 Long-term prospects for compressed air storageI. Glendenning Applied Energy, 1976, vol. 2, issue 1, 39-56 Abstract: The compressed air storage (CAS) concept has been reviewed in the light of the long-term requirement for energy storage to effect load following in a predominantly nuclear generating system. This requirement would eventually lead to the operation of storage plant on a daily cycle of storing energy for 6-8 h and generating for 12-16 h. Conventional CAS schemes, typified by the Nordwestdeutchen Kraftwerke (NWK) installation in West Germany, are shown to be incapable of fulfilling this duty on merit. The basic concept is then re-examined and a novel development is proposed which, by using uncooled compressors and conserving the compression energy, constitutes a true energy storage scheme requiring no fuel other than the off-peak energy taken from the electrical grid. The efficiency and other performance characteristics of this proposal are discussed. The capital cost of an 8 GWh storage scheme is tentatively put at £125-175/kW (at 1974 price levels), depending on the air store construction, well within the £200/kW cost target which storage plant would need to meet to be of interest for storing off-peak nuclear power by the end of the present century. It is concluded that, once developed, CAS schemes which incorporate heat storage could provide an attractive method for storing off-peak electricity.
