“…Different technologies are, therefore, being proposed in order to conduct thermolysis at lesser temperatures. One of such strategies involves the conduction of the reaction in a number of phases with the use of catalysts; however, the requirement of very corrosive reagents also poses challenges to equipment as well as a possible negative impact on the environment [65].…”

“…In the same way, Hsu [67] proposed a raney nickel plate reactor (10% Aluminum and 90% Nickel), which functions as a catalytic surface to change the reaction's energy activation. Additionally, iodine (I ) and sulfur dioxide (SO ) were added to the medium, which had a decreasing effect on the temperature of the reaction, as presented in Equations ( 17) and ( 18) [65]:…”

“…The dissociation of the H-O bonds by photons is known as photolysis, which occurs at about 190 nm [69]. This process and thermolysis need chemical catalysts such as ZrO2, tin oxide (SnO), zinc oxide (ZnO), and other semiconductor sulfur oxides [65] (Equations ( 19) and ( 20)):…”

An increase in human activities and population growth have significantly increased the world’s energy demands. The major source of energy for the world today is from fossil fuels, which are polluting and degrading the environment due to the emission of greenhouse gases. Hydrogen is an identified efficient energy carrier and can be obtained through renewable and non-renewable sources. An overview of renewable sources of hydrogen production which focuses on water splitting (electrolysis, thermolysis, and photolysis) and biomass (biological and thermochemical) mechanisms is presented in this study. The limitations associated with these mechanisms are discussed. The study also looks at some critical factors that hinders the scaling up of the hydrogen economy globally. Key among these factors are issues relating to the absence of a value chain for clean hydrogen, storage and transportation of hydrogen, high cost of production, lack of international standards, and risks in investment. The study ends with some future research recommendations for researchers to help enhance the technical efficiencies of some production mechanisms, and policy direction to governments to reduce investment risks in the sector to scale the hydrogen economy up.

“…Furthermore, compared to other propulsion vehicles, FCVs have unique strengths and weaknesses, as shown in Table 6 [34]. Importantly, unlike electricity generation, hydrogen production can provide a solution to the waste of renewable energy as it is suitable for large-scale electricity storage [35]. Thus, this stands as a valid alternative for future sustainable mobility.…”

Electric Mobility in Portugal: Current Situation and Forecasts for Fuel Cell Vehicles

In recent years, the growing concern for air quality has led to the development of sustainable vehicles to replace conventional internal combustion engine (ICE) vehicles. Currently, the most widespread technology in Europe and Portugal is that of Battery Electric Vehicles (BEV) or plug-in HEV (PHEV) electric cars, but hydrogen-based transport has also shown significant growth in the commercialization of Fuel Cell Electric Vehicles (FCEV) and in the development of new infrastructural schemes. In the current panorama of EV, particular attention should be paid to hydrogen technology, i.e., FCEVs, which is potentially a valid alternative to BEVs and can also be hybrid (FCHEV) and plug-in hybrid (FCPHEV). Several sources cited show a positive trend of hydrogen in the transport sector, identifying a growing trend in the expansion of hydrogen infrastructure, although at this time, it is still at an early stage of development. At the moment, the cost of building the infrastructure is still high, but on the basis of medium/long-term scenarios it is clear that investments in hydrogen refueling stations will be profitable if the number of Fuel Cell vehicles increases. Conversely, the Fuel Cell vehicle market is hampered if there is no adequate infrastructure for hydrogen development. The opportunity to use Fuel Cells to store electrical energy is quite fascinating and bypasses some obstacles encountered with BEVs. The advantages are clear, since the charging times are reduced, compared to charging from an electric charging post, and the long-distance voyage is made easier, as the autonomy is much larger, i.e., the psycho-sociological anxiety is avoided. Therefore, the first part of the paper provides an overview of the current state of electric mobility in Portugal and the strategies adopted by the country. This is necessary to have a clear vision of how a new technology is accepted by the population and develops on the territory, that is the propensity of citizens to technological change. Subsequently, using current data on EV development and comparing information from recent years, this work aims to investigate the future prospects of FCEVs in Portugal by adopting a dynamic model called SERA (Scenario Evaluation and Regionalization Analysis), with which it is possible to identify the Portuguese districts and cities where an FC charging infrastructure is expected to be most beneficial. From the results obtained, the districts of Lisbon, Porto and Aveiro seem to be the most interested in adopting FC technology. This analysis aims to ensure a measured view of the credible development of this market segment.

“…Between years 2020-2030, the use of oil will be limited to cover the needs of the transport sector only as shown in Figure 2. Natural gas will play a protagonist role in all areas as a transitional fuel towards hydrogen economy [9,10]. Furthermore, part of the natural gas will be reformed in order to produce hydrogen, which is an environmentally friendly fuel, without any harmful emissions [11,12].…”

The present perspective aims to record the main actions that Cyprus, as a case study, needs to carry out in order to draw up a comprehensive long–term sustainable energy strategy for its transition from carbon economy to hydrogen economy. A brief description of the European sustainable energy strategy up to 2050 is provided. A transition to hydrogen economy by 2050, focusing on the importance of electricity interconnections including Cyprus’ crucial role with respect to the transition of Southeastern Mediterranean countries to hydrogen economy and how they could become energy exporters to Europe is discussed. Last but not least, this perspective presents the framework for drafting a long–term energy strategy for Cyprus and provides a set of targets for Cyprus’ energy transition to hydrogen economy by the year 2050
