Underground Carbon Dioxide Sequestration: Frequently Asked Questions. January 21, 2009

摘要

This report answers frequently asked questions about the geologic sequestration of carbon dioxide (CO2). The questions are broadly representative of typical inquiries regarding the process and mechanics of storing CO2 underground, how much might be stored, and what might happen to CO2 once it is injected underground. Geologic sequestration is one step in a process termed carbon capture and sequestration, or CCS. Following capture and transportation, CO2 would be injected into geologic formations that have suitable volume, or pore space, to retain large quantities of the captured gas. Currently, the most promising reservoirs for storing CO2 are oil and gas fields, deep saline reservoirs, and unmineable coal seams.
