In deciding how best to meet the world’s growing needs for energy, the answers depend crucially on how the question is framed. Looking for the most cost-effective path provides one set of answers; including the need to curtail greenhouse gas emissions gives a different picture. Adding the need to address looming shortages of fresh water, it turns out, leads to a very different set of choices.
Methane hydrates are a potential energy source, but they are also a potential source of global warming. A pair of cooperating microbes on the ocean floor "eats" this methane in a unique way, and a new study provides insights into their surprising nutritional requirements. Learning how these methane-munching organisms exist in extreme environments could provide clues about how the deep-sea environment might change in a warming world.
According to a study published by scientists at the Potsdam Institute for Climate Impact Research, the strategy of assigning a price to global carbon nanotubes emissions could generate a revenue of $32 trillion over the 21st century, exceeding by far the $12 trillion of lost profits from fossil fuel owners.
The Ukrainian government signed a shale gas production-sharing agreement with the Chevron, as the country strives for energy independence from neighboring Russia. Energy Minister Eduard Stavitsky said that under the deal, Chevron will initially invest $350 million into exploratory and drilling work in the Oleska field in western Ukraine. Total investment could surpass $10 billion over 50 years.
Gas and oil deposits in shale have no place to hide from an Oak Ridge National Laboratory technique that provides an inside look at pores and reveals structural information potentially vital to the nation’s energy needs. The research could clear the path to the more efficient extraction of gas and oil from shale.
In waters off Long Beach, Seal Beach and Huntington Beach—some of the region's most popular surfing strands and tourist attractions—oil companies have used fracking at least 203 times at six sites in the past two decades. This discovery made from drilling records and interviews shows that offshore fracking is more widespread and frequent that state officials believed.
According to a recent study led by scientists at Duke Univ., elevated levels of radioactivity, salts and metals have been found in river water and sediments at a site where treated water from oil and gas operations is discharged into a western Pennsylvania creek.
According to research published this week drilling and fracking for natural gas don't seem to spew immense amounts of the greenhouse gas methane into the air, as has been feared. The study, mostly funded by energy interests, doesn't address other fracking concerns about potential air and water pollution, but does generally with government estimates.
A formal partnership agreement to encourage collaborative research, build educational and workforce development programs and inform policy endeavors regarding renewable energy efforts has been signed by Sandia National Laboratories and Arizona State Univ. The move will facilitate multidisciplinary collaborations and help them secure research funding.
Supporters and opponents of fracking in the political hotbed where New York's natural gas deposit lies lined the route being taken Friday by visiting President Barack Obama, shouting messages for him while trying to pressure Gov. Andrew Cuomo as he weighs whether to allow the practice in New York.
California regulators on Thursday were set to take up offshore fracking after revelations that the practice had quietly occurred off the coast since the late 1990s. The California Coastal Commission added the issue at the last minute to its agenda during its monthly meeting.
Last week's blowout on a natural gas rig off the Louisiana coast could shift regulators' focus to shallow-water drilling and make an overhaul of safety equipment regulations more likely. The rig, owned by Hercules Offshore and operated under contract to Walter Gas & Oil, spewed gas July 23 that eventually ignited. The fire damaged the Hercules 265, which was within days of wrapping up its drilling contract.
Ford soon will offer a natural gas version of its F-150 pickup truck, the most popular vehicle in America. The company is the first Detroit automaker with that option in a light-duty pickup truck. Ford, General Motors and Chrysler already have natural gas-powered heavy-duty trucks.
A landmark federal study on hydraulic fracturing, or fracking, shows no evidence that chemicals from the natural gas drilling process moved up to contaminate drinking water aquifers at a western Pennsylvania drilling site. After a year of monitoring, the researchers found that the chemical-laced fluids used to free gas trapped deep below the surface stayed thousands of feet below the shallower areas that supply drinking water
Americans used more natural gas, solar panels and wind turbines and less coal to generate electricity in 2012, according to the most recent U.S. energy charts released by Lawrence Livermore National Laboratory. Natural gas use is up in the electricity generation sector, where it has basically substituted directly for coal, while sustained low natural gas prices have prompted a shift from coal to gas in the electricity generating sector.
Each year, the Lawrence Livermore National Laboratory releases energy flow charts that track the nation's consumption of energy resources. According to the most recent charts, Americans used more natural gas, solar panels and wind turbines and less coal to generate electricity in 2012.
A research collaboration agreement has been formed between imaging company FEI and the University of Oklahoma to establish an oil and gas center of excellence. Called the FEI-OU Pore Scale Characterization Laboratory, the center will focus on the development of routine quantitative methods to classify shales in the economic assessment of tight oil and gas plays.
A number of utilities and consumer groups say they support proposed rules that would require Mississippi electric and gas utilities to implement programs to save energy. However, Mississippi Power Co. says it opposes the rules because bills could rise for customers who don't make homes or businesses more efficient. The Public Service Commission began considering energy-efficiency rules in early 2010.
Sandia National Laboratories and SRI International will join forces to explore, test and evaluate a broad range of hydrogen and natural gas fuel systems and components for transportation applications under a new agreement. The five-year memorandum of understanding is the first agreement in Sandia’s new Center for Infrastructure Research and Innovation, an alternative fuel research and innovation facility.
One of America's corporate giants is investing billions of dollars in the new boom of oil and gas drilling, or fracking. General Electric Co. is opening a new laboratory in Oklahoma, buying up related companies, and placing a big bet that cutting-edge science will improve profits for clients and reduce the environmental and health effects of the boom.
Hydraulic fracturing for natural gas hasn't contaminated drinking water wells in Arkansas, according to a new study, but researchers said the geology there may be more of a natural barrier to pollution than in other areas where shale gas drilling takes place.
Scientists sampling 127 shallow drinking water wells in areas overlying Fayetteville Shale gas production in north-central Arkansas found no evidence of groundwater contamination. The team of scientists at Duke University and the U.S. Geological Survey (USGS) analyzed the samples for major and trace elements and hydrocarbons, and used isotopic tracers to identify the sources of possible contaminants.
Most Michigan and Pennsylvania residents say fracking is good for the economy, but have concerns about chemicals used and other environmental risks, according to a University of Michigan survey. Fracking is the common term for hydraulic fracturing, which involves injecting a mixture of water, sand, and chemicals deep into the ground through encased wells at high pressure to create and expand fractures in the shale rock.
A domestic natural gas boom already has lowered U.S. energy prices while stoking fears of environmental disaster. Now U.S. producers are poised to ship vast quantities of gas overseas as energy companies seek permits for proposed export projects that could set off a renewed frenzy of fracking.
Chemical engineers have identified a new mechanism to convert natural gas into energy up to 70 times faster. The technique improves on chemical looping, in which a solid, oxygen-laden material—called an “oxygen carrier”—is put in contact with natural gas to cause combustion. The newly developed oxygen carrier shuttles oxygen atoms into the natural gas very efficiently.
