Hi this forum was misinformed lol
the exploitation of the deposit will be done with a storage of C0²
that will liquefy the methane hydrates on the spot

For the financiers who are interested in the project, the revenues of this sector are all the more interesting that the CO2 balance sheet of the operation is negative, ie it is necessary to inject more CO2 than n 'will emit recovered methane, a carbon sequestration technology that can generate GHG emission credits with high economic value.
On paper it looks pretty good ... (less bad actually )
To recover this solidified methane, the researchers have developed a method for passing it into the gaseous phase at the bottom of the water. They use CO2, also in the gas phase, which would come, for example, from GHG emissions from a thermal power station. This carbon dioxide releases the methane without igniting it and it solidifies itself on the seabed where it will remain imprisoned at least 1000 years, explains Perter Herzig, that is to say the time that will be necessary for seawater to warm up to 400 meters deep by more than two or three, which would be possible in case of constant and severe global warming.
It is that 1000 years ... we already have feedback on this release !? Slow, fast, explosive, by massive destabilization of the methane hydrate deposit, by dissolution / acidification of the sea ... any kouak!
It's like the nuke, we want to imprison a time bomb without knowing when it will trigger. Always according to the good principle to enrich some irresponsible now but especially to leave me.de future generations ...

For the moment it is still coal since we know how to exploit it on a large scale.
Carbohydrates are attractive, but we have not yet found sustainable ways to exploit them.
In my opinion a little patience before announcing it, sometimes it would turn like shale gas.
Maybe they'll change one day, that's all we can do.

Hi Christophe
would you be so misinformed?
(I thought you were Engineer ensai?)
Methane hydrate - Wikipedia
fr.wikipedia.org/wiki/Hydrate_de_méthane
The reserves of methane hydrate are so great that many oil companies are interested.
What more is needed ??
In fact it's neither one nor the other
it's all the seas, when we'll be able to do deuterium fusion

Hi Flytox
You all know that!

You're waiting for Santa ???? dying of laughter
Or would you have a solution ??

Not much, just to say that these hydrates are not going in the right direction ... In the sense, the race to appropriate more and more energy and toast it all the time. First we extract and once the environment is all destroyed we say: "It may be necessary to do something" ..... once the deposit is exhausted and the irresponsible profiteers are force-fed.You're waiting for Santa ???? dying of laughter
Yes, the same as it is.Or would you have a solution ??
Sorry but No, unfortunately, and the time of awareness of our dirty species and it may be already too late?

Potential methane reservoirs Beneath Antarctica

Once thought to be devoid of life, the ice-covered parts of Antarctica are now known to be a reservoir of metabolically active microbial cells and organic carbon1. The potential for methanogenic archaea to support the degradation of organic carbon to methane beneath the ice, however, has not yet been evaluated. Large sedimentary basins containing marine sequences up to 14 kilometers thick2 and an estimated 21,000 petagrams (1 Pg equals 1015 g) of organic carbon are buried beneath the Antarctic Ice Sheet. No data exist for rates of methanogenesis in sub-Antarctic marine sediments. Here we present experimental data from other subglacial environments that demonstrate the potential for overridden organic matter beneath glacial systems to produce methane. We also numerically simulate the accumulation of methane in Antarctic sedimentary basins using an established one-dimensional hydrate model3 and show that pressure / temperature conditions favor methane hydrate formation down to sediment depths of about 300 meters in West Antarctica and 700 meters in East Antarctica. Our results demonstrate the potential for methane hydrate accumulation in Antarctic sedimentary basins, where the total inventory depends on rates of organic carbon degradation and conditions at the ice-sheet bed. We calculate that the sub-Antarctic hydrate inventory could be of the same order of magnitude as that of recent estimates made for Arctic permafrost. Our findings suggest that the Antarctic Ice Sheet may be a neglected but important component of the global methane budget, with the potential to act as a positive feedback on climate warming during ice-sheet wastage.
