Yanmar Conducts World’s First 70 MPa High-Pressure Ship Refueling with Hydrogen
Yanmar Power Technology (YPT), a Group company of Yanmar Holdings Co., Ltd., has conducted the world’s first 70 MPa high-pressure hydrogen refueling 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 famous tourist spots on the city’s coast.

High-pressure facility
The 70 MPa high-pressure hydrogen refueling was carried out in cooperation with Toyota Tsusho Corporation, using a specially licensed high-pressure facility and a newly developed prototype long hydrogen refueling hose. The 70MPa high-pressure refueling resulted in more than three times longer cruising time compared to the previous refueling process. The results will be utilized for the market deployment of hydrogen fuel cell systems as well as the study of hydrogen refueling infrastructure for ships.
