The natural gas contained of fossil fuels, in this gas is methane. Methane is a hydrocarbon gas that is an organic compound, these gases and oils mixed together make the cleanest burning alternative fuel (fueleconomy.gov,2007) for cars and trucks. Hydrogen gas also does not exude air pollutants “it produces only nitrogen oxides (NOx) when burned in ICEs.” (fueleconomy.gov,2007) ICEs being defined as Internal Combustion Engines, these engines specifically function on diesel fuels. Liquefied petroleum gas is another fossil fuel that can produce less amounts of harmful emissions. There are a limited amount of cars that can operate on LPG fuels, some vans and other small cars can operate on LPG fuels, but the vehicles must be converted to use propane fuels.
After reviewing the possible alternative fuels and the benefits of operating a vehicle on fuels with less probability of pollution in the air could give hope for the future and the ozone
