“…When hydrogen produced from natural gas reforming is used as a fuel, it can reduce WTW fossil energy consumption by 5-33% and WTW GWP by 15-45% [90]. However, as technology changes, the advantages of hydrogen production from natural gas gradually decrease [171], and the energy efficiency of hydrogen production from natural gas is low [172]. This makes hydrogen production from natural gas no longer stable, especially while the database is not unified, and high uncertainty and inaccuracy appear [22,90].…”

New energy vehicles (NEVs), especially electric vehicles (EVs), address the important task of reducing the greenhouse effect. It is particularly important to measure the environmental efficiency of new energy vehicles, and the life cycle analysis (LCA) model provides a comprehensive evaluation method of environmental efficiency. To provide researchers with knowledge regarding the research trends of LCA in NEVs, a total of 282 related studies were counted from the Web of Science database and analyzed regarding their research contents, research preferences, and research trends. The conclusion drawn from this research is that the stages of energy resource extraction and collection, carrier production and energy transportation, maintenance, and replacement are not considered to be research links. The stages of material, equipment, and car transportation and operation equipment settling, and forms of use need to be considered in future research. Hydrogen fuel cell electric vehicles (HFCEVs), vehicle type classification, the water footprint, battery recovery and reuse, and battery aging are the focus of further research, and comprehensive evaluation combined with more evaluation methods is the direction needed for the optimization of LCA. According to the results of this study regarding EV and hybrid power vehicles (including plug-in hybrid electric vehicles (PHEV), fuel-cell electric vehicles (FCEV), hybrid electric vehicles (HEV), and extended range electric vehicles (EREV)), well-to-wheel (WTW) average carbon dioxide (CO2) emissions have been less than those in the same period of gasoline internal combustion engine vehicles (GICEV). However, EV and hybrid electric vehicle production CO2 emissions have been greater than those during the same period of GICEV and the total CO2 emissions of EV have been less than during the same period of GICEV.

“…Based on the study's findings, for the FC vehicle employing hydrogen to be competitive regarding GHG emission and energy consumption, its efficiency must be higher than gasoline by 25-30%. In another study, Evtimov et al [34] used an LCA to evaluate fuel-cell electric vehicle (FCEV) efficiency using various hydrogen production technologies. The study compared the fuel consumption and GHG emissions over the entire life of conventional gasoline vehicles and FCEVs.…”

Proton-exchange membrane fuel cells (PEMFCs) are highly regarded as a promising technology for renewable energy generation; however, the environmental burden in their life cycle is a subject of concern. This study aimed to assess the environmental impact of producing a 1 kW PEMFC by a well-detailed cradle-to-gate evaluation, using mid-point and end-point impact assessment methods. The environmental impacts are related to the extraction of raw materials, consumption of energy, and transportation processes. Mid-point analysis shows that raw materials extraction and processing have a significant share in some impacts, including freshwater eutrophication, human carcinogenic toxicity, and terrestrial acidification. On the other hand, the energy consumed in fuel cell production plays a significant role in the impact categories of fossil resource depletion and global warming. The highest impact is attributed to the human health end-point analysis (0.000866 DALY), followed by the damage to ecosystems (1.04 × 10−6 species/yr) and resources (USD2013 6.16844). Normalization results further strengthen the importance of human health impacts and the necessity to solve problems regarding toxicity. The results of this work can provide directions toward enhancing the environmental sustainability of PEMFC technology and present a case for adopting a holistic approach to sustainability by looking across the life cycle of the technology.

Industry, especially the automotive industry is permanently changing and adapting to the external and internal factors. The appearance of the new types of vehicles – electric vehicles, is a big and important step not only regarding the evolution of the product, but also regarding the advantages of reducing environmental impact. It is promoted the idea that an electric vehicle generates less direct emissions in use phase compared with a conventional one. If we limit to this, we could say that we are dealing with an eco-friendly type of vehicle. The question is, can we extend this idea to the other stages of the life cycle? What about the sustainability of the industry? This article highlights the methods of environmental impact assessment used by researchers for electric vehicles in terms of life cycle and sustainability. The findings of this systematic review demonstrate that even if are a large number of articles addressing electric vehicles, only a small number of them evaluate the electric vehicle from life cycle and sustainability point of view.
