ArcelorMittal joins biogas project in Luxembourg

Vow ASA, a specialist provider of technology for decarbonising industries, has signed a memorandum of understanding with ArcelorMittal to build a biogas production plant that will reduce CO2 emissions from steelmaking.

Vow subsidiary ETIA and ArcelorMittal’s Europe – Long Products unit will work together to build what they claim is the first dedicated biogas plant for the steel industry, using ETIA’s pyrolysis technology. It will be built at ArcelorMittal Rodange in Luxembourg, which specialises in the production of grooved rail.

The partners aim to have the Rodange biogas plant operational in 2023. The biogas will be made using Vow’s patented “Biogreen” pyrolysis technology, which involves heating sustainable biomass at high temperatures. The gases emitted during this process are then captured and processed into biogas, which will directly replace the use of natural gas in the Rodange plant’s rolling mill reheating furnace, Kallanish understands.

By-products such as bio-coal will also be created during the process, and re-used within ArcelorMittal, directly replacing the use of coal, the steelmaker states.
