This work is part of the European project “Powder-to-Power” (P2P) that aims to demonstrate at the MW-scale the operation of an original and cheap particle-driven CSP technology applicable for both power and industrial heat production. A complete installation is currently under implementation including the heat collection loop and the power block. The unit will use the fluidized bed-in-tube solar receiver concept. This project is following the previous NextCSP project (2017-2021) which has permitted achieving a first test campaign highlighting some issues. Consequently, a new configuration will be implemented and tested during a full year experimental campaign. The final objective of the project is the evaluation of the expected techno-economic and sustainability performance of the concept at utility-scale considering a 10-60 MWe power plant. The up-scaling process will be based on validated models and operational data.
