ABSTRACT

CO2 clathrate hydrate can form in sediments in a seabed, resulting in an artificial impermeable overlaying bed. A large quantity of liquid CO2 can be sequestrated in the layer. In this study, successful observation of CO2 sequestration into model sediments using glass beads with clathrate hydrate was achieved. The stability and sealing properties of CO2 hydrate layer were experimentally investigated for environmental assessment.
