What are Mg-based hydrogen storage materials?

Use the link below to share a full-text version of this article with your friends and colleagues. Mg-based hydrogen storage materials have drawn considerable attention as the solution for hydrogen storage and transportation due to their high hydrogen storage density, low cost, and high safety characteristics.

Are metal hydrides suitable for hydrogen energy storage?

Metal hydrides (MH) are known as one of the most suitable material groups for hydrogen energy storage because of their large hydrogen storage capacity, low operating pressure, and high safety. However, their slow hydrogen absorption kinetics significantly decreases storage performance.

Can nanostructured mg-based hydrogen storage materials be used for thermal storage systems?

If the synthesis process for the low-cost and large-scale nanosized Mg-based hydrogen storage materials can be developed, significant cost savings for thermal storage systems will be achieved through the use of nanostructured Mg-based hydrogen storage materials.

Are magnesium-based hydrogen storage alloys a good choice for metal hydrides?

Among the various metal hydrides, magnesium-based hydrogen storage alloys have attracted significant attention due to their high hydrogen storage capacity (up to 7.6 wt.% for MgH 2), abundant reserves, low cost, and good reversibility [11, 12].

What is the hydrogen storage capacity of MG-Ti alloy?

The Mg-10wt.%Ti alloy has been reported to have a hydrogen storage capacity of 6.0 wt.% and rapid absorption/desorption kinetics at temperatures around 300–350 °C . The addition of transition metal catalysts and the nanostructuring of Mg-Ti alloys have been shown to further improve their hydrogen storage performance .

Are mg-Co alloys a hydrogen storage material?

The Mg-Co alloys, particularly the Mg 2 Co intermetallic compound, have been studied as potential hydrogen storage materials due to their high hydrogen storage capacity and good reversibility . The Mg 2 Co alloy has a theoretical hydrogen storage capacity of 4.5 wt.% and a desorption temperature of around 300–350 °C .
