In connection with the global warming of climate in the Arctic zone (both on dry land and in the sea shelf) began the processes of decomposition of the permafrost, accompanied by isolation into the atmosphere of carbon dioxide and methane.The enormous deposits of methane hydrates on the bottom of the Laptev Sea, Eastern Siberian and Chukchi Sea, sea of Beaufort (depth not more than 50 m) began to separate methane into entire the increasing quantity.Freely separating from sea methanehydrates methane - this is the new alternative source of natural working medium with the extracted reserves into tens of trillions of cubometers of gas, which at present in no way is used. For putting out such a methane will be required neither seismic survey works nor reconnaissance boring nor enormous obtaining sea platforms. Expenditures for the production of the underwater, fully automated collectors of methane, their installation to the shoal (at the depths not more than 50 m), the padding on the bottom of the sea of gas pipe for pumping of gas to the coast station, the building and the maintenance coast gas station and power station, which works on the obtained gas, will be the basic expenditures with this method of putting out the gas. Power station is necessary for the guarantee with the electric power of all technological process of this method of putting out the gas.The natural conditions of the Laptev Sea and of the East Siberian Sea enhance to that proposed by the authors of the technology of the output of methane (small depth, the small fluctuations of sea level, the absence of strong flows, etc); therefore development and introduction of this technology can be executed only in 3-5 years. With the high degree of probability it is possible to assume that in this time the intensity of the isolation of methane even more will grow under the action of global warming and the proposed technology will undergo considerable development for the purpose of the gasification of the populated areas on eastern- Arctic shelf of Russia.
