Meanwhile, Shell is preparing to anchor the world's largest floating offshore structure oe  the Prelude Floating Liquefied Natural gas facility oe  off Australia's northwest coast in 2014.
and will produce the natural gas equivalent of 100,000 barrels of oil per day. While few groups could afford to build a floating city capable of weathering such storms
And what is Shell going to do with Prelude once all the natural gas runs out? Â The infrastructure for a marine community will be waiting to be used.
At the same time that the scientific community is finding evidence that methane is being undercounted the newly released draft version of the U s. EPA's national greenhouse-gas emission inventory presents data showing that methane emissions from natural gas
The new draft inventory also revised downward estimates for past years because of new information about reduced emission well completions (the process that gets natural gas to start flowing) and other voluntary mitigation steps received from companies.
This treatment of methane emissions from natural gas is difficult to reconcile with the new Science study by Adam Brandt of Stanford university
The EPA greenhouse gas inventory uses data from bottom up studies to develop emission factors for different components of the entire natural gas system from production (extraction from the ground) to processing transmission and distribution.
These emission factors are part of an attempt to calculate representative quantities of pollution released with each of the activities that make up the natural gas system.
The emission factor is multiplied by the number of well completions of each type to estimate their contribution to total emissions from the natural gas system.
A limitation of the bottom-up studies upon which the EPA inventory relies is a requirement that researchers obtain access to natural-gas operations.
and natural gas by 2035. Since taking office, electricity production from wind and solar sources has doubled already more than in the United states. We are boosting our use of cleaner fuels,
America has regained its position as the world s leading producer of natural gas. My administration is promoting the safe,
responsible development of America s near 100-year supply of natural gas that will help support more than 600,000 jobs.
but instead to facilitate responsible use of all energy sources from oil and coal and natural gas, to nuclear and hydropower and biofuels, to wind and Solar energy development, economic growth,
The decline is in part a result of the economic slowdown and a shift in electricity production from coal to natural gas,
encouraging the shift towards natural gas. Other rules could target the oil and gas industry by limiting emissions from refineries and drilling sites.
Americans Want More Energy From Wind Solar Gasno fewer than two in three Americans want the U s. to put more emphasis on producing domestic energy using solar power (76%)wind (71%)and natural gas (65%.
%Least favored is coal with about one in three Americans wanting to prioritize its domestic production. www. gallup. com/poll/161519/americans-emphasis-solar-wind-natural-gas. aspxlistenup regardless of the tone

beera discovery at Rice university aims to make vehicles that run on compressed natural gas more practical. It might also prolong the shelf life of bottled beer and soda.
The combination could be a boon for an auto industry under pressure to market consumer cars that use cheaper natural gas.
This becomes increasingly important as automakers think about powering cars with natural gas. Metal tanks that can handle natural gas under pressure are often much heavier than the automakers would like.
He said the material could help to solve longstanding problems in food packaging too. Remember when you were a kid you'd get a balloon
The commercial market for hydrogen gas is now around $100 billion for hydrogen produced from natural gas
and natural gas account for about half of the CO2 that humans add to the atmosphere each year; these power plants are prime candidates for new technology that captures CO2 before it goes up in smoke.
That technology--a two-phase chemical process--has been used for decades to remove naturally occurring CO2 from natural gas.
The liquid amine captures CO2 and drains away while the purified natural gas bubbles out the top of the column.
The CO2 that comes out of the ground with natural gas is under high pressure while the CO2 at power plants is said not Hirasaki There's also a greater volume of CO2 per unit mass at a power plant than at a natural gas well.
For these reasons and others the amine process must be engineered re if it is to be cost-effective for CO2 capture at power plants.
and compressed natural gas vehicles such as the Honda civic Natural gas. Although driving costs per mile will be lower especially for vehicles powered by natural gas
or electricity the high initial purchase cost is likely to be a significant barrier to widespread consumer acceptance the report says.
Natural gas vehicles were considered but their greenhouse gas emissions are too high for the 2050 goal.
and other industries fueled by coal natural gas and oil. Capturing and sequestering those emissions could play a significant role in curbing global warming.
and in fact require natural gas to operate. Following the 2012 negative-emissions workshop GCEP issued an international request for proposals to develop net-negative carbon emissions technologies.
#Global natural gas boom alone wont slow climate changea 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 appearing today in Nature.
Because natural gas emits half the carbon dioxide of coal many people hoped the recent natural gas boom could help slow climate change
--and according to government analyses natural gas did contribute partially to a decline in U s. carbon dioxide emissions between 2007 and 2012.
But in the long run according to this study a global abundance of inexpensive natural gas would compete with all energy sources--not just higher-emitting coal
Inexpensive natural gas would also accelerate economic growth and expand overall energy use. The effect is that abundant natural gas alone will do little to slow climate change said lead author Haewon Mcjeon an economist at the Department of energy's Pacific Northwest National Laboratory.
Global deployment of advanced natural gas production technology could double or triple the global natural gas production by 2050
but greenhouse gas emissions will continue to grow in the absence of climate policies that promote lower carbon energy sources.
Thinking Globallyrecent advances in gas production technology based on horizontal drilling and hydraulic fracturing--also known as fracking--have led to bountiful low-cost natural gas.
Because gas emits far less carbon dioxide than coal some researchers have linked the natural gas boom to recent reductions in greenhouse gas emissions in the United states
. But could these advanced technologies also have an impact on emissions beyond North america and decades into the future?
and policy experts led by PNNL's Joint Global Change Research Institute gathered at a workshop in Cambridge Maryland in April 2013 to consider the long-term impact of an expansion of the current natural gas boom on the rest of the world.
and projected what the world would be like in 2050 with and without a global natural gas boom.
Swapping out coal for natural gas in a simple model would cut greenhouse gas emissions a result many people expected to see.
â#¢Natural gas replacing coal would reduce carbon emissions. But due to its lower cost natural gas would also replace some low-carbon energy such as renewable or nuclear energy.
Overall changes result in a smaller reduction than expected due to natural gas replacing these other low-carbon sources.
In a sense natural gas would become a larger slice of the energy pie. â#¢Abundant less expensive natural gas would lower energy prices across the board leading people to use more energy overall.
In addition inexpensive energy stimulates the economy which also increases overall energy use. Consequently the entire energy pie gets bigger. â#¢The main component of natural gas methane is a more potent greenhouse gas than carbon dioxide.
During production and distribution some methane inevitably escapes into the atmosphere. The researchers considered both high and low estimates for this so-called fugitive methane.
The combined effect of the three the scientists found is that the global energy system could experience unprecedented changes in the growth of natural gas production
Recyclable material absorbs 82 percent of its weight in carbon dioxiderice University scientists have created an Earth-friendly way to separate carbon dioxide from natural gas at wellheads.
Natural gas is the cleanest fossil fuel. Development of cost-effective means to separate carbon dioxide during the production process will improve this advantage over other fossil fuels
Traditionally carbon dioxide has been removed from natural gas to meet pipelines'specifications. The Tour lab with assistance from the National Institute of Standards and Technology (NIST) produced the patented material that pulls only carbon dioxide molecules from flowing natural gas
and polymerizes them while under pressure naturally provided by the well. When the pressure is released the carbon dioxide spontaneously depolymerizes
or use it for enhanced oil recovery to further the release of oil and natural gas. Or they can package
Methane ethane and propane molecules that make up natural gas may try to stick to the carbon but the growing polymer chains simply push them off he said.
The research offers new perspective on evolutionary biology microbiology and the production of natural gas and may shed light on climate change agriculture and human health.
Methane is the main component of natural gas and a potent greenhouse gas. This innovative work demonstrates the importance of a new global regulatory system in methanogens said William Whitman a professor of microbiology at the University of Georgia who is familiar with the study
The same process allows natural gas production from agricultural residues a renewable resource. Methanogens also play an important role in agriculture
New york and Pennsylvania are sitting on an enormous reserve of natural gas, the Marcellus Shale. You're looking for real urgency and drive.
take natural gas. In New york and Pennsylvania, we're sitting on one of the greatest shale gas reserves in the world.
Today, we want the natural gas because it meets the needs of global climate change, but it taints our water supply.
Like stopping leaks from natural gas pipelines. Not only does this make economic sense this makes climate sense.
No one wants to lose their natural gas, it a product. And methane is worse than CO2 on the list of greenhouse gasses.
And they are doing natural gas research. And better biofuels research, like re-engineering plants, so they do a better job of turning sunlight into fuels than current plants do.
