Principle of compressed air solar container in abandoned mines

The concept of AM-CAES involves storing excess energy generated from renewable sources like wind and solar power by compressing air and storing it in underground caverns. Researchers in China developed a new compressed air energy storage system that uses flooded roadways in abandoned coal mines to store compressed air and heat for nighttime power generation. Based on this, relevant research on AM-CAES was summarized in this paper, elucidating its fundamental principles and the then-current status of thermodynamic model derivation. The theoretical research progress of AM-CAES in four aspects: site selection suitability, operational efficiency, safety. Wang and his team highlight how this technology can transform abandoned mines into valuable assets for energy storage, offering. The compressor and turbine facilities are installed above the ground,while "dry mine" is ideal for this type of system.
