Mega batteries can cut cruise ferries’ emissions to zero during port stays

Corvus Energy has installed mega batteries on two Ro-Pax cruise ferries which will allow the crew to cut diesel power to the boat for four hours during a port stay

A Norway-based company says it has completed the installation of mega batteries on two Ro-Pax cruise ferries which operate in the Mediterranean.

The new 5.5 MWh battery energy storage system, or ESS, will allow the crew to shut off the diesel engines and operate the ship solely on battery power and with zero emissions for up to four hours during a port stay.

Corvus Energy retrofitted the Cruise Barcelona and Cruise Roma, which are both owned and operated by the Grimaldi Group of Italy.  The ships have passenger capacity of 3,500 and can accommodate 1,000 vehicles.

“The Corvus energy storage system is an important component in our vision for sustainable shipping,” said Andrea D’Ambra, Energy Saving Technical Department at Grimaldi Euromed, a Grimaldi Group company which operates Pure Car & Trucks Carriers, ro/ro and passenger ferries in the Mediterranean Sea and Northern Europe.

Roger Rosvold, Senior Vice President of Sales at Corvus Energy said an “ESS this massive had never been retrofitted onboard a cruise ferry vessel.”

“Its clear now that if shipowners are willing to go green, the technology exists,” said Rosvold, adding “At Corvus, we will continue to drive technology further by pushing boundaries for the use of batteries.”

According to a press release from Corvus Energy, the projects began with technical teams from Grimaldi and Corvus Energy sailing aboard the Cruise Barcelona to evaluate the optimal electrical and mechanical integration of an energy storage system.

“Good collaboration and close partnership are key in developing new and innovative solutions to accelerate the adoption of green technology,” said Rosvold.

Corvus Energy says it provides battery power to more hybrid or all-electric ferries and all other providers of energy storage systems combined.  The company has experience in over 200 projects, totalling over 200 MWh and more than two million operating hours.
