Exploring Decarbonization Pathways for USA Passenger and Freight Mobility
10/30/2023
Passenger and freight travel account for 28% of U.S. greenhouse gas (GHG) emissions today. This report explores pathways to reduce transportation emissions under bounding assumptions on future travel behavior, technology advancement, and policies. Results show diverse routes to 80% or more well-to-wheel GHG reductions by 2050. Rapid adoption of zero-emission vehicles coupled with a clean electric grid is essential for deep decarbonization. Increased sustainable biofuel usage is also essential for decarbonizing aviation and to support legacy vehicles during the transition. Managing travel demand growth can ease this transition by reducing the need for clean electricity and sustainable fuels.

Clean Cities Alternative Fuel Price Report, July 2023
9/21/2023
The Clean Cities Alternative Fuel Price Report for July 2023 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 July 1, 2023 and July 15, 2023, 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 10 cents from $3.69 to $3.59; diesel decreased 37 cents from $4.25 to $3.88; CNG decreased 13 cents from $2.99 to $2.86; ethanol (E85) decreased 3 cents from $2.98 to $2.95; propane decreased 38 cents from $3.63 to $3.25; and biodiesel (B20) decreased 25 cents from $4.02 to $3.77.
According to Table 3, CNG is 73 cents less than gasoline on an energy-equivalent basis and E85 is 25 cents more than gasoline on an energy-equivalent basis.

Recommendations for Minimum Required Error Codes for Electric Vehicle Charging Infrastructure
9/13/2023
This report proposes a set of Minimum Required Error Codes (MRECs) for electric vehicle (EV) chargers and recommends that the industry implement these uniformly across the North American EV charging ecosystem to streamline error reporting, interpretability, and diagnostics. The purpose of this document is to simplify the troubleshooting process and increase charging reliability for all EV users. This report serves as a recommendation for industry stakeholders, encouraging a unified methodology to define and classify a minimum required set of error codes.
Fast Charging Infrastructure for Electrifying Road Trips to and from National Parks in the Western United States
9/12/2023
National parks in the Western United States draw over 80 million visitors every year, and most visitors rely on personal cars for their road trips (or long-distance travels). Travel to national parks represents distinct travel demand, as they are typically located in remote areas necessitating long-distance trips. This study investigates the quantity and locations of on-route fast charging infrastructure needed by 2030 to enable seamless travel to/from national parks using electric vehicles in seven target states in the region, employing unprecedented high-resolution spatial and temporal analysis.

Electric Vehicle Managed Charging: Estimating the Potential Bulk Power System Value
8/1/2023
Numerous studies have estimated the potential value of EV managed charging. In this study, NREL leveraged more detailed modeling of EV adoption, use, charging, and bulk power system operations to understand the potential value. Unique to this study, NREL modeled different charging flexibility types and dispatch mechanisms—as well as participation rates among drivers in having their EV charging managed—starting from vehicle-specific descriptions of charging flexibility.
