Abstract

The presented design integrates concentrated solar power (CSP) into a compact ultra-high temperature latent heat thermal energy storage (UHT-LHTES) system using Phase Change Materials (PCM) and Thermophotovoltaic (TPV) cells, creating a Solar-to-Heat-to-Power (S2H2P) storage system ten times more compact than traditional CSP storage. This innovative solution aligns with the European strategy's focus on renewable energy source (RES) flexibility and dispatchability. To optimise this complex system, COMSOL Multiphysics® 6.1 facilitates multiphysics coupling, enabling key parameter optimisation and shape improvements. The results support the selection of the best materials and design configurations. For instance, just with very simple adjustments in the angle of a wall, the system yielded an improvement of 6% by reducing the PCM melting time. This is the first time that an innovative design of this kind has been simulated with a complete CFD model for all the elements compounding the innovative S2H2P system.
