Enhancement and modeling of cryogenic solid-state hydrogen storage systems with a novel microchannel thermal management device

Graduation date: 2013Access restricted to the OSU Community, at author's request, from June 24, 2013 - June 24, 2014Compact storage systems demonstrating increased hydrogen storage capacity are the key to advancing the growth of the hydrogen economy throughout the world and reducing the global dependence on fossil fuels for transportation. The use of highly porous adsorbent materials for reversible hydrogen storage is a promising pathway towards achieving storage densities capable of reaching driving ranges comparable to gasoline automobiles without high-pressure compressed gas storage systems (>200 bars H₂). The focus of this effort is the enhancement of solid-state hydrogen adsorption systems through the development and inclusion of a microchannel thermal management device for efficient heat removal and uniform gas distribution in compressed beds of activated carbon and metal organic framework. The stainless steel microchannel device utilizes 250 μm walls to remove heat from the contacting adsorbent bed with liquid nitrogen coolant flow through 250 μm channel. Cryogenic (
