Claim:
1. A steam thermal storage system comprising: a latent heat thermal storage module and a liquid displacement thermal storage module, the latent heat thermal storage module comprising a reservoir, the liquid displacement thermal storage module comprising a reservoir different from the reservoir in the latent heat thermal storage module, the reservoir of the liquid displacement thermal storage module containing a volume of liquid in a lower part and steam in an upper part, the liquid volume including an upper zone and a lower zone placed below the upper zone; a first connector for transferring liquid between the upper zone in the liquid volume and the latent heat thermal storage module; a second connector for transferring liquid between the lower zone in the liquid volume and an external circuit; a third connector for transferring steam or a liquid-steam mix between the upper part of the reservoir in the liquid displacement thermal storage module and the latent heat thermal storage module; and a fourth connector for transferring steam between the system and the external circuit, wherein the fourth connector comprises a connection opening up in the upper part of the liquid displacement thermal storage module configured to transfer the steam between the system and the external circuit.
