Green Ammonia’s Two European Roles
France: From Low-Carbon Power to Fertiliser
France’s opportunity begins with its electricity system. In 2025, mainland France generated 547.5 TWh of electricity, with low-carbon sources accounting for more than 95% of production. This gives France a strong base for renewable and low-carbon hydrogen, especially where hydrogen can be used directly in existing industrial processes.
For ammonia, the most practical early pathway is fertiliser decarbonisation. Conventional ammonia production depends on hydrogen, which is usually produced from natural gas. Replacing part of that fossil-based hydrogen with electrolytic hydrogen can reduce the carbon footprint of ammonia and downstream nitrogen fertilisers.
The ABC Ottmarsheim project illustrates this route. Hynamics states that the project will use a 50 MW electrolyser to produce 6,600 tonnes of renewable and low-carbon hydrogen per year. This hydrogen will support annual production of 36,000 tonnes of carbon-free ammonia and avoid more than 46,000 tonnes of CO₂ emissions each year. The project also received approval for €144 million in French state aid.
Germany: Imports, Ports and Ammonia Cracking
Germany’s green ammonia logic is different. Germany has a rapidly growing renewable power sector, but it also expects future hydrogen demand to exceed domestic production. The German government’s import strategy estimates that by 2030, 50–70% of Germany’s hydrogen-product demand, or 45–90 TWh, may need to be imported. These imports may include hydrogen and derivatives such as ammonia, methanol and synthetic fuels.
This makes ammonia a strategic hydrogen carrier for Germany. Ammonia is easier to ship than gaseous hydrogen, and Germany’s North Sea ports can become entry points for global hydrogen derivatives. Some ammonia may be used directly in fertilisers, chemicals or future marine fuel supply chains. But a major German pathway is to import ammonia and convert it back into hydrogen through ammonia cracking.
Uniper’s Wilhelmshaven project shows this clearly. A European PCI project fiche describes an ammonia import terminal capable of receiving up to 2.6 million tonnes per year of renewable, green or blue ammonia. The project includes storage, rail loading and a large-scale cracking plant that could convert most of the imported ammonia into up to 0.28 million tonnes of hydrogen per year.
Same Molecule, Different Market Logic
The same molecule therefore serves two different market roles. In France, green ammonia can be a local industrial product linked to fertiliser production and partial decarbonisation of existing sites. In Germany, green ammonia is more likely to act as an imported hydrogen derivative connected to ports, cracking assets and hydrogen pipelines.
This does not mean France will only produce ammonia locally, or Germany will only import it. Both markets will develop mixed pathways. However, their early priorities are different. France has a stronger near-term case for local green ammonia projects connected to existing fertiliser and industrial users. Germany has a stronger infrastructure case for imported ammonia, ammonia cracking and industrial hydrogen supply.
What This Means for Industry
For companies in the green ammonia sector, the lesson is clear: market entry strategies must match national conditions. A project model that works in France may not work in Germany without adjustment.
In France, project developers should focus on local low-carbon hydrogen, fertiliser decarbonisation, industrial clusters and agricultural value chains. In Germany, they should pay close attention to port infrastructure, ammonia import terminals, hydrogen pipelines, industrial users and cracking technology.
Green ammonia will be important in both countries. But its role will not be identical. France points toward green ammonia as a low-carbon industrial and fertiliser product. Germany points toward green ammonia as a traded hydrogen carrier that can be imported, stored, distributed and cracked. Understanding this difference is essential for any company seeking to enter Europe’s green hydrogen and green ammonia market.
