On June 26, 2025, the "QING DIAN TUO 1" – the world's first high-power hydrogen-electric hybrid ASD Tugboat independently developed, designed, and built by our company – was successfully delivered to Qingdao Port of Shandong. This milestone marks a historic leap in the application of hydrogen energy in China's marine vessels, offering a shining "Chinese solution" for the global shipping industry's low-carbon transformation.

        As a "green pioneer" in marine equipment, the "QING DIAN TUO 1" integrates cutting-edge technology and superior performance. It achieves a calm-water speed of 14.2 knots during silent navigation, and its robust towing force of 82 tons has earned it the title of "Marine Hercules." The innovative "hydrogen fuel cell + liquid-cooled lithium battery" hybrid system acts as a "green heart" for the vessel, enabling true zero-carbon emissions and projecting an annual reduction of 1,500 tons of carbon dioxide.

        Leading the way, the "QING DIAN TUO 1" has filled multiple domestic technological gaps with its "black technologies": from being China's first hydrogen-powered port tug to boasting the largest horsepower and lithium battery capacity among port tugs; from featuring the industry's first fully automatic plug-and-play shore-based charging device to being the first Chinese electric propulsion vessel awarded the AUT-0 notation, it has set numerous "national firsts," engraving the glory of Chinese "intelligent" manufacturing on the vast ocean. Its successful commissioning holds landmark significance for the construction of China's smart and green ports.
