The primary human activities that release carbon dioxide (CO2) into the atmosphere are the combustion of fossil fuels (coal, natural gas, and oil) to generate electricity, the provision of energy for transportation, and as a consequence of some industrial processes. Although aviation CO2 emissions only make up approximately 2.0 to 2.5 percent of total global annual CO2 emissions, research to reduce CO2 emissions is urgent because (1) such reductions may be legislated even as commercial air travel grows, (2) because it takes new technology a long time to propagate into and through the aviation fleet, and (3) because of the ongoing impact of global CO2 emissions. Commercial Aircraft Propulsion and Energy Systems Research develops a national research agenda for reducing CO2 emissions from commercial aviation. This report focuses on propulsion and energy technologies for reducing carbon emissions from large, commercial aircraftâ€" single-aisle and twin-aisle aircraft that carry 100 or more passengersâ€"because such aircraft account for more than 90 percent of global emissions from commercial aircraft. Moreover, while smaller aircraft also emit CO2, they make only a minor contribution to global emissions, and many technologies that reduce CO2 emissions for large aircraft also apply to smaller aircraft. As commercial aviation continues to grow in terms of revenue-passenger miles and cargo ton miles, CO2 emissions are expected to increase. To reduce the contribution of aviation to climate change, it is essential to improve the effectiveness of ongoing efforts to reduce emissions and initiate research into new approaches.

"TRB's Airport Cooperative Research Program (ACRP) Report 83: Assessing Opportunities for Alternative Fuel Distribution Programs consists of a guidebook and toolkit designed to help airports introduce and market alternative fuels to their airport community that includes tenants and consumers off airport. Alternative fuels considered include alternative jet fuel, green diesel, biodiesel, ethanol, compressed natural gas (CNG), liquefied petroleum gas (LPG), and electricity. The guidebook includes a step-by-step process to evaluate opportunities and constraints for alternative fuel distribution programs."--Publisher's description.

Aviation Fuels provides up-to-date data on fuel effects on combustion performance and use of alternative fuels in aircraft. This book covers the latest advances on aviation fuel technologies, including alternative fuels, feedstocks and manufacturing processes, combustion performance, chemical modeling, fuel systems compatibility and the technical and environmental challenges for implementing the use of alternative fuels for aviation.

Sustainable Alternatives for Aviation Fuels presents a technical and economic guide on the development of sustainable aviation fuels from renewable sources. With a focus on commercial viability and cost reduction, the book explores every aspect of the alternative aviation fuels supply chain, including commercially feasible and environmentally sound feedstock, production routes, the roles of catalysts in processing, conceptual process design, process economics, engine performance, future market trends and case studies. Readers are provided with the tools to make decisions at every stage that are supported by in-depth techno-economic analyses, lifecycle assessments, and considerations for development prospects within the context of sustainability. This book offers an excellent overview for readers involved in bioenergy and aviation. It is an invaluable resource for researchers and industry practitioners seeking to produce commercially viable, alternative aviation fuels. - Presents the current sustainable alternative fuels for aviation, including commercially viable and environmentally sound feedstock and production routes - Provides practical guidance on topics such as the role of catalysts in processing, conceptual process design and engine performance analysis - Explores process economics, market trends and LCA analysis, in addition to a techno-economic analysis of biojet fuel and its sustainability

ACRP Report 60: Guidelines for Integrating Alternative Jet Fuel into the Airport Setting is a handbook for airport operators and others associated with drop in alternative jet fuel production and delivery that summarizes issues and opportunities associated with locating (on or off airport) an alternative jet fuel production facility, and its fuel storage and distribution requirements. The handbook identifies the types and characteristics of alternative fuels; summarizes potential benefits; addresses legal, financial, environmental, and logistical considerations and opportunities; and aids in evaluating the feasibility of alternative jet fuel production facilities.

This analysis presents a “bottom up” projection of the potential production of alternative aviation (jet) fuels in North America (United States, Canada, and Mexico) and the European Union in the next decade. The analysis is based on available plans from individual companies and considers existing and emerging fuel production technologies. The analysis also forecasts how alternative fuels might contribute to greenhouse gas goals. Based on a review of fuel production companies' stated plans to produce jet fuel, the study incorporated company-specific data into seven scenarios varying alternative jet fuel production and expansion assumptions. This study supports the use of advanced alternative fuels as one important component of achieving emissions and environmental targets, although other additional measures and/or new technologies may also be required. The analysis suggests that the FAA goal of 1 billion gallons of alternative jet fuel use by U.S. aviation in 2018 is achievable.
