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.
In general, the level of interven-tions depends on the share of renewable electricity and capacity in the power system. For a ten percent renewable electricity share, the increase of reserve capacity is estimated to range between 1.5% and 4% of the installed variable capacity. However, variability issues may also be solved through more inter ...
