Greater Houston NGV Alliance is focused on developing new and expanding natural gas transportation markets, refueling stations and raising awareness of natural gas vehicles to both policy makers and general public.http://www.houstonngvalliance.org/
Facts About NGV
What are NGVs?
Natural gas vehicles (NGVs) look like any other vehicle. The difference is that NGVs operate on natural
gas as opposed to the fuel we typically pump into our vehicles’ tanks. NGVs typically use one of two
varieties of natural gas: compressed natural gas (CNG) or liquefied natural gas (LNG). Dedicated NGVs
are equipped to run exclusively on natural gas. Bi-fuel NGVs can run on either natural gas or gasoline.
Dual-fuel vehicles run on natural gas and use diesel for ignition assistance.
Who’s driving NGVs?
Basically anyone who’s looking to reduce fuel costs and lower emissions. While increasing numbers of
environmentally sensitive consumers are purchasing NGVs, the largest market currently for these types of
vehicles are fleets. In fact, 40% of buses on order are natural gas vehicles. You’ll also find NGVs among
many other types of fleets, including taxi fleets, courier and delivery fleets, government and police fleets,
community fleets, and trades and commercial fleets. Consumers and fleets also have the option of
converting existing light- or heavy-duty gasoline or diesel vehicles to natural gas using certified installers.
Are they safe?
NGVs are as safe as any gasoline-powered vehicle. There are over 11 million NGVs in use around the
world, and the safety record is excellent. NGVs in the United States meet the same safety standards as
gasoline and diesel vehicles and their fuel tanks are strong and puncture resistant.
How much do NGVs cost?
Light-duty NGVs cost from $5,000 to $7,000 more than comparable gasoline vehicles, and heavy-duty
NGVs can cost $30,000 or more than comparable diesel vehicles. The price depends on the fuel-tank
capacity and whether the vehicle is equipped by the manufacturer or converted to run on natural gas.
However, government incentives are available to offset NGV costs
NGVs received some of the highest rankings for environmental performance. Using natural gas is one of
the best ways to reduce harmful air pollutants. That’s because natural gas burns cleaner than gasoline
and other alternative fuels, reducing tailpipe emissions by up to 95%. In addition, factory-built NGVs
produce emission levels lower than any other fuel except hydrogen. In fact, the Environmental Protection
Agency (EPA) has noted natural gas version of the Honda Civic, the GX, as being the “cleanest internal
combustion vehicle on Earth”.
Shown below are some additional environmental benefits of NGVs:
Reduces carbon monoxide emissions 70-90%
Reduces carbon dioxide emissions 20-30%
Reduces nitrogen oxide emissions 75-95%
Potentially reduces non-methane hydrocarbon emissions 50-75%
Emits fewer toxic and carcinogenic pollutants
Emits little or no particulate matter
Eliminates evaporative emissions
Is it easy to fuel an NGV?
Yes. CNG vehicles are fueled with easy-to-use, pressure-sealed dispensers. CNG fueling stations can
be configured to fuel vehicles at various rates. Time-fill stations fuel parked vehicles overnight, taking
advantage of off-peak electricity rates and smaller compression equipment. Fast-fill stations fill vehicles
rapidly using larger compression equipment and high-pressure gas-storage systems.
