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
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
No Petrol is a fossil 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.
petrol is made from the fossil fuel oil
No. Hydrogen fell out of favor in transportation after the Hindenburg. It's extremely volatile.
Hydrogen because it only gives off water and is easy to make. Petrol is bad for environment and is running out Edit: Hydrogen usable as a fuel (H2) may be "easy to make" but the amount of energy you would consume in making the H2 would be greater than the amount of energy you would get back when you burned the H2.
Yes, you can use a fuel injector in a petrol engine.
