erneo advanced CAES energy storage


Adele was a CAES project initiated 2012 by RWE power in Germany. 

The compressed air is stored in 2 salt caverns at about 150 bar. During the compression of the air from 1 bar to 150 bar the tempearture rises to about 600 °C. The heat was planned to be stored in large concrete heat storages and was supposed to be fed back to the gas stream during discharge of the storage.
