Abstract:
Problems related to the growing participation of variable renewable energy (VRE) in electricity grids have renewed interest in alternative renewable energy technologies, such as concentrated solar power (CSP), thanks to its ability to provide dispatchable renewable energy. CSP plants can be dispatchable through thermal energy storage (TES) systems or thermal backup through renewable fuels such as biomass. This study investigates the hybridization of a 50 MWe Solar Tower (ST) plant with a biomass direct combustion boiler at various thermal storage capacities. Seville's solar resource is used as a case study to evaluate the technical benefits of hybridization and the TES role in reducing both the operational intensity on the biomass block and the uncertainty related to its feedstock supply. Results show that integrating a parallel 50 MWe biomass boiler allows the CSP plant to reach capacity factors close to 100% while increasing its electrical efficiency by up to 10% compared to a conventional CSP system. The inclusion of large TES capacities reduces by half the annual demand for biomass and accentuates the seasonal complementarity between solar and biomass resources.
