Compressed Air Energy Storage

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.

Compressed air energy storage.

Compressed air energy storage caes plants are largely equivalent to pumped hydro power plants in terms of their applications. But instead of pumping water from a lower to an upper pond during periods of excess power in a caes plant ambient air or another gas is compressed and stored under pressure in an underground cavern or container. Compressed air energy storage caes is a technique for supplying electric power to meet peak load requirements of electric utility systems. The compressor and turbine sections of the gas turbine.

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. Pg e is engaged in a project to explore the use of caes to power generators during peak periods when the energy is needed most. Compressed air energy storage caes is a promising energy storage technology that can lower costs for customers and reduce greenhouse gas emissions through a greater integration of renewable energy sources.
