The team is made up of scientists from the Lawrence Livermore National Laboratory, Harvard University and the University of Illinois at Urbana-Champaign. They developed a new carbon capture media which is made up of core-shell microcapsules, whose highly permeable polymer shell contains sodium carbonate solution, which reacts with and absorbs carbon dioxide. Sodium carbonate makes up a large part of baking soda, according to an article on cemag.com.

Carbon dioxide is free to pass through the shell, but the liquid is held inside. Microcapsules of this kind are used in the controlled delivery and release of pharmaceuticals and food flavoring, for example, but have never been used to capture carbon dioxide. The science behind the idea could eventu...
