Storage of CO2 at low temperature as liquid or solid gas hydrate Application in the French and Spanish EEZ in North-East Atlantic
International audience Another storage option (the so-called “deep offshore” option) is the trapping of CO2 in deep-sea sediments at lower temperature and higher pressure than the standard options, the onshore and offshore storage options. In those conditions, CO2 may be liquid and denser than seawa...

International audience Another storage option (the so-called “deep offshore” option) is the trapping of CO2 in deep-sea sediments at lower temperature and higher pressure than the standard options, the onshore and offshore storage options.
