Corvus Energy has introduced the Blue Whale NxtGen, a high-energy marine battery system the company says is built for an era of tougher environmental rules and increasingly power-hungry vessels

The Blue Whale NxtGen uses cobalt-free LFP cells and is designed for a lifespan of up to 15 years.

Corvus argues this longer service window translates directly into lower ownership costs for shipowners who are already wrestling with ESG requirements and tightening emissions standards.
