“…PV off-grid charging stations are more feasible as compared to wind-based energy because of fewer conversion stages to generate power [339]. Research [340] designed an off-grid PV charging station by assessing the life cycle assessment. Researchers in [341] designed a stochastic planning model formulated as multi-objective linear programming for green stand-alone charging stations powered entirely by RESs.…”

Electrical power systems with their components such as generation, network, control and transmission equipment, management systems, and electrical loads are the backbone of modern life. Historical power outages caused by natural disasters or human failures show huge losses to the economy, environment, healthcare, and people’s lives. This paper presents a systematic review on three interconnected dimensions of (1) electric power system resilience (2) the electricity supply for/through Electric Vehicles (EVs), and (3) social vulnerability to power outages. This paper contributes to the existing literature and research by highlighting the importance of considering social vulnerability in the context of power system resilience and EVs, providing insights into addressing inequities in access to backup power resources during power outages. This paper first reviews power system resilience focusing on qualitative and quantitative metrics, evaluation methods, and planning and operation-based enhancement strategies for electric power systems during prolonged outages through microgrids, energy storage systems (e.g., battery, power-to-gas, and hydrogen energy storage systems), renewable energy sources, and demand response schemes. In addition, this study contributes to in-depth examination of the evolving role of EVs, as a backup power supply, in enhancing power system resilience by exploring the EV applications such as vehicle-to-home/building, grid-to-vehicle, and vehicle-to-vehicle or the utilization of second life of EV batteries. Transportation electrification has escalated the interdependency of power and transportation sectors, posing challenges during prolonged power outages. Therefore, in the next part, the resilient strategies for providing electricity supply and charging services for EVs are discussed such as deployments of battery swapping technology and mobile battery trucks (MBTs), as well as designing sustainable off-grid charging stations. It offers insights into innovative solutions for ensuring continuous electricity supply for EVs during outages. In the section on social vulnerability to power outages, this paper first reviews the most socioeconomic and demographic indicators involved in the quantification of social vulnerability to power outages. Afterward, the association between energy equity on social vulnerability to power outages is discussed such as inequity in backup power resources and power recovery and restoration. The study examines the existing challenges and research gaps related to the power system resilience, the electric power supply for/through EVs, social vulnerability, and inequity access to resources during extended power outages and proposes potential research directions to address these gaps and build upon future studies.

“…The utilization of solar photovoltaic (PV) panels for recharging shared electric micro-mobility vehicles holds [16]. Other researchers also proposed prototypes of off-grid solar charging stations tailored for shared electric micromobility, with several instances undergoing successful onsite evaluations [17][18][19]. However, current studies primarily focus on solar charging stations that exclusively address a single type of micro-mobility vehicle, with relatively scant attention devoted to the exploration of mixed-mobility hubs accommodating diverse micromobility modes for integrated travel solutions.…”

“…For example, Zhu et al developed a battery-level-aware real-time shareability network of solar-charged electric scooters, reducing charging costs with 1-3 m 2 PV module at each station[16]. Other researchers also proposed prototypes of off-grid solar charging stations tailored for shared electric micromobility, with several instances undergoing successful onsite evaluations[17][18][19]. However, current studies primarily focus on solar charging stations that exclusively address a single type of micro-mobility vehicle, with relatively scant attention devoted to the exploration of mixed-mobility hubs accommodating diverse micromobility modes for integrated travel solutions.In addition, some researchers have highlighted that solar charging stations for electric shared micro-mobility must be equipped with adequate batteries to achieve completely off-grid, thereby realizing true zero-carbon operations[20,21].…”

The rapid adoption of shared electric micro-mobility solutions, such as e-scooters and e-mopeds, has addressed the need for low-carbon transportation and efficient last-mile travel. However, challenges persist due to insufficient parking and charging infrastructure. This study introduces an innovative shared electric micromobility hub prototype, incorporating PV panels to provide energy and shared power bank stations for battery storage. Through a comprehensive case study, the economic and environmental benefits of different micro-mobility configurations and energy management strategies are evaluated. The results demonstrate that the micro-mobility with appropriately configured PV and shared power bank station can reduce carbon emissions by 99% and achieve a net income within one year. This research not only advances sustainable urban transportation but also provides a model for integrating various shared services, contributing to a more environmentally friendly and versatile urban lifestyle.

“…According to the reduce, reuse and recycling concept for waste prevention by the United Nations and the proposals for the end-of-life management of PV panels by IEA and IRENA reuse is generally preferred (United Nations, 2004;Weckend et al, 2016). High savings potentials of reused PV panels in terms of greenhouse gas (GHG) emissions have been identified in case study applications (Schelte et al, 2021). However, there are many parameters to consider, and it is often unclear if recycling or reuse is the more sustainable option for individual cases.…”

This paper aims to assess the environmental and economic impact when it comes to the presumed end of life for solar photovoltaic (PV) panels. A recycling option is compared to the reuse of the PV panels in the two impact categories: costs for the consideration of economic feasibility and global warming potential (GWP 100) for the consideration of the environmental impact. The evaluation is carried out with a parametric life-cycle-assessment-based model that was designed to be adaptable for evaluating different scenarios by changing the parameters to fit the given cost structure or climate zone in which the panels are being used. The recycling option involves market-established methods for recycling the old panels and replacing them with new ones. The reuse case involves testing and reusing the old panels, taking a certain rejection rate into account. The most significant parameters for the reduction of greenhouse gas emissions are the rejection rate, the solar radiation and thus the capacity utilization as well as the expected lifetime of the newly manufactured panels and their greenhouse gas emissions during production. The results indicate that in most cases greenhouse gas emissions can be saved compared to the recycling option. The costs for reuse compared to recycling depend on the rejection rate and the expected lifetime for both the panels, that can be reused and the new panels. The comparison of the costs for reuse and recycling contains some uncertainties since the testing of panels has yet to be commercially established and automized. The model developed in this paper allows for the holistic evaluation of individual reuse and recycling scenarios. The results can thus be used to determine decision-making for better economic and environmental outcomes.
