Hydrogen Fuel Cell Electric Vehicles

1/9/2025

A hydrogen fuel cell electric vehicle (FCEV) is two to three times more efficient than a comparable vehicle powered by an internal combustion engine running on gasoline. Because of their efficient operation, FCEVs can travel long distances with less fueling. A FCEV also produces clean tailpipe exhaust, emitting only water vapor and warm air. FCEVs have driving ranges of more than 300 miles per tank of hydrogen. Drivers can fuel their FCEVs in less than five minutes at a dispenser that looks and feels similar to gasoline dispensers except for the high-pressure gaseous connection. In addition, FCEVs are propelled by an electric motor, so they are very quiet, have very few moving parts and fewer fluids to change, and have minimal maintenance requirements overall.

Answers to Common Questions About Electric Vehicles

12/31/2024

Electric vehicles (EVs), also called all-electric or battery electric vehicles (BEVs), offer many benefits. They operate smoothly and quietly and have responsive acceleration, zero tailpipe emissions, and low costs for maintenance and fueling. Plug-in hybrid electric vehicles (PHEVs) offer many of the same benefits but can run on both electricity and gasoline, allowing for extended range for long trips without the need to recharge. As a consumer, you may be drawn to these features, but you may also have some questions that make you cautious about purchasing an EV. This fact sheet, provides information that will help you make an informed decision about EVs.

Sustainable Aviation Fuel Blending and Logistics

11/25/2024

Decarbonizing aviation requires a multipronged approach in both alternative fuel use and efficiency to meet emissions reductions and sustainability requirements and goals. In 2022, aviation accounted for 2.1% of human-induced carbon dioxide (CO2 ) emissions and 12% of transportation CO2 emissions (ATAG 2024). About 80% of aviation emissions are from flights longer than about 930 miles (ATAG 2024). Aviation was also responsible for 9% of domestic transportation greenhouse gas emissions in 2022 (EPA 2022). The United States has a significant commercial aviation sector accounting for nearly 28% of global jet fuel use (IATA 2024b, EIA 2024g).

Electric Medium- and Heavy-Duty Vehicle Charging Infrastructure Attributes and Development

11/1/2024

This report focuses on charging and infrastructure requirements for medium- and heavy-duty (MD/HD) vehicles in addition to potential synergies with light-duty vehicle (LDV) infrastructure. As electric vehicle (EV) deployments are more mature in the LDV sectors than MD/HD, quantitative inputs for modeling requirements for MD/HD are also still in development. That said, this report presents more qualitative analyses than quantitative. Specifically, the report covers vehicle classes, populations, and types of charging; MD/HD dwelling at depots vs. residences; and en-route MD/HD charging infrastructure, including electrical and physical space needs, connectors, and payment, pricing, and grid considerations. The report also provides considerations for appropriate fleet targeting for vehicle electrification.

SAF Policy Scorecard: Evaluating State-Level Sustainable Aviation Fuel Policies in the United States

11/1/2024

As several states across the U.S. have begun to adopt or consider policies to expand sustainable aviation fuel (SAF) development, this paper compares key provisions for state-level policies, analyzes the state support available to fund each policy initiative, and assesses the potential of each policy to support federal goals of decarbonization and sustainability. This report also highlights three critical shortcomings in the current U.S. SAF policy landscape: 1) state support for some SAF pathways may not increase overall low-carbon fuel supply; 2) short-term or short-lived policies may impede long-term SAF investment; and 3) existing SAF policy frameworks incentivize the use of SAF without penalizing aviation emissions, violating the “polluter pays” principle.
