Danish electrolyzer manufacturer Topsoe has received a firm order to deliver 55MW of solid-oxide electrolyzers (SOEs) for Forestal del Atlántico’s Triskelion e-methanol project in Mugardos, Galicia, marking the largest SOE-based facility yet announced worldwide.
Project context and european policy backdrop
The deal positions Topsoe’s high-temperature electrolysis technology at the centre of one of Europe’s most advanced e-methanol ventures, as the EU accelerates funding and deployment of renewable hydrogen-based fuels under its Innovation Fund and Fit for 55 framework. The Triskelion project was awarded €49mn from the Innovation Fund in 2023 and aims to start operations in 2028, following a final investment decision (FID) scheduled for Q2 2026.
TOPsoe Project scope and technical details
Under the agreement, Topsoe will supply its SOE units and integrated e-methanol synthesis technology, catalysts and engineering services. The system will use 55MW of renewable electricity to produce hydrogen, which will be combined with 78,000 tonnes of captured CO₂ annually to yield around 57,000 tonnes of e-methanol. Forestal plans to use the synthetic fuel to replace fossil methanol in its glue and resin production, while also targeting potential maritime fuel markets.
Topsoe said the installation will be the first commercial deployment of its solid-oxide technology for e-methanol. The company’s system integrates hydrogen generation and methanol synthesis in a single process, which it claims improves overall efficiency by up to 30 per cent compared with conventional alkaline or PEM electrolysers and removes the need for intermediate hydrogen storage. “Our integrated SOEC and e-methanol technology will enable Forestal to decarbonise its chemical production value chain,” said Sundus Cordelia Ramli, Topsoe’s chief commercial officer for Power-to-X.
Forestal’s general manager, Andrés Fuentes, described the partnership as placing the Triskelion project “in a leading competitive position within the e-methanol sector,” citing efficiency gains and the potential to strengthen Spain’s position in renewable fuels manufacturing.
Manufacturing and market outlook
Topsoe will deliver the electrolysers from its Herning factory in Denmark, which is nearing full industrial-scale production readiness. The company will also provide a ten-year service warranty. Its order book includes another 100MW SOE contract with US developer First Ammonia for a Texas green ammonia project, highlighting growing commercial interest in solid-oxide systems despite their higher upfront cost and shorter stack lifetimes compared with other electrolyser types.
Solid-oxide electrolysers operate at around 800°C, enabling higher hydrogen output per unit of power when waste heat is available — an efficiency advantage that could be decisive for projects co-located with industrial emitters. However, their commercial rollout remains limited due to cost and durability concerns.
Implications for europe’s hydrogen economy
If the Triskelion project proceeds as planned, it would mark a significant test case for SOE scalability in Europe’s hydrogen economy. For investors and policymakers, its progress will indicate whether high-temperature electrolysis can complement or compete with lower-temperature technologies in achieving the EU’s targets for green hydrogen and synthetic fuels.
