Sustainable Aviation Fuel (SAF) State-of-Industry Report: Hydroprocessed Esters and Fatty Acids Pathway
7/1/2024
This technical report from the National Renewable Energy Laboratory (NREL) details the sustainable aviation fuel (SAF) production process, with a particular focus on the hydroprocessed esters and fatty acids (HEFA) pathway, which is currently the only commercially deployed SAF production pathway to produce a significant volume of fuel. The report outlines and evaluates the HEFA supply chain and identifies obstacles that could hinder future commercial production. While specific to SAF, this report may offer information relevant to the production of other liquid transportation fuels due to the more widely applicable nature of producing hydrocarbon fuels.

Powering Progress: Advancing Transportation Electrification in Rural Southeastern Communities
7/1/2024
This report follows up on a 2022 Electrification Coalition report, Electric Vehicles (EVs) in Rural Communities, in addressing common roadblocks to transportation electrification in the rural, Southeast U.S. by providing case study examples of how communities have overcome these challenges. As rural communities are particularly susceptible to the effects of oil-dominated transportation systems, examples of successful electrification pathways are critical to wide-reaching EV deployment.
Pollutant Emissions from Light-Duty Vehicles Across North America: A Comparative Analysis
7/1/2024
Drawing on remote sensing data from the Real Urban Emissions Initiatives as well as the Clean Air Strategic Alliance’s ROVER III campaign, this report provides up-to-date vehicle emissions data for several pollutants (hydrocarbons [HC], carbon monoxide [CO], and nitrogen oxide [NO]) in Colorado, Virginia, Mexico City, and Alberta, Canada. The report compares data by vehicle category (i.e., light-duty vehicles, personal vehicles, and taxis), vehicle manufacturer, vehicle acceleration, and more. By providing emissions measurement information, such as the ambient temperature and atmospheric pressure during which measurements were taken, the report offers insights into how different climatic conditions may affect vehicle emissions.

Sustainable Aviation Fuel (SAF) State-of-Industry Report: State of SAF Production Process
7/1/2024
Because of their compatibility with existing fuel infrastructure and vehicle technologies, biofuels will be a critical component of decarbonizing hard-to-abate sectors in the U.S. Sustainable aviation fuel (SAF) will similarly be a changemaker in the aviation industry. This study examines the various SAF production pathways, provides an overview of the current state of the industry, and addresses challenges and hurdles facing the industry in order to proactively mitigate their impact.

Customer-Focused Key Performance Indicators for Electric Vehicle Charging
6/18/2024
Electric vehicles (EVs) are a rapidly growing portion of the light-duty vehicle market, but their sustained success is closely linked to the reliability and ease-of-use of public EV chargers. To mitigate issues such as long wait times, difficulties starting charging sessions, and slow charging speeds, this report recommends two sets of numerically defined key performance indicators (KPIs) based on customer pain points that will help streamline the transition to clean vehicles. These KPIs target the following: charger access, starting and completing a charge, and charger-related safety and comfort.

Physical Safety and Security at Electric Vehicle Charging Sites
6/1/2024
As electric vehicle (EV) demand grows, so does the need for more robust EV charger safety and security. EV charger host sites must work to uplift driver and passenger confidence by incorporating design elements that promote greater safety and security. This help sheet outlines various best practices for public EV chargers. While the help sheet indicates the higher monetary costs attributed to greater safety and security measures, it also clarifies the greater repeat customers rates that result from these improvements.
Best Practices for Gig Drivers' Transition to Electric Vehicles
6/1/2024
Despite using a greater proportion of hybrid vehicles, transportation network company (TNC) drivers, or gig drivers, produce more greenhouse gas emissions than average drivers because of “deadheading,” or trips taken enroute from one passenger’s drop-off to another’s pickup. Further, gig drivers’ wages are low, often barely crossing the poverty line for a family of four. This report addresses the equity barriers to decarbonizing the gig transportation economy and provides programmatic recommendations to assist gig drivers transition to electric vehicles.

Navigating Options for Transportation Electrification and Solar Charging: Steps and Lessons Learned in Montana Communities
6/1/2024
Drawing on analysis and outreach in three Montana communities (Missoula, Bozeman, and Whitefish), this report provides guidance and best practices for other towns and cities across the country on how to effectively implement electric vehicle (EV) transportation options into their communities. The report incorporates logistical considerations—vehicle types, chargers, electricity generation—and useful strategies—effective stakeholder engagement, coordinating EV charging and renewable energy generation, and more—to cover the technological, economic, and environmental aspects of the transition to EVs.

Grid-Constrained Electric Vehicle Fast Charging Sites: Battery-Buffered Options
6/1/2024
America’s electric vehicle (EV) charging network is growing quickly, but many rural regions across the country experience electrical grid restraints that complicate the EV charger build-out. Government agencies must still devise strategies for deploying chargers in these locations where electrical grid capacity is more limited. This technical assistance case study provides guidance on battery-buffered options for EV charging sites with limited grid capacity, including infrastructure solutions, project economics, energy specification methods, technical considerations, and other relevant strategies.
Embedding Equity into Community EV Readiness Planning
6/1/2024
New electric vehicle (EV) infrastructure presents an opportunity to imbed greater equity into surrounding communities. Doing so ensures that all community members are heard during the nationwide clean transition, and also streamlines the process of securing funding from federal offices that prioritize equity-based initiatives such as Justice40. This help sheet examines pathways to more effectively embed equity considerations into EV charger development, including strategies for community outreach, zoning, needs assessments, receiving funding, and more.
Best Practices for EV Carsharing Programs
6/1/2024
Carsharing programs are common throughout the U.S., but few so far have focused on electric vehicles (EVs). Over the past six years, Forth Mobility has developed and trialed several EV carshare programs to identify and better understand the best practices and roadblocks to implementing these programs in underserved areas, such as in low-income and rural communities. This paper shares lessons learned by analyzing the following subject areas: revenue planning; site host, technology platform, and vehicle type selection; educational outreach; marketing strategies; and community organization partnerships.

Solar Power + Electric Vehicle Charging: Capturing Synergies in Minnesota
6/1/2024
A suite of aggressive climate action legislation, including a series of solar development commitments, has contributed to Minnesota reducing the carbon intensity of its power sector by 29% over 2013 levels. However, the carbon footprint of each sector has not dropped equally. In 2018, the transportation sector overtook power generation as the leading emissions producer statewide. The same focus on solar energy—combined with electric vehicle (EV) use—offers a vital opportunity for Minnesota to decrease transportation emissions. The analysis in this report examines the underdeveloped synthesis between solar production and EV charging, presenting seven key findings paired with relevant recommendations to transform the market and decrease transportation-based emissions.
