Energy Vault Holdings, Inc. (NYSE: NRGV) and Peak Energy announced a strategic partnership that will develop a sodium‑ion battery platform tailored for AI‑first data‑center operators. The collaboration includes a 1.5 GWh supply agreement that will accelerate global deployment and reduce costs for both companies.
The partnership positions Energy Vault to capture a growing niche in the data‑center storage market, where demand for reliable, long‑duration power is rising alongside the expansion of artificial‑intelligence workloads. By combining Energy Vault’s gravity‑based and software expertise with Peak Energy’s first‑in‑the‑U.S. sodium‑ion technology, the two firms aim to deliver a high‑efficiency, cost‑effective storage platform that can be rapidly deployed in data‑center sites worldwide. The U.S. manufacturing base also makes the project eligible for Domestic Content Investment Tax Credits, a key financial incentive for large‑scale deployments.
Energy Vault’s financial profile remains challenging. The company is currently unprofitable and reported a revenue decline in its most recent quarter, with Q3 2025 revenue at $33.3 million versus a $48.99 million consensus estimate. Despite this, the 1.5 GWh supply agreement represents a new recurring revenue stream that could help stabilize cash flow and improve margin profiles as the company scales its “Own & Operate” asset‑management strategy. Analysts note that while the partnership is a material win, Energy Vault’s broader profitability trajectory remains uncertain.
Marco Terruzzin, Chief Revenue Officer at Energy Vault, said the deal “addresses the fundamental limitations of conventional power infrastructure for AI workloads. By integrating our Vault OS with Peak’s sodium‑ion technology, we can deliver faster deployment, lower cost, and improved safety.” Landon Mossburg, CEO of Peak Energy, added that the partnership “lowers the cost of energy for data centers and offers the fastest path to grid‑connected storage.”
The partnership is part of Energy Vault’s broader strategy to diversify beyond gravity‑based storage. The company has also secured exclusive regional channel rights for Peak Energy’s technology in Australia and Japan, expanding its global reach in key markets. While the company’s guidance for the full year remains unchanged, the new contract signals confidence in its technology roadmap and a potential shift toward higher‑margin, high‑growth segments.
Overall, the collaboration marks a significant step for Energy Vault as it seeks to broaden its product portfolio and tap into the rapidly expanding AI data‑center market. The partnership’s domestic manufacturing advantage and tax‑credit eligibility add financial upside, while the company’s current profitability challenges underscore the need for continued execution and cost discipline.
