Compressed Air Energy Storage Diagram

Compressed air is a very expensive resource and one of the best ways to save energy is to operate the air compressor at the lowest possible discharge pressure.

The hydrostor angas a caes project uses electricity to run a compressor producing heated compressed air. High temperature hybrid compressed air energy storage system that can efficiently store grid level energy and release that energy when it is required to meet peak demand. Figure 1 conversion of atmospheric air into compressed air diagram showing 7 cubic units of air being compressed by an air compressor which requires energy and producing 1 cubic unit of compressed air at aproximately 7 times atmospheric pressure plus heat of compression and moisture. The compressor and turbine sections of the gas turbine.

Use the software tools training and publications listed below to improve performance and save energy. It incorporates a modified state of the art gas turbine and an underground reservoir that may be an aquifer a salt cavity or a mined hardrock cavern. Compressed air energy storage is the second biggest form of energy storage currently behind pumped storage. A facility can save 1 in compressed air energy costs for every 2 psi reduction in the compressor discharge pressure 4.

Compressed air energy storage caes is a way to store energy generated at one time for use at another time using compressed air at utility scale energy generated during periods of low energy demand off peak can be released to meet higher demand periods the first utility scale caes project was built in huntorf and is still operational while the huntorf caes plant was initially developed as. Compressed air is stored in an underground cavern which is kept at constant pressure. Compressed air energy storage caes is a technique for supplying electric power to meet peak load requirements of electric utility systems. The simplest type of a compressed air energy storage caes facility would be an adiabatic pro cess consisting only of a compressor a storage and a turbine compressing air into a container when storing and expanding when producing.

Heat is extracted from the air and kept inside a thermal store preserving the energy for later use. Applying best energy management practices and purchasing energy efficient equipment can lead to significant savings in compressed air systems. Compressed air energy storage involves converting electrical energy into high pressure compressed air that can be released at a later time to drive a turbine generator to produce electricity. In the first project of its kind the bonneville power administration teamed with the pacific northwest national laboratory and a full complement of industrial and utility partners to evaluate the technical and economic feasibility of developing compressed air energy storage caes in the unique geologic setting of inland washington and oregon.
