Group 1: Technological Innovation - "Hydrogen Electric Tug 1" is the first hydrogen-powered tugboat in China, featuring a hybrid system that includes a hydrogen fuel cell and a liquid-cooled lithium battery, capable of outputting 7000 horsepower [1][2]. - The tugboat's lithium battery has a total capacity of 7838 kWh, allowing it to meet the demands of frequent starts and high-load operations in port environments [2]. - The tugboat can generate a towing force of 82 tons and has a maximum speed of 14.2 knots in still water, demonstrating its powerful performance [2]. Group 2: Environmental Impact - The "Hydrogen Electric Tug 1" is designed to produce zero carbon emissions, with an estimated reduction of approximately 1500 tons of CO2 emissions annually, equivalent to the carbon offset of over 1000 acres of afforestation [3]. - The tugboat's lightweight design minimizes its empty weight, contributing to reduced energy consumption during operations [3]. Group 3: Operational Efficiency - The tugboat features two operational modes: an economic mode for normal port tasks and a power mode for assisting large vessels in challenging conditions, allowing for flexibility based on operational needs [4]. - Compared to traditional fuel-powered tugboats, the "Hydrogen Electric Tug 1" operates with significantly lower noise and vibration levels, enhancing the working environment [4]. Group 4: Smart Navigation - The tugboat is equipped with a multifunctional integrated system based on Beidou technology, which replaces traditional navigation systems and enhances safety and operational efficiency through real-time data integration [6]. - The integration with the port's digital twin platform allows for optimized routing and collision warnings, marking a transition from "blind navigation" to "intelligent navigation" [6]. Group 5: Infrastructure Development - Qingdao Port is developing supporting infrastructure, including the first hydrogen refueling station at a port in China, to facilitate the operation of the "Hydrogen Electric Tug 1" and hydrogen-powered vehicles [6]. - The port has also created an automatic intelligent shore charging device, improving charging efficiency by over 200% during operational downtime [6].
