Yanmar Power Technology Co. Ltd, a subsidiary of Yanmar Holdings Co., Ltd., has embarked on the development of a hydrogen-fuelled 4-stroke high-speed engine for power generation for coastal vessels in Japan as part of the Nippon Foundation’s zero emission ship demonstration experiment.
The engine utilises hydrogen as a fuel, emitting no CO2 during combustion.
In parallel with the hydrogen engine development, YPT will also work on the creation of a hydrogen engine-compatible hybrid electric propulsion vessel, combining hydrogen engine generators with batteries. This innovative vessel design incorporates a container unit-type hydrogen power generation system on its upper deck. Uyeno TransTech Co., Ltd., a shipping company in the Uyeno Group, will be responsible for the vessel’s development and construction.
To support the transition towards zero emissions in maritime operations, YPT aims to develop a pilot ignition engine that utilises a small amount of pilot biofuel and hydrogen co-combustion, as well as a spark ignition hydrogen-only engine.
