CO2 is considered as one of the main causes of climate change. Two thirds of CO2 emissions come from fossil fuels used for power generation or from industrial processes as oil refineries, cement works, iron and steel production... The process of Carbon Capture & Storage could reduce substantially these CO2 emissions in the atmosphere.

Geological storage processes are under development in depleted Oil & Gas fields. Other geological options are studied in unminable coal seams or in deep saline aquifers. CO2 could also be stored into the deep ocean, but further research programmes are required to provide a better understanding of this technique.

Next steps for the development of CCS are cost reduction and acceptability improvement as a safe, reliable and long term containment of CO2. Since CO2 has been naturally stored for geological time-scales and many of the considered reservoirs have already stored gases and liquids for thousands of years, CCS appears to have a promising and bright future.
