Outokumpu explores cutting carbon emissions in stainless steel production using small modular reactors. Investigating the feasibility of SMR technology, Outokumpu aims to accelerate industrial decarbonization in line with ambitious sustainability goals. Positioned as a leader in sustainable stainless steel, the company considers SMRs for stable, CO₂-free electricity, potentially impacting not only electricity production but also district heat, hydrogen, and process heat.


In a bid to revolutionize stainless steel production and reduce carbon dioxide emissions, Outokumpu is delving into the potential of small modular reactor (SMR) technology. These reactors, compact and pre-fabricated, offer a promising avenue for sustainable energy. Outokumpu, committed to the Science-Based Targets initiative’s 1.5°C climate goal, seeks to bolster its decarbonization efforts by evaluating the feasibility of integrating SMRs into its operations.

Kristiina Tiilas, Head of the SMR nuclear project at Outokumpu, explains the versatility of SMRs, capable of delivering not only electric power but also district heat, hydrogen, and process heat. The pre-research phase, currently underway, encompasses technical solutions, financial viability, and environmental impacts. This investigation sets the stage for assessing the practicality of investing in SMRs, a move that aligns with Outokumpu's position at the forefront of decarbonizing the steel industry.

Tony Lindström, Head of Outokumpu’s energy strategy, emphasizes the company's commitment to leveraging evolving technologies for carbon reduction. The potential deployment of SMRs holds the promise of not only minimizing construction costs but also expediting the construction timeline, marking a significant stride toward Outokumpu's sustainability objectives.


Outokumpu's exploration of small modular reactor (SMR) technology underscores its commitment to pioneering sustainability in stainless steel production. The potential benefits, ranging from reduced carbon emissions to diversified energy outputs, align with the company's ambitious climate targets. As the investigation progresses, Outokumpu aims to solidify its position as an industry leader in decarbonization, emphasizing the crucial role of evolving technologies in achieving lasting environmental impact.
