Underground compressed air
Compressed air energy storage
Northern Germany’s widespread salt domes offer ideal conditions for constructing the large caverns for compressed air energy storage power plants. Storage caverns with volumes surpassing 500,000 m3 have long been used to store natural gas. Salt domes at depths of less than 800 m, and over 300 m wide, are most suitable for constructing these caverns. Such salt domes are available in large numbers in Schleswig-Holstein and Lower Saxony.
