Agreement on electrolyser technology for methanol plant

Topsoe has signed an offtake agreement to provide its Solid Oxide Electrolyser Cell (SOEC) technology for Forestal’s Triskelion green methanol plant in Galicia. The SOEC’s will be delivered from Topsoe’s manufacturing facility in Herning, Denmark, which is nearing the final stage of readiness for industrial-scale production. The agreement, which includes a 10-year service warranty program, builds on Topsoe’s existing agreement with Forestal, announced in December 2024, to provide its e-methanol synthesis technology, catalysts and engineering for highly efficient e-methanol production.

Topsoe says that, by providing a single, integrated hydrogen-to-methanol pathway, it minimises interface risk, improves overall efficiency by up to 30% compared to conventional electrolysis systems and removes the need for intermediate hydrogen storage. This ensures stable operations even during renewable power fluctuations, a crucial requirement for Forestal when assessing project risks.

The Triskelon project is designed to produce 57,000 t/a of green methanol and will capture and use 78,000 tons of CO2 each year to produce it. Power will be supplied from renewable sources through power purchase agreements, ensuring renewable and continuous power supply during operation. The plant received a euro 49 million grant from the European Union Emissions Trading System’s Innovation Fund in 2023. It is expected to begin operations in 2028.

Proton Ventures joins Barents Clean Ammonia project

Barents Blue AS has announced Proton Ventures as a new partner in the Barents Clean Ammonia Project (project formerly known as the Barents Blue project). Barents Blue says that the Dutch engineering and project development company, a pioneer in the clean ammonia industry, “will bring significant resources and industry expertise to the project and the value chain for clean ammonia, important for the realisation of Europe’s largest clean ammonia production plant located in Finnmark, Northern Norway”.

Dynamic green ammonia plant starts operations

A consortium including Danish companies Skovgaard Energy, Topsoe and Vestas says that it has reached an important milestone with the startup of operations in what they describe as the world’s first-of-its-kind green ammonia plant. The plant, owned by Skovgaard Energy and located in Ramme Denmark, is a demonstrator for a dynamic approach to green ammonia production, which means that the plant will adapt to the inherent fluctuations in power output from the renewable power sources in integration with the plant’s electrolysis and ammonia synthesis loop. This, say the developers, will ensure optimal production and improve the cost-effectiveness of green ammonia, ensuring less need for costly storage solutions of green hydrogen or renewable power. Production capacity is 5,000 t/a of green ammonia, with an associated CO2 reduction of 9,600 t/a. The partnership has received euro 11 million in funding from the Danish Energy Technology Development and Demonstration Program (EUDP).
