“…Additionally, 27% of the case studies accounted for on-site hydrogen production processes (97/355), including on-site thermochemical processes (41/97) and on-site electrochemical processes (56/97). However, only five case studies addressed on-board auto thermal reforming [65]. Moreover, only 9% of the total centralized thermochemical case studies (13/140) involved carbon capture and sequestration (CCS), and considered SR and gasification [35,36,46,56,62,67,71,84].…”

“…Most studies (252) used in this review did not specify the fuel cell type. PEMFC technology was explicitly mentioned for hydrogen use in 36 case studies [21-23, 27, 29, 38, 44, 56, 61, 70], and only five case studies considered SOFCs [65]. As shown in the 'hydrogen use for road transport' stage in figure 5, four types of powertrains were considered for cars: FCV (175/230), FCHEV (9/230), ICEV (34/230), and HICEV (7/230).…”

“…Buses were observed in two powertrain types (FCV (17/19) and FCHEV (2/19)), while only FCV (18) was discussed for motorcycles. Furthermore, LCA studies of different hydrogen pathways that operated in the FCV in the WTW stage were compared [25,27,33,36,39,40,42,43,46,51,55,65,72]. Other WTW studies compared different hydrogen pathways in ICEVs [6,49].…”

This study conducted a systematic literature review of the technical aspects and methodological choices in life cycle assessment (LCA) studies of the use of hydrogen for road transport. More than 70 scientific papers published during 2000–2021 were reviewed, in which more than 350 case studies of the use of hydrogen in the automotive sector were found. Only some studies used hybrid LCA and energetic input–output LCA, whereas most studies addressed attributional process-based LCA. A categorization based on the life cycle scope distinguished case studies that addressed the well-to-tank (WTT), well-to-wheel (WTW), and complete life cycle approaches. Furthermore, based on the hydrogen production process, these case studies were classified into four categories: thermochemical, electrochemical, thermal–electrochemical, and biochemical. Moreover, based on the hydrogen production site, the case studies were classified as centralized, on-site, and on-board. The fuel cell vehicle passenger car was the most commonly used vehicle. The functional unit for the WTT studies was mostly mass or energy, and vehicle distance for the WTW and complete life cycle studies. Global warming potential (GWP) and energy consumption were the most influential categories. Apart from the Greenhouse Gases, Regulated Emissions, and Energy Use in Transportation model and the Intergovernmental Panel on Climate Change for assessment of the GWP, the Centrum voor Milieukunde Leiden method was most widely used in other impact categories. Most of the articles under review were comparative LCA studies on different hydrogen pathways and powertrains. The findings provide baseline data not only for large-scale applications, but also for improving the efficiency of hydrogen use in road transport.

“…Based on the literature, different sources of hydrogen production such as electrolysis, biomass gasification, steam methane reforming, and coal gasification are studied here [49]. GHG emission factors for hydrogen production from various methods are given in Table 5 [50]. The impact of these sources on the overall life cycle GHG emissions is shown in Figure 4.…”

This case study investigates the potentials, greenhouse gas (GHG), and energy performance of forest residue biofuels produced by new and emerging production technologies, which are commercially implemented in Sweden for heavy transport. The biofuel options included are ethanol (ED 95), hydro-processed vegetable oil (HVO), and liquefied biogas (LBG) produced from logging residues in forestry and sawdust generated in sawmills. The calculated life cycle GHG emissions, based on the EU Renewable Energy Directive calculation methodology, for all three pathways are in the range of 6–11 g CO2eq./MJ, corresponding to 88–94% GHG emission reductions as compared to fossil fuel. Critical parameters are the enzyme configuration for ethanol, hydrogen supply systems and bio-oil technology for HVO, and gasifier size for LBG. The energy input is ranging from 0.16 to 0.43 MJ/MJ biofuel and the total conversion efficiency from the feedstock to biofuel, including high-value by-products (excluding heat), varies between 61 and 65%. The study concludes that the domestic biofuel potential from estimated accessible logging residues and sawdust is equivalent to 50–100% of the current use of fossil diesel in heavy-duty road transport in Sweden, depending on the biofuel production technology selected and excluding energy by-products. Thus, an expansion of forest-based biofuels is a promising strategy to meet the ambitious climate goals in the transport sector in Sweden.

“…Daniele et al [7] evaluated the life-cycle performance of three different types of vehicles based on wind power electrolysis of water for hydrogen production and the results showed that hydrogen fuel is an excellent decarbonization solution. Both Dong et al [8] and Huang et al [9] performed life cycle analysis of the environmental impact of fuel cell vehicle energy under different fossil fuel-based hydrogen fuel paths. The results showed that supplying fuel cell vehicles with hydrogen from natural gas reforming is the most advantageous in terms of energy saving and emission reduction.…”

In order to better achieve the goal of low carbon emissions from vehicles, a whole life cycle assessment of hydrogen-fueled internal combustion engine vehicles has been conducted in recent years. Based on the study of hydrogen use around the world, we studied the emission and economic performance of hydrogen-fueled internal combustion engine vehicles from the beginning of hydrogen production to the end of use (Well-to-Wheel, WTW) based on the whole life cycle evaluation method. The results show that the overall environmental impact of hydrogen production by steam reforming of natural gas is the smallest, and that the rational use of "abandoned electricity" for hydrogen production from electrolytic water in the western part of China significantly reduces the overall environmental impact and the cost of hydrogen production. In the use phase, the emissions are less, which not only can meet the National 6 emission standard, but also can reach higher emission standard after adding exhaust gas recirculation (EGR). From the whole life cycle point of view, hydrogen-fueled internal combustion engine has a very good development prospect.
