Is compressed air energy storage economically viable in the home?

If you are using the biggest compressor at the local home store, you''re looking at at most 2 hp. NEMA suggests you''ll be looking at 78% efficiency on that motor. So just running the motor to generate the compressed air and running it in reverse to get the electricity back out, you''ve already lost 1 − .782 = 0.39 1 − .78 2 = 0.39 of your energy.

Compressed Air Energy Storage (CAES)

The special thing about compressed air storage is that the air heats up strongly when being compressed from atmospheric pressure to a storage pressure of approx. 1,015 psia (70 bar). Standard multistage air compressors use inter- and after-coolers to reduce discharge temperatures to 300/350°F (149/177°C) and cavern injection air temperature …
