Abstract

The invention relates to a gas hydrate mined by adopting a low-temperature solid oxide fuel cell method and a device thereof. CH4 mined by using CO2 replacement is introduced into a low-temperature solid oxide fuel cell for generating electrochemical reaction, and then generates electric energy; and then the produced CO2 is introduced into a hydrate storage layer for replacing CH4 to ensure that the device continuously circularly operates. The invention has the advantages of not damaging stratum, realizing the zero emission of CO2, solving the problems of production, storage and transportation of the CO2 with large volume while obtaining the energy contained in the hydrate stratum, effectively lowering the investment of the device and the cost because the fuel cell is convenient to assemble and can be recycled, and reducing the cost because the gas hydrate can be mined by using the low-temperature solid oxide fuel cell method through using wide hydrocarbon fuel.

Description

technical field

[0001] The invention relates to a low-temperature solid oxide fuel cell method for exploiting natural gas hydrate and a device thereof, belonging to the field of natural gas exploitation. Background technique

[0002] Natural gas hydrate is a kind of energy with huge reserves. Gas hydrates widely exist in deep-sea formations and permanent ice zones around the world, and their total content is estimated to be 2 × 10 16 m 3 , the reserve of marine sedimentary gas hydrate is ( 1~5) ×10 15 m 3 , because of its huge reserves, high energy density, wide distribution, and large scale, it is considered to be the most ideal alternative energy source in the 21st century. The exploration, development and utilization of hydrates have become the focus of global competition, but with the past few hundred Over the years, atmospheric CO 2 The concentration rises from 280ppm to 370ppm, leading to a gradual rise in global temperature and serious damage to the earth's ec...
