Enhancing Hydrogen Storage Properties of Metal Hybrides Enhancement by Mechanical Deformations

Increasing demand for energy and reducing fossil fuels have created the need for clean and reliable energy. Hydrogen-based energy systems are one of the new solutions in the long run. The main challenge of this technology is the production of a large amount of hydrogen from renewable sources. Some of the intermediates and their alloys produce metal hydrides in reaction with hydrogen gas or atom from an electrolyte. The reactive hydride reaction of these metals and their alloys introduces them as a reservoir for hydrogen storage. The nanoscale causes an increase in the rate of hydrogen uptake and hydrogen removal in metals and alloys. The use of milling mills has a wide application in the separation of hydride grains. The Mg and Mg2Ni nanocrystals obtained from milling mills have shown a faster rate of hydrogen uptake than the mass of these particles at a relatively low temperature. Because the surface effects increase and the length of the penetration path is reduced.
