“…For this reason, it can be said that the effect of temperature on the production amount is very low. With such an increase in the temperature, the values of ΔH and ΔS for the specific reaction decrease and hence the ΔG value declines accordingly at a certain rate [25]. As a result, the amount of hydrogen production decreases slightly with temperature.…”

“…It is stated that it can produce 1321 kg s -1 hydrogen in the cycle, which is planned to operate in nuclear facilities [24]. An exergy analysis was carried out by the same authors and the integration of Na-O-H thermochemical cycle with multigeneration systems was also examined [25]. The integration of thermochemical cycles into multigeneration systems is not unique to the Na-O-H cycle, examples can be found in the literature for other cycles [26,27].…”

The sodium-oxygen-hydrogen (Na-O-H) thermochemical cycle is investigated, as one of the potential methods of thermochemical water decomposition and hydrogen generation. The hydrogen production reaction, metal separation reaction, and hydrolysis reaction, forming the Na-O-H thermochemical cycle, are examined by RGibbs reactor modeling. The parameters for the three reactions are optimized in terms of hydrogen yield, pressure, temperature, and heat requirement. The metal separation reaction is carried out under vacuum pressure, while other reactions can be conducted under atmospheric pressure.

An analysis is reported of a geothermal-based electricity-freshwater system in which an organic Rankine cycle is integrated with a multi-effect distillation desalination unit. The system is driven by geothermal hot water extracted from the production well. Mass, energy, entropy, and exergy rate balances are written for all system components, as are energy and exergy efficiency expressions for each subsystem. The exergy destruction rate associated with the temperature and chemical disequilibrium of the freshwater and brine with the reference environment are taken into account to reveal accurate results for irreversibility sources within the desalination process. The developed thermodynamic model is simulated using thermodynamic properties of the working fluids (i.e., ammonia, seawater, distillate, and brine) at each state point. A sustainability analysis is performed that connects exergy and environmental impact concepts. That assessment expresses the extent of the contribution of the system to sustainable development and reduced environmental impact, using exergy methods. Results of the sustainability analysis indicate that, with an increase in the reference environment temperature from 20 to 35 $$^\circ{\rm C}$$ ∘ C , the exergy destruction rate decreases for the multi-effect distillation and organic Rankine cycle systems respectively from 6474 to 4217 kW and from 16,270 to 13,459 kW. Also, the corresponding sustainability index for the multi-effect distillation and organic Rankine cycle systems increases from 1.16 to 1.2 and 1.5–1.6, respectively, for the same increase in reference environment temperature.
