Corvus ESS powers cruise ships and ferries

Corvus Blue Whale is said by chief executive, Geir Bjørkeli, to ‘reinvent energy storage for ships’.

“The Corvus Orca Energy became an enormous success when launched [in 2016] and is now on more than 140 vessels worldwide,” he said.

“Looking back, we can see the significant role Corvus Orca Energy played in driving development towards a greener maritime industry. Our goal is for Corvus Blue Whale to have a similar impact on maritime decarbonisation.”

Halvard Hauso, executive vice president of sales and marketing, said that one battery can not fit all applications. “To keep the emissions and costs as low as possible and allow for enough operational freedom, we need to adapt the batteries to the different vessel types,” he explained.

“Corvus Blue Whale is ideal for applications that require low charge/discharge rate combined with very high energy demand such as cruise, ro-pax and ro-ro vessels.”

By using energy-dense battery cells and a space-saving design, volume per kWh is reduced by 50% and the weight per kWh is reduced by 30%. Using passive air-cooling and single-cell thermal isolation, the modular design enables easy commissioning and reduced installation.

The Corvus Blue Whale is being unveiled publicly for the first time at Nor-Shipping in Oslo on 4 – 7 June.
