Yanmar Holdings Co. (YPT), a subsidiary of Japan’s Yanmar Holdings Co. Ltd., has announced that it is committed to developing a high-speed, four-stroke, hydrogen-powered marine engine. The internal combustion engine will be used to generate power for coastal vessels in Japan.
The move is part of the Nippon Foundation’s Clean Ship Demonstration Experiment, which is part of the Zero Emission Ships project. The plan aims to prioritize the development of hydrogen-powered ships with the goal of achieving carbon neutrality in the coastal shipping sector by 2050.
By pioneering this field, YPT could not only benefit economically by anticipating the growing demand for greener shipping solutions, but also actively contribute to reducing the carbon footprint of the maritime sector in general. Demonstration experiments would be essential to validate the feasibility and effectiveness of this technology under real-world operating conditions.

Engine and Vessel
According to the plans, YPT will be responsible for developing two types of engines for the vessel: a pilot-ignition engine, which will use a small amount of pilot biofuel with hydrogen co-combustion, and a spark-ignition engine powered solely by hydrogen. This approach provides the flexibility and options needed to adapt to different operating conditions and fuel usage preferences.
Along with the development of the hydrogen marine engine, YPT will also focus on creating a hybrid-electric propulsion vessel compatible with the hydrogen engine. This model will integrate hydrogen engine generators and batteries for efficient and versatile operation. The coastal vessel will feature a containerized unit-type hydrogen power generation system on its upper deck.
The vessel will be built and developed by Uyeno TransTech Co. Ltd, a shipping company owned by the Uyeno Group. This strategic partnership leverages the expertise and resources of both companies to complete the project effectively and efficiently.

Medium term plan
YPT plans to begin ground verification tests in 2024 using a six-cylinder hydrogen engine with pilot ignition, aiming to complete verification operations by 2026. At the same time, it will conduct ground control tests with a spark-ignition engine running solely on hydrogen. The ultimate goal is to achieve zero emissions for coastal vessels by 2030 by encouraging the adoption of hydrogen propulsion systems.
Although the applications are primarily intended for small commercial vessels for coastal shipping, they also reflect the engine manufacturer’s desire to explore new fuels. There is scope for longer term application for low horsepower engines and potential use in recreational boating, provided that shoreside supply infrastructure is developed to meet demand.
YPT’s initiative to develop hydrogen-powered ships and conduct demonstration experiments marks an important step in the adoption of cleaner and more sustainable technologies in the maritime sector, joining similar efforts in other sectors such as land transport, aviation, rail, energy production and construction. Hydrogen appears to be a promising alternative to fossil fuels in these sectors due to its ability to produce energy without generating greenhouse gas emissions, thus marking a step forward towards a more environmentally friendly economy. .
