Energy Vault® develops and deploys utility-scale energy storage solutions designed to transform the world's approach to sustainable energy storage. The company's offerings include proprietary gravity, battery, and green hydrogen energy storage hardware technologies, supported by the EVS™ technology-agnostic energy management system software and integration platform. Energy Vault’s innovative technology portfolio uniquely delivers customized short-and-long-duration energy storage solutions to help customers significantly reduce levelized energy costs while maintaining power reliability. Utilizing eco-friendly materials with the ability to integrate waste materials for beneficial reuse, EVx™ gravity energy storage technology is facilitating the shift to a circular economy while accelerating the global clean energy transition.


Energy Vault® LDES solutions are based on proprietary gravity energy technology and ideally deployed for use cases requiring 4 or more hours of storage capacity. Energy Vault® Gravity Energy Storage System (GESS) solutions utilize a mechanical process of lifting and lowering composite blocks to store and dispatch electrical energy. Our proprietary technology offers LDES at a cost-competitive price to support grid reliability and enable renewable energy integration. Energy Vault® GESS solutions can be deployed as stand-alone storage or paired with generation in a hybrid configuration.

Short Duration

Energy Vault® SDES solutions are designed for use cases requiring up to 4 hours of storage capacity and are enabled by our technology-neutral software platform. Energy Vault® SDES solutions integrate various storage technologies including a lithium-ion based battery energy storage system (BESS). Optimized for industrial and utility-scale deployments, Energy Vault® BESS proprietary AC block architecture is designed to maximize energy density with a unique modular form factor selected to streamline site installation and deployment.


Energy Vault® technology-neutral software solutions are designed to support real-time remote monitoring, operational control, and AI-enabled dispatch optimization across an array of energy storage and energy generation assets. At the site level, the Energy Vault® Energy Management System (EMS) coordinates all equipment controls to provide a cohesive operational plant view and to facilitate continuous data collection and analysis. Secure cloud-based monitoring and performance optimization can be applied behind the meter at a single site, as well as across an asset portfolio of multiple sites to enable fleet-wide control. Integrated smart bidding software utilizes machine learning algorithms to match node-specific data with real-time weather and asset performance information to generate tailored load, generation, dispatch, and price forecasting across all assets.
