Core Viewpoint - The article highlights the successful trial of China's first hydrogen-electric dual-energy hybrid tugboat "Hydrogen Electric Tug 1," which is expected to significantly reduce carbon emissions in port operations [3][5]. Group 1: Tugboat Features and Innovations - The "Hydrogen Electric Tug 1" is equipped with an innovative hybrid system combining hydrogen fuel cells and liquid-cooled lithium batteries, achieving true zero carbon emissions [5]. - The tugboat has the largest horsepower and lithium battery capacity among port operation tugs in China, and it has received the AUT-0 additional mark for electric propulsion vessels [5]. - It is estimated that the tugboat will reduce carbon dioxide emissions by over 1,500 tons annually once it is in operation [5]. Group 2: Technical Developments - The tugboat features a maximum towing force of 82 tons and a range of 120 nautical miles, supported by a hydrogen storage and supply system developed by a specialized technical team [7]. - Advanced marine "three-proof" technology has been developed to enhance the hydrogen storage system's performance under extreme environmental conditions [7]. Group 3: Hydrogen Refueling Solutions - A specialized hydrogen refueling system has been created to address the challenges of hydrogen refueling for ships, successfully completing the first shore-based hydrogen refueling operation for the "Hydrogen Electric Tug 1" [9]. - The project demonstrates the leading technology application by the technical team in the upstream and downstream fields of hydrogen energy shipping [9][10].
