Go Read More Posts On FuturePundit April 17, 2003 Natural Gas Made Into Pellet Hydrates For Easier Transportation Technology review has an interesting article on the work of Japanese researchers to convert natural gas into a solid form to make it easier to transport from small remote fields that would otherwise be too expensive to operate. Japanese researchers Hajime Kanda and Yasuhara Nakajima at Mitsui Engineering and Shipbuilding in Tokyo think they’ve found a solution with the aid of hydrates, solid crystals in which natural gas—composed chiefly of methane—is caged inside of water molecules. If the article is correct then currently most of the natural gas in the world is not exploitable because the fields are too small and can't justify the cost of building pipelines to transport the natural gas from them to market. If these Japanese researchers succeed then natural gas could become a much larger percentage of total fossil fuel use. It is worth having a look at world natural gas reserves . The world total known reserves of oil is 1212.811 billion barrels and for natural gas it is 5,501.424 trillion cubic feet. Saudi Arabia has the biggest oil reserves at 261.800 billion barrels or about 21% of world oil reserves. But Russia has 1680 trillion cubic feet of natural gas or over 30% of world natural gas. Russia has only 60 billion barrels of oil reserves while Saudi Arabia has only 224.7 trillion cubic feet of natural gas.

Data on Natural Gas Hydrates
Approved by the CODATA 23 rd General Assembly in Montréal 2002
Renewal approved by the CODATA General Assembly, Berlin 2004
The CODATA Task Group on Data on Natural Gas Hydrates was re-approved at the 24th CODATA General Assembly in Berlin Enormous deposits of methane hydrate exist at many worldwide locations in the ocean floor and in the permafrost. The amount of hydrated energy is twice that of all the other fossil fuel energy sources combined. The documentation and understanding of this unconventional gas deposit, is essential to resolve major societal questions such as energy reserve and recovery, climate change, global carbon budget, seafloor hazard stability, gas transportation, and flow assurance in oil and gas pipelines. In 2000 CODATA established a hydrate task group, which was renewed in 2002. In addition, an ICSU grant enabled much of the group activity. The challenge of the group was to deal with a subject whose essence involved many disciplines, such as chemistry, physics, geology, geochemistry, geophysics, chemical engineering, and petroleum engineering. The initial coordination of these disciplines posed a major challenge to the organization of our work. The objective of the current Task Group is the development of the concept of a comprehensive information system of all aspects of natural gas hydrates. We will formulate the requirements on the type of data needed in the system and their quality. This work will enable the users to address problems of natural origin and transformation of gas hydrates from nature.

USGS Fact Sheet "Methane trapped in marine sediments as a hydrate represents such an immense carbon reservoir that it must be considered a dominant factor in estimating unconventional energy resources; the role of methane as a 'greenhouse' gas also must be carefully assessed."
- Dr. William Dillon, U.S. Geological Survey
Hydrates store immense amounts of methane, with major implications for energy resources and climate, but the natural controls on hydrates and their impacts on the environment are very poorly understood.
Gas hydrates occur abundantly in nature, both in Arctic regions and in marine sediments. Gas hydrate is a crystalline solid consisting of gas molecules, usually methane, each surrounded by a cage of water molecules. It looks very much like water ice. Methane hydrate is stable in ocean floor sediments at water depths greater than 300 meters, and where it occurs, it is known to cement loose sediments in a surface layer several hundred meters thick.
The worldwide amounts of carbon bound in gas hydrates is conservatively estimated to total twice the amount of carbon to be found in all known fossil fuels on Earth.

Icy substance called gas hydrate might be source of clean-burning fuel Monday, December 13, 1999 By Byron Spice, Science Editor, Post-Gazette Flammable ice sounds like a bad oxymoron, something that belongs on a list with "tight slacks," "fresh frozen," "simply confusing," "Microsoft Works" and the ever popular "military intelligence." But flammable ice is a fair description of the planet's most abundant, if least recognized, form of fossil energy. Called methane hydrate, or gas hydrate, it's an ice-like substance composed of methane the main constituent of natural gas trapped inside cages of water molecules. It forms under pressure, with deposits found underneath permafrost in Arctic regions and beneath deep ocean floors. When extracted and placed in normal atmospheric pressure, chunks of the stuff pop and fizzle as highly concentrated methane escapes. It can even be set aflame. Gas hydrate ceased to be this Mr. Wizard-ish curiosity in 1995, when the U.S. Geological Survey assessed U.S. gas hydrate resources. The study concluded that hydrate deposits entrapped between 112,000 trillion cubic feet and 676,000 trillion cubic feet of methane. The estimate was refined in 1997 to a more conservative 200,000 trillion cubic feet, but it still dwarfed the 1,400 trillion cubic feet in the nation's conventional gas reserves. Worldwide, the figures are even more staggering 400 million trillion cubic feet, compared with 5,000 trillion feet in known gas reserves. Even oil and coal reserves are no match.

Fossil fuel revolution begins
The methane could be liquefied at sea and transported by tanker
By BBC News Online's Damian Carrington
The first step in a new era of global energy production is being taken, with a Japanese attempt to recover vast reserves of frozen methane gas from under the ocean floor.
End of the energy crisis?
Professor Richard Selley The drilling project began on Friday and is the first commercial offshore attempt but it is fraught with danger. Accidental releases of vast volumes of the buried gas have in the past led to the destruction of oil platforms in the Caspian Sea. These releases are also a possible explanation for the mysterious disappearances of ships. "It's horrifically dangerous," said Professor Richard Selley, a gas hydrate expert at the Royal School of Mines, Imperial College, London. "If they drill in with a conventional drill ship and they hit the stuff and destabilise it, all the gas comes bubbling up and the ship will sink. "The Japanese are the brave souls who are drilling this first commercial test offshore," added Professor Selley. "It may be very easy to avoid the risk of a catastrophic blowout but this is the first to test it."

Home Overview of Natural Gas Background History ... Focus on LNG Unconventional Natural Gas Resources Historically, conventional natural gas deposits have been the most practical, and easiest, deposits to mine. However, as technology and geological knowledge advances, unconventional natural gas deposits are beginning to make up an increasingly larger percent of the supply picture. So what exactly is unconventional gas? A precise answer to that question is hard to find. What was unconventional yesterday, may through some technological advance, or ingenious new process, become conventional tomorrow. In the broadest sense, unconventional natural gas is gas that is more difficult, and less economically sound, to extract, usually because the technology to reach it has not been developed fully, or is too expensive. For example, prior to 1978, natural gas that had been discovered buried deep underground in the Anadarko basin was virtually untouched. It simply wasn't economical, or possible, to extract this natural gas. It was unconventional natural gas. However, deregulation of the area (and particularly the passage of the

The Top Ten Technologies: #2 Hydrogen Economy Enablers
One of the most significant global trends arriving in the near future is a shift away from fossil fuels and towards hydrogen. The term, "hydrogen economy " refers to a global economy powered by hydrogen, not oil. The hydrogen economy is important for the advancement of humanity for several reasons. First off, the oil economy is fraught with problems: Pollution: burning fossil fuels generates alarming levels of pollution that affect every living organism on the planet. We pollute our cities the worst, contributing to tens of millions of premature deaths each year due to the disease-causing effects of inhaled by-products from combustion engines, coal plants and other machines powered by fossil fuels. Fossil fuels also contribute to global pollution through oils spills, oil extraction, oil refining, and other processes. Global warming: although this topic is aggressively debated, there is growing consensus that the burning of fossil fuels contributes strongly to global warming. The true impact of this warming is often lost on the general public, because it seems so remote from modern life. The natural consequences of global warming are quite severe: rising oceans , disappearing coastlines, mass extinction of ocean life, severe and unpredictable

Introduction - Man and Hydrocarbon
Petroleum refers to any naturally occurring hydrocarbon found beneath the Earth's surface. It forms from when organic carbon is trapped in sediments and buried. Humans for millennia have exploited hydrocarbons. For example the Babylonians used the solid form of hydrocarbon known as asphalt to pave roads and seal boats and the Egyptians used tar to embalm mummies. The Greeks used condensate, which is a clear volatile form of oil, as the main ingredient in their "Secret Weapon of Byzantium" also know as "Greek Fire" which they used to decimate Turkish navies for five centuries. Around 500 BC the Chinese used natural gas to light their imperial palaces. The Ancient Greek Navy decimated the Turks with a secret weapon known as Greek Fire. The chief ingredient was oil condensate which burns on water. Later in the 14th century, the Greeks had forgotten about their secret weapon and were conquered by the Turkish Empire wielding their own form of burning hydrocarbon.

EMD: Down to the Crossroad
The energy industry is at a crossroads petroleum is in the rearview mirror and a methane-based economy is squarely ahead. What will this fundamental change in the energy mix mean for public policy, the environment and earth sciences? Many of the answers to those questions rest with the U.S. Geological Survey. "I think our role over the next 20 years will be identifying, assessing and determining the availability of the world's remaining energy resources," said Patrick Leahy, USGS associate director of geology. Leahy, who said his agency's job is to "develop scenarios ... and try to understand any environmental and economic affects that accompany those resources in terms of their development," will be the keynote speaker at the Energy Minerals Division luncheon Wednesday, April 21, at the Dallas Convention Center. His talk is titled "The USGS Role in Preparing for the Energy Mix of the Future."

The Thomas Gold experiment of deep drilling in Norway was inconclusive on the subject of whether methane comes from the core. More conclusive is the composition of the gas hydrates collected at the bottom of the ocean as a "glacier" 1-2 km thick covering MOST OF THE DEEP OCEAN (1/2 the earth's surface). There is more energy in this gas than all other fossil fuels put together, past present and future. We have experts here at the Colorado School of Mines who educate me on these topics, Typically the bottom half of the methane in the hydrate comes from below - thermogenic in origin. The other half is generated from dead material falling from above that composts to organic methane (and Someday these hydrates may be a major source of energy for Humans, but they won't be easy to extract at a depth of .4 -4 km.

Gas hydrate deposit detection and instability
Chemosynthetic biological communities are evidence of the presence of reduced, chemical-rich fluids at the seafloor. When the fluids are generated at ambient temperatures, as opposed to high temperatures such as at hydrothermal vents, they are said to be "cold seeps". Cold seeps have now been found in diverse locations, such as on canyon walls, on active continental margins, from limestone escarpments, and above hydrocarbon deposits. Acoustic surveys also provide evidence of cold seeps, and of layers of gas hydrates (carbon-dioxide, methane, and other hydrocarbon gases frozen into an icy slush at high pressure and low temperature) within the sedimentary pile. Gas hydrates are large reservoirs of methane, which is a fossil fuel and green-house gas. Methane is also the compound required by methane oxidizing microbes whose by-product feeds the hydrogen-sulfide oxidizing microbial symbionts that feed the cold-seep biota. Instabilities of the gas hydrate reservoirs may be a consequence of slumping and earthquakes on a local scale, and of increasing ocean temperatures on a global scale.
