The collaboration integrates MAN’s dual-fuel engine technology with COSCO Shipping Heavy Industry's repair and vessel modification capabilities.
Over the course of the demonstration, NYK analyzed the emission reductions achieved, with a peak of 94.4% reductions using 94.8% ammonia fuel under 75% engine load (similar results at 100% engine load).
Between 2026 and 2029, Mitsui O.S.K Lines will add three ammonia-powered Capesize bulkers and six chemical tankers to its fleet through joint ownership and chartership with CMB.TECH. MOL, Namura Shipbuilding and Mitsubishi Shipbuilding have also received AiP from ClassNK for a large-size ammonia-powered ammonia carrier.
Alfa Laval has signed its first contract for its new ammonia fuel supply system, FCM Ammonia. The system will be installed onboard seven LPG/ammonia carriers being built in China, each featuring WinGD’s X-DF-A engine.
With commercial deployment scheduled to start this June, both WinGD and MAN ES’s under-development ammonia fueled engines have reported promising results across performance, ammonia safety and emissions optimisation parameters. MAN ES and MITSUI have also commenced a commercial-scale prototype test of the MITSUI-MAN ES large-bore, low-speed, two-stroke ammonia engine in Tamano, Japan.
In 2025, the pieces are rapidly assembling to enable and accelerate imports of ammonia energy to Japan. This year, government agency METI is due to announce two lots of key funding, including contracts for difference subsidies and development of import infrastructure. Power generation technologies will be commercialised within the next few years, and more maritime players are joining the push to deploy ammonia fuel in Japanese ships.
The trio has developed a high-pressure, small-scale, direct liquid injection engine utilising pure ammonia fuel with no additives or pilot fuel. Last June the Korea Institute of Machinery and Materials unveiled a MW-scale, LNG-ammonia co-fired engine for maritime applications, utilising the same combustion approach.
In Japan, the Ministry of Land, Infrastructure, Transport and Tourism, in cooperation with the Ministry of the Environment will invest $212 million in the domestic manufacture of ammonia engines, fuel tanks and components. In Korea, the national Export-Import Bank has committed to supporting ammonia-fueled newbuilds.
WinGD has received orders for its 52-bore X-DF-A ammonia-fuelled engines for seven LPG/ammonia dual-fuel carriers. Germany’s Hapag-Lloyd has ordered 24 modern vessels from Chinese shipyards, among them 12 ammonia-ready newbuilds.
Japan Engine Corporation (J-ENG) announced that it has completed test operations on its low-speed, 2-stroke engine, with installation and subsequent trial operations due to begin in April 2025. Installation will be onboard one of the first ammonia-fueled vessels to hit the water: the NYK-led midsized gas carrier project.
