  3. Storage

  4. CNG Storage Vessels 3 Distinct Categories • Plain Metal Cylinder • Fiber Wrapped Metal Cylinder • Composite

  5. The CNGV Image: http://www.cng.cz/miranda2/export/sites/www.cng.cz/en/natural_gas/Natural_Gas_Vehicles/design_imgs/04_4_01a_eng.jpg

  6. Refueling • Slow Fill • Fuelmaker • 0.46 gge/hr • Residential Natural Gas • Fast Fill • About the same fill rate as conventional gas stations • Few and far between

  7. Fast Fill CNG Stations • 777 Stations • 150:1 Image:http://www.afdc.energy.gov/afdc/fuels/natural_gas_locations.html

  8. Combustion and Emissions • 130 Octane rating • 12.5:1 • Emissions reduction based on Gasoline Engines • NOx by 30-60% • CO by 90-97% • CO2 by 25% • NMHC 50-75%

  9. Safety • Relief Valves • Shutoff Valves • Tank Design • Buoyancy of CNG • CNG LEL 5% • UEL 15% Images: http://www.sealancers.org/Articles/tanks/tank3.jpg (top left), Powertech (top left, bottom)
