Magnesium hydride is one of the most promising materials for safe storage and transport of hydrogen. It is mostly produced by long term mechanical milling and is thus very expensive what greatly limits its practical application. This applied research project is therefore aimed to verify economically attractive method of magnesium hydride production via direct spraying of molten magnesium or its complex alloy with compressed hydrogen and produce thus proper structure for repeatable storage of hydrogen.
The subject of the research is to study the effect of the composition of the melt, cooling rate, gas pressure and size of the powder particles onto the amount of hydrogen absorbed in the solid powder. In addition, the ability of such powder to absorb and desorb the hydrogen repeatedly without excessive creation of passive layer on the powder particle surfaces will be determined. The ways of further use of powder after exhausting its ability to effectively bind hydrogen will be examined as well. The successful results of the project could revolutionary help in the storage of energy from clean and renewable sources, thus contributing to the formation of sustainably clean environment.
