Summary:

Hull 096 [the ferry] is equipped with more than 250 tonnes of batteries and an energy storage system (ESS) with more than 40 megawatt-hours of installed capacity.

The ESS [Battery] is four times larger than any previous maritime installation in the world and is connected to eight electric-powered water jets.

"It's the future of short, sea shipping," Incat founder and chairman Bob Clifford said. "Today, the technology is good for 80 to 160 kilometres. It won't be long until it's good for 320km, and maybe in 10 years' time it's good for 640km. So the advancement of electrical ships is going to continue. [...] From the ship's berths in Argentina and Uruguay, a full charge was expected to take 40 minutes"

I posted this article as it really highlights the scale of electric ships. Its battery is the size of 500-1000 electric cars, yet it can only drive for 90 minutes.

The math on the charging is also interesting, it only takes 40 minutes to charge the 40 MWh battery. Thats an average charging speed of 60 MW. Impressive!
