•Comprehensive review of carbon capture facilities based on TRL was conducted.•CO2 capture technologies were compared regarding TRLs and techno-economic prospects.•Pre- and post-combustion carbon capture are more reliable than other options.•Pre-combustion has lower operating and higher capital cost compared to post-combustion.•Review helps select suitable capture option considering various aspects. Carbon capture options, including pre/post-combustion, oxyfuel, and chemical looping combustion, have been noticeably exploited in recent years at various technological readiness levels (TRL). Although review studies that address carbon capture strategies are widely available, a comprehensive review based on the TRL of the most recent carbon capture facilities operating worldwide has yet to be conducted. In this review study, in addition to summarizing the key features of the widely-used conventional physicochemical solvents, a brief discussion on the novel, commercialized enzyme-accelerated solvents (e.g., enzyme-catalyzed aqueous salt solutions) is provided. Moreover, the physical absorption technologies for CO₂ capture (i.e., Selexol, Rectosil, Purisol, Flour, and Moyrphysorb) are addressed. A systematic survey was followed to compare CO₂ capture techniques by presenting the respective advantages and disadvantages as well as technical and economic aspects. Finally, conclusions are drawn based on the maturity level of capture technologies. Accordingly, promising novel carbon mitigation routes based on the most recent progress in the carbon capture field are proposed. This review can shed useful light on the selection and adoption of optimal technologies for CO₂ capture, considering the characteristics of the flue gas source, the energy penalty, and economic considerations, together with current technological advancements.
