When we burn fossil fuels, we emit carbon dioxide (CO2) into the air, one of the Green House Gases (GHG) that contributes the most to global warming.
Carbon Capture and Storage (CCS) refers to a new technology that enables us to capture the CO2 emitted by power plants and burry it deep under the ground, to a depth of at least 800 meters.
The captured CO2 is liquified and then transported by pipelines or by roads from a power plant to a storage plant.
There are three ways to capture and liquefy CO2 used worldwide: pre-combustion, post-combustion and oxyfuel methods.
It is stored and sequestrated in layers of the earth, such as deep saline aquifers or depleted oil or reservoirs.
