A ferry the length of a football pitch just crossed open ocean water on nothing but batteries, carrying more than two thousand passengers in the process. The China Zorrilla, the largest battery-electric vessel ever built, completed its first commercial voyage between Buenos Aires, Argentina, and Colonia del Sacramento, Uruguay, on October 21, 2026.

  • 130m long, 32m wide — three decks plus a 2,300 m² duty-free retail complex
  • 2,100 passengers and 225 vehicles per crossing
  • 40+ MWh of battery energy from over 250 metric tons of Corvus Energy batteries
  • 55-60km route completed in roughly 90 minutes at 25 knots

An engineering bet that paid off

The ship was built by Incat Tasmania, an Australian shipbuilder, for ferry operator Buquebus, and was previously known internally as Incat Hull 096 before being named after the late Uruguayan actress and cultural icon Concepción "China" Zorrilla. It was launched in Buenos Aires on October 21, with officials from Incat, Buquebus, and maritime authorities from both Argentina and Uruguay in attendance.

Battery-electric propulsion has powered small ferries and short-hop vessels for years, but scaling it up to a high-capacity, open-water vessel carrying thousands of people was an unproven bet. Eight electric motors driving waterjets push the China Zorrilla to 25 knots, fast enough to cover the roughly 55-to-60-kilometer Río de la Plata crossing in about 90 minutes — comparable to a conventional diesel ferry on the same route.

"China Zorrilla is proof that high-capacity vessels can sail using battery-electric propulsion," said Robert Clifford, chairman of Incat.

Where the electricity actually comes from

A battery-electric ship is only as clean as the grid charging it. In this case, the China Zorrilla draws power from the Uruguayan electricity grid, which Incat says is supplied in part by wind farms and hydropower, before that electricity is stored in the ship's batteries between crossings.

That combination lets the vessel eliminate the vibrations, diesel exhaust, and carbon emissions of a conventional ferry engine on every crossing. Passengers travel across one of South America's busiest ferry routes without the diesel fumes typically associated with large passenger vessels, detailed by Marine Insight.

What comes next for electric shipbuilding

Incat Tasmania isn't treating the China Zorrilla as a one-off showpiece. The company is already building three more 129-meter battery-electric catamarans, plus two hybrid vessels, for European and international ferry operators, signaling it sees this as a repeatable, scalable design rather than a novelty project limited to one South American route.

Incat says it is positioning itself as a leader in electric aluminium shipbuilding, framing the China Zorrilla as proof that the barrier to large-scale electric shipping was engineering and battery density, not fundamental physics.

For the roughly 2,100 passengers riding across the Río de la Plata on any given crossing, the experience is likely to be fairly mundane: a smooth, quiet ferry ride between two countries. That ordinariness is the point. The China Zorrilla's real achievement isn't novelty, it's normalcy — making a zero-emission crossing feel exactly like any other ferry trip, just without the diesel engine underneath.
