Advancing Thermal Energy Storage for Concentrating Solar Power (CSP)

FLUWS (Flexible Upcycled Waste Material based Sensible Thermal Energy Storage for CSP) is an innovative project, funded by Horizon Europe and UKRI, dedicated to advancing thermal energy storage (TES) systems for the next generation of concentrating solar power (CSP) plants. This initiative focuses on developing an adaptable, dependable, environmentally friendly, and highly cost-efficient TES solution. The system is engineered to operate at higher temperatures, synergizing with photovoltaic (PV) technology to significantly enhance overall system cost-efficiency and performance.

Innovative Material and Heat Transfer Fluid Integration

The core innovation of FLUWS lies in its novel TES concept, which uniquely integrates recycled materials sourced from the ceramic industry. By utilizing these waste materials in conjunction with air as a heat transfer fluid, the project aims to achieve exceptional thermal efficiency while drastically minimizing environmental impact. This approach represents a significant step towards sustainable energy solutions, effectively transforming industrial byproducts into critical components for advanced renewable energy infrastructure.

Enhanced Flexibility and Grid Integration

Beyond material development, FLUWS is also committed to designing new TES systems, including advanced electric heaters powered by renewable energy sources. These developments are crucial for making CSP systems more flexible and seamlessly integratable with diverse energy technologies and the broader electricity grid. The enhanced flexibility will enable CSP plants to provide expanded grid services and unlock new industrial applications, thereby strengthening the role of solar thermal energy in the global energy transition.

The project is structured for a 36-month duration, involving 12 partners across 6 countries, and is supported by approximately 2.5 million EUR in funding. Its deliverables are poised to not only improve the technical and economic viability of CSP but also to champion circular economy principles within the energy sector, fostering a more resilient and sustainable energy future.
