St1 joins forces with Novatron Fusion Group to accelerate fusion energy in the Nordics
19.3.2025 09:07:02 EET | St1 | Press release
St1 and Novatron Fusion Group (NFG) have entered into a strategic, long-term industrial partnership, marking a new chapter in the journey toward commercial fusion energy. St1 takes up the role as lead investor and new board member after an investment of EUR 13 million in NFG to provide long-term value as well as business, industrial and regulatory knowledge.

The strategic, long-term partnership is a demonstration of how two Nordic companies combine their respective strengths within science and industry to reach an ambitious shared goal - to reduce societies dependence on fossil fuels while meeting the future growing energy demand.
NFG’s unique NOVATRON fusion solution is a groundbreaking technology with game changing potential, which theoretically and numerically has been demonstrated to overcome challenges with poor confinement and plasma instabilities that have obstructed the commercial advancement of fusion energy. Although the NOVATRON is not a guarantee for solving future energy demands, St1 believes that NFG has a formula that potentially could be developed into commercial and scalable fusion energy solution that is also safe and fossil-free.
"To reach our vision of being the leading producer and seller of CO2-aware energy, we will continue to invest in our value chains and ongoing projects to remain at the forefront of the energy transition. At the same time, St1 also needs to invest in technologies that are not yet commercially available, as nearly 50 percent of the carbon emission cuts required by 2050 will rely on innovations currently in the demonstration or prototype phases. We believe that NFG has a game changing formula and as an owner with a long-term mindset, we are excited over this opportunity to help accelerate the work towards limitless fossil-free energy", says Henrikki Talvitie, CEO of St1.
The partnership was formed shortly after an announcement that the first prototype of NFG’s unique NOVATRON fusion solution was assembled and the system integration tested. NFG will continue running experiments with the first prototype, N1, located at KTH Royal Institute of Technology in Sweden. In parallel, NFG is preparing for the next phase of its roadmap where long-term partnerships will be key.
"St1 operates in an industry that needs to transform and has a proven track record of genuinely wanting to accelerate the reshaping of the energy system. As we start preparing for industrialization, we need to secure these types of partners that can contribute with experience, regulatory knowledge an extensive global network, and a strong position in the energy market", says Peter Roos, CEO of Novatron Fusion Group.
By jointly investing in the game changing NOVATRON technology, the goal with the industrial partnership is not only to support energy resilience in the Nordics, but rather to make a positive impact on a global scale by securing a leading position in providing fossil-free, safe, affordable, and abundant energy for all.
