RESUMO:

The CO₂ capture and storage (CCS) and concentrated solar power (CSP) from power plants are potential emissions mitigation systems. A natural gas combined cycle in Brazil is taken as case study, and these two options are analyzed and compared using exergoeconomic and exergoenvironmental impact (EI) approach for electricity production. The CSP technology used is a parabolic trough collector (PTC) and the environmental impact indicator used is the eco-indicator 99. A detailed assessment of cost and EI for components, input and infrastructure were carried out. The outcomes indicate a decrease of the EI rate of CCS (2^nd case) by 70% and a decrease in specific EI of PTC (3^rd case) by 1.78%. On the other hand, the specific costs of electricity were increased for both options by 15.90 % for the CCS and by 9.78% for the PTC. Discussions about further improvements have been proposed.
