Using a demonstration test boat equipped with a hydrogen fuel cell, Yanmar Power Technology (YPT) has conducted the world’s first 70 MPa (over 10,000 psi) high-pressure hydrogen refueling of a vessel.
The refueling was carried out in cooperation with Toyota Tsusho Corporation, using a specially licensed high-pressure system and a newly developed prototype long hydrogen refueling hose.
YPT says the 70 MPa high-pressure refueling resulted in more than three times longer cruising time compared to the previous refueling process. The results of the test will be utilized in bringing hydrogen fuel cell systems to market and in studies of the hydrogen refueling infrastructure for ships.
YPT, a group company of Yanmar Holdings Co., Ltd, is developing a 300 kW class maritime fuel cell system incorporating fuel cell modules supplied by Toyota Motor Corporation/
Yanmar aims to obtain a type approval from classification societies enabling the system to be installed in various types of ships as a step towards a planned market launch in 2023.
