Australian shipbuilder Incat Tasmania has powered up the world’s largest battery-electric ship, a monumental ferry known as Hull 096, marking a historic leap for zero-emission maritime transport. The 130-meter vessel, under construction for South American ferry operator Buquebus, was energized during its first e-motor trial, showcasing a propulsion system with over 40 megawatt-hours (MWh) of battery capacity—four times larger than any previous maritime installation.
The milestone event, held on Sunday at Incat’s shipyards north of Hobart, was witnessed by dignitaries including Australia’s Trade Minister Don Farrell and Tasmanian Premier Jeremy Rockliff. Robert Clifford, Incat Chairman, described the trial as a “remarkable achievement” and a “turning point for shipbuilding.” He emphasized the global significance, stating, “This is the first time a ship of this size, anywhere in the world, has been trialled under 100 per cent battery-electric propulsion.”
The scale of the project is staggering. Hull 096 is designed to carry 2,100 passengers and more than 220 vehicles across its massive deck. Its heart is a 250-tonne battery system that will enable high-speed, silent, and emissions-free operation.

Originally conceived as an LNG-powered ferry named China Zorrilla, the design was revised during the pandemic to embrace full electrification, a decision that has now positioned it as the vanguard of a new shipping era.
For Incat Tasmania, a leader in aluminium shipbuilding, this success is both a culmination and a launchpad. The company has recently secured a series of follow-on contracts that cement its role as an industry pioneer. In July, it announced a deal with Danish ferry operator Molslinjen to build two 129-meter, 100 per cent battery electric ferries, each featuring a 45 MWh battery system.
Earlier this month, Molslinjen exercised an option for a third identical vessel. These ferries will carry 1,483 passengers and 500 cars at speeds over 40 knots, proving that electric propulsion can meet the demands of some of the world’s busiest ferry routes.

The activation of Hull 096 is more than a technical test; it’s a powerful signal to the global shipping industry. Maritime transport is a significant contributor to global carbon emissions, and the sector has been searching for scalable, clean alternatives to heavy fuel oil.
This vessel demonstrates that large, high-capacity, high-speed electric ships are not just a concept but a commercial reality. The technology leap is immense—the 40 MWh battery pack is equivalent to the capacity of roughly 500 average electric car batteries, all integrated into a single marine drivetrain.
As Hull 096 undergoes final outfitting and sea trials before its journey to South America, its implications ripple far beyond the River Derwent. It proves that electric ferries can be built at scale, offering a viable blueprint for decarbonizing coastal and short-sea shipping routes worldwide. For Tasmania, it reinforces the island state’s reputation as a hub of maritime innovation. For the planet, it represents a tangible, floating step toward a cleaner future, one where crossing the water doesn’t come with a cloud of smoke.
