TSUNEISHI SHIPBUILDING Co., Ltd.has launched the Japan’s first tugboat in Japan to be equipped with a hydrogen-powered internal combustion engine . This vessel was launched at TSUNEISHI Factory. The vessel is equipped with a high-power output hydrogen dual-fuelled ICE and a high-pressure hydrogen gas storage system with large-capacity and supply. It also used “JGreeX” which are produced by JFE Steel Corporation as green steel for all of its steel plates. By utilising green steel and hydrogen fuel to reduce the environmental impact, we will provide cleaner vessels and contribute to decarbonisation.
This tugboat is installed with twin 12-cylinder hydrogen-blended engines (4,400 horsepower class), and by hydrogen in combination with traditional marine fuels, with the target of reducing carbon dioxide emissions by approximately 60% compared to conventional tugboats that use traditional marine fuels. Furthermore, by having facilities to store approximately 250kg of high-pressure hydrogen gas, it is possible to maintain the same operational performance as when using conventional fuel while also making use of hydrogen fuel. In the unlikely event of failure of the hydrogen fuel system, the vessel can operate with only traditional marine fuels, thus ensuring the same level of safety as conventional vessels.
In addition, “JGreeX“, which are used for all of the vessel’s hull, is a green steel material that has significantly reduced CO2 emissions by crediting the steel material with the amount of CO2 emissions reduced in the steel production process. With the use of “JGreeX”, it contributes to a 100% reduction in CO₂ emissions caused by steel plates.
