storage of hydrogen is one of the key challenges in developing hydrogen economy. magnesium hydride (mgh2) is an attractive candidate for solid-state hydrogen storage for on-board applications. in this study, 10 wt.% zrb2 was co-milled with magnesium hydride at different milling times to produce nanocrystalline composite powder. the effect of milling time and additive on the hydrogen desorption ...

A continuum mechanics model is established for hydrogen storage in singleand multiwall carbon nanotubes (CNTs) and the bundle of single-wall CNTs. The model accounts for the deformation of CNTs, and van der Waals interactions among hydrogen molecules and between hydrogen and carbon atoms. The analytical expressions of hydrogen storage (number of hydrogen molecules per unit volume) in CNTs are o...

We propose new isoreticular metal-organic framework (IRMOF) materials to increase the hydrogen storage capacity at room temperature. Based on the potential-energy surface of hydrogen molecules on IRMOF linkers and the interaction energy between hydrogen molecules, we estimate the saturation value of hydrogen sorption capacity at room temperature. We discuss design criteria and propose new IRMOF...

In addressing the global demand for clean and renewable energy, hydrogen stands out as the most suitable candidate for many fuel applications that require practical and efficient storage of hydrogen. Supplementary to the traditional hydrogen storage methods and materials, the high-pressure technique has emerged as a novel and unique approach to developing new potential hydrogen storage material...

Hydrogen is considered to be the most promising new energy carrier to replace fossil fuels. The use of hydrogen in practical applications such as fuel cell driven vehicles and portable-devices, however, requires the development of safe and efficient hydrogen storage technologies/materials. High-pressure (>35 MPa) and cryogenic (< 20 K) hydrogen storage technologies may not be so practical for t...

The basic understanding of hydrogen molecular interaction with the solid surface is one of the important criterions to design the hydrogen storage materials. Such understanding at the molecular scale can only be achieved by employing appropriate electronic structure methods. Accordingly, the present article reports the theoretical work carried out in our laboratory for designing the hydrogen st...
