Yanmar Hydrogen Engine Production Plan Approved Under Zero-Emission Ships Project

Yanmar Power Technology Co., Ltd., a subsidiary of Yanmar Holdings, has received approval for its “New Production Plan for Hydrogen-Fueled Engines and Hydrogen Fuel Cell Systems” under Japan’s Ministry of the Environment and Ministry of Land, Infrastructure, Transport and Tourism’s “Promotion of the construction of zero-emission ships etc.” The proposal was approved on January 9, 2025.

The project aims to establish an advanced production system for zero-emission ships powered by hydrogen and batteries. By developing essential production facilities for hydrogen-fueled propulsion systems, the initiative seeks to reduce CO2 emissions through market adoption while boosting industrial competitiveness and economic growth.

Yanmar Power Technology is actively working toward the YANMAR GREEN CHALLENGE 2050, a Group-wide initiative to achieve a sustainable society. In August 2023, the company introduced a hydrogen fuel cell system for marine use. Additionally, Yanmar has completed onshore tests of a pilot-ignition hydrogen 4-stroke high-speed engine for power generation in coastal vessels, achieving a rated output of approximately 500 kW.

With support from the Zero Emission Ship Construction Promotion Project, Yanmar plans to accelerate its hydrogen engine production targets from 2050 to 2040. The company also aims to achieve 100% carbon-neutral marine power products, including hydrogen engines, around 2045—exceeding the International Maritime Organization’s greenhouse gas reduction targets.

Yanmar Power Technology will continue to deliver eco-friendly solutions to help customers meet their decarbonization goals.
