A dynamic future of green ammonia with Skovgaard Energy

A first of its kind green ammonia plant has started operations in Ramme, Denmark.

Project highlights

Located in Ramme, Northwest Jutland, Denmark, three powerhouses in energy have teamed up to create a new chapter in green ammonia production. Partnered with Skovgaard Energy and Vestas, Topsoe has created a first of its kind green ammonia plant that is specifically designed to use the surplus power from the area's 87,000 solar panels and six 2MW wind turbines to produce roughly 5,000 tons of green ammonia a year.

In order to harness and store a maximal amount of renewable energy, the plant will demonstrate a dynamic approach, which entails that the plant will adapt to the inherent fluctuations in renewable power output in integration with the plant’s electrolysis and ammonia synthesis loop. This will ensure optimal production and improve cost-effectiveness.

The plant is a demonstration project, which have received funding from the Danish Energy Technology Development and Demonstration Program (EUDP).

Key facts

Impact: 8.200 tons of CO2 reduction

Topsoe's role

To leverage and store the regions ample renewable energy supply, the REDDAP plant uses Topsoe’s green ammonia loop, a technology specially designed for efficient dynamic operation. Topsoe’s ammonia loop allows for continuous operation and avoids shutdowns that are commonly caused with fluctuations in energy supply. With dynamic ramp-up and ramp-down rates of up to 3% per minute, this ammonia loop can rapidly respond to power variability and can operate at feed flows as low as 10% of maximum capacity, to ensure consistent output without costly shutdowns.

While the REDDAP plant is designed as a demonstration plant to showcase the possibilities of this technology, the efficiencies demonstrated by Topsoe’s ammonia loop are critical is showcasing the overall potential and profitability of this plant set-up.

The importance of green ammonia

As a multipurpose, low-carbon product that is increasingly being seen as a gamechanger in decarbonizing shipping, agriculture and several other key industries, green ammonia is showing all the signs of exponential market growth.

To meet this projected demand and further the green energy transition, it is vital that green ammonia production proves to be sustainable and profitable – and this all comes down to the quality of a plant's ammonia loop and it's ability to maximize it's use of variable renewable energy.

By maintaining outstanding performance throughout its lifecycle, the right ammonia loop can overcome the complexity involved in synthesizing ammonia from nitrogen and green hydrogen, and become the backbone of a profitable green ammonia plant. This is why plants like REDDAP are essential, they demonstrate the true potential of what can happen when the right partners, high ambition and world-class technology come together to create decarbonization solutions.
