Natural Gas Basics
Natural gas, a domestically produced gaseous fuel, is readily available through the utility infrastructure.
Natural Gas is a hydrocarbon mixture predominantly composed of methane (CH4). Lesser components of this gaseous mixture include ethane, propane, butane, nitrogen, helium, carbon dioxide, hydrogen sulfide and water vapor, which are removed prior to use. It is a nontoxic, non-corrosive, non carcinogenic fuel with significantly less harmful tailpipe emissions.
A majority of natural gas is a fossil fuel that is drawn from wells or extracted in conjunction with crude oil production. Natural gas can also be mined from subsurface porous rock reservoirs through extraction processes, such as hydraulic fracturing. Natural gas from renewable sources (biogas) is an emerging fuel, produced from decaying organic materials (waste from plants, landfills, wastewater and livestock).
The benefits of natural gas and propane autogas vehicles have been widely established and publicized. These include:
