Yanmar Power Technology (Yanmar PT), a subsidiary of Yanmar Holdings Co., Ltd, has made its first delivery of its newly commercialized maritime hydrogen fuel cell system, introduced in August 2023. This system was supplied to the passenger ship HANARIA, operated by MOTENA-Sea, a company backed by Mitsui O.S.K. Lines, Ltd. and other investors.

The HANARIA is Japan’s first hybrid passenger ship able to use both hydrogen and biodiesel. This vessel operates with an onboard electric propulsion system that powers the ship’s drive using generated electricity.
