Transitioning to lower-sulfur diesel has impacted production costs
In 2006, the U.S. began to transition to ultra-low-sulfur diesel (ULSD) to reduce the production of harmful compounds like sulfur dioxide during fuel combustion. This transition required refineries to invest billions of dollars in new equipment, which increased the cost of producing diesel. The cost of removing sulfur from diesel also led to a slight decrease in the energy content of the fuel, impacting its fuel economy.
Prior to the U.S. transition to ULSD, Europe had already begun tightening sulfur specifications in the 1990s. For example, Sweden introduced diesel fuel with a sulfur content of 50 parts per million (ppm) in 1990, and by 1992, production started on diesel fuel with 2-5 ppm of sulfur. In 2003, Sweden introduced EcoPar, a diesel fuel with "zero" sulfur content and very low aromatic volume. Similarly, in 2006, California proposed reducing the maximum sulfur content in diesel fuel from 500 ppm to 15 ppm, which was expected to add two to four cents per gallon to the production cost of diesel fuel.
The transition to lower-sulfur diesel has impacted production costs in several ways. Firstly, the process of removing sulfur from diesel is technically challenging and expensive. The equipment required to remove sulfur from diesel fuel is costly, and the ongoing operating costs of this equipment further increase production costs. Additionally, the removal of sulfur results in the loss of naturally occurring lubricity agents, requiring the addition of lubricity enhancers to meet fuel standards.
The transition to lower-sulfur diesel has also impacted the relative prices of different grades of crude oil. As refiners sought to reduce the sulfur content of diesel fuel, the demand for low-sulfur ("sweet") crudes increased, driving up their price relative to high-sulfur ("sour") crudes. This dynamic further contributed to the overall increase in production costs for diesel fuel.
Overall, the transition to lower-sulfur diesel has had a significant impact on production costs, leading to higher prices for diesel fuel relative to gasoline. The additional capital and operating expenses associated with meeting stricter sulfur regulations have made diesel a more expensive fuel option.

Excise tax for on-highway diesel is higher than on gasoline
The federal excise tax for on-highway diesel fuel is higher than that for gasoline. This is one of the reasons why diesel fuel prices have been higher than regular gasoline prices in recent years. The federal excise tax for on-highway diesel fuel is 24.3 cents per gallon, which is 6 cents per gallon higher than the federal excise tax on gasoline.
The higher excise tax on diesel fuel is due to the fact that diesel fuel is used more by commercial trucks and other heavy machinery such as those used in farming and construction. Diesel engines are often used in big rigs that travel on highways, while gasoline engines are typically used by daily drivers in city areas. The higher tax reflects the greater fuel consumption by diesel vehicles.
In addition to the excise tax, the transition to lower-sulfur diesel fuels has also impacted diesel fuel production and distribution costs. In the years leading up to 2006, refineries had to invest billions of dollars in equipment to remove sulfur from diesel fuel to meet the new ultra-low-sulfur diesel (ULSD) standards. These additional capital and operating costs contributed to the higher price of diesel fuel.
The demand for diesel fuel has also been relatively high, especially in Europe, China, India, and the United States. This high demand, coupled with the limited supply of diesel as a "tight molecule", has driven up the price of diesel fuel. The recent disruption in U.S. diesel supplies due to the cessation of Russian oil imports has also contributed to the price differential between diesel and gasoline.

Diesel has more energy per gallon than gasoline
Diesel fuel has a higher energy density than gasoline, meaning it contains more energy per gallon. This makes it a preferred fuel for trucks as it provides more miles per gallon. It is also the best jet fuel due to its high energy content and efficiency.
The higher energy content of diesel is one of the reasons why it is more expensive than gasoline. Diesel has a higher energy content per unit of weight and volume (barrel) due to its higher BTU (British Thermal Unit) value. This means that less space and energy are required to transport diesel, making it more valuable and commanding a higher price.
The transition to ultra-low-sulfur diesel (ULSD) in the United States also contributed to the increased cost of diesel fuel. The combustion of high-sulfur fuels leads to the production of harmful compounds like sulfur dioxide, which can cause respiratory issues and contribute to acid rain. To meet the new ULSD standards, refineries had to invest significant capital in equipment to remove sulfur, resulting in higher production costs for diesel.
Additionally, the demand for diesel fuel has been relatively high, especially in regions like Europe, China, India, and the United States. This increased demand has also contributed to the higher price of diesel fuel.
It's worth noting that while diesel fuel has a higher energy content per gallon, the overall yield of gasoline from a barrel of crude oil is higher than that of diesel. This means that refineries produce more gasoline than diesel from the same amount of crude oil, which can impact the supply and, consequently, the pricing of these fuels.

Russia's invasion of Ukraine disrupted US diesel supplies
The Russian invasion of Ukraine has had a profound impact on global energy markets, causing a significant shift in the flow of natural gas, crude oil, and refined products. This has resulted in a disruption to US diesel supplies, with far-reaching consequences.
Prior to the war, Russia was a significant supplier of energy to Europe, including refined oil products such as diesel. With the invasion, the dynamic changed drastically. In response to Europe's support for sanctions, Russian President Vladimir Putin weaponized energy supplies, disrupting the global energy network. This led to a search for new suppliers beyond traditional sources in the Middle East.
The US, which had imported Russian oil, primarily in the form of partially finished products used to produce diesel in US refineries, was particularly affected. President Biden's subsequent decision to halt Russian oil imports contributed to a substantial disruption in the US refining sector. While the US didn't rely heavily on Russian crude oil, the imports of diesel and heavy oils were crucial to the country's diesel supplies.
The impact of these decisions was felt across the US, with gas stations running dry and prices skyrocketing. The refinery disruption hit diesel production hard, especially considering the two high-demand seasons for diesel in spring and fall. The situation was further exacerbated by the increased demand for diesel in Europe, China, India, and the United States, as well as the transition to less polluting, lower-sulfur diesel fuels, which affected production and distribution costs.
The war in Ukraine has undoubtedly played a pivotal role in disrupting US diesel supplies, triggering a chain reaction of events that have had a lasting impact on energy markets and diesel prices. The gradual return to normalcy is underway, but the events of the past year have highlighted the fragility of energy security and the interconnectedness of global energy networks.
