Modeling and control of a fluidized-particle-based solar receiver at MW-scale

Fluidized solid particles in concentrated solar power have shown the potential to induce higher global efficiencies compared to conventional heat transfer fluids. By maintaining their physicochemical stability at higher temperatures than synthetic oils and molten salts (600–750°C), they reduce storage issues and reach more efficient conversion cycles. Within the framework of the European project Powder2Power, which aims to demonstrate the feasibility of such a CSP central tower plant prototype at MW scale (TRL7), this work focuses on the thermal modeling and control of the tubular solar receiver.
