In Xiamen Haicang Lingang International Logistics Park in Fujian province, a heavy-duty electric truck slowly pulls into an automated swapping station. Through precise mechanical maneuvers, the vehicle's depleted battery is seamlessly removed and replaced with a fully charged one. In less than five minutes, the truck is back on the road, continuing its container transport route while spewing zero emissions.

This highly efficient scene is powered by COSCO Shipping Investment (Xiamen) Supply Chain Development Co's green energy charging and swapping integrated operation project.

With a total investment of some 33 million yuan ($4.86 million), the initiative builds upon the foundation of green warehousing to establish a zero-carbon park. It aims to create the largest green energy production, storage and consumption integration demonstration base of any maritime port area nationwide.

The project encompasses three major sectors: electric heavy-duty trucks, charging and swapping stations, and photovoltaic power generation systems. The facility spans 16,000 square meters and boasts a total power capacity of 12,800 kilowatts, designed to handle 30 million kilowatt-hours of charging and swapping annually.
