The Hydrostor Terra™ system utilizes a proprietary isobaric purpose-built underground cavern for air storage, which can be deployed at any site within proximity to a body of water, including inner-city and urban areas. Terra™ utilizes hydrostatic pressure from a water-filled shaft to maintain an isobaric (constant pressure) system during charge and discharge, significantly reducing the cavern size required as compared to traditional CAES systems. When charging, compressed air is piped from the surface into the purpose-built accumulator, displacing water up the shaft and back to its source. Conversely, when the system discharges, compressed air flows back up to the mechanical equipment while gravity forces water to flow into the accumulator, displacing the air.Hydrostor Terra Brochure
The Hydrostor Marine system utilizes HydroPod, a rigid-walled accumulator structure designed for quick and simple underwater installation at depths of 150+ meters. Hydrostor Marine facilitates bulk storage where deep water is located close to shore. This system is connected via drilled air communication pipe from shore, and utilizes hydrostatic pressure found at depth to maintain an isobaric (constant pressure) system during charge and discharge. Compressed air is pumped into the HydroPods displacing water in the accumulators during charge, with water displacing the air during discharge.Hydrostor Marine Brochure
Utilizing an existing cavern such as a salt dome or existing mine, Hydrostor surface equipment flows compressed air into and out of the cavity, steadily building pressure used for storage. This variable pressure system can repurpose existing infrastructure in stabilizing the grid.
Hydrostor systems use utility-grade, bankable Tier 1 OEM compressors and expanders, proven over decades of operation in the power sector. Our systems can be operated with charge rate, discharge rate, and storage capacity set independently, providing maximum design and operational flexibility to suit the application. As an example, our systems can charge an entire night’s worth of solar power during the day, or take full advantage of negative power pricing by quickly charging in a few short hours, then slowly delivering that power over many hours.
Unlike traditional CAES systems, which rely on natural gas to generate heat required during operation, Hydrostor utilizes a patented adiabatic thermal management system to efficiently recycle heat generated during compression for later use during generation, making it truly emission-free. The proprietary sizing, material selection, configuration, and execution of Hydrostor’s Thermal Store technology increases round-trip efficiency. Eliminating the need for fossil fuel burning during the generation phase significantly reduces operational costs and eliminates harmful emissions.
