Study: Natural Gas Power Plants Emit up to 120 Times More Methane Than Previously Estimated

Researchers at Purdue University and the Environmental Defense Fund have concluded in a recent study that natural gas power plants release 21–120 times more methane than earlier estimates. Published in the journal Environmental Science and Technology , the study also found that for oil refineries, emission rates were 11–90 times more than initial estimates. Natural gas, long touted as a cleaner and more climate-friendly alternative to burning coal, is obtained in the U.S. mostly via the controversial horizontal drilling method known as hydraulic fracturing (“fracking”) . The scientists measured air emissions at three natural gas-fired power plants and three refineries in Utah, Indiana, and Illinois using Purdue's flying chemistry lab, the Airborne Laboratory for Atmospheric Research (ALAR ) . They compared their results to data from the U.S. Environmental Protection Agency...
