Corvus Orca Energy

Designed and purpose built for the maritime industry, the Corvus Orca Energy storage system (ESS) created a shift in the maritime energy storage segment. No other ESS matches the installation count of Orca Energy. Continuous focus on development and high safety levels have set the industry standard for all maritime ESSs.

Applications

Orca Energy is ideal for applications where you need to move large amounts of energy multiple times per day, efficiently and at low cost. Orca Energy is suitable for both all-electric and hybrid installations.

Corvus Energy safety innovations

Passive single-cell Thermal Runaway (TR) Isolation

  • True cell-level thermal runaway isolation – TR does not propagate to neighbouring 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

 

Additional fire suppression system not required.
