A group of former Google, SolarCity and Tesla executives in April snagged $20 million in what is being called the largest ocean-based carbon removal investment to date.
Ebb Carbon, is betting electrochemistry can help speed up the ocean’s natural ability to sequester atmospheric carbon dioxide. It hopes to set up shop near desalination plants, seaside power plants, aquaculture operations, salt producers and other coastal industrial facilities, where its system can "intercept," treat and capture salty water flowing through wastewater pipes. That water is treated using low-carbon electricity to produce hydrochloric acid and sodium hydroxide. The acid is diverted from the ocean, but the other solution is returned, where it enhances the ocean's natural ability to capture sequester carbon dioxide.
