Descrizione del progetto
Le centrali elettriche a combustibili fossili si adattano all’integrazione delle energie rinnovabili
Le attuali centrali elettriche a combustibili fossili sono state progettate per fornire una potenza costante e stabile. A causa della crescente quota di energie rinnovabili, questi impianti devono adattarsi a fornire energia di riserva fluttuante e a garantire la stabilità della rete. Il progetto sCO2-Flex, finanziato dall’UE, affronterà questa sfida sviluppando e convalidando un ciclo di Brayton scalabile da 25 MWe che utilizza CO2 supercritica, aumentando la flessibilità operativa e l’efficienza delle centrali elettriche a carbone e lignite. I ricercatori cercheranno di ottimizzare la progettazione e i componenti per adattarsi meglio alle mutevoli esigenze di potenza, per consentire regolazioni più rapide della produzione di energia e per ridurre al minimo i danni ambientali, aumentando al contempo l’efficacia in termini di costi. Portando il ciclo sCO2 al TRL6, sCO2-Flex apre la strada a futuri progetti dimostrativi e alla commercializzazione della tecnologia.
Obiettivo
Current fossil-fuel power plants have been designed to operate in base-load conditions, i.e to provide a constant power output. However, their role is changing, due to the growing share of renewables, both in and outside the EU. Fossil-fuel plants will increasingly be expected to provide fluctuating back-up power, to foster the integration of intermittent renewable energy sources and to provide stability to the grid. However, these plants are not fit to undergo power output fluctuations.
In this context, sCO2-Flex consortium addressees this challenge by developing and validating (at simulation level the global cycle and at relevant environment boiler, heat exchanger(HX) and turbomachinery) the scalable/modular design of a 25MWe Brayton cycle using supercritical CO2, able to increase the operational flexibility and the efficiency of existing and future coal and lignite power plants.
sCO2-Flex will develop and optimize the design of a 25MWe sCO2 Brayton cycle and of its main components (boiler, HX, turbomachinery, instrumentation and control strategies) able to meet long-term flexibility requirements, enabling entire load range optimization with fast load changes, fast start-ups and shut-downs, while reducing environmental impacts and focusing on cost-effectiveness. The project, bringing the sCO2 cycle to TRL6, will pave the way to future demonstration projects (from 2020) and to commercialization of the technology (from 2025). Ambitious exploitation and dissemination activities will be set up to ensure proper market uptake.
Consortium brings together ten partners, i.e academics (experts in thermodynamic cycle/control/simulation, heat exchanging, thermoelectric power, materials), technology providers (HX, Turbomachinery) and power plant operator (EDF-coordinator) covering the whole value chain, constituting an interdisciplinary group of experienced partners, each of them providing its specific expertise and contributing to the achievement of the project’s objectives.
