Compressed Air Energy Storage (CAES) refers to the compression of air during periods of low energy demand, for use in meeting periods of higher demand. Typically, compression is done with an electrically powered turbo-compressor; and expansion is done with a natural-gas powered 'expander' (heater) which drives a combustion turbine. Installations exist in Huntorf, Germany, and McIntosh, Alabama (USA). An additional facility is under development in Norton, Ohio. Air is stored underground in a cavern created by solution mining (salt is dissolved away) or an abandoned mine. Plants are designed to operate on a daily cycle, charging at night and discharging during the day. McIntosh is a town located in Washington County, Alabama, along U.S. Highway 43. ... Norton is a city located in Summit and Wayne counties in Ohio. ...
Grid energystorage is the use of various energystorage techniques to complement electric power generation plants on the transmission grid.
In many places, pumped storage is used to even out the daily generating load, by pumping water to a high storage reservoir during off-peak hours and weekends, using the excess base-load capacity from coal or nuclear sources.
Another grid energystorage method is to use off-peak electricity to compressair, which is usually stored in an old mine or some other kind of geological feature.
