Natural Gas (CH4) is the most ecological fuel of all, and one of the most abundant in nature. It is not obtained through a refinement process, but is an ecological fuel ready to use right from the source.
Natural Gas contains no impurities, sulphur, lead compounds or aromatic hydrocarbons, so it produces only very low levels of polluting emissions, with no odour, particulate matter or combustion residues.
The chemical composition of Natural Gas produces much less CO2 than other fuels and reduces ozone formation in the atmosphere.
The intrinsic properties of Natural Gas make it suitable for use in vehicles with no need for additives that may be harmful to human health. Also, it contains more energy than any other fuel (natural gas = 11,600 kcal/kg; petrol = 10,300 kcal/kg; diesel =10,200 kcal/kg).
Another important benefit is that Natural Gas is much easier and more economical to transport than other fuels, because after the initial cost of building a gas pipeline, it is very inexpensive to transport. Unlike other fuels, Natural Gas does not need to be transported in tanker trucks, which produce polluting emissions and contribute to traffic congestion, and therefore it helps reduce accident risk and pollution by heavy vehicle traffic.
The Natural Gas pipeline grid is underground, so it does not affect the landscape in the places it passes through.
