Compressed air energy storage (CAES), a promising energy storage technology exhibiting advantages of large capacity, low capital cost and long lifetime, can solve this problem efficiently. It functions by consuming excess or available electrical power to compress air and store it in a large above- or below-ground void.
As promising as compressed air appears as a storage medium, it does have some drawbacks. When air is compressed, it heats up. When it expands, it cools. Cold air isn''t as effective at producing power when it is run through a turbine, so before the air can be used, it needs to be heated, frequently using natural gas, which produces CO …

The basic idea of CAES is to capture and store compressed air in suitable geologic structures underground when off-peak power is available or additional load is needed on the grid for balancing. The stored high-pressure air is returned to the surface and used to produce power when additional generation is needed, such as during peak demand ...
Access huge amounts of energy when you need it. Compressed air energy storage (CAES) is a proven large-scale solution for storing vast amounts of electricity in power grids. As fluctuating renewables become increasingly prevalent, power systems will face the situation where more electricity is produced than it is needed to cover the demand.
