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," 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.
With beginnings in Osaka, Japan, in 1912, Yanmar was the first ever to succeed in making a compact diesel engine of a practical size in 1933. A pioneer in diesel engine technology, Yanmar is a global innovator in a wide range of industrial equipment, from small and large engines, agricultural machinery and facilities, construction equipment, energy systems, marine, to machine tools, and components — Yanmar’s global business operations span seven domains.
The Uyeno group is comprised of 35 companies engaged in the transportation, storage and sales of petroleum and chemical products essential for industrial and civic life, as well as being engaged in ventures related to solar energy and marine environments.
Since its founding in 1962, The Nippon Foundation, Japan’s largest philanthropic foundation, funded by the proceeds of Japanese motorboat racing, has pursued activities in a wide range of fields including support for children and persons with disabilities, disaster relief, ocean affairs, and humanitarian aid across racial and national borders.
