An Experimental Investigation on the Combined Use of Phase Change Material and Rock Particles for High Temperature (~350 oC) Heat Storage
Abstract
The intermittent nature of solar energy requires integration of an energy storage system with collector devices in order to have an un-interrupted supply of energy in the absence of the availability of solar energy. The use of Phase Change Materials (PCM) and rock particles for heat storage has been a main topic in research for the past decades. However, little is known on the use of the combination of PCM and rock particles for high temperature heat storage with air as the medium of heat transfer.
