Future studies should aim to bridge the current methodological gaps by focusing specifically on several critical areas. Firstly, efforts should be directed towards significant cost reduction in the production and deployment of sustainable aviation fuels. This includes exploring innovative technologies and optimizing existing processes to make SAF production more economically viable. Secondly, enhancing process efficiency is crucial, which involves refining the conversion processes, improving yield rates, and minimizing energy consumption throughout the production cycle. Lastly, seamless integration of renewable energy resources into SAF production must be prioritized. This entails developing hybrid systems that combine various renewable energy sources, such as solar, wind, and biomass, to create a more sustainable and resilient fuel supply chain.
