Special Issue Information
Dear Colleagues,
Our fossil fuel consumption is harming Earth’s biodiversity and habitats, which is affecting quality of life and will eventually play a role in destroying humankind. The development of technologies to transform renewable energies into useful energy is essential. In current trends, hydrogen-based fuels are gaining much attention among the scientific community due to their unique properties, such as nontoxicity and carbon-free emissions. However, the storing and transportation of hydrogen is a problem. Metal hydride technology presents a simple and cheap way to store and release hydrogen compared with other technologies such as high-pressure storage tanks and liquid hydrogen (stored at −253 °C). Over the last decades, magnesium, as well as magnesium-based alloys, has played a vital role in hydrogen storage because of its superior properties, such as low density and being relatively inexpensive and highly abundant. In its pure form, magnesium can absorb hydrogen below 400°C up to 7.6 wt.%; nevertheless, it has low stability, especially readily reacting with oxygen, and low hydrogen absorption/desorption kinetics. The substitution of transition elements such as Al, Zr, Pd, and Cr into magnesium showed a significant improvement in cyclic life. Present trends have researchers showing much more interest in Mg-Ti intermetallic alloy for hydrogen storage because of its fluorite structure, which enables hydrogen ion diffusion kinetics. Carbon-based materials provide fast interfacial transport at different length scales of pores and shorten the diffusion path. This Special Issue will focus on hydrogen-storage-related areas, as mentioned below.
- Synthesis and characterization of transition-metals-substituted magnesium-based alloys for hydrogen storage application.
- Examination of hydrogen storage materials as anode materials for rechargeable batteries.
- Experimental and theoretical investigation of hydrogen absorption and desorption mechanisms into metal alloys.
- Advanced material design for hydrogen energy storage.
- Carbon and metal-carbon-based composites for hydrogen storage and conversion.
