Cryogenic energy storage LNG is firstly pumped to 30 MPa (stream L2) and then transfers its cold energy with air in HEX-6 to HEX-1 successively resulting in the liquefaction of air after leaving HEX-6 (stream A12). Then, the LNG (stream L8 with a temperature around -56 °C) from HEX-1 is used to condense the mixed working fluid

Therefore, the average energy storage capacity defined as the amount of heat stored by unit time is the lowest in concentric HEX. The evaluated average energy storage for hairpin HEX and concentric HEX is 450 and 140 W, respectively. Therefore, the average energy storage capacity is 3.25 times higher for hairpin HEX compared to

Renewables should become more continuously available, reliable and cost-efficient to manage the challenges caused by the energy transition. Thus, analytic and numerical investigations for the layout of a pilot plant of a concept called Fluidisation-Based Particle Thermal Energy Storage (FP-TES)—a highly flexible, short- to long-term fluidised bed
The proposed concept derives from A-CAES with the difference being it enables producing heating and cooling energy. As well as A-CAES, during the charge phase ambient air is compressed via multistage compressors. The compressed air is cooled after each compression stage in a heat exchanger (HEX) by thermal energy storage
