“…Few environmental assessments have been published with primary focus being on coal with post-combustion and/or pre-combustion capture (Benetto et al, 2004;Doctor et al, 1993;Khoo and Tan, 2006;Koornneef et al, 2008;Korre et al, 2009;Rao and Rubin, 2002). Few studies have also considered natural gas CCS options (Audus and Freund, 1997;Hertwich et al, 2008;Odeh and Cockerill, 2008;Singh et al, 2010;Summerfield et al, 1995;Waku et al, 1995;Lombardi, 2003). However, many of these studies have only focused on the capture process, CO 2 emissions, and global warming.…”
