OSAKA, JAPAN, January 11, 2024 /EINPresswire.com/ — Yanmar Power Technology Co., Ltd. (YPT), a subsidiary of Yanmar Holdings Co., Ltd., has embarked on the development of a hydrogen-fueled 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 utilizes 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 utilizes a small amount of pilot biofuel and hydrogen co-combustion, as well as a spark ignition hydrogen-only engine. The company plans to commence onshore verification tests in 2024 using a 6-cylinder hydrogen engine with pilot ignition, with the goal of conducting verification operations by 2026. Concurrently, YPT will conduct onshore verification tests using the spark ignition hydrogen-only engine. By approximately 2030, they aim to achieve zero emissions for coastal vessels by promoting the adoption of hydrogen energy-based propulsion systems.

The Zero-Emission Ship Project

The “Zero-Emission Ship Project,” led by the Nippon Foundation, prioritizes the development of hydrogen-fueled ships to achieve carbon neutrality in the coastal shipping sector by 2050. Through this initiative, YPT aims to pioneer the development of hydrogen-powered vessels and conduct demonstration experiments.
