the atmosphere; the costs of capture and storage are high and regulatory frameworks, incentive frameworks and support programs do not yet exist.
Capturing and storing CO2 as a technology to mitigate climate change is new. Demonstrating the world that the CCS chain works and forms an essential part in the process of CO2 reduction, and scale down the costs represent a huge challenge.
