Company Wants to Turn Carbon Pollution into Baking Soda
The company's SkyMine project, in San Antonio, Texas, uses a three-step process that pumps the fumes from burning coal into water that is heated and fed through a filter that isolates hydrogen, chlorine and sodium hydroxide. That sodium hydroxide, also known as caustic soda, is then combined with the carbon dioxide also produced by the burning coal. When this new mixture is filtered, it produces sodium bicarbonate, or baking soda.
The project is still in the early testing phase, but by processing the pollutants to produce industrial chemicals that it can then sell, Skyonic believes it can make carbon capture a commercially viable way of combating global warming. [From: CNET]
