The method involves unloading a gas from a high density storage unit (1) into a low density storage unit (2) through a working machine. The gas is loaded from the low density storage unit into the high density storage unit through a compressor. The heat ge...

The method involves providing turbo engines (02,03) for compressing and/or decompressing the compressed air. The turbo engine is made to communicate with a pressure accumulator (04) for temporarily storing the compressed air. A heat reservoir (05) is provi...

The method involves compressing and/or decompressing compressed air by a turbine engine. A pressure reservoir is in temporary communication with the turbine machine for intermediate storage of the compressed air. A heat storage chamber is sealed in a gas-t...

The device has two successively arranged storage portions that are provided with different storage materials. The storage materials only up to the maximum temperature to which they are resistant, are loaded with heat. The total amount of heat of the heat c...

The plant (1) has a heat reservoir (11) arranged in a secondary circuit (13), which is separated from a pipeline (4) of a pipeline system (3) by a heat exchanger (14). Compressed air flows on a primary side, and heat transfer liquid flows on a secondary si...

The method involves mixing a portion of compressed air extracted from compressed-air accumulator (04) with another portion of the compressed air extracted from the compressed air accumulator at constant turbo-machine (02,03) inlet temperature (T). The latt...
