Energy Vault Holdings Inc. (NYSE: NRGV) shares climbed 2.4% on Monday following the announcement of a wide-ranging strategic partnership with Peak Energy to create energy storage products purpose-built for AI workloads.
Under the agreement, the two firms will jointly develop a full-stack storage platform that pairs Peak Energy’s sodium-ion battery hardware with Energy Vault’s digital integration layer aimed at AI infrastructure. As part of the arrangement, Energy Vault has secured an initial offtake contract for 1.5 GWh of Peak’s sodium-ion batteries, all of which will be manufactured in the United States. The U.S.-based supply is intended to provide greater supply chain security and to make the batteries eligible for Domestic Content tax credits.
The partners said they will introduce a dedicated energy storage architecture targeted at AI Neoclouds and operators building AI-first data centers. The announcement notes that conventional battery systems are not designed to accommodate the extreme power and performance profiles generated by AI workloads, and that the new platform seeks to address those shortcomings.
Energy Vault emphasized the integration aspect of the deal. All Peak Energy systems deployed under this agreement will be incorporated into Vault OS, Energy Vault’s proprietary energy management system. Vault OS will be responsible for managing the batteries’ operating characteristics, optimizing dispatch schedules, and extending the operating life of deployed assets.
The partnership also grants Energy Vault exclusive channel partner rights for Peak Energy’s sodium-ion technology in Australia and Japan, making Energy Vault the sole provider of that technology in those markets under the terms of the agreement. The companies say the commercial arrangement couples Peak’s battery chemistry with Energy Vault’s software and systems integration expertise.
Commenting on the collaboration, Marco Terruzzin, Chief Revenue at Energy Vault, said: "The rapid growth of AI is exposing fundamental limitations in conventional power infrastructure. This solution enables faster deployment, lower cost, and improved safety by combining Energy Vault’s integration platform with Peak’s sodium-ion technology." The quote highlights the partnership’s stated goal of speeding deployments while reducing cost and improving safety.
The announcement centers on industrial-scale deployments for AI-focused compute environments and underscores an integrated approach - combining hardware supply commitments, software integration, and regional channel exclusivity - to address what the companies describe as gaps in existing power infrastructure for AI workloads.
Clear summary: Energy Vault and Peak Energy will co-develop a full-stack, AI-specific energy storage platform incorporating 1.5 GWh of U.S.-made sodium-ion batteries, exclusive channel rights in Australia and Japan for Energy Vault, and full integration of deployed systems into Vault OS to manage operations, dispatch, and asset longevity.
