A thermal energy storage module comprising one or more phase change alloys having a variable phase transition temperature between about 400° C. and about 1200° C. and having a latent heat of more than about 200 kJ/kg.
A thermal energy storage module comprising one or more phase change alloys having a general formula of Al—Si—Fe, wherein the concentration of Al is between about 40 atom percent and about 50 atom percent, the concentration of Si is between about 35 atom percent and about 45 atom percent, and the concentration of Fe is between about 10 atom percent and about 20 atom percent.
A method of storing heat comprising:
- providing one or more phase change alloys having a variable phase transition temperature between about 400° C. and about 1200° C. and having a latent heat of more than about 200 kJ/kg;
- charging the one or more phase change alloys by allowing heat transfer into the phase change alloy;
- and
- storing heat in the one or more phase change alloys.
