Key Features
Key Features
The Corvus Blue Whale NxtGen ESS is designed for use in medium to large vessels, including retrofits, with system sizes from 1MWh to 200+MWh.
It is particularly well suited for operational profiles which call for slow charge and discharge rates; however, it can provide high charge and discharge for short durations when needed. It is ideal for applications which require the ability to sail emission-free over longer periods of time, including during emission-free port stays, at a cost-effective kWh price.

Functions
Functions
Extending the range of zero-emission operations for Cruise, Ro-Pax, and other large maritime vessels
Blue Whale was developed with large marine energy storage installations in mind, specifically battery systems that require more than 10MWh total system energy. Optimization for energy density enables Blue Whale to deliver more power. This in turn extends the vessel’s ability to maintain zero-emission operations, including during transit through emissions-restricted zones and zero-emission port stays.
Industry leading volumetric and gravimetric room energy density
Designed for voltages up to 1232 VDC
Very cost-efficient for large installations
Weight and volume reduced ~30% and ~50 % compared to Corvus Orca ESS
Flexible and modularized design
Simplified installation and servicing
Passive single-cell Thermal Runaway protection
Scalable capacity and voltage according to vessel requirements
Multiple cell options available for performance/lifetime optimization
Industry-proven Battery Management System (BMS)
Remote monitoring capabilities
Corvus NxtGen architecture supports service parts availability
Architecture adaptable for next-generation products
Cobalt-free and rare-earth-free, designed for recyclability and ESG compliance
Enhanced EMI immunity design for maritime environments
Advancing marine energy storage technology with the Corvus Blue Whale
The Corvus Orca ESS, the most installed marine energy storage system worldwide, set the industry standard for maritime energy storage reliability and safety. The Blue Whale design incorporates the unsurpassed safety features of the Orca, and additionally provides key advances required to meet the energy demands of large vessels. This includes improved energy density, with weight and volume reduced by ~30% and ~50 % compared to Orca.
