How is energy stored in compressed air?

In Germany, a patent for the storage of electrical energy via compressed air was issued in 1956 whereby “energy is used for the isothermal compression of air; the compressed air is stored and transmitted long distances to generate mechanical energy at remote locations by converting heat energy into mechanical energy” .

Can compressed air be stored in rock caverns?

A pilot plant for the adiabatic storage of compressed air is currently being constructed in Switzerland (Section 4.7). Compressed air storage in rock caverns—particularly in lined rock caverns—could be interesting in future for countries which are not able to construct salt caverns but have adequate hard-rock potential.

Can a positive experience from underground storage of natural gas be extrapolated to compressed air?

The positive experience gained from underground storage of natural gas cannot be directly extrapolated to compressed air storages because of the risk of reactions between the oxygen in the air and the minerals and microorganisms in the reservoir rock.
