Renewable energy sources suffer from an intermittent nature and energy storage systems are a crucial step to increase their reliability.

Le risorse energetiche rinnovabili hanno una natura intermittente e i sistemi di accumulo dell'energia sono fondamentali per aumentare la loro affidabilità. Tra le alternative, i materiali a cambiamento di fase (PCM) sfruttano il passaggio di fase solido-liquido (a temperatura quasi costante) per accumulare energia. I PCM mantengono più bassa la temperatura dei sistemi dove applicati, riducendo le dispersioni di calore verso l'esterno e per auto scarica. Questo lavoro si concentra su applicazioni basate su energia solare, in particolare pannelli fotovoltaici e laghi solari a gradienti salini.

Abstract
Renewable energy sources suffer from an intermittent nature and energy storage systems are a crucial step to increase their reliability. Among the alternatives, Phase Change Materials (PCM) belong to the latent thermal storage group, and exploit the solid-liquid phase change (at nearly constant temperature) to store energy. PCMs allows to reduce the heat loss outwards and the auto-discharge thermal losses, storing energy at lower the temperatures. This work investigates their applications in solar-based system to improve the energy performance, focusing on photovoltaic panels and solar ponds.File | Dimensione | Formato | |
