Abstract (en)
[origin: WO2013152934A1] The invention relates to a heat store (1) for storing at least 100 MWh of thermal energy of a relatively warmer gas (2) in a charging state and for giving off thermal energy to a relatively colder gas (2) in a discharging state. In the charging state, said heat store has at least one inflow surface (10), provided with inflow openings (11), for introducing the gas (2), and at least one outflow surface (20), provided with outflow openings (21), for discharging the gas (2) after giving off heat to a granular heat storage medium (40), wherein the inflow surface (10) is formed at least in certain portions into a channel (12) which is surrounded, in particular completely, by the outflow surface (20), and wherein an intermediate space (30) in which the granular heat storage medium (40) is arranged is defined between the inflow surface (10) and the outflow surface (20).
