A new analysis of global energy use, economics and the climate shows that without new climate policies, expanding the current bounty of inexpensive natural gas alone would not slow the growth of global greenhouse gas emissions worldwide over the long term, according to a study. Because natural gas emits half the carbon dioxide of coal, many people hoped the recent natural gas boom could help slow climate change.
A surprising hot spot of the potent global-warming gas methane hovers over part of the southwestern U.S., according to satellite data. That result hints that the U.S. Environmental Protection Agency and other agencies considerably underestimate leaks of methane, also called natural gas. While methane isn't the most plentiful heat-trapping gas, scientists worry about its increasing amounts and have had difficulties tracking emissions.
Penn State Univ. said Wednesday that General Electric Co. will give the school up to $10 million to create a new center for natural gas industry research. GE said the money will support research projects, equipment, and undergraduate, graduate, and postdoctoral fellowships at The Center for Collaborative Research on Intelligent Natural Gas Supply Systems. the money will be donated over the next five years and earmarked for different uses.
Researchers at the U.S. Dept. of Energy (DOE)’s Argonne National Laboratory announced a new tool for analyzing the economic impacts of building new compressed natural gas fueling stations. Called JOBS NG, the tool is freely available to the public. Mostly made up of methane, compressed natural gas is an alternative fuel for cars and trucks that can offer greenhouse gas benefits over gasoline.
North Carolina State Univ. is part of a project team that is researching and developing new catalyst technology to produce the commercially important chemicals ethylene and propylene from natural gas. The project lead, Bio2Electric, LLC, dba EcoCatalytic Technologies, is collaborating with North Carolina State Univ., among other industry partners, to develop the new catalyst technologies.
Reform of energy subsidies in oil-exporting countries can reduce carbon emissions and add years to oil exports, according to a new paper from Rice Univ.’s Baker Institute for Public Policy. The paper reviews the record of energy-subsidy reforms and argues that big exporters should reduce energy demand by raising prices, and that this can be done without undermining legitimacy of governments that depend on subsidies for political support.
The stakes are incredibly high for the safety and compliance efforts of today’s oil and gas industry. Engineers and crews must be trained for increasingly complex processes and procedures used aboard drilling rigs and production platforms. The consequences of inadequate training during oil production can be disastrous to both operator crews and the environment.
High levels of the greenhouse gas methane were found above shale gas wells at a production point not thought to be an important emissions source, according to a study jointly led by Purdue and Cornell universities. The findings could have implications for the evaluation of the environmental impacts from natural gas production.
The Obama administration is driving ahead with a dramatic reduction in sulfur in gasoline and tailpipe emissions, declaring that cleaner air will save thousands of lives per year at little cost to consumers. Public health groups and automakers cheered the new rules.
A new study led by the Joint Institute for Strategic Energy Analysis says that the total impact of switching to natural gas depends heavily on leakage of methane during the natural gas life cycle, and suggests that more can be done to reduce methane emissions and to improve measurement tools which help inform policy choices.
The first thorough comparison of evidence for natural gas system leaks confirms that organizations including the Environmental Protection Agency (EPA) have underestimated U.S. methane emissions generally, as well as those from the natural gas industry specifically.
Methane, a key greenhouse gas, has more than doubled in volume in Earth's atmosphere since 1750. Its increase is believed to be a leading contributor to climate change. But where is the methane coming from? Research by a California Institute of Technology atmospheric chemist suggests that losses of natural gas—our "cleanest" fossil fuel—into the atmosphere may be a larger source than previously recognized.
Oil and gas remain primary power sources for both personal and industrial use worldwide. Extraction of these fuel resources from underground reservoirs involves complex geomechanical processes, and can result in subsidence of the ground over a reservoir. Since this occurrence can have an impact on the environment and affect the operability of extraction equipment, it needs to be accurately predicted and kept within safe limits.
If you are like millions of Americans and own a broad stock index fund, you own parts of Exxon Mobil, Peabody Energy and other companies that earn money selling oil, coal and other fossil fuels. For some, that's great. Fossil fuels give us light, keep us warm, help grow our food, deliver our products and jet us around the planet. Some companies are stable and profitable and offer consistent dividends that pad retirement accounts nicely.
The diesel-burning locomotive, the workhorse of American railroads since World War II, will soon begin burning natural gas—a potentially historic shift that could cut fuel costs, reduce pollution and strengthen the advantage railroads hold over trucks in long-haul shipping. Rail companies want to take advantage of booming natural gas production that has cut the price of the fuel by as much as 50%.
In an effort to put to good use natural gas (methane) that might otherwise become pollution, Lawrence Livermore National Laboratory is collaborating with start-up company Calysta Energy on a new technology to convert natural gas to liquid fuel. The process involves taking natural gas from oil and gas operations, and converting it to methanol that can be used as a fuel or converted to other useful chemicals.
The debate over exporting liquefied natural gas is intensifying as the Energy Dept. considers an array of applications to ship the fuel to Japan, India and other countries where prices are far higher than in the United States. Some large manufacturers that use natural gas say the department is moving too quickly to approve gas exports, pushing the U.S. into a "danger zone" that could raise prices and harm the economy.
The United States is spewing 50% more methane—a potent heat-trapping gas—than the federal government estimates, a new comprehensive scientific study says. Much of it is coming from just three states: Texas, Oklahoma and Kansas. It means methane, which doesn’t stay in the air long but is 21 times more potent at trapping heat than carbon dioxide, may be a bigger global warming issue than thought, scientists say.
Scientists at The Univ. of Texas at Austin have developed a new method to estimate gas production from hydraulically fractured wells in the Barnett Shale. The approach, which uses a simple physics theory called scaling, is intended to help the energy industry accurately identify low- and high-producing horizontal wells, as well as accurately predict how long it will take for gas reserves to deplete in the wells.
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.
