Aleta et al. (2023): Direct Ocean Capture: The Emergence of Electrochemical Processes for Oceanic Carbon Removal

Prince Aleta, Abdelrahman Refaie, Mohsen Afshari, Ahmad Hassan, Mohammad (Mim) Rahimi IN: Energy Environ. Sci.,

The authors investigated recent advancements and challenges in electrochemical direct ocean capture (eDOC) of carbon dioxide (CO2), a negative emissions technology for oceanic carbon removal. The authors analyzed different eDOC strategies, focusing on pH swing as the primary mechanism for ocean dissolved inorganic carbon removal, and examines techno-economic challenges, such as achieving industrially preferred current densities and reducing overall costs.
