Compressed air energy storage

Compressed Air Energy Storage (CAES) is a method of storing energy by using electricity to compress air into underground caverns or containers. When electricity is needed, the stored compressed air is released, heated, and expanded to drive turbines that generate electricity. This system acts like a rechargeable energy reservoir, balancing supply and demand, and enabling renewable energy sources like wind and solar to be stored and used when production is low. CAES provides a reliable, large-scale way to store clean energy, helping stabilize power grids and reduce reliance on fossil fuels.
