Description du projet
Cycles air-CO2 pour des centrales CSP flexibles
Les cycles air-sCO2 se sont imposés comme la toute dernière solution critique pouvant déboucher sur des centrales solaires thermodynamique à concentration (CSP) hautement performantes et flexibles, conformes aux objectifs de l’UE pour 2030. Le projet SHARP-sCO2, financé par l’UE, ouvrira la voie au développement d’une nouvelle génération de centrales CSP hautement performantes et flexibles en couplant le CSP à un cycle d’énergie sCO2 grâce au développement d’un échangeur de chaleur sCO2-air très performant. Le projet travaillera sur les cycles énergétiques CSP-sCO2 et utilisera l’air comme fluide de fonctionnement. Il développera de nouvelles technologies permettant d’atteindre des températures d’opération très élevées, garantissant un fonctionnement fiable et flexible, des conditions de travail optimales et un rendement élevé pour le couplage de CSP avec des cycles de puissance sCO2. SHARP-sCO2 démontrera la viabilité technico-économique des cycles CSP air-sCO2.
Objectif
SHARP-sCO2 aims to put the basis to develop a new generation of high efficient and flexible CSP plants. Keeping on working on CSP-sCO2 power cycles and exploiting air as operating fluids also developing novel enabling technologies (receiver, storage etc.), SHARP-sCO2 will attain high working temperatures, guaranteeing reliable and flexible operation, optimal working conditions and high efficiency for the coupling of CSP with sCO2 power cycle thanks to the development of high performant sCO2-air heat exchanger. Leveraging on a smart and integrated hybridization with PV, enabled by the development of an innovative electric heater, SHARP-sCO2 will maximize the production, exploiting PV affordability while counting on the unique energy storage capabilities of CSP plants via thermal media. The latter will be also optimized by developing an innovative high temperature thermal energy storage. SHARP-sCO2, by means of a material selection process driven by environmental and economic criteria and aimed at maximizing the circularity of the solution, will lead also to lower LCOE/CAPEX for future CSP. Developing and validating in EU top level laboratories (IME, KTH, TUD) key cycle components (receiver, storage, HEXs, electric heater) SHARP-sCO2 will prove the effectiveness and techno-economic viability of air-driven/sCO2 CSP cycles. Four prototypes will be investigated in a cross-fertilizing lab campaign (TRL5) also to validate partners’ modeling approach to robustly study cycle integration (via a ”cyber-physical approach”). Taking into account EU/extra-EU solar irradiation, electric market perspectives, environmental, safety/regulation aspects too, the project, which involves EU R&D leaders in CSP sector, will be the first keystone towards the promotion of air-driven/sCO2 cycles as key solution for EU CSP plants targeting 2030 EU targets. The project will assess the holistic impact of SHARP-sCO2 also proposing R&D roadmaps to TRL 9 and market uptake of project innovation.
