Yanmar tests first 70 MPa hydrogen refuelling
The test boat cruised on a route around the island of the Osaka-Kansai World Exposition 2025 and famous tourist spots on the city’s coast. The 70MPa high-pressure refuelling resulted in more than three times longer cruising time compared to the previous refuelling process.
The 70 MPa high-pressure hydrogen refuelling was carried out in cooperation with Toyota Tsusho Corporation, using a specially licensed high-pressure facility and a newly developed prototype long hydrogen refuelling hose.
The results will be used for the market deployment of hydrogen fuel cell systems as well as the study of hydrogen refuelling infrastructure for ships. Yanmar aims to obtain a type approval from classification societies so that the system can be installed in various types of ships to meet a planned launch to market in 2023.

YPT is developing a 300kW-class maritime fuel cell system incorporating fuel cell modules supplied by Toyota Motor Corporation, addressing the potential customer demands such as ones relating to the Carbon-Neutral Port concept of the Ministry of Land, Infrastructure, Transport and Tourism.
