Corvus Energy and BYD Energy Storage have signed a strategic cooperation agreement aimed at accelerating the development of next-generation battery systems for the maritime sector.
The agreement marks the next stage of cooperation between the two companies, following a memorandum of understanding signed in December 2025. It focuses on the co-development of lithium iron phosphate, or LFP, battery systems designed specifically for marine applications.
The partnership will support joint work in technology development, resource sharing, market expansion, research and development, certification, and large-scale deployment of high-rate LFP battery systems for ships and offshore maritime operations.
Fredrik Witte, CEO of Corvus Energy, said the agreement would strengthen the company’s ability to deliver competitive battery solutions at scale. He noted that the collaboration is expected to reduce system costs significantly while maintaining the safety and performance standards required by the maritime industry.
LFP battery technology is increasingly attracting attention in shipping because of its safety characteristics, long cycle life, and potential cost advantages compared with some other lithium-ion battery chemistries. For maritime operators, these features are important as the sector continues to adopt hybrid and fully electric propulsion systems to reduce emissions, improve energy efficiency, and comply with tightening environmental regulations.
The cooperation between Corvus Energy, a major supplier of marine battery systems, and BYD Energy Storage, part of one of the world’s largest battery technology groups, could help scale up the availability of marine-grade LFP battery solutions. This is particularly relevant for ferries, offshore vessels, workboats, harbour craft, short-sea shipping, and other vessel segments where battery-electric or hybrid-electric systems are becoming more commercially attractive.
The agreement was signed during a ceremony at the China International Battery Fair, CIBF, in Shenzhen, with representatives from both companies in attendance.
As shipping moves toward decarbonization, strategic partnerships between maritime technology providers and global battery manufacturers are expected to play an increasingly important role. Battery systems are now central to many vessel electrification projects, especially where operators are seeking lower fuel consumption, reduced emissions, improved redundancy, and quieter operations.
While the agreement does not remove the technical challenges associated with marine battery deployment, including safety certification, thermal management, integration with vessel power systems, and lifecycle cost management, it signals growing momentum behind LFP technology as a practical option for the maritime energy transition.
The collaboration between Corvus Energy and BYD Energy Storage therefore represents another step in the wider shift toward cleaner, more efficient, and more scalable energy-storage solutions for the maritime industry.
