El vídeo del enlace es una explicación sencilla e informativa de un procedimiento de captura muy sugerente conocido como Mejora de la alcalinidad del océano (#OAE), y que nos servirá además para entender el ciclo natural que manteniene la estabilidad del ph del océano a largo plazo.

A 3-year old animation explaining Ocean Alkalinity Enhancement in plain terms. Well done.

We are preparing a “Guide to Best Practices for Ocean Alkalinity Enhancement Research” (https://oae-best-practice.carbondioxide-removal.eu/project/).

The first chapter is now available for open review: “Assessing the technical aspects of OAE approaches”, in the new Copernicus journal State of the Planet.

Big thanks to Jean-Pierre Gattuso and Andreas Oschlies to initiate the community effort to write a Best Practices Guide for Ocean Alkalinity Enhancement Research as a form of ocean CO₂ removal (CDR).

Please comment and review! We need a joint effort to identify best practices in #OAE !

It is worth to closely follow the #OceanAlkalinityEnhancement case in St.Ives as it has potentially large implications, not only on start-ups, but also on #OAE research.
Some thoughts...

If we want to track the result of an ocean alkalinity enhancement (#OAE) for ocean CO₂ removal (#CDR), a tracer release followed by continuous survey for ~3 weeks is reasonable.

To do so from a suitable ship (day rate $50k/day) will cost $1 million for just 20 days of ship time.

The point is, this ain't gonna be cheap. People assume that we can just dump some rocks or some NaOH into the ocean and the job is finished. However, doing it right and having proper MRV will be expensive.
