Such technologies – including SeaCURE – work by electrochemically removing dissolved inorganic carbon from seawater, which can then be stored. It is thought that ocean or marine carbon dioxide removal – in addition to radical carbon emissions reductions – represents an important component in efforts to mitigate global warming. The SeaCURE pilot plant has allowed us to begin to understand DOCCS technology in a limited, small-scale and controlled way. The new study has significant implications for the emerging marine carbon removal industry and climate policy. “The ocean’s vast carbon storage capacity makes marine carbon dioxide removal techniques like DOCCS potentially very exciting.
