MAN Energy Solutions has launched the 'AmmoniaMot 2' research project to develop a four-stroke, medium-speed, dual-fuel test engine for maritime applications that runs on ammonia. The project, supported by the German Federal Ministry for Economic Affairs and Climate Action, aims to reduce greenhouse gas emissions by 90-95% while meeting existing emission regulations. Building on the success of the previous AmmoniaMot project, the new initiative involves partners from industry and research institutes. The project is set to run for 3½ years and focuses on decarbonizing the maritime industry by utilizing ammonia as a carbon-free fuel in engines. MAN Energy Solutions emphasizes the importance of decarbonizing fuels to achieve sustainability in the maritime sector and highlights ammonia as an excellent candidate due to its carbon-free nature. The company sees the future application of ammonia-powered engines in newbuild cargo or special vessels and as auxiliary power generators for ammonia-powered two-stroke vessels. For passenger ships, methanol is currently the fuel of choice. Partner roles in the project include engine concept development, combustion simulation, injector prototyping, and safety module design for ammonia fuel systems. Ammonia is recognized as a significant carbon-free fuel that will contribute to the decarbonization of the maritime industry, paving the way for a greener future.
