• CO_2 hydrate sequestration in sub-seabed sediments has been proposed as a novel option for greenhouse gas control, where liquid CO_2 is injected in seabed sediments, reacts with pore water and forms hydrates. The hydrate-filled sediments (hydrate sealing) are expected to serve as artificial cap rock, enabling a large volume liquid CO_2 to be stored in the underlying sediments. One of major concerns is whether hydrate formation can retard CO2 flow and prevent it from floating to the seabed. Model tests have been conducted to observe CO_2 flow behavior during hydrate formation when injected, at a constant rate, into an initially water-saturated porous glass model. The results shown that hydrate formation can efficiently retard the CO2 flow.
