Estudo de fluidos térmicos aplicados à energia termossolar

Abstract

The Brazilian electricity matrix is being diversified due to the depletion of hydroelectric generation potential, a source that was responsible for more than 80% of the National Interconnected System (SIN). The main reflection of this diversification is wind generation, which has doubled its participation in the last decade, and solar energy, which has proven to be a n advantageous option due to the high levels of solar irradiation in almost all of Brazil. For conversion of solar energy into electrical energy there are two principles, the direct and indirect conversion that happens through Concentrating Solar Power C SP, technology studied in this monograph. CSP technology is not considered developed in Brazil, although it is already considered mature internationally. One of its main advantages is related to its heat storage capacity, which allows this system to genera te electricity even at times without sunlight. Heat is stored in thermal fluids, which will be addressed in this monograph to show which are the most used and what are their advantages and disadvantages. A study will also be presented on the environmental impacts and life cycle of a CSP plant.
