“…This demonstrates that coupling electrolysis with clean electricity is a key element to achieve greater results in terms of the environmental impact reduction in hydrogen-powered vehicles. The results obtained from the environmental analysis were coherent with other studies that estimated the life cycle CO 2 emissions of fuel cell vehicles to be less than 50% of that of the traditional counterpart, with very low-use phase impacts when hydrogen is produced from renewables [62][63][64].…”

The growing awareness about climate change and environmental pollution is pushing the industrial and academic world to investigate more sustainable solutions to reduce the impact of anthropic activities. As a consequence, a process of electrification is involving all kind of vehicles with a view to gradually substitute traditional powertrains that emit several pollutants in the exhaust due to the combustion process. In this context, fuel cell powertrains are a more promising strategy, with respect to battery electric alternatives where productivity and endurance are crucial. It is important to replace internal combustion engines in those vehicles, such as the those in the sector of Non-Road Mobile Machinery. In the present paper, a preliminary analysis of a fuel cell powertrain for a telehandler is proposed. The analysis focused on performance, fuel economy, durability, applicability and environmental impact of the vehicle. Numerical models were built in MATLAB/Simulink and a simple power follower strategy was developed with the aim of reducing components degradation and to guarantee a charge sustaining operation. Simulations were carried out regarding both peak power conditions and a typical real work scenario. The simulations’ results showed that the fuel cell powertrain was able to achieve almost the same performances without excessive stress on its components. Indeed, a degradation analysis was conducted, showing that the fuel cell system can achieve satisfactory durability. Moreover, a Well-to-Wheel approach was adopted to evaluate the benefits, in terms of greenhouse gases, of adopting the fuel cell system. The results of the analysis demonstrated that, even if considering grey hydrogen to feed the fuel cell system, the proposed powertrain can reduce the equivalent CO2 emissions of 69%. This reduction can be further enhanced using hydrogen from cleaner production processes. The proposed preliminary analysis demonstrated that fuel cell powertrains can be a feasible solution to substitute traditional systems on off-road vehicles, even if a higher investment cost might be required.

“…Specifically, coal, oil, and natural gas accounted for 56.0%, 18.5%, and 8.9%, respectively [6]. The biggest drawback of fossil fuels is the air pollutant emissions, of which greenhouse gas (GHG) emissions are considered to be a major contributor to global warming [17]. The transport sector accounts for about 20% of the total global primary energy consumption and about 23% of CO 2 emissions, and when emissions of other GHGs such as methane are taken into account, these account for about 14% of total global GHG emissions or about 7 billion tons of CO 2 equivalent, almost the same as the livestock sector [18].…”

“…Therefore, decarbonization of the transportation sector is more challenging than in other sectors. The use of clean alternative energy sources is one effective way to address this challenge, and it has been studied by scholars in recent years [17,18]. Hydrogen is a promising renewable energy source, which attracts people's attention because of its clean and abundant properties [19].…”

Global energy and environmental issues are becoming increasingly serious, and the promotion of clean energy and green transportation has become a common goal for all countries. In the logistics industry, traditional fuels such as diesel and natural gas can no longer meet the requirements of energy and climate change. Hydrogen fuel cell logistics vehicles are expected to become the mainstream vehicles for future logistics because of their “zero carbon” advantages. The GREET model is computer simulation software developed by the Argonne National Laboratory in the USA. It is extensively utilized in research pertaining to the energy and environmental impact of vehicles. This research study examines four types of logistics vehicles: hydrogen fuel cell vehicles (FCVs), electric vehicles, LNG-fueled vehicles, and diesel-fueled vehicles. Diesel-fueled logistics vehicles are currently the most abundant type of vehicle in the logistics sector. LNG-fueled logistics vehicles are considered as a short-term alternative to diesel logistics vehicles, while electric logistics vehicles are among the most popular types of new-energy vehicles currently. We analyze and compare their well-to-wheels (WTW) energy consumption and emissions with the help of GREET software and conduct lifecycle assessments (LCAs) of the four types of vehicles to analyze their energy and environmental benefits. When comparing the energy consumption of the four vehicle types, electric logistics vehicles (EVs) have the lowest energy consumption, with slightly lower energy consumption than FCVs. When comparing the nine airborne pollutant emissions of the four vehicle types, the emissions of the FCVs are significantly lower than those of spark-ignition internal combustion engine logistics vehicles (SI ICEVs), compression-ignition direct-injection internal combustion engine logistics vehicles (CIDI ICEVs), and EVs. This study fills a research gap regarding the energy consumption and environmental impact of logistics vehicles in China.

“…A large amount of hazardous gas SOx will be discharged into the atmosphere during the use of automotive fuels, such as gasoline and diesel because of the high sulfur content. − Sulfides are easy to poison the catalysts used for vehicle exhaust purification, further increasing the emission of toxic gases such as NOx and CO. , Therefore, all countries in the world have formulated strict emission standards to limit the sulfur content of automotive fuels − of which the VI fuel standards in China limit the sulfur mass fraction of automotive gasoline and diesel to no more than 10 mg/kg. Since gasoline and diesel produced by FCC process are the main sources of automotive fuels and the sulfur content is usually high, , it is of practical significance to understand the formation mechanisms and conversion paths of sulfides in the FCC, gasoline hydrotreating, and diesel hydrotreating processes.…”

To meet the requirements of fuel standards, the coupling simulations of fluid catalytic cracking (FCC) and hydrotreating processes were carried out to analyze the conversion and distribution of sulfides at the molecular level to improve the cleanliness of gasoline and diesel. According to the structure-oriented lumping (SOL) method and the reaction mechanism, the transformation laws and distributions of sulfides in gasoline and diesel were studied. When the FCC reaction temperature increased, the content of dimethyl-thiophene in heavy gasoline and the content of dimethyl-dibenzothiophene in diesel increased due to the stronger promotion of high temperature to the side chain cracking reactions. As gasoline hydrotreating reaction temperature rose from 220 to 280 °C, the content of dimethyl-thiophene in heavy gasoline reduced from 4.77 to 0.98 mg/kg since higher temperature promotes the hydrodesulfurization reactions. The coupling simulation could provide effective guidance at the molecular level for reducing the content of sulfides in heavy gasoline and diesel.
