MAN Energy Solutions has started the ‘AmmoniaMot’ project. In this project, partners from industry and research institutes, aim to produce a dual-fuel, medium-speed engine capable of running on diesel-fuel and ammonia.
Due to run for three years from December 2020, project partners include the University of Munich, Neptun Ship Design, WTZ and Woodward L’Orange.
More specifically, the University of Munich (TUM) will employ a rapid-compression expansion machine to establish the fundamentals concerning the combustion of ammonia and will develop the combustion models necesary for fast adaption of the technology to different engine sizes.
Additionally, WTZ will use a high-speed test engine to develop a combustion concept for the new engine. This will form the basis for defining any requirements for exhaust-gas aftertreatment.
Moreover, Woodward L’Orange will produce the injection system for the ammonia tests at TUM and WTZ. The technology will be scaled up to large, four-stroke engines in the project.
There is little doubt but that ammonia will become an important carbon-free energy carrier and thus will contribute to decarbonising the maritime sector. The AmmoniaMot project will deliver the base for future, commercial, four-stroke engines, which will be key in legitimising ammonia as a fuel and furthering the maritime energy transition
Christian Kunkel, Head of Combustion Development, Four-Stroke R&D, MAN Energy Solutions, said.
MAN Energy Solutions Two-Stroke Business has already announced that it will deliver ammonia-fuelled engines by 2024.
