Outokumpu Partners with Boston Metal to Advance Carbon-Free Steel Production

Finnish stainless steel producer Outokumpu has signed a memorandum of understanding with U.S.-based Boston Metal to accelerate the development of carbon-free metals. The collaboration marks a significant step toward sustainable steelmaking, aligning with global efforts to reduce greenhouse gas emissions and advance clean energy transition.

The partnership will focus on using chromium sourced from Outokumpu’s Kemi mine in Finland within Boston Metal’s molten oxide electrolysis (MOE) technology. This innovative process aims to eliminate heavy carbon emissions traditionally associated with steel production, offering a scalable solution for greener industrial practices.

Boston Metal is working to commercialize its MOE process by developing equipment capable of producing steel without fossil fuel emissions. By integrating Outokumpu’s raw materials, the companies aim to demonstrate how sustainable chromium can enhance the efficiency and performance of the carbon-free technology.

Outokumpu emphasized that this initiative supports its EVOLVE strategy for 2026–2030, which prioritizes innovation, environmental responsibility, and the transition to low-carbon steel production. “The joint development showcases our ability and commitment to drive our newly announced EVOLVE strategy forward,” said Stefan Erdmann, Chief Technology Officer at Outokumpu.

Carbon-free metals are increasingly viewed as essential to the future of renewable energy, infrastructure, and manufacturing. By reducing reliance on carbon-intensive processes, the steel industry can significantly cut emissions and contribute to global climate goals.

With steel production currently accounting for a large share of industrial CO₂ emissions, the Outokumpu-Boston Metal collaboration highlights a promising pathway for the sector. If successful, this joint project could pave the way for broader adoption of sustainable technologies, positioning both companies as leaders in the race toward carbon-neutral steelmaking.
