What Is Air Compressor?

What is an Air Compressor? An air compressor is a pneumatic device that converts power (using an electric motor, diesel, or gasoline engine, etc.) into potential energy stored in pressurized air (i.e., compressed air). By one of several methods, an air compressor forces more and more air into a storage tank, increasing the pressure.

Overview of Energy Storage Technologies

Potential Energy Storage. Compressed air energy storage uses wind turbines to drive compressed air into underground aquifers. The air is released to generate electricity when needed. This is a new twist on the idea of using wind energy in a way that removes the variability to a large extent and increases the dispatchability.
