Hydrogen can't be stored in conventional fuel tanks because it is a gas at normal temperature and pressure.
None. You do not store fuel in a pump.
Petrol
the future of petrol is not in fact petrol it is hydrogen hydrogen in the future will be used as a fuel in our cars because of it's abundance and the fact that the only thing that comes out of the exhaust is water H20. honda have already made a hydrogen car (not on sale) and if you search it up you will probably find it. when we find an easier way of extracting it it will almost certainly replace the void t left by petrol
because water is not a fuel but it is a byproduct of burning of hydrogen. while petrol is itself is fuel.
It burns nicely, holds lots of energy, is easy to store and transfer.
because the car is heavy or because there is no petrol in water. They are working on an engine that runs on water. It separates the hydrogen from the oxygen and uses the hydrogen as fuel.

petrol is a hydrocarbon fuel
Petrol is more efficient as a fuel than ethanol, because the energy generated by burning a fuel is primarily released by formation of bonds between oxygen and carbon or hydrogen. One such bond already exists in an ethanol molecule, whereas in petrol few or no such bonds exist.
No Petrol is a fossil fuel
No. Hydrogen fell out of favor in transportation after the Hindenburg. It's extremely volatile.
petrol is made from the fossil fuel oil
