A review on the recently developed methods of the methane emission inventory estimation in the natural gas distribution network

As a clean energy source, the natural gas emits about 50 percent less CO2 than coal when burned normally. On the other hand, the global warming potential of the methane is 86 times greater than CO2 on a 20-year time frame. An increase in the methane emission can eliminate the advantage of minimal carbon dioxide emitted in the natural gas combustion. Hence, methane emission as an important environmental issue, has been evaluated in the various studies. Today, it has accelerated to progress of the mobile methane leak measurement in the various sectors of the natural gas industry. The most important achievement of this idea is increasing of the emission detection rate and also providing the potential for maximum coverage of leakage finding in the natural gas distribution network. In this study, the effort has been made to evaluate the new ideas of emission detection used in natural gas distribution infrastructure.
