This white paper presents a new set of guidelines developed to address important carbon capture and storage (CCS) cost issues in three areas. The first area of study tackles the establishment of improved guidelines for cost evaluation of advanced low-carbon technology (such as a new CO2 capture process or a novel power plant design). The second area of study focuses on CCS from non-power industries (such as cement plants, steel mills, refineries, and other industrial sources of CO2 emissions), which is a growing area of focus for CCS implementation. The final area addresses quality assurance and uncertainty evaluations of data and models used in CCS cost analysis.
