Lyngby/Denmark – Topsoe and its projects partners Skovgaard Energy and Vestas, recently marked the start of construction of the green ammonia plant in Lemvig, Denmark. Kim Grøn Knudsen, Chief Strategy and Innovation Officer at Topsoe: “We are very excited to begin this next chapter going from maturing the project to actually begin construction of this cutting-edge green ammonia plant. The plant will serve as a prime example of how we can replace fossil-based fuels and fertilizer by carbon-neutral alternatives via electrolysis.”

Pat A Han, Technical Director, Skovgaard Energy: “Today marks a great milestone for Skovgaard Energy on our Power-to-X journey. Northwest Jutland holds an immense potential for the technologies that we aspire to demonstrate in the Reddap project, and today’s event is a big step towards unfolding that potential. We are happy to start construction of our first Power-to-X plant and to celebrate this event with our project partners. We believe there will be a lot for us to learn in operating this green ammonia plant, that will help us in the preparation of up-scaled Power-to-X projects.”

An important part of the climate action plan for Lemvig Municipality is to turn the areas’ many energy resources from wind and sun into new green fuels or other future potentials.

Dynamic green ammonia plant

Green ammonia, produced from renewable energy, is an excellent fuel and fertilizer that can potentially replace significant volumes of fossil fuels and help accelerate the transition to a world powered by renewable energy. The plant will be state of the art and the world’s first so-called dynamic green ammonia plant. The dynamic approach entails that the clean power from wind turbines and solar panels will be connected directly to the ammonia plant to improve the cost-effectiveness.

The partners will collaborate closely to design the green ammonia plant’s dynamic technology to secure optimal production and adapt to the inherent fluctuations in power output from wind turbines and solar panels. This will be secured by integrating wind, solar, and electrolysis with an ammonia synthesis loop. In addition, the renewable energy generation will be connected directly to the national grid so surplus power can be sold to the grid.

Facts about the green ammonia plant

Location: Ramme near Lemvig, Western Jutland, Denmark

Output: More than 5,000 tons green ammonia annually from renewable power. This production will prevent 8,200 tons of CO2 from being emitted into the atmosphere every year.

Power supplied from renewable sources: 50 MW new solar panels and 12 MW existing V80-2.0 MW Vestas wind turbines.

The potential of green ammonia

Green ammonia has huge potential in the global effort to substitute fossil fuels with sustainable alternatives. It has been highlighted as a superior green fuel for shipping that currently accounts for around 2 % of global energy-related CO2 emissions. It can also play a vital role as a more sustainable fertilizer. Today, ammonia is used as fertilizer globally and coming from a fossil-based production, it accounts for around 1 % of global CO2 emissions.
