Sweden’s ambitions to become a global leader in fossil-free steel are gaining momentum as Thyssenkrupp Nucera prepares to deliver electrolysers to Stegra’s flagship hydrogen-powered steel plant in Boden.
The €100 million contract between Thyssenkrupp Nucera and Stegra—announced in February—covers the supply of up to 37 alkaline electrolyzer modules, each rated at 20MW. These units will collectively form a 740MW green hydrogen production facility, designed to fuel Stegra’s decarbonized steelmaking process. Each electrolyzer module, built in Tarragona, Spain, spans 40 meters in length and six meters in height, reflecting the scale of the undertaking.
Stegra CEO Henrik Henriksson confirmed the project milestone via LinkedIn, noting that his team had visited the manufacturing site to inspect the assembly of the hydrogen systems ahead of shipment to northern Sweden.
Green hydrogen will play a central role in Stegra’s approach to steel decarbonization. Located on a 70-hectare site in Boden, the green hydrogen plant will supply the necessary feedstock for direct reduction of iron, eliminating the need for coal in the steelmaking process. Henriksson referred to the facility as one of the “most fascinating processes” in the entire project.
Backed by a €100 million grant from the Swedish Energy Agency secured in September 2023, Stegra’s plant is set to begin steel production in 2026. The company aims to ramp up to five million tonnes of green steel annually by 2030—a target that would position it among Europe’s largest producers of fossil-free steel.
