Scientists Develop a way to Trace and Track CO2 Underground
Why underground? Well, consider that a lot of emissions come from power plants—coal plants and the like—so, scientists started investigating underground caverns, fissures and coal beds to find places where those emissions can be stored; thus reducing the amount of greenhouse gases in the atmosphere.
So, how do they find and track the carbon? They used colorless, non-toxic liquids called perfluorocarbon tracers. These tracers were used to fingerprint CO2 that was injected into a coal seam in New Mexico. By tracking the tracers, they were able to follow the movement of the CO2.
