Natural Gas FAQ

Have you ever wondered why natural gas flames are blue? Or who first discovered natural gas? Now you can get answers to these and all your natural gas-related questions.

In its natural state, natural gas has no odor. Utility companies add a chemical odorant called “mercaptan” to natural gas to help make gas leaks easier to notice. If you have a natural gas stove, you may have smelled this rotten egg odor when the pilot light has gone out.
Natural gas is called “natural” because when this type of gas was first discovered, it could be used directly from the ground in its natural state, without any processing. Today, gas utilities process natural gas by removing water, sand, and other compounds so that when the gas is delivered to your home it will burn as cleanly and efficiently as possible. And in its natural state gas has no odor, so that’s why companies add a harmless but stinky chemical to it; the odor helps people smell a leak that otherwise, in the gas’s natural state, doesn’t smell.

More homes in the U.S. are heated by natural gas than by electricity.

Vehicles that run on natural gas instead of gasoline are called natural gas vehicles (NGVs). There are about 175,000 NGVs on U.S. roads today and over 23 million worldwide. NGVs are a popular transportation choice because they run cleaner than other vehicles. Compared to gasoline- or diesel-powered vehicles, they produce much lower levels of pollutants and cost less to maintain. Also, natural gas costs, on average, one-third less than conventional gasoline at the pump.

A natural gas flame burns hotter than a campfire. In general, cooler flames appear yellow, orange, or red, while hotter flames look blue or white. (Flecks of orange in your gas flames are OK, but if the flame is yellow, large, and flickering, the appliance may need a safety adjustment by a qualified repair person.)

The ancient Chinese were the first to discover underground deposits of natural gas. In 600 BC, Confucius wrote of wells 100 feet deep yielding water and natural gas along the Tibetan border. The Chinese piped the gas to where it was needed through long, hollow bamboo stalks.

Yes. In 1626, French explorers found Native Americans igniting gases that were seeping into and around Lake Erie.
Natural gas travels through high-pressure transmission pipelines at up to 30 miles per hour.
