Finnish technology group Wärtsilä has revealed it will provide its battery electric propulsion system and waterjets for the world’s largest battery-electric ferry.

The vessel is a new Ro-Pax ferry being built by Incat Tasmania and has been ordered by South American shipowner Buquebús. The Finnish firm has contracted Corvus Energy to provide the battery systems for the vessel. The company’s lightweight battery, Dolphin NextGen, is based on the architecture of the 4-year, multi-million development program for the Corvus Blue Whale ESS.
