Energy Vault Holdings is teaming up with Peak Energy to deliver a dedicated energy storage architecture built for AI Neoclouds and AI-first data center operators, betting that sodium-ion batteries can solve some of the sector’s emerging power bottlenecks. 

The new architecture combines Peak Energy’s sodium-ion battery technology, which the companies say offers higher safety and reliability than conventional battery energy storage systems, with Energy Vault’s proprietary system design and Vault OS software controls. The integrated solution is designed to enable faster deployment, lower capital costs, and enhanced operational safety for high-density, power-intensive AI workloads. 

“The rapid growth of AI is exposing fundamental limitations in conventional power infrastructure,” said Marco Terruzzin, chief revenue officer 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.” 

As part of the partnership, Energy Vault has secured 1.5 gigawatt-hours of Peak Energy’s U.S.-manufactured sodium-ion battery systems. The companies said projects across both grid-scale battery storage and AI infrastructure are expected to qualify for Domestic Content Investment Tax Credits, improving project economics relative to lithium-ion and foreign-sourced alternatives. 

Energy Vault also secured exclusive channel partner rights for Peak Energy’s sodium-ion technology in Australia and Japan.
