The energy losses for a LAES storage tank can be estimated to be around 0.1–0.2% of the tank energy capacity per day, which makes the LAES suitable as a long-term energy storage system. The effect of the storage pressure was investigated for a microgrid scale by Borri et al. [ 36 ].

Pressure differential is an intentional, controlled lowering of system pressure at the storage tank, which helps to maintain a constant pressure set point and lets you run your compressors more efficiently. "Lower the amount of pressure you are feeding into the system, and you increase system efficiency," Fresch said.

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.

Air receiver tanks hold air under immense pressure. This creates safety hazards if the tank is not up to code or is not maintained properly. Pressure vessels must be built to withstand high internal pressures over a long period of time. Over time, corrosion, stress and fatigue can make tank failure more likely.
