The plant for the periodic charging and discharging of a gas reservoir comprises a gas circuit containing a compressor and a heat exchanger. A line for supplying the gas for storage and for discharging stored gas to a consumer is connected to the gas circuit. The gas is stored as a gas at low temperature and elevated pressure or as a liquid gas at substantially ambient pressure. A heat exchanger disposed in the gas circuit is operated as a cooler or heater depending on whether gas is to be stored or discharged. The heat-transfer or refrigerant liquid flowing through the heat exchanger is either cooled in a refrigerating machine or heated in a heater. Depending upon requirements, a gas, e.g. natural gas, can be prepared in one and the same plant for charging a reservoir or for emptying the same.
