“…Techno-economic analysis (TEA) is widely used to evaluate the technical and economic potentials when adopting certain technologies. 86 Previous research has used TEA to evaluate the potential of technology investment decisions, and to guide technical solutions toward improving the overall system value proposition. 87 TEA also involves sensitivity analysis identifying parameters that have the dominant influence on system performance.…”

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.

“…Ali Sohani developed studies on the design of hybrid generation systems with windphotovoltaic energy and hydrogen storage in residential complexes [36] and off-grid systems [37]. He also addressed the techno-economic evaluation of a power generation system that combines rooftop photovoltaic systems and building-based thermal-photovoltaic systems (BIPV/T) employing surplus energy in a hot and cold water storage system [38].…”

“…Within the studies that are in this position (Figure 12), research related to the calculation of the levelized cost of energy for different energy generation systems, having photovoltaics and storage in common, is addressed [43,44,72]. Models have been proposed to make comparisons of different energy storage systems considering technical and economic variables [27,73,74], and others, such as [38,[75][76][77][78][79][80], carry out techno-economic evaluations of energy generation systems with storage. Within these studies, Aguilar-Jiménez et al [78] and Zurita et al [75] considered hybrid power generation systems.…”

Energy production through non-conventional renewable sources allows progress towards meeting the Sustainable Development Objectives and constitutes abundant and reliable sources when combined with storage systems. From a financial viewpoint, renewable energy production projects withstand significant challenges such as competition, irreversibility of investments, high uncertainty levels, and considerable investment amounts. These facts make their financial valuation fundamental for all the agents involved. Using the Web of Science (WoS) and Scopus databases, a scientometric analysis was carried out to understand the methods that have been used in the financial appraisal of photovoltaic energy generation projects with storage systems. The present research project was developed from 268 studies published between 2013 and 2023; tools such as Bibliometrix 4.1.3, VOSViewer 1.6.19, and Tree of Science 0.0.1a9 were used. Two main findings stand out: (i) the most used methods in the literature are the traditional ones, and within them, the levelized cost of energy has been used with greater frequency; and (ii) there is an interest in analyzing the investments of these systems for residences within the framework of distributed energy generation. Two gaps were found in the literature: (i) the studies that were carried out have not comprehensively incorporated the financial challenges faced by these investments; and (ii) the evaluation of these projects has not been addressed from the perspective of a utility-based power generator.
