In this proposed work, a thermodynamic performance evaluation of calcium bromide (Ca-Br-2) hybrid thermochemical cycle is investigated for hydrogen generation. This cycle consists of two chemical reactions and one electrochemical reaction. Energy and exergy efficiencies of each step and overall cycle are examined according to several parameters such as reference and reaction temperatures. In addition, we have conducted pure thermodynamic analyses according to the heat demand of steps and reference temperature. Results indicate that the total heat demand and overall exergy destruction rate of Ca-Br-2 cycle computed as 409 kJ/mole H-2 and 183.55 409 kJ/mole H-2, respectively. In addition, energy and exergy efficiencies of the examined cycle are found as 46.64% and 59.04%, respectively, at 25 degrees C reference temperature.eninfo:eu-repo/semantics/closedAccessEnergyExergyHydrogenCa-Br-2Article17327929610.1504/IJGW.2019.098512Q3WOS:000462461900004N/A
