Clean Cities Alternative Fuel Price Report, April 2022

6/28/2022

The Clean Cities Alternative Fuel Price Report for April 2022 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, 2022 and April 15, 2022, 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 85 cents from $3.28 to $4.13; diesel increased by $1.44 from $3.62 to $5.06; CNG increased 10 cents from $2.49 to $2.59; ethanol (E85) increased 57 cents from $2.97 to $3.54; propane increased 11 cents from $3.42 to $3.53; and biodiesel (B20) increased by $1.20 from $3.42 to $4.62.

According to Table 3, CNG is $1.54 less than gasoline on an energy-equivalent basis and E85 is 47 cents more than gasoline on an energy-equivalent basis.

Electric Vehicle Supply Equipment Standards Technology Review

2/1/2022

Zero-emission transportation is critical to achieving California’s air quality and climate goals. To support the adoption and use of zero-emission vehicles, the California Air Resources Board (CARB) adopted the Electric Vehicle Supply Equipment (EVSE) Standards Regulation in 2019 to reduce barriers to accessing public charging stations. The EVSE Standards Regulation establishes minimum requirements for payment methods an EVSE must allow, facilitates roaming agreements between electric vehicle service providers, creates a more complete database of location and pricing information for consumer use, and ensures clarity in the cost of a charging session. To assess barriers drivers may face and understand whether the requirements of the Regulation, particularly the requirement that EVSE must accept both chip payment cards and contactless, “tap” cards, CARB staff conducted a Technology Review. The Technology Review included an evaluation of the availability and use of different payment methods and a survey of drivers’ experiences accessing public charging stations. This report presents the findings and recommendations from that work.

Ethanol Production in the United States: The Roles of Policy, Price, and Demand

11/26/2021

Assessments of the impact of the U.S. renewable fuel standard (RFS) should inform consideration of future biofuels policy. Conventional wisdom suggests the RFS played a major role in stimulating the ten-fold expansion in ethanol production and consumption in the United States from 2002 to 2019, but evidence increasingly suggests the RFS may have had a smaller effect than previously assumed. Price competitiveness, federal and state policies such as reformulated gasoline requirements, and octane content in ethanol also affect market attractiveness. This study explores the roles of policy and economic factors by comparing historical data with results from scenarios simulated in a system dynamics model.

Levelized Cost of Charging Electric Vehicles in the United States

7/15/2020

The cost to charge an electric vehicle (EV) varies depending on the price of electricity at different charging sites (home, workplace, or public), vehicle use, region, and time of day, and for different charging power levels and equipment and installation costs. This paper provides a detailed assessment of the 2019 levelized cost of light-duty PEV charging in the United States, considering the purchase and installation costs of charging equipment and electricity prices from real-world utility tariffs.
