High capacity hydrogen storage: Basic aspects, new developments and milestones

摘要: One of the major technical bottlenecks in hydrogen economy is storage. None absorption materials known today exclusively meets all required properties such as storage capacity (∼4.5 wt%), reaction enthalpy (15–24 kJ/mol), kinetics (0.02 g H2/s), cycle life (>10,000 cycles), desorption temperature (∼<100 °C), etc. However, there are striking recent developments; for example, development reactive hydride composites (RHC), nanoconfinement hydrides by nanoscaffold materials, synthesis new generation alkali–alkaline earth composite structures and air stable nanocomposite system, All these conceptually interesting candidates, but when it comes to practical reality, still significant problems need be circumvented. The present review therefore attempts throw some insight on almost classes materials. very basic aspects presented promise state art candidates indicated.
