The capture and storage of CO2

To reduce greenhouse gases emissions

The use of fossil resources produces large quantities of greenhouse gases. Capturing and storing CO2 is an alternative solution to releasing it into the environment, and Air Liquide is actively contributing to the development of such facilities.


Fossil fuels (oil, natural gas and coal), which currently account for over 80% of the world’s energy consumption, release CO2, or carbon dioxide, when they are burned. Failure to change energy production and consumption methods could result in a 60% increase in CO2 emissions between 2005 and 2030.

CO2, a greenhouse gas, is currently one of the main culprits of global warming. In order to limit the increase in temperature of the Earth’s surface to 2°C these emissions must be halved, meaning that we have to find ways of reducing them. Air Liquide is actively contributing to the development of such solutions, including the capture and storage of carbon (CCS), a promising solution which consists of capturing, transporting and storing industrial CO2 emissions in geological layers, thus recreating what nature has been doing for millions of years with its natural CO2 deposits.

Air Liquide is developing CO2 capture and storage technologies as an alternative to releasing such emissions into the atmosphere. The Group has recognized know-how and highly specialized expertise in this field thanks to the innovation and technological progress it that it demonstrates.

Air Liquide is already involved in many demonstration programs in pilot sites in France, the United States and Australia.
