Corvus Energy to supply 40 MWh battery systems for fully-electric ferry

Energy storage systems (ESS) firm Corvus Energy has been selected by technology group Wärtsilä to supply the battery systems for what is claimed as the world's largest fully-electric lightweight Ro-Pax ferry. The battery systems are scheduled to be delivered by the end of 2024, with the vessel entering operation in 2025.

The Norway-based company claims that with more than 40 MWh of energy storage capacity, this will be the largest battery system ever installed onboard a ship - about four times as big as the current largest installation. The ship will also have the longest zero-emission range at the highest speed, and will be charged with the world's highest capacity chargers, Corvus adds. 

The 130 metre long ferry, which can house 2100 passengers and crew, 225 cars, and a 2000-square meter duty-free shop, will be built by Incat shipyard in Tasmania for its South American client Buquebus for plying between Argentina and Uruguay.

"This groundbreaking project marks a turning point in the maritime industry's effort to transition towards greener means of transportation", said Halvard Hauso Commercial Director Europe, Corvus Energy. "Combining cutting-edge technology, environmental consciousness, and innovative design, it redefines the future of ferry operations worldwide and paves the way for other large, zero-emission vessels". 

He further added, "We are very grateful that Wärtsilä once again chose Corvus Energy as their partner for such an important and advanced project." 

Corvus Energy claims that its lightweight battery 'Dolphin NextGen' is based on the architecture designed for 'Blue Whale ESS'. The Blue Whale development included a ground-up redesign that reevaluated and improved every aspect of battery design, including battery chemistry, mechanical and electrical design, and software building blocks. 

Further, the Dolphin NextGen ESS is a game changer for marine battery projects due to its low weight and volumetric density, robustness, and unsurpassed flexibility, the battery developer claims.
