Alternative Fuel Vehicles

Visit the Alternative Fuels and Advanced Vehicle Data Center to find research and data for fleet managers. Learn more about alternative fuel vehicles available in the US in the new
2012 Clean Cities Vehicle Buyer's Guide.

Natural Gas Resources

Natural Gas Vehicles: Websites and Resources Compiled By New Orleans Metro Region Louisiana Feb. 8, 2012


Incorporating NGVs into a fleet may require workforce training for technicians, drivers, and other professionals. The AFDC Alternative Fuels Technician Training website,, lists a number of organizations that offer training for alternative fuels and advanced vehicles. In particular, you may want to look into:

Vehicle Conversions

The following websites provide information about NGV conversions:

Legal Protocol for NGV Conversions

It is important to note that in the United States, all vehicle conversions (except pure battery electric vehicles) must meet current applicable U.S. Environmental Protection Agency (EPA) standards.  EPA instituted these standards to assure unimpaired emission control of motor vehicles throughout their useful life.  For information about these standards, see the EPA Alternative Fuel Conversion website,  Note the EPA List of Certified Clean Alternative Fuel Conversion Systems,, which includes EPA-certified conversions. This spreadsheet may be sorted by fuel type to identify EPA-certified compressed natural gas (CNG) and liquefied natural gas (LNG) conversions.  

Safety Regulations

Vehicle conversions that require the addition of heavy battery systems or additional fuel tanks that may alter a vehicle's center of gravity, payload capacity, or handling characteristics may need to be safety crash tested and certified to comply with Federal Motor Vehicle Safety Standards (FMVSS) and/or other NHTSA regulations. 

 When looking into vehicle conversions, there are a number of other considerations you may want to keep in mind, including financing (i.e. return on investment (ROI)), price of fuel and energy content/fuel economy (compared to conventional fuels), emissions (compared to conventional fuels), and infrastructure (i.e. station locations). Below are additional information on each of these considerations:


Cost is often a primary consideration when investing in alternative fuels. A few resources that directly address the ROI for CNG vehicles include:

Price of Fuel and Fuel Energy Content

The AFDC Alternative Fuels Price Report includes current and historic alternative fuels price data, which may be helpful as you consider vehicle conversion.  See for the most recent Alternative Fuel Price Report file.  Note that oftentimes, an important consideration when looking at the price of alternative fuels is energy content compared to conventional fuels.  The Alternative Fuel Price Report summarizes energy content considerations and includes conversion factors for fuels.  In addition, the AFDC Fuel Properties database allows users to compare fuel properties and characteristics of alternative and conventional fuels,


Generally, NGVs may produce significantly lower emissions of nitrogen oxides, particulate matter, and toxic and carcinogenic pollutants as well as carbon dioxide. The AFDC Emissions website,, is a great resource for researching the emissions of CNG and other alternative fuels, as is the AFDC Natural Gas Vehicle Emissions page,  You can also refer to the Argonne National Laboratory’s GREET Fleet Footprint Calculator,, to evaluate the life-cycle petroleum use and greenhouse gas emissions for various vehicle-types and fuels.

Fueling Station Infrastructure

CNG and LNG fueling infrastructure exist across the United States. For fueling station location data, please refer to the AFDC Fueling Station Locator,, which is searchable by both location and fuel type. The Advanced Search options enable you to target public, private, and/or planned fueling stations. 

 For information about developing new fueling station infrastructure, please refer to the AFDC Infrastructure Development website:  Specifically, for information on CNG station sizing considerations, costs, and expected return on investment, please also see pages 1-7 of the Business Case for Compressed Natural Gas in Municipal Fleets,, which uses the Clean Cities Vehicle and Infrastructure Cash-Flow Evaluation (VICE) Model to compare the costs as well as the payback period for a number of different CNG infrastructure development scenarios.  The relationship between fleet type/size and the end cost of the station can be seen on page 3-4 of the report.

 In addition, you can also refer your contact to the CNG Cost Calculator developed by the San Joaquin Valley Clean Cities Coalition,,  which allows users to estimate natural gas station owner costs per gasoline gallon equivalent of CNG sold.

 For information on station specifications, please see the following:

Incentives & Funding

For information regarding federal and state incentives that apply to CNG/LNG vehicles and infrastructure, please refer to the AFDC, Incentives and Laws page,, which contains summaries of state and federal incentives.  The Advanced Search options,, allow you to identify specific incentives by location, fuel-type, incentive-type, and user-type.
