STARTUPS BEGIN GEOENGINEERING THE SEA

Summary from the TLDR newsletter

Captura is a company that plans to electrochemically strip carbon dioxide out of the ocean, store or use it, then return the water to the sea, where it will naturally absorb more carbon dioxide from the air. It will start pumping as much of the Pacific ocean as it can in a few months at Hawaii's Keāhole Point. Besides Captura, there are dozens of similar field trials and pilot projects that will start scaling up their facilities in 2025.
