This data-file models the economics of capturing CO2 from exhaust flues using the amine process, in order to calculate what CO2 price is necessary to earn a passable IRR. This is one of three components of a CCS project, alongside CO2 transport and CO2 sequestration.
Input assumptions can be flexed in cells H5:35 of the model, in order to stress test the sensitivity to gas prices, energy efficiency, amine costs, water costs, capex, G&A and fiscal conditions. Our own base case estimates are informed by five tabs of cost data and technical papers. While we have also developed a rough scenario for deploying CCS on a large ship.
CO2 costs are extremely sensitive to CO2 concentrations, rising exponentially if it is necessary to capture CO2 from more diffuse sources. The typical CO2 concentrations of different exhaust streams is tabulated in another of our data-files, here.
