CO2 Storage in Carboniferous Formations and Abandoned Coal Mines.

Abstract

The special report on Carbon dioxide Capture and Storage (CCS) under the auspices of the United Nations—Framework Convention on Climate Changes constitutes a milestone in the world, which needs to urgently develop strategies that take into account the control and reduce emissions of greenhouse gases (GHG). Among the various GHG, carbon dioxide (CO2) is the most abundant component, whose underground storage has been proven in low risk. This publication describe the present day conditions of CCS projects with particular emphasis in the description of the processes associate to the capture and transportation of CO2; the different types of solutions of underground storage of carbon; and the existing projects. Finally the storage in carboniferous formations is examined separately, since China has the major resources in coal in the world, as well as a large number of abandoned coal mines.
