Methane scare is evaporating
Whoops. It looks like another one of those canards raised by some environmental groups about the supposed dangers of hydraulic fracturing associated with gas drilling is losing its scare power.
Methane gas does not appear to be a major pollutant emitted as a result of gas drilling and fracking, according to a new study, the results of which were published this week by the Proceedings of the National Academy of Sciences.
Methane gas, which is believed to be a more potent climate-change pollutant than carbon dioxide, has been red-flagged by a few groups trying to stop natural gas drilling. They use it to counter arguments from natural gas advocates and many conservationists that natural gas is cleaner than coal and less worrisome when it comes to climate change.
“Natural gas is also a major threat to our climate,” claims the Sierra Club website. “Total greenhouse gas emissions from natural gas are nearly identical to coal, once methane leakage is taken into account.”
The website of a group called Frack Attack argues, “Fracking-enabled oil and gas development leaks methane at every step from extraction to transport.”
The study conducted by the University of Texas and released this week doesn’t say drilling and fracking for natural gas is methane-free. However, it does state that testing done by the researchers shows the process does not emit the immense amounts of methane gas that some people had feared.
As the Associated Press article in The Daily Sentinel Tuesday noted, even one of the first scientists to raise concerns about potentially large amounts of methane emissions called the results of the study “good news.”
Some fracking critics will no doubt pooh-pooh the study because it was paid for in large part by energy companies, even though the Environmental Defense Fund also helped pay for it and the scientists involved said they controlled how the research was performed, and where.
Others may note that some previous studies have showed higher levels of methane emissions at some well sites, but that is an argument for better operating procedures and monitoring, not for halting drilling and fracking altogether.
Natural gas remains a critical commodity to help this country meet our energy needs in a cost-effective manner and to continue to reduce our emissions of CO2, as we have been doing for at least five years.
Equally important, for Americans sick of seeing this country get drawn into every Middle Eastern border clash and civil war, natural gas is critical to moving our nation further away from dependence on oil from that troubled region.
There are potential environmental hazards associated with drilling and fracking, but they can be controlled. And in the case of methane, those hazards now appear far less worrisome than some folks have led us to believe.
