Yanmar power for Japanese hybrid passenger first

The 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.

Hanaria is Japan’s first hybrid passenger ship to use both hydrogen and biodiesel and represents a significant breakthrough in achieving carbon neutrality for the sector.

Innovative power

The vessel operates with an onboard electric propulsion system that powers the ship’s drive using generated electricity.

Yanmar PT took charge of the ship’s comprehensive power system design, incorporating two hydrogen fuel cells, batteries, biodiesel generators, power management system, propulsion equipment, remote monitoring and other elements.

In addition, when running solely on the hydrogen fuel cell system and batteries, the ship creates zero emissions, with notable reductions in power source vibrations and noise.

The 3000kg system comprises eight tanks with a combined power of 250kW, which allows a speed of 22 knots.

Yanmar’s fuel cell can be installed in work boats and passenger ships as well as cargo ships and is aimed at coastal areas where hydrogen refuelling is relatively accessible.
