||Efficient, economical, & safe storage & delivery is essential for using hydrogen as a fuel in mobile and portable applications. The thermal design of solid state hydrogen storage devices involves coupled heat and mass transfer with heat generation and chemical reactions. Important design considerations include gravimetric hydrogen storage capacity and charging/discharging kinetics. A variety of storage materials such as intermetallics, complex hydrides, carbons, metal organic frameworks, etc. have been suggested, but there was a severe lack of data on their thermodynamic and thermophysical material properties. Analytical and experimental work on the thermal engineering aspects of solid state hydrogen storage has been conducted by the speaker’s research group over the past 20 years. Recently, in order to achieve higher gravimetric storage densities, complex hydrides have been investigated. In this talk, the speaker shares his results from this work. Based on his broad experience on solid sorption, other applications, such as carbon sequestration, power generation, and thermal energy storage will also be explored.
