Normalgas
Normalgas is a hypothetical gaseous energy carrier used in energy modeling and academic literature to represent a baseline natural gas mixture. As a modeling construct, it provides a standard reference composition against which alternative fuels and process configurations can be compared. Because it is not a real substance, its exact formulation varies by study, but it is typically methane-dominated and designed to resemble conventional natural gas within common pipeline and combustion standards.
In most definitions, Normalgas contains roughly 60–90% methane, with ethane, propane, and heavier hydrocarbons in smaller
As a concept, Normalgas is not produced or traded physically. It is generated digitally in datasets or
It is used in optimization of energy systems, reliability planning for gas networks, emissions accounting, and
Properties mirror those of real methane-rich gases, so safety and environmental concerns entail flammability and methane
The term appears in modeling literature from the late 20th century onward as a convenient referent for
