On May 19, 2026, Stargate Hydrogen stated it successfully delivered its 1 MW alkaline electrolyser to the newly opened Kalla Test Center of Fortum in Loviisa, Finland. The facility is an important step for both companies, as Stargate Hydrogen tech is proving reliable and Fortum is beginning the long-term operational evaluation of hydrogen production.
The Kalla Test Center is a pilot-scale hydrogen production facility from Fortum for testing of hydrogen technologies in real operational conditions. Until 2028 the site will be a platform for operational know-how, technology validation, along with future project development.
Kalla is one of the first hydrogen sites in the Nordics for evaluating two different electrolyser technologies simultaneously. The facility has two different electrolyser systems in operation, one from Stargate Hydrogen.
The project involves an investment of €20 million in construction as well as operational stages. Site preparation for the ~2 MW hydrogen production facility started in autumn 2024, with construction starting in summer 2025. The first hydrogen was made in commissioning in December 2025, and the site is anticipated to be completely operational in the summer of 2026.
The inauguration is a significant achievement for Stargate Hydrogen. Successful installation of the electrolyser technology of the company at Kalla is a clear demonstration of its preparedness for industrial uses and strategic energy initiatives throughout Europe.
According to the CEO of Stargate Hydrogen, Marko Virkebau, “The inauguration of the Kalla Test Center proves that Stargate Hydrogen has reached the maturity level required to be trusted by large industries. “Delivering this project together with Fortum shows that our technology and our team are ready to support the growing hydrogen economy in the Nordics and beyond.”
Fortum’s Kalla Test Center is the first move towards gaining real-world expertise in hydrogen production as well as industrial decarbonisation.
Remarks the Vice President, P2X & Project Execution at Fortum, Satu Sipola, “At Kalla, we are building the practical experience needed to develop hydrogen solutions. This step-by-step approach is essential to ensure both technical readiness and commercial viability, and Stargate Hydrogen tech demonstrated a high level of reliability and professionalism from start to finish.”
