“…And there are some VRBs that are in demonstration scale with power capacities around 250 kW. VRBs have energy storage capacities around 20 to 30 Wh/L when they are fully charged . Compared with vanadium batteries, zinc‐bromine batteries have some disadvantages; one of them is causing some operational issues because of the uneven zinc accumulation on the electrodes.…”

Summary Affordable, clean, efficient, flexible, and reliable energy storage is an important component of sustainable energy systems. There are several studies in the literature concentrating on improving the sustainability performance of energy storage systems from economic and technical perspectives. However, a comprehensive performance investigation of energy storage systems that take economic, environmental, social, and technical criteria into account is still needed. For that reason, in the present study, it is aimed to perform a complete assessment and analysis of the sustainability of energy storage systems for residential applications in communities and cities. Pumped hydro, conventional batteries, high‐temperature batteries, flow batteries, and hydrogen are the selected energy storage systems. In order to handle the vagueness and ambiguity during the assessment and to eliminate the perceived hesitancy in the decision makers' preferences, an innovative method, a hybrid hesitant fuzzy multicriteria decision‐making (MCDM) methodology composed of hesitant fuzzy analytic hierarchy process (HFAHP) and hesitant fuzzy technique for order preference by similarity to ideal solution (HFTOPSIS), is utilized to assess the sustainability of the selected systems. In this study, four different performance criteria: economic (power cost and energy cost), environmental (pollutant emissions, area requirement, wastewater quality, and solid waste production), social (safety, accessibility, ease of use, and public acceptance), and technical (efficiency, storage capacity, cycling limit, and performance degradation) are taken into consideration. The performance evaluation results indicate that technical performance has the highest influence and social performance has the lowest influence when evaluating the sustainability of the selected energy storage systems. And hydrogen has the highest sustainability performance compared with the other selected energy storage options.

“…Crossover of active species through membrane leads to performance loss over cycling. Redox chemistry of active species with formation of electrodeposits leads to another type of cell configuration without membranes and with only one electrolyte reservoir [7] ( Figure 2c). Some selected membrane-free redox flow batteries are listed in Table 1 [ [8][9][10][11][12][13][14].…”

A redox flow battery is an electrochemical energy storage device that converts chemical energy into electrical energy through reversible oxidation and reduction of working fluids. The concept was initially conceived in 1970s. Clean and sustainable energy supplied from renewable sources in future requires efficient, reliable and cost-effective energy storage systems. Due to the flexibility in system design and competence in scaling cost, redox flow batteries are promising in stationary storage of energy from intermittent sources such as solar and wind. This chapter covers basic principles of electrochemistry in redox flow batteries and provides an overview of status and future challenges. Recent progress in redox couples, membranes and electrode materials will be discussed. New demonstration and commercial development will be addressed.

“…This review revealed that the designs of the membrane‐less fuel cell systems were divided into flow through, flow‐over, and air‐breathing designs. Goulet et al reported on the trends that have been studied in this field, whereas Bamgbopa et al summarized the membrane‐less redox flow battery system; however, the majority of the materials used in the review were from a membrane‐less fuel cell system. The author reviewed five major designs of membrane‐less cell systems: (a) single‐phase colaminar flow (SLF), (b) flowing electrolyte detached by flowing stream of a supporting electrolyte (FSE), (c) multiphase colaminar flow (MLF), (d) membrane‐less hybrid flow battery (MHFB), and (e) ionically inert solid separator (IISS).…”

Membrane‐less micro fuel cell system design and performance: An overview

Researchers interest in using fuel cells as a power source has grown because fuel cells are environmentally friendly. However, fuel cells still present challenges due to their performance and cost. This limits the commercialization of fuel cell systems, particularly in liquid fuel cells. One of the major obstacles is the Nafion membrane. The Nafion membrane is extremely expensive and causes the "fuel crossover phenomenon." Therefore, researchers have proposed a membrane-less fuel cell that eliminates the need of a membrane in the system mainly in micro fuel cells. Membrane-less fuel cell has shown an improvement on power density by approximately 12% compared with conventional type of proton electrolyte membrane fuel cell. However, there still a lack of information on system design and performance. Therefore, the main objective of this review is to present an extensive study focusing on the geometrical system design and performance of a membrane-less fuel cell system. It also presents the different types of membrane-less fuel cell systems. Lastly, it highlights the current problems and potentials to improve the performance of the system. Finally, it is observed that the cost of a membrane fuel cell can be reduced by 20% to 40% compared with the conventional type of fuel cell.
