Maritime energy storage system (ESS) provider Corvus Energy has been granted type approval (TA) by DNV for its Blue Whale NxtGen Energy battery system, in both air-cooled and liquid-cooled configurations.
The TA confirms that Blue Whale NxtGen Energy meets DNV’s requirements for safety, quality and performance. It gives shipowners, shipyards and system integrators independent verification that the system is ready for a range of maritime applications.
Blue Whale NxtGen Energy is targeted at vessel owners seeking maximum energy capacity, operational flexibility, and proven safety in large-scale battery installations. Built on Corvus Energy’s next-generation rack-free and modular architecture, it is considered suitable for large electric and hybrid ferries, ro-pax vessels, cruise ships, offshore vessels, and other applications that require substantial energy storage and extended zero-emission operation.
The system combines LFP (lithium iron phosphate) chemistry with advanced battery management, cybersecurity, and lifecycle support to deliver reliability and long service life. Its modular design is intended to simplify installation, improve space utilisation, and to allow systems to scale from smaller hybrid applications to some of the world’s largest battery-powered vessels. With independent DNV TA and a growing track record in high-capacity projects, Blue Whale NxtGen Energy can provide shipowners, shipyards, and designers with a safe, cost-effective, and future-ready energy storage solution that supports the maritime industry’s transition to low- and zero-emission operations
Thor Humerfelt, Corvus Energy Head of Product Innovation, said: “Type approval for Blue Whale NxtGen Energy is an important milestone for Corvus Energy and for the maritime industry’s transition to low- and zero-emission operations. We see a clear trend towards larger battery installations, as the economics of electrification improve and vessels need longer electric range and more operational flexibility. With Blue Whale NxtGen Energy, we combine proven LFP technology, high safety and a competitive cost profile with significantly more energy capacity, so customers can deploy larger and more cost-effective battery systems with confidence. Having secured more than 100 MWh in confirmed orders already proves the trust in the design and quality of our products.”
Vessel battery systems are believed to be growing quickly in size, with rising fuel costs and stricter emissions regulations strengthening the business case for electrification, so owners are specifying longer electric range and more fully electric operation. The NxtGen platform is designed for this development. Its rack-free, modular architecture allows flexible integration and makes efficient use of the space on board. The scalable design simplifies installation and supports multi-MWh energy storage systems, reducing system complexity and making better use of the available battery room.
