Generation I utilises molten salts, while Generation II employs solid particles, enabling higher cycle temperatures of 700 °C compared to 550 °C in Generation I. Cost analysis estimates specific power block costs of 1353 and 1508 €/kW for Generation I and II, respectively, which are comparable to state-of-the-art steam turbines but offer efficiency gains of 3.8 and 11 p.p. The primary heat exchanger is the dominant cost driver, accounting for up to 48% of direct costs. An optimisation of the solar multiple and storage hours for a reference site in Seville (1773 kWh/m2/year) indicates that SCARABEUS CSP concepts can significantly reduce the levelised cost of electricity by 4.4 €/MWh and 20.5 €/MWh with respect to SoA (135 €/MWh). A Pareto-based analysis explores trade-offs between total plant cost and levelised cost of electricity, identifying cost-effective designs that reduce total plant cost and levelised cost of electricity by 3.9% for Generation I and 14.5% for Generation II. These outcomes confirm the SCARABEUS concept as a promising alternative to enhance the economic competitiveness of next-generation CSP plants.ElsevierIngeniería EnergéticaEuropean Union (UE).
