Is There A Portable Generator That Runs On Natural Gas?

Is there a portable generator that runs on natural gas? Yes, numerous generator manufacturers are coming up with diverse sizes of portable generators that run on natural gas.

With the increase in concern about global warming, generators that run on natural gas are turning out to be the most ideal in this age.

Such generators largely contribute to the lowering of carbon footprints. Even though several portable generators are strictly built to run on natural gas, most brands in the market are dual and tri-fuel generators.

As of 2019, dual fuel portable generators with a capacity to run on natural gas accounted for 43% of sales of generators in the US alone.

However, environmental protection agencies discourage diesel as a fuel source because of its high carbon emissions, making it an unclean energy source. Read on to learn more about portable generators that run on natural gas.

What is the Difference Between Natural and Propane Gas?

These two gases have a range of similarities;

  • They are both odorless
  • Both burn clean
  • They are both odorless and colorless.

Natural gas is a fossil energy source, just like gasoline and diesel. However, natural gas has a high methane gas content as the key component, while carbon and hydrogen atoms are smaller amounts.

Propane gas, also known as LPG (liquefied petroleum gas), is a co-product of the process of reefing crude oil and a byproduct of natural gas.

In terms of energy efficiency, a cubic foot of natural gas releases 1030 BTUs while the same amount of propane gas produces 2516 BTUs. Therefore, propane gas is 2.5 times more superior to natural gas.

While both energy sources are eco-friendly, propane gas is the cleanest burning fuel among fossil fuels; natural gas comes behind.

The superiority of propane gas is what makes most portable generator manufacturers make most gas generators propane-powered.
