Selected Aspects of Sustainable Mobility Reveals Implementable Approaches and Conceivable Actions

Abstract

The transportation sector plays a prominent role in driving the economy of any given nation. However, with the recent tensions arising in and around the transportation sector, sustainable mobility concepts have evolved. However, it is quite unclear whether sustainable mobility is feasible and exhibits economic returns, environmental benefits, and societal advantages. Hence, taking into account the environmental, economic, and social impact, and technical possibilities, this study intends to analyse sustainable mobility in relation to economic returns, environmental benefits and societal advantages using bibliometric analysis. For this study, we considered two decades of research, from 2001 to 2021. An in-depth search was performed on articles generated in the last two decades to assess the state of the literature on sustainable mobility. The most reverent, frequently referenced papers and influential journals in the field of sustainable mobility were identified. The acquired findings highlight the most prominent publications, journals, and authors who have made significant contributions to sustainable mobility studies, as well as the sub-areas or themes linked to sustainable mobility. Overall, the analysis discovered current paradigms, significant research topics, and a relationship between the domains of sustainable mobility studies. Meanwhile, this study also demonstrates advancements in the primary themes and sub-areas during the previous 20 years and alterations in future research fields. In addition, this study identified the promotion of rapid-reliable-safe-convenient (RRSC) transportation services, reduction in urban car traffic, and support to low transportation demand as the critical steps that require immediate attention in order to build a sustainable mobility future. We also observed that hydrogen would be a promising fuel and potential technology for the future mobility sector in the post-COVID era.

Hydrogen Fuel for Future Mobility: Challenges and Future Aspects

“…Looking at the driver experience, driving an electric car still causes range anxiety to the users that can fear that their vehicles do not have enough autonomy to reach the next charge point [32]. This is mainly due to the low range autonomy that generally affects most current BEVs on the market and the limited available charging infrastructures in many countries [33].…”

A Critical Assessment on Functional Attributes and Degradation Mechanism of Membrane Electrode Assembly Components in Direct Methanol Fuel Cells

“…Poly(3,4-ethyl) (PEDOT) backed with carbon-supported Pt is used as anode catalysts for DMFC methanol oxidation which exhibits high mass activity and superior stability after 500 durability cycles, which is greater than those of commercial Pt/C catalyst [186]. A study demonstrated a dual-template approach to produce well-defined cage-bell nanostructures containing Pt core and a mesoporous PtM (M 1 4 Co, Ni) bimetallic shell (Pt@mPtM (M 1 4 Co, Ni) CB). The unique nanostructure and bimetallic properties of Pt@mPtM (M 1 4 Co, Ni) CBs showed higher catalytic activity, superior durability, and greater CO tolerance for the methanol oxidation reaction than commercial Pt/C [187].…”

“…Accelerated climate change and environmental degradation are being suffered globally due to the widespread use of fossil fuels [1]. Fuel cells fall under the category of potential reliable energy systems [2], as most of the renewable energy systems suffer due to their intermittent operational nature [3].…”

“…The methanol and water react electrochemically and generate protons, electrons, and CO 2 at the anode, due to the methanol oxidation at the CL, as given in Equation (1). The membrane (Nafion ® ) conducts protons to the cathode and impede the electrons since the membrane is ionically conductive.…”
