“…For off-grid RES, the most often used ESS is battery storage (BS)-for small scale-and pumped hydro storage (PHS)-for large scale-owing to their maturity level and low levelized cost of storing energy compared with other available ESS options (Yang and Jackson, 2011;Zhang et al, 2018;May et al, 2018;Schoenung and Hassenzahl, 2003;Krishnakumar et al, 2019;Stocks et al, 2020). PHS has recently emerged and is seen as a benign option for the assessment of energy mix options with the high penetration of low-carbon sources.…”

“…PHS has recently emerged and is seen as a benign option for the assessment of energy mix options with the high penetration of low-carbon sources. A recent study investigated the global off-river locations for PHS and identified 616,000 potential locations, revealing the available excessive storage options to exploit the solar and wind potential, especially for the remote sites (Stocks et al, 2020). On the other hand, many literature studies have proposed BS for RES owing to its advantages over other ESS such as high efficiency, fast response time, and scaling feasibility due to modular structure (Hesse et al, 2017).…”

“…Solar and wind energy are two major pillars of renewable energy resources with the largest (97 GW) and second largest (59 GW) electricity generation capacity in 2019, respectively (Stocks et al, 2020). Moreover, the cost of producing electricity from these technologies has dropped consistently where it is lowest in many regions and is expected to further reduce in the coming decade (Gul et al, 2016;Trancik et al, 2015;Fu et al, 2016;EIA, 2016;Mills and Wiser, 2012;Ziegler et al, 2019;Schmidt et al, 2017).…”

Addressing climate change with the rising global energy usage necessitates electricity sector decarbonization by rapidly moving toward flexible and efficient off-grid renewable energy systems (RESs). This paper analyzes the wind and solar micro-grids, with batteries and pumped hydro storage for a robust off-grid RES techno-economic operation, while considering diverse multi-objective optimization cases. This research has considered the RES variable operational losses in the developed methodology and relations between different indicators are evaluated, revealing a basic understanding between them. The results reveal that the reliability index is inversely related to the oversupply index, while directly related to the system self-sufficiency index. The cost of energy is more sensitive to technical indicators rather than the storage cost and so can be used as a primary monetary index. Energy and cost balance analysis showed that 16%-20% of the used energy was drained in RES operational losses, which were usually ignored in previous studies.

“…The water in the lower reservoir is transported to the higher region and stored as potential energy at the upper part. 15 The illustration of the PHES system is given in Figure 4 . In PHES technology, the low complexity of working and maintenance price is the main reason for low operation cost.…”

In this study, the effect of the COVID‐19 pandemic on electrical energy storage technologies was investigated. The results of the crises and opportunities created by this unpredictable epidemic in the future processes were evaluated according to energy and especially electrical energy storage areas. Home quarantines used to reduce the spread of the epidemic significantly increased the electrical energy needs of home users. In addition, great changes have occurred in public transportation habits during the COVID‐19 pandemic, and it has been observed that approximately 20% of individuals may prefer electric micromobility devices working with lithium batteries due to the risk of infection in closed areas such as public buses or metros. Although the demand for main energy sources has decreased significantly during the COVID‐19 pandemic, it is important that the percentage of energy produced from renewable energy sources increases by about 1%. With the increasing use of renewable energy sources and the increasing importance of the concept of sustainability in all areas of our lives, energy storage systems compatible with renewable energy technologies will become more and more important. At the beginning of these technologies, hydroelectric energy storage systems with closed‐loop pumps are preferred for large‐scale applications.

In this study, the benefits and challenges of existing energy storage systems are presented. The environmental threats and the apparent unreliability of fossil fuel energy sources necessitate the need for alternative sources of electrical power. Energy storage has been sourced from mechanical, electrical, thermal, chemical, and electrochemical systems. Perhaps, an electrochemical energy storage system, is a better option toward achieving a net zero carbon‐dioxide emission by 2050. Energy storage sources, such as: batteries and supercapacitors, can be reliably fabricated from the hybrid of polymers and two‐dimensional materials for electric vehicles, aviation, and grid load balancing applications. The performances of lithium‐ion batteries are yet to meet the requirements for high‐duty machines and devices. Graphite, the anode of lithium‐ion batteries, suffers from low capacity and high volume‐expansion, resulting in cracking and fracture of the electrodes. Herein, based on evidence from literature, this study suggests substituting graphite with polymer nanocomposite or metal‐oxide nanocomposites such as: conducting polymers, copper oxide, and graphene. This approach, giving attention to these materials' excellent electrochemical, thermal, electrical, mechanical, and redox properties, offers possible ways to overcome the limited limitations confronting lithium‐ion battery technology.
