Is a liquid air energy storage system suitable for thermal storage?
A novel liquid air energy storage (LAES) system using packed beds for thermal storage was investigated and analyzed by Peng et al. . A mathematical model was developed to explore the impact of various parameters on the performance of the system.
How to reuse temperature related exergy of compressed air?
The simplest way to reuse the temperature related part of the exergy of the compressed air is to store the hot air itself inside a combined thermal energy and compressed air storage volume (Fig. 18a). Due to the high temperatures already reached at rather low pressure ratios these concepts require highly temperature resistant storage volumes.
