Abstract: A systematic evaluation of the economics incurred by the introduction of absorption and membrane capture technologies to a power plant is presented in this work. Cost diagrams were constructed to estimate the cost of electricity, CO2 capture, and avoidance cost of CO2 capture-integrated power plant, based on the key performance indicator of the capture technology, which allows fair and objective techno-economic comparison of different capture technologies. This schematic correlation of capture cost can be very useful for the assessment of technologies with low technology readiness level, because all the technical details to quantify the performance of capture systems are not readily available in the early stage of technology development. In addition, a detailed breakdown of key costing elements between the power plant and the capture plant are presented, which helps users to not only understand the technical advances or drawbacks of capture technologies considered, but also to gain conceptual insights for the direction of research and development. These graphical correlations of techno-economics of capture processes were validated with a wide range of assessment results, and extremely good agreement was observed in the range of −0.4% to −1.2% for the error.
