Abstract

The technical literature and much of the public policy dialogue about national or basin scale geologic carbon dioxide storage capacity estimates emphasizes the short comings in the methodologies employed in these studies because of their need to employ simplifying assumptions over large volumes of deep geologic structures. This short communication seeks to bring forward a better understanding of the role of these macroscale assessments and their value. In doing so, the author hopes that the there will be a more balanced discussion of macroscale geologic carbon dioxide storage assessments as compliments to the detailed site specific assessments needed to site any given carbon dioxide capture and storage facility.
