Joint Development of AI-Dedicated Storage: The companies will co-develop a full-stack storage platform—combining Peak Energy’s sodium-ion batteries with Energy Vault’s proprietary digital stack—dedicated to Energy Vault’s AI infrastructure portfolio. This solution accelerates deployment, enhances safety, and reduces costs by eliminating complex legacy systems.
Strategic Supply Chain Advantage: Energy Vault secures an initial 1.5 GWh offtake of Peak Energy’s U.S.-manufactured sodium-ion batteries, locking in supply chain security and Domestic Content tax credit eligibility to deliver superior unit economics for BESS and AI infra projects.
Global Market Expansion: Energy Vault secures exclusive regional channel rights for Peak Energy technology in the APAC region, expanding the companies’ combined footprint in key high-growth international markets.
WESTLAKE VILLAGE, Calif. & BROOMFIELD, Colo.--(BUSINESS WIRE)--
Energy Vault Holdings, Inc. (NYSE: NRGV) (“Energy Vault” or “the Company”), a leader in sustainable grid-scale energy storage and AI power infrastructure, and Peak Energy (“Peak”), the first American manufacturer of sodium-ion energy storage systems, today announced a comprehensive strategic partnership.
Purpose-Built Energy Storage for AI Infrastructure
The partnership includes the launch of a co-developed, dedicated energy storage architecture designed specifically for AI Neoclouds and AI-first data center operators. Traditional battery systems are optimized for steady grid loads and are not well suited to the extreme and volatile power demands created by AI training and inference workloads.
The new architecture combines Peak Energy’s sodium-ion energy storage technology that enables much higher safety and reliability than conventional BESS with Energy Vault’s proprietary system design and Vault OS™ software controls to deliver faster deployment, lower capital cost, and enhanced operational safety.
The integrated solution is exclusive to Energy Vault and serves as a key differentiator for the Company’s modular “powered shell” data center offering. Benefits include simplified electrical design, reduced reliance on traditional UPS systems, lower cooling requirements, and improved handling of high-volatility AI compute loads.
“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.”
1.5 GWh U.S. Supply Agreement and Domestic Content Advantage
Energy Vault has executed a definitive supply agreement securing 1.5 gigawatt-hours (GWh) of Peak Energy’s U.S.-manufactured sodium-ion battery systems.
By locking in domestic supply, Energy Vault projects across both grid-scale BESS and AI infrastructure are expected to qualify for Domestic Content Investment Tax Credits (ITC), providing a more attractive economic profile relative to lithium-ion alternatives and foreign-sourced solutions.
“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 centers on the grid,” said Landon Mossburg, Chief Executive Officer at Peak Energy. “This partnership confirms that Peak technology is at the center of meeting AI energy needs today and into the future.”
Vault OS™ Integration
All Peak Energy systems deployed under the agreement will be fully integrated into Vault OS™, Energy Vault’s proprietary, technology-agnostic energy management system. Vault OS™ will manage the unique operating characteristics of sodium-ion batteries, optimize dispatch, extend asset life, and maintain Energy Vault’s operational control of the systems.
Exclusive Rights in Australia and Japan
Energy Vault has also secured exclusive channel partner rights for Peak Energy’s sodium-ion technology in Australia and Japan. These exclusive rights position Energy Vault as the sole provider of this solution in two of the world’s most constrained and high-value energy markets, expanding the partnership’s global reach.
