Building a Business Case for Compressed Natural Gas in Fleet Applications
3/19/2015
Abstract: Natural gas is a clean-burning, abundant, and domestically produced source of energy. Compressed natural gas (CNG) has recently garnered interest as a transportation fuel because of these attributes and because of its cost savings and price stability compared to conventional petroleum fuels. The National Renewable Energy Laboratory (NREL) developed the Vehicle Infrastructure and Cash-Flow Evaluation (VICE) model to help businesses and fleets evaluate the financial soundness of CNG vehicle and CNG fueling infrastructure projects.

Clean Cities Alternative Fuel Price Report, January 2015
3/17/2015
The Clean Cities Alternative Fuel Price Report for January 2015 is a quarterly report on the prices of alternative fuels in the U.S. and their relation to gasoline and diesel prices. This issue describes prices that were gathered from Clean Cities coordinators and stakeholders between January 1, 2015 and January 15, 2015, and then averaged in order to determine regional price trends by fuel and variability in fuel price within regions and among regions. The prices collected for this report represent retail, at-the-pump sales prices for each fuel, including Federal and state motor fuel taxes.
Table 1 reports that the nationwide average price (all amounts are per gallon) for regular gasoline has decreased $1.04 from $3.34 to $2.30; diesel decreased 71 cents from $3.77 to $3.06; CNG price decreased 5 cents from $2.16 to $2.11; ethanol (E85) decreased 67 cents from $2.88 to $2.21; propane decreased 16 cents from $3.08 to $2.92; and biodiesel (B20) has decreased 63 cents from $3.81 to 3.18.
According to Table 2, CNG is $.19 less than gasoline on an energy-equivalent basis, while E85 is $0.82 more than gasoline on an energy-equivalent basis.

Clean Cities Alternative Fuel Price Report, October 2014
12/23/2014
The Clean Cities Alternative Fuel Price Report for October 2014 is a quarterly report on the prices of alternative fuels in the U.S. and their relation to gasoline and diesel prices. This issue describes prices that were gathered from Clean Cities coordinators and stakeholders between October 1, 2014 and October 15, 2014, and then averaged in order to determine regional price trends by fuel and variability in fuel price within regions and among regions. The prices collected for this report represent retail, at-the-pump sales prices for each fuel, including Federal and state motor fuel taxes.
Table 1 reports that the nationwide average price (all amounts are per gallon) for regular gasoline has decreased 36 cents from $3.70 to $3.34; diesel decreased 14 cents from $3.91 to $3.77; CNG price decreased 1 cent from $2.17 to $2.16; ethanol (E85) decreased 35 cents from $3.23 to $2.88; propane increased 1 cent from $3.07 to $3.08; and biodiesel (B20) has decreased 17 cents from $3.98 to 3.81.
According to Table 2, CNG is $1.18 less than gasoline on an energy-equivalent basis, while E85 is $0.73 more than gasoline on an energy-equivalent basis.

Geography of Existing and Potential Alternative Fuel Markets in the United States
11/3/2014
When deploying alternative fuels, it is paramount to match the right fuel with the right location, in accordance with local market conditions. We used six market indicators to evaluate the existing and potential regional market health for each of the five most commonly deployed alternative fuels: electricity (used by plug-in electric vehicles), biodiesel (blends of B20 and higher), E85 ethanol, compressed natural gas (CNG), and propane. Each market indicator was mapped, combined, and evaluated by industry experts. This process revealed the weight the market indicators should be given, with the proximity of fueling stations being the most important indicator, followed by alternative fuel vehicle density, gasoline prices, state incentives, nearby resources, and finally, environmental benefit. Though markets vary among states, no state received 'weak' potential for all five fuels, indicating that all states have an opportunity to use at least one alternative fuel. California, Illinois, Indiana, Pennsylvania, and Washington appear to have the best potential markets for alternative fuels in general, with each sporting strong markets for four of the fuels. Wyoming showed the least potential, with weak markets for all alternative fuels except for CNG, for which it has a patchy market. Of all the fuels, CNG is promising in the greatest number of states--largely because freight traffic provides potential demand for many far-reaching corridor markets and because the sources of CNG are so widespread geographically.

Clean Cities 2013 Annual Metrics Report
10/20/2014
Each year, the U.S. Department of Energy asks its Clean Cities program coordinators to submit annual reports of their activities and accomplishments for the previous calendar year. Data and information are submitted via an online database that is maintained as part of the Alternative Fuels Data Center (AFDC) at the National Renewable Energy Laboratory (NREL). Coordinators submit a range of data that characterize the membership, funding, projects, and activities of their coalitions. They also submit data about sales of alternative fuels, deployment of alternative fuel vehicles (AFVs) and hybrid electric vehicles (HEVs), idle-reduction (IR) initiatives, fuel economy activities, and programs to reduce vehicle miles traveled (VMT). NREL analyzes the data and translates them into petroleum-use reduction impacts, which are summarized in this 2013 Annual Metrics Report.

Costs Associated with Compressed Natural Gas Vehicle Fueling Infrastructure
9/9/2014
This document is designed to help fleets understand the cost factors associated with fueling infrastructure for compressed natural gas (CNG) vehicles. It provides estimated cost ranges for various sizes and types of CNG fueling stations and an overview of factors that contribute to the total cost of an installed station. The information presented is based on input from professionals in the natural gas industry who design, sell equipment for, and/or own and operate CNG stations.
