Total SA will capture and store 150,000tns of carbon dioxide in a depleted gas field in SW France in 2008-10 under a pilot trial to reduce greenhouse gas emissions. The USD 78 million initiative will involve a steam production unit at the Lacq gas processing plant. Oxygen will be used for combustion rather than air to obtain a more concentrated CO2 stream that will be easier to capture. Once purified, the CO2 will be compressed and delivered by pipeline to the depleted Rousse field, 30km from Lacq, where it will be injected through an existing well into a rock formation 4500m below. Total will work with Air Liquide, the French Petroleum Institute, the French Bureau of Geological and Mining Research, and others for this project.
