Clathrate Hydrogen Hydrate-A Promising Material for Hydrogen Storage

摘要

Hydrogen is viewed as a promising clean fuel of the future.A low-cost hydrogen storage technology that provides a high storage capacity and fast kinetics is a critical factor in the development of a hydrogen economy for transportation.The technologies to store hydrogen can be classified into three types:compression,liquefaction,and storage in a solid material.Compressing hydrogen requires a very high pressure to obtain enough hydrogen fuel for a reasonable driving cycle of 400-500 km,which in turn leads to safety issues related to tank rupture in case of accidents.The large amount of energy consumed during liquefaction and the continuous boil-off of hydrogen limit the possible use of liquid-hydrogen storage technology.Therefore,attention is currently focused on solid storage materials.
