First-of-its-Kind Project Air Liquide’s Carbon Capture Technology Used for Decarbonizing Lhoist’s Lime Production Unit
Under a MOU signed between Air Liquide and Lhoist, both the companies will work together to decarbonize Lhoist’s lime production plant in France with the use of Air Liquide’s carbon capture technology. With this project, the company aims to reduce more than 600,000 tons of CO2 emissions annually.
Paris/France – Air Liquide and Lhoist have signed a Memorandum of Understanding (MOU) with the aim to decarbonize Lhoist’s lime production plant located in Réty, in the Hauts-de-France region, using Air Liquide’s innovative and proprietary Cryocap carbon capture technology. In this context, Air Liquide and Lhoist have jointly applied for the European Innovation Fund large scale support scheme. This partnership is a new step in the creation of a low-carbon industrial ecosystem in the broader Dunkirk area.
Lime is one of the ‘hard-to-abate’ industries as its production primarily generates CO2 from decomposition of limestone. The ‘Chaux et Dolomies du Boulonnais’ Lhoist’s site in Réty is France’s largest lime production plant. Thanks to this project, Lhoist would be able to reduce the CO2 emissions of the plant in Réty by more than 600,000 tons per year starting in 2028. This is equivalent to the annual emissions of about 55,000 households in France.
Air Liquide would build and operate a unit of its innovative and proprietary Cryocap FG (Flue Gas) technology to capture and purify 95 % of the CO2 arising from Lhoist’s existing lime production unit in Réty. Air Liquide’s Cryocap technology would thus be used for the first time to decarbonize lime production in France.
The captured CO2 would then be transported to a multimodal CO2 export hub in Dunkirk, currently under development, and sent to be sequestered in the North Sea as part of the D’Artagnan project, which has received the PCI (Project of Common Interest) label from the European Commission.
The implementation of the project will be possible as public funding from European and/or French schemes supporting decarbonization become available. In this perspective, Air Liquide and Lhoist have jointly applied for the European Innovation Fund large scale call.
Cedric De Vicq, Lhoist CEO Europe, said: “As a leader in the lime industry, we are very proud that for the first time, a lime plant will capture its CO2 emissions and store them in safe conditions. Carbon Capture & Storage is an indispensable part of how the lime industry addresses the reduction of its CO2 footprint for the benefit of the environment and its customers.”
