What is CO₂ Capture and geological Storage?

CO₂ capture and geological storage – often known by its acronym CCS and sometimes referred to as ‘carbon capture’, ‘carbon sequestration’ etc – is a process to capture carbon dioxide emitted from industrial and energy-related sources like the In Salah plant and power plants, chemical facilities and refineries, before it is vented into the atmosphere.

After capture, the CO₂ is then compressed and injected deep underground in secure geological formations. This injected CO₂ is then monitored very closely to assure that it stays underground permanently.

In Salah is demonstrating on a large scale that CO₂ capture and geological storage is safe, effective and can be done now. The geology at In Salah also represents the type of rock structure found in many parts of the world where there are major sources of CO₂ emissions, such as in Northern Europe, the United States and China.
