Mitsubishi Shipbuilding has shipped two critical marine fuel system elements to Japan Engine Corporation for integration with J-ENG’s two-stroke ammonia engine, which passed a rigorous testing regime late last year. The engines will power NYK’s ammonia-fueled medium gas carrier vessels, with the first scheduled to enter service later this year.
Engine testing approval clears another hurdle for the vessels to hit the water and enter commercial service, with EXMAR planning sea trials “in the coming months”.
Kevin Rouwenhorst reports back from the 7th CFAA International Symposium in Tokyo, plus significant progress on the ground for Idemitsu Kosan, NYK Line, Resonac, and IHI Corporation.
GreenH has taken a final investment decision on its Slagen renewable ammonia project, plus two other electrolytic hydrogen projects on Norway’s coast. Nel ASA has been chosen to supply electrolyser technologies for Slagen and a series of electrolytic hydrogen projects in Norway, and will add a 1 GW production line for its new “Next Generation Pressurized Alkaline system” at its factory in Herøya.
Great Oceans Green Ammonia is Sri Lanka’s “pioneering” renewable ammonia and methanol developer. 4 GW of offshore wind, onshore solar and battery storage will not only help decarbonise Sri Lanka’s power sector, but produce methanol and ammonia fuel: 500,000 tons per year by 2030. Sri Lanka sits directly on the primary east-west shipping corridor connecting Southeast Asia, the Middle East, Europe, and East Africa.
Beginning in Rotterdam, the newly-opened route visits Oslo, Brevik, and Bremerhaven to deliver fertilizer weekly, and will be serviced by the ammonia-powered Yara Eyde from later this year.
Meet EXMAR and Lloyd’s Register, two marine first-movers preparing for the use of ammonia as a marine fuel. Learn about EXMAR’s ammonia-fueled gas carriers due for delivery this year, and a partnership with Lloyd’s Register to develop guidelines for the safe use of ammonia cargo as fuel.
Provided robust safeguards are in place, ammonia ship-to-ship transfers are technically and operationally feasible at Raffles Reserve Anchorage in Singapore. Combined HAZID and HAZOP analyses identified zero high-level risks and eleven medium-level risks, and the report includes a series of detailed operational recommendations for the first pilot ammonia StS transfer in Singapore port.
Wärtsilä will provide its four-stroke, ammonia-powered engine to Skarv Shipping Solutions for deployment on a new timber transport vessel to be built in China. Delivery of the full equipment set – including fuel gas supply system, release mitigation system, and a selective catalytic reduction system for exhaust treatment – is anticipated in late 2026.
The trio plan to build on a series of already successful collaborations between CF Industries and Trafigura, and push forward bunkering logistics planning for marine ammonia fuel on the US Gulf Coast and northwest Europe.
