Clean Cities Alternative Fuel Price Report, October 2019
11/18/2019
The Clean Cities Alternative Fuel Price Report for October 2019 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, 2019 and October 15, 2019, 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 decreased 8 cents from $2.76 to $2.68; diesel increased 4 cents from $3.04 to $3.08; CNG decreased a cent from $2.21 to $2.20; ethanol (E85) decreased 8 cents from $2.36 to $2.28; propane decreased 7 cents from $2.83 to $2.76; and biodiesel (B20) increased 1 cent from $2.86 to $2.87.
According to Table 3, CNG is $.48 less than gasoline on an energy-equivalent basis, while E85 is $0.29 more than gasoline on an energy-equivalent basis.

Clean Cities Coalitions 2017 Activity Report
5/14/2019
The U.S. Department of Energy's (DOE's) national network of Clean Cities Coalitions advance the nation's economic, environmental, and energy security by supporting local actions to promote the use of domestic fuels within transportation. The nearly 100 Clean Cities coalitions, whose territory covers 80% of the U.S. population, bring together stakeholders in the public and private sectors to use alternative and renewable fuels, idle-reduction (IR) measures, fuel economy improvements, and new transportation technologies as they emerge. To ensure success, coalitions leverage a robust set of expert resources and tools provided by national laboratories and DOE. Each year, Clean Cities coordinators submit annual reports of their activities and accomplishments for the previous calendar year. Data and information are submitted via an online tool 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; use of alternative fuel vehicles (AFVs), plug-in electric vehicles (PEVs), and hybrid electric vehicles (HEVs); IR initiatives; fuel economy improvement activities; and programs to reduce vehicle miles traveled (VMT). NREL analyzes the submitted data to determine how broadly energy use in the U.S. has shifted due to coalition activities, which are summarized in this report.

Metals Analysis of Biodiesel Blends
5/1/2019
The goal of this study was to compare metals analysis methods for biodiesel blends. Thirty-five B20 samples were collected from public stations and private fleets throughout the United States. All samples were analyzed for blend content and critical properties under the ASTM D7467 specification. Although not part of the specification, metals content, specifically Na, K, Ca, Mg, and P, is becoming an increasingly larger concern for industry. This study compared the metals content of the B20 samples using inductively coupled plasma atomic emission spectroscopy (ICP-AES), inductively coupled plasma mass spectrometry (ICP-MS), and microwave plasma atomic emission spectroscopy (MP-AES) methods. All three techniques showed improvements over the current detection limits of 1 ppm for Na, K, Ca, and Mg, and 5 ppm for P. Some differences were found between methods, but agreement was generally acceptable at the very low levels present in these samples. The MP-AES technique showed good promise for future development for this type of analysis.

Model Year 2020 Fuel Economy Guide: EPA Fuel Economy Estimates
12/19/2018
The Fuel Economy Guide is published by the U.S. Department of Energy as an aid to consumers considering the purchase of a new vehicle. The Guide lists estimates of miles per gallon (mpg) for each vehicle available for the new model year. These estimates are provided by the U.S. Environmental Protection Agency in compliance with Federal Law. By using this Guide, consumers can estimate the average yearly fuel cost for any vehicle. The Guide is intended to help consumers compare the fuel economy of similarly sized cars, light duty trucks and special purpose vehicles.

Ethanol Basics
9/11/2018
Ethanol is a widely used, domestically produced renewable fuel made from corn and other plant materials. Ethanol can be blended with gasoline in different amounts. In fact, more than 98% of gasoline sold in the United States contains ethanol to oxygenate the fuel and help to reduce air pollution. Using ethanol in fuel also helps the nation increase the use of domestic alternative fuels, thereby potentially reducing reliance on imported oil. Gasoline and gasoline blendstocks can also use ethanol as an octane enhancer to increase vehicle performance.

Re-Additization of Commercial Biodiesel Blends During Long-Term Storage
8/1/2018
Commercial biodiesel blends were aged at 43 degrees C while monitoring stability. The oxidation stability -- or oxidation reserve expressed as Rancimat induction period (IP) -- gradually decreased from its initial value. At a predetermined IP threshold, an antioxidant was used to restore IP to the ASTM D7467 specification minimum of 6 h, referred to as re-additization. At lower IP values, the amount of antioxidant required increased significantly, and the effectiveness tended to be reduced. Once IP fell to essentially zero, the acid content increased to above the allowable limit and insoluble material was also detected. Storage life was increased relative to the as-received fuels as evidenced by longer time to produce acids. Experience in the field may vary based on storage conditions; however, these results indicate re-additization can significantly increase storage life of biodiesel blends when used with regular monitoring of IP and acid number. An assessment of the storage stability of the as-received fuels showed that the initial IP did not predict storage behavior, although fuels above the specification minimum remained stable for >12 weeks accelerated aging (1 year simulated).
