The first pure battery-powered container ship, the N997, developed by COSCO Shipping Heavy Industry (Yangzhou) Co., Ltd., a subsidiary of China COSCO SHIPPING Corporation Limited (COSCO SHIPPING Group), set sail in Yangzhou, East China's Jiangsu Province, on July 26.
The vessel is the first 700TEU river-sea pure battery-powered container ship independently designed, developed and built by China with full intellectual property rights.
As a key project, it aligns with COSCO SHIPPING Group's efforts to actively achieve the green, low-carbon and intelligent transformation of the shipping industry, and promote green and low-carbon development. It also helps advance the electrification of container ships on the main line of the Yangtze River, facilitate the green transformation of Yangtze River waterway transportation, and demonstrate green and zero-carbon shipping.

The N997 is the world's first large-scale pure battery-powered container ship for river-sea transport, and its battery capacity is the largest in the world.
At a length of 119.8 meters and a width of 23.6 meters, the ship achieves battery swapping and recharging through a box-type mobile power source. Battery power is used throughout its entire voyage and its preset battery capacity far exceeds that of existing ships, both domestically and internationally. It is leading in the world in terms of the number of containers, deadweight tons, and the battery capacity of pure battery container ships.
The intelligent ship system of the ship consists of an intelligent integration platform, intelligent navigation, intelligent engine room and the intelligent monitoring of the ship's energy efficiency.
Based on the actual needs of the shipowner, the ship can adjust to different speeds for various sections of the voyage, considering such factors as the ship's arrival time, water flow, and battery capacity.
A situational awareness system has been installed to provide early warnings and alarms for navigation and situational judgment in inland river environments. The smart engine room monitors the operating status of the box-type power pack and related devices. Smart energy efficiency reflects the box-type power supply and the energy efficiency analysis of the entire ship.
