Abstract

An apparatus 100' for storing energy using a gas-based thermodynamic cycle comprising a circuit including a hot half-engine stage 130' acting as a compressor during charging and an expander during discharging; a cold half-engine stage 140' which acts as an expander during charging and a compressor during discharging; a first heat store 120' for receiving and storing thermal energy from gas compressed by the hot half-engine stage in charging mode, and which transfers energy to the gas compressed by the cold half-engine in discharging mode; and a second heat store 110' for transferring thermal energy to gas expanded by the cold half-engine stage during charging, and receiving and storing thermal energy from gas expanded by the hot half-engine stage during discharging. A first valve 220 connects a higher pressure part of the circuit to a gas reservoir 205 at a pressure equal to or below the higher pressure when gas needs to be withdrawn from the circuit and a second valve 210 connecting a lower pressure part of the circuit to the gas reservoir 205 at a pressure greater than or equal to the lower pressure when gas needs to be added to the circuit.
