Energy Ice Kvenvolden, who estimates the amount of gas hydrates on Earth the amount of all otherfossil fuels combined US could more than double its natural resource supply http://www.acfnewsource.org/environment/energy_ice.html
Extractions: Printer-friendly version E-mail this story to a friend Scientists find vast supplies of alternative energy trapped in ice deep in the earth. Oil prices recently reached a 30-year high, prompting former President Clinton to tap our national reserves and reviving the debate about drilling in places like the Arctic National Wildlife Refuge. But some scientists believe the most promising source of energy in the future is not petroleum, but natural gas locked in ice. Inside a particular type of ice crystals called hydrates are trapped molecules of methane, the key constituent of natural gas. Hydrates are crystal structures similar to ice; inside which molecules of gas are held in a natural state. If the methane can be extracted from its "cage," it could be burned just like natural gas a much cleaner form of fuel than coal or petroleum. As USGS Menlo Park researcher Keith Kvenvolden explains, methane hydrates are what you get when you have water and methane together under certain conditions. It is sometimes called "flammable ice" because it is a highly combustible solid material that only exists at extremely low temperatures and high pressures. But because it can only exist in such conditions, researching it can be extremely difficult. Hydrate deposits are known to exist deep beneath the ocean floor and closer to the Earth's surface in permafrost Arctic regions. The size of the deposits around the world, from the Gulf of Mexico to Siberia, is enormous, says Kvenvolden, who estimates the amount of gas hydrates on Earth to be more than twice the amount of all other fossil fuels combined. According to the Department of Energy, if only one percent of the existing deposits could be exploited for domestic consumption, the U.S. could more than double its natural resource supply.

Researchers are on a quest to understand the microorganisms that produce gas hydrates trapped in the ocean floor. The hydrates may be a boon to an energy-hungry world, but their release could trigger catastrophic global warming. "There is a huge amount of hydrated natural gas around ocean margins," said Mark Delwiche, a microbiologist at the Idaho National Engineering and Environmental Laboratory. "If there was some clever way of extracting it from the ground it would be a tremendous resource." Gas hydrates are methane gas molecules trapped in lattices of ice. They are the products of microorganisms that feed on organic matter that has been washed into the ocean or has died in it. Since methane gas burns more efficiently and cleanly than any other fossil fuel and researchers estimate the volume of extractable methane gas to be more than twice the amount of known reserves of all other fossil fuels, it is an attractive resource.

Extractions: Climate Class Methane: The 'Other' Greenhouse Gas So much attention is paid to carbon dioxide as part of the greenhouse effect that people tend to overlook another critically important gas in manmade greenhouse warming methane. Methane, or CH4 (four hydrogen atoms and one carbon atom), is the main ingredient in the natural gas our home stoves use. The concentration of methane in the atmosphere is minute about 1.7 parts per million, by volume (ppmv). Thats much lower than the concentration of carbon dioxide (in 1998, just over 360 ppmv) but methane is far more efficient than CO2 at trapping heat. The Intergovernmental Panel on Climate Change estimates methanes global warming potential as 21 times more than CO2 on a pound-for-pound basis over 100 years. Methane in the atmosphere has increased even faster than carbon dioxide during the industrial age to more than double its pre-industrial concentration. Current levels are the highest ever observed, even compared against air bubbles trapped in 420,000-year-old ice. The IPCC estimated in 1990 that methane accounted for some 15 percent of the manmade increase in radiative forcing during the previous decade (compared with 55 percent for CO2). Thats the bad news. Theres some good news about methane, too. Its lifetime in the atmosphere is far shorter than that of carbon dioxide hardly more than a decade, as compared with 50-200 years for carbon dioxide. That means any reductions in human emissions will have a quicker payoff in slowing global warming.
Coal Atlas Estimates of the amount of carbon bound in gas hydrates are almost twice theamount of carbon found in all known fossil fuels on Earth; hence, hydrates http://www.emdaapg.org/Gas Hydrates.htm
Extractions: GAS HYDRATES Gas hydrates are crystalline solids that consist of gas molecules, usually methane, surrounded by water molecules. The gas molecules are densely packed in a crystalline structure so that hydrate deposits can store vast quantities of methane. Estimates of the amount of carbon bound in gas hydrates are almost twice the amount of carbon found in all known fossil fuels on Earth; hence, hydrates represent a dominant unconventional energy resource. Though these hydrates are abundant worldwide, particularly in Arctic regions and in marine sediments, there is much to learn about how they form, evolve, interact with surrounding sediments, and affect environmental conditions when extracted. EMD members are active in chairing technical sessions, presenting talks and posters, and promoting gas hydrate research and development efforts. - Laura Wray EMD GAS HYDRATE COMMITTEE STATUS REPORT November 15, 2000 The following report has been prepared for the November 18-19, 2000, EMD Business Meeting.

Extractions: Energy Plan Our insatiable need for energy will never be met by conventional fossil fuels Our continued reliance on fossil fuels will be a wasted effort and a colossal expense, that in 50 years or so will leave us with choking clouds of pollution and insufficient energy needs. It's time we pull our heads out of the sand and wake up to reality! The only power source that can provide clean air and meet our near- term future needs is nuclear. The nuclear power industry has an amazing safety record. The only thing unsafe about nuclear power reactors is the Government's inability to protect them! But that can be easily remedied. The French have had a long-term commitment to nuclear power. They currently get 78% of their power needs from nuclear, as opposed to 16% for the U.S., and they have an even better record of safety than us. Solar power as a renewable resource will always be hampered by earth's atmosphere and low output solar cells will take up enormous space. However Professor David Criswell of Houston's Institute for Space Systems Operations, detailed a plan at the annual meeting of the American Geophysical Union , to build huge solar farms on the Moon and microwave the power back to Earth. This would require a 50 billion dollar commitment and would break even in about five years. You say it sounds like science fiction! I say I've seen a great deal of science-fiction become science-fact in my lifetime.

Extractions: HOUSE ACTION PLANNED July 23, 1998 Washington, D.C. The United States Senate has passed legislation authored by United States Senator Daniel K. Akaka (D - Hawaii) to promote research and development of methane hydrates as an energy resource. The Methane Hydrate Research and Development Act (S. 1418) would establish a research and development program at the Department of Energy to assess and develop methane hydrates as an energy source. The House Committee on Science has scheduled a hearing on the Akaka bill for Tuesday, July 28, 1998. Methane hydrate is a methane-bearing, ice-like substance. It is stable at moderately high pressures and low temperatures and contains large quantities of methane. One unit volume of methane hydrate contains over 160 volumes of methane at standard temperature and pressure. Methane hydrates are found in deep ocean sediments and northern permafrost. An enormous amount of methane is sequestered in gas hydrates. Scientists estimate there is twice as much carbon in methane hydrate than all other fossil fuels, including coal. By any measure, this is a staggering resource. Natural gas will grow in importance as demand for clean burning fuel increases. Also, as we move to reduce greenhouse gas emissions, natural gas will become an even more strategic fuel source because its emissions contain significantly less carbon dioxide. Methane hydrates hold a near endless supply of natural gas.

Honours The Hydrate Group at the Department of Petroleum Engineering, Heriot-Watt University has been awarded a grant from the Scottish Higher Education Funding Council (SHEFC) for the establishment of a Centre for Gas Hydrate Research. The Centre should be seen as a natural outcome of the increased interest in hydrates, especially in areas such as environmental impact, a potential source of energy, and transportation of gas from remote fields to consumers, together with the track record that the Hydrate Group has built up over the last fourteen years. The Centre for Gas Hydrate Research will be a focus for research covering a range of topics from avoiding gas hydrate problems in subsea pipelines and processing facilities, to positive applications of gas hydrate technology in the oil and gas industry. An integrated experimental and computer simulation approach will be adopted to provide the much needed experimental data and prediction tools for reducing the risks of gas hydrates and benefiting from their positive applications.

AKAKA INTRODUCES METHANE HYDRATES BILL of carbon found in all other fossil fuels on Earth trillion cubic feet (tcf) of conventionalnatural gas. profound questions about methane hydrates, Akaka noted http://www.senate.gov/~akaka/releases/99/01/199901281824.html
Extractions: January 28, 1999 Washington, D.C. - United States Senator Daniel K. Akaka (D - Hawaii) introduced legislation to promote research and development of methane hydrates as an energy resource. The Methane Hydrate Research and Development Act of 1999 would establish a research and development program at the Department of Energy to assess and develop methane hydrates as an energy source. The legislation is identical to an Akaka-sponsored measure that passed the Senate in the 105th Congress. Senators Trent Lott (R-MS), Mary Landrieu (D-LA), Bob Graham (D-FL), and Larry Craig (R-ID) are co-sponsors of the bill. Methane hydrates are rigid, ice-like solids of water surrounding a gas molecule. They remain solid at high pressure and low temperature. Such conditions are found in Arctic permafrost and in deep sea sediments. Methane hydrate has tremendous gas storage capacity: one volume of methane hydrate will expand to more than 160 volumes of methane under normal temperature and pressure conditions. Methane hydrates are stable at moderately high pressures and low temperatures and contain large quantities of methane. An enormous amount of methane is sequestered in gas hydrates. Worldwide estimates range from 100,000 trillion cubic feet to 270 million trillion cubic feet. Estimates on U.S. deposits are between 2,700 trillion to seven million trillion cubic feet. "We are only beginning to quantify and characterize methane hydrate resources. Our understanding of these deposits, their location, and their potential as a commercial resource is surprisingly limited," said Akaka. "Fundamental research on methane hydrates is urgently needed to develop our long-term energy supply, improve oil and gas extraction, and further the science of global climate change.

Extractions: VARIOUS OPTIONS TO MEET ENERGY REQUIREMENTS The world is only a few years away from the depletion of its fossil fuel stock. The need of the hour is the commercialization of renewable and non-conventional sources of energy besides sustained oil conservation. The article examines the Indian possibilities for such new initiatives. THE NEED TO CONSERVE PETROLEUM PRODUCTS Today every country draws its energy needs from a variety of sources, which can broadly be categorized as commercial and noncommercial. The commercial include fossil fuels (Coal, oil, and natural gas), hydroelectric power and nuclear power, while the noncommercial sources include wood, animal wastes and agriculture wastes. Per capita energy consumption in developing countries remains low despite rapid advances. The world noncommercial fuels contribute approximately 60% of the total primary energy consumption. The subject of alternate energy sources are not only the energy for tomorrow but for today also. Heavy and constant use of fossil fuels in the developed world and the irrational use of the firewood in the developing countries has resulted in environmental degradation. The basic goals of a country are to achieve energy self-sufficiency and preservation of environment.
