Karunarathne et al. (2024): Review on CO2 removal from ocean with an emphasis on direct ocean capture (DOC) technologies

Sumudu Karunarathne, Sara Andrenacci, Andres Carranza-Abaid, Chameera Jayarathna, Michel Maelum, Ragnhild Skagestad, Hans Aksel Haugen IN: Separation and Purification Technology, https://doi.org/10.1016/j.seppur.2024.128598

Recent developments focus on maturing promising Carbon Dioxide Removal (CDR) technologies that remove and permanently store CO2. This article specifically examines a subset of CDR technologies referred to as ocean-based negative emission technologies (ONETs). The technologies under review involve modifications to seawater chemistry aimed at maximizing the ocean’s potential as a CO2 sink. Specifically, electrochemical ocean capture (EOC) and ocean alkalinity enhancement (OAE) are discussed.
