Su et al. (2023): Direct Air Capture of CO2 through Carbonate Alkalinity Generated by Phytoplankton Nitrate Assimilation
Jing Su, Hui Teng, Xiang Wan, Jainchao Zhang & Cong-Qiang Liu IN: Int. J. Environ. Res. Public Health 20(1), 550; https://doi.org/10.3390/ijerph20010550
Here the authors report an ocean alkalinity-based CO2 sequestration scheme, taking advantage of proton consumption during nitrate assimilation by marine photosynthetic microbes, and the ensuing enhancement of seawater CO2 absorption.
