Everfuel’s Hysynergy Plant becomes world’s first facility to stabilise power grid while producing green hydrogen

For the first time worldwide, Everfuel is using a large-scale electrolyser plant, HySynergy, to provide balancing services to the power grid while simultaneously producing certified green hydrogen (RFNBO).

This milestone demonstrates how green hydrogen production can actively support the electricity system and create a flexible, sustainable energy supply for the benefit of Danish society.

With the HySynergy facility in Fredericia, Everfuel shows that electrolysis is not only a technology for producing green hydrogen, it is also an active tool for stabilising the grid. Everfuel, Energinet and Centrica have long collaborated to integrate HySynergy as balancing capacity in the electricity system, making it the first PtX plant in Denmark to do so. Today, this vision has become a reality. This achievement paves the way for electrolysis plants such as HySynergy to participate in Energinet’s balancing services going forward.

Jacob Krogsgaard, CEO and Founder of Everfuel, said: “Today, we have accomplished something that Denmark has discussed for years. We have proven that green hydrogen production can be fully integrated into the energy system, not only as a molecule, but as an active balancing instrument. This is a crucial step toward realising Denmark’s and Europe’s green ambitions and creating a robust, climate-friendly energy infrastructure. As the first in the world, Everfuel can now contribute to grid balancing while producing certified green hydrogen. It is a milestone in Danish and global energy history, one that Everfuel, Energinet, Centrica and all our partners can be proud of.”

Kim Willerslev Jakobsen, Director of System Responsibility, Energinet, added: “One of the biggest challenges in the green transition is maintaining constant balance in the power grid as we integrate increasing amounts of renewable electricity from solar and wind. We already have many different actors in the balancing market that can adjust their consumption – power plants, heat pumps, batteries, electric vehicles, greenhouses and even an ice rink. And now, for the first time in the world, we also have a Power‑to‑X facility. This is a historic milestone showing the right direction, and at Energinet we share the excitement and pride in the project.”

Kristian Gjerløv‑Juel, VP Renewable Energy Trading & Optimisation, Centrica Energy, concluded: “This milestone demonstrates what can be achieved through innovation and collaboration. By integrating green hydrogen production with aFRR balancing, we are delivering a solution that both supports the green transition and contributes to a more sustainable energy market. We are proud to be part of this development together with Everfuel.”
