Grid energy storage
OverviewFormsBenefitsEconomicsSee alsoFurther readingExternal links
One grid energy storage method is to use off-peak or renewably generated electricity to compress air, which is usually stored in an old mine or some other kind of geological feature. When electricity demand is high, the compressed air is heated with a small amount of natural gas and then goes through turboexpanders to generate electricity.
Making the numbers work for a residential energy storage system
