Fakhraee et al. (2023): A biogeochemical model of mineral-based ocean alkalinity enhancement: impacts on the biological pump and ocean carbon uptake
Mojtaba Fakhraee, Zijian Li, Noah J Planavsky, Christopher T Reinhard IN: Environ. Res. Lett. 18, 044047, https://doi.org/10.1088/1748-9326/acc9d4
The authors used a series of biogeochemical models to evaluate the gross CDR potential and environmental impacts of ocean alkalinity enhancement using solid mineral feedstocks. The authors find that natural alkalinity sources—basalt and olivine—lead to very low CDR efficiency while strongly perturbing marine food quality and fecal pellet production by marine zooplankton.
