Furthermore, even in the case of conventional electrical energy generation from non-renewable sources, for transfer to the consumers in household, factories, and so on, via power grid, energy storage is essential to store energies at times when production exceeds consumption and use the stored energy during the reverse scenario. This improves the grid stability by leading to improved load levelling (i.e., utilizing surplus energy generated during “on hours” and during the “off hours” of the sources), peak shaving (i.e., accommodating “peaks” and “valleys” in the daily demand curve), and system regulation (i.e., addressing short-term/random fluctuations in demand without the need for regulation by the main or harvesting/supplying plant). In a way, the large-scale grid energy storage leads to overall improvement in the quality and reliability of the power used in household, as well as in industry; irrespective of the fact whether the electricity gets produced by a renewable/green or non-renewable source.
Peripheral Energy Markets

Grid energy storage is large-scale storage of electrical energy, using the resources of the national electric grid, which allows energy producers to send excess electricity over the electricity transmission grid to temporary electricity storage sites that become energy producers when electricity demand is greater. Grid energy storage is a very efficient storage method, playing an important role in leveling and matching electric power supply and demand over a 24-hour period.

Grid energy storage is large-scale storage of electrical energy, using the resources of the national electric grid, which allows energy producers to send excess electricity over the electricity transmission grid to temporary electricity storage sites that become energy producers when electricity demand is greater. Grid energy storage is a very efficient, albeit limited, storage method, which could play an important role in leveling and matching electric power supply and demand over a 24hour period.

Battery repurposing is a process to give old batteries with a specific state of health (SOH) and level of charge a second chance. The reuse of portable batteries has been going on for a while now, mostly unnoticed by the general public. Batteries from EV, which have taken over as the market leader for lithium, continue to be utilized in a variety of applications after they have reached their end of life. The self-life of LIBs used in electric cars is less than 10 years (Foster et al., 2014). The power produced by the batteries will not be adequate for an EV to reach the target range after 7 to 8 years of continuous use. Therefore, these batteries, having medium range of capacity (70–80%), can be used for other second life application and can function for several years (DeRousseau et al., 2017). The major applications of these re-used batteries include: electric power back-up in residential or commercial;power-grid energy storage;and energy storage in renewable energy storage system.

During battery recycling, the waste generated from NEVs takes different recycling routes: LIBs second use (LIBs2U; Li et al. 2018) and materials recycling. LIBs2U which is associated with a high energy demand, where spent LIBs usually retain 80% of their original electric capacity (Williams and Lipman 2010). Currently, the feasibility of the LIBs2U approach has been explored regarding the associated economic, technological, and ecological factors (Li et al. 2018). It has presented the primary practice of grid energy storage6 as energy back-up in telecom tower bases (Pagliaro and Meneguzzo 2019). In terms of materials recycling, systematic physical and chemical methods have been adopted in the recycling process for repurposing spent metals or materials (Du et al. 2022; Huang et al. 2018). Parts of the spent LIBs, such as their cathodes and anodes, can be used in the recycling process (Du et al. 2022; Liang et al. 2019; Natarajan and Aravindan 2020). However, no studies to date have focused on calculating the amount of generated spent LIBs or the economic potential associated with the valuable metals (e.g., cobalt, nickel, and lithium) contained in the spent NEV LIBs.
ANFIS Based Energy Management System for V2G Integrated Micro-Grids

The number of electric vehicles (EVs) is expected to increase significantly in the coming years reflecting their potential to reduce air pollutants and greenhouse gas emissions [1]. It has been revealed by some studies that most personal transportation vehicles are parked almost 95% of their time [2]. In this scenario, EVs can remain connected to the grid and deliver energy stored in their batteries under the concept of vehicle-to-grid (V2G) technology introduced in [3]. V2G allows bidirectional energy exchange between EVs and the power grid, which offers numerous services to the power grid, such as regulation, spinning reserves, peak load shaving, load leveling and reactive power compensation [4]. As V2G begins to saturate these high value markets, it was concluded in [5] that it will be positioned to play a more fundamental role of energy storage in modern power grids, which are primarily based on intermittent renewable energy sources (RES). In this context, EVs can be utilized as potential energy storage devices in micro-grids. EV batteries can reduce the investment cost of micro-grid energy storage systems (ESS), which is currently the main obstacle for their diffusion. An aggregator is not required in this case as the micro-grid power demand will be generally small enough to be met from the EVs of a single parking lot.
