It is a fossil fuel, meaning that it is derived from organic material buried in the earth millions of years ago. The main component of natural gas is methane. The popularity and use of clean natural gas has increased dramatically over the past 50 years as pipeline infrastructure has been ...
aMethane burns more cleanly than any other fossil fuel. Methane is cheap, and it comes from domestic sources; a U.S. source of about 800 trillion cubic feet (Tcf) of methane has been discovered in coalbeds. This significant energy source has been converted from a centuries-old mining hazar...

The majority of American hydrogen for industrial purposes, 11 million tons of it annually, is produced by steam methane reforming of natural gas (SMR) — which of course is a fossil fuel and thus produces CO2. It’s cheap and abundant here, but environmental activists are dead set against ...
根据文章第三段中“A big step would be to stop millions of tons of methane from leaking out of fossil fuel industry each year. Natural gas operators will be able to sell more gas in exchange for an acceptable investment so as to monitor and repair leaks.(一项重大举措是阻止化石燃料工业每年...
适应性训练(94)Natural gas is a fossil fuel. Like other fossil fuels such as coal and oil, natural gas formsfrom the plants, animals and microorganisms(1)lived millions of years ago.There are several different theories to explain (2)fossil fuels are formed. Asplants, animals and microorganisms...
fuels, the fuel created by plant and animal remains over millions of years.Burning it releases fewer pollutants than oil or coal.The gas is mainly methane (甲烷).It produces half the carbon dioxide of other fossil fuels.So it may help cut the production of carbon gases linked to climate ...
According to Di-Jia Liu, a chemist at the Argonne National Laboratory in the US, the carbon atoms (原子) in CO2 and the hydrogen (氢) atoms in water can be combined to make methane (甲烷) or ethanol (乙醇). Th...
