    摘要: A plant for storing and discharging thermal energy comprises a first heat exchanger coupled to a heat source, a second heat exchanger coupled to a heat user, a fluid configured to store thermal energy, a storage device for the fluid, a circuit configured to couple the first heat exchanger, the second heat exchanger and the storage device. The storage device comprises N+B storage sections fluidly connected to each other, where N is equal to or greater than two and B is less than N; each of the N+B storage sections has a same containment volume. The fluid occupies a volume substantially equal to N times the containment volume. A separation gas is inserted in the storage device, is in contact with the fluid and is configured to always keep separate a hot portion of the fluid from a cold portion of the same fluid.
