Storage of Liquid Carbon Dioxide in Deep-sea Sediment Layer:
Site Proposal in Japan
Summary
Suitable sites for the storage of liquid CO2 in the deep-sea sediment layer in Japan were examined on the premise of using a pipeline laid on the seafloor toward the offshore CCS storage site, including from the pressin facility to the wellhead on the seafloor.
There are eleven suitable storage sites identified within 100 km from the land. For each site, a storage capacity of one to three billion tons or more can be expected.
