Natural gas production in the US is growing and setting new records. The gas flows go across a network of more than 200 pipelines that stretch over 300,000 miles.

You might be questioning what does all this capacity means. It’s dependability. Because the owners of natural gas generators can rest knowing the plenty of fuel. 

They know that they have enough fuel for power generation in need of emergency.

According to a study by Nevada’s public utility commission, it’s easy to deliver natural gas in an emergency without even storing it through pipelines.

It is found that there are only three natural gas outrages that happen yearly.

Natural gas lines are deep from ground level that they are safe from natural disasters. The underground safety of the lines protects them from the above-ground utilities.

That’s why many industries think that gas generators are more dependable than others.

3. Clean Burning

There is no doubt in saying that natural gas takes the title of the cleanest burning fossil fuel. It is best to use for power generation as it produces less Sulphur and nitrogen.

Natural gas generators have almost 90% fewer emissions than diesel generators.

The most beneficial thing about natural gas is that it can lower the impact of toxic emissions on the environment.

Natural gas is environment friendly as it uses field gas.

Natural gas generators equipped with raw gas are best for power buildings. Gas generators can reduce the power generation that comes from diesel generators.

4. Cost-Effective

A natural gas generator is cost-effective as compared to a diesel generator. Natural gas generators cost you half of what diesel generators do. 

According to US Energy Information Administration, there are 137,381 Btu found in a gallon of diesel.

The average cost for this is $3, so if you want to get one million Btu, you need 7.5 gallons of diesel. It will cost you a total of $22.

If we talk about natural gas, it contains 1,036 Btu in a cubic foot, which only costs $0.1286 as of right now.

If you want to get one million Btu, you need 965 cubic feet, which will only cost you $13.

But, natural gas generators need more maintenance over the long-term. It can also need initial outlays to install, and buy-in cases when running new gas lines are crucial.

But. Still, the low cost of natural gas helps you cover the price over the long-term period.

5. Easy Accessibility

Natural gas is accessible in case of emergency, but diesel fuel refill can be difficult at times of need. In case of natural disasters like flooding, there is no guarantee of a diesel fuel supply.

Moreover, natural gas is accessible because you don’t need to manage it. However, it’s crucial to maintain diesel fuel tanks as their shelf life is only 12 months.

There are many other challenges that you can face in diesel-based generators. 

Another thing about natural gas generators is that you don’t need to do hectic and costly cleanups.

There can be diesel spills because of or other defaults that can cause expensive cleanup.

Can Portable Generators Run on Natural Gas?

Portable generators run on gasoline and need large spaces. But, there are many portable generators available that can run on natural gas.
