Natural gas can be used in all classes of vehicles – motorcycles, cars, vans, light and heavy duty trucks, buses, lift trucks, locomotives, even ships and ferries. Natural gas can be used either by converting an existing gasoline or diesel engine, or by using a purpose built natural gas engine.
Benefits of natural gas vehicles include:
Reduced particulate and NOx (Nitrogen Oxides) emissions
Reduced greenhouse gas emissions
Widespread availability of natural gas
Can be derived from renewable sources (biogas)
Applicable to all vehicle classes
Minimal processing or refining requirements
Safer than most liquid fuels
Can be refueled at home or workplace
Noise reductions of as much as 50%
Reduced engine wear
With these benefits, its easy to see why natural gas vehicle (NGV) numbers have more than doubled in the last 5 years alone. There are currently more than 15 million NGVs worldwide (December 2011) and NGV Global is projecting that this will increase at least five-fold, to more than 65 million natural gas vehicles by 2020.
