Really  a storage media than a catalyst.

Assume SG of 1 in all cases.
Assume zero tank mass.

54 grams of H2/litre - about double what you get from 700 bar (!!!)
compressed Hydrogen storage.
Hydrogen has a calorific content of 34 kCal/gram or about 3 x that of petro=
l.
So equivalent to say 160 grams/litre of petrol.
ie 6 x less energy dense than petrol.
Present petrol tanks on mod size cars =3D say 50 l =3D 50 kg of fuel.
Equivalent 'carbazole' tank 300 litres / 300 kg OR smaller tank with
lesser range.
Equivalent mass to say 4 x passengers,
300 litre tank is about 670mm cube - approx 2'3" cube or 10.6 cubic feet.
All doable but a lot worse than petrol.
