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.
NYK has announced that the tugboat Sakigake has been completed, and will enter three months of commercial trials in Yokohama harbor and Tokyo Bay. Thanks to retrofits, Japan’s first LNG-fueled vessel has now become Japan’s first ammonia-fueled vessel.
An NYK-led consortium has been granted engine room safety accreditation by ClassNK for its ammonia-fueled, medium gas carrier design. The vessel is due to hit the water in 2026. Starting later this decade, NYK has also committed to transport renewable ammonia from Sembcorp’s under-development production project in India to Kyushu, Japan.
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 FuelEU Maritime Regulation is set to launch on August 31, requiring companies to submit monitoring plans ahead of its full implementation in January 2025. With modest initial targets and sophisticated compliance mechanisms like banking, borrowing, and pooling, the scheme offers flexibility while driving innovation in sustainable maritime technologies. The scheme also offers extra incentives for companies to proactively embrace Renewable Fuels of Non-Biological Origin (RFNBOs), before mandates enter into force next decade.
The pair will explore the integration of Amogy’s ammonia cracking technology with Yanmar’s under-development hydrogen internal combustion engine. Yanmar is a leading provider of marine engines for small-scale marine propulsion, and has also commercialised a hydrogen fuel cell system.
Moored in Yokohama Port, the A-Tug was refueled from a shoreside tanker truck with ammonia earlier this month. The ammonia for the demonstration was supplied by Resonac Corporation, and ammonia fuel is to be supplied by JERA once the vessel is delivered for commercial operations in the coming months.
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.
At last month’s MariNH3 conference in Nottingham, a series of keynotes laid out the opportunities and challenges ahead for marine ammonia fuel. Onboard ammonia cracking technologies are moving through testing phases and closer to commercialisation, vessel designers are working through the unique challenges of carrying ammonia fuel onboard, and emissions mitigation technology (in combination with adherence to existing Tier 3 standards) will be necessary to ensure that ammonia-powered vessels are more environmentally-friendly than conventional counterparts.
