“…In addition, for more environmentally benign outcomes, the sun energy can be utilized as power source for hybrid solar thermal and integrated photo electrochemical systems. In this vein, many studies focus on systems that can produce H2, and treat WW in situ [7,3,14]. Several processes can be used for industrial WW treatment, such as biological, adsorption, advanced oxidation, chemical and ETCG, and membrane separation processes.…”

“…ETCG can be quite effective in treating these industrial effluents. This process comprises metallic cations generation, which occurs at the anode, and H2 production, which takes place at the cathode [3]. Electrochemical methods are used to remove various pollutant organic and inorganic species from WW.…”

“…The fact that these resources are limited highlights the need for RES. Furthermore, the use of FF harms human health and various forms of life existing in the environment, by causing air pollution and global warming [1][2][3][4]. Unquestionably, the global demand for more energy production, and environmental concerns are two of the most significant topics in the 21 st century.…”

“…A significant part of the world total energy consumed is associated with transports, leading to the emission of harmful gases in the atmosphere, so the current transportation systems will no longer remain sustainable [4][5][6]. There is a global effort to reduce GHG emissions  The abbreviations list is in pages 73-74. associated with FF, since their use has a tremendous destructive environmental impact, such as climate change, O3 layer depletion, acidification and air pollution [3,7,8]. To meet the challenges of climate change and depletion of natural ES, energy systems need to be sustainable, efficient, convenient and safe.…”

Due to its highest gravimetric energy density, H2 has been regarded as the preferred cleanenergy carrier, with potentially environmentally-friendly production through the solarassisted WS. Since human activities generate enormous amounts of WW, H2 production from this new resource has gained attention as an emergent technology. This paper addresses the most relevant and current aspects of H2 production from WWEL, and electricity generation from RES. In this sense, the state of art of H2 production, especially from WS, is presented here, as well as the main approaches to electricity generation from RES, with the greatest potential for viability. A new approach on this matter, which is part of the work that is being developed by the authors of this study, was also herein presented.

“…Over the last decade, wastewater treatment through electrocatalysis has attracted numerous attentions by virtue of the high efficiency, feasibility and environmental friendliness. [137,138] Many pollutants in wastewater possessing various active functional groups with low thermodynamic oxidation potential, making them promising to be coupled with the HER in the HWE for low-voltage H 2 generation. Compared with biomass refining, active anodic pollutants, such as urea, ammonia, and hydrazine, usually possess low molecular weight and high solubility, presenting practical onset potentials far lower than biomass oxidation.…”
