A portable natural gas generator is a great option if you have an existing natural gas line running to your home. Find out how these work and which models are the best.


A portable natural gas generator could be one of the best backup devices during power outages. It uses commonly available natural gas as its fuel, which is a mixture of different gases, methane being the primary ingredient. Natural gas is known to be one of the cleanest fuels, as it does not leave any residue, and is high in the output of heat and light.

How does a Generator Using Natural Gas Work?

A portable natural gas generator uses the kinetic power and heat generated by pressurized jets of hot gas to produce electricity. The force produced by these energies, move electric charges in the windings of the motor due to electromagnetic induction, and electric current is supplied through the circuit.

However, each type of fuel brings with it a set of advantages and disadvantages, which is reflected in the generator. Therefore, before choosing a generator with a particular fuel type, it is wise to weigh the pros and cons, and opt for one that best suits your requirements.

Advantages of Portable Natural Gas Generators

  • Most houses already have a natural gas connection, as it is a popular domestic fuel. Hence, it is always available, and there is no fear of the fuel running out.
  • When the power goes out, many gas stations may not being working, so if you have a gasoline powered generator and don’t have fuel stored, you may find yourself out of luck in trying to buy more fuel at gas stations. Also, if the storm is bad, roads may be impassable, making a trip to the station out of the question. Natural gas should always be available.
  • As the gas is always available through the pipeline, there is no need to stock it in pressurized cylinders. Liquid fuels also pose the same problem of storage, and there is always the question of their safety due to their highly flammable and explosive nature.
  • Natural gas burns without leaving residue, and hence there are hardly any emissions from your generator; whereas in diesel generators there is always the problem of emissions and wet stacking.
  • Due to the clean burn of the gas, there is no problem during cold start, whereas diesel forms gum compounds that poses various problems.

Main Disadvantages

  • Natural gas may not be available during severe natural disasters that can cause disruptions in the pipelines. Although precautions are taken for the pipeline, earthquakes can rupture these supply lines causing the inflammable gas to escape. Hence, there is a possibility of not being able to use the generator when you most need it.
  • The investment and overall cost of running this generator is quite high. There is the initial investment of getting a connection and the related plumbing of the gas lines. Secondly, the cost of this generator itself is more, compared to generators that run on gasoline. Lastly, natural gas is not considered an efficient fuel for a generator as it produces about 30% less electricity than generators running on gasoline. The running cost can be quite high when the power requirement is large.
  • Generators running on any kind of natural gas have a lower life expectancy, compared to generators using liquid fuel. Some natural gas generators are known to last only for about 500 hours.

Popular Portable Natural Gas Generator Models

If you’re going to buy a portable generator instead of a stationary generator then it’s always good to have multiple power options for the machine other than just natural gas. If you want to use your generator out camping for example, you aren’t going to find a natural gas line to hook it up to. Therefore you need it to be able to run on unleaded gas or propane. That’s why when I looked for the best portable natural gas generators I wanted to find ones that offered flexibility in fuel options. Here are three models that fit the bill.

Powerland PD3G10000E Tri Fuel Portable Generator
