(408e) Guidelines for Techno-Economic Assessment of Carbon Capture and Utilization Technologies
AIChE Annual Meeting
Tuesday, October 30, 2018 - 3:47pm to 4:04pm
However, economic advantages are not always guaranteed since CCU technologies face several challenges, for example high energy demands which often lead to increased operational costs. Many economic or financial analyses of identical technologies deviate in their results due to different methods, assumptions or use of data. To enable a fair and comprehensive decision making based on results of economic analyses of CCU technologies guidelines for systematic and standardized techno-economic assessment (TEA) of CCU technologies have been developed. TEA is a methodology framework to assess the technical and economic performance of a process, product or service.
Following the standard procedure for Life Cycle Assessment (LCA), the guidelines comprise of the following phases: goal and scope, economic and technical inventory data collection, TEA indicator calculation and the interpretation of results.4 The goal provides the framework for the overall study and CCU specific research, development and deployment questions, the scope defines what aspects are included and how the comparison of CCU technologies with conventional processes is being conducted, the inventory collects all relevant data which is required for the indicator calculation producing the TEA results. The interpretation phase simultaneously evaluates the results from other phases by analyzing the uncertainty and sensitivity. The goal and all interpreted results are summarized in the final reporting.
TEA results will be integrated with LCA results, since decision making often is dependent on economic as well as ecologic aspects of CCU technologies. In all phases, CCU specific challenges will be addressed and guidance how to address these challenges will be given. The application of the guidelines will be demonstrated with three case studies from different CCU fields: chemicals, fuels and minerals.
