INTRODUCTION:-
Zero
emission vehicles are those which is free from polluting elements while the
engine of the vehicle is in running condition. There are certain vehicle which
comes in the category of zero emission vehicle. This also includes electric
vehicle, bicycle, gliders etc.
The vehicle uses hydrogen energy or hydrogen
fuel cell also comes in the category of zero-emission vehicle because hydrogen
energy is a type of clean energy. Although it is not totally emission free
energy but it only affects the place where the power generation takes place.
There are
many types of pollutants which needs to be controlled in a zero emission
vehicle. These are oxides of nitrogen, carbon mono oxide, carbon dioxide, lead
etc.
In some
cases we just shift the location of the gases to emit. For example if we use
electricity or natural gas, the gases will emit in the premises where the power
generation is going on. After that, this energy is transferred to the vehicle.
WELL TO WHEEL EMISSION IN ELECTRIC CARS:-
A term
related to zero emission vehicles is important that is called well to wheel
emissions. When the electrical energy is used to provide the power, the
batteries will be used which needs to be change periodically or frequently.
In the
electricity generation the emission of harmful gases like carbon dioxide,
greenhouse gases etc. takes place. But it can be controlled by using
appropriate method of energy generation i.e. renewable energy resources. If we
generate the electricity through the methods like solar energy, wind energy
etc. the emission will be very less, this theory is called ell to heel
emission.
