Abstract
La implantación de energías renovables es una de las medidas de mayor relevancia en la lucha contra el cambio climático. La energía termosolar se encuentra entre las tecnologías que mayor potencial de desarrollo presenta, pero, para hacerla más competitiva, es necesario aumentar su eficiencia. Para ello, una de las principales estrategias consiste en aumentar la temperatura de operación desde los 565 ºC actuales a valores por encima de los 650 ºC. A día de hoy, este nivel de temperaturas sólo es posible implementarlo en la termosolar de torre central; por ello, las investigaciones de nuevos fluidos que permitan trabajar en esas condiciones, están centrados en esta tecnología.De acuerdo con esto, esta investigación tiene dos líneas diferenciadas, una centrada en evaluar y desarrollar nuevos fluidos que permitan un aumento significativo de la temperatura de operación y una segunda en la que se analizan materiales estructurales capaces de resistir las condiciones de operación asociadas a estos nuevos fluidos...
Renewable energies are one of the most relevant measures against climate change. Among them, Concentrating Solar Power (CSP) shows great potential but, in order to reduce the costs and achieve higher competitiveness, it is critical to improve its efficiency. To this end, the most accepted strategy is to increase the current operating temperature from 565 ° C to values above 650 ° C. Nowadays, this level of temperature is only possible in CSP plants with central tower design; therefore, investigations on new fluids are focused on this technology. Accordingly, this work was structured in two different but interconnected research lines. First line was focused on the evaluation and development of new heat transfer and thermal storage fluids that enable a significant increase in operating temperature. Second research line was aimed at identifying construction materials capable of withstanding the operating conditions associated to these new fluids...
