  • FLUWS — Flexible Upcycled Waste Material based Sensible Thermal Energy Storage for CSP

    FLUWS aims to develop and validate a more flexible, reliable, environmentally friendly and cost-effective thermal energy storage (TES) system futureproofed for next generation concentrating solar power (CSP) plants operating at higher temperatures and hybridized with PV, which are recognized as the two main paths for reaching cost-efficiency of CSP in the near future. Specifically, FLUWS validates up to TRL 5 a novel TES concept that ensures elevated thermal efficiency with minimum environmental impact thanks to on the one hand the upcycling of waste and residual materials from the ceramic industry and the use of air as heat transfer fluid, and on the other thanks to building on previous consortium know-how in the development of new cost-effective radial packed-bed TES and materials for high temperature applications. The new FLUWS TES will enable more flexible and modular CSP systems as it will have embedded electric heaters driven by renewable electricity and will be designed for easier integration with compact gas Brayton cycles (i.e. supercritical CO2 and air-driven), thus facilitating the provision of additional services from CSP to the grid and widening the applications of CSP as a competitive technology for combined heat and power in the industrial sector.

  • eLITHE – Electrification of ceramic industries high temperature heating equipment

    eLITHE aims to support the electrification of the ceramic industries by demonstrating sustainable and cost-effective pathways to electrify high temperature thermal processes (>1,000ºC) from the ceramic industry. Three different processes will be demonstrated at 3 different pilot sites at relevant scale: 1. A ceramic frits smelter (1,100-1,500ºC) combining induction and resistive heating through electrodes. 2. A microwave-based calcination furnace (1,200ºC) for the calcination of alumina. 3. A tunnel kiln (1,100ºC) combining radiant walls and flexible hybrid burners for bricks and tiles firing. These technologies will be endorsed through the application of advanced modelling techniques to develop Digital Twins (DTs) of each of them, as a core tool to support design and operation. eLITHE will also involve material science to develop novel products and refractory materials compositions adapted to the new requirements of electrified processes and will test waste materials derived from the ceramic industry for high temperature energy storage applications, improving the sector circularity.
