Yanmar performs first high-pressure hydrogen refuelling
Yanmar Power Technology (YPT), part of the Yanmar Holdings group, reports it has conducted the world’s first 70 MPa high-pressure hydrogen refuelling of a ship using a demonstration test boat equipped with a hydrogen fuel cell system. The test boat cruised on a route around the island of the Osaka-Kansai World Exposition 2025 and popular tourist spots on the city’s coast.
The high-pressure refuelling was carried out in cooperation with Toyota Tsusho Corporation, using a specially licensed high-pressure facility and a newly developed prototype refuelling hose.
According to Yanmar, it resulted in more than three times longer cruising time compared to the previous refuelling process. The findings will be used in the deployment of hydrogen fuel cell systems as well as in the study of hydrogen refuelling infrastructure for ships.
YPT is developing a 300kW-class maritime fuel cell system incorporating fuel cell modules supplied by Toyota Motor Corporation. Yanmar aims to obtain a type approval from classification societies so that the system can be installed in various types of ships with global customers towards a planned launch to market in 2023.
