Abstract: The fatty acid stearic acid has been widely studied for its use in thermal energy storage applications as a phase change material (PCM). Stearic acid shows promise for this application because of its high volumetric storage density and its favorable thermal properties; however, two properties of stearic acid limit its use as a PCM: its low thermal conductivity and its propensity to leak liquid during the phase change process. This article studies the effects of the addition of olive pomace powder and expanded graphite to stearic acid in order to produce a form-stable composite PCM with an elevated thermal conductivity.
