Key Highlights
- Energy Vault has partnered with Peak Energy to develop AI-focused energy storage solutions.
- The collaboration includes a 1.5 GWh offtake agreement for U.S.-made sodium-ion batteries.
- The solution targets AI Neoclouds and AI-first data centre operators. The partnership supports domestic sourcing to qualify for U.S. investment tax credits.
Energy Vault Holdings Inc. has entered into a strategic partnership with Peak Energy to jointly develop energy storage systems tailored specifically for AI-driven data centre infrastructure. As part of the agreement, Energy Vault has secured an initial 1.5 gigawatt-hour (GWh) offtake of Peak Energy’s U.S.-manufactured sodium-ion battery technology.
The collaboration reflects growing pressure on traditional power infrastructure as artificial intelligence workloads drive unprecedented demand for reliable, scalable, and cost-effective energy solutions.
Building Storage for AI-First Data Centres
The companies plan to co-develop a next-generation energy storage architecture designed for AI Neoclouds and AI-first data centre operators. The system will integrate Peak Energy’s sodium-ion battery technology with Energy Vault’s proprietary system design and Vault OS software controls.
This integrated solution will be deployed exclusively within Energy Vault’s modular data centre offering, positioning the company to address the unique power-density, safety, and deployment challenges associated with AI infrastructure.
“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.”
Securing Domestic Supply and Tax Credit Eligibility
In addition to the technology collaboration, Energy Vault has signed a definitive supply agreement for 1.5 GWh of Peak Energy’s sodium-ion battery systems. By locking in domestic supply, the company ensures its battery energy storage systems (BESS) and AI infrastructure projects can qualify for U.S. Domestic Content Investment Tax Credits (ITC).
This move aligns with broader industry efforts to strengthen local supply chains while reducing exposure to international battery sourcing risks.
Expanding Global Reach
Beyond the U.S. market, Energy Vault has also secured exclusive channel partner rights for Peak Energy’s sodium-ion technology in Australia and Japan. The agreement positions Energy Vault to extend its AI-focused energy storage solutions into key international markets where demand for data centre capacity continues to accelerate.
Peak Energy, founded in 2023, focuses on grid-scale sodium-ion battery energy storage systems designed as an alternative to lithium-based technologies, offering potential advantages in cost, safety, and material availability.
