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”.
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.
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.
Anglo-Eastern announced that the first cohort has successfully completed its inaugural Pilot Training Course on Ammonia as a Marine Fuel. Already the ship manager for the ammonia-fueled vessel Fortescue Green Pioneer, Anglo-Eastern will soon take on that responsibility for a series of vessels coming out of Chinese shipyards, managing vessels for CMB.TECH.
Despite the successes and progress made in 2025, the year remains a missed opportunity for ammonia energy. The first complete supply chains for renewable ammonia are emerging, and some 600,000 tons of annual production capacity is set to be online in northeast China early next year. Maritime engines, cracking, and power & heat technology solutions also made their mark, moving from feasibility into deployment. But disappointing outcomes at the IMO and government support that failed to spark market development remains an issue, with plenty of critical, detail-heavy work ahead of us in 2026.
CMB.TECH has signed an off-take agreement for renewable ammonia produced by Energy China at its now-operational Songyuan project in Jilin Province, northeast China. CMB.TECH will also acquire a minority stake in Jiangsu Andefu (ADF) one of China's largest ammonia supply chain companies and China’s first exporter of liquid ammonia in 2011.
China-based FZU Zijin has unveiled two applications for its proprietary ammonia cracking technology: a newly-opened ammonia-to-hydrogen vehicle refueling station, and a coastal vessel powered by an internal combustion engine, fed with cracked ammonia fuel.
Everllence has launched its new dual-fuel ME-LGIA (Liquid Gas Injection Ammonia) engine at an industry event in Copenhagen, ahead of the first units being delivered next year.
The outcome leaves the global shipping industry with a target to achieve net-zero emissions by 2050, but – for now – no detailed pathway to reach those targets. The result also leaves a certainty gap, delaying critical investment in zero or near-zero (ZNZ) fuels and propulsion technologies. Despite the setback, work on finer details and mechanisms to be included in the framework continued this week in London.
