Experimental assessment of physical upper limit for hydrogen storage capacity at 20 K in densified MIL-101 monoliths†
Abstract
The physical upper limit of hydrogen uptake for powder and compressed pellet MIL-101 has been experimentally investigated. Maximum uptake in pellets at 20 K achieves 9.6 wt% and 42 g Lā1. Moreover, cryo-adsorption of hydrogen on pellets compared to liquid H2 possesses a larger temperature window for operation without boil-off loss, which will be beneficial for industrial applications.
