Technology Partner Topsoe

First Ammonia and Partners visit the Topsoe Factory in Denmark, October 2024

Partnered on the Next-Generation Electric Ammonia Plant

First Ammonia is partnered with Topsoe on the future of electric ammonia through a 5 GW electrolyzer capacity reservation agreement.

Using Topsoe’s solid oxide electrolyzer cells (SOEC) integrated with an ammonia loop maximizes the amount of ammonia produced per watt of electricity.

Thanks in part to the First Ammonia-Topsoe partnership, Topsoe constructed a 500 MW per year SOEC factory in Herning, Denmark. Manufacturing began in 2024.

Topsoe’s History of Excellence

Topsoe is a Danish company with a strong reputation for excellence in engineering since its founding by Dr. Haldor Topsøe in 1940. For more than 80 years, Topsoe has delivered ammonia solutions to projects around the world.  

Expertise on solid oxide electrolyzers and ammonia synthesis gives Topsoe a unique advantage in designing high-performance, electric ammonia systems.

Advantages of Topsoe’s Integrated SOEC – Ammonia Technology

Proven Approaches

Core at Frederickssund running for +2000 hours stable performance as of March 2024, efficiencies of 36 kWh/kg H2, and ramp of 0% to 100%

Solid Oxide Electrolyzer Core

Topsoe demonstrated the consistent performance of its solid oxide electrolyzer core at its Frederikssund facility. The core has been running under industrial conditions since 2023.

The SEOC core performed well in the fluctuating operational mode required to run on variable solar and wind power generation.

Dynamic Ammonia Loop

Topsoe demonstrated the fluctuating ammonia loop at the electric ammonia plant in Ramme, Denmark. In partnership with Skovgaard Energy and Vestas, the plant showed how an ammonia plant can directly be coupled with fluctuating renewable power.
