CO2 can be captured using a liquid solvent or other separation methods. In an absorption-based approach, once absorbed by the solvent, the CO2 is released by heating to form a high purity CO2 stream. This technology is widely used to capture CO2 for use in the food and beverage industry.
How is CO2 captured and stored?
Where can captured carbon dioxide be stored? After capture, carbon dioxide (CO2) is compressed and then transported to a site where it is injected underground for permanent storage (also known as "sequestration"). CO2 is commonly transported by pipeline, but it can also be transported by train, truck, or ship.Jan 6, 2017
Where the captured CO2 can be stored?
The three main types of geological storage are oil and gas reservoirs, deep saline formations, and un-minable coal beds. CO2 can for instance be physically trapped under a well-sealed rock layer or in the pore spaces within the rock.
