Problem
Renewable energy sources like solar and wind are intermittent, creating a need for large-scale, long-duration energy storage to ensure a continuous and reliable power supply. Existing energy storage solutions often lack the capacity and duration necessary to fully support a grid powered entirely by renewables.
Solution
TerraStor develops grid-scale energy storage systems using advanced compressed air energy storage (ACAES) technology. This approach utilizes natural geological formations and ambient air to create large mechanical batteries, providing a clean, simple, and economic storage solution. TerraStor's systems target projects that can deliver at least 100 megawatts of power and one gigawatt-hour of energy storage, enabling electrical grids to achieve 100% renewable penetration. By leveraging existing technology and working with natural resources, TerraStor aims to provide low-cost, highly-responsive, extra-long duration energy storage for a carbon-free future.
Target Audience
TerraStor's primary customers are utility companies and grid operators seeking to integrate large amounts of renewable energy and ensure grid stability.
