Wedoany.com Report-Oct. 17, Japan’s first tugboat powered by a hydrogen internal combustion engine, named TEN-OH, was delivered on October 15 in a significant step toward sustainable maritime operations. Built by Tsuneishi Shipbuilding as part of the Nippon Foundation’s Zero Emission Ships Project, the vessel introduces advanced technology to reduce carbon emissions in the shipping industry.

The 38-meter tugboat features a BEH2YDRO high-output hydrogen dual-fueled engine and a high-pressure hydrogen gas storage system, developed by JPNH2YDRO, a joint venture between Tsuneishi Group and CMB.TECH. Equipped with twin 12-cylinder engines delivering 4,400 horsepower, TEN-OH stores approximately 250kg of hydrogen in high-pressure tanks. This setup ensures performance comparable to traditional fuel-powered tugboats while significantly lowering environmental impact.

TEN-OH is expected to reduce CO2 emissions by about 60% compared to conventional tugboats, offering a cleaner alternative for maritime operations. The vessel’s design supports Japan’s efforts to integrate next-generation fuels into its shipping sector, aligning with global sustainability goals.

“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,” said Okumura Sachio, Representative Director, President & Executive Officer of Tsuneishi Shipbuilding.

The delivery of TEN-OH marks a milestone in advancing eco-friendly maritime technology, with Tsuneishi Shipbuilding leveraging its expertise to support the transition to low-emission vessels. The project highlights collaborative efforts to enhance sustainability in Japan’s shipping industry, paving the way for broader adoption of hydrogen and other alternative fuels.
