evroc, Blykalla, and Studsvik partner to explore the development of Sweden’s first nuclear-powered data centers

• evroc joins forces with Blykalla and Studsvik to evaluate and advance the development of Sweden’s first nuclear-powered data centers.
• Combining hyperscale infrastructure, advanced Small Modular Reactors (SMRs), and licensed nuclear expertise for climate-neutral digital infrastructure.
• MoU signed to evaluate feasibility and joint steering committee to be established to assess site and business model.

6 October 2025, Stockholm – The rapid and unprecedented surge in demand for AI is putting immense pressure on energy resources, raising a critical question: How do we power this essential digital infrastructure with sustainable, fossil-free energy?

At evroc, we’re excited about the transformative potential of Small Modular Reactors (SMRs) and the opportunities they present for meeting the critical energy needs of next generation digital infrastructure. That’s why we’ve partnered with Blykalla and Studsvik to advance Sweden’s first nuclear-powered data centers.

evroc is building hyperscale cloud and AI infrastructure to power Europe’s digital future. Blykalla is developing advanced lead-cooled nuclear reactors to deliver safe, cost-effective, and sustainable baseload energy. Studsvik operates a licensed nuclear site in Nyköping and provides lifecycle services for the nuclear sector, including fuel, materials, and waste management. Together, they combine technology, infrastructure, and site expertise to accelerate the deployment of nuclear-powered data centers.

Momentum is building internationally for nuclear-powered data centers, driven by the parallel demands of AI and electrification. With their capacity to deliver clean, reliable baseload power and built-in redundancy, SMRs are particularly well suited to meet this need.

With this agreement, the parties aim to establish Sweden as a frontrunner in this global shift, leveraging evroc’s digital infrastructure, Studsvik’s licensed site, and Blykalla’s advanced SMR technology.

“The ever-growing demand for AI underscores the urgent need to rapidly deploy massive hypserscale AI infrastructure. Through our collaboration with Blykalla and Studsvik, we are exploring a model where Sweden can lead in building climate-neutral digital infrastructure," comments Mattias Åström, Founder and CEO of evroc.

“This collaboration is an opportunity for Sweden to be a leader in digital infrastructure. lt allows us to demonstrate how SMRs can provide the stable, fossil-free energy that is required for the AI revolution,” says Jacob Stedman, CEO of Blykalla. “Studsvik’s site and evroc’s ambitions offer the right conditions for a groundbreaking project.”

The MoU sets out a framework for collaboration between the three parties. The goal is to assess the commercial and technical viability of co-locating data centers and SMRs at Studsvik licensed site, engage with municipalities and landowners, and define what a future commercial power purchase agreement structure could look like.

“Studsvik’s provides a unique platform of site infrastructure and unique competence to combine advanced nuclear with next-generation industry. This MoU is an important step in evaluating how such synergies can be realized in Sweden,” comments Karl Thedéen, CEO, Studsvik.

The parties will now establish a joint steering committee to evaluate the site and business model, with the goal of entering formal partnership negotiations later this year. Their continued cooperation is set to enable clean, secure power for Europe’s AI and digital infrastructure.
