Hydrogen storage: Materials, methods and perspectives

Nitrogen Doped Graphene as Potential Material for Hydrogen Storage

“…The second step is reversible hydrogen storage in suitable materials or adsorbed on appropriate surfaces which require several issues to be solved [5]. A particularly significant application is in hydrogen-fueled vehicles [6]. The storage capacity for possible commercial utilization of hydrogen as energy source is 6.5 wt% as postulated by US-DOE (Department of energy) [7].…”

Transition of Future Energy System Infrastructure; through Power-to-Gas Pathways

“…Consideration of safety and risk of storage systems are a perquisite for the location of any storage technology. Compressed storage tanks are the simplest storage systems, and despite the low storage density, higher pressure results in the higher density of storage and consequently higher costs [78,79].…”

Mg-based Nanocomposites for Hydrogen Storage Containing Ti-Cr-V Alloys as Additives

“…Hydrogen is considered the ideal energy carrier since it has a very high energy content and water is the only by-product after its use in a fuel cell or internal combustion engine 1 . However, the development of safe and effective forms of H 2 storage remains as a critical technological challenge.…”

“…Gaseous hydrogen can react with some metals and alloys to form metal or complex hydrides, which allow hydrogen storage at the solid state. This represents a more suitable form of storage than the use of H 2 gas at high pressures or alternatively liquid hydrogen at very low temperatures 1 . MgH 2 is a very interesting phase for hydrogen storage, mainly due to the low cost of Mg and its very high gravimetric capacity (7.6 wt.%), being the highest among the metal hydrides 2 .…”

“…Transition metals, their oxides or fluorides are known to exhibit important catalytic action during the reactions of hydrogen absorption/desorption by Mg/MgH 2 6-8 . However, clear descriptions of the mechanisms involved in the catalytic action of the additives are still unclear in most of the cases, remaining as an interesting topic of fundamental research 9 , even considering the high amount of studies published on this topic over the last years [1][2][3][4][5][6][7][8][9][10] . On the other hand, Ti-Cr-V alloys were one of the first systems studied for hydrogen storage applications 11,12 .…”
