Sentences with phrase «high methane leakage»

The main reason is the relatively high methane leakage from gas extraction.

Unfortunately, I believe that the rest of the world on average will have higher methane leakage rates from the hydrofracking and transmission operations than for those in the USA; which I believe, will significantly increase methane concentrations in the atmosphere over the next several decades.

Not exact matches

High levels of methane leakage from fracking have been found [163], as well as nitrogen oxides and volatile organic compounds [159].

We find (i) measurements at all scales show that official inventories consistently underestimate actual CH4 [methane] emissions, with the natural gas and oil sectors as important contributors; (ii) many independent experiments suggest that a small number of «super-emitters» could be responsible for a large fraction of leakage; (iii) recent regional atmospheric studies with very high emissions rates are unlikely to be representative of typical natural gas system leakage rates; and (iv) assessments using 100 - year impact indicators show system - wide leakage is unlikely to be large enough to negate climate benefits of coal - to - natural gas substitution.

Methane leakage rates can and probably will be lowered substantially in the future.One study found that 70 percent of total leakage from 250 wells in Fort Worth, Texas, was occurring at only 10 percent of the wells, suggesting significant potential for low - cost, high - impact intervention.

High leakage rates, a short methane GWP, and comparison in terms of heat content are the inappropriate bases upon which Howarth et al. ground their claim that gas could be twice as bad as coal in its greenhouse impact.

However, because of the high global warming potential of methane (CH4, the major component of NG), climate benefits from NG use depend on system leakage rates.

Study Finds Methane Leakage From Gas Fields High Enough To Gut Climate Benefit

High levels of methane leakage from fracking have been found [163], as well as nitrogen oxides and volatile organic compounds [159].

And while Marcellus methane leakage rates may be incredibly low, that in no way implies that these rates are high elsewhere.

Researchers noted during a webinar presentation of the study's preliminary findings in July 2017 that it was the first time long - term continuous sampling of methane from natural gas activities had occurred, and that most existing studies that use aircraft data only sample for a limited number of days, usually only one to two, and often show a higher leakage rate.

Multiple studies have indicated that natural gas is no better for the climate than coal when you consider the high rates of methane leakage in natural gas production and transport.

1 ton = ~ 7.3 barrels oil estimated Gulf oil leakage rate ~ 21600 barrels / day (5 - 40,000 depending on who's estimating) or 3000 tons / day methane emission = 1.5 e3 ton / day = 1.5 e9 g / day at 50 % methane by weight in the leak (probably a high estimate) Gulf area = 1.5 e6 km ^ 2 = 1.5 e12 m ^ 2 Gulf average depth = 1.62 e3 m Gulf volume = ~ 2.4 e15 m ^ 3
