This is not heat being stored in a molten sodium pool. It is strontium carbonate being dissociated by heat into strontium oxide and carbon dioxide. The two components are kept separated until they are recombined to produce heat. That heat is used to drive hot air turbines and steam turbines.
It is much like dissociating water into hydrogen and oxygen and storing them until they can be recombined and the energy derived. However, the strontium carbonate heat dissociation shows much higher efficiency within the cycle than does electrolysis of water.
