Ocean alkalinity enhancement in an estuary

Frontiers in Climate
A high-resolution numerical ocean model is used to assess ocean alkalinity enhancement (OAE) in the San Francisco Bay (SFB) estuary. A novel tracer-based approach is introduced to simulate alkalinity release and the subsequent CO2 ingassing. The model is

Social considerations and best practices to apply to engaging publics on ocean alkalinity enhancement [PDF]

, 2023
Ocean alkalinity enhancement (OAE) seeks to increase the alkalinity of seawater for carbon dioxide removal (CDR). Following numerous propositions to trial, test, or upscale OAE for CDR, multiple social considerations have begun to be identified.

A numerical assessment of ocean alkalinity enhancement efficiency on a river-dominated continental shelf—a case study in the northern Gulf of Mexico

Environmental Research Letters
A robust high-resolution coupled hydrodynamic-biogeochemical model was applied to the northern Gulf of Mexico to assess the efficiency of river- and ocean-sourced ocean alkalinity enhancement (OAE).

Interactions between ocean alkalinity enhancement and phytoplankton in an Earth system model [PDF]

Biogeosciences
The functioning and efficiency of ocean alkalinity enhancement (OAE) as a CO2 removal strategy is well investigated in model studies, but risks for the ecosystem are presently not considered in models.

Economic Assessment of Ocean Alkalinity Enhancement Through Electrodialysis: The Role of Carbon Credits in Comparing Solar Energy and Thermal Waste Technologies

Advanced Sustainable Systems, Volume 10, Issue 6, June 2026.
This study evaluates the economic feasibility of an Ocean Alkalinity Enhancement (OAE) plant with an annual CO2 removal capacity of 878 tonnes. The project is profitable only under scenarios with high carbon credit prices, while medium and low‐price scenarios yield a negative net present value.

On the Efficiency and Durability of Purposefully Sinking Seaweed Biomass as a Marine Carbon Dioxide Removal Strategy

Earth's Future, Volume 14, Issue 5, May 2026.
Abstract Large‐scale farming and purposeful sinking of seaweed has been suggested as a marine Carbon Dioxide Removal (mCDR) strategy. Farmed seaweed uptakes dissolved inorganic carbon (DIC) from the mixed layer, resulting in a CO2 deficit that causes an influx of atmospheric CO2 into the surface ocean.

KOSMOS 2021 Gran Canaria mesocosm study on ocean alkalinity enhancement: phytoplankton metabolic rates [PDF]

Ocean Alkalinity Enhancement (OAE) could augment long-term carbon storage and mitigate ocean acidification by increasing the bicarbonate ion concentration in ocean water. However, the side effects and/or potential co-benefits of OAE on natural planktonic

Report on the detailed life cycle analysis results of the two case studies: ocean alkalinity enhancement potential of Spain [PDF]

, 2023
A common challenge in many ocean-based negative emissions technologies (NETs) is the difficulty of developing new global industries and supply chains, which could be necessary for their much needed rapid and large-scale deployment.
