Qingdao Port pioneers zero‑emission maritime operations with debut of hydrogen‑electric tugboat
On June 26, 2025, Qingdao Port in Shandong province formally commissioned China’s first hydrogen‑electric tugboat, Tug No. 1—a significant milestone in the maritime industry’s transition to clean energy. Developed by Jiangsu Zhenjiang Shipyard, the vessel integrates a hybrid propulsion system combining hydrogen fuel cells with liquid‑cooled lithium batteries, enabling emissions-free harbor operations.
Measuring approximately 39 metres in length, Tug No. 1 delivers a towing capacity of 82 tons, making it the most powerful harbor tug in China. It can sustain more than 12 hours of continuous operation at a service speed of 9 knots solely on battery power. The vessel also employs intelligent shore-based charging systems and Beijing’s Beidou navigation to support automated operations with enhanced efficiency and reduced noise.
Compared to conventional diesel-powered tugs, Tug No. 1 is expected to reduce carbon dioxide emissions by more than 1,500 tons annually. It also offers benefits in terms of lower noise, longer equipment lifespan, and higher energy efficiency.
The introduction of this hydrogen‑electric tug supports Qingdao Port’s vision as a “hydrogen + intelligent” facility, advancing China’s broader initiative to decarbonize its maritime infrastructure. Importantly, this breakthrough fills critical domestic gaps in hydrogen energy application within China’s shipping sector.
Wis Matters
This landmark marks a significant shift in maritime operations:
-
Environmental Impact – By eliminating local emissions and reducing greenhouse gases, the tug contributes substantially to port-level sustainability efforts.
-
Technological Advancement – The hybrid powertrain and autonomous charging systems position Tug No. 1 at the cutting edge of maritime innovation.
-
Global Implications – Qingdao’s success may serve as a model for other major ports seeking low- or zero-emission tug solutions, accelerating green shipping worldwide.
China has recently accelerated development in maritime hydrogen applications, including hydrogen-powered port cranes, refueling infrastructure, and green logistics integration. Tug No. 1 represents a culmination of these efforts and positions Qingdao as a leader in clean energy ports.
The commissioning of Tug No. 1 is more than a technological achievement—it is a strategic move toward sustainable maritime operations. By pioneering hydrogen-electric propulsion in tugboats, Qingdao Port sets a high standard in the global quest for decarbonized shipping.
