Operating performance of a Joule-Brayton pumped thermal energy storage system integrated with a concentrated solar power plant.

[EN]The expected performance of an innovative Pumped Thermal Energy Storage (PTES) system based on a closedloop Brayton-Joule cycle and integrated with a Concentrated Solar Power (CSP) plant are analysed in this study. The integrated PTES–CSP plant includes five machines (two compressors and three t...
