The UV-activated thermal energy storage material shows the rapid crystallization and heat discharge upon visible light (blue LED) illumination. (Grossman Group at MIT)MIT researchers have combined conventional phase change material with an organic compound that responds to a pulse of light. "The new system," MIT News reports, "uses molecular switches that change shape in response to light; when integrated into the PCM, the phase-change temperature of the hybrid material can be adjusted with light, allowing the thermal energy of the phase change to be maintained even well below the melting point of the original material." The system could be used in a thermal battery to store heat from the sun or any other source and release the heat when needed.
