The invention relates to a system (10) having 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, having a storage component comprising an air store (18) for storing the liquefied air, and having 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). According to the invention, an apparatus (14) for permanent water electrolysis having at least one first heat exchanger (94, 96) is provided, by means of which the heat energy generated during the electrolysis is absorbed by a fluid flowing through the first heat exchanger (94, 96). The first heat exchanger (94, 96) is connected to the first heat line (68) such that the heat energy generated during the electrolysis is dissipated via the first heat exchanger (94, 96) by means of the fluid and is fed to the evaporation apparatus (62).
