Natural Gas Vehicles (NGVs)
The United States currently has around 120,000 natural gas vehicles (NGVs) on its roads and over 15 million are used worldwide.
NGVs are gaining popularity
- More than 35 airports in the U.S. have NGVs in their own fleets or encourage use by private fleets operating on their premises.
- According to the American Public Transit Association, nearly one-fifth of all transit buses were run by compressed natural gas (CNG) or liquid natural gas (LNG) in 2011.
- The fastest growing NGV segment is waste collection and transfer vehicles. Almost 40 percent of the trash trucks purchased in 2011 were natural gas powered.
NGVs use compressed natural gas (CNG). The high methane content of natural gas makes it clean-burning which results in high engine efficiency and low emissions.
NGVs are also a major factor in reducing U.S. dependency on foreign oil. The United States spends about $1.7 billion a day for foreign oil. To reduce this spending, Congress has passed legislation creating incentives to move to non-petroleum fuels.
Because natural gas costs less than gasoline, an investment in a NGV can cut transportation costs dramatically. In fact, compressed natural gas across Alabama costs around 53 percent less than gasoline. Now is a great time to consider the benefits of switching to a natural gas vehicle.
NGVs have lower maintenance costs.
- Compared to gasoline engines, natural gas engines have virtually no carbon build-up.
- Less carbon build-up means less ring wear and longer engine life.
- NGVs require fewer oil changes and tune-ups because CNG burns cleaner than gasoline or diesel.
NGVs are safe.
- Compressed natural gas, unlike gasoline, dissipates into the air in the event of a spill.
- The fuel storage cylinders in NGVs are much stronger than gasoline fuel tanks.
NGVs are better for the environment.
- A dedicated NGV, which is a vehicle that can be fueled only by natural gas, produces little or no emissions that can harm the environment.
- Exhaust emissions from a typical NGV are much lower than those from gasoline-powered vehicles.
- Dedicated NGVs can reduce exhaust emissions of:
- Carbon monoxide by 70 percent
- Non-methane organic gas by 87 percent
- Nitrogen oxide by 87 percent
- Carbon dioxide by almost 20 percent.
- Natural gas, unlike gasoline, is not toxic or corrosive and will not contaminate ground water.
- In the U.S. alone, NGVs offset the use of nearly 360 million gallons of gasoline in 2011.
