Tsuneishi Shipbuilding in Japan recently unveiled the country's first hydrogen-fuel tugboat, marking a significant step towards sustainable practices in the maritime industry. The tugboat, equipped with a high-power output hydrogen dual-fuel internal combustion engine (ICE) and a large-capacity hydrogen gas storage system, aims to reduce carbon dioxide emissions by approximately 60% compared to conventional tugboats that use traditional marine fuels. The vessel is designed with twin 12-cylinder hydrogen-blended engines, totaling 4,400 horsepower, and can operate using a combination of hydrogen and traditional marine fuels to maintain performance standards. With facilities to store around 250kg of high-pressure hydrogen gas, the tugboat ensures operational efficiency while utilizing hydrogen fuel. Moreover, the tugboat incorporates safety measures by allowing the vessel to switch to traditional marine fuels in case of any hydrogen fuel system malfunction, ensuring the same level of safety as traditional vessels. Mr. Nishijima Takanori, General Manager of the Design Division at Tsuneishi Shipbuilding, highlighted the company's commitment to carbon neutrality by developing and constructing new fuel vessels, including methanol-fueled, LNG-fueled, and hydrogen-fueled vessels. This initiative signifies a strategic move towards innovative and sustainable practices in the maritime sector, promoting the use of green technologies like hydrogen-powered engines to reduce environmental impact and drive the industry towards a cleaner future.
