Energy Vault (NYSE:NRGV) is a global energy storage technology company specializing in long-duration, gravity-based energy storage solutions. Founded in 2017 and headquartered in Lugano, Switzerland, the firm has developed a modular system that uses large composite blocks and a proprietary crane system to convert excess renewable energy into gravitational potential energy. When energy demand peaks, the system lowers the blocks to generate electricity through regenerative braking, offering a dispatchable, carbon-free alternative to traditional battery storage.
The company’s flagship product line, EVx, integrates advanced materials science, software-driven controls and artificial intelligence to optimize charge and discharge cycles. Composite blocks—manufactured from a blend of local soils, recycled industrial byproducts and construction waste—are arranged and stacked by electric-powered cranes under computer control. This approach delivers a low-cost, scalable storage solution capable of delivering multi-hour discharge durations suitable for utility-scale and commercial microgrid applications.
Energy Vault provides end-to-end services including project siting, system design, installation and ongoing operations and maintenance. The company has secured pilot and commercial projects across Europe, South America, the Middle East and North America, collaborating with utilities, independent power producers and renewable energy developers. By partnering with regional stakeholders, Energy Vault aims to tailor its systems to local grid requirements and resource availability, supporting the integration of wind, solar and other intermittent renewables.
In April 2022, Energy Vault completed a merger with a special purpose acquisition company (SPAC) to become publicly traded on the New York Stock Exchange under the ticker NRGV. The leadership team comprises veterans of energy storage, renewable development and automation industries, focusing on driving commercial deployments and further advancing system performance. With a growing international footprint and a patented approach to gravity storage, Energy Vault positions itself as a key player in the transition to reliable, low-carbon power systems.
