Standby diesel generator sets are crucial for providing reliable power during outages or in areas with unstable power supplies. As a supplier of standby diesel generator sets, I often get asked about the types of fuel these generators can use. In this blog post, I'll explore the different fuels that standby diesel generator sets can utilize, their advantages and disadvantages, and how to choose the right fuel for your specific needs.
Diesel Fuel
Diesel fuel is the most common and widely used fuel for standby diesel generator sets. It is a hydrocarbon-based fuel that is derived from crude oil through a refining process. Diesel fuel has several advantages that make it a popular choice for generator applications:
- High Energy Density: Diesel fuel has a high energy density, which means it can produce a large amount of power per unit volume. This makes diesel generators more efficient and capable of providing continuous power for extended periods.
- Reliability: Diesel engines are known for their reliability and durability. They can operate in a wide range of environmental conditions and are less prone to breakdowns compared to other types of engines.
- Availability: Diesel fuel is readily available at most gas stations and fuel suppliers, making it easy to refuel your generator when needed.
- Long Shelf Life: Diesel fuel has a relatively long shelf life, which means it can be stored for extended periods without losing its quality. This is especially important for standby generators that may not be used frequently.
However, diesel fuel also has some disadvantages:
- Emissions: Diesel engines produce higher levels of emissions compared to other types of engines, including nitrogen oxides (NOx), particulate matter (PM), and carbon monoxide (CO). These emissions can have a negative impact on the environment and human health.
- Noise: Diesel generators can be noisy, especially when operating at full load. This can be a problem in residential areas or other noise-sensitive environments.
- Cost: Diesel fuel is generally more expensive than other types of fuels, such as natural gas or propane. This can increase the operating costs of your generator over time.
Natural Gas
Natural gas is another popular fuel option for standby diesel generator sets. It is a clean-burning fuel that is composed mainly of methane. Natural gas has several advantages over diesel fuel:
- Low Emissions: Natural gas produces lower levels of emissions compared to diesel fuel, including NOx, PM, and CO. This makes it a more environmentally friendly option.
- Quiet Operation: Natural gas generators are generally quieter than diesel generators, making them a better choice for residential areas or other noise-sensitive environments.
- Cost: Natural gas is generally less expensive than diesel fuel, which can result in lower operating costs over time.
- Availability: Natural gas is widely available in many areas, and it can be supplied through a pipeline or stored in a tank.
However, natural gas also has some disadvantages:
- Lower Energy Density: Natural gas has a lower energy density compared to diesel fuel, which means it requires more fuel to produce the same amount of power. This can increase the size and cost of your generator.
- Dependence on Infrastructure: Natural gas generators require a reliable supply of natural gas, which means they are dependent on the availability of a pipeline or storage tank. This can be a problem in areas where natural gas is not readily available.
- Safety Concerns: Natural gas is a flammable gas, and proper safety measures must be taken when using it. This includes ensuring that the generator is installed in a well-ventilated area and that the gas supply is properly regulated.

Propane
Propane is a liquefied petroleum gas (LPG) that is commonly used as a fuel for standby diesel generator sets. It is a clean-burning fuel that is composed mainly of propane and butane. Propane has several advantages over diesel fuel and natural gas:
- High Energy Density: Propane has a high energy density, which means it can produce a large amount of power per unit volume. This makes propane generators more efficient and capable of providing continuous power for extended periods.
- Low Emissions: Propane produces lower levels of emissions compared to diesel fuel, including NOx, PM, and CO. This makes it a more environmentally friendly option.
- Quiet Operation: Propane generators are generally quieter than diesel generators, making them a better choice for residential areas or other noise-sensitive environments.
- Availability: Propane is widely available in many areas, and it can be stored in a tank. This makes it a convenient option for standby generators.
However, propane also has some disadvantages:
- Cost: Propane is generally more expensive than natural gas, which can increase the operating costs of your generator over time.
- Storage Requirements: Propane must be stored in a tank, which can take up a significant amount of space. This can be a problem in areas where space is limited.
- Safety Concerns: Propane is a flammable gas, and proper safety measures must be taken when using it. This includes ensuring that the generator is installed in a well-ventilated area and that the propane tank is properly maintained.
Biodiesel
Biodiesel is a renewable fuel that is made from vegetable oils, animal fats, or recycled cooking oil. It is a clean-burning fuel that can be used in diesel engines without any modifications. Biodiesel has several advantages over diesel fuel:
- Renewable: Biodiesel is a renewable fuel that is made from sustainable sources. This makes it a more environmentally friendly option compared to diesel fuel.
- Low Emissions: Biodiesel produces lower levels of emissions compared to diesel fuel, including NOx, PM, and CO. This makes it a more environmentally friendly option.
- Compatibility: Biodiesel can be used in diesel engines without any modifications, which makes it a convenient option for standby generators.
- Local Availability: Biodiesel can be produced locally, which can reduce the dependence on foreign oil and support the local economy.
However, biodiesel also has some disadvantages:
- Cost: Biodiesel is generally more expensive than diesel fuel, which can increase the operating costs of your generator over time.
- Storage Requirements: Biodiesel has a shorter shelf life compared to diesel fuel, which means it must be stored properly to prevent degradation. This can be a problem in areas where the temperature is high or the humidity is low.
- Performance: Biodiesel has a lower energy density compared to diesel fuel, which means it requires more fuel to produce the same amount of power. This can reduce the efficiency of your generator.
Choosing the Right Fuel
When choosing the right fuel for your standby diesel generator set, there are several factors to consider:
- Power Requirements: The power requirements of your generator will determine the amount of fuel it needs to produce the required power. You should choose a fuel that can provide the necessary power output for your specific application.
- Availability: The availability of the fuel in your area is an important factor to consider. You should choose a fuel that is readily available and can be easily refueled when needed.
- Cost: The cost of the fuel is another important factor to consider. You should choose a fuel that is cost-effective and can provide the best value for your money.
- Environmental Impact: The environmental impact of the fuel is an important consideration, especially if you are concerned about reducing your carbon footprint. You should choose a fuel that produces lower levels of emissions and is more environmentally friendly.
- Safety: The safety of the fuel is an important consideration, especially if you are using the generator in a residential area or other noise-sensitive environment. You should choose a fuel that is safe to use and does not pose a significant risk of fire or explosion.
Conclusion
In conclusion, standby diesel generator sets can use a variety of fuels, including diesel fuel, natural gas, propane, and biodiesel. Each fuel has its own advantages and disadvantages, and the choice of fuel will depend on your specific needs and requirements.
