The use of natural gas vehicles, liquid or gaseous, offers savings in two aspects:
- First, the cost associated with the compressed natural gas is significantly lower than the cost of the diesel and petrol, second, due to the characteristics of natural gas which provides a clean burning, the need for maintenance becomes reduced.
- In environmental terms, the GN is the cleanest energy source of all alternative fuels.
Apart from these factors, the VGNs (natural gas vehicles) also emit significantly lower amounts of greenhouse gases and toxins in relation to petrol or diesel vehicles.
The NG fueled vehicles are as safe as vehicles operating on conventional fuels. Natural gas, unlike liquid fuels and LPG, dissipates into the atmosphere in case of accident, avoiding fire hazards created by pools of petrol, diesel or LPG on the floor.
