It is known that molten crystals, in particular hydrates, have a tendency to supercooling, that is the chemical substance still remains in the liquid state even below the actual melting temperature or the transition temperature. It is further known to use the heat taken up by the crystals during melting for energy storage. (Use of the enthalpy of fusion or latent heat.) Heat stored in a latent manner can be kept for as long as desired without loss. The deliberate initiation of crystallisation and thus liberation of the heat is termed "retrieval". According to the invention, to the melt are added isotypic or epitaxial crystals, the melting point of which lies above the highest occurring temperature rise of the melt. The retrieval is carried out by cooling these crystals by external means until the desired crystallisation of the melt starts. From the crystal structure of the added foreign crystals, the formation of the "correct" crystals from the melt is then achieved.
