Compressed Air Energy Storage Catching On

Last year we brought you news about Pacific Gas & Electric using compressed air energy storage to solve energy needs.  Now it seems Southwest Solar Technologies is taking it a step further.  Instead of just using wind turbines, it will combine, wind, solar, and other renewable energy resources to make renewable energy grid ready.

If you are not familiar with the technology, it basically uses off peak and surplus energy to power giant compressors that will fill salt caverns with air.  When power is at a greater demand than what is being produced, or in the case of solar, the renewable energy is not available, it will use the air pressure in the caverns to power the generators to produce electricity.

Traditional power plants like a 110 MW plant in McIntosh, Alabama have used this technology successfully for 16 years.  It seems the transition to a renewable source would be the next logical evolution in renewable energy.
