It depends on how the hydrogen is obtained. If conventional power plants are used to hydrolize the water, that cars must take on the carbon footprint of the power sources (coal, oil, gas, nuclear, solar, hydro) This could be quite significant. Then there is the manufacturing of a distribution and fuelling network, the manufacture of the car etc.
No, hydrogen is just water in extreme temperatures.
Hydrogen is not a pollutant. It is controlled as a flammable gas in confined spaces.
people pollute by throwing trash on the ground other people pollute by not taking care of their car and letting smoke come out of it
the gas that comes out of the car is minorly poisonous
Honda has hydrogen car. Toyota has hydrogen car. gm is working on hydrogen car.
hydrogen
Burning hydrogen involves using heat to start combustion of hydrogen which oxidises hydrogen. The same goes for burning carbohydrates (metabolism). Oxidising hydrogen gives us H2O and, well, water isn't a pollutant.
because it does not pollute as much as a normal car
"No. A motor car is not good for the environment. It can pollute our air, which we need to breathe daily to live."
Compressed gaseous hydrogen.
Because the fuel is like gas and it can affect anybody...
It is illegal and will cause the vehicle to pollute the atmosphere.
