Tsuneishi Delivers Japan’s First Hydrogen Dual-Fuel Tugboat

Tsuneishi Shipbuilding has delivered Ten-Oh, Japan’s first tugboat equipped with a hydrogen-powered internal combustion engine.

The 38-meter tugboat is equipped with a BeHydro high-output hydrogen dual-fuel engine and a high-pressure hydrogen gas storage system with large-capacity and supply system, supplied by JPNH2YDRO — a joint venture between Tsuneishi Group and CMB.TECH.

The vessel was developed and built under The Nippon Foundation’s Zero Emission Ships Project which aims to develop vessels with zero CO₂ emissions.

The newly delivered tugboat is powered by twin 12-cylinder hydrogen-blended engines (4,400 horsepower class) and stores around 250kg of hydrogen in high-pressure tanks. This ensures operational performance equivalent to conventional fuel use, whilst enabling significant CO2 reductions.

In the unlikely event of a hydrogen fuel system failure, the vessel can continue to operate solely on marine fuel, maintaining safety as the same standard as conventional vessels.
