The techno-economics of alternative CO2 transport systems and their application in the Canadian oil sands industry

摘要: Abstract The rise in GHG emissions from the oil sands industry has prompted government and to seek ways reduce its CO 2 output. CCS is currently leading option Alberta. A key making it viable a system that allows multiple emitters gather, capture, transport their best sinks, efficiently economically. are located Northern Geological formations suitable for storage exist South-West region, ∼400 km sources. Implementing will necessitate transporting roughly 30 megatonnes of sinks. One sinks underground aquifer Redwater Reef near Ft. Saskatchewan, with an estimated preliminary capacity one gigatonne , or 37 years sands, at 2007 rates. In this study, we compare two schemes operations by capturing and: (1) supercritical state (2) solution Redwater, regenerating solvent on-site storing Reef. fugitive Case 1 consistently higher than those 2. This due former’s electricity demands fact associated energy regeneration not captured. more susceptible cost fluctuations 2, but latter changes price fuel. Although CAPEX similar both, benefits economies scale 1; OPEX 3.5% higher. avoidance costs lower on gross basis (111 vs. 114 $/tonne ) net (327 851 ).
