China's first hydrogen-electric tugboat, named 'Hydrogen Electric Tug No. 1,' has been launched at Qingdao Port in Shandong, marking a significant milestone in the country's green port operations. Developed with the support of CATL, the vessel features the largest lithium battery capacity among its counterparts, enabling true zero-carbon emissions. Tugboats are crucial for port logistics, and as ports globally aim for low-carbon operations, battery-powered tugboats like this one are becoming essential in driving the transition. Equipped with a high-performance battery system developed by CATL, the tugboat can operate for over 12 hours at a cruising speed of 9 knots, with a peak output of 5,200 kW and a maximum bollard pull of 82 tonnes, showcasing exceptional performance in marine conditions. The tug is anticipated to reduce carbon dioxide emissions by 1,500 tonnes annually, supporting Qingdao Port's ambition of becoming a zero-carbon facility. CATL's dedication to marine decarbonization is evident through its expanding portfolio of zero-carbon marine solutions, which includes various eco-friendly vessels like hybrid catamarans and fully electric cruise ships, contributing to sustainability in the maritime industry.
