Techno-economic modelling and cost functions of CO2 capture processes

The paper contributes to techno-economic modelling of CO2 capture process in coalfired power plants. Technological options of CO2 capture have been chosen and cost estimation relationships (CERs) for the chosen options provided. The CERs are being fitted into a developed overall model of carbon capture and sequestration. Functions relating capital costs, operation and maintenance costs and total annualised costs to plant electricity output and amount of CO2 avoided have been developed. The influence of interest rates and plant life has also been analysed.
