| Abstract | This article presents first results from the techno-economic evaluation of a 1000 MWel oxyfuel lignitefired power plant with advanced supercritial steam parameters and CO2 capture. The process is based on a reference design that was developed using the same boundary conditions and near-future conventional power plant equipment which reflects the next generation of lignite-fired power plants with efficiencies close to 50 %. The results show, as expected, that there is a considerable decrease in electric power plant efficiency due to the sequestration of the produced CO2. However, preliminary estimations for the investment costs of the main components and operational costs reveal benefits for a scenario in which emitted CO2 has a certain price, according to the certificate system for the EU started in 2005. Based on these data an assesment scheme is presented that allows for evaluation of the process both from an energetic and an economic point of view. The evaluation is based on only a limited number of parameters as input and makes a clear difference between captured CO2 and avoided CO2 emissions. |
