Compressed air energy storage (CAES)

and for most CAES systems that have been considered seriously, r is set between about 20 and 200. When air is compressed, it tends to become warmer. If no heat is allowed to enter or leave the air during compression, the temperature of the air after compression is related to that before compression according to: (6.5) (T 1 / T 0) = (p 1 / p …
