Abstract:

The deep ocean is a potential storage medium for anthropogenic carbon dioxide (CO2). However, there is strong opposition to ocean storage because of the potential acidification of large volumes of seawater around the discharge point. Furthermore, it is not clear whether international regulations would permit deep ocean discharge of anthropogenic CO2. This chapter reviews various proposals for oceanic CO2 injection designed to alleviate the acidification problem and to discharge the CO2 at sufficient depth so it will not rapidly re-emerge into the surface layer and back into the atmosphere. One proposal is described ...
