World’s Largest Fully Electric Container Ship “Ningyuan Dian Kun” Delivered and Commences Service

On April 15, 2026, China marked a major milestone in maritime innovation with the official delivery of the “Ningyuan Dian Kun” — the world’s largest fully electric intelligent container ship.

Designed and developed under the leadership of China State Shipbuilding Corporation, the Ningyuan Dian Kun has successfully completed all sea trials and was formally delivered to its operator before setting sail from Ningbo‑Zhoushan Port to Zhapu Port on its maiden commercial voyage.

With a length of 127.8 meters, a beam of 21.6 meters, and a cargo capacity of 742 TEU, the vessel represents a significant leap forward for battery‑powered maritime transport. Unlike traditional containerships powered by fossil fuels, the Ningyuan Dian Kun is driven entirely by electricity through a system of 10 containerised battery modules with a total capacity of around 19.6 megawatt‑hours, powering dual permanent‑magnet propulsion motors.

The ship’s zero‑emission design enables zero carbon, zero noise, and zero pollution operations throughout its voyage, a breakthrough in coastal container shipping. It is expected to reduce carbon dioxide emissions by over 1,400 tonnes per year compared with conventional vessels.

In addition to its clean propulsion system, the vessel integrates advanced intelligent systems for energy management, navigation, and ship‑to‑shore connectivity, enabling higher operational efficiency and greater automation. These technologies reflect China’s growing capabilities in green shipping and maritime digitalisation.

The Ningyuan Dian Kun will operate on the Ningbo–Zhapu coastal feeder route, playing a key role in short‑sea logistics while serving as a benchmark for zero‑emission shipping solutions worldwide.

This delivery not only showcases innovation in electric maritime propulsion but also underscores a broader industry shift toward sustainability, cleaner energy use, and smarter shipping operations — themes that are increasingly important for global supply chains and environmental goals.
