CO2 Sequestration by Dave Kahn Submitted to Dr. Thomas Edgar - ChE 379

Costs • carbon dioxide capture would add 1.5 cents/kWh • carbon dioxide is already being separated via power station flue gases for applications in the food industry
Technical Description http://www.co2captureproject.org/technologies/tech_img2.gif
Leakage The Frio Brine Project source: www.greencarcongress.com
Leakage • To date, no leakage has been detected • However, the study has shown that after the carbon dioxide is sequestered, the chemical properties of the water and the dissolved inorganic carbon change • Changes include: • sharp drops in pH • pronounced increases in alkalinity • significant shifts in the isotopic compositions • Also, it has shown that the CO2 can degrade carbonate substances in the rock
Conclusions • The Earth is warming! • CO2 capture for sequestration would add ~15% to untaxed energy bill • Sequestration can increase oil recovery efficiency by 10-15% • It has not yet been shown to leak • It has however shown potential for leakage channeling • Recommendations – Much more research
