“…Recent studies have been devoted to proposing reliable frameworks for performing LCA in the aviation sector . As a showcase, we mention a novel LCA study on commercial aviation (passengers and cargo) capable of ensuring transparency and comparability when evaluating the overall environmental performances of four emerging aviation systems, i.e., biofuel, e-fuel, electric, and hydrogen . This study provides a guideline for LCA practitioners addressing new energy sources for future aviation.…”

CO 2 can be converted into value-added products such as fuels, chemicals, and building materials, adding an economic incentive for CO 2 capture and green economy, while also reducing the environmental footprint of hard-to-abate industries such as aviation, construction, and metallurgy. Nonetheless, most available technologies for direct CO 2 conversion, while promising, are still in early development stages, facing technical and economic challenges for their scale-up, questioning their viability to truly instill a timely impact on global CO 2 emissions. Furthermore, a clear environmental benefit should be obtained for the new processes versus the traditional ones they are replacing in the market. In this perspective, we examine the range of available technologies for direct CO 2 conversion using thermal, electrical, and photochemical routes and mineralization including the advancements in their role in synthesizing a range of resulting products from methanol, methane, carbon monoxide, and solid carbonates. We offer insights on the trends in current research and development and the required direction to expedite the technological readiness of attractive CO 2 conversion technologies in terms of catalytic material and reactor design. We also highlight the important role of modeling (molecular and process levels) as an enabling tool to deploy these technologies at the commercial scale originating from understanding their behavior at the molecular level. Lastly, we highlight the significance of carrying out reliable life cycle analysis in identifying the environmental hotspots as well as gaps in the technology that allows improving their environmental footprint and economic attractiveness.

“…They operate similarly to automobile engines, using the expansion of burning gas to drive pistons. These engines are typically powered by avgas (aviation gasoline), which is a high-octane fuel suitable for the high compression ratios of aviation engines [17,18]. The transition to biofuels in piston engines poses challenges primarily due to the biofuels' different chemical characteristics compared to avgas, such as lower energy content per volume and variations in stoichiometric fuel-to-air ratio, which can affect engine performance and maintenance [19,20].…”

This comprehensive review examines the role of sustainable aviation fuels (SAFs) in promoting a more environmentally responsible aviation industry. This study explores various types of biofuels, including hydroprocessed esters and fatty acids (HEFAs), Fischer–Tropsch (FT) fuels, alcohol-to-jet (ATJ) fuels, and oil derived from algae. Technological advancements in production and processing have enabled SAF to offer significant reductions in greenhouse gas emissions and other pollutants, contributing to a cleaner environment and better air quality. The review addresses the environmental, economic, and technical benefits of SAF, as well as the challenges associated with their adoption. Lifecycle analyses are used to assess the net environmental benefits of SAF, with a focus on feedstock sustainability, energy efficiency, and potential impacts on biodiversity and land use. Challenges such as economic viability, scalability, and regulatory compliance are discussed, with emphasis on the need for supportive policies and international collaboration to ensure the long-term sustainability of SAF. This study also explores current applications of SAF in commercial airlines and military settings, highlighting successful case studies and regional differences driven by policy frameworks and government incentives. By promoting technological innovation and addressing regulatory and economic barriers, SAF has the potential to play a crucial role in the aviation industry’s transition toward sustainability.
