Abstract
(EN)
The invention relates to an electricity generation system (1) comprising: at least one compressor (10) that delivers a flow of working fluid with a pressure greater than atmospheric pressure; at least two high-pressure recipients (20a, 20b) that store the working fluid delivered by the compressor (10); at least two solar tanks (30a, 30b) that receive the working fluid from the high-pressure recipients (20a, 20b); at least one turbine (40) that receives a flow of working fluid from the solar tanks (30a, 30b) to generate electricity; a set of valves (50, 51, 52, 53, 54, 55, 56) arranged to control the flow of working fluid from the at least one compressor (10) to the at least one turbine (40), controlling the inlet and outlet of working fluid into the respective high-pressure recipients (20a, 20b) and solar tanks (30a, 30b); at least one heat source that delivers heat energy to the solar tanks (30a, 30b); and at least two heat exchangers (32a, 32b) disposed in each of the solar tanks (30a, 30b), respectively, to transmit the heat energy into the tanks (30a, 30b) to increase the pressure and temperature of the working fluid contained therein. The invention also relates to electricity generation.
