Guideline for Determining the Modifications Required for Natural Gas Vehicle Maintenance Facilities
5/17/2017
The growth of natural gas vehicle (NGV) fleets in recent years has increased the need for additional gaseous fuel maintenance facilities across the country. The guidelines describe the modifications necessary for existing liquid fuel maintenance facilities to service compressed and liquefied NGVs. Additionally, the document outlines the basic national codes and the rationale and assumptions used to develop these codes.

Clean Cities Alternative Fuel Price Report, April 2017
5/17/2017
The Clean Cities Alternative Fuel Price Report for April 2017 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 April 1, 2017 and April 17, 2017, 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 2 reports that the nationwide average price (all amounts are per gallon) for regular gasoline has increased 6 cents from $2.32 to $2.38; diesel decreased 3 cents from $2.58 to $2.55; CNG price increased 4 cents from $2.11 to $2.15; ethanol (E85) increased 7 cents from $2.04 to $2.11; propane increased 3 cents from $2.80 to $2.83; and biodiesel (B20) has decreased 8 cents from $2.57 to 2.49.
According to Table 3, CNG is $.23 less than gasoline on an energy-equivalent basis, while E85 is $0.36 more than gasoline on an energy-equivalent basis.

Clean Cities 2015 Annual Metrics Report
12/28/2016
The U.S. Department of Energy's (DOE's) Clean Cities program advances the nation's economic, environmental, and energy security by supporting local actions to cut petroleum use and greenhouse gas (GHG) emissions in transportation. A national network of nearly 100 Clean Cities coalitions, whose territory covers 80% of the U.S. population, brings together stakeholders in the public and private sectors to deploy alternative and renewable fuels, idle-reduction (IR) measures, fuel economy improvements, and new transportation technologies as they emerge. Each year, DOE asks Clean Cities coordinators to submit annual reports of their activities and accomplishments for the previous calendar year. Progress reports and information are submitted online as a function of the Alternative Fuels Data Center (AFDC) at the National Renewable Energy Laboratory (NREL). Coordinators report a range of information that characterizes the membership, funding, projects, and activities of their coalitions. They also document activities in their region related to the development of refueling/charging infrastructure, sales of alternative fuels; deployment of alternative fuel vehicles (AFVs), plug-in electric vehicles (PEVs), hybrid electric vehicles (HEVs), and plug-in hybrid electric vehicles (PHEVs); idle reduction initiatives; fuel economy improvement activities; and programs to reduce vehicle miles traveled (VMT). NREL analyzes the data and translates them into petroleum-use and GHG emission reduction impacts, which are summarized in this report.

Low-Carbon Natural Gas for Transportation: Well-to-Wheels Emissions and Potential Market Assessment in California
12/1/2016
This report improves on the understanding of the long-term technology potential of low-carbon natural gas (LCNG) supply pathways by exploring transportation market adoption potential through 2035 in California. Techno-economic assessments of each pathway are developed to compare the capacity, cost, and greenhouse gas (GHG) emissions of select LCNG production pathways. The study analyzes the use of fuel from these pathways in light-, medium-, and heavy-duty vehicle applications. Economic and life-cycle GHG emissions analysis suggest that landfill gas resources are an attractive and relatively abundant resource in terms of cost and GHG reduction potential, followed by waste water treatment plants and biomass with gasification and methanation. Total LCNG production potential is on the order of total natural gas demand anticipated in a success scenario for future natural gas vehicle adoption by 2035 across light-, medium-, and heavy-duty vehicle markets (110 trillion Btu/year).
