Core Viewpoint - CATL is progressively building a comprehensive zero-carbon shipping solution, with significant projects in various maritime sectors, including luxury cruise ships and electric tugboats [1][2]. Group 1: Electric Vessels - The first pure electric passenger ship in China, "Yujian 77," has officially launched in Xiamen Bay, featuring CATL's battery system that ensures zero emissions and low noise for a high-quality tourism experience [3]. - The battery system on "Yujian 77" utilizes CTP technology and integrated CCS technology, achieving an energy density of over 140Wh/kg, with a total power capacity of 3918kWh, enabling a range of 100km [3][4]. - The operation of "Yujian 77" is expected to reduce fuel consumption by nearly 250 tons and cut CO2 emissions by over 400 tons annually, equivalent to planting over 20,000 trees [4]. Group 2: Hydrogen-Electric Tugboats - The first hydrogen-electric tugboat in China, "Hydrogen Tug 1," has been put into service at Qingdao Port, representing the largest horsepower and lithium battery capacity in the domestic market [5][6]. - "Hydrogen Tug 1" features a lithium battery capacity of 7838.88kWh, an energy density of 140Wh/kg, and a maximum output power of 5200kW, allowing for over 12 hours of operation at a speed of 9 knots [6]. - The introduction of "Hydrogen Tug 1" is projected to reduce CO2 emissions by 1500 tons annually, contributing significantly to the establishment of a zero-carbon port in Qingdao [7].
