B$/$ Compressed Air Energy Storage $($CAES$)$

Mere is a schematic representation of an adiabatic CAES system:

Discuss the advantages and disadvantages of using an adiabatic CAES system versus a conventional system.

Determine the pressure of the air stored in the tank, taking into account the following data:

a$.$ compression work ~~$0\mathrm{.}217kW\frac{h}{k}g$

b$.$ temperature and pressure at the compressor inlet $=25C,1$ bar

c$.$ compressor efficiency $=90\%$

How much dry air can you store if the reservoir is a $150,000m^3$ salt cavern?
