  "textContent": "The station has compression devices (2-5) and heat exchanger devices (6-9) connected in series in an injection-pressure stage. The heat exchanger devices and expansion devices (13-16) connected in series in a delivery-pressure stage. A number of injection-pressure stages is unequal to a number of delivery-pressure stages. Each heat exchanger device is divided into portions through which a compressible medium (20) i.e. ambient air, are flow independent each other, where temperature gradients within the adjacent portions run parallel to each other. The heat exchanger devices are formed as regenerative heat accumulators. The expansion devices are formed as gas turbines. An independent claim is also included for an energy storage method for temporary storage of energy in form of pressure energy in a compressible medium in a pressure reservoir and in form of heat energy.",
