We conducted a meta-study of CO2 capture processes, examining nearly 100 techno-economic analyses published in the recent open literature. Normally, it is difficult to compare one study to another because each study uses its own set of assumptions, such as plant scale, geography, market parameters, and inconsistent definitions of key metrics such as the cost of CO2 avoided (CCA). In this work, we present normalized versions of these studies using a consistent basis of comparison, such as net power delivered, base year of operation, pipeline CO2 pressure, currency, country of construction, and so on. In so doing, we are able to draw meaningful conclusions and direct comparisons between different classes of CO2 capture technology. The technologies considered include coal and gas-based processes using capture strategies including solvent-based post-combustion carbon capture, gasification-based strategies, membrane-based approaches, oxyfuel combustion, chemical looping combustion, calcium looping, and solid oxide fuel cell (SOFC) processes. We then compute key metrics for each of these studies such as the cost of CO2 avoided on a consistent basis across all studies in the literature, which allow us to identify the technologies which are the most promising for CO2 emissions avoidance on the macro-level. Some key conclusions include that SOFC technology is clearly the most promising in terms of both CCA and actual emissions avoided, with chemical looping combustion and oxyfuels as promising alternatives that are more commercially mature. Membrane-based technologies as a class in general show very little promise for coal, and even the most optimistic systems using hypothetical membranes are unable to compete against even the poorest performing SOFC, oxyfuel, and chemical looping processes presented in the literature. In addition, the study found that for North American markets, the conditions are such that natural gas is so cheap such that there is little incentive to use coal at all, except with SOFC systems. Solvent-based technologies for natural gas combined cycle systems, although not necessarily as efficient as more advanced systems like oxyfuels, are quite natural choices for near-term CO2 mitigation purely based on cost.
