Compressed Air Energy Storage (CAES) is a promising technology for many countries across the globe that have abundant geological resources suitable for salt-cavern based bulk-scale storage.
Additional volume for air storage in CAES could compensate the reduced electrical cycle efficiency, as the energy storage cost in $/kWh is low. The effect of the heat losses in thermal energy storage will be considered in future studies. A.4. Power flow modelling and optimisation
Taking the UK power system as a case study, this paper presents an assessment of geological resources for bulk-scale compressed air energy storage (CAES), and an optimal planning framework for CAES in combination with solar and wind to replace fossil fuels in the Exergy storage capacity contributed by the enhanced pressure
CAES has low storage costs per unit energy (i.e. $/kWh) and negligible self-discharging, making it suitable for large-scale long-duration storage, which could significantly outperform electrochemical storage such as lead-acid batteries or lithium batteries for maximising the value of bulk-scale storage-integrated renewable generation .
When the storage capacities, power capacities, and the dispatching patterns of CAES and gas are optimised, the system cost is estimated using Eq. (6) rather than Eq. (5). In the power flow optimisation, the annualised fixed cost per power capacity and energy capacity of CAES are $871/MW and $39/MWh respectively .
