# Abstract: This spreadsheet model was produced as part of the CCS Capture Benchmark Refresh Study, and provides a techno-economic analysis of the performance of a state-of-the art CCGT with and without amine capture at 90% capture rate. The spreadsheet enables ‘what if’ calculations of costs for the following designs: CCGT with and without capture, at 100% and 40% load; CCGT with and without capture, with 38% and 18% exhaust gas recycle rates, at 100% and 40% load; CCGT with an independent capture plant, generating its own power and steam, at 100% load; CCGT with an independent capture plant, generating its own steam only, at 100% load CCGT with retrofitted capture plant, at 100% load. Outputs include capital costs, operating costs, cost of capture and levelised cost of electricity. The spreadsheet concentrates on power generation, capture and compression, but allows manual input of transport and storage costs to provide overall figures. These cases are covered in Benchmark Refresh reports D2.1 (refresh of CCGT benchmark and EGR) and D7.1 (Independent Capture Plant). It should be noted that the underlying capture plant designs were reviewed as part of the Independent Capture Plant work, so the results given by this spreadsheet for the earlier cases may not precisely match those presented in Report D2.1. # Context: This project refreshed and extended techno-economic studies of current generation (benchmark) CO2 capture technologies for gas fired power stations and provided comparable information on one or more next generation technologies. It produced a new benchmark incorporating exhaust gas recycle and provided robust, independent and directly comparable technology assessments of specific technologies being considered for further demonstration. # Disclaimer: The Energy Technologies Institute is making this document available to use under the Energy Technologies Institute Open Licence for Materials.
