As rules and regulations for emissions-free sailing get stricter, an increase in Ro-Pax shipowners consider how they may implement an Energy Storage Systems (ESSs) to comply with the regulations and, at the same time, be more energy efficient in their operations.

A Ro-Pax typically use ESS for:

  • Optimized energy consumption by load levelling
  • Maneuvering into port and in shallow waters
  • Zero emission in port
  • Increased safety and reliability – including black-out prevention
  • Black start capability
  • Reduced scrubber system size for ECA compliance


  • Reduced fuel consumption
  • Reduced emissions
  • Safer operations
  • More silent operations when in zero-emission mode

Corvus Energy ESS is suitable for both newbuilds and retrofit projects. To learn more about our products, please visit our product pages.
