Geologic Sequestration of CO2 in Deep, Unmineable Coalbeds: An Integrated Researdh and Commercial-Scale Field Demonstration Project
Aapg Bulletin(2008)
Abstract
Coalseams represent an attractive opportunity for near-term sequestration of large volumes of anthropogenic CO2 at low net costs. There are several reasons for this: • Coals have the ability to physically adsorb large volumes of CO2 in a highly concentrated state. • Coals are frequently located near large point sources of CO2 emissions, specifically power generation plants. • The injection of CO2 into coalseams actually enhances the commercial methane recovery process. • The recovery of coalbed methane is enhanced when the injected gas contains nitrogen, a major constituent of power plant flue gas.
