But look at energy per volume [1]: Diesel: 35.8 MJ/L Hydrogen: 9.17 MJ/L at 700 bar (10,000 psi). It will require a tank of 4x the volume for the same energy

But look at energy per volume [1]:
Diesel: 35.8 MJ/L
Hydrogen: 9.17 MJ/L at 700 bar (10,000 psi).
It will require a tank of 4x the volume for the same energy which comes with many additional challenges. Plus, a tank that can withstand 700 bar will have to be extremely strong and heavy which hurts your energy/mass ratio.
