Comments Off on Methane Hot Spot in U.S. Predates Fracking Boom, Study Says

An area in the U.S. Southwest that’s about half the size of Connecticut has emitted the country’s largest concentration of methane, a potent greenhouse gas, according to a new analysis of satellite data. The study, which was released jointly by the American Geophysical Union and NASA, found that between 2003 and 2009, the area released…

It is often called “fire ice”:  Around the world, cage-like lattices of water molecules trap untold stores of methane gas.  Petroleum engineers have been familiar with these frozen compounds—properly known as methane hydrates—for years, because they block the flow of oil in pipelines. The effects of methane hydrates were highlighted in 2010, when British Petroleum’s…

Comments Off on Simple Fixes Could Plug Methane Leaks from Energy Industry, Study Finds

Almost all of the climate-affecting methane leaks from the oil and gas infrastructure could be reduced at relatively little expense, often by simply tightening bolts or replacing worn seals, suggests a new study by the Boston-based Clean Air Task Force released today. (See related story: “Green Fracking? 5 Technologies for Cleaner Shale Energy.”) The report…

Comments Off on Methane Emissions Far Worse Than U.S. Estimates, But Study Concludes Natural Gas Still Better Than Coal

Emissions of the potent heat-trapping gas, methane, the main component of natural gas, are likely 50 percent higher than U.S. government has estimated in its official greenhouse gas inventory, says a new study that is the most comprehensive effort yet to assess the problem. But the team of scientists, after reviewing more than 200 earlier…

A new study challenges our understanding of natural gas as a clean fuel, and raises new questions about the U.S. energy boom. Sure, natural gas (or methane, its main component) burns with less pollution than coal, but release it directly to the atmosphere and it is a highly potent greenhouse gas–at least 25 times worse…

Global greenhouse gas emissions are higher than ever. What’s to be done? “Redrawing the Energy-Climate Map,” a special report [pdf] by the International Energy Agency (IEA), was released on Monday, and the findings are sobering. (See related story: “What’s Behind the New Warning on Global Carbon Emissions?“) In 2012 energy-related, global carbon dioxide (CO2) emissions…

Water samples in Pennsylvania suggest there may be natural pathways for contamination. Drinking water contamination from horizontal drilling and hydraulic fracturing — a k a fracking — for natural gas in Pennsylvania, does it occur? No, say the gas companies (and many geologists). A new paper adds a “but.” Many Say It Can’t Happen There…

Our neighbor to the south plans to swim against the tide. The tide in question is the world’s rising emissions of carbon dioxide (CO2), and with the March 2012 data from the Mauna Loa Observatory now in, that tide has risen to new heights. At 394.45 parts per million, it is the highest monthly average…

Comments Off on Air Pollution from Fracked Natural Gas Wells Will Be Regulated Under New U.S. Rules

Under a new rule from the U.S. Environmental Protection Agency, new oil and gas wells that are hydraulically fractured—or “fracked”—will have to use new equipment to capture the gases that escape, rather than releasing them into the air or burning them off. Hydraulic fracturing has been in use since the 1950s, but in the past…

Natural Gas for Cars

Does it make climate sense to drive cars with natural gas? Our nation appears to be rapidly moving to a natural gas-powered economy. Advances in hydraulic fracturing (fracking) and horizontal drilling have made huge deposits of natural gas in shale and tight sands commercially viable. (See “Hydrofracturing: An Energy Revolution.”) Suddenly the United States is…
