BMW plans to source steel produced with Swedish green power and hydrogen

The BMW Group continues to push forward with climate protection and is systematically pursuing its goal of significantly reducing CO₂ emissions at their source in the supply chain. From 2025 on, the company plans to source steel produced with up to 95% less CO₂ emissions and without requiring fossil resources such as coal. The BMW Group has now reached an agreement to this effect with the Swedish startup H2 Green Steel, which uses hydrogen and only green power from renewable energies for steel production. Owing to its particularly energy-intensive manufacturing process, steel production is considered one of the main sources of global CO₂ emissions.

“Our goal is to reduce CO₂ emissions in our steel supply chain by about two million tonnes by 2030. Sourcing steel produced using hydrogen and green power can make a vital contribution to this,” says Dr Andreas Wendt, member of the Board of Management of BMW AG responsible for Purchasing and Supplier Network. “Steel is essential for producing cars and will be no less important for future vehicle generations. Innovative technologies that enable virtually carbon-free production of steel have a significant impact on our ability to reduce CO₂ emissions in our steel supply chain.”

Closed-loop material cycle
In addition to the delivery of steel produced using green power, the BMW Group and H2 Green Steel have also agreed to create a closed-loop material cycle. H2 Green Steel will take back sheet metal remnants, such as those produced at press plants when doors are punched out, and will process them in such a way that they can be shipped back to the plants as new steel rolls, also known as steel coils. In this way, raw materials can be used multiple times in a circular economy and natural resources protected. Since it requires less energy to produce, secondary steel lowers CO₂ emissions by an average of 50-80%, compared to primary material.

The BMW Group is already using between 20% and 100% secondary steel in its vehicles and will continue to increase this percentage in the future. BMW Group press plants in Europe process more than half a million tonnes of steel per year.

Ideal location in northern Sweden

H2 Green Steel is building its steel production site in the province of Norrbotten in northern Sweden, close to the Arctic Circle. The region is best known for its reindeer and spectacular northern lights, but also provides access to high-quality iron ore, plentiful energy from renewable sources such as hydroelectric and wind power, a major seaport and generations of steel production know-how.

Unlike conventional processes that rely on coke for making steel, the company employs hydrogen produced using green power to remove the oxygen from the iron oxide. This so-called direct reduction of iron ore produces almost no CO₂ at all, only water – thereby avoiding 95% of the CO₂ emissions normally produced. The specially built hydrogen power plant, which uses water and green power from across the region, will be directly integrated into the steel production plant. The company also uses local green power for the remainder of the manufacturing process.
