Descrizione del progetto
Un solido trasferimento di energia solare
Gli impianti a energia solare concentrata (CSP) convertono l’energia solare in energia elettrica utilizzando specchi o lenti per concentrare una grande area di luce solare su una piccola area. Il calore generato viene di solito trasferito ad un sale fuso. Il progetto HIFLEX, finanziato dall’UE, metterà alla prova un prototipo CSP flessibile in cui i sali fusi convenzionali saranno sostituiti da una sospensione di particelle solide in grado di immagazzinare e trasferire calore. Il sistema di accumulo termico funzionerà a temperature di circa 700 gradi Celsius e si prevede che fornirà una densità di accumulo di energia 2,5 volte superiore ad un costo di accumulo di energia inferiore del 50 %. Il prototipo pre-commerciale sarà costruito e testato in un pastificio di Foggia, in Italia.
Obiettivo
The HIFLEX (“HIgh Storage Density Solar Power Plant for FLEXible Energy Systems”) proposal has the ambition to develop and demonstrate a complete pre-commercial flexible CSP prototype plant featuring cheap solid particles as storage and heat transfer medium. Operation of the thermal storage system over a temperature span of 700°C results in a 2.5x higher storage density and 50% lower cost. During the project a complete pre-commercial solar tower system will be developed and built. The system will be located at a Barilla pasta plant in Foggia, Italy, with the following components: a 20 MWh thermal storage able to provide 800 kWth for 24h, innovative solar particle receiver with 2.5 MWth peak power, heliostat field with about 6000m² of mirror area, a 620°C particle steam generator, a 100 kW electric heater and a 800 kW fuel heater.
Fast ramping steam generation at 620°C enabling grid balancing will be demonstrated. The renewable-fuel heater ensures weather-independent availability. Further support of grid stability is achieved by using excess or cheap power from the grid to charge the storage for time-shifted electricity production (power-to-heat-to-power).
Continuous long-term operation for 18 months will be conducted to prove the performance. The project aims to verify the technical maturity of the technology for market introduction. Based on the experience from the pre-commercial prototype, the cost reduction potential for a 100 MWe solar tower plant will be validated, as well as the least-cost mix of renewables (PV, wind power, CSP, storage capacity, power-to-heat capacity, renewable fuel) for the future commercial application at Barilla as CHP system will be evaluated.
A business plan will be developed for fast market introduction of the technology. The project will provide a strong showcase, as basis for the exploitation activities to create new market opportunities, reduce market barriers and build confidence into the technology.
