Special Issue Information

Dear Colleagues,

Fossil fuels (petroleum, natural gas, and coal) provide most of the energy consumed worldwide, leading to a number of economic, political, and environmental issues. Transition towards renewable sources of energy and new energy vectors is imperative in our society. In this sense, hydrogen has been proposed as a promising energy carrier, and a number of technologies have been developed to produce this gas from renewable sources. These technologies include catalytic reforming of biomass-derived molecules (in replacement of classical catalytic reforming of natural gas), water electrolysis, thermochemical and photocatalytic water splitting, and biomass gasification, as the most representative efforts.

Hydrogen storage has also been pointed out as being critical for bringing these technologies to the commercial scale. New solid materials with appropriate porosity and textural and hydrogen-containing liquids have been identified as promising technologies for storing large amounts of hydrogen.   

The present Special Issue welcomes contributions (research papers, reviews and perspective) on technologies for renewable hydrogen production and storage. Papers dealing with market analysis and technoeconomic analysis of some of these technologies are also encouraged.

A new method of hydrogen generation from water, by irradiation with CW infrared laser diode of graphene scaffold immersed in solution, is reported. Hydrogen production was extremely efficient upon admixing NaCl into water. The efficiency of hydrogen production increased exponentially with laser power. It was shown that hydrogen production was highly efficient when the intense white light emission induced by laser irradiation of graphene foam was occurring. The mechanism of laser-induced dissociation of water is discussed. It was found that hydrogen production was extremely high, at about 80%, and assisted by a small emission of O2, CO and CO2 gases.

Hydrogen has been receiving great attention as an energy carrier for potential green energy applications. Hydrogen storage is one of the most crucial factors controlling the hydrogen economy and its future applications. Amongst the several options of hydrogen storage, light metal hydrides, particularly nanocrystalline magnesium hydride (MgH2), possess attractive properties, making them desired hydrogen storage materials. The present study aimed to improve the hydrogen storage properties of MgH2 upon doping with different concentrations of zirconium carbide (ZrC) nanopowders. Both MgH2 and ZrC were prepared using reactive ball milling and high-energy ball milling techniques, respectively. The as-prepared MgH2 powder was doped with ZrC (2, 5, and 7 wt%) and then high-energy-ball-milled for 25 h. During the ball milling process, ZrC powders acted as micro-milling media to reduce the MgH2 particle size to a minimal value that could not be obtained without ZrC. The as-milled nanocomposite MgH2/ZrC powders consisted of fine particles (~0.25 μm) with a nanosized grain structure of less than 7 nm. Besides, the ZrC agent led to the lowering of the decomposition temperature of MgH2 to 287 °C and the reduction in its apparent activation energy of desorption to 69 kJ/mol. Moreover, the hydrogenation/dehydrogenation kinetics of the nanocomposite MgH2/ZrC system revealed a significant improvement, as indicated by the low temperature and short time required to achieve successful uptake and release processes. This system possessed a high capability to tackle a long continuous cycle lifetime (1400 h) at low temperatures (225 °C) without showing serious degradation in its storage capacity. Full article
