Technical. Compressed Air Index - [15] Energy stored in a cubic meter of volume at 70 bar is 6.3 kWhr. [16]. Compare to 300 cu ft - which correcponds to 42l volume inside - 0.04 cu meter - but equiv to 0.1 of the above if done at 200 bar - then energy stored in the gas cylinder is 0.6 kWhr. And before, we said we have 12 minutes of 0.75 kW.

Most energy recovery ventilation systems can recover about 70-80% of the energy in the exhaust airstream and deliver that energy to the incoming air for conditioning purposes. [31] Figure 7: Energy Recovery Ventilation Whole-House System (Market Reports World)
Compressed air energy storage (CAES) is a method of compressing air when energy supply is plentiful and cheap (e.g. off-peak or high renewable) and storing it for later use. The main application for CAES is grid-scale energy storage, although storage at this scale can be less efficient compared to battery storage, due to heat losses.
So, let''s do the math. The one-horsepower air motor outputs about 0.75 kW of shaft power. To produce this power: A lossless compressor must consume about 7.5 kW (30 x 25/100 = 7.5 kW) Leaks …

When the compressed air temperature in the cylinder is used for calculation, it can be considered as: (19) T a = C r T a 1 + ( 1 − C r) T a 2. The water mist absorbs the heat of the air and uses it to heat up and evaporate. The total heat balance equation of the water mist is: (20) d Q x = L d M u w + d Q s.
