Since 2003 Air Liquide has been working on a pioneering project to reduce CO2 emissions. Within the context of current concerns to reduce co2 emissions, Air Liquide has developed a high level of expertise in the field of co2 sequestration.

The industrial gas giant, already a partner in several research projects in CO2 sequestration, is extending its cooperation to the Midwest Geological Sequestration Consortium (MGSC) in a project sponsored by both the US Department of Energy and the Illinois Office of Coal Development. The project is being led by the Illinois state Geological survey (ISGS).

A new phase in this sequestration project has begun consisting of six real scale CO2 injection tests which will last until 2009. In this project Air Liquide will supply 19,000 tons of liquid CO2 to be injected during these tests as well as storage tanks for the CO2.

Promising avenue for reducing emissions
As well as energy saving and increasing use of renewable energy, capture and sequestration of CO2 emissions from fossil energy is a promising avenue for reducing existing emissions. This process consists of capturing industrial CO2 emissions and burying them deep in the underground layers of the earth. Although this process has already been carried out in several places, it still requires a certain number of tests. The tests are to prove its technical feasibility, its cost effectiveness and the sustainability of underground storage.

Dr Robert Finley, project director for MGSC stated; \\$quot;Since the start of the project, Air Liquide has provided its high-level scientific and technological expertise, and had assisted us in our search for environmentally friendly solutions to reduce greenhouse gases through geological sequestration.\\$quot;

Francois Darchis, member of Air Liquide\\$quot;s executive committee commented; \\$quot;This partnership illustrates our ability to implement the entire CO2 sequestration chain, by developing the technologies to concentrate, separate, transport and inject CO2 into the deep layers of the earth in order to trap it definitively. Today, Air Liquide spends over 50 per cent of its R&D budget on projects devoted to sustainable development. Thus, the group is developing the technologies of tomorrow and offering its customers more environmentally friendly solutions.\\$quot;
