- CO2 storage, a limited solution to achieve carbon neutrality by 2050.
- Three regions of France could be concerned according to Ademe.
- These are Hauts-de-France, Normandy and New Aquitaine.
Store pollution if not avoid it. France has set itself the ambitious objective of achieving carbon neutrality by 2050. While it is indeed planned to work on reducing CO2 emissions in the production processes of certain industries, others, among the most polluting, will have to turn to the “essential” storage solution. The Environment and Energy Management Agency (Ademe) has therefore issued an opinion for the implementation of this solution, subject to conditions, in "three specific areas of French territory": Normandy, Hauts -de-France and Nouvelle-Aquitaine.
Geological carbon capture and storage (CCS) is a technology used to recover CO2 from factory fumes before transporting it to store it underground and thus prevent its emission into the atmosphere. It is an expensive solution which also requires many years of development to be completed. High “technical, geological, economic, regulatory and societal” constraints which, according to Ademe, only allow implementation in Hauts-de-France (around Dunkirk), in Normandy (Le Havre and Rouen) and in New Aquitaine (Lacq).
100 to 150 euros, the cost of a tonne captured and stored
In fact, in these sectors are grouped industries that emit a lot of carbon whose production processes cannot be profoundly modified to decarbonize their activities. These areas also have the advantage of being near potential storage sites, mainly located at sea. Two criteria which, according to Ademe, make it possible to set up CO2 capture and transport infrastructure even if the cost of the solution remains high. To date, the cost of a ton of CO2 avoided thanks to CCS is 100 to 150 euros.
In addition to the economic aspect, the Ecological Transition Agency warns of the “challenge of societal acceptance” implied by the CSC. Indeed, Ademe highlights “potential technological and health risks” making CSC a “risky bet” which should only enter into the decarbonisation strategy in “the last step. "
