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 ...
In this article, the thermal properties and characteristics of a metal hydride alloy in a high hydrogen pressure environment were determined. An instrument was used to determine the thermal conductivity, thermal diffusivity, and specific heat of oxidized and activated Ti1.1CrMn powder under high hydrogen pressures. In doing so, the thermal conductivity of the oxidized powder increased from 0.80 W/m∙K to 1.6 W/m∙K, with increasing hydrogen pressure (from ...
This article described an experimental set up using the TPS instrument and a high pressure vessel to enable researchers to accurately measures the thermal conductivity of metal hydrides as a function of pressure. Metal hydrides have promise in applications of hydrogen storage in the auto industry, however a better understanding of their thermal properties is required. The authors investigated thermal conductivity, diffusivity, specific heat and thermal contact resistance. Experimental trials ...
The thermal transport properties of Ti1.1CrMn powder were determined. This metal hydride shows promise for use in hydrogen storage applications due to its excellent cold-start properties. The thermal conductivity, thermal diffusivity, and specific heat of oxidized and activated powder samples of this metal hydride were determined using the transient plane source technique in a high pressure vessel. It was found that the effective thermal conductivity of the samples showed ...
The purpose of this study was to analyze the thermal properties of metal hydride for its application in hydrogen storage systems. The thermal properties of metal hydride were measured using the Thermal Property Analyzer based on the transient plane source (TPS) method. To verify the accuracy of the TPS method, the thermal properties of stainless steel pellets were measured prior to the metal hydride samples. Unfortunately, the thermal behavior of ...
