The widespread COVID-19 epidemic and political instability worldwide caused a significant transformation in the world’s fuel market. The invasion of Ukraine by Russia disrupted the flow of oil and gas among industrial nations that rely on them for manufacturing. The abrupt fall in petroleum supplies led to high gasoline costs at the pump. The continuing hostilities increased the demand for fuel as well as inflationary rates, both of which contributed to increases in the price of carbonised fuels. To successfully commercialize a suitable sustainable environmentally friendly replacement fuel, it is necessary to conduct research on the economic viability of alternative fuels. Hydrogen fuel appears to be a suitable alternative. It has zero-carbon emission, with water as the only byproduct. Researchers are exploring the development of new production methods that are sustainable and cost-efficient. Businesspeople are focusing on the logistics of moving, storing and promoting the use of this new fuel to usher in a new era in the fuel industry. In this Special Issue titled “The Future of Sustainable Aviation Fuels, Challenges and Solutions”, we provide views of the study of hydrogen fuel from different perspectives and include contributions from different research areas, enforcing the interdisciplinary interest in the application of hydrogen. “The Future of Sustainable Aviation Fuels, Challenges and Solutions” includes eight papers covering different technological aspects, from the effect of the addition of hydrogen to natural gas in diaphragm gas meters [1]. The other papers are titled as follows: Reactivity Model as a Tool to Compare the Combustion Process in Aviation Turbine Engines Powered by Synthetic Fuels [2]; Proton Exchange Membrane Hydrogen Fuel Cell as the Grid Connected Power Generator [3]; Assessment of Energy Storage from Photovoltaic Installations in Poland Using Batteries or Hydrogen [4]; Designing an AB2-Type Alloy (TiZr-CrMnMo) for the Hybrid Hydrogen Storage Concept [5]; The Role of Hydrogen in Achieving Long Term Japanese Energy System Goals [6]; Cost-Economic Analysis of Hydrogen for China’s Fuel Cell Transportation Field [7]; and Ammonia as Effective Hydrogen Storage: A Review on Production, Storage and Utilization.
