Investigation of 20K H2 physisorption on MOFs: enhanced dormancy and an alternative to alleviate liquid-hydrogen-tank boil-off losses
This proposal aims to investigate the quantum states of adsorbed H2 on two different MOFs at boiling temperatures. The understanding of this process can lead to the design of new nanoporous materials that would significantly reduce the boil-off losses caused by large temperature differences of interior & exterior LH2 and achieve a highly efficient LH2 tank. In order to overcome boil-off losses, a new approach is proposed that combines two storage technologies (hybrid; liquefaction at 20 K and cryo-adsorption) taking advantage of both systems. In this experiments, the adsorbed quantum translational states on various MOFs as a function of loading and temperature will provide key information on whether the hybrid system (cryo-adsorption at 20 K) can enhance the boiling temperature of H2 above the critical temperature (20 K ¿ >40 K) to improve the boil-off loss for an off-board H2 storage tank. In addition, it will show the possibility of MOFs capacity can exceed the liquid hydrogen capacity. Our proposed work will lead to a fundamental understanding of the microscopic origin of the higher adsorbed capacity than LH2, and the utilization of an efficient LH2 storage tank.
