A 130-metre battery ferry starts carrying passengers across the River Plate

Incat's China Zorrilla, billed as the largest battery-electric ship, has made its first commercial crossing between Buenos Aires and Colonia.

The China Zorrilla, a 130-metre ferry built by Incat Tasmania for its long-time customer Buquebus, has completed its first commercial voyage. It sailed between Buenos Aires, Argentina, and Colonia, Uruguay, across the River Plate. The announcement came on October 29, 2026, and the ship is now in passenger service.

Incat describes it as the world's largest battery-electric ship. It runs entirely on batteries and can carry up to 2,100 passengers and 225 vehicles. The builder calls it one of the most ambitious and technically complex projects it has undertaken, after years of design, engineering and construction.

Why it matters: a short, busy crossing like this one is a good fit for electric power. Ferries run fixed routes and repeat them often, so charging can be planned around the timetable. A ship carrying thousands of people and hundreds of vehicles that burns no fuel on the way is a real test of whether electric propulsion can handle heavy passenger work. If it holds up in daily service, it points to cheaper operation and cleaner transport on similar routes, and to more demand for grid power and storage at ports.

What to watch: the source gives no figures for battery capacity, range, fuel savings or emissions cuts, and the size and status claims come from Incat, the builder. The idea that this proves commercial viability is the story's framing, not something the company statement says. Reliability, running costs and charging arrangements over the coming months will show whether it does.
