Dynamic green ammonia plant starts production for shipping in Denmark

Topsoe and its partners Skovgaard Energy and Vestas have recently 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 optimises operations and ensures less need for costly storage solutions of green hydrogen or renewable power.

Kim Hedegaard, CEO Power-to-X at Topsoe, said: “This is a significant achievement. By working across the value chain, we’re accelerating green ammonia as a pathway to diversify our energy supply and decarbonize energy-intensive industries and long-distance transportation like shipping and agriculture.”

Niels Erik Madsen, CEO at Skovgaard Energy, said: “We are extremely proud of this groundbreaking project in Northwest Jutland driving innovation, growth and job creation locally. It demonstrates the energy systems of tomorrow – scalable worldwide to accelerate the green transition.”

Topsoe delivers the ammonia technology, and Vestas delivers renewable wind power adding to the power provided from Skovgaard Energy’s solar panels and wind turbines.

Ammonia – either in the form of low-carbon ammonia or as an e-fuel – is expected to play a critical role in the world’s fuel mix. It can be transported using existing infrastructure; and it has multiple end-uses, not only as a fuel or hydrogen carrier but also to help decarbonize industrial processes like agriculture, shipping and steel production.

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 metric tonnes (mt) of green ammonia annually from renewable power. This production will prevent approximately 9,600 mt 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.
