Abstract: The present invention relates to a device for storing electricity and high-temperature energy. The purpose of the present invention is to provide a device for storing electricity and high-temperature energy, which can efficiently store both high-temperature energy and electric energy of various qualities, and which can be operated and managed conveniently such that same can be utilized in a range substantially wider than that of conventional devices. More specifically, the purpose of the present invention is to provide a device for storing electricity and high-temperature energy, which operates in such a manner that an operating fluid that is easy to handle, such as water or air, is used to directly store thermal energy in a thermal storage medium with a high-temperature operating fluid, or electric energy is converted into thermal energy, which is stored in a thermal storage medium, and the thermal energy is recovered, if necessary, with a low-temperature operating fluid.
