1. A system (10), comprising:
a liquid air energy storage and power plant apparatus (12), having a charging component (16) comprising a compressor (26) for compressing supplied air and comprising a liquefier (40), which adjoins said compressor and which serves for liquefying the air, a storage component comprising an air storage (18) for storing the liquefied air, and a discharging component (20) comprising an evaporation apparatus (62) for converting liquid air into gaseous compressed air, wherein heat energy is supplied to the evaporation apparatus (62) via a first heat line (68), and comprising an expansion apparatus which serves for expanding the compressed air and which has a turbine (76) and a generator (78) which is connected to the turbine (76);
an apparatus (14) for permanent water electrolysis having at least one first heat exchanger (94, 96), by means of which the heat energy generated during the electrolysis is absorbed by a fluid flowing through the at least one first heat exchanger (94, 96), which first heat exchanger (94, 96) is connected to the first heat line (68) in such a way that the heat energy generated during the electrolysis is dissipated via the at least one first heat exchanger (94, 96) by means of the fluid and is fed to the evaporation apparatus (62); and
at least one third heat exchanger (64) is connected downstream of the evaporation apparatus (62), which at least one third heat exchanger (64) is used to supply further thermal energy to the compressed air from the evaporation apparatus (62) and to set the required temperature of the compressed air.
