Which of the given compounds can enhance the efficiency of hydrogen storage tank?

Options

A $Li / {P}_{4}$
B ${SiH}_{4}$
C ${NaNi}_{5}$
DDi-isobutylaluminium hydride

Correct answer

C. ${NaNi}_{5}$

Step-by-step solution

Dihydrogen gas is converted into liquid state by cooling to 20K. This would require expensive insulated tanks. Tanks are metal alloy like

{NaNi}_{5}, Ti - {TiH}_{2}, Mg - {MgH}_{2,}

etc. are in use for storage of dihydrogen.
