Abstract

Apparatus 300 for storing energy including a first engine stage 330 acting as a compressor during a charging phase of a cycle and as an expander during a discharging phase; a first heat store 320 for receiving and storing thermal energy from gas compressed by the first engine stage during the charging phase; a second engine stage 340 acting as an expander during the charging phase to expand gas received from the first heat store 320 and as a compressor during the discharging phase; a second heat store 310 for transferring thermal energy to gas expanded by the expander during the charging phase; a heat rejection device 385, 380 for dissipating unwanted heat from a gas flow and control means 370 for varying the degree of thermal coupling between the gas flow and the heat rejection device, or, its level of heat rejection performance, between a lower level during a first part of the cycle and a higher level during a second part of the cycle.
