FAQ

FAQ - Natural Gas Conversions

What type of warranties are offered on the CNG conversion and installation?

There is a 2-year manufacture product warrantee, and a 12-month Greenline Fuel Corp labor guarantee.

Do we offer fleet discounts?

Yes, this will be done by custom quotes and arrangements.

What is CNG or NGV?

CNG (compressed natural gas) or NGV (natural gas for vehicle) natural gas is a mixture of gases, methane (85 to 98 %).

Is LPG the same as CNG?

NO! LPG is a mixture of gases, butane and propane stored in a liquid state. Propane is a low-pressure liquefied gas and CNG is high-pressure compressed natural gas. The storage pressures are between 8 to 15 bars (116 psi to 217,5 psi) for propane and 200 to 250 bars for CNG (3000 psi and 3600 psi)

Is it possible to convert any vehicle?

Practically 100% of gasoline vehicles and most diesel vehicles can be converted.

What is the efficiency of one standard cubic meter of CNG?

CNG Conversions typically will see a 10% decrease in performance. This is in power and fuel economy. In conclusion, 1Sm3 = 1,10 gasoline liter.

Why is CNG Environmental Friendly?

Because vehicles running on CNG produce less contaminating exhaust gases (emissions) than those vehicles running on petrol or gas-oil. CNG vehicles produce 20-30% less greenhouse gas emissions than comparable gasoline vehicles.

Is it possible to convert electronic fuel injection vehicles?

Yes

Which is the best cylinder for my car?

The cylinder to be chosen depends on the mile range you desire and the free space in your vehicle. Our tank sizes range from 6.7 to 13.6 equivalent US gallon. You can do multiple tanks to increase range.

Is CNG more dangerous than petrol?

No, clean burning CNG is safer. One of the reasons is that natural gas is lighter than air. It is difficult to have dangerous concentration of natural gas in the case of leakage because it dissipates rapidly. The tanks are also designed to release air slowly, never exploding, even from several rounds from a high powered rifle.

Is it possible to use any kind of cylinder to store CNG?

NO! ONLY CYLINDERS FOR HIGH PRESSURE CNG STORAGE CAN BE USED. TANKS AND CYLINDERS HAVE EXPIRATION DATES AND NEVER SHOULD BE USED IF EXPIRED. WE RECOMMEND NEVER USING USED TANKS UNLESS INSPECTED BUY CERTIFIED INDIVIDUALS.

Is there major the maintenance work on a CNG Conversion?

No, the original maintenance program must be followed. There are many advantages that exist over gasoline, for example: the motor, and the motor oil life will increase and your car will run cleaner.

Is there enough US supply for American to use natural gas?

Absolutely. A recent article by USAToday states that America has 118 years of resources under our own soil, NOT foreign. If we can make at least a partial transition, we can prevent sending billions of dollars to foreign nations. Check our news section for other information on this topic.

Where am I going to fill up? Are there any places where I live?

You can look at our station locator to see if there are any locations near you. There are several major companies that are purchasing compressors to be able to deliver CNG, but it will take some time to develop this infrastructure so everyone will be able to take advantage of this resource. There is also ongoing legislation that will help to subsidise these costs, as well as other incentives.

I've heard of tax incentives in having a CNG vehicle. What's that about?

Depending on your state, you can receive from $1,000-$18,500 to offset the cost of the conversion. You may also receive a tax credit if you have a Phill station installed at home. You can also become eligible to use the HOV lane and free parking.

What Is CNG?

Basics

Compressed Natural Gas (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 gas wells or in conjunction with crude oil production.

Natural gas powers more than ten million vehicles on the road today. Unfortunately, only 150,000 of these are being used today in the U.S. The average growth rate in the U.S. shows a 3.7% per year since 2000, as contrasted with a booming global growth rate of 30.6% per year. Expanding the numbers of CNG fueling stations would allow for the increase of CNG vehicles on U.S. roads. There are 12,000 around the world, yet the U.S. claims about 1,100. More stations will continue to be built in America in the coming years. However, as gasoline prices continue to rise, American interest in CNG is rising accordingly. And with good reason – CNG costs about 40% less than gasoline, it emits up to 90% less emissions than gasoline,* there’s an abundant supply and it’s produced right here in America. So it’s affordable, clean, abundant and American. *Emissions reductions may vary by pollutant and make/model of vehicle.

Safety

When used as an automobile fuel, compressed natural gas (CNG) is stored onboard vehicles in tanks that meet stringent safety requirements. 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. Natural gas is not toxic or corrosive and will not contaminate ground water.

Focus on Operations

It takes a great deal of effort and expertise to locate and extract natural gas. Located miles beneath the surface, high-tech engineering practices are coordinated with environmental guidelines to bring up the gas and process it in the safest manner possible. This can take months to complete. The processes employed for natural gas exploration and production can be found on this page. Please look over these fact sheets for detailed information on horizontal drilling, hydraulic fracturing and water usage.

History

The history of compressed natural gas (CNG) as a transportation fuel dates back to World War II. Natural gas vehicles are a proven technology that have been enhanced and refined over the years into a convenient and extremely safe method of transportation. Daily use of natural gas vehicles can be found throughout the United States in a variety of applications.
