ArcelorMittal Europe to produce ’green steel’ starting in 2020

Hydrogen technologies at the heart of drive to lead the decarbonisation of the steel industry and deliver carbon-neutral steel - Seite 2

•  Blast furnace injection across Flat Products sites

ArcelorMittal Europe is also implementing projects in almost all its Flat Products sites to use gases from different sources for blast furnace injection. Injecting hydrogen-rich coke oven gas is an efficient, cost effective method that allows steelmakers to reduce CO2 emissions now. ArcelorMittal Asturias has the most advanced coke oven gas project, with injection of grey hydrogen (hydrogen that has been recovered from gases including natural gas and coke oven gas) due to start in early 2021.

2. Hydrogen and DRI-EAF

• Testing hydrogen to reduce iron ore and form DRI, at ArcelorMittal Hamburg

ArcelorMittal Europe owns Europe’s only DRI-EAF facility in Hamburg, where a project is planned to test the ability of hydrogen to reduce iron ore and form DRI on an industrial scale, as well as testing carbon-free DRI in the EAF steelmaking process.

• Large-scale DRI plant being studied for Dunkirk

At ArcelorMittal Dunkirk a study has been launched to build a large-scale DRI plant, combined with an electric arc furnace. Initially, the DRI installation would use natural gas but ArcelorMittal’s unique experience in DRI production, together with the results of the DRI-hydrogen project in Hamburg mean the DRI installation will be fully ‘hydrogen-ready’.

SMART CARBON WITH HYDROGEN

• Second Carbalyst plant planned, in Fos-sur-Mer; further CO2 cuts with large electrolyser for hydrogen injection

ArcelorMittal is also planning to expand its use of the Smart Carbon technology route. At ArcelorMittal Fos-sur-Mer, France, a study is underway in collaboration with partner Lanzatech, to build a second Carbalyst plant in addition to the one under construction at ArcelorMittal Ghent in Belgium. This involves carbon capture from the blast furnace waste gas, and biologically converting it into ethanol for use as a biofuel or recycled carbon feedstock for the chemical industry. In parallel with the company’s electrolyser project in Bremen, the Carbalyst plant in Fos-sur-Mer will boost CO2 savings through hydrogen injection, supplied by a large-scale electrolyser that will produce the hydrogen locally from renewable electricity.
