• Corvus Energy launches Blue Whale NxtGen Power, an LFP system using BYD cells
• First commercial product from the partnership announced in December 2025
• Aimed at vessels where power demand, not energy capacity, drives system design
• To be presented at SMM in Hamburg on September 2

Norway's Corvus Energy has launched a high-power lithium iron phosphate battery system developed with China's BYD Energy Storage, the first commercial product from the partnership between the two companies.

The Blue Whale NxtGen Power system is aimed at vessels where power demand rather than energy capacity defines performance, Corvus said in an emailed press release on Wednesday, naming tugs, workboats, offshore vessels using batteries for power optimisation, and large ferries needing rapid charging between crossings.

Under the arrangement, BYD supplies the battery cell technology and cell stack manufacturing, while Corvus delivers the system design and architecture, including marine safety features, battery management, cybersecurity, class approval, final assembly, and lifetime service support.

Corvus says the combination lets it bring products to market more quickly while keeping control of the elements that define safety and compliance.

"LFP technology has advanced significantly in recent years and now offers a highly cost-effective solution for a wide range of maritime applications," said Thor Humerfelt, head of product innovation at Corvus Energy.

"By combining BYD Energy Storage's technology leadership, manufacturing expertise and global scale with Corvus Energy's maritime experience, we can accelerate innovation, reduce system costs and deliver even greater value to our customers."

The system is built on Corvus's existing NxtGen platform, sharing its stack interface, module design, and battery management system, which the company says keeps installation and service procedures largely unchanged for existing customers.

The two companies signed a memorandum of understanding in December 2025 and a strategic cooperation agreement in May 2026, covering co-development of marine battery systems based on high-rate LFP technology.

Corvus says more than 50% of the world's vessels fitted with zero-emission technology are powered by its systems, with over 1,400 projects delivered.

The system will be presented alongside Corvus's full LFP portfolio at SMM in Hamburg on September 2.
