The electric ship China Zorilla, the largest electric ship in the world, has officially entered commercial service, marking a significant achievement for the maritime industry and the growing use of electric propulsion in large passenger vessels.
First Commercial Voyage
The 130-meter China Zorilla, built by Australian shipbuilder Incat Tasmania for ferry operator Buquebus, made its first commercial voyage between Buenos Aires, Argentina, and Colonia, Uruguay, on October 22.
Technical Features and Ship Capacity
This high-speed catamaran can carry up to 2,100 passengers and 225 vehicles and operates entirely on battery power, eliminating the need for conventional marine engines. At the heart of this ship is an energy storage system with a capacity of over 40 megawatt-hours, consisting of more than 250 tons of batteries. This system powers eight electric water jets, making China Zorilla the largest electric ship ever built.
The ship is supported by high-power charging infrastructure at both river terminals, allowing it to recharge its batteries between trips.
The launch of commercial services was marked by an official ceremony in Buenos Aires on October 21, attended by the CEO of Incat Tasmania, Craig Clifford, representatives from Buquebus, and maritime and government officials from Argentina and Uruguay.
Clifford described this achievement as one of the great honors in the company's history and credited the hundreds of workers at the Incat facility in Hobart who overcame engineering challenges to bring this ship into operation.
The China Zorilla also offers a different experience for passengers. Without conventional diesel engines, this ship operates with less noise and vibration and produces no direct exhaust gases during the journey. These changes were significant for passengers, especially on such a large vessel.
The project to build this ship is particularly important given its developments during construction. It was initially designed to use dual-fuel engines capable of burning diesel and liquefied natural gas, but was ultimately redesigned for full electric propulsion, which required significant engineering changes.
The entry of China Zorilla into service demonstrates the growing potential of battery-electric technology in high-capacity ferry operations, especially on fixed routes where shore-side charging infrastructure can support regular trips.
