Question

What is the difference between hyrid diesel and hydrogen cars?

Answer 1

hybrids run on gas and/or electricity and hydrogen uses hydrogen fuel cells.

Answer 2

Both are fuel.

But one is diesel fuel, the other is hydrogen fuel.  Both are run in internal combustion engines.

Answer 3

Not much, since they both need fuel to run. Figure out how they create hydrogen.

Answer 4

1st of all let me say that "hybrid" just like when it relates to plants, animals, etc... means crossing two or more things together kind of like breeding. The same meaning for hybrid vehicules, two or more power sources run the car.

In your case a hybrid diesel(I'm assuming electric/diesel) would work in the same manner as a gas/electric like a Toyota Prius, only instead of regular gasoline it uses diesel. But there is still a battery/electric engine that runs when at lower speeds and the diesel engine kicks in at higher speeds. When the diesel engine is on it charges the battery and usually braking recharges it too. So the aid of the electric motor(at lower speeds when internal combustion engines are the least efficient) will improve fuel efficiency especially in city driving.

Hydrogen cars it depends on whether it is internal combustion hydrogen engine or a fuel cell. Most people are going to fuel cell route so I'll try to explain that. A fuel cell works by catalysis, separating the component electrons and protons of the reactant fuel[in this case hydrogen], and forcing the electrons to travel though a circuit, therefore converting it into electrical power.

By the definition of hybrid a car ran entirely on hydrogen wouldn't be considered a "hybrid" but of course it is still an alternative fuel vehicle.
