What’s the Difference Between Natural Gas and Diesel Generators?

Only a few years ago, traditional logic for generator sets (gensets) held that:

Diesel generators = reliable and inexpensive but also noisy, loud and messy.
Natural gas generators = expensive and temperamental but also quieter and cleaner.
Diesel fuel is the traditional choice for commercial and industrial standby power, but is by no means the only choice.  In the past, gaseous fuels have been avoided in industrial applications based upon cost, power density and perception of durability and fuel reliability.  That is no longer the case. Today, thanks to the development of new technologies in engines, enclosures and other components, the differences between diesel and natural gas generators is no longer so clearly defined.

Natural Gas Generators

An efficient means of power generation is by using a natural gas generator. It can be used to power  emergency and portable generators and is considered to be one of the least expensive and one of the most adequate forms of fuels among the fossil fuel family for generating power.  In terms of price, coal is the only fuel that is less expensive. One of the biggest draw backs of using coal is that it’s a very dirty source of fuel.
Natural gas is typically acquired by drilling, the same process as is done for oil.  Natural gas in liquid form is taken to various holding facilities where it is converted into its gas state. Then, is made available through pipelines and it can also be purchased in cylinders.
A natural gas generator works pretty much the same as other generators.  Usually the only  difference between generators is the fuel used to power them. In this instance,  the source of fuel to start the generator is natural gas. These types of  generators are predominately used in large metropolitan areas where fuel supply is available through a  pipeline fuel delivery system.

Advantages of Using Natural Gas

The most favorable uses of  natural gas as a fuel is that it is a cleaner energy source, less expensive than other fossil fuels, and is substantially efficient.
Comparing natural gas to oil and coal, the amounts of sulfur, nitrogen, and carbon dioxide (a greenhouse gas) are considerably lower. Making natural gas one of the cleanest fossil fuels to burn.
Natural gas does not produce a strong odor, which is common with generators powered by oil or diesel fuels.
Natural gas generators are  effective in reducing costs when used to power homes because electricity from utility companies tends to be more expensive.
Aside from being cleaner burning  and cheaper to buy, natural gas is also handy in large cities because  it is delivered directly through underground pipelines to the source where it is needed. For this reason, when using natural gas powered generators, there is no need in having  fuel storage tanks.
Aside from its evident advantages, natural gas generators also have some negatives to them.

Disadvantages of Using Natural Gas

One of its advantages can also be regarded as a disadvantage.  Since natural gas does not need to be stored, as it is usually  supplied through pipelines to the site of the business or company,  during times of a  disaster or accident, the flow of natural gas may be temporarily interrupted. Finding yourself with a lack of fuel when you need power to operate your equipment during an  outage and when the regular  supply of electrical power is down, can be a major concern for keeping your business running, until that  power is restored.
Natural gas can be extremely explosive and can be a grave fire hazard should something happen to the pipeline.
Compared to diesel generators, natural gas generators:
Cost more to run.
Discharge more greenhouse gases into the air.
Also,  natural gas is a non-renewable fuel supply.
Diesel Generators
These kinds of generators can usually be divided into two primary parts: a diesel engine and an electrical generator.  Diesel generator sets  are mainly used to provide power to places that are not on a power utility grid or as a backup source in case there is some kind of  power outage or  failure.  Ships and large boats use diesel generators for all of their power and propulsion needs when they are on the water.
Diesel generators are  common for back-up emergency power. They are available in both single and three-phase, diesel generators can be used not only in medium to  large businesses,  but also for homes and small offices.

Advantages of Using Diesel

• Fuel efficiency: When it comes to making a  choice on which fuel to use, price is usually the number one factor. With the ever increasing demand and decreasing supply, when it comes to choosing which fuel to use, there will always be some kind of debate on why one is used over the other.  One of the most important keys is finding a fuel source that saves on both energy use and operating costs. Diesel generators score high on both of these points. While they are substantially more expensive than natural gas generators, also the price of diesel fuel is often more than gas, you can get a larger volume of energy out of diesel fuel. You may pay more for  diesel fuel, but the tradeoff is getting  more usable  power out of the diesel than you would for the same amount of any other gas. Fuel efficiency is the number one advantage for using a diesel generator.
• Stability: Another huge benefit for using a diesel generator is the guaranty of a stable power source. In large institutions, such as hospitals, this plays a huge role because most of the machines and devices used in them  require electrical  power to be on 24 hours a day, seven days a week and once the power goes out for some kind of stoppage or disaster, it  could mean the difference between life and death during a surgery or even keeping some kind of life-saving machine going until the main power comes back on.
• In comparing a natural gas powered generator, the diesel generator is far more efficient for several reasons such as:
Diesel engines used today are far improved versions of older models that were extremely noisy and took a lot more time to maintain.
Diesel engines are more heavy duty and dependable.
Another advantage diesel has over natural gas engines is that they do not use spark plugs or wires; helping on repair and maintenance savings.
The life expectancy of a natural gas engine is not as long as that of a diesel equivalent.
Being less flammable than other types of fuels, diesel generators score high on being safer to use. They don’t use spark plugs or wires, which eliminates the chance of a spark causing a fire.

Disadvantages of Using Diesel

A diesel generator can be more expensive to purchase compared to other types.  But, since the upkeep of  a diesel generator can be quite a bit lower, it more than makes up for it after the generator is initially purchased.
Noise is a big issue with a diesel type of  generator. While newer models are getting quieter, the older versions can still be a bit  noisy.  Diesel generators that are used in and around  larger populations may also be too noisy for residents around the vicinity of these units.
Diesel generators are large and cumbersome and have large mechanical and electrical systems that are part of the unit. As opposed to smaller and lighter generators, diesel generators are usually not very portable and user friendly.

Given the recent trend of cleaner energy fuels and less greenhouse gases, diesel is  considered a major cause of heavy pollution in most major cities and towns where it is used.


When it comes time to choose between a diesel or a natural gas generator, you’ll need to answer a few important questions:
How will your generator be used (for main or emergency power)?
What kind of budget do you have for the purchase and maintenance required for your next generator?
Both natural gas and diesel generators have their advantages and disadvantages.  With the arrival of newly developed fuel sources, such as biodiesel, these new fuels are getting less harmful on the environment and air quality, more efficient in the way these new energy sources are burned to create the power needed, and saving you on the future costs of running/maintaining these new units.
