  • Hi! This is a great presentation! I was wondering where you got your information (the CNG schematic) on Slide 5, and the information and diagram for the refueling station on Slide 12. Thank you!

    1. 1. Compressed Natural Gas<br />Prepared by: Mary Rose V. Martinez<br />
    2. 2. What is CNG (Compressed Natural Gas)<br />It is a fuel substitute for gasoline (petrol), diesel and propane fuel<br />Where do we get CNG<br />It is drilled from the ground<br />What is the difference of CNG from LNG<br />CNG is gas stored as a gas at high pressure while Liquefied Natural Gas is in uncompressed liquid form<br />CNG has a lower cost of production and storage however it requires a much larger volume to store the same mass of gasoline or petrol and the use of very high amount of pressure (3000-4000 psi or 205-275 bar)<br />Is CNG safe<br />It is extremely safe when handled properly<br />It is less explosive than gasoline and harder to ignite<br />Overview<br />
    3. 3. CNG Market in the US<br />
    4. 4. CNG Market in the US<br />Major consumers of natural gas in the United States in 2009 included<br /><ul><li>Electric power sector – 6.9 trillion cubic feet (Tcf)
    5. 5. Industrial Sector – 6.1 Tcf
    6. 6. Residential Sector – 4.8 Tcf
    7. 7. Commercial Sector – 3.1 Tcf</li></li></ul><li>CNG Market in the US<br />
    8. 8. Powering more than ten million vehicles on the road today<br />150,000 of these are from US<br />Average growth of 3.7% per year since 2000 and with a global rate of 30.6% per year<br />About 1,100 natural gas fuel stations are to be found in the US<br />CNG costs about 40% less than gasoline, it emits up to 90% less emissions than gasoline*<br />* Emissions reductions may vary by pollutant and make/model of vehicle<br />CNG Market in the US<br />
    9. 9. CNG Distribution in the US<br />
    10. 10. Gas is distributed between and within states by 300,000 miles of transmission pipelines (see map from previous slide) <br />Most natural gas fueling stations all over the country dispense CNG which is either compressed on site of compressed off site and transported to the stations in tanks<br />CNG Distribution in the US<br />
    11. 11. There are federal incentives given to automakers to build more CNG vehicles<br />Incentives were also given to fuel retailers to encourage them to sell CNG<br />Samples:<br />For Consumers: provides an income tax credit for the purchase of new, dedicated alternative fuel vehicle of 50% of the incremental cost of the vehicle, plus an additional 30% if the vehicle meets certain tighter emission standards<br />For Fuel Retailers: Excise Tax Credit to the seller of CNG-provides for a tax credit of 50c per gasoline-gallon equivalent of CNG <br />Means to boost CNG Market in the US<br />
    12. 12. Daily prices change can be seen at<br />CNG Price on the Market<br />
    13. 13. Based on Clean Cities alternative fuel prices last January 2010. (Last report was conducted October 2010)<br /><ul><li>CNG is about 80cents less than gasoline on an energy-equivalent basis </li></ul>Average of Fuel Prices<br />
    14. 14. CNG Fueling Stations<br />1. Inlet Gas Line (from your local utility)<br />2. Inlet Dryer - used to reduce water content in the gas<br />3. Inlet Filtration - filters gas before compression<br />4. Gas Compressor - elevates inlet gas pressure from the gas utility to 5,000 psig.<br />5. Priority/Sequence Panel - allows for temperature compensation of the gas as well as directs gas flow to storage or to vehicle.<br />6. ASME Storage - stores high pressure gas to be dispensed into vehicles.<br />7. Gas Dispenser - dispenses gas into the vehicles and measures the amount transferred. <br />
    15. 15. CNG Fueling Station Locations<br />
    16. 16. Home Refueling<br />FuelMaker Corporation<br />Offers CNG home refueling appliance (Phill)<br />Can be installed inside a garage or outdoors<br />Offers automated time-fill CNG refueling at a rate of approximately 0.4 gasoline gallon equivalents per hour, appropriate for overnight refueling of commuter vehicles<br />Alternative Fueling Station <br />
    17. 17. Key market segments<br />Transit, Refuse, Airport (shuttles and taxis), Regional Trucking<br />Examples of vehicles suited for the CNG Valve include:<br />Light-duty (sedans, pick-up trucks, and SUVs)<br />Medium-duty (vans and shuttles)<br />Heavy-duty (school and transit buses, semi-trucks, waste disposal trucks, and delivery vehicles)o<br />Off-road vehicles (lawnmowers, forklifts, freight mounts, and street sweepers)<br />Usage of Solenoid Valves<br />
