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.
During the recent 2024 Ammonia Energy Conference, we explored all the latest developments in ammonia-powered maritime propulsion. Engine makers reported strong progress ahead of deployment in 2026, the same year that large-scale vessels will hit the water. The panel explored early operations for the ammonia-powered A-Tug in Japan, as well as ancillary technology systems required for maritime ammonia engines, catalyst after-treatment systems for emission mitigation, and the potential for fuel additives to boost ammonia engine performance.
Backed by the German Federal Government, MAN Energy Solutions will lead a consortium building on previous work to design and test an ammonia-powered four-stroke engine for marine applications.
