Summary: Electric shared micromobility, specifically China's free-floating e-bike sharing, has seen widespread adoption and development globally. However, its environmental impact is not well understood. A life cycle assessment study was conducted to quantitatively estimate the environmental impacts of FFEBS, including human health, ecosystems, and resources, based on user travel behavior and operational data. The study found that the low utilization of FFEBS makes it an environmentally unfriendly mode of transportation, and significant improvements are needed to achieve environmental benefits.

Summary: This research investigates the impact of different charging conditions on carbon footprints, including dynamic on-road charging through an electric road system (ERS). The study uses a prospective life cycle analysis framework to estimate carbon footprints of vehicles, fuels, and infrastructure, and models vehicle stock turnover and optimal battery capacity based on Swedish real-world driving patterns. The findings suggest that implementing ERS on selected high-traffic roads, combined with stationary charging, can significantly reduce carbon emissions, even if only a small percentage of vehicles adopt optimized battery capacities.

Summary: The use of electric vehicles aims to reduce carbon emissions and environmental pollution caused by transportation. However, the production and application of electric vehicle batteries also contribute to environmental pollution. Research shows that LiFePO4 batteries are more environmentally friendly in the production phase, while Li(NiCoMn)O-2 batteries are more eco-friendly in the application and transportation phases. Despite this, LiFePO4 batteries are generally more environmentally friendly than Li(NiCoMn)O-2 batteries over their entire life cycle.

Summary: The transportation industry is using autonomous electric vehicles (A-EVs) to combat climate change and reduce air pollution. A-EVs, equipped with artificial intelligence and next-generation batteries, are expected to replace traditional internal combustion engine vehicles and electric vehicles (EVs) in the near future. A life cycle assessment was performed to analyze the impacts of A-EVs compared to EV and ICEV systems. The study found that A-EVs have higher impacts in the manufacturing phase due to additional components, while in the use phase, A-EVs outperform EV and ICEV systems in terms of global warming potential, acidification, and smog formation. The use of A-EVs in regions with hydropower-based electricity grids was identified as the most environmentally friendly option.

Summary: This study examined the application of foundry sand waste materials in road construction and structural fill from ten different industries. Laboratory tests were conducted to assess the physical, chemical, and geotechnical properties. Stabilization with cement was done for two samples, and the effects of curing period and cement content on key parameters such as compressive and tensile strength were analyzed. It was found that finer samples were suitable for subbase layer construction while both samples could be used as structural fill, supporting sustainable construction practices.

Summary: This study investigates the economic feasibility of reducing and replacing emergency diesel generators with solar photovoltaic (PV) systems, battery energy storage systems (BESS), and demand-side management. The optimal configuration and scheduling of new assets are determined using a mixed-integer quadratically constrained program, aiming to minimize the levelized cost of energy (LCOE). The results for a hospital and its surrounding community in Gulu, Uganda, show that full replacement of the diesel generators requires additional PV capacity and BESS, leading to a 26% decrease in LCOE, a simple payback time of 6.2 years, and a 74% reduction in greenhouse gas emissions.

Summary: The increasing use of electric vehicles presents challenges for the electricity system's energy, power, and balance adequacy. This paper proposes a methodology to simulate charging demand for different types of drivers in a local energy system, using time series of charging sessions. The methodology extracts driver types from historical charging session data and characterizes them through kernel density estimation. The results demonstrate that the methodology accurately captures the stochastic nature of drivers' charging behavior, allowing for future demand scenarios and assessment of smart charging benefits.

Summary: Decentralized energy systems with renewable generation and electric storage can integrate electricity more effectively and reduce greenhouse gas emissions. However, the environmental impacts of such systems are still not well studied. This research conducted a life cycle assessment of decentralized energy generation and storage technologies in Belgium for 2030 and 2050. Results show a decrease in CO2 emissions and land use impacts, but an increase in mineral resource scarcity and terrestrial ecotoxicity. Sensitivity analysis indicates solar irradiation as the most influential parameter. Further research on end-of-life strategies for photovoltaic installations and batteries is suggested to reduce environmental impacts.

Summary: This study evaluates the second life of a NMC-LTO battery through a multidisciplinary approach and demonstrates that these batteries are suitable for reuse or repurposing. The life cycle assessment shows that the second life of the battery is beneficial for climate change under certain conditions. Reuse reduces the impact on climate change, especially in countries with a lower electricity mix. Repurposing the battery also reduces the impact on climate change and acidification.
