Optimal coupling of waste and concentrated solar for the constant production of electricity over a year. AIChE J. 2019; 65:e16559. https://doi.org/10.1002/aic.16559 1547-5905 http://hdl.handle.net/10366/139816 10.1002/aic.16559 [EN]In this paper a biogas-based Brayton cycle is integrated with a concentrated solar power facility. The gas turbine hot flue gas and the molten salts are used to generate steam for the regenerative Rankine cycle. The process model is solved as a non-linear optimization problem within a multiperiod scheme to decide on the contribution of the energy resources and the operating conditions of the facility to meet a certain demand of power over a year mitigating the absence of solar availability. The steam turbine is responsible for power production while the gas turbine works mainly as a combustion chamber. In the South of Spain an excess of biogas is available during summer yielding a production cost of electricity of 0.17€/kWh with an investment of 380 M€ for a production facility of 25MW. This plant is not yet economic. application/pdf eng Renewable Power Waste Solar energy Multiperiod optimization 3303 Ingeniería y Tecnología Químicas 3310.05 Ingeniería de Procesos Optimal coupling of waste and concentrated solar for the constant production of electricity over a year info:eu-repo/semantics/article https://doi.org/10.1002/aic.16559 SA026G18 info:eu-repo/semantics/openAccess
