In this Technology Insights article, we explore the different technology options for low-emission ammonia production from gas feedstock. What are the different energy, carbon capture, scale and maturity trade-offs that need to be considered? What technology choices are project developers currently making?
Wärtsilä has been contracted to supply the total technology package for the conversion of the Viking Energy to run on ammonia fuel. The original plan to retrofit the vessel with a 2 MW solid oxide fuel cell system was delayed by supply chain and development challenges, but SOFC developer Alma Clean Power will continue to test and scale its direct ammonia-fed technology for maritime applications.
Alma Clean Power is in the process of testing a modular, 100 kW, direct ammonia-to-electricity solid oxide fuel cell that will be able to be stacked to create larger power systems for maritime applications.
A new Scandinavian collaboration aims to transform Risavika and the wider Stavanger region as a bunkering hub for ammonia fuel, supplied by Iverson eFuels’ hydro-ammonia production project in Sauda.
The Norwegian Maritime Authority has approved the ammonia fuel system design to be deployed onboard the platform supply vessel Viking Energy. The system will directly feed 2 MW of solid oxide fuel cells, allowing for long-range, high power sailing of up to 3,000 hours per year.
New funding from the Norwegian government will assist two maritime ammonia developers: Amon Gas and Höegh Autoliners. Amon has confirmed orders for two ammonia-powered, mid-sized gas carriers, while Höegh will establish an ammonia fuel supply chain to ensure its Aurora Class car carriers can run on ammonia fuel on delivery in 2027.
Yara’s newly commissioned plant at Herøya Industrial Park will produce 10 tons per day of renewable hydrogen, enabling the production of 20,000 tons of renewable ammonia per year.
WinGD’s X‑DF‑A dual-fuel engines have been ordered by Singapore-based shipping giant AET for deployment onboard new Aframax tankers, being built in China. Fishing vessels operators Vardin and Framherji have ordered Wärtsilä 25 engines for a series of three fishing trawlers that will operate in the Faroe Islands. In construction news, CMB.TECH will build the Yara Eyde vessel for Yara and North Sea Container Line in China, with vessel delivery scheduled for mid-2026.
H2Carrier intends to develop two wind farms in far northern Norway with a combined capacity of 1.55 GW, which will power offshore hydrogen and ammonia production.
The European Hydrogen Bank has awarded nearly €720 million to seven renewable hydrogen and ammonia projects. The funding will act to bridge the price gap between the cost of hydrogen production and the price buyers are willing to pay. Recipients will receive €0.37 - €0.48 in subsidies per kilogram of renewable hydrogen, and will collectively produce 1.58 million tons of renewable hydrogen over ten years. In conducting a transparent auction process, the European Commission has also provided vital insights into trends in demand for renewable hydrogen and ammonia.
