Due to the intensive development of renewable energy, producing electricity in an irregular and unpredictable way, storage looks set to play an increasingly important role in the energy system. There are only two systems currently used to store electricity on a large scale: pumped storage and compressed air energy storage (CAES), whose respective special geographical requirements mean it is hard to find the right place to implement them in practical terms. This paper takes a comparative look at ‘geography-free’ liquid air energy storage (LAES) vis-à-vis systems based on compressed air, including balance calculations for selected configurations. A comprehensive energy and exergy analysis was conducted together with a comparison of storage volumes for the systems under consideration.
