Vanadium-based alloys are promising for the reversible, compressed storage of renewable hydrogen. To improve the hydrogen desorption plateau pressure of vanadium hydrides, V-3A binary alloys (i.e. V 97 Al 3 , V 97 Mn 3 , and V 97 Ru 3) were prepared by vacuum arc melting. Hydrogen absorption and desorption properties of the newly prepared V-3A samples were studied, and compared to vanadium hydrides, by pressure-composition-temperature measurements and first-principles calculations. Among V-3A binary alloys, V 97 Ru 3 achieved the highest hydrogen desorption plateau pressure while accommodating the highest atomic percentage of hydrogen. Meanwhile, it was also the alloy with the highest measured hardness. 2 Hydrogen desorption plateau pressures of V-3A alloys were complemented with DFT calculated formation energies. Calculated DOS, ELF and Bader charges showed that the influence of alloying on the electronic properties of the hydrides was comparable for Mn and Ru; whereas for Al alloying, vanadium dihydride bonding interactions were modified the most.
