Our advanced compressed air energy storage (A-CAES) system is a cost-effective, emission-free solution capable of delivering hundreds of megawatts and four to 24 hours of long-duration bulk energy storage.
It consists of three main components: the plant, a closed-loop water reservoir, and subsurface infrastructure.
The system utilizes off-peak or surplus energy to run a compressor, capturing heat generated during compression for later reuse.
The compressed air is stored underground in purpose-built caverns, hydrostatically compensated and capable of delivering power on demand.
With no fuel costs or hazardous chemicals, the system offers low environmental impact and reliable operation for up to 50 years.
It provides various grid support services and enhances round-trip efficiency through its adiabatic process, making it suitable for a wide range of applications, including renewable integration and industrial operations.
