Gas Hydrate

Development of smart carbon sequestration and energy recovery system in marine gas hydrate deposit environment

This research investigates the geo-physicochemical factors in marine gas hydrate deposits and examines their micro-macro interaction on CH4 hydrate formation, CH4-CO2 hydrate replacement mechanism, and diffusion pattern change of fluids in the gas hydrate bearing sediments using computational methods and advanced analytical-monitoring system. Based on this information, this research aims to provide core knowledge for implementing smart CO2 storage and CH4 recovery system which can safely store CO2 as a form of hydrate and efficiently recover CH4 energy simultaneously in marine gas hydrate deposit.

• Characterization of geo-physicochemical factors and investigation of fundamental properties (formation and dissociation) of gas hydrates in deep ocean environment

• Molecular dynamics simulation and quantum calculation for the understanding of microscopic reaction mechanism of CO2 storage and CH4 recovery process

• Development of in-situ/on-line monitoring system for the understanding of macroscopic reaction mechanism of CO2storage and CH4 recovery process
