One way to slow the release of the greenhouse gas carbon dioxide into the atmosphere is carbon capture sequestration, or ccs. It involves catching CO2 at power plants, compressing it, and injecting it into cavities deep underground. University of Miami doctoral student Caitlin Augustin has developed a computer model to study ccs safety and efficacy.

CAITLIN AUGUSTIN (University of Miami):

So I put in what is the structural geology, what are the materials that this reservoir is built on, how much are we going to inject over a period of time, do we know the seismic activity there? And I can use that to build a site-specific risk assessment.

HIRSHON:

The goal of the research is to provide the information needed to draft laws in the use of CCS to insure that it’s safe and effective. I’m Bob Hirshon, for AAAS, the science society.
