  • POWDER2POWER (P2P) – MW-scale fluidized particle-driven CSP prototype demonstration

    P2P project aims to demonstrate at the MW-scale (TRL7) the operation of an innovative, cost effective and more reliable complete fluidized particle-driven Concentrated Solar Technology that can be applied for both power and industrial heat production. The prototype to be developed and tested is based on the modification and the improvement of an experimental loop built in the framework of the previous H2020 project Next-CSP. It will include all the components of a commercial plant, a multi-tube fluidized bed solar receiver (2 MWth), an electricity-driven particle superheater (300 kW), a hot store, a particle-to-working fluid crossflow fluidized bed heat exchanger (2 MWth), a turbine (hybrid Brayton cycle gas turbine, 1.2 MWe), a cold store and a vertical particle transport system (~100 m). The addition of an electricity-driven particle superheater will enable to validate a hybridized PV-CSP system working at 750°C that is expected to result in electricity cost reduction and efficiency improvement with respect to state-of-the-art.

  • HYBRIDplus – Advanced HYBRID solar plant with PCM storage solutions in sCO2 cycles

    HYBRIDplus aims to pioneer the next generation of CSP with an advanced high-density and high-temperature thermal energy storage (TES) system capable of providing a high degree of dispatchability at a low cost and with a much lower environmental burden than the State of the Art. This thermal storage is based on the Phase Change Material (PCM) technology in a cascade configuration that can reproduce the effect of a thermocline and integrates recycled metal wool in its nucleus. This enables hybridization with PV by acting as an electric heater transforming non-dispatchable renewable electricity into thermal stored energy ready to be dispatched when needed. HYBRIDplus proposes a novel concept to hybridize PV+Cascade PCM-TES with CSP configuration based on a high-temperature supercritical CO2 cycle working at 600 ºC. This new plant is called to form the backbone of the next-generation energy system thanks to higher efficiency and lower LCOE than state-of-the-art technology.
