Multi-State Transportation Electrification Impact Study
3/1/2024
This study was conducted to help answer technical and deployment questions about whether the electric grid can accommodate increasing demands from transportation electrification, particularly if it can accommodate the anticipated impact of the U.S. Environmental Protection Agency rulemakings if finalized as proposed on greenhouse gas emission standards for light-, medium-, and heavy-duty on-road vehicles The study analyzes charging infrastructure and distribution grid upgrade needs for California, Illinois, New York, Oklahoma, and Pennsylvania, which are indicative of a variety of transportation demand and utility distribution infrastructure in the United States.
Simulation-Based Assessment of Energy Consumption of Alternative Powertrains in Agricultural Tractors
2/27/2024
This report developed simulation models for conventional, parallel hybrid electric, series hybrid electric, fuel cell hybrid, and battery electric powertrain technologies for agricultural tractors, analyzing the potential energy efficiency and emissions benefits as well as technical challenges for implementing the vehicles. The study showed that both the battery electric and fuel cell hybrid tractors have higher potential to reduce energy consumption and emissions, but currently have inherent technical challenges, while the parallel hybrid and series hybrid powertrain tractors have varying energy efficiency benefits depending on the tractor size and operating cycle conditions.

Clean Cities Alternative Fuel Price Report, January 2024
2/22/2024
The Clean Cities Alternative Fuel Price Report for January 2024 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, 2024 and January 15, 2024, 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 66 cents from $3.72 to $3.06; diesel decreased 58 cents from $4.52 to $3.94; CNG increased 10 cents from $2.85 to $2.95; ethanol (E85) decreased 50 cents from $3.05 to $2.55; propane increased 20 cents from $3.29 to $3.49; and biodiesel (B20) decreased 59 cents from $4.42 to $3.83.
According to Table 3, CNG is 11 cents less than gasoline on an energy-equivalent basis and E85 is 26 cents more than gasoline on an energy-equivalent basis.

Electric Vehicle Charging Infrastructure Trends from the Alternative Fueling Station Locator: Third Quarter 2023
2/1/2024
Electric vehicle (EV) charging infrastructure continues to rapidly change and grow. Using data from the U.S. Department of Energy’s Alternative Fueling Station Locator, this report provides a snapshot of the state of EV charging infrastructure in the United States in the third calendar quarter of 2023 by charging level, network, and location. Additionally, this report measures the current state of charging infrastructure compared with a federal infrastructure requirement scenario. This information is intended to help transportation planners, policymakers, researchers, infrastructure developers, and others understand the rapidly changing landscape of EV charging infrastructure. This is the fifteenth report in a series.

Community Charging: Emerging Multifamily, Curbside, and Multimodal Practices
2/1/2024
This paper discusses the emerging practices and technologies that can be used to bring electric mobility infrastructure to those without access to privately owned electric vehicle (EV) parking or privately owned EVs. Selected case studies from Colorado, California, New York, and outside of the U.S. illustrate curbside and multimodal solutions serving those who live in multifamily housing, residents without private parking, and residents who do not own cars.

Adoption of Plug-in Electric Vehicles: Local Fuel Use and Greenhouse Gas Emissions Reductions Across the U.S
2/1/2024
This report aims to fill a research gap in the local effects of the benefits of electric vehicle (EV) adoption. The report estimates the fuel cost savings and greenhouse gas (GHG) emission reductions at the state and local zip code levels, considering local fuel prices, vehicle class preferences, vehicle model years, fuel efficiencies, and driving intensities. The report found that EV adoption can result in annual savings up to $2,200. Additionally, the report found that in over 99% of U.S. zip codes, EVs result in overall savings in fuel use and GHG emissions.

National Electric Vehicle Infrastructure Formula Program (NEVI) Brief for State Public Utility Commissions (PUCs)
2/1/2024
State PUCs will play an important role in NEVI buildout as they oversee the utility investment in a new national EV charging network. This policy brief provides an explanation of the NEVI funding process and requirements for PUCs, describing potential PUC roles in the NEVI process and considerations for state PUCs as states undergo the NEVI process. The report also details how the implementation of the NEVI program may broadly impact the future technical requirements and standards for the EV charging industry and specifically for utilities.

The Future of Biofuels in the United States Transportation Sector
12/29/2023
This article analyses conversion options for biomass to fuels in the U.S. transportation sector, particularly for heavy duty transportation and aviation, based on regional carbon dioxide transportation and injection costs and current U.S. tax credits. The article found that that under current credits biofuels play a role only in some regions of the U.S., but a range of policy scenarios, including combining biofuel production with carbon-capture and storage, can lead to biofuels playing a significant role nationally.
