“…Nano-structured cages with curvature such as single-walled carbon nanotubes, boron nitride nanotubes (BNNT), or B-C-N composite nanotubes and buckyball-like clusters of C or BN are among the most widely investigated nano-materials for hydrogen storage (Barman et al, 2008;Bhattacharya et al, 2008a, b;2009b;2010). The presence of a highly specific surface area is promising for physical and chemical optimization of such materials.…”

“…However, relatively poor kinetics and high temperature of dehydrogenation as well as release of volatile contaminants such as borazine are posing big challenges for practical application of AB (Staubitz et al, 2010;Chua et al, 2011). When one H atom in AB is replaced by an alkali or alkaline earth metal (M), a new class of materials called metalamidoboranes (MAB) is formed, which in turn can be used for efficient storage of molecular hydrogen Shevlin et al, 2011).…”

In the current renewable energy scenario, one of the thrust areas is hydrogen generation and storage in an environmentfriendly and cost-effective fashion. The primary challenge of efficient generation as well as storage of hydrogen has triggered R&D all over the world. Various routes such as solar photovoltaic, solar thermal, nuclear and bio-inspired routes are being vigorously pursued; the costs are still rather high for the hydrogen economy to be viable for renewable energy. There has been a concerted effort in many Asian countries, to push the frontiers of hydrogen energy for automobile and other applications. From the point of view of fundamental research, Hydrogen storage in solid state is a vibrant research area in materials science. Various types of materials, viz. metal hydrides, complex hydrides, chemical hydrides, and new materials such as functionalized nanostructures have been reported as candidate materials for hydrogen storage. However, their storage efficiencies, desorption kinetics and thermodynamics are yet to be optimized for practical applications. The article presents a broad overview of the current status of these materials issues for efficient storage of hydrogen in solid state. In particular, the focus here is on how first-principles computational approach can be gainfully utilized to design various low-Z complex hydrides (along with their decomposition pathways), as well as functionalized nanostructures (H 2 adsorption and desorption processes). Some of the outstanding issues and challenges will be discussed.

“…severe disadvantages in especially gravimetric efficiency, alternatives are sought after. (Eberle et al, 2009;Felderhoff et al, 2007;Hamilton et al, 2009;Marder, 2007;Staubitz et al, 2010) Since there are some materials that consist of an amount of hydrogen, that is high enough to compete with the aforementioned physical storage solutions, the storage of hydrogen in a chemical compound is discussed intensively lately. One important compound with one of the highest hydrogen contents possible is ammonia borane.…”

A GBH/LiBH4 coordination system with favorable dehydrogenation

A novel combined hydrogen storage system LiBH 4 /[C(NH 2 ) 3 ] + [BH 4 ] À (GBH) complexes were reported. By a short time ball milling of LiBH 4 and guanidinium chloride, a series of new LiBH 4 /GBH complexes were produced. It was found that the two potential hydrogen storage materials exhibited a mutual dehydrogenation improvement, releasing >10.0 wt.% of fairly pure H 2 from LiBH 4 /GBH below 250 C. Further investigations revealed that balancing the protic and hydridic hydrogens, and the complexation between LiBH 4 and GBH, are two important roles in the improvement of the dehydrogenation of this system, which may serve as an alternative strategy for developing a new metal borohydride/B-N-H system with favourable dehydrogenation.
