Risk assessment of enhanced geological storage of CO2 using gas hydrates

Research output: Contribution to journalArticlepeer-review


The framework of risk assessment system for Carbon Dioxide Capture and Storage (CCS) is proposed, especially for enhanced recovery of gas, oil, and gas hydrates. Based on the protocol proposed by the EU, the framework of enhanced CCS has been modified to improve the functions of geological-based performance assessment. Simulation results of CO2 migration and the estimation of the leakage of CO2 in pathways are presented. The promotion of methane gas hydrates would be one method of CO2 storage in the geological structure of marine sediments. The original method of CO2-CH4 substitution in the production of gas hydrates is presented. Air-con.
