  • SHARP-SCO2 – Solar Hybrid Air-sCO2 Power Plants

    SHARP-sCO2 addresses key technological challenges to enable the development of a new generation of highly efficient and flexible CSP plants. Keeping on working with CSP-sCO2 power cycles and investigating how to exploit air as operating fluid, SHARP-sCO2 will develop and validate novel enabling technologies in EU top level labs. SHARP-sCO2 will attain high temperatures and cycle efficiency, while guaranteeing reliable and flexible operation. Introducing a smart hybridization with PV by means of an innovative electric heaters, SHARP-sCO2 will maximize sCO2 operation and remuneration, exploiting PV affordability while counting on the unique energy storage capabilities of CSP.

  • HYBRIDplus – Advanced HYBRID solar plant with PCM storage solutions in sCO2 cycles

    HYBRIDplus aims to pioneer the next generation of CSP with an advanced high-density and high-temperature thermal energy storage (TES) system capable of providing a high degree of dispatchability at a low cost and with a much lower environmental burden than the State of the Art. This thermal storage is based on the Phase Change Material (PCM) technology in a cascade configuration that can reproduce the effect of a thermocline and integrates recycled metal wool in its nucleus. This enables hybridization with PV by acting as an electric heater transforming non-dispatchable renewable electricity into thermal stored energy ready to be dispatched when needed. HYBRIDplus proposes a novel concept to hybridize PV+Cascade PCM-TES with CSP configuration based on a high-temperature supercritical CO2 cycle working at 600 ºC. This new plant is called to form the backbone of the next-generation energy system thanks to higher efficiency and lower LCOE than state-of-the-art technology.

  • 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.

  • 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.
