What is the science and technology behind natural gas?
What is the science and technology behind natural gas?
The remains of ancient plants and animals decay under the intense heat and pressure created by the layers of sand, silt, rock and water above them. Over time, this geologic pressure cooker causes the decaying materials’ carbon atoms to break down, forming thermogenic natural gas.
How does the natural gas work?
Natural gas power plants generate electricity by burning natural gas as their fuel. All natural gas plants use a gas turbine; natural gas is added, along with a stream of air, which combusts and expands through this turbine causing a generator to spin a magnet, making electricity.
How does natural gas exist in nature?
Natural gas is a fossil fuel. Like other fossil fuels such as coal and oil, natural gas forms from the plants, animals, and microorganisms that lived millions of years ago. As plants, animals, and microorganisms decompose, they are gradually covered by layers of soil, sediment, and sometimes rock.
What does natural gas mean in science?
Definition: Natural gas is a mixture of gases which are rich in hydrocarbons. All these gases (methane, nitrogen, carbon dioxide etc) are naturally found in atmosphere. Description: Natural gas is mainly used as fuel for generating electricity and heat.
What makes natural gas rise to the surface?
Natural gas is a product of decomposed organic matter, typically from ancient marine microorganisms, deposited over the past 550 million years. After natural gas forms, it will tend to rise towards the surface through pore spaces in the rock.
What makes up the natural gas in the atmosphere?
In its unprocessed form, natural gas is actually a mixture of naturally occurring flammable gases. The mix varies from source to source, but its chief ingredients include methane, butane and propane. Like coal and oil, natural gas can form deep underground.
What do you need to know about natural gas?
You can learn more about natural gas in the following comprehensive suite of pages, which detail the many aspects of natural gas, from formation to extraction to end use, including associated environmental impacts.
How does the decomposition of organic matter produce natural gas?
Either will tell you that organic matter such as animal waste produces significant amounts of gas as it decomposes, thanks to methanogenic organisms: bacteria that eat the waste and produce methane as their own waste product. This biogenic natural gas (or biogas) formed from the decomposition process presents a tremendous renewable resource.

What makes natural gas different from other fuels?
In fact, ancient organic matter becomes one fuel or the other depending on its depth and temperature: Deeper deposits, exposed to more of the Earth’s heat and pressure, have much higher concentrations of natural gas. But natural gas can also form in a much shorter, more immediate period of time.
How is natural gas used in the United States?
Natural gas is a versatile fossil fuel that we use for heating, cooking, electricity production, transportation, and as an industrial feedstock. In 2012, it made up 30 percent of the U.S. energy mix, and it continues to be a readily available domestic resource as a result of recent discoveries and advances in extraction technology.
