“…These multi-generation techniques enhance the total system's efficiency (Chadegani et al 2018). To this end, a study reported that the energy and exergy efficiency of a CSP/H 2 system could vary from 33.52 to 71.6% and 20.7 to 36%, respectively (Delpisheh et al 2021;Gill et al 2021). It was also reported that a CSP/H 2 multi-generation system's overall efficiency increases when the solar radiation improves, lowering the electrolyzer's working temperature and growing its current density (Chen et al 2020).…”

Hydrogen energy, as clean and efficient energy, is considered significant support for the construction of a sustainable society in the face of global climate change and the looming energy revolution. Hydrogen is one of the most important chemical substances on earth and can be obtained through various techniques using renewable and nonrenewable energy sources. However, the necessity for a gradual transition to renewable energy sources significantly hampers efforts to identify and implement green hydrogen production paths. Therefore, this paper’s objective is to provide a technological review of the systems of hydrogen production from solar and wind energy utilizing several types of water electrolyzers. The current paper starts with a short brief about the different production techniques. A detailed comparison between water electrolyzer types and a complete illustration of hydrogen production techniques using solar and wind are presented with examples, after which an economic assessment of green hydrogen production by comparing the costs of the discussed renewable sources with other production methods. Finally, the challenges that face the mentioned production methods are illuminated in the current review.

“…Solar thermal collector technology in different temperature ranges with the ability to generate different products is one of these alternative methods. Consequently, high‐temperature solar collectors can be used in power plants 3 . Among these high‐temperature collectors, heliostat collectors with two‐axis tracking motion and point absorber with concentration ratio between 300 and 1500 can supply temperatures between 150°C and 2000°C, which is relatively suitable for use in power plants as well as multi‐generation systems 4 .…”

The trend of global environmental pollution underscores the design and application of technologies capable of operating with clean energy sources such as solar energy. Toward this, the current study presents a novel design of combined cooling, heating, and power production system that utilizes a solar-based heliostat technology with thermal energy storage in combination with a modified Kalina cycle. This cycle has been improved by the smart use of multi-heat recovery method and the employment of an ejector. The performance of this system has been studied in three solar radiation modes, including solar mode (solar radiation in the early and late time of a day), solar and storage mode (solar radiation in the middle of a day), and storage mode (night time). This study is based on the development of a fully validated numerical modeling for these three modes and the use of a parametric study including the effect of several important parameter changes on generated electricity, power to cooling and heating ratios, and energy and exergy efficiencies (electrical and overall).The results show, the net generate electricity of the system in the solar mode, solar and storage mode, and storage mode was 3086, 1891, and 1668 kW, respectively. The electrical energy efficiency for the mentioned modes was 15.81%, 5.38%, and 7.84%, and also the electrical exergy efficiency was 6.56%, 2.81%, and 4.14%, respectively. Finally, the overall energy efficiency for these modes was 66.7%, 39.4%, and 63.9%, and the overall exergy efficiency was 8.95%, 4.86%, and 7.50%, individually.
