Abstract

The present invention relates to cryogenic energy storage systems for storing using high-grade heat-of-compression. The system includes a liquefaction sub-system (100) and thermal energy storage device (TESD) (300). The liquefaction sub-system (100) includes a first compressor (102), a first and second heat exchanger (104, 117) and second compressor (114). The first and second heat exchangers (104, 117) are configured to transfer the high-grade heat of compression from the first and second compressors (102, 114) respectively to the TESD (300) via a closed circuit using a heat transfer fluid (HTF). A third compressor (124) compresses the HTF and at least a portion of the high-grade heat of compression from the third compressor (124) is transferred to the TESD (300). Further systems including power recovery sub-systems (400) use compressors (124) and expanders (122). The present disclosure also relates to methods of heat-of-compression storage in cryogenic energy storage systems.
