In 2005, environmental services company Veolia began a research programme on carbon capture and storage, to explore capture techniques for its clients’ medium-scale facilities, such as thermal power stations, municipal waste incinerators and landfill gas burning sites.

The company selected a site at Claye Souilly, near Paris, for an industrial-scale pilot unit to capture and store CO2 at an annual rate of 200,000 metric tonnes. The programme, expected to be the biggest of its kind in France, would capture CO2 from a landfill biogas-to-energy facility at the site and store it within a saline aquifer at a depth of more than 1,500 metres.

The selection of the Claye Souilly site in 2008 kickstarted geological studies at Claye Souilly in partnership with Geogreen, an international joint venture between IFP, BRGM and Geostock.

In December 2009, Veolia announced start-up of its landfill gas-to-biomethane fuel facility at Claye Souilly, where the demonstration unit began testing two technologies for separating CO2 from the biogas - the VPSA process, which adsorbs components on porous solids, and a membrane process. The technology ultimately chosen will be used at other non-hazardous waste landfill sites.

Transport and storage of CO2 has begun on a research level. A joint report for the CO2 storage site investigations was published for the GHGT11 in 2013.


Veolia has invested €1.6 million in the Claye Souilly landfill gas-to-energy pilot, for which it received a subsidy of €300,000 from ADEME, France's environment and energy management agency.
