World’s first dynamic green ammonia plant starts operations in Denmark
12/22/2025 12:00:00 PM
- The partnership between Danish companies Skovgaard Energy, Topsoe and Vestas has reached an important milestone: The world’s first-of-its-kind green ammonia plant has started operations.
- The plant, owned by Skovgaard Energy and located in Ramme Denmark, demonstrates how renewable power can be coupled directly to an ammonia plant while taking the fluctuations in power production into account without having a hydrogen storage.
- Annual production capacity is 5,000 tons of green ammonia, with a CO2 reduction of 9,600 tons.
- The partnership has received DKK 81 million (app. EUR 11 million) in funding from the Danish Energy Technology Development and Demonstration Program (EUDP).
Topsoe and its partners Skovgaard Energy and Vestas have reached a major milestone in their partnership: The world’s first dynamic green ammonia plant is now in operation and producing green ammonia.
First of a kind, the plant demonstrates a dynamic approach, which entails 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 will ensure optimal production and improve cost-effectiveness of green ammonia.
The dynamic approach is important as it optimizes operations and ensures less need for costly storage solutions of green hydrogen or renewable power.
Facts about the green ammonia plant
- The plant is a demonstration project, which have received funding from the Danish Energy Technology Development and Demonstration Program (EUDP)
- Location: Ramme near Lemvig, Northwest Jutland, Denmark.
- Output: 5,000 tons of green ammonia annually from renewable power. This production will prevent approximately 9,600 tons of CO2 from being emitted into the atmosphere every year
- Power input: 50 MW new solar panels and 12 MW existing V80-2.0 MW Vestas wind turbines.
