METHANE HYDRATES

 Very interesting Cabe.  Several months ago I had an opportunity to work with several professors at Mississippi State regarding hydrates.  Several facts were presented as follows:

 Large amounts of methane, naturally frozen in this form, have been discovered in both permafrost formations and sea beds under the ocean's floor.  Methane hydrates are believed to form by migration of gas from significant depths along geological faults, followed by precipitation or crystallization, upon contact with rising gas streams of cold sea water.   About 6.4 trillion (that is, 6.4x1012) tons of methane lie at the bottom of the oceans in the form of clathrate hydrate.  Each kilogram of fully occupied hydrate (actually only about 96% occupancy is found) holds about 187 liters of methane (at atmospheric pressure).  

 One significant fact, ice-core methane clathrate records represent a primary source of data for global warming research, along with oxygen and carbon dioxide.   This is one reason why there is research data available on the huge quantities of entrapped methane gas.   Mr.  M.E. Benesh first proposed using this technique as a method of storing natural gas as early as 1942. At that time, the methodology of doing so was not available, now it very well may be as demonstrated by Mississippi State.  

My client was asking the question as to whether or not this method would be a viable approach to transporting Natural Gas; i.e. methane for commercial use.  The approach was very much cost-prohibitive at that time.

@etmax, Attempting to control by taxation will bring about levels of government coruption not previously known. Those who are able make their living in business or industry, those who are not able make their living working forthe government. And having that kind of people deciding who will pay what amount of tax would esily be enough to start a revolution that would be quite ugly. That kind of tax is very much the sort of thing that destroys any belief in government honesty, it is just plain destructive.

But an aggressive approach to planting can lead to an effective way of removing the carbon dioxide without having the government goons trying to run our lives. For an example, just look at the TSA, which has ruined flying as an enjoyable experience and not done much to keep the bad guys off the planes. It has been demonstrated repeatedly that assorted weapons can slide right past them. So the solution is not more regulation and government interference, it is in working to capture that carbon in plants. Cheap, easy, and energy efficient.

Extraction Of Natural Gas By Methane Hydrate

Thanks Cabe for such an informative post . This is really amaziing that Japan is extracting natural gas from methane hydrate deposits in the seabed. However every technology has its pros and cons on one place with the help of this technology there can be increase in natural gas production on huge ratio however on the other hand it is very costly procedure , Seconldy drilling the seabed is not easy and is not as simple as considered there can be various damages that can lead to enviornmental issues and because of which government of different countries can retaliate as well.

I'm not sure we have the arable land available to plant enough trees to do this only with absorbtion by that means, we have a 7e9 world population and heading towards 1e10 in a few years. We currently burn oil at a ridiculous rate because it's so cheap yet we also depend on that same oil for the manufacture of fertilisers to grow food, make medicines and plastics. Some of this can be replaced by alternative chemistries, but not all. So why wouldn't you want a mechanism that prevents this valuable resource being wasted on fire? Then think of helium, at our current rate of use we are likely to run out in the next 20-50 years. What do we do? we fill party balloons with it for a 1-2 day use. Helium is essential in medicine and science, there are no current replacements which will result in people dying. A $1 tax on helium in party balloons would stop this use so there can be no money made and therefore no corruption, Just as a $1 tax on throw away plastic bags can't cause corruption because no one would buy a $1 bag for one time use, and the supermarkets certainly wouldn't give them away. So no sale and no corruption :-) Mostly what I'm saying is that planting trees is only a small part of the solution, and that reduction has to be a large part of it until CO2 levels start coming down.

Bobjengr,

If we could use the hydrates properly, would you see it as the answer to our energy worries?

Efficiently extracting is another story.
