“…Regarding energy TTW and vehicle operation emissions, the values obtained in the literature [38][39][40][41][42][43][44][45][46][47][48][49][50][51][52][53][54][55][56] are compared in Tables 3 and 4 with the automotive emission standards depicted in Table 2. 2 EU and US standards.…”

“…For example, vehicle manufacturing cycle GHG emissions are the highest for BEVs: 7 to 10.5 in tons of CO 2 equivalents, depending on mileage (160 to 480 km), and the lowest for gasoline ICEVs: 6.2 [37]. The performance of the various types of vehicles (ICEVs, HEVs, PHEVs, and BEVs) in terms of mileage, energy/fuel/electricity consumption, and battery energy storage is analyzed in [43] from 2011 to 2021. Both fuel/electricity consumption and battery energy storage have grown during this interval.…”

“…While BEVs charged with clean energy (RES) are the most promising in terms of reduced TTW and vehicle operation emissions, the purchase price of BEVs can represent a serious impediment, being at least EUR 5000 more expensive than an ICEV with the same weight. Figure 3 presents the life cycle costs of a compact to mid-sized car (1.3 to 1.5 tons) for all five car types, while Figure 4 refers to large-sized cars (2 to 2.5 tons) [38,39,43,50]. Various studies have provided comprehensive analyses in a similar fashion [44][45][46][47][48] but with more emphasis on the stages of the complete life cycle: WTT, TTW, and vehicle LC (including vehicle manufacturing, maintenance, and EoL), as shown in Figure 2.…”

Compared to conventional passenger cars, the hybrid and electric alternatives include electric motors and large batteries; the use of clean energy, reduced operation emissions, and decreasing purchase prices can represent solid reasons for their market adoption. The feasibility of the transition to electric cars is analyzed herein in terms of the costs, main pollutants, and energy consumption of compact to large-sized cars. In this regard, the proposed life cycle assessment methodology evaluates the pollution and energetic impacts of the current passenger car models with a weight varying from 1.6 to 1.8 tons, depending on the car type, for a complete life cycle. The life cycle emissions and energy consumption are also determined through simulation in order to validate the estimated values for the considered powertrains. This study has shown that a transition to current full-electric passenger cars, based on a European and United States energy mix, is not currently sustainable in terms of energy consumption. The complete life cycle values are similar for the tested conventional and full-electric passenger cars, ranging from 5 to 5.2 MJ/km. By comparison, the hybrid alternatives and full-electric cars based solely on renewable energy present lower energy consumption, ranging from 3.32 to 4.62 MJ/km. At the same time, the hybrid alternatives and conventional cars provide relevant benefits in life cycle costs: 20–25% lower than full-electric cars. In terms of life cycle emissions, the tested full-electric cars based on renewables show a noticeable reduction in greenhouse gases and in other relevant pollutants: 37% and 62%, respectively, lower than that of conventional cars.

“…In order to alleviate the depletion of fossil energy and reduce greenhouse gas emissions, countries around the world are vigorously promoting new energy vehicles [1][2][3][4]. New energy vehicles usually use lithium-ion batteries for electric drive, yet challenges such as short cruising range caused by low battery capacity require urgent solutions.…”

Silicon (Si) anode is a promising anode material for lithium ion batteries as its high theoretical speci c capacity. However, the commercial application of Si anode faces signi cant challenges, primarily stemming from its substantial volume change (> 300) and associated high costs. In this work, porous silicon was prepared by etching low-cost micron-sized aluminum-silicon alloy with hydrochloric acid. Subsequently, carbon-coating the porous silicon through the pyrolysis of phenolic resin, prepare a carboncoated porous silicon-carbon (Si/C) anode material. This process is not only characterized by its simplicity and cost-effectiveness, but the porous Si/C anode structure relieves the mechanical stress of the material and inhibits the expansion, powdering of silicon and the erosion of the electrolyte. The results show that the Si/C anode sintered at 800°C exhibits optimal performance. Speci cally, the Si/C anode material presented a rst discharge speci c capacity of 1394.4 mAh/g, with a capacity retention rate of 46.1% at 0.5 A/g. Nitrogen-doped silicon carbon composite material (Si/NC) was synthesized to further improve the performance of Si/C anodes. The characterizations con rm good crystallinity, uniform carbon coating on silicon surfaces, and even distribution of Si, C, and N elements. The Si/NC anode achieves a rst speci c capacity of 1218.3 mAh/g at 0.5 A/g, with a speci c capacity of 563.7 mAh/g after 300 cycles, and the cycle retention rate still remains 42.7%, demonstrating stable cycling of the micron-sized silicon anode.

“…Several reviews have been published about energy consumption in road transportation [6] and maritime transportation [8], just to mention some. In addition, researchers have focused on transportation advancements such as hybrid and electric cars [9,10]. Approaches such as machine learning, mathematical programming, simulation, and metaheuristics have been used intensively in optimizing the transportation sector [11].…”

On the Use of Agile Optimization for Efficient Energy Consumption in Smart Cities’s Transportation and Mobility

Urban logistics consumes a large portion of energy resources worldwide. Thus, optimization algorithms are used to define mobility modes, vehicle fleets, routing plans, and last-mile delivery operations to reduce energy consumption such as metaheuristics. With the emergence of smart cities, new opportunities were defined, such as carsharing and ridesharing. In addition to last-mile delivery, these opportunities form a challenging problem because of the dynamism they possess. New orders or ride requests could be placed or canceled at any time. Further, transportation times might evolve due to traffic conditions. These dynamic changes challenge traditional optimization methods to propose solutions in real-time to large-scale energy-optimization problems. Thus, a more `agile optimization’ approach is required to provide fast solutions to optimization problems when these changes occur. Agile optimization combines biased randomization and parallelism. It provides `good’ solutions compared to solutions found by traditional optimization methods, such as in-team orienteering problems. Additionally, these solutions are found in short wall clock, real-time.
