Dunkirk – The "3D" industrial pilot to demonstrate an innovative process for capturing CO2 from industrial activities is now running at ArcelorMittal’s Dunkirk site. With support from the European Union’s Horizon 2020 Research and Innovation program, the project aims to validate replicable technical solutions for carbon capture. The "3D" project, driven by a consortium including TotalEnergies, ArcelorMittal, Axens and IFP Energies Nouvelles (IFPEN), is a major step towards decarbonizing industries that are highly emissive of CO2, such as steelmaking.

Final stage before full-scale deployment

The challenge for carbon capture researchers is making the processes more competitive and less energy intensive. This industrial pilot should allow the performance of the DMXTM carbon capture process developed in IFPEN’s labs over the last ten years to be verified.

The project was launched in May 2019, and the building of the demonstrator began in 2020 under Axens’ supervision. Last December, the pilot’s main modules, including a 22 meter tower, were delivered and assembled at ArcelorMittal’s site in Dunkirk. The phases of building the pilot and connecting it to the plant have now been completed, and the unit is ready for start-up.

This demonstration, which is scheduled to last for 12 to 18 months, is the final stage before the technology’s full-scale deployment.

Demonstrating performance on smokestack emissions

The carbon capture facility will process steelmaking gases: it will demonstrate the effectiveness of the carbon capture process by separating the CO2 from other gases. During the demonstration stage, it will capture 0.5 tons of CO2 an hour, i.e. more than 4,000 tons a year.

"This carbon capture pilot is a big step towards decarbonizing the industry: it is being tested in steelmaking, but can also be applied to refining processes, contributing to TotalEnergies’ net zero ambition for 2050, together with society. We need to capture and store residual emissions: that’s why our R&D teams are working alongside our partners to develop expertise throughout the CO2 capture, storage and use process. So we are using existing technologies at our Zeeland refinery in the Netherlands, we are using pilots to validate the performance of technologies that are already advanced, as is the case here in Dunkirk, and we are looking further ahead, in our research centers, to those that will deliver tomorrow’s breakthroughs,” said Marie-Noëlle Semeria, Chief Technology Officer at TotalEnergies.

Twelve partners committed to the energy transition

The project is a vital driver for reaching the targets of the Paris Agreement on Climate Change. It includes twelve partners from research and industry in six European countries: ArcelorMittal, IFPEN, Axens, TotalEnergies and its affiliate GreenFlex, ETH, DTU, AirProducts, John Cockerill, Gassco, Brevik Engineering and Seqens. The project also has two sponsors: Suez and Lhoist.
