Topsoe Revolutionises Green Hydrogen with New SOEC Plant
Herning, Tuesday, 4 November 2025.
Topsoe’s new 500MW SOEC plant in Denmark marks a €300 million leap in green hydrogen production. This initiative promises to boost sustainable energy and reduce carbon emissions significantly.
A Green Leap Forward
Topsoe’s new 500MW solid oxide electrolysis cell (SOEC) plant in Herning, Denmark, represents a monumental €300 million investment in green hydrogen production. This facility, inaugurated on 30 October 2025, is expected to reach full capacity within a few years, significantly contributing to the global transition towards renewable energy sources [1][2].
Strategic Location and Technology
Located in Herning, this 23,000 m² facility benefits from proximity to renewable energy resources and heavy industries in Northern Europe. The plant’s SOEC technology operates at high temperatures, improving efficiency by 20-30% over traditional systems, making it a game-changer in hydrogen production [2][3].
Investment and Economic Impact
Supported by a €94 million investment from the EU Innovation Fund, the Herning plant is set to create up to 300 high-tech jobs. This aligns with Europe’s aim for at least 40 GW of renewable electrolysis by 2030, positioning Topsoe as a leader in the hydrogen market [2][3].
Tackling Global Challenges
By reducing reliance on imported hydrogen and fossil feedstocks, Topsoe’s plant addresses two significant challenges: industrial decarbonisation and energy independence. As demand for hydrogen production grows, maintaining momentum will be essential [3].
Partnerships and Future Prospects
Topsoe has already secured key partnerships, such as with First Ammonia and Forestal del Atlántico, to expand its green ammonia and e-methanol projects. These collaborations highlight the plant’s role in driving innovation and sustainability in the energy sector [2][3].
