The air receiver tank has three main functions in your compressed air system: It stores compressed air that can be used for short, high-demand events. It provides a steady air signal to compressor controls. When used as a "wet tank", it acts as a secondary heat exchanger, increasing the efficiency of your air dryer.

The tank, engine, and generator should be sized to charge up over 7 hours between 01:00 and 08:00 and release the energy during the other 17 hours of the day. I''m assuming that regardless of when during the day the energy is actually released it is either used by me or goes back into the grid and runs the meter backwards to offset my day-usage.

Compressed-air energy storage (CAES) is a way to store energy for later use using compressed air. At a utility scale, energy generated during periods of low demand can be released during peak load periods. The first utility-scale CAES project was in the Huntorf power plant in Elsfleth, Germany, and is still operational . The Huntorf plant was initially developed as a load balancer for fossil-fuel-generated electricity
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.
LNG storage. The advantage of LNG is that the significant reduction in volume when natural gas is liquefied makes it practical to store. LNG is stored in cryogenic tanks designed to keep the LNG below the vaporization temperature. The job of the tank is to contain the gas and to insulate it from warming due to heat from the surrounding air.
