As human activity and climate change increase the amount of carbon dioxide in the ocean, harming coral reefs and marine life, researchers have designed a new technology using aqueous sodium hydroxide and sodium carbonate to remove carbon dioxide from ocean water, helping reverse acidification and reduce global warming.

“It took years to pull this off experimentally,” said Katherine Hornbostel, assistant professor of mechanical engineering and materials science at the University of Pittsburgh’s Swanson School of Engineering. “So it was super rewarding to see when the experimental results finally matched our model[s].”
