"Geological Storage as a Carbon Mitigation Option" was the title of Celia's 2008 Darcy Lecture. Anthropogenic emissions of CO2 have increased atmospheric concentration of CO2 by about 35 percent during the past 200 years. The current concentration, at about 385 ppm, represents the highest CO2 concentration in the last 500,000 years. Projected future emissions will lead to doubling of preindustrial CO2 concentration within the next 50 years. If this relentless increase of atmospheric CO2 is to be reduced, or reversed, technological solutions must be implemented on a massive scale. While many options are being considered, one attractive approach is carbon capture and storage, or CCS.
