{City}, {State/Province} — February 9, 2026 — Leads & Copy —
Energy Vault Holdings, Inc. (NYSE: NRGV) and Peak Energy have announced a strategic partnership to develop energy storage for AI infrastructure.
The partnership will focus on a co-developed energy storage architecture designed for AI Neoclouds and AI-first data center operators. According to the companies, traditional battery systems are not suited for the power demands of AI training and inference workloads.
The new architecture combines Peak Energy’s sodium-ion energy storage technology with Energy Vault’s system design and Vault OS™ software controls. The companies say this will deliver faster deployment, lower capital cost, and enhanced operational safety. Peak Energy’s sodium-ion energy storage technology enables higher safety and reliability than conventional BESS.
Energy Vault has secured 1.5 gigawatt-hours (GWh) of Peak Energy’s U.S.-manufactured sodium-ion battery systems through a definitive supply agreement.
Energy Vault has also secured exclusive channel partner rights for Peak Energy’s sodium-ion technology in Australia and Japan.
The integrated solution is exclusive to Energy Vault and serves as a differentiator for the company’s modular “powered shell” data center offering, which the companies say will provide simplified electrical design, reduced reliance on traditional UPS systems, lower cooling requirements, and improved handling of high-volatility AI compute loads.
Marco Terruzzin, Chief Revenue at Energy Vault, stated that the solution enables faster deployment, lower cost, and improved safety by combining Energy Vault’s integration platform with Peak’s sodium-ion technology.
Landon Mossburg, Chief Executive Officer at Peak Energy, said that the partnership confirms that Peak technology is at the center of meeting AI energy needs.
According to the release, all Peak Energy systems deployed under the agreement will be fully integrated into Vault OS™, Energy Vault’s energy management system. Vault OS™ will manage the operating characteristics of sodium-ion batteries, optimize dispatch, extend asset life, and maintain Energy Vault’s operational control of the systems.
The companies expect that by securing domestic supply, Energy Vault projects across both grid-scale BESS and AI infrastructure will qualify for Domestic Content Investment Tax Credits (ITC).
Founded in 2023, Peak Energy is a U.S.-based company developing low-cost, giga-scale energy storage technology.
Energy Vault develops, deploys, and operates utility-scale energy storage solutions.
