SYSTEM AND METHOD OF STORING AND RECOVERING ENERGY BY MEANS OF COMPRESSED GAS, COMPRISING A MIXED LAYER OF PRESTRESSED CONCRETE

摘要

- The invention relates to a container for storing a pressurised fluid such as compressed air. In particular, the container is in the form of at least one tube formed from an arrangement of concentric layers (C1, C2, C3, C4), this arrangement comprising, from the inside to the outside of the tube, an inner layer made of concrete (C1), a layer (C2) made of steel of thickness E, at least one layer (C3) made from a coil of steel wires (C3'') on a concrete sublayer (C3'), and an outer layer (C4) for protecting said wires from physical and/or chemical damage, and wherein the wires are subjected to circumferential tensile prestressing, at least the thickness E and/or the prestressing being dimensioned so as to withstand said pressure. - The invention is particularly applicable to storing and recovering energy by means of compressed air.
