Compressed Air Energy Storage Calculations

Compressed air energy storage or gravity water storage costs 10x less than any other based on 100 year vs 10 year lifetime of the system.

Calculations

• Work to compress, thus energy stored in isothermal conditions - is W = P1V1 * ln(P2/P1) [1]
• Let's take industrial gas cylinders with K, T, 3K, 6K standards - 300 cu ft for T [2]. 2200-2600 psi is the standard, but also 3000 PSI and 6000 PSI.

Other

• 150 PSI, 660 gal receiver tank - $3500 [3]
