Corridor-Level Impacts of Battery-Electric Heavy-Duty Trucks and the Effects of Policy in the United States
12/18/2023
Electrifying freight trucks will be key to alleviating air pollution burdens on disadvantaged communities and mitigating climate change. The United States plans to pursue this aim by adding vehicle charging infrastructure along specific freight corridors. This study explores the coevolution of the electricity grid and freight trucking landscape using an integrated assessment framework to identify when each interstate and drayage corridor becomes advantageous to electrify from a climate and human health standpoint.

A Deep Decarbonization Framework for the United States Economy – a Sector, Sub-Sector, and End-Use Based Approach
12/8/2023
Using the recently developed Decarbonization Analysis Model, this report analyzes the estimated greenhouse gas mitigation potential for projected energy demand based on several sector-level and cross-sectoral decarbonization pathways, including electrification, low-carbon fuels, and the reduction of fugitive emissions. The report analyzes the remaining projected emissions and highlights the need for developing low-carbon and carbon-negative alternatives to mitigate the fossil-based carbon emissions resulting from the fossil-based fuels in heavy-duty transportation.

Clean Cities Alternative Fuel Price Report, October 2023
11/29/2023
The Clean Cities Alternative Fuel Price Report for October 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 October 1, 2023 and October 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 increased 13 cents from $3.59 to $3.72; diesel increased 64 cents from $3.88 to $4.52; CNG decreased 1 cent from $2.86 to $2.85; ethanol (E85) increased 10 cents from $2.95 to $3.05; propane increased 4 cents from $3.25 to $3.29; and biodiesel (B20) increased 65 cents from $3.77 to $4.42.
According to Table 3, CNG is 87 cents less than gasoline on an energy-equivalent basis and E85 is 24 cents more than gasoline on an energy-equivalent basis.

The Current State of Light-Duty Electric Vehicle Supply Equipment Costs: An Assessment of Contemporary Understanding
11/28/2023
This technical study combines a hybrid meta-analysis with a literature review to assess the current state of knowledge regarding electric vehicle supply equipment (EVSE) costs. The study presents a novel convention for analyzing EVSE costs that includes EVSE application type (commercial or residential), power level (Level 1, 2, or direct current (DC) fast charging), and type of cost measure (hardware, installation, operation, and total cost). These measures are intended to be used as a new standard to make EVSE cost assessments more accessible, and to make cost tracking more ubiquitous.

Charge Up Your Town: Best Management Practices to Ensure Your Town is EV Ready
11/1/2023
With a goal of reducing statewide greenhouse gas emissions by 80% below 2006 levels by 2050, the State of New Jersey is making a concerted effort to electrify its transportation sector, which currently produces over 40% of the state’s emissions. This paper provides a case study on how state governments can support local municipalities in successfully converting to light-duty electric vehicle (EV) fleets and installing adequate electric vehicle supply/service equipment (EVSE). As municipalities are often in charge of installing EVSE across New Jersey, local government understanding of statewide ordinances, EV charging station installation requirements, and available financial incentives is imperative towards achieving statewide emissions reduction targets. Other state and local governments can adapt this guide to meet their own parameters.
Grid Capacity – What is it, What Determines it, Does One Number Work, and How Does it Relate to Electric Vehicles?
11/1/2023
Electrical power is used in many facets of modern life and electricity demand continues to grow. The adoption of electric vehicles (EVs), migration from natural gas to electric heat pumps, and other decarbonization efforts are expected to grow this demand even further. With this increased demand, questions arise on if the power grid can handle this load and questions of “grid capacity” emerge. This report discusses common questions about what grid capacity is and how EVs impact grid capacity.

Cradle-to-Grave Lifecycle Analysis of U.S. Light-Duty Vehicle-Fuel Pathways: A Greenhouse Gas Emissions and Economic Assessment of Current (2020) and Future (2030-2035) Technologies
11/1/2023
This study provides a comprehensive life cycle analysis (LCA), or cradle-to-grave (C2G) analysis, of the cost and greenhouse gas (GHG) emissions of a variety of vehicle-fuel pathways, the levelized cost of driving (LCD) and cost of avoided GHG emissions. The C2G analysis assesses light duty midsize sedans and small sport utility vehicles (SUVs) across a variety of vehicle-fuel technology pathways, including conventional internal combustion engine vehicles (ICEVs), flexible hybrid electric vehicles (HEVs), plug-in hybrid electric vehicles (PHEVs), battery electric vehicles (BEVs) with varying vehicle ranges, and fuel cell electric vehicles (FCEVs).

Cold Weather Impacts on Electric School Buses
11/1/2023
School bus fleets considering electric school buses (ESBs) can start here to learn how cold weather impacts ESBs and considerations for optimizing bus performance when temperatures drop. ESBs are proven to operate effectively in cold weather; however, cold temperatures will impact their range and efficiency. School bus fleets can effectively manage these impacts on ESB operations by considering effective safeguards during deployment planning.
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.
