Where Green Ammonia Fits Germany’s Future
The Main Route: Imports and Ports
Germany expects future demand for hydrogen and hydrogen derivatives to exceed domestic production capacity. The federal government’s import strategy estimates that by 2030, around 50–70% of Germany’s hydrogen-product demand, or 45–90 TWh, may need to be imported. These imports may include hydrogen itself as well as derivatives such as ammonia, methanol and synthetic fuels.
This makes imported green ammonia a practical option. Ammonia can be shipped more easily than gaseous hydrogen and handled through port infrastructure that can be upgraded for low-carbon energy carriers. For Germany, ports such as Wilhelmshaven, Brunsbüttel and Hamburg are expected to play an important role in connecting global hydrogen derivative supply with domestic industrial demand.
Ammonia Cracking and Hydrogen Networks
One of Germany’s most important development paths is ammonia cracking. In this route, ammonia is imported to a coastal terminal, stored, cracked back into hydrogen and then supplied to industrial users.
Uniper’s Green Wilhelmshaven project illustrates this logic. The European PCI project fiche describes an ammonia reception facility capable of importing up to 2.6 million tonnes per year of renewable, green or blue ammonia. The project includes ammonia storage, rail loading and a large-scale ammonia cracking plant. Up to 20% of the ammonia could be redistributed directly by rail, while the larger share would be cracked into up to 0.28 million tonnes of hydrogen per year.
This model fits Germany’s hydrogen infrastructure plan. The approved hydrogen core network will have a total length of 9,040 km, with around 60% converted from existing natural gas pipelines. Investment costs are estimated at €18.9 billion, and the network is designed to connect major hydrogen production, storage, import and consumption regions by 2032.
Direct Use of Green Ammonia
Not all imported ammonia will be cracked. Some green ammonia may be used directly in fertilisers, chemicals or potentially maritime fuel supply chains. Germany already has strong chemical, port and logistics infrastructure, which makes direct ammonia use relevant alongside cracking.
Market formation has already started. In the H2Global pilot auction, Fertiglobe was selected to supply renewable ammonia to European ports from 2027. The contracted supply could start at 19,500 tonnes in 2027 and rise to a cumulative 397,000 tonnes by 2033, depending on production and supply conditions.
Where Modular Green Ammonia Can Fit
Small-scale local green hydrogen-to-ammonia-to-fertiliser projects are not the mainstream route in Germany today. The dominant direction is more likely to be ports, imports, ammonia cracking, hydrogen pipelines and large industrial users. However, this does not mean modular green ammonia systems have no opportunity.
For a company such as KAPSOM, the opportunity is to complement Germany’s large-scale pathway. Modular green ammonia units can support industrial demonstration projects, local renewable energy utilisation, green fertiliser pilots and decentralised ammonia production where local demand exists.
A skid-mounted green ammonia system can help industrial parks or regional energy projects test the integration of electrolysers, nitrogen supply, ammonia synthesis and intelligent operation at manageable scale. It can also serve users that want to start with a realistic capacity, validate performance and expand later.
Germany’s green ammonia market will most likely be led by infrastructure-scale projects. But within that wider system, modular green ammonia can still play a useful role: not as the dominant pathway, but as a flexible, local and scalable solution for selected industrial, agricultural and demonstration applications.
