Energy Vault Uses Sodium-Ion to Power AI Data Centers

Energy Vault uses sodium-ion to power AI data centers, paving the way for efficient solutions addressing rising energy demands. As artificial intelligence expands, especially in high-density AI workloads, the power requirements for data centers surge rapidly. Energy Vault Holdings and Peak Energy have joined forces to develop a dedicated storage solution optimized for AI-first data centers and AI Neoclouds.

Innovative Sodium-ion Battery Technology

The new system combines Peak Energy’s sodium-ion battery technology with Energy Vault’s proprietary system design and the advanced Vault OS software controls. This integrated solution stands out for several reasons. Sodium-ion batteries offer higher safety margins and greater reliability than many existing battery energy storage systems. With this, operators can expect improved operational safety, which is crucial for environments demanding uninterrupted power delivery.
Moreover, sodium-ion technology supports faster deployment of storage capacity. Data centers can scale as AI workloads increase. This reduces both complexity and time-to-operation, streamlining infrastructure growth.

Key Benefits for AI Data Centers

One major advantage is the lower capital costs associated with the solution. Sodium-ion chemistry is less reliant on expensive or hard-to-source materials compared to Lithium-ion options. By leveraging domestic manufacturing, especially for the United States, projects using this system may qualify for Domestic Content Investment Tax Credits. These credits provide a notable improvement in project economics compared to lithium-ion and foreign-sourced alternatives.

Underlining the scale of this partnership, Energy Vault has secured 1.5 gigawatt-hours of Peak Energy’s U.S.-manufactured sodium-ion battery systems. This large allocation reflects the trust between the companies and addresses the urgent storage needs faced by AI-first data centers. It also shows a firm commitment to boosting American manufacturing and innovation in sustainable energy technology.

Scalable, Reliable Energy for the AI Sector

Marco Terruzzin, chief revenue officer at Energy Vault, notes the importance of readiness in today’s evolving energy landscape. “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,” he says.

By integrating tailored battery technology with robust system controls, Energy Vault’s solution provides a direct answer to the rising power bottlenecks encountered by AI data center operators. These cloud and data science businesses require both high reliability and scalable energy storage to perform advanced computations, support large-scale data storage, and operate without downtime.

Expanding Access to Global Markets

The partnership doesn’t only focus on North America. Energy Vault has secured exclusive channel partner rights for Peak Energy’s sodium-ion technology in Australia and Japan. Both countries have ambitious growth plans for data intensive infrastructure, reinforcing the global role of sodium-ion battery storage in AI-powered sectors.

The Future of AI and Energy Storage

As data centers continue to fuel digital transformation, energy storage will remain central. Energy Vault and Peak Energy’s collaboration positions sodium-ion batteries as a promising alternative energy storage solution within the AI ecosystem. It enables rapid deployment, enhances operational safety, and improves long-term economic returns.

With over 1.5 gigawatt-hours in secured technology and strategic commitments extending to international markets, Energy Vault is poised to meet the rising demand for sustainable, cost-effective, and reliable power infrastructures for AI applications. The combined expertise of both companies sets a new standard for high-density, power-intensive energy storage worldwide.
