Three questions about the storage of CO2 in oil wells, which France will experiment with to fight global warming

Storing CO2 in oil fields in France. This is the idea supported by the Minister of Industry and Energy, Roland Lescure, who launched a plan on Friday April 26 to experiment “four to five CO2 storage projects” in France from 2025. This announcement aims to help the largest French industries, which are very polluting, to meet their decarbonization objectives, while the country wants to halve the CO2 emissions of its industry by 2030. Franceinfo makes update on this announcement.
France, which has old or still active hydrocarbon reserves (oil and gas), intends to use these deposits – mainly located in New Aquitaine and the Paris region – to decarbonize its industry. These wells will be used to store CO2 emitted by industries. Roland Lescure launched a “call for expressions of interest”particularly aimed at players in the hydrocarbon sector.
Concretely, the government wants to capture the CO2 emitted by the most polluting factories (ffertilizer manufacturers, cement manufacturers, chemists, etc.), transport it then store it in the ground, several hundred meters deep. This CO2 capture and storage technology – there are other techniques, including capturing CO2 in the air – aims to trap the greenhouse gas produced by the combustion of fossil resources before it escapes into the atmosphere. And thus fight against global warming caused by human activities.
“The process consists of capturing the CO2 which escapes in the form of smoke at the exit of the factory, compressing it from a gaseous state to a quasi-liquid state and transporting it in pipelines in order to store it beyond 800 meters depth”summarizes for franceinfo Pascale Bénézeth, CNRS research director at the Environmental Geosciences laboratory in Toulouse.
