MAN Energy Solutions has announced the launch of the “AmmoniaMot 2” research project, marking another significant milestone in its pursuit of ammonia as a sustainable marine fuel. Following the successful design and testing of the world’s first two-stroke ammonia engine, MAN is now focusing on a four-stroke, medium-speed, dual-fuel test engine powered by ammonia.

The project, initiated in August 2024, is supported by the German Federal Ministry for Economic Affairs and Climate Action (BMWK) and will run for 3½ years. It builds on the achievements of the initial “AmmoniaMot” project, which concluded in May 2024 after conducting essential research into ammonia combustion in internal combustion engines. MAN Energy Solutions is again leading the project, working alongside a mix of partners from the original project, such as WTZ Roßlau, Woodward L’Orange, and the Universities of Munich and Rostock, as well as new collaborators, including Neptun Ship Design, GenSys and MNR.

Alexander Knafl, head of engineering R&D Four-Stroke at MAN Energy Solutions, commented: “This project is the logical next step after AmmoniaMot, aligning perfectly with our strategy to develop sustainable technologies. We are excited to work again with our esteemed partners. Decarbonising the maritime industry starts with decarbonising fuels, and ammonia is a key candidate for this, being carbon-free and eliminating CO2 emissions when used in our engines.”
