Harnessing Ocean Alkalinity Enhancement (OAE) for CO₂ Decomposition and Renewable Energy Production : The AODOP Innovation Towards Net-Zero Emissions 2060

As the concentration of carbon dioxide (CO₂) in atmosphere increases, carbon emissions entering the oceans have become a significant concern in context climate change studies as stated by the Intergovernmental Panel on Climate Change (IPCC) report, 30 ...

Ocean liming effect on a North Atlantic microbial community: changes in composition and rates

Frontiers in Marine Science
The ongoing rise in atmospheric CO2 levels and the consequent global warming make it increasingly difficult to maintain the global temperature within the 1.5 - 2°C target set by the Paris Agreement. Therefore, strategies to remove carbon dioxide from the

Evaluating rainbowing for ocean alkalinity enhancement [PDF]

Ocean Alkalinity Enhancement (OAE) is a technique proposed to address ocean acidification and global warming. This study examines rainbowing (i.e. water jets pumped into the air from ships) for the slaked lime slurry distribution.

Assessing the effectiveness of ocean alkalinity enhancement on carbon sequestration and ocean acidification

FACETS
As atmospheric carbon dioxide (CO2) levels continue to rise, increasing attention is focussed mitigation techniques that could enhance the natural draw down of CO2. One such mitigative intervention is ocean alkalinity enhancement (OAE).

Marine carbon dioxide removal by alkalinization should no longer be overlooked

Environmental Research Letters
To achieve the Paris climate target, deep emissions reductions have to be complemented with carbon dioxide removal (CDR). However, a portfolio of CDR options is necessary to reduce risks and potential negative side effects.

KOSMOS 2022 Bergen mesocosm study on ocean alkalinity enhancement: phytoplankton metabolic rates

Ocean alkalinity enhancement (OAE) is a marine carbon dioxide removal (mCDR) with the potential to remove atmospheric CO2 and increase the ocean's buffering capacity. Thus, it may aid in mitigating global warming and ocean acidification. Depending on the

Assessing the impact of CO2-equilibrated ocean alkalinity enhancement on microbial metabolic rates in an oligotrophic system

Ocean alkalinity enhancement (OAE) is a negative emissions technology (NET) that shows significant potential for climate change mitigation. By increasing the bicarbonate ion concentration in ocean water, OAE could enhance long-term carbon storage and ...
