A significant milestone in sustainable maritime transport has just been reached, with the launch of the world’s largest fully electric ship in Tasmania.

Named China Zorrilla, the cutting-edge vessel was developed by Australian shipbuilder Incat and will operate under South American ferry company Buquebus.
At over 130 metres (426 feet) long, the China Zorrilla sets a new standard in electric-powered marine travel, boasting a battery system four times larger than any previously installed on a ship.
The new vessel will ferry passengers between Buenos Aires, Argentina, and Uruguay.
It has capacity for 2,100 passengers and 225 vehicles, making it not only the largest electric ship by battery size but also one of the most capacious ferries in its class.
A Technological Feat in Maritime Engineering
Incat Chairman Robert Clifford hailed the launch as “a giant leap forward in sustainable shipping,” praising the development as crucial not only for the company but for the global shipping industry.
The China Zorrilla is fitted with over 250 tonnes of batteries, giving it more than 40 megawatt-hours (MWh) of storage capacity. This powers eight advanced electric waterjets built by marine propulsion manufacturer Wärtsilä.
“This isn’t just a ship – it’s the future… The China Zorrilla proves that large-scale, low-emission transport solutions are not only possible, but they are ready now.”
Incat CEO Stephen Casey
Although the vessel has officially been launched, some work remains before it begins active service.
Final outfitting of the ship’s interior is still underway, including installation of its vast 2,300-square-metre duty-free shopping space, which will be the largest retail area aboard any ferry worldwide.
Final battery installation and the integration of the energy storage system are also in progress, with sea trials expected later in 2025.
The ship has been named in honour of China Zorrilla, the renowned Uruguayan actress and cultural icon who passed away in 2014.
With its impressive size and zero-emission propulsion system, China Zorrilla is expected to become a global model for sustainable shipping.
Experts in green transportation have pointed out that the ship’s massive flat deck provides significant opportunity for solar panel integration, which could further enhance its renewable capabilities.
While it’s a huge achievement for ferry travel, it doesn’t mean that the technology is ready for cruise ships.
Even small luxury cruise ships are much bigger than China Zorrilla, and would require a lot more power to tackle the various onboard facilities that you’d find on cruise ships.
Still, it’s potentially a very exciting development and who knows – maybe we aren’t too far away from the first electric-powered cruise ship, even if it would end up being a smaller one for now!
