Energy density of liquid hydrogen is poor. If you take a Tesla 3 battery of 75kwh you would need 35 litres of liquid H2 to have the equivalent energy or 8 litres of petrol. Even if you assume that both the leccy and H2 vehicles are 100 % efficient ( they wont be) and the petrol engine is 40% then the petrol quantity equivalent becomes 21 litres

The three equal-size carbon tanks mounted under the boot floor and the rear seat hold a total of 6.33 kilos of hydrogen. The NEXO thus has the largest tank [capacity] of all available fuel-cell passenger cars and, thanks to an optimised drivetrain/power train, the longest range as well: 756 km.
