Abstract: A new composite phase change material for cold thermal energy storage applications is described in this paper. The authors combined dodecane into hydrophobic fumed silica to create a form stable PCM. Physical characteristics were studied using scanning through electron micrographs and Fourier transformation infrared. The Hot Disk TPS 2500 was used to measure the thermal conductivity of the composite, which was a desired low value needed for this type of application. An experimental setup to mimic a cold energy storage system was used and the PCM performed well under laboratory conditions. The authors conclude that this PCM has excellent potential for use in cold energy storage.
