Corvus Blue Whale

Corvus Energy has combined its industry leading research & development capabilities and knowledge gained from having the largest global installed base of ESS solutions to develop a new groundbreaking energy storage system. The new ESS meets the energy needs required to operate emissions-free for longer periods of time.

The Corvus Blue Whale ESS is different than the ESS technology already in use. It is designed for vessels that are in need of slow charge and discharge rate, such as Cruise, Ro-Pax, Ro-Ro, and Mega Yachts. It allows these ships to sail emissions-free for longer periods of time or to stay emissions-free in port. Size is typically from 20 -50 MWh, which means that low weight and volume is essential.

Corvus Energy safety innovations

Passive-Single-Cell-level Thermal Runaway (TR) Isolation

  • True cell-level thermal runaway isolation
  • TR does not propagate to neighbouring cells
  • Isolation NOT dependent on active cooling

 

Exceeds Class and Flag standards TR Gas venting

  • Integrated thermal runaway gas exhaust system
  • Easily vented to external atmosphere rather than the battery room

 

Additional fire suppression system not required.
