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

Options

  1. ALi / P 4
  2. BSiH 4
  3. CNaNi 5
  4. 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.
