Energy, exergy, and exergoenvironmental assessment of the coupled electrochemical copper-chlorine with the Goswami cycles

ABSTRACT

A novel hybrid combination of the copper–chlorine (Cu–Cl) thermochemical cycle and the Goswami cycle is planned for electrical, cooling, and hydrogen production. In this cycle, geothermal (renewable energy) and natural gas (nonrenewable energy) are used to provide the energy requirements of this multigeneration system. The natural gas in this cycle is used to comply the requirement of the temperature limit for the reaction of the Cu–Cl cycle. This miultigernration system is investigated versus energy, exergy, and exergoenvironmental aspects. The results of this analysis represent this proposed system produces 259.2 tons of hydrogen, 7.82 MWh of electrical energy, and 13.1 MWh of cooling energy over the year. The exergy efficiency for the Cuexergy efficiencyCl, Goswami cycle, and the whole cycle is obtained as 75.8%, 28.7%, and 13.9%, respectively. Moreover, the exergoenvironmental analysis reveals this factor for the Cu–Cl and Goswami cycles is calculated as 0.61 and 1.24, respectively, and for the whole system is equal to 0.68.
