Today, in a Direct Reduced Iron (DRI) furnace fed with natural gas (CH4), approximately 50% of the reaction comes from hydrogen (H2), and the remainder from carbon monoxide.
Technologies can be developed to increase the proportion of hydrogen fed into the shaft furnace up to 100%. Where renewable energy is used to produce ‘green hydrogen’ for use in this way, it directly displaces CO2. However, where insufficient levels of renewable energy are available, industry will need to use ‘blue’ hydrogen, derived directly from fossil fuels or industrial gases and combined with carbon capture and storage (CCS) to ensure carbon neutrality.
ArcelorMittal is developing a new, innovation project at our Hamburg site in Germany aimed at the first industrial scale production and use of Direct Reduced Iron (DRI) made with 100% hydrogen as the reductant, with an annual production of 100,000 tonnes of steel.
The process of reducing iron ore with hydrogen will first be tested using grey hydrogen generated from gas separation. We aim to achieve the separation of H2 with a purity of more than 97% from the waste gas of the existing plant, using a process known as ‘pressure swing absorption’. This will allow us to develop technological solutions at industrial scale to reduce iron ore with only Hydrogen and in absence of carbon. Many technical and practical challenges are ahead of us, which only can be solved in an operational plant, something that has never been done up to now due to lack of hydrogen infrastructure.

In the future, the plant should also be able to run on green hydrogen when it is available in sufficient quantities at affordable prices, with the clean energy for hydrogen production potentially coming from wind farms off the coast of Northern Germany.
In September 2019, ArcelorMittal announced the signing of a Framework Collaboration Agreement (FCA) with Midrex Technologies to design the Hamburg demonstration plant and work on several related R&D and innovation projects.
“We are working with a world class provider, Midrex Technologies, to learn how you can produce virgin iron for steelmaking at a large scale by only using hydrogen. This project, combined with our ongoing projects on the use of non-fossil carbon and on carbon capture and use, is key to becoming carbon neutral in Europe in 2050. Large-scale demonstrations are critical to show our ambition. However, how fast transformation will take place will depend on the political conditions.” Carl de Maré, Vice President at ArcelorMittal and responsible for technology strategy.
ArcelorMittal Hamburg already produces steel using DRI technology. During the process, iron oxide pellets are reduced to metallic iron, the raw material for high quality steel, by extracting oxygen using natural gas. “Our site is the most energy-efficient production plant at ArcelorMittal”, says Dr Uwe Braun, CEO at ArcelorMittal Hamburg, adding that the existing Midrex plant in Hamburg is also the plant with the lowest CO2-emissions for high quality steel production in Europe.
“With the new, hydrogen-based DRI plant we are now planning, we will raise steel production to a completely new level, as part of our Europe-wide ambition to be carbon neutral by 2050” Dr Braun concludes.
Hamburg Moorburg has something. Something that other sites don’t have. Where coal delivered energy yesterday, in the near future, green hydrogen will be produced from renewable energy sources and therefore energy for mobility, heat, process gas or natural gas replacement. Because here, in the heart of the port of Hamburg, we use wind and solar power to split water into hydrogen and oxygen in a large electrolyser. The Hamburg Green Hydrogen Hub (HGHH) is one of the first projects worldwide to decarbonize an entire port economy. Industry and transport in particular have a high demand for zero-carbon hydrogen energy. If all permits are granted on time, hydrogen production can start in 2025.
– Great generating capacity for onshore and offshore wind-generated electricity with further expansion potential
– Underground formations for storing hydrogen
– Seaports whose import terminals will play decisive roles as logistics and business hubs when it comes to importing and distributing green hydrogen and synthetic energy carriers, as well as for using hydrogen and exporting hydrogen-related technology and components
– Maritime enterprises and scientific expertise
– Industry sectors with significant experience in handling hydrogen.
Additional know-how is being generated in the six North German ‘Regulatory Sandboxes for the Energy Transition’.
For more information on these developments, read the Hydrogen Strategy for North Germany from the Ministries of Economy and Transport of the North German Coastal States.
To accelerate the transition process, twelve Hamburg-based stakeholders have joined forces to establish the Hamburg Hydrogen Network (Wasserstoffverbund Hamburg). The founding members are Airbus, ArcelorMittal, Gasnetz Hamburg, GreenPlug, Hamburger Hafen und Logistik AG (HHLA), Hamburg Port Authority, HADAG Seetouristik und Fährdienst as well as Stadtreinigung Hamburg and the Green Hydrogen Hub, which comprises Shell, Mitsubishi Heavy Industries and Wärme Hamburg.
The green hydrogen produced by the Green Hydrogen Hub will be mainly used to replace fossil fuels in industrial production as well as in the transport and logistics sectors. In addition to the use of hydrogen, the use of waste heat from electrolysis for the district heating grid and the thermal treatment of municipal waste will also contribute to reducing the ecological footprint of several other industries too.
The foundations for establishing a comprehensive hydrogen value chain in Hamburg are being laid through the scheduled conversion of a coal power plant in the Moorburg quarter into a scalable 100-megawatt electrolysis facility for the production of green hydrogen from renewable energies. Hamburg’s port, Europe’s largest industrial area, with its extensive network of potential industrial applications and service partners, provides a unique local platform for this.
The Hamburg Hydrogen Network is part of a large-scale campaign initiated by the German government. As part of the campaign, a total of 62 hydrogen projects are being supported nationwide. The campaign is jointly funded by the Federal Ministry for Economic Affairs, the Federal Ministry of Transport and the federal states to the tune of 8 billion euro. Of this, 520 million euro are being allocated to Hamburg-based projects, with a total investment volume of 1.6 billion euro earmarked for the region.
