xperts believe it is possible to store carbon dioxide (CO2) deep beneath the earth’s surface. This process is generally known as carbon sequestration. The CO2 is injected into permeable substances and kept underground by a layer of impermeable rocks. At depths beginning around 2,600 feet, carbon dioxide will liquefy and can densely stored. The illustration to the right shows the different geological formations ideal for carbon sequestration.
- Depleted oil and gas reserves
- Enhanced Oil Recovery
- Saline Aquifers
- Unmineable Coal Seams
- Enhanced Coal Bed Methane Recovery
- Basalts, Oil Shales, Cavities
