“…Turbojet and turbofan engines are the most common engines used in commercial aviation, with turbofans being more prevalent due to their greater efficiency and reduced noise output. These engines work by drawing air into the engine, compressing it, mixing it with fuel, and igniting the mixture to produce thrust [25,26]. The compatibility of biofuels with jet engines has been extensively tested, demonstrating that biofuels can replace conventional jet fuel up to a 50% blend with minimal to no modifications required to the engines [22].…”

“…Studies continue to focus on the long-term impacts of biofuel use on engine wear and tear, maintenance schedules, and overall lifecycle costs [19,26]. Additionally, the research emphasizes the need for industry-wide standards and certification processes to ensure that biofuels not only meet the technical requirements of various engines but also contribute positively to environmental sustainability goals without compromising safety or performance [14,15].…”

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.

Renewable hydrogen and e-fuels, synthesized from captured CO 2 and renewable H 2 , are feasible ways to achieve transport decarbonization, particularly in medium/heavy-duty applications and the maritime sector, where compression ignition engines predominate. Hydrogen and methanol are low carbonintensive fuels, which can be used in these engines by carrying out dual-fuel combustion with a diesel-like fuel. Under low load engine conditions, reaching very high substitutions of the fossil diesel fuel can be a major challenge as the presence of these fuels affects negatively the autoignition process. Therefore, this work explores the substitution limits in dual-fuel mode with hydrogen and methanol under low load conditions (5.2 bar IMEP) for two different compression ratios (15.84:1 and 18.04:1) using a 1.13 L single-cylinder engine. Increasing the compression ratio allowed improvement of the maximum diesel substitution from 55 to 82% (also achieving a significant improvement of the thermal efficiency) with methanol and from 91 to 93% with H 2 (but decreasing the thermal efficiency due to higher heat transfer losses).
