Specific energy of methane

The Specific Energy and Energy Density of some common fuels and combustible compounds are given below. Note the values are negative as they represent the energy lost from the substance as it burns. The surrounding environment will gain this amount of energy. See more Specific energy and energy density are useful measures of the energy that will be released from a given weight or volume of fuel when it is burned. This article … See more The Heat of Combustion of a product measures the energy released when that substance is burned in air, this information is often presented in units … See more WebWe have constructed an atmospheric inversion framework based on TM5-4DVAR to jointly assimilate measurements of methane and δC-13 of methane in order to estimate source-specific methane emissions. Here we present global emission estimates from this framework for the period 1999–2016. We assimilate a newly constructed, multi-agency …

Methane is used in industrial chemical processes and may be transported as a refrigerated liquid (liquefied natural gas, or LNG). While leaks from a refrigerated liquid container are initially heavier than air due to the increased density of the cold gas, the gas at ambient temperature is lighter than air. Gas pipelines distribute large amounts of natural gas, of which methane is the principal component.
