Sweden advances in the implementation of a hydrogen plant to revolutionize steel production

The energy transition of the steel industry has taken a significant leap forward in Sweden with the progress of construction on Stegra's low-carbon hydrogen plant. In just six months, the four immense buildings that will house the central electrolyzers are nearly completed, and the first process equipment has already been installed. The plant represents a milestone in the replacement of conventional and highly polluting iron and steel production methods with clean energy-based alternatives.

Cutting-edge technology and ambitious goals by 2028

At the heart of the facility are Thyssenkrupp electrolyzers with a capacity of 20 megawatts each, measuring 40 meters long by nine meters high. These devices use alkaline electrolysis powered by 100% renewable electricity to produce more than 100,000 tons of hydrogen per year—an essential element for the CO₂-free direct reduction process of iron ore.

The hydrogen will be used to convert iron ore into green iron, generating only water as a byproduct. Starting in 2026, Stegra will begin producing steel from recycled scrap, followed shortly thereafter by producing green iron, with a view to large-scale expansion by 2027. The goal is to reach full operation of its hydrogen, iron, and green steel units by 2028, solidifying Sweden as a leader in sustainable steelmaking.
