• 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.
