CNG Resources

 

Payback Calculator

With so many benefits of transitioning your fleet to CNG, the one benefit all fleet operators agree is important is the long-term savings offered by NGV. Not all applications make sense right now, such as vehicles that use a relatively lower volume of fuel. But most fleet applications do make sense. To find out about your fleet simply enter the premium cost of the NGV fuel system, the number of vehicles you operate in that class and the likely cost of CNG and for Diesel or gasoline you use in your fleet.

Temperature & Pressure

Liquid fuels such as gasoline and Diesel hold about the same volume of fuel across a broad range of conditions. Like most gaseous molecules, CNG volume expands in higher temperature conditions and contracts in lower temperature conditions. As a result, a CNG vehicle tank that can hold 45 GGE at 3600 psi at 70 degrees F may only hold 75% (or less) of that volume on a 95 degree day. Temperature compensated dispensers make sure vehicles get the best fill possible without lifting safeties on the vehicle, balancing maximum fuel volume on the vehicle while preventing otherwise vented and wasted fuel.

Emissions Comparisons

Natural gas burns cleaner than conventional gasoline or diesel due to its lower carbon content. When used as a vehicle fuel, it can offer life cycle greenhouse gas (GHG) emissions benefits over conventional fuels, depending on vehicle type, drive cycle, and engine calibration. In addition, using natural gas may reduce some types of tailpipe emissions.
