Natural gas is a domestically produced alternative fuel and is readily available to end users through the utility infrastructure. It can produce significantly fewer harmful emissions than gasoline or diesel when used in natural gas vehicles.
Natural gas is a mixture of hydrocarbins, predominantly methane (CH4). As delivered through the pipeline system, it also contains hydrocarbons such as ethane, propane and other gases such as nitrogen, helium, carbon dioxide, hydrogen sulfide, and water vapor.
Natural gas has a high octane rating and excellent properties for spark-ignited internal combustion engines. It is non-toxic, non-corrosive, and non carcinogenic. It presents no threat to soil, surface water, or groundwater.
Natural gas accounts for approximately one quarter of the energy used in the United States. Of this, about one third goes to residential and commercial uses, one third to industrial uses, and one third to electric power production. Only about one tenth of one percent is currently used for transportation fuel.
CNG and LNG are considered alternative fuels under the Energy Policy Act of 1992. The horsepower, acceleration, and cruise speed of NGVs are comparable with those of equivalent conventional vehicles. And, compared with conventional diesel and gasoline vehicles, NGVs can produce some emissions benefits.
There are three types of NGVs:
Dedicated: These vehicles are designed to run only on natural gas.
Bi-Fuel: These vehicles have two separate fueling systems that enable them to run on either natural gas or gasoline.
Dual-Fuel: These vehicles are traditionally limited to heavy-duty applications, have fuel systems that run on natural gas, and use diesel fuel for ignition assistance.
America's Natural Gas Alliance (ANGA)
Representing North America's leading independent natural gas exploration and production companies, America's Natural Gas Alliance (ANGA) works with industry, government and customer stakeholders to promote increased demand for and continued availability of our nation's abundant natural gas resource for a cleaner and more secure energy future.
American Gas Association
Founded in 1918, the American Gas Association (AGA) represents more than 200 local energy companies that deliver clean natural gas throughout the United States. Today, more than 68 million residentail, commercial and industrial customers across the nation receive their reliable, affordable supplies of natural gas from AGA members - and natural gas meets almost a quarter of America's energy needs.
