Following the announcement of the planned expansion of Germany’s hydrogen infrastructure, ArcelorMittal is planning to build a large-scale industrial plant for the direct reduction of iron ore (DRI) and electric arc furnace (EAF)-based steelmaking at its site in Bremen, as well as an innovative DRI pilot plant in addition to an electric arc furnace (EAF) in Eisenhüttenstadt.
Using green hydrogen, up to 3.5 million tonnes of steel could be produced by the Bremen and Eisenhüttenstadt sites by 2030, with significantly lower CO2 emissions. Depending on the amount of hydrogen available, CO2 savings of more than 5 million tonnes could be possible. The technology conversion requires investments in the range of €1-1.5 billion.
"With our concept for the transformation of the plants in Bremen and Eisenhüttenstadt, we are accelerating the implementation of carbon-neutral steel production. These projects have the potential to have a significant impact in reducing CO2 emissions, in line with the European Union’s climate commitments. We are now asking for the necessary support and access to funding to make these plans happen " said Reiner Blaschek, CEO of ArcelorMittal Flachstahl Deutschland.
In Germany, the group already operates Europe’s only DRI-EAF plant in Hamburg, where the switch to using hydrogen instead of natural gas in the iron ore reduction process is being prepared. The objective is to reach industrial commercial maturity of the technology by 2025, initially producing 100,000 tonnes of sponge iron a year.
To implement the projects, ArcelorMittal is planning to gradually adapt production in Bremen and Eisenhüttenstadt in order to be able to competitively manufacture carbon-neutral, high-quality steel using hydrogen in the iron ore reduction process.
This year, two blast furnaces – one in Bremen and one in Eisenhuttenstadt - will be converted to inject natural gas, reducing the use of coal in the iron ore reduction process and thereby further reducing CO2 emissions.
As a next step, innovative DRI-EAF plants are to be set up at both locations. In Bremen, ArcelorMittal initially plans to use natural gas for the DRI, and later hydrogen from electrolysis; the hydrogen is to be made available as part of the regional North German Clean Hydrogen Coastline network.
The sponge iron produced in the Bremen DRI unit will initially supply the steelworks in Bremen and Eisenhüttenstadt, until the regional hydrogen cluster in East Brandenburg can also supply the Eisenhüttenstadt site with sufficient hydrogen.
In the transition phase, the additional hydrogen required in Eisenhüttenstadt will be generated from natural gas with the help of a pyrolysis plant that will be built on the steel plant’s premises.
To secure the future supply of hydrogen, both sites are to be integrated into the European hydrogen network in the long term via the regional hydrogen networks.
ArcelorMittal has set itself the goal of reducing CO2 emissions by 30 percent by 2030 in Europe and producing carbon-neutral steel by 2050. To this end, ArcelorMittal is pioneering two breakthrough carbon-neutral technology routes, Smart Carbon and an innovative DRI-based route.
According to the group, the focus is on making 'smarter steels' - steels made using innovative processes which use less energy, emit significantly less carbon and reduce costs.
ArcelorMittal is the world's leading steel and mining company, with a presence in 60 countries and primary steelmaking facilities in 17 countries. In 2020, ArcelorMittal had revenues of $53.3 billion and crude steel production of 71.5 million metric tonnes, while iron ore production reached 58.0 million metric tonnes.
