What is Carbon Capture and Storage (CCS)?

What is carbon capture and storage?

Carbon dioxide (CO2) is a greenhouse gas that comes from burning fossil fuels, such as coal, oil and natural gas, through activities like driving a car or creating electricity. For large stationary sources of CO2, like an oil refinery, use of a carbon capture and storage can help prevent these emissions from entering the atmosphere by capturing CO2 from large industrial sources and injecting it into carefully selected sites deep underground for safe, long-term storage.

How does carbon capture and storage work?

CO2 is separated and collected from emissions produced by industrial activity, then compressed and transported to a storage site and injected into carefully selected, secure underground geological formations that can safely and permanently store the gas. After injection activity ends at the site, the site is tightly sealed and monitored to ensure there are no safety or health risks to the public or to the environment.
