Yanmar conducts world’s first 70 MPa high-pressure ship refueling with hydrogen
Yanmar Power Technology has completed a 70MPa high-pressure hydrogen refuelling of a ship – and the company believes it to be a world first.

The Yanmar Holdings subsidiary last week (Oct 20) confirmed the refuelling which featured a demonstration test boat, equipped with a hydrogen fuel cell system.
Once refuelled, the boat then ran a route around the planned island for the Osaka-Kanasai World 2025 and famous tourist spots on the coast of Osaka, Japan.
Refuelling of the ship was carried out in collaboration with Toyota Tshuo Corporation and used a specially licensed high-pressure facility and newly developed refuelling hose.
The 70MPa refuelling resulted in a more than three times longer cruising time, compared to the previously used refuelling method for the ship.
