Gas hydrate undersea generation method, gas hydrate generation apparatus, and carbon dioxide underwater storage system

摘要

PPROBLEM TO BE SOLVED: To provide a highly practically useful technology which can generate a large amount of COSB2/SBhydrate with a simple constitution and store it in the sea for isolating carbon dioxide causing global warming, in the ocean. PSOLUTION: In an underwater storage system of carbon dioxide, carbon dioxide is introduced into a gas hydrate generator 11 installed at a prescribed depth in the sea, carbon dioxide is brought into contact with seawater while regulating the water depth position of the gas hydrate generator 11 by buoyancy due to gas or the like stored in the generator, COSB2/SBhydrate 50 is generated by using seawater pressure, and the generated COSB2/SBhydrate 50 is settled and stored in storage parts 81, 82 on the bottom of sea.
