Nuevos materiales y recubrimientos

En los últimos años se ha producido un gran interés en las plantas de concentración de energía solar (Concentrating Solar Power, CSP) debido, principalmente, a su probada capacidad de almacenamiento térmico.

Además, las plantas CSP pueden contribuir a reducir las emisiones de CO2, un potencial reconocido por la UE. Sin embargo, aún se necesitan esfuerzos para hacer de la CSP una tecnología económicamente viable para ganar ventaja sobre otras energías renovables y de combustibles fósiles.

Una de las principales medidas para este fin, es aumentar la temperatura de operación de las plantas para alcanzar mayores eficiencias. Esta medida permitiría a su vez la integración del ciclo de potencia de Brayton usando CO2 supercrítico (s-CO2), lo que también supondría, un aumento del rendimiento global de las plantas en comparación con el ciclo de vapor actual (ciclo Rankine).

Planta termosolar
Las condiciones de operación más agresivas implican mayores requerimientos de los materiales de construcción de las plantas. Los nitratos fundidos utilizados actualmente como fluido de transferencia y almacenamiento están limitados a 580ºC, lo que impide un aumento de la eficiencia. Por tanto, para lograr un aumento de la eficiencia de la tecnología termosolar, es necesario encontrar materiales más eficientes que permitan y resistan las nuevas condiciones de operación, pero, sin aumentar los costes.

El proyecto COCO se centra en el desarrollo de nuevos materiales y recubrimientos estructurales avanzados con rendimiento a largo plazo para dos componentes clave:

Fluidos de transferencia de calor y materiales de almacenamiento

Se requieren nuevas mezclas de sales fundidas con un punto de estabilidad de temperatura más alta (hasta 700ºC) para aumentar la eficiencia de la planta. En paralelo, el proyecto COCO se focaliza en el comportamiento de recubrimientos protectores depositados sobre acero austenítico que resistan la corrosión provocada por las nuevas mezclas de sales desarrolladas.

La durabilidad de estos recubrimientos se investiga con las mezclas de sales a 700ºC tanto en condiciones estáticas como dinámicas a escala de laboratorio y en planta piloto.

Ciclo de energía s-CO2

El CO2 supercritico se considera como un fluido de trabajo en los nuevos ciclos de potencia de Brayton debido a su muy bajo valor económico. Pero es necesario investigar la resistencia a la corrosión de los materiales estructurales candidatos en este entorno oxidante.

COCO se enfoca en estudiar el comportamiento frente a la corrosión de varios recubrimientos de proyección termica y depositados por slurries de aluminio en atmósfera de s-CO2, a presión atmosférica y en alta presión después de una exposición a largo plazo.
