The ternary LiNH2-MgH2-LiBH4 hydrogen storage system has been extensively studied by adopting various processing reaction pathways. The stoichiometric ratio of LiNH2:MgH2:LiBH4 is kept constant with a 2:1:1 molar ratio. All samples are prepared using solid-state mechano-chemical synthesis with a constant rotational speed, but with varying milling duration. All samples are intimate mixtures of Li-B-N-H and MgH2, with varying particle sizes. It is found that the samples with MgH2 particle sizes of approximately 10nm exhibit lower initial hydrogen release at a temperature of 150°C. The as-synthesized hydrides exhibit two main hydrogen release temperatures, one around 160°C and the other around 300°C. The main hydrogen release temperature is reduced from 310°C to 270°C, while hydrogen is first reversibly released at temperatures as low as 150°C with a total hydrogen capacity of 6 wt.%.

Desorption Mechanism

Hydrogen storage capacity of a carbon nanotube (CNT) sample is investigated using Elastic Recoil Detection Analysis (ERDA) at constant hydrogen uptake pressure of 5 bar and different adsorption temperatures within 30°C–500°C. The results of hydrogen concentration versus temperature revealed three distinct temperature intervals in which a certain adsorption or desorption mechanism is dominant. Moreover, the results showed that hydrogen storage capacity of CNTs at the applied conditions of pressure and temperature is about 0.1 wt.% which is well below the DOE requirements for a viable hydrogen storage system. The physidesorption activation energy is calculated using the Arrhenius plot to be 6 kJmol-1.
