hydrocarbon
Structures assumed by hydrogen (H) and carbon (C) molecules in four common hydrocarbon compounds.
Methane is a critical component of natural gas primarily because it serves as the mixture's main energy-providing constituent, typically comprising 50 to 90 percent of the gas depending on the source. When sold commercially for heating and other purposes, natural gas is often stripped of other liquids and consists of 85 to 90 percent methane.12
The importance of methane in this context stems from its physical and chemical properties:
- High Energy Content: Methane is highly flammable and provides a significant heating value, approximately 38 megajoules per cubic metre. This makes it an efficient fuel source for cooking, heating, and electricity generation.23
- Combustion: It burns readily in air, producing a hot, pale flame while releasing energy.1
- Versatility: Beyond its use as a fuel, methane is a vital chemical feedstock used to manufacture ammonia for fertilizers and various other organic chemicals.1
While methane is essential for energy, it is also a potent greenhouse gas, and its extraction and combustion contribute to atmospheric concentrations that impact the global climate.1
