Advanced Compressed Air Energy Storage
Advanced Compressed Air Energy Storage
Hydrostatic pressure naturally created by water depth makes the Hydrostor Solution one of the cleanest, most economical energy storage solutions available today.
The Hydrostor Technology
The Hydrostor solution is true bulk energy storage that addresses the issues of renewable intermittency, grid load balancing, reserve capacity and peak shaving. Hydrostor’s Advanced-Compressed Air Energy Storage (CAES) technology can leverage both in-ground (e.g., salt dome, mines) and underwater storage solutions.
Utilizing state of the art mechanical and electrical components from some of the world’s leading manufacturers,
our clients receive the comfort and peace of mind that the Hydrostor system will perform admirably for the life of the equipment and is backed by a global service network.
Our projects use drilling systems that minimize environmental disturbance and nearly eliminate the need for off-shore construction, as well as a thermal management system allowing superior capture of heat driving our efficiency even higher.

How it worksHydrostor’s Adiabatic Compressed Air Energy Storage solution operates by using electricity to run an air compressor which converts the electrical energy into compressed air. Heat from compression is captured during this step and stored to be used during generation, thus increasing the system efficiency. The system also has the flexibility to incorporate additional heat to further increase roundtrip efficiency. The compressed air stream is pressurized to the same pressure found at depth where the accumulators are located.
The air displaces the water in the accumulators and is held until electricity is needed by the consumer.
To satisfy the need for electricity the Hydrostor system reverses the air flow allowing the weight of the water to force the air back to surface under pressure. At surface the stored heat is added back into the air stream and the heated air travels to an expander which drives a generator efficiently converting the energy in the air back into electricity for the consumer.
