Energy Vault has signed a comprehensive strategic partnership with U.S.-based Peak Energy including the development of a purpose-built energy storage solution for AI infrastructure.
The companies will co-develop a full-stack storage platform, combining Peak Energy’s sodium-ion batteries with Energy Vault’s proprietary digital stack.
The energy storage architecture will be designed specifically for AI Neoclouds and AI-first data centre operators.
AI data centres need different energy storage from traditional battery systems, which are generally optimised for steady grid loads and not suited to the extreme and volatile power demands created by AI training and inference workloads.
“The rapid growth of AI is exposing fundamental limitations in conventional power infrastructure,” said Marco Terruzzin, Chief Revenue at Energy Vault.
“This solution enables faster deployment, lower cost, and improved safety by combining Energy Vault’s integration platform with Peak’s sodium-ion technology.”
Energy Vault also signed a definitive supply agreement securing 1.5 gigawatt-hours (GWh) of Peak Energy’s U.S.-manufactured sodium-ion battery systems.
The supply agreement secures supply chain security and domestic content tax credit eligibility to deliver superior unit economics for battery energy storage systems and AI infrastructure projects.
Landon Mossburg, CEO at Peak Energy, said: “Lowering the cost of energy is essential for winning the AI race and Peak’s proprietary sodium-ion energy storage systems offer the lowest cost and fastest way to get data centres on the grid.”
Energy Vault has also secured exclusive channel partner rights for Peak Energy’s sodium-ion technology in Australia and Japan, two of the world’s most constrained and high-value energy markets, expanding the partnership’s global reach.
