Corvus Energy has received DNV Type Approval for its Blue Whale NxtGen Energy battery system, covering both air-cooled and liquid-cooled configurations.
Announced on 5 October, the approval confirms that the lithium iron phosphate (LFP) battery system meets DNV requirements for safety, quality and performance.
Battery system targets larger marine applications
The Blue Whale NxtGen platform has been developed for vessels requiring high-capacity energy storage. Potential applications include fully electric and hybrid ferries, RoPax vessels, cruise ships and offshore vessels.
The system uses a modular architecture that removes the need for conventional battery racks. According to Corvus Energy, this approach is intended to simplify installation while improving the utilisation of available battery-room space.
The platform supports multi-megawatt-hour installations and integrates battery management, cybersecurity features and lifecycle support.
Corvus reports more than 100 MWh in confirmed orders
Corvus Energy said confirmed orders for the Blue Whale NxtGen system have surpassed 100 MWh.
Thor Humerfelt, Head of Product Innovation at Corvus Energy, said demand for larger marine battery installations is being driven by improving economics for electrification, alongside vessel operators’ requirements for longer electric range and greater operational flexibility.
The DNV Type Approval provides shipowners, shipyards and system integrators with independent verification of the battery system as they evaluate energy-storage technologies for marine electrification projects.
