Abstract:
Warm water is pumped up by a pump from an underground aquifer present 1000 to 1500 m below the seabed, geothermal energy is caused to flow through a permeable layer below a methane hydrate layer, a dissociation boundary surface of an un-dissociated area of the methane hydrate layer is dissociated to generate methane gas, the methane gas is led into a production well from peripheral areas and through a gas inlet screen and caused to rise so that the methane gas is collected on the sea.
