Everfuel has broken new ground in the energy world.
For the first time ever, the company is using a large-scale electrolyser plant, HySynergy, to provide balancing services to the power grid while simultaneously producing certified green hydrogen (RFNBO).
The achievement marks a milestone in demonstrating how green hydrogen production can actively support electricity systems and deliver a flexible, sustainable energy supply for Danish society.
With HySynergy, Everfuel proves that electrolysis is not just a method for producing hydrogen—it is a powerful tool for stabilising the grid. The project is the result of long-standing collaboration between Everfuel, Energinet, and Centrica, integrating HySynergy as balancing capacity in Denmark’s electricity system.
“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,” said Jacob Krogsgaard, CEO and Founder of Everfuel.
“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,” said Kim Willerslev Jakobsen, Director of System Responsibility, Energinet.
“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,” added Kristian Gjerløv‑Juel, VP Renewable Energy Trading & Optimisation, Centrica Energ.
