Corvus launches battery with unlimited capacity for cruise ships, ro-pax, ro-ros

(BERGEN, Norway and RICHMOND, British Columbia) — Corvus Energy, a leading supplier of batteries for hybrid and zero-emission vessels, has introduced its next-generation energy storage system (ESS): Corvus Blue Whale for cruise ships, ro-pax and ro-ro vessels.

“When we launched the Corvus Orca Energy in 2016, we set a new standard for performance, safety and economics in a maritime ESS," said Geir Bjorkeli, CEO of Corvus Energy. " The Corvus Orca Energy became an enormous success when launched and is now on more than 140 vessels worldwide. 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 decarbonization,” he said.

“One battery cannot fit all applications,” said Halvard Hauso, EVP sales and marketing, explaining Corvus’ decision to expand its product range. “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. Corvus Orca Energy is ideal for applications that require high charge/discharge rate combined with high energy demand such as ferries and offshore vessels.

“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.”

The cruise and ferry industry are facing stricter rules and regulations, along with an increasing demand from passengers for green transportation solutions. By using energy-dense battery cells and a space-saving design, Corvus Blue Whale's volume per kWh is reduced by 50 percent and the weight per kWh is reduced by 30 percent. Its modular design uses quick connectors for easy commissioning and reduced installation costs.

Like the Corvus Orca Energy, the new Corvus Blue Whale design uses passive air-cooling and incorporates Corvus’ patented single-cell thermal isolation to achieve the highest safety standard in the industry.

“Moreover, Corvus Blue Whale has no limitations with regards to size,” said Bjorkeli. “We expect to see multi-megawatt hour ESSs deployed before long as cruise and passenger transportation operators grapple with zero-emissions regulations. We may look back on the launch of Corvus Blue Whale as another inflection point in the greening of the maritime industry.”

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