Aquamarine is developing a large-scale green ammonia facility to be constructed in multiple stages. In the first stage of the project, the proposed facility will use Topsoe’s proprietary solid oxide electrolyzer cells (SOEC) to produce green hydrogen from 100 MW of renewable electricity. The hydrogen will be further processed into 300 t/d of green ammonia, also using Topsoe technology. The produced ammonia can be used as a green marine fuel or as fertilizer.

Aquamarine will develop the project and seek relevant permits for the project, which will be located in northern Germany close to existing offshore wind farms, where the product can be sold to the marine shipping industry.

Topsoe is already engaged in several projects to produce green hydrogen, green ammonia, eMethanol, and green fuels. An example is the Helios project in NEOM, Saudi Arabia, announced in July 2020, which includes the world’s largest ammonia loop (1.2 MMt/year) delivered by Topsoe. With the SOEC technology and decades of experience as a world-leading technology provider within ammonia, methanol, gasoline, jet-fuel, diesel, and hydrogen, Topsoe is one of the very few companies that can deliver insights, technology and catalysts along the entire value chain for next-generation fuels and chemicals.

Facts about the facility

• The facility’s electrolysis unit will have a 100-MW capacity.
• The product will be green hydrogen to be fully converted to green ammonia – 300 t/d.
• The technology will be Topsoe’s proprietary high-temperature electrolysis SOEC technology offering up to 30% larger green hydrogen output compared to standard technology such as PEM and alkaline electrolysis.
• Subject to a final investment decision, the facility is expected to be commissioned in 2024.
