Marine carbon removal technology that turns carbon dioxide in seawater into 'stone' for permanent storage‎

A research team led by Professor Dong-Yeun Koh of the Department of Chemical and Biomolecular Engineering, in collaboration with Professor T. Alan Hatton's group at the Massachusetts Institute of Technology (MIT), developed an electrochemical dissolved ocean carbon removal (e-DOC) technology that converts carbon dioxide dissolved in seawater into calcium carbonate (CaCO₃), a stable mineral form that enables virtually permanent carbon storage.
