They report that these methane hydrates were found in «coarse - grained sand - rich depositional systems in the Krishna - Godavari basin» and are more easily
mined than the methane hydrates off the United States continental shelf.

Banks suggests that reconciling those rights agreements could lead to a shift in the way coal
mining companies view
methane gas, treating it as a potential source of revenue rather
than a fugitive gas to be dealt with as a safety or environmental concern.
Perhaps someone with a better background on geology could explain why there's so much more
methane extracted per unit of coal resource in coalbed
methane than is vented in regular coal
mining.
Trillions of cubic feet of coalbed
methane are pumped in the US each year from an industry that is much smaller
than coal
mining.
This peer - reviewed study by a pair of researchers at Rice University in Houston shows that while fracking - produced water shouldn't be allowed near drinking water, it's less toxic
than similar waste from coal - bed
methane mining.
Trillions of cubic feet of coalbed
methane are pumped in the US each year from an industry that is much smaller
than coal
mining.
Perhaps someone with a better background on geology could explain why there's so much more
methane extracted per unit of coal resource in coalbed
methane than is vented in regular coal
mining.
A nearby circuit showed higher
methane upwind of a pad
than downwind, indicating a source outside the target area, possibly from nearby
mine vents.
Nader said, «We do not need nuclear power... We have a far greater amount of fossil fuels in this country
than we're owning up to... the tar sands... oil out of shale...
methane in coal beds...» Sierra Club consultant Amory Lovins said, «Coal can fill the real gaps in our fuel economy with only a temporary and modest (less
than twofold at peak) expansion of
mining.»
Methane is 34 times stronger than carbon dioxide at trapping heat over a 100 - year period and 86 times stronger over 20 years; roughly 10 percent of all US methane emissions come from coal
Methane is 34 times stronger
than carbon dioxide at trapping heat over a 100 - year period and 86 times stronger over 20 years; roughly 10 percent of all US
methane emissions come from coal
methane emissions come from coal
mining.
But the findings of the Alberta study clearly suggest that actual
methane emissions from the upstream oil and gas sector (excluding
mined oil sands) are likely to be at least 25 to 50 per cent greater
than estimated.
Another remnant of Germany's coal
mining past is invisible: coal
mine methane, which can build - up inside the
mining shafts for decades after their closure.Not only does
methane pose an explosion hazard, it is also a very potent greenhouse gas, being about 20 times more effective in trapping heat in the atmosphere
than carbon dioxide.
Included in life cycle carbon are substantial
methane leaks from natural gas production and pipelines, the energy for drilling,
mining, transport, refining, and disposal that are much more significant for fossil fuels and nuclear energy
than for renewables.
Methane, which comes from the stomachs of cattle and sheep, from thawing tundra, from food rotting in landfill and from drilling for oil and
mining, is a greenhouse gas that is much more dangerous
than carbon dioxide.
The coal
mining process releases
methane, which is 87 more potent as a greenhouse gas
than CO2 over a 20 year period (4).
Overall, the study found that
methane emissions from all U.S. sources — including agriculture, oil and gas development, landfills, and coal
mining — are 50 percent greater
than estimates from the EPA Inventory, which recently lowered its estimate of
methane emissions from oil and gas systems.
