The HRC POWER project proposes a radically new approach combining novel advanced materials and an innovative hybridization technology to make breakthroughs at materials and concept levels: very high temperature operation up to 1300°C with high Carnot efficiency, round-the-clock operation for 95% ACF, high flexibility / dispatchability, low water consumption. Novel materials will consist of advanced absorber metamaterials based on self organized structure and advanced infrared selective emitter refractory crystals. Novel technology / concept will consist of specific micro-combustor operating at very high temperature.This concept is a radically new path for renewable energy hybridization in a solid state device able to provide high quality thermal energy from solar and H2 or Biogas sources to thermal / electrical solid state converters.The main objectives of the HRC POWER project are to develop novel functional materials for advanced building blocks (solar, combustion and hybrid modes), novel high temperature joining technologies (integration of the building blocks) and to realize the proof of concept of this fully new technology, going from the architecture design to the performance assessment.
