While the ultimate goal is transitioning to clean SAF, several factors necessitate the development of more efficient fuels before this transition can be fully realized in the aviation industry. Critical considerations, such as energy density and range, safety, compatibility with existing infrastructure, reliability, and performance, must be considered. For example, a high energy density (HED) is imperative in aviation fuels to enable long-range flights. Currently, conventional fossil fuels derived from petroleum, such as jet fuels, possess the necessary HED to facilitate long-distance travel without frequent refuelling. Compared to existing alternatives, polycycloalkanes offer a potential solution by providing HED, thus bridging the gap between conventional fuels and future sustainable options . The introduction of new fuels requires extensive testing, certification, and compatibility studies to ensure compliance with rigorous safety criteria and processes, which can be both time-consuming and costly. By focusing on more efficient fuels, such as polycycloalkanes, which exhibit properties similar to those of conventional fuels, the transition becomes smoother and less disruptive to existing safety protocols and infrastructure. Clean and sustainable energy sources, such as electric batteries or hydrogen fuel cells are promising, they generally exhibit lower energy densities compared to conventional fuels and may require modification to existing engines for compatibility .
