“…In the urban transportation (private cars, taxis, buses, and urban rail transit), the energy consumption of various options is different, with private cars having the highest energy consumption. The rapid development of the private cars industry has an adverse influence on the energy scenario and environment of the cities (Chang, Ma, and Wu 2018). Road vehicles consume approximately 50% of the world's oil produced (Balat 2008).…”

Hydrogen has the potential to be the sustainable fuel of the future, decrease the global dependence on fossil fuel resources, and lower the pollutant emissions from the transportation industry. In this study, recent development in hydrogen-based transportation engines is reviewed to scrutinize the feasibility of using hydrogen as a major fuel of future. Using hydrogen in internal combustion engines achieves only 20-25% efficiency and low power output compared to fossil-fueled internal combustion engines. Although hydrogen-based internal combustion engines have recently received considerable interests, several practical barriers have prevented the fast development of this technology. Hence, at the current stage, using hydrogen as an additive to hydrocarbon fuel systems have been taken into consideration to produce higher performance than hydrogen-only internal combustion engines. Using the dual-fuel strategy can increase the combustion stability and thermal efficiency while decreasing the CO and unburned hydrocarbons emissions, and fuel consumption. Alternatively, hydrogen can be used in fuel cells for vehicular applications with several automotive manufacturers producing fuel cell vehicles currently. Fuel cells can achieve efficiencies of up to 60%, while the rest is lost as heat. Strategies that have been investigated to increase the efficiency, performance, and lifespan of fuel cells are capillary pumping systems, a chemisorption chiller, nanofluids and supercapacitors. All such strategies improved the fuel cells in one or more ways. Safety, hydrogen delivery, onboard storage, and the capital and operating costs of hydrogen powered vehicles are analyzed to approach to clean transportation utopia.

“…The US Department of Energy predicts that the cost of producing hydrogen power will continue to fall from $6 kg −1 in 2015 to $2 kg −1 by 2025, which is motivating. Several studies in the literature have further discussed the political challenges and the progress considering the urbanisation, economics, role, and involvement of industry as well as marketing strategies [4,[6][7][8][21][22][23][24][25][26][27]. Particularly, ongoing activities in the field of climate change, implementation of fuel cell technology, and urbanisation and public investments [28][29][30][31][32][33] are depicted.…”

“…The emissions of the Chinese industrial sector alone, for instance comprises 24.1% of global emissions [2], which proves its great relevance to the global climate policy. Thus, there have been tremendous efforts in research to contribute to climate neutral strategies [2][3][4][5][6][7][8][9][10][11][12]. Decarbonisation processes such as the storage of CO 2 in biological or geological means (such as negative emissions technologies or greenhouse gas removal) as well as solar radiation management techniques to reflect back the sunlight into space are also widely used [13].…”

The popularity of climate neutral new energy vehicles for reduced emissions and improved air quality has been raising great attention for many years. World-wide, a strong commitment continues to drive the demand for zero-emission through alternative energy sources and propulsion systems. Despite the fact that 71.27% of hydrogen is produced from natural gas, green hydrogen is a promising clean way to contribute to and maintain a climate neutral ecosystem. Thereby, reaching CO2 targets for 2030 and beyond requires cross-sectoral changes. However, the strong motivation of governments for climate neutrality is challenging many sectors. One of them is the transport sector, as it is challenged to find viable all-in solutions that satisfy social, economic, and sustainable requirements. Currently, the use of new energy vehicles operating on green sustainable hydrogen technologies, such as batteries or fuel cells, has been the focus for reducing the mobility induced emissions. In Europe, 50% of the total emissions result from mobility. The following article reviews the background, ongoing challenges and potentials of new energy vehicles towards the development of an environmentally friendly hydrogen economy. A change management process mindset has been adapted to discuss the key scientific and commercial challenges for a successful transition.
