Natural Gas Basics
Natural gas powers more than 100,000 vehicles in the United States and roughly 11.2 million vehicles worldwide. Natural gas vehicles (NGVs) are a good choice for high-mileage fleets—such as buses and taxis—that are centrally fueled or operate within a limited area. The advantages of natural gas as an alternative fuel include its domestic availability, widespread distribution infrastructure, low cost compared with gasoline and diesel, and clean-burning qualities.
What is natural gas?
Natural gas is an odorless, nontoxic, gaseous mixture of hydrocarbons—pre- dominantly methane (CH4). Because it is a gas, it must be stored onboard a vehicle in either a compressed gaseous or liquefied natural gas is typically stored in a tank at a pressure of 3,000 to 3,600 pounds per square inch. Liquefied natural gas is cooled and stored in its liquid phase at -260°F in special insulated tanks. Natural gas is sold in units of gasoline or diesel gallon equivalents based on the energy content of a gallon of gasoline or diesel fuel.
