Energy Vault Holdings Inc. (NYSE: NRGV) has announced a major strategic development agreement with Peak Energy, marking a significant step toward building purpose-built energy storage solutions for AI-centric computing infrastructure. The partnership, which includes a 1.5 gigawatt-hour (GWh) supply agreement for Peak’s U.S.-manufactured sodium-ion battery systems, is designed to accelerate global deployment, cut costs, and enhance supply chain security for next-generation data centers and grid-scale storage projects.

⚡ Meeting AI’s Power Demands with Tailored Storage
As AI workloads — especially training and inference for large models — grow more power-intensive, conventional battery energy storage systems (BESS) optimized for steady grid loads face limitations in meeting the volatile and high-density demands typical of AI data centers. Under the agreement, Energy Vault and Peak Energy will co-develop a full-stack storage architecture that blends Peak’s sodium-ion battery technology with Energy Vault’s proprietary design and Vault OS™ software controls to deliver a safer, more efficient, and lower-cost solution tailored specifically for AI-first infrastructure.
Energy Vault’s platform is intended to integrate smoothly with its modular “powered shell” data center offerings by simplifying electrical design, reducing dependence on traditional UPS systems, cutting cooling demands, and better handling the rapid load changes seen in AI operations.
🔋 1.5 GWh Supply Agreement and U.S. Manufacturing Advantage
A cornerstone of the deal is a definitive 1.5 GWh offtake agreement securing Peak Energy’s sodium-ion battery systems — all manufactured in the United States. This domestic supply not only strengthens resilience in Energy Vault’s supply chain but also positions qualifying projects to benefit from Domestic Content Investment Tax Credits (ITC), enhancing the economics of deploying energy storage at scale compared with foreign-sourced alternatives.
“Lowering the cost of energy is essential for winning the AI race,” said Peak Energy CEO Landon Mossburg, highlighting sodium-ion’s cost advantages and suitability for AI power needs.
Moreover, all systems supplied through this partnership will be fully integrated with Energy Vault’s Vault OS™ energy management system, which is designed to optimize battery performance, extend asset life, and maintain centralized operational control.
🌍 Exclusive Global Channel Rights and Expansion
Beyond the U.S. supply deal, Energy Vault also secured exclusive regional channel rights for Peak Energy’s technology in Australia and Japan — two key markets with growing energy storage demand and strategic importance for global infrastructure development. These arrangements expand the partnership’s global reach and help position Energy Vault as a leading provider of specialized storage solutions beyond North America.
📈 Strategic Importance for Energy and AI Infrastructure
This agreement comes at a time when the intersection of AI and energy infrastructure is becoming increasingly critical. Powering AI workloads not only requires massive capacity but also flexibility to respond to fast-changing loads — needs that traditional lithium-ion solutions sometimes struggle to meet cost-effectively and safely. Sodium-ion technologies — known for enhanced safety, reduced reliance on rare materials, and strong manufacturing scalability — offer a compelling alternative for such applications.
By marrying this chemistry with Energy Vault’s digital management stack, the companies aim to tackle AI infrastructure power challenges and support data centers that must operate reliably while optimizing for cost and energy efficiency.
