Abstract: Metal hydrides (MHs) have been considered as thermal energy storage (TES) materials for concentrated solar thermal applications. In this study, a TES system based on MgH2 was designed, constructed and optimized. The thermal conductivity of the MgH2/TiB2/ENG powder was measured using the transient plane source technique. It was found that the thermal conductivity of a MgH2/TiB2/ENG pellet pressed at 223 MPa for 5 minutes and measured in the axial mode under 1 bar Ar was 1.77(5) W/m∙K. Yhis value agreed with the value obtained by other researchers.
