Fossil fuels are increasing carbon footprint in the world; to mitigate this thermal energy storage materials are gaining importance. Thermal energy storage materials in organic “Plastic Crystals” such as C(CH2OH)4-PE, (CH3)C(CH2OH)3-PGand a few others, store a large amount of thermal energy during first order solid state phase transitions. A handful of these materials are commercially available that have fixed phase transition temperatures, so solid solutions are with different phase transition temperatures to make more materials available. We recently found that “Continuous Phase Transitions,” can store significant amount of heat but in a wide range of temperature, mimicking “stepped” first order phase transitions. The CALPHAD calculations allow development of a wide range of materials with optimum energy storage properties. Issues related to extrapolation of Gibbs energy functions from heat capacity data, isotherms of selected ternary systems, pseudo-binary isopleths from the ternaries will be present.
