We develop highly efficient advanced compressed air energy storage (ACAES) systems. ACAES systems are large, mechanical batteries that look like a power plant at surface and are sited over a geologically-based storage cavern, such as one created in a salt dome. ACAES plants offer 100+ MW in power output and 8-24+ hours in storage duration.

ACAES uses existing geology so we don’t have to disturb the land or build massive containers. ACAES can scale storage duration and maintain the same power capacity at zero incremental cost due to the nature of certain geologic formations that could serve as the storage medium.
Our deep understanding of subsurface geology and reservoir engineering affords us creative and proprietary insights in the design and deployment of next-generation ACAES systems that maximize the natural characteristics of local geology.
Each system supports hundreds of megawatts of renewable energy and grid stability services to enable 100% renewable energy adoption
Each MWh of energy stored eliminates half a ton of CO2 emissions from the electrical grid
Facilities have small surface footprint (ft2 / MWh) and can be sited on brownfield oil and gas locations
