Can air energy pumps store energy

Contrasted with traditional batteries, compressed-air systems can store energy for longer periods of time and have less upkeep. Energy from a source such as sunlight is used to compress air, giving it potential energy. [1] The first utility-scale CAES project was in the Huntorf power plant in Elsfleth, Germany. Compressed Air Energy Storage (CAES) has emerged as one of the most promising large-scale energy storage technologies for balancing electricity supply and demand in modern power grids. Renewable energy sources such as wind and solar power, despite their many benefits, are inherently intermittent.
