Summary:CO sub(2) ocean sequestration, which is thought to be a promising measure to mitigate global warming, can be classified mainly into the dissolution and the storage methods. On the evaluation of these measures, CO sub(2) hydrate plays an important role, because CO sub(2) becomes a hydrate in the ocean deeper than 500 m (North Pacific Ocean)[approx]900 m (North Atlantic Ocean). The solubility of CO sub(2) shows a dual nature (solid and liquid solubilities) in the hydrate forming region. Two types of unexpected hydrate membrane strength just below the dissociation temperature and in a CO sub(2) saturated solution, and the rebuilding process under stressed conditions greatly influence the above two CO sub(2) ocean sequestration methods.
