Title: COMBINED CYCLE CAES TECHNOLOGY (CCC)
Abstract:
The invention relates to a system which stores energy on the basis of the compression of atmospheric air and the confinement thereof in tanks or caverns, which combines the thermodynamic cycle followed by atmospheric air (Brayton cycle) with another thermodynamic cycle, which an auxiliary fluid enclosed in the cavern inside a membrane is made to follow, followed by two sections of a Rankine cycle, one during the air compression process and entry of air into the cavern and the other during the exit of air and turbinated flow, taking advantage of the residual heat of the exhaust gases from the compressed air turbine as a source of heat of the Rankine auxiliary fluid cycle and being able to utilize the tanks or caverns to carry out heating therein of the compressed air and/or the auxiliary fluid at a constant volume.
