And because methane is hidden and inodorous, monitoring it can be tough and high-priced. As a result, researchers and environmental activists claim that the industry probably releases much more than official government estimates show.
Methane also leaks from coal mines – actually more methane than it is released during natural gas production, which is mainly methane. Ember, Think Tank with pure energy, put it Great visual interactive showing how it happens.
The low version is that the methane is embedded in coal deposits, and when the miners dig, to reveal the coal seams, the gas escapes and still does as long after the coal mine reaches the end of his operational life. Because coal miners focus on coal extraction, they often do not follow how much methane they release or pay attention.
According to Ember, methane emissions from coal mines can be 60 percent higher than official values. Abandoned coal mines are particularly harmful, emitting more than abandoned oil and gas wells. The combined, methane emitted from coal mines around the world each year has the same impact of warming on the climate as the total annual emission of carbon dioxide in India.
Concerned with gaps in the data, some non-profit organizations have taken on themselves to get a better image of methane emissions on a global scale using ground sensors, air monitors and even satellites. In 2024, the Environmental Defense Fund launched Methanesat, which transfers instruments that can measure the production of methane from miniature, tactful sources in a wide area.
Ritesh GautamThe main scientist Methanesat explained that the project revealed some of the main overlooked methane emitter. Since the launch of Methanesat, he discovered that in the US most methane emissions do not come not only from a few gigantic oil and gas drilling places, but from many small wells that emit less than 100 kilograms per hour.
“Brzega wells produce only 6 to 7 percent [oil and gas] In the United States, but disproportionately, they constitute almost 50 percent of emissions related to the production of oil and gas in the US, “said Gautam.” These objects produce only less than 15 barrels of oil equivalent per day, but then there are over half a million of them dispersed around the USA. “
There are ways to stop methane emissions, but we don’t apply them
The good news is that many tools containing methane from the energy industry are already available. “About 70 percent of methane emissions from the fossil fuel sector can be avoided in the case of existing technologies, often at low costs,” according to the IEA methane report.
For the oil and gas industry, this can mean something as elementary as using better fittings in pipelines to limit leaks and installation of methane capture systems. And because methane is fuel, the sale of the saved methane can balance the cost of modernizing the equipment. Permission to go to the atmosphere is a waste of money and contributes to insulation.
