Is vanadium a suitable material for hydrogen storage and permeation?

Vanadium and vanadium based alloys are extensively studied as a candidate material for hydrogen storage and permeation applications. The efforts were made to enhance the cyclic hydrogen storage capacity and prevent the pulverization. A large number of elements could form the alloy with vanadium in a wide range of concentrations.

What is the reversible hydrogen storage capacity of a vanadium based alloy?

Vanadium (V)-based alloys attract wide attention, owing to the total hydrogen storage capacity of 3.8 wt% and reversible capacity above 2.0 wt% at ambient conditions, surpassing the AB 5 -, AB 2 - and AB-type hydrogen storage alloys.

Can a vanadium alloy reduce the cost of hydrogenation?

Vanadium alloys The addition of alloying elements has been found effective not only to reduce the cost but also to alter the hydrogenation properties such as dissociation pressure and hydrogen storage capacity.

What is vanadium-hydrogen system?

Vanadium-hydrogen system Hydrogenation of vanadium initiated with the formation of solid solution phase which is known as α phase. In α phase, the concentration of hydrogen is directly proportional to the square root of hydrogen pressure which is known as Sieverts law as shown by Eq.

Is vanadium a good hydride forming metal?

The metallic vanadium has an excellent hydrogen storage properties in comparison to other hydride forming metals such as titanium, uranium, and zirconium. The gravimetric storage capacity of vanadium is over 4 wt% which is even better than AB 2 and AB 5 alloys.

Is V a good candidate for on board hydrogen storage materials?

Additionally, V is regarded as a promising candidate for on board hydrogen storage materials due to its higher gravimetric hydrogen storage capacity (about 4 wt%) than AB 5, AB 2, and AB type hydrogen storage alloys [34, 35].
