Potential Sensible Filler Materials Thermal Energy Storage for Medium Range Temperature

摘要

The use of filler material (e.g. natural rock, ceramics, sand etc.) in sensible heat storage system is an effective way to store thermal energy, and had the advantage to have low cost compared to the configuration of two tank molten salt. However the choice of suitable filler material is a challenge that is based on several criteria. This present work intent to identify and select cost-effective sensible thermal energy storage (TES) system suitable for medium range temperature (100 ℃-300 ℃). Based on literature review, the main steps to select potential candidate solid TES as filler material, in direct or indirect with the HTF is developed. The thermal oil is the most adaptable heat transfer fluid in our case. Finally the potential candidate TES material are identified, and would be subjected to laboratory characterizations. In order to select the most successful candidates to be used in prototype scale TES system, installed later in the Green Energy Park (Ben Guerir Morocco).
