Underwater Compressed Air Electrical Storage

The Hydrostor system efficiently converts electrical energy to compressed air via an advanced adiabatic compression system. This air is then sent to a series of accumulators located 50-500 meters below the surface of a body of water. Once in the accumulators, the energy can be stored until needed by the grid. When the energy is to be delivered, the weight of the water pushes the air back to the surface where our system directs it through an expander turning a generator and efficiently converting the energy back into electricity for the grid and completing the storage cycle.

This rapidly deployed, low cost system uses non-toxic substances with minimal environmental disturbances while offering 70% round trip efficiencies without the need for fossil fuel.
