Case Study: Impact of R&D on Low-Emission Steelmaking

In 2022, a Scandinavian steel producer launched a full-scale pilot plant dedicated to fossil-free steelmaking, leveraging years of targeted R&D. The core innovation was the use of biogenic reductants—derived from forestry byproducts—instead of traditional coke. This approach not only reduced direct CO₂ emissions by over 80%, but also utilized a renewable resource that would otherwise be considered waste.

Further R&D efforts led to the integration of oxygen-blown flash smelting, a technology previously untested at this scale for steel.
