Corvus Energy, the world’s leading supplier of marine energy storage solutions,  announced the launch of Blue Whale NxtGen, the latest addition to its NxtGen family of batteries. Designed for vessel applications where high energy content and density are critical, Blue Whale NxtGen delivers unmatched lifecycle cost, safety, and performance while maintaining modularity, scalability and unique level of digital services.

NxtGen Architecture and prolonged lifetime

Blue Whale NxtGen empowers the industry to reduce emissions, optimize operations, and prepare for the regulatory and environmental demands of tomorrow. At the core is the full integration of Corvus’ NxtGen architecture, which combines modularized design, cost efficiency and advanced BMS and analytics. In addition, cobalt free LFP cells with market leading performance and prolonged lifetime up to 15 years enable shipowners to lower capital expenditures and meet ESG targets. The BW NxtGen ESS will have a 1C charge / discharge rate which makes the product suitable for both energy and more power demanding operational modes.

Significant leap forward in marine energy storage

“Blue Whale NxtGen is more than a new product launch — it represents a strategic step forward for Corvus Energy and the maritime industry. Without compromising on Corvus´ strong focus on quality, safety, security and sustainability, we are introducing contract manufacturing to optimize cost, stronger focus in China, more robust diversified global sourcing and the ability to swap battery cells without changing the product design” says Fredrik Witte, CEO of Corvus Energy

“This platform strengthens our position as the trusted partner for green maritime solutions and ensures our customers’ investments remain relevant as the industry continues to evolve.”

Balancing sustainability with strong business value
“Our customers are asking for solutions that balance sustainability with strong business value. Blue Whale NxtGen delivers exactly that — higher energy density, longer lifecycle, and simplified installation, all backed by stronger global presence with expertise closer to our customers.  For shipyards this means more cost optimized supply chain, installation and technical support. For shipowners this helps us reduce life cycle costs, meet ESG commitments, and stay ahead of regulatory changes without compromising performance,” says Ole Jacob Irgens Head of Sales EMEA and Asia at Corvus Energy. “It’s a platform designed not only for today’s challenges but for the opportunities of tomorrow.”

Blue Whale NxtGen will have Corvus’ in-house designed 4th-generation Battery Management System (BMS), data ownership, and industry-leading cybersecurity standards that further strengthen operational trust.

The first projects will be delivered in Q4 2026.
