  • Americans spend about $1 billion each day on foreign oil. Many of the countries that supply foreign oil to the U.S. are converting their vehicle fleets to NGVs so that they can sell us their oil. Right now there are about 140,000 NGVs in the U.S. 12 million NGVs currently worldwide, with that number expected to increase to 28.7 million by 2015.
  • http://www.naturalgas.org/environment/naturalgas.asp Natural gas can be used in the transportation sector to cut down on these high levels of pollution from gasoline and diesel powered cars, trucks, and buses. In fact, according to the EPA, compared to traditional vehicles, vehicles operating on compressed natural gas have reductions in carbon monoxide emissions of 90 to 97 percent, and reductions in carbon dioxide emissions of 25 percent. Nitrogen oxide emissions can be reduced by 35 to 60 percent, and other non-methane hydrocarbon emissions could be reduced by as much as 50 to 75 percent. In addition, because of the relatively simple makeup of natural gas in comparison to traditional vehicle fuels, there are fewer toxic and carcinogenic emissions from natural gas vehicles, and virtually no particulate emissions. Thus the environmentally friendly attributes of natural gas may be used in the transportation sector to reduce air pollution.
  • Although CNG is a flammable gas, it has a narrow flammability range, making it an inherently safe fuel. Strict safety standards make CNG vehicles as safe as gasoline-powered vehicles. In the event of a spill or accidental release, CNG poses no threat to land or water; it is nontoxic. CNG also disperses rapidly, minimizing ignition risk relative to gasoline. Natural gas is lighter than air and will not pool as a liquid or vapor on the ground. Nevertheless, leaks indoors may form a flammable mixture in the vicinity of an ignition source.
  • The Clean Cities Alternative Fuel Price Report is a quarterly report so April 2013 is the most current version. Clean Cities is a program within the Energy Efficiency and Renewable Energy branch of the U.S. DOE
  • How much natural gas does the United States have and how long will it last? EIA estimates that there are 2,203 trillion cubic feet (Tcf) of natural gas that is technically recoverable in the United States. At the rate of U.S. natural gas consumption in 2011 of about 24 Tcf per year, 2,203 Tcf of natural gas is enough to last about 92 years How much natural gas is consumed (used) in the U.S.? In 2012, the U.S. consumed approximately 25.46 trillion cubic feet (Tcf) of natural gas in seven consumer end-uses. Electric power generation: 9.14 Tcf (36%) Industrial: 7.10 Tcf (28%) Residential: 4.18 Tcf (16%) Commercial: 2.90 Tcf (11%) Lease and plant fuel consumption: 1.39 Tcf (5%) Pipeline and distribution: 0.71 Tcf (3%) Vehicle fuel: 0.03 Tcf (<1%)
  • The national natural gas distribution system is a mature system that has been providing gas supplies for decades. The inset map shows the U.S. natural gas pipe line distribution network. The red lines are intra state and the blue are interstate. (Source is the EIA Office of Oil & Gas, Natural Gas Division, Gas Transportation Information System) The technology in vehicles has been in use for decades as well.
  • Fuel savings based upon an assumed 4 mpg fuel economy, diesel price = $4/gal and CNG price of $2/gal
  • Two primary options exist with respect to fueling stations for fueling CNGVs, time fill and fast fill. Fleets that operate out of a central location, during a discreet window of time, and then remain idle for a period of time make good candidates for time fill. Time fill stations typically fill directly from the compressors, and don’t deplete storage.
  • Vehicles that have less predictable fueling schedules and/or do not have the flexibility to fill over an extended period of time require access to a fast fill station. Fast fill CNG station fill rates are synonymous to current day petro fuel filling stations (8-10 gal/min). Fast fill stations are typically sized to fill from storage to accommodate peak demands, with compressors appropriately sized to replenish storage and supplement demand.
  • The Sevier County Utility District (SCUD) is leading the way in an initiative to adopt CNG as a transportation fuel in the Sevier County area. As a first step, SCUD is constructing a CNG fueling station at the local office in Sevierville, TN. This fueling station will service the SCUD fleet as well as being open to the general public for fueling private vehicles. Additionally, SCUD plans to retrofit their entire service fleet (35 vehicles) to be fueled with CNG over the next few years. SCUD has identified a number of other entities in the Sevier County area that are logical candidates for fleet conversion to CNG. The cities of Gatlinburg, Pigeon Forge, and Sevierville all have a number of trash trucks, public transportation trolleys, school buses, and public works vehicles that represent a large fuel usage component in the area. The evolution of this market in the Sevier County area will create a significant demand for conversion kits, new CNG vehicles, maintenance shops capable of servicing CNG vehicles, fueling equipment, fueling equipment service capabilities, and technological improvements in all of the service areas associated with this industry. SCUD recognizes that as the supplier of natural gas to the Sevier County service area, they play a critically important and central role in this initiative. SCUD also understands that the transformation from gasoline and diesel to CNG as the primary transportation fuel is a long term initiative and they are committed to being a leading organization in this endeavor in the years ahead. Proactive initiatives such as this will propel the CNG market forward in Sevier County as well as serve as a model for other counties across Tennessee and the rest of the country.
