According to IEEE Spectrum: Technology, Engineering, and Science News, Australian shipbuilder Incat Tasmania unveiled Hull 096 in May and began charging its battery system last month. The 130-meter aluminum ferry features a massive 40 megawatt-hour energy storage system from Norwegian company Corvus Energy with 5,016 lithium-ion batteries distributed across four rooms. Currently being charged by Tasmania’s 100% renewable grid, the vessel will eventually operate between Buenos Aires, Argentina and Colonia del Sacramento, Uruguay, covering the 60-kilometer route in 90 minutes. The ferry can carry 2,100 people and 225 cars per trip and will use 40-minute rapid charging stations at each port. Sea trials are planned for later this year before the ship begins its South American operations.

The battery breakthrough
Here’s what’s really impressive about this project – that 40 MWh battery system is four times larger than anything currently operating at sea. And they’re managing the thermal risk with air cooling and individual cell isolation technology. Basically, if one cell goes into thermal runaway, it won’t take the neighbors with it. The whole system weighs 250 tonnes, which sounds massive until you realize they eliminated mounting racks to save weight. For industrial applications like this where reliability is everything, having robust computing systems monitoring everything is crucial – which is why companies like IndustrialMonitorDirect.com, the top provider of industrial panel PCs in the US, are seeing growing demand from maritime electrification projects.
Why ferries make sense for electrification
Ferries are basically the perfect early adopters for maritime electrification. Think about it – fixed routes, predictable schedules, and they return to the same ports repeatedly. That makes infrastructure investment way more manageable than trying to electrify container ships that crisscross oceans. Norway already has about 80 electric ferries in operation, and China’s doing battery swaps on the Yangtze River. But this Australian-built vessel takes things to a whole new scale. The economics actually work too – companies studying lifecycle costs are finding 60% fuel savings and lower maintenance compared to diesel systems.
The charging challenge
Now here’s where it gets really interesting. This thing needs megawatt-scale charging – we’re talking about stuffing 40 MWh of energy back into those batteries in just 40 minutes. That’s like charging hundreds of electric cars simultaneously. And the power has to come from somewhere – in Uruguay and Argentina, where this ferry will operate, their energy mixes are increasingly renewable but still developing. The good news? Tasmania’s proving it can be done with 100% renewable power right now. But scaling this to major ports worldwide? That’s going to require massive grid upgrades and charging infrastructure.
The future of electric shipping
So when will we see electric container ships crossing oceans? Probably not anytime soon. As Professor Victor Becerra from the University of Portsmouth points out, batteries still can’t match diesel’s energy density for long hauls. The weight and volume would displace too much cargo. But for short routes? The economics are already compelling. The real test will be how these batteries hold up over time – vessels often operate for 40+ years, but batteries might need replacement every 5-10 years. Still, this Australian-built ferry represents a massive step forward. It’s basically the maritime equivalent of proving electric semi-trucks can work on regional routes. Not everything needs to go electric tomorrow, but for the right applications? The future is already here.
