Suruõhuenergiasalvestus

Suruõhuenergiasalvestus, often abbreviated as CAES, is a method of storing energy using compressed air. The fundamental principle involves compressing air and storing it in a reservoir, typically an underground cavern or an above-ground tank. When energy is needed, the stored compressed air is released, expanded, and used to drive a turbine connected to a generator, thus producing electricity. This process allows for the conversion of electrical energy into potential energy stored in the compressed air, and then back into electrical energy when required.

CAES systems are often integrated with power grids to manage fluctuations in electricity supply and demand. During periods of low electricity prices or high renewable energy generation, excess energy is used to compress air. Conversely, when electricity demand is high or renewable output is low, the stored compressed air is released to generate power. The efficiency of CAES systems can vary depending on factors such as the design of the system, the type of reservoir used, and the presence of heat recovery mechanisms. Advanced CAES designs, such as adiabatic CAES, aim to improve efficiency by capturing and reusing the heat generated during compression.
