NGV (Natural Gas for Vehicles) is an alternative vehicle fuel that uses compressed natural gas (CNG) as a cleaner alternative transportation. It can be used in all types of transportation applications including vehicles, buses, trucks, cranes, vans, and also in forklifts.
According to the industry group NGV Global, there are more than 15.2 million natural-gas vehicles on the road worldwide.
A regular gasoline-powered car averages 32 miles per gallon while a CNG-powered car averages 43 miles per gallon.
Advantages of NGVs
For the average motorist, there are good reasons to switch.
- Safety: Lighter-than-air natural gas dissipates in an accident — a safer scenario than flammable liquid fuel.
- Efficiency: While similar models of natural-gas and gasoline-powered cars get the same miles per gallon, you’ll spend a lot less filling up the tank. Natural gas is about half the price of gasoline. You’ll also need to change the car’s oil less frequently because of the cleaner-burning fuel.
- Home advantage: Eighty percent to 90 percent of the natural gas we use comes from domestic sources, according to the U.S. Energy Information Administration.
- Similar to driving a gasoline-powered car: ConsumerReports.org says drivers won’t notice any difference except that “acceleration is typically slower.”
Disadvantages of NGVs
Before you run out to buy an NGV, consider these limitations.
- Limited options: There are only several car models is NGV- installed.
- More expensive: Cars with NGV- installed are usually more expensive than gasoline-powered.
- Limited fueling stations: There are about 1,000 natural gas fueling stations across the U.S., but only 536 are available for public use, according to the U.S. Department of Energy’s Alternative Fuel Data Center website — and the majority is clustered around major metropolitan hubs.
- The gas tank installation is expensive: The NGV tank installation costs range between RM 3000 and above.
- Natural gas is a nonrenewable fossil fuel: The U.S. Energy Information Administration projects state that there’s enough natural gas to last them about 90 years.
