They have, the Japanese, a magnificent boat the "Chikyu" (land), the first in the world, designed well before March 11, 2001, cable to drill 7 km below the seabed, special for raising this methane from the seabed stored in huge quantities for millions of years, enough to multiply by 10 the CO2 and to melt the whole of the Antarctic and raise the seas by 70m, like, spontaneously, 56million years ago, the warmer earth of 10 to 15 ° C more, the poles having our temperate climate at 15 ° C !!

All the big cities of the world would be under water almost !!!


There is no peak oil or fuels !!!

The vessel, called "Chikyu" which means Earth, will dig about 260 meters below the seabed and set up four wells.

One of the four wells will be used for methane hydrate production tests and the remaining three will be used to monitor possible changes in the environment, such as temperatures.

In March 2011, the Chikyu drill ship was damaged by the earthquake and tsunami in Japan. It was repaired at Shingū, Wakayama dock and returned for service in June 2011.

Chikyū (ち き ゅ う?) Is a Japanese scientific drilling ship built for the Integrated Ocean Drilling Program (IODP). The vessel is designed to ultimately drill seven kilometers beneath the seabed, where the Earth's crust is much thinner, and into the Earth's mantle, deeper than any other hole drilled in the ocean thus far.


Japan, US to test methane hydrate reserves

Japan's semi-governmental energy body and a major US energy company have sealed a deal to test for methane hydrate reserves in the northern part of the US state of Alaska.

Methane hydrate is a type of natural gas formed from methane and water.

Japan Oil, Gas and Metals National Corporation, or JOGMEC, made an agreement with the US energy firm, ConocoPhillips, to carry out testing from January next year.

The 2 entities will back a project to dig a well up to 1,000 meters that will gauge the amount of gas contained in the area.

Methane hydrate reserves have also been identified in sea beds off Japan's coast. Some experts say the amount is potentially so great it could meet Japan's gas requirements for one-hundred years.

Japan is seeking ways to efficiently extract these natural gas molecules. It's hoped the joint experiments with the US firm will pave the way.

It's not huge, but in these articles they find formation of methane by reduction of CO2 by volcanic heat (2/3 of methane) which proves that part of the methane in depth is produced without photosynthesis by this reduction at great depth of CO2 in the earth with internal heat and volcanic earth !!

We therefore have 2/3 of abiotic methane in this lake !!!

http://www.3tamis.org/templates/DOSSIER ... tudes.html

So abiotic fuels are well produced and observed, which multiplies the methane reserves underground and also abiotic oil.

We are not going to see a peak of fossil and abiotic fuels !!!
We are going to melt all of the Antarctic before seeing this peak !!!


Research has shown that CO2 is produced in the lake by volcanic activity, while CH4 is produced by two processes - by reducing CO2 as well as - by the oxidation of organic matter by bacterial activities. The first process contributes to 2/3 and the second to 1/3 of the total amount of methane formed in the lake (Tietze et al., 1980)

these methane hydrate are interesting

they are unstable and risk being released in the event of heating, it is not stupid to exploit them usefully rather than to let them get lost

In the permafrost yes ... at the bottom of the oceans I am not sure that global warming has a real impact ... except indirectly with the disruption of the circulation of large ocean currents ...

The ocean floor is very slow because with enormous thermal inertia, it therefore takes thousands of years.
Since the enormous warming of the last 15000 years, it has gone from below freezing to 4 ° C, however, according to scientific studies !!!

Is that so? I thought the ocean floor is and always had been at 4 ° C, the point of maximum density of water ...

It seems to have started well indeed.
And, a technique is being studied: CO2 is injected into the deposits, this immediately takes the place of methane and all that remains is to recover it.
Suddenly, this will trap the CO2 produced by human activity and reduce pollution in the atmosphere.

the exploitation of the deposit will be done with a storage of C0²
that will liquefy the methane hydrates on the spot



The largest source of primary energy: Methane hydrates

'' '' There are about 20 billion tons of natural gas, 40 billion tons or gigatonnes (Gt) of oil, 540 Gt of coal, but 3000 Gt of methane hydrates! '' '' '


@Hic

well if the forum know.
There is even this thread.

The extraction of methane is accompanied by the injection of CO2 which will then be transformed into methane (reduction by heat of magma). An indirect way to exploit geothermal energy ...
