Chinese battery supplier EVE Energy and Green Whale Technology (GWT) have signed a strategic partnership agreement to provide marine battery energy storage systems (BESS) and service to customers worldwide.
The collaboration combines EVE Energy’s lithium marine battery system technology and GWT’s marine engineering, lifecycle service and commissioning expertise. The strategic agreement is structured as a back-to-back partnership to ensure EVE Energy provides comprehensive support, the companies said.
EVE Energy and GWT are actively expanding their presence in the tanker, container, public transport, heavy lift, port, offshore, aquaculture, short sea shipping and yachting markets. They are currently developing a new battery product based on two new types of battery cells, which is expected to come into the market in 2026.
The companies have already delivered a BV-class marine battery container in Asia.
While the high C-rate maritime battery market has been dominated by nickel manganese cobalt (NMC) cell-based systems, EVE supplies LFP marine batteries, which can offer a longer lifetime than NMC-based systems in many application scenarios. EVE’s active balancing technology enables the systems to deliver a lifetime of up to 15 years, reducing total cost of ownership.
To support customers globally, Green Whale Technology is establishing a Netherlands-based cloud service platform for local data compliance, digital security and mitigating geopolitical risks. Spare parts storage in Norway and the Netherlands will allow it to provide timely after-sales support in Europe.
EVE Energy’s BESS factory has the capacity to produce over 10 MWh per day to ensure scalability and timely delivery. The marine battery system is priced below $300 per kWh.
“By collaborating on all the key elements in BESS development, manufacturing, delivery and service, we aim to ensure that customers receive the best available battery technology, backed by global support throughout the product lifecycle of our systems. We are very proud that we can now extend the system’s lifetime to 15 years with an experienced local service provider, GWT, and look forward to seeing them deployed in the maritime markets,” Yong Cong Xiong, EVE Energy’s Head of Marine & Port.
