“…Their study analyzed the impact of distillation effects on optimal solutions, resulting in cost-effective configurations for the multi-generation system. In addition, Khanmohammadi et al [21] explored the past thermodynamic modeling and multi-objective optimization of a solar-based poly-generation unit generating hot water, heating, cooling, hydrogen, and freshwater via a humidification and dehumidification (HDH) unit. With high-radiation areas facing water scarcity, solar-based systems were considered promising.…”

The multi-generation systems with simultaneous production of power by renewable energy, in addition to polymer electrolyte membrane electrolyzer and fuel cell (PEMFC-PEMEC) energy storage, have become more and more popular over the past few years. The fresh water provision for PEMECs in such systems is taken into account as one of the main challenges for them, where conventional desalination technologies such as reverse osmosis (RO) and mechanical vapor compression (MVC) impose high electricity consumption and costs. Taking this point into consideration, as a novelty, solar still (ST) desalination is applied as an alternative to RO and MVC for better techno-economic justifiability. The comparison, made for a residential building complex in Hawaii in the US as the case study demonstrated much higher technical and economic benefits when using ST compared with both MVC and RO. The photovoltaic (PV) installed capacity decreased by 11.6 and 7.3 kW compared with MVC and RO, while the size of the electrolyzer declined by 9.44 and 6.13%, and the hydrogen storage tank became 522.1 and 319.3 m3 smaller, respectively. Thanks to the considerable drop in the purchase price of components, the payback period (PBP) dropped by 3.109 years compared with MVC and 2.801 years compared with RO, which is significant. Moreover, the conducted parametric study implied the high technical and economic viability of the system with ST for a wide range of building loads, including high values.

Purpose: To carry out a bibliographic study reviewing scientific works related to hydrogen and thermal/photovoltaic solar energy being published within Brazil and globally. Method/design/approach: The Bibliometrics R tool was applied to analyse document data extracted from the Scopus database. Results and conclusion: Over three thousand documents about hydrogen with photovoltaic energy were found, published in 1,200 journals. Near 6,600 documents were catalogued for the general issue of hydrogen and solar energy. The number of publications per year continuously grew from 1975 to 2022, reaching 200 in recent years. Research implications: The theme related to hydrogen and photovoltaic solar energy still needs to gain space in Brazil, as the number of publications is modest compared with other countries. The present work shows that, despite the increasing attention that this theme is receiving, a lot of potential remains unexplored. Originality/value: This study seeks to map and identify the main published works on hydrogen production from solar-photovoltaic and solar-thermal sources. The study focuses on the global as well as the Brazilian scenario and uses the Scopus database in association with the Bibliometrix R tool to analyse the reported data.

“…Therefore, the utilization of alternative water resources, like sewage, ocean, and atmospheric water, via solar-energy-mediated desalination techniques, has become necessary to address water scarcity and dependence on fossil fuels. In contrast to the conventional approach of water evaporation, which involves the utilization of different types of solar collectors like parabolic troughs − and solar heliostat, , an interfacial steam generation technology employs a photothermal evaporator to concentrate heat instead of dispersing it throughout the entire water volume. This approach has been shown to achieve evaporation efficiencies exceeding 65%. , Consequently, the utilization of the interfacial steam generation technique in desalination has demonstrated its efficacy as a sustainable approach to addressing water security concerns .…”

Sorption-assisted atmospheric water harvesting (SAWH) is a promising strategy to mitigate the worldwide upsurge in freshwater demand. To empower the sustainable approach, suitable sorbent materials such as hydrogels, metal–organic frameworks (MOFs) and their composite structures have gained significant attention at the advent of their unique surface features like tunable porosity, high surface area, stimuli-responsiveness, and absorption desorption channels through functional sites. Delving into challenges associated with SAWH, we have presented a composite sorbent material consisting of alanine amino acid-based hydrogel and Al MOF. Stressing upon the fine-tuning of two individual sorbents, we designed several hydrogel-MOF composites and optimized the concentration of Al-MOF with 7.5 wt % of 0.5AHN with the best water uptake, moisture sorption, and desalination efficiency. The synergistic combination of inherently zwitterionic amino acid-based hydrogels with MOF opened up extended water uptake channels for the overall composite. As a result of such irreversible interaction, 0.5AHN_AlM(7.5) exhibited the highest sorption capacity of 2.21 g g–1 at 90% RH, whereas 0.26 and 0.47 g g–1 moisture uptake was measured at humidity levels of 40% RH and 60% RH, respectively. Moreover, with an evaporation rate of 0.79 kg m–2 h–1, 3.4 g of saline water was converted into freshwater within 3.5 h of solar irradiation to demonstrate its desalination efficiency. This study aims to establish a strategic method for creating environmentally friendly and effective composite materials that can be used to enhance and automate solar-powered SAWH.
