“…On the other hand, Rethink Energy's model establishes, however, that the cost of green H 2 will fall to slightly over $1/kg in 2035 as led by nations such as Brazil or Chile, generating the possibility of reaching even lower prices [70,71]. Consequently, achieving this price for green hydrogen reduces the level of emissions to zero, something that does not occur with blue hydrogen with 10% CO 2 emissions or the total release of gray hydrogen obtained only by steam methane reforming (SMR) or gasification [68].…”

Over the past few years, the rapid growth of air traffic and the associated increase in emissions have created a need for sustainable aviation. Motivated by these challenges, this paper explores how a 50-passenger regional aircraft can be hybridized to fly with the lowest possible emissions in 2040. In particular, the use of liquid hydrogen in this aircraft is an innovative power source that promises to reduce CO2 and NOx emissions to zero. Combined with a fuel-cell system, the energy obtained from the liquid hydrogen can be used efficiently. To realize a feasible concept in the near future considering the aspects of performance and security, the system must be hybridized. In terms of maximized aircraft sustainability, this paper analyses the flight phases and ground phases, resulting in an aircraft design with a significant reduction in operating costs. Promising technologies, such as a wingtip propeller and electric green taxiing, are discussed in this paper, and their potential impacts on the future of aviation are highlighted. In essence, the hybridization of regional aircraft is promising and feasible by 2040; however, more research is needed in the areas of fuel-cell technology, thermal management and hydrogen production and storage.

The research in energy storage and conversion is playing a critical role in energy policy as the innovation and technological progress are essential for achieving the energy transition and climate neutrality goals. Hydrogen Fuel Cell technology is considered a strategic element in the pursuit of sustainable and clean energy solutions. This technology is increasingly gaining attention in recent years as a potential substitute to conventional non‐renewable energy sources. Fuel cell technology can be employed for domestic/commercial use along with powering the transportation sector which currently employs the use of conventional battery systems. However, these systems pose severe limitations with respect to longer charging times and limited distance range. This review article aims at providing a comprehensive methodical overview of hydrogen‐based fuel cell technology along with key concepts, present day scenarios, including overview of the market and industry trends, government policies and initiatives, along with major stakeholders involved in scaling up the technology for mass consumption. The outlook of fuel cells, including their capability to revolutionise the energy sector is discussed. The technological advancements and breakthroughs on the horizon along with the challenges and safety concerns related to the widespread acceptance of fuel cells are analysed.

“…In this regard, the use of renewable resources will contribute to reducing polluting gases, decreasing the dependence of energy imports, and promoting local and regional economies [10][11][12]. Biodiesel -a non-toxic and biodegradable mixture of long chain fatty acid methyl esters made by transesterification of vegetable oils and animal fats -represents a prospective liquid transportation fuel with high potential to replace diesel and Jet-A fuel in the future with 60% less net-life cycle carbon dioxide emissions [13][14][15].…”
