Nippon Yusen Kabushiki Kaisha (NYK), Yanmar Power Solutions Co., Ltd. (Yanmar Power Solutions), and ENEOS Corporation (ENEOS) have agreed to install a hydrogen fuel cell system for a new dining cruise ship scheduled to enter service in 2027. The vessel will succeed Lady Crystal, currently operated by the NYK Group in the Tennoz Isle area of Tokyo.

The hydrogen fuel cell system will be designed by Yanmar Power Solutions and integrated into the vessel using hydrogen storage modules provided by Toyota Motor Corporation as part of the fuel supply system.

In preparation for adoption, NYK conducted comprehensive verification in accordance with the safety guidelines for hydrogen fuel cell ships established by Japan's Ministry of Land, Infrastructure, Transport and Tourism (MLIT), confirming the system’s safety and reliability. By leveraging the combined expertise of Yanmar Power Solutions, NYK, and Toyota Motor Corporation, the project has realized the efficient integration of hydrogen-related equipment.

For this vessel, safety will be the highest priority. At the same time, careful attention will also be paid to creating a comfortable onboard environment befitting a dining cruise ship. The project aims to provide a high-quality cruise experience.

ENEOS, an energy infrastructure provider, will be responsible for hydrogen production at refueling stations — primarily located in Tokyo — and for supplying hydrogen to the storage modules. Drawing on its experience in developing and operating numerous hydrogen stations across Japan, ENEOS will work to ensure both safety and a stable supply.

By adopting a hydrogen fuel cell system for the vessel, the three companies aim to advance the practical use of hydrogen in the maritime sector and contribute to the decarbonization of the shipping industry.
