What You'll Learn
Jet fuel is cheaper due to economies of scale and demand
Jet fuel is cheaper than diesel due to a combination of factors, including economies of scale and demand. Firstly, jet fuel is produced and consumed in much larger quantities than diesel. The high volume of jet fuel production allows refineries to achieve economies of scale, spreading their fixed costs across a larger number of units, thereby reducing the average cost per unit. This economic principle contributes to the overall lower price of jet fuel compared to diesel.
Additionally, the demand for jet fuel from airlines further drives down prices. Airlines purchase significant amounts of fuel, and their large-scale buying power enables them to negotiate favourable contracts with fuel suppliers. The competition among suppliers to secure these contracts also helps to keep prices competitive. The higher the demand, the more suppliers can justify producing jet fuel, which further contributes to the economies of scale and drives prices down.
The specific composition and characteristics of jet fuel also play a role in its pricing. Jet fuel, particularly Jet-A type, has a simpler refining process compared to other fuels. It is also easier to transport, as it does not contain lead and can be piped directly to aircraft. This simplicity in refining and transportation contributes to cost savings, making jet fuel more affordable than diesel.
Furthermore, jet fuel and diesel have different taxation structures. In certain regions, jet fuel attracts lower taxes compared to diesel. The combination of central and state taxes, including value-added tax (VAT), results in a lower overall tax burden on jet fuel. This tax structure further contributes to jet fuel being cheaper than diesel, especially in specific geographical contexts.
While jet fuel is generally cheaper due to these factors, it is important to note that the specific prices of jet fuel and diesel can vary over time and across different regions. Market dynamics, supply and demand fluctuations, and local regulations can all influence the pricing of these fuels. However, the underlying factors of economies of scale and demand remain key contributors to the overall lower cost of jet fuel.

Jet fuel is easier to refine and transport
Jet fuel and diesel fuel have a lot in common. Historically, jet fuel and diesel were quite similar in extraction, production, composition, and application. However, jet fuel and diesel fuel have diverged over time in terms of composition, application, and broader use.
Jet fuel is also cheaper to produce when compared to other types of jet fuel. Jet A-1, for instance, requires the use of an anti-static additive in its composition, while Jet A does not. Jet A is the most commonly used jet fuel, though it is only used in North America with a few exceptions.
The low popularity of diesel aircraft engines is mainly due to the low power-to-mass ratio of diesel engines. Diesel engines are usually heavy, and as they produce more power, they also need to become heavier. This is a significant disadvantage for aircraft.
Overall, jet fuel is easier to refine and transport than diesel due to its simpler refining process, ease of transportation, and higher production volume.

Jet fuel and diesel have different compositions and lubricity
Despite their seemingly disparate names, jet fuel and diesel fuel share more similarities than one might assume. Historically, jet fuel and diesel were comparable in terms of extraction, production, composition, and application. However, over time, they diverged, particularly in terms of composition, extraction techniques, and broader use.
The main distinction between diesel and jet fuels lies in their composition. Jet fuel, particularly Jet-A, is characterised as being relatively dry compared to diesel fuel. While jet fuel is considered a high-sulfur fuel, its lubricity is suitable for gas-turbine engines. In contrast, diesel fuel requires the addition of lubricity additives to ensure the longevity and proper functioning of the injector system in diesel engines. The absence of these additives can lead to increased wear and tear on crucial components, such as fuel injectors and pumps, resulting in reduced engine performance.
The different compositions of jet fuel and diesel fuel are influenced by their intended applications. Jet fuel, also known as aviation turbine fuel (ATF), is specifically designed to power gas-turbine engines in aircraft, including commercial airliners, military jets, helicopters, and more. Its high energy density provides the necessary power for takeoff and long-distance flights. Additionally, jet fuel exhibits excellent cold-weather performance due to additives and individual properties that prevent freezing at high altitudes.
On the other hand, diesel is a versatile petroleum-based fuel used in internal combustion engines. It offers greater torque and energy per litre, making it ideal for ground-based power and endurance in various industries, including construction, agriculture, transportation, and marine applications. Diesel engines are typically heavier, and their power-to-mass ratio is lower than that of jet fuel engines, making them less suitable for aircraft use.
The differences in composition and lubricity between jet fuel and diesel fuel are significant and impact their respective performance and suitability for specific types of engines. While jet fuel is dry and high in sulfur content, it functions well in gas-turbine engines. In contrast, diesel fuel relies on additives to maintain the lubricity necessary for the smooth operation of diesel engines.

Jet fuel is safer with a higher flash point
Jet fuel is a type of aviation fuel designed for use in aircraft powered by gas-turbine engines. It is typically straw-colored or colorless. The two most common types of jet fuel are Jet A and Jet A-1, which are produced according to international standards. Jet B is another type of jet fuel used for its superior performance in cold weather. Jet fuel is a mixture of hydrocarbons, and its exact composition varies based on its petroleum source. Thus, it is defined as a performance specification rather than a chemical compound.
Jet fuel and diesel fuel have more in common than one might think. Historically, the two fuels were quite similar in extraction, production, and composition. However, the main difference between them lies in their composition, and they have diverged over time in terms of application and broader use. Jet fuel is considered a high-sulfur fuel with relatively low lubricity compared to diesel fuel. Diesel engines require lubricity additives to ensure the injector system works correctly over an extended period.
The flash point of a material is the lowest liquid temperature at which it gives off enough vapors to form an ignitable vapor/air mixture under certain standardized conditions. Flash points are used to distinguish between flammable and combustible fuels and to characterize their fire hazards. Fuels with a flash point below 37.8°C (100.0°F) are considered flammable, while those with a higher flash point are deemed combustible. The flash point is not the same as the autoignition temperature, which is the temperature at which spontaneous ignition occurs. The fire point is also higher than the flash point, as the latter may not produce enough vapor to sustain combustion.
Jet A and Jet A-1 fuels have a flash point higher than 38°C (100°F) and an autoignition temperature of 210°C (410°F). In contrast, the flash point of diesel fuel ranges from 52°C to 96°C (126°F to 205°F). Thus, jet fuel has a higher flash point than diesel, making it safer to use. A higher flash point means that jet fuel requires a higher temperature to ignite, reducing the risk of accidental ignition. This is particularly important for aircraft safety, as jet fuel is used to power gas-turbine engines in commercial aviation.
In summary, jet fuel has a higher flash point than diesel fuel, contributing to its safety characteristics. The higher flash point of jet fuel reduces the risk of accidental ignition, making it suitable for use in aircraft engines.

Diesel is heavier and less powerful than jet fuel
Although jet fuel and diesel fuel have a lot in common, there are some key differences between the two. One of the main differences is their composition, which has diverged over time, affecting their extraction, composition, and broader use.
Diesel engines have a much higher compression ratio than gasoline engines, requiring more electrical power to start, which usually means a higher-capacity battery. This adds weight, which is a significant disadvantage for aircraft. Diesel engines also need lubricity additives to work correctly over a long period, whereas jet fuel is considered to have acceptable lubricity for gas-turbine engines.
The weight of diesel engines is a crucial factor in their lack of popularity for aircraft use. As diesel engines produce more power, they also need to be heavier. This weight has a direct impact on the payload capacity of aircraft, reducing it considerably when compared to the same aircraft using traditional gasoline piston engines.
The specific weight of diesel fuel also impacts the payload of an aircraft. For example, 100 liters of diesel fuel weighs 19 kg more than the same volume of gasoline, which directly affects the passenger payload of an aircraft.
Overall, the heavier weight and lower power-to-mass ratio of diesel engines and fuel make them less powerful and less suitable for aircraft use when compared to jet fuel and engines.
