Off-peak or surplus electricity from the grid or a renewable source is used to run a compressor and produce heated compressed air.

Compress Air 
Using Electricity

Air is stored in a purpose-built underground cavity, where hydrostatic compensation maintains the system at a constant pressure.

Store
Compressed Air

Heat is extracted from the air stream and stored inside a proprietary thermal store.

Capture Heat in

Thermal Store

Hydrostatic pressure forces air to the surface, where it is re-heated by the thermal store and expanded through a turbine to generate electricity on demand.

Convert Compressed Air

to Electricity On Demand

Low Cost

​

Lowest installed cost per kilowatt hour (kWh) for large-scale, long duration energy storage. 30+ year system life with unlimited cycling and no replacement required.

Ancillary Services

​

Supports electrical grid stability and resiliency, with the system's synchronous generation providing rotational inertia. Delivers VAR support, spinning reserve, black start and frequency response.

Flexible Siting

Sites where grid requires it using a  proprietary, purpose-built air storage cavern. No toxic materials or thermal impacts on environment. Ideal for high-value grid applications near load, with low noise, small footprint. 

Customized System Design

System design optimized to match client requirements, with independent settings for charge, discharge and storage capacity.

Emission Free

​

Increased efficiency, lower operating costs, and no hazardous chemicals or use of fossil fuels with Hydrostor's patented adiabatic thermal management system.

Proven Solution

​

Warrantied and guaranteed systems using industry-proven mechanical equipment from Tier 1 OEM suppliers paired with well-tested planning and engineering expertise derived from analogous projects.
