This study investigated the potential of a combined solar and biomass energy system for high pressure steam production. The proposed setup comprised a cold tank, a central receiver, a hot tank, a fluidized bed combustor, a steam turbine, and a condenser. The integrated system was built, simulated, and modelled with the help of two different software system advisor models (SAM) and TRNSYS. Thermodynamic modelling and simulation were also used to identify the optimum operational conditions, and to determine the efficiency and performance of the system. The results obtained in this study suggested that with the setup proposed it was possible to produce a work output of 1.5MW, assuming that the biomass combustor efficiency was 75%. Under these conditions, the ideal efficiency of the cycle was 37%, and the actual efficiency of the cycle was 29%.
