The maritime world is watching as China pushes the boundaries of zero-emission technology. On February 1, 2026, the Ningyuan Diankun, the world’s first 10,000-ton all electric containership, departed from its dock in Jiangxi province to begin rigorous sea trials.
This vessel isn’t just a prototype; it’s a statement of intent from Chinese shipyards aiming to dominate the green short-sea and feeder markets.
A Technical Marvel: Powering a 10,000-Ton Giant
Built by Jiangxi Jiangxin Shipbuilding, the Ningyuan Diankun represents a massive scale-up from previous electric vessel experiments. While electric propulsion has typically been reserved for small ferries or inland barges, this ship is designed for the high-demand environment of coastal feeder routes.
Key Specifications of the Ningyuan Diankun
The vessel utilizes a modular approach to energy, allowing for rapid turnaround times that rival traditional fueling.
| Feature | Specification |
| Length Overall (LOA) | 127.8 meters |
| Beam / Depth | 21.6 meters / 10.5 meters |
| Capacity | 740 TEU |
| Battery System | 10 containerized units (19,000 kWh total) |
| Propulsion | 2 x 875 kW permanent magnet motors |
| Maximum Speed | 11.5 knots |
The ship’s energy management is enhanced by a photovoltaic system installed on deck, providing renewable auxiliary power for onboard systems. Perhaps most importantly, the ship supports battery swapping. Instead of waiting hours to recharge, the containerized battery units can be lifted and replaced at the terminal, keeping the vessel on schedule.
Intelligence on the High Seas: Autonomous Capabilities
The 2026 sea trials, currently taking place off the coast of Shanghai, are testing more than just the battery life. The Ningyuan Diankun is equipped with an intelligent control platform and an autonomous navigation suite.+1
- Autonomous Mode: The ship is capable of route planning and autonomous sailing in open waters.
- Smart Engine Room: Real-time monitoring of the electric drivetrain ensures peak efficiency and predictive maintenance.
- Collision Avoidance: All-weather visual perception systems allow the ship to detect and navigate around obstacles without human intervention.
These “smart” features are essential for shipping companies looking to reduce operational costs and human error in busy coastal corridors.
Strategic Impact on Green Shipping
Upon successful completion of its trials, the Ningyuan Diankun will be delivered to Ningbo Ocean Shipping Co., Ltd. It is the first of two sister ships (the second being the Ning Yuan Dian Peng) destined to serve the Ningbo-Zhoushan port.+1
This project is a cornerstone of China’s “Green and Low-Carbon Advanced Technology Demonstration,” providing a blueprint for sustainable practices for green shipping. By replacing heavy fuel oil with electricity in the feeder sector, China is effectively tackling the emissions of the “last mile” in global trade.
“The Ningyuan Diankun is the ‘Tesla of the Seas.’ It proves that battery power is no longer limited to the river—it’s ready for the ocean.” — Industry Analyst, Feb 2026.
As classification societies prepare to certify this new class of vessel, the industry must now ask: how quickly can shore-side infrastructure keep up with this electric revolution?
