CNG is a readily available alternative to gasoline that’s made by compressing natural gas to less than 1% of its volume at standard atmospheric pressure. Consisting mostly of methane, CNG is odorless, colorless and tasteless. It's drawn from domestically drilled natural gas wells or in conjunction with crude oil production. Natural Gas powers more than 12 million vehicles on the road today.
Dedicated Natural Gas Vehicles are designed to run on natural gas only.
Bi-Fuel Vehicles can run on both CNG or gasoline. Bi-Fuel vehicles allow users to take advantage of the wide-spread availability of gasoline or diesel but use a cleaner, more economical alternative when natural gas is available.
Natural Gas Vehicles are not available on a large scale in the U.S.—only a few models are currently offered for sale. However, conventional gasoline and diesel vehicles can be retrofitted for CNG.
Benefits of CNG
Carpool Lane - Dedicated CNG Vehicles in Utah qualify for a Clean Fuel "C" Decal which allows you to drive in the carpool lane solo. (Click Here For More Info & Application)
Saves Money - CNG has historically been cheaper than traditional fuels (gasoline/diesel). In Utah, the average cost is $1.68 a GGE (Gasoline Gallon Equivalent)
Bi-Fuel - Change to either fuel with the push of a control switch.
Domestic Fuel - CNG isn’t dependent on foreign oil. That means we’re not affected by their constant price increases! You’ll save even more in the future, because gasoline will continue to rise faster than natural gas.
It’s Environmentally Friendly - There are fewer emissions and hydrocarbons are virtually eliminated.
Engine Lasts Longer, Runs Cleaner, Quieter - No carbon deposits which create friction and engine wear. No carbon deposits also means no clogging and dirtying of the plugs. Even the Catalytic Converter lasts longer, with less engine noise because of the higher octane of natural gas.
Fewer Oil Changes - Carbon deposits which dirty the engines oil are eliminated.
Diesel Power Increased - Unlike gasoline engines, diesel’s also benefit from a dramatic power increase, due to the 60/40 blend. So if you’re used to pulling heavy loads, you not only get better power, you save fuel costs while doing so.
Safety of CNG
The fuel storage cylinders used in CNG vehicles are much stronger than gasoline fuel tanks. The design of natural gas cylinders is subjected to a number of federally required "severe abuse" tests, such as heat and pressure extremes, gunfire, collisions and fire testing.
Natural Gas Fuel systems are "sealed," which prevents spills or evaporative losses. Even if a leak were to occur in a fuel system, the natural gas would dissipate up into the atmosphere, unlike gasoline which in the event of a leak or accident, pools on the ground, creating a fire hazard.
Natural gas has a high ignition temperature, about 1,200° Fahrenheit, compared with about 600° Fahrenheit for gasoline. It also has a narrow range of flammability, that is, in concentrations in air below about 5% and above about 15%, natural gas will not burn. The high ignition temperature and limited flammability range make accidental ignition or combustion of natural gas unlikely.
Natural gas is not toxic or corrosive and will not contaminate ground water.
