New electrochemical technology could de-acidify the oceans—and even remove carbon dioxide in the process
For example, we estimate that the equivalent mass of roughly eight thousand Empire State buildings worth of alkaline substance would need to be added into the oceans each year starting by mid-century to meet IPCC emissions targets. Clearly, this technique cannot be the sole solution., the acidity of seawater is removed directly without the addition of other substances. This technology only requires seawater, electricity and specialized membranes.
BMED technology is limited in part by the specialized membranes that are commercially available. What's more, these membranes account for a significant portion of the capital cost and have short lifetimes as they are Alongside this, we must also identify optimal large-scale deployment locations where OAE can be safely and effectively implemented.
