“…There is a significant body of literature devoted to exploring opportunities for utilizing RESs in Tunisia, as evidenced by previous studies (Attig-Bahar et al, 2021;Balghouthi et al, 2016;Harrabi et al, 2023;Rekik and El Alimi, 2023;Trabelsi et al, 2016). However, there is currently a gap in research investigating the implementation of hybrid CSP-PV-wind turbine-based power generation systems, specifically in the Tataouine region, southernmost Tunisia.…”

Renewable energy systems have emerged as a viable option to mitigate the environmental impacts of traditional fossil fuels. However, the intermittent nature of these renewables, such as solar and wind, makes it challenging to ensure a stable energy supply using only one type. Therefore, combining more than a single technology offers significant advantages in addressing the limitations associated with each individual system. Nevertheless, developing these systems requires substantial financial investments, making it crucial to identify the most suitable locations prior to installing them. In this article, the prime objective was to propose a preliminary evaluation of land suitability for constructing solar and wind hybrid facilities (PV–wind, PV–CSP, and CS–wind) in Tataouine, southern Tunisia. To this end, a GIS-based MCDA methodology was developed based on an extensive literature review and experts’ feedback while considering climate, topography, accessibility, and environmental factors. The results obtained revealed that the optimal area for a CSP–PV hybrid system is about 793 km2, indicating that this combination has the highest potential in terms of available resources and compatibility. On the other hand, well-suited locations for hosting CSP–wind and PV–wind systems covered areas of 412 and 333 km2, respectively. Such specific locations are capable of generating an annual technical potential of 316.169, 91.252, and 62.970 TWh for CSP–PV, CSP–wind, and PV–wind, respectively. Interestingly, comprising almost all of the most appropriate sites, Remada and Dhiba stand as the ideal locations for accommodating such hybrid systems. Considering this outcome, Tataouine can position itself as a model for renewable energy adoption in Tunisia. Therefore, it is imperative for policymakers, investors, and local communities to collaborate and embrace these hybrid systems to capitalize on this immense potential and pave the way for a greener and more prosperous future.

“…Solar energy is the most desirable, accessible type among numerous renewable energies due to its availability and sustainability (Esen and Yuksel, 2013;Liu et al, 2023;Shah et al, 2022). Many techniques have been developed and introduced recently to harness this type of renewable energy (Esen et al, 2017;Farzan et al, 2022;Harrabi et al, 2022). Integrated collector storage (ICS) systems are a wise, affordable method to heat water for domestic and industrial applications (Messaouda et al, 2020;Panahi et al, 2019).…”

Thermal diodes are a novel method to rectify the heat transfer mechanism, and this technique helps reduce heat losses in solar thermal collectors. The current study introduced a new planar thermal diode integrated collector storage (ICS) solar water heating system to analyze the effectiveness of the newly introduced thermal diode in reducing heat losses. This thermal diode ICS system utilizes water as phase change materials to transfer heat through evaporation and condensation. Three scenarios were considered to assess the dynamics of the thermal diode ICS: atmospheric-pressure and depressurized thermal diodes, Ppartial = 0, -0.2, -0.4 bar. The water temperature reached 40 oC, 46 oC, and 42 oC in Ppartial = 0, -0.2, and − 0.4 bar, respectively. The heat gain coefficients are 38.61, 40.65, and 39.26 W/K, while the heat loss coefficients are 9.56, 5.16, and 7.03 W/K in Ppartial = 0, -0.2, and − 0.4 bar, respectively. The optimum heat collection and retention efficiencies are 45.3% and 33.5% in Ppartial = -0.2 bar. Hence, there is an optimum partial pressure to achieve the best performance, equal to -0.2 bar. The acquired results illustrate the robustness of the planar thermal diode in reducing heat losses and rectifying the heat transfer mechanism.

This work analyzes the performance of a new Integrated Collector Storage Solar Water Heater (ICSSWH) by using Dynamic System Testing (DST) method according to Standard ISO 9459‐5. The long‐term performance study of the system in different climatic conditions has been achieved by a coupling model between DST results and a numerical approach based on the system transient behavior. Results of the experimental dynamic system evaluation showed that the total store heat capacity Cs, the useful collector surface Ac* and the storage tank heat losses coefficient Us are, respectively, 0.87 MJ/K, 1.21 m2 and 10 W/K. In Tunisian climatic conditions, the ICSSWH system allows covering until 79.3% from a typical family need for a daily consumption of 170 L. The results found allow optimizing the energy gain of the ICSSWH as well as selecting a specific load volume according to the location. Especially, investigations showed that in Stockholm and Riadh climatic conditions, the ICSSWH's solar fraction reached 27% and 83%, respectively, for a daily load volume of 250 L. More importantly, the experimental effort of DST identification can be minimized by coupling DST data with a robust numerical approach.
