The aviation industry’s commitment to reducing GHG emissions along with increasing oil prices have sparked the need for renewable and affordable energy sources tailored to this sector’s very specific needs. As jet engines cannot be readily "electrified", turning to biofuels is the most viable option. However this is a kind of transportation for which traditional biofuels, such as bioethanol and biodiesel, do not fulfill key fuel requirements. Therefore, different solutions to this situation are being researched and tested around the globe, which makes navigating this scenario particularly challenging. Hence this book guides its readers through this intricate subject, bringing them up to speed with its current status and future prospects both from the academic and the industry point of view. The authors discuss the issues that surround research and use of biojet fuels, such as policy, markets, certification and performance requirements, life cycle assessment, and the economic and technical barriers to their full implementation. At the same time, science and technology chapters delve into the technical aspects of the currently tested and the most promising technology in development, as well as their respective feedstocks and the use of additives as a way of adapting them to meet certain specifications. Conversion processes such as hydrotreatment, synthetic biology, pyrolysis, hydrothermal liquefaction and Fisher-Tropsch are explored and their results are assessed for current and future viability. Hence, readers involved in bioenergy and aviation sectors, be it in research, planning or policy making activities, can benefit of this thorough overview.
Presents the current status of biofuels for the aviation sector, including technologies that are currently in use and the most promising future technologies, their production processes and viability.Explains the requirements for certification and performance of aviation fuels and how that can be achieved by biofuels. Explores the economic and policy issues, as well as life cycle assessment, a comparative technoeconomic analysis of promising technologies and a roadmap to the future.
