Fossil fuels are used for transportation in the form of petroleum products, including gasoline, diesel, jet fuel, and propane. In 2023, petroleum products accounted for about 89% of the total US transportation sector energy use. Gasoline is the dominant transportation fuel in the United States, followed by distillate fuels (mostly diesel) and jet fuel. However, the use of fossil fuels in transportation is a major source of emissions, with the transport sector accounting for more than a third of CO2 emissions from end-use sectors. To reduce emissions, there is a growing emphasis on adopting electric vehicles and renewable fuels, with the goal of transitioning away from fossil fuels.

Gasoline and diesel fuel
Gasoline is the dominant transportation fuel in the United States, accounting for 52% of total energy consumption by the US transportation sector in 2022. It is used in cars, motorcycles, light trucks, boats, and many types of airplanes. Most of the motor gasoline sold in the US contains up to 10% ethanol by volume.
Gasoline is made from crude oil and natural gas processing. It is a petroleum product, and the US imports two-thirds of all the petroleum it uses. In 2021, petroleum products accounted for about 90% of the total US transportation sector energy use.
Biofuels, including ethanol and biomass-based diesel, are often added to gasoline. In 2022, biofuels consumption accounted for about 6% of total US transportation sector energy consumption.
Diesel fuel, also a petroleum product, is another commonly used fossil fuel for transportation. It is used in trucks, buses, trains, boats, ships, and construction, farming, and military equipment. Diesel fuel offers a wide range of performance, efficiency, and safety features. Most diesel fuel used in the US is refined from crude oil, although the use of biodiesel and renewable diesel is increasing.

Jet fuel
Jet A and Jet A-1 are types of jet fuel used by commercial airlines, while JP (Jet Propellant) is used by the military in the United States and other NATO nations. JP is a complex mixture of primarily aliphatic hydrocarbons, derived from crude oil and/or kerosene, with various additives to enhance performance and prevent issues like fuel icing. The most recent JP variant, JP-8, consists of 9 to 17 different hydrocarbons and thousands of isomers.
The use of jet fuel contributes significantly to global energy consumption and carbon dioxide emissions. Aviation accounts for about 2% of all carbon dioxide emissions and 12% of transportation-related emissions worldwide. To address this, the international aviation industry has set a goal of reaching net-zero carbon emissions by 2050. Efforts to reduce emissions include the development of Sustainable Aviation Fuel (SAF), which can be blended with conventional jet fuel and used in existing aircraft and infrastructure. SAF consumption is increasing, with approximately 24.5 million gallons consumed in 2023.
Biofuels, such as biomass-based renewable hydrocarbon biofuels, are also being explored as an alternative to jet fuel. These biofuels can be used to produce green jet fuel, which is compatible with existing combustion engines and infrastructure. The use of biofuels and SAF is expected to play a crucial role in reducing the environmental impact of aviation and meeting sustainability goals.

Biofuels
Ethanol is an alcohol that can be blended with gasoline to increase octane levels and reduce carbon monoxide and smog-causing emissions. The most common blend is E10 (10% ethanol, 90% gasoline), which is approved for use in most conventional gasoline-powered vehicles. Some vehicles, called flexible fuel vehicles, can run on blends with much higher ethanol content, such as E85. In the United States, roughly 97% of gasoline contains some ethanol.
Biodiesel, on the other hand, is produced by combining alcohol with vegetable oil, animal fat, or recycled cooking grease. It is a cleaner-burning replacement for petroleum-based diesel fuel and can be used in compression-ignition (diesel) engines. Biodiesel can be blended with petroleum diesel in any proportion, with B20 (20% biodiesel, 80% petroleum diesel) being the most common blend.
To further promote the use of biofuels, governments have implemented various programs and regulations. For example, the US Renewable Fuel Standard (RFS) and California's Low Carbon Fuel Standard (LCFS) define the types of biofuels and processes by which they can be produced to qualify for use under these programs. Additionally, the United States Inflation Reduction Act (IRA) provides an estimated USD 9.4 billion in support for biofuel production and investment until 2031. With continued advancements in technology and increasing demand for renewable energy sources, the use of biofuels in transportation is expected to grow in the coming years.

Electric vehicles
Today, concerns about the environmental impact of emissions from internal combustion engines have led to a resurgence in the popularity of EVs. The private sector and government agencies are investing significant resources to promote the adoption of EVs in the United States. There are two main types of EVs available: battery electric vehicles (BEVs) and plug-in hybrid electric vehicles (PHEVs). BEVs use stored electrical energy in a battery pack to fully operate and move the vehicle. PHEVs, on the other hand, can use either an electric motor powered by an onboard battery pack or an internal combustion engine that uses fuel stored in onboard tanks.
EVs offer several benefits over conventional internal combustion engine vehicles. They have lower fuel costs due to the high efficiency of electric-drive components and technologies such as regenerative braking. EVs also have lower maintenance needs, improved performance, and reduced environmental impact. In fact, BEVs are considered zero-tailpipe-emission vehicles because they do not directly emit any criteria pollutants or greenhouse gases during operation. Additionally, EVs strengthen national energy security by reducing dependence on fossil fuels and increasing resilience to fuel supply disruptions.
Despite these advantages, there are some challenges associated with EVs. The initial purchase price of EVs can be significantly higher than that of conventional vehicles. However, these costs can be offset over time by fuel cost savings, federal tax credits, and state and utility incentives. Additionally, the batteries in EVs have a limited lifespan and will eventually need to be replaced. The range of BEVs can also be impacted by weather conditions, with extreme temperatures reducing their efficiency and travel range.
To address these challenges, the U.S. government has set ambitious goals for the adoption of zero-emissions vehicles. By 2030, the government aims for half of all new vehicles sold in the U.S. to be zero-emissions, and significant funding has been allocated for the development of EV charging infrastructure. This includes the Bipartisan Infrastructure Law, which provides $7.5 billion for EV charging stations and makes EV charging infrastructure eligible for additional federal funding programs.

Hydrogen fuel
Hydrogen can be used as a low-emission fuel in internal combustion engines (ICEs), providing a lower-cost pathway for fleets to adopt hydrogen technologies. Hydrogen fuel cells can also be used in combination with batteries to power vehicles. Fuel cells have been shown to operate reliably, refuel quickly, and extend the range of the vehicle over battery-powered alternatives. They are also more suitable for extreme temperatures. Hydrogen fuel cells are being used in buses, heavy-duty trucks, and forklifts, as well as in some warehouse material handling devices.
Hydrogen is produced by steam reforming of natural gas, although biomass, coal, and even plant materials can also be used as feedstocks. The process of producing hydrogen fuel can be energy-intensive and result in carbon dioxide and methane emissions. However, when hydrogen is generated from solar or wind electrolysis, carbon dioxide emissions are eliminated.
The growth in hydrogen demand will require the expansion of the supply chain and the development of new technologies, such as chemical carriers to transport hydrogen at high density. Hydrogen fueling infrastructure is currently available commercially, and several U.S. companies deliver bulk hydrogen. However, wide-scale growth in demand will require further research and development, as well as new deployments.
