Hydride-Induced Amplification of Performance and Binding Enthalpies in Chromium Hydrazide Gels for Kubas-Type Hydrogen Storage
Describes the effect of hydride ligands increasing the binding enthalpies and room temperature hydrogen storage performance of transition metal hydrazides, which now retain up to 95% (MOF materials only retain 15%) of activity at 298K as compared to 77K. Achieved a volumetric density of 42kg/m3 under the same conditions, surpassing the 2015 US Department of Energy System target of 40kg/m3 with no observable kinetic barrier or any of the thermodynamic issues that thwart physisorption materials and hydrides. These materials have the highest room temperature capacity of any storage material not requiring a temperature swing for adsorption.
