Ocean alkalinity enhancement (OAE) could help absorb more CO2 without harming marine life, based on recent tests.

By Sean Mowbray Ocean-based carbon dioxide removal technology is ramping up, with startups and existing companies racing to ...

"Using its purchasing power to accelerate the most promising climate solutions." Microsoft announces unprecedented deal to ...

One solution is to accelerate and enhance the ocean's natural uptake of CO2 by increasing its alkalinity. Ocean Alkalinity Enhancement (OAE) mimics the natural process of rock weathering by adding ...

Ocean Alkalinity Enhancement (OAE) mimics the natural process of rock weathering by adding ground rock, or its dissolution products, directly to the seawater. So far, little is known about the ...

The ocean naturally absorbs a quarter to a third of man-made CO 2 emissions, but this process also leads to the acidification of seawater. By increasing the alkalinity of seawater through the ...

Our electrochemical ocean alkalinity enhancement method has the potential to be one of the largest scale and lowest cost approaches to removing excess CO2, while reducing ocean acidity.

The study adopted an approach with moderate perturbations to seawater chemistry: CO₂-equilibrated Ocean Alkalinity Enhancement. With this approach, the alkalised water that has already absorbed ...

Broadly speaking, mCDR is divided into two methods with some overlap: ocean alkalinity enhancement (OAE) and direct ocean capture (DOC), also known as direct ocean removal. OAE electrochemically ...
