Japan’s first tugboat equipped with a hydrogen-powered internal combustion engine, TEN-OH, has been officially delivered.
Constructed by Tsuneishi Shipbuilding as part of the Nippon Foundation’s Zero Emission Ships Project, TEN-OH was delivered on October 15.
The newbuild is equipped with a BEH2YDRO high-output hydrogen dual-fueled engine and high-pressure hydrogen gas storage system with a large-capacity and supply system, provided by JPNH2YDRO — a joint venture between Tsuneishi Group and CMB.TECH.
The 38-meter-long tugboat is powered by twin 12-cylinder hydrogen-blended engines (4,400 horsepower class) and stores around 250kg of hydrogen in high-pressure tanks, which is expected to ensure operational performance equivalent to conventional fuel use, whilst enabling significant CO2 reductions.
Compared to conventional tugboats, TEN-OH is projected to reduce CO2 emissions by approximately 60%.
Okumura Sachio , Representative Director, President & Executive Officer of Tsuneishi Shipbuilding, commented on this milestone: “It is a great honour to deliver Japan’s first hydrogen dual-fuelled tugboat.
“ Across our domestic and overseas operations, we are developing vessels powered by next-generation fuels such as methanol and LNG . By building on the expertise gained through this project and leveraging the collective strength of the Group, we will continue to drive innovation and contribute to a more sustainable future for the maritime industry.”
