🧽 Turning the oceans into a giant sponge is the project imagined by Gaurav Sant, professor of civil and environmental engineering at the University of California at Los Angeles (UCLA).
He advocates using the ocean as a giant carbon sponge.
⚡️ The project uses electrolysis, which splits water into hydrogen and oxygen and thus would lock up the CO2 in mineral salts, carbonates. The latter would then end up in the ocean, where they would remain stable.
💧 The treated water would be released into the ocean, ready to absorb more carbon. In addition, the method produces hydrogen that could be used to reduce the overall cost of the process.
👨💼 According to the project leader, Carbon dioxide levels are 150 times more concentrated in seawater than in the air, meaning extracting carbon from the ocean is more efficient than other carbon removal methods.
👉 If all goes well, an operating facility using this technology could be running within the next five to seven years.
