Corvus Orca Energy

The Orca Energy ESS represented a shift in the maritime industry when launched in 2016. No other Energy Storage System can compete with the installation count of the Orca Energy system. Outstanding results and the highest level of safety has set the new industry-standard for maritime batteries.


When launched, Corvus Energy combined its industry-leading research and development capabilities with several years of experience from having the largest global installed base of ESS solutions to build the industry’s safest, most reliable, high performing and cost-effective maritime ESS.

Applications

Orca Energy is ideal for applications that are in need of both energy and a high amount of power, moving large amounts of energy at an inexpensive lifetime cost per kWh. Typical vessel-types are:

  • Ferries
  • Cruise ships
  • Ro/Ro – Ro/Pax
  • Yachts
  • Offshore vessels
  • Rigs
  • Tugs
  • Fishing vessels
  • Merchant vessels
  • Port cranes
  • Shore charging
  • Fish farms

Features

Corvus Energy safety innovations

Passive single-cell Thermal Runaway (TR) Isolation

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

 

Exceeds Class and Flag requirements for TR gas venting

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