Arcelor Mittal must present its CO2 recycling project to Jean Castex

What is this new technology that should make it possible to reduce CO2 emissions? Prime Minister Jean Castex must go to Dunkirk this Friday to attend the presentation of a decarbonization project for the Arcelor Mittal factory, partly financed by state aid.

This project, called Reuze, was to be presented to the press two weeks ago, but the meeting was postponed at the last minute for an unknown reason. whatever, 20 minutes is able to tell you a little more about this project piloted by the steel giant with its energy producing partners, Engie and Infinium.

Powerful 400 megawatt electrolyser

The Reuze project aims to produce synthetic fuels from CO2 and hydrogen in order to contribute to the decarbonisation of the transport sectors. The hydrogen will be produced by a super-powerful 400 megawatt electrolyser.

But above all, this new technology should make it possible to recycle the CO2 produced by Arcelor Mittal during the manufacture of steel. The steelmaker, which is one of the big polluters in Dunkirk, must find solutions to achieve the objective of a 35% reduction in CO2 by 2030, without reducing its production.

Capture and liquefy CO2

One of them therefore consists in capturing and liquefying the CO2 coming from the steelmaking gas of the blast furnaces, in a tower 22 meters high. “The laboratory stage validated this high-tech process. The tower should be officially inaugurated on March 8, and become operational in May,” according to a spokesperson for Arcelor Mittal.

This industrial facility should eventually make it possible to capture and recycle one million tonnes of CO2 per year. It will be coupled with the construction of a new coal-free steel production unit, but with hydrogen. This new equipment, also capable of reducing CO2 production, should be operational in 2027. It’s still that much less in the Dunkirk atmosphere…
