For a century, almost all light-duty vehicles (LDVs) have been powered by internal combustion engines operating on petroleum fuels. Energy security concerns about petroleum imports and the effect of greenhouse gas (GHG) emissions on global climate are driving interest in alternatives. Transitions to Alternative Vehicles and Fuels assesses the potential for reducing petroleum consumption and GHG emissions by 80 percent across the U.S. LDV fleet by 2050, relative to 2005. This report examines the current capability and estimated future performance and costs for each vehicle type and non-petroleum-based fuel technology as options that could significantly contribute to these goals. By analyzing scenarios that combine various fuel and vehicle pathways, the report also identifies barriers to implementation of these technologies and suggests policies to achieve the desired reductions. Several scenarios are promising, but strong, and effective policies such as research and development, subsidies, energy taxes, or regulations will be necessary to overcome barriers, such as cost and consumer choice.

Biojet fuels have the potential to make an important contribution towards decarbonising the aviation sector. Biojet Fuel in Aviation Applications: Production, Usage and Impact of Biofuels covers all aspects of this sustainable aviation fuel including aviation biofuel public policies, production technologies, physico-chemical properties, combustion performances, techno-economics of sustainable fuel production, sustainability and energywater-food (EWF) nexus. This must-have book also charts the current state of the industry by discussing the relevant industry players who are currently producing alternative aviation fuels and flight tests, while also providing a glimpse of the future of the industry. This comprehensive book is written for undergraduate students, postgraduate students, researchers, engineers and policy makers wanting to build up knowledge in the specific area of biojet fuel or the broader fields of sustainable energy and aeronautics. - Reviews major aviation and biojet fuel policies, legislations, initiatives and roadmaps around the world - Features existing and emerging biojet fuel production pathways from various feedstocks - Highlights the key properties of biojet fuels that ensures inter-operability with conventional jet aviation fuel - Discusses the economic aspects of the biojet fuel industry and the barriers preventing its commercialisation - Examines the sustainability of biojet fuel from a life cycle assessment, energy balance and EWF nexus point of views

"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.

Transport Revolutions: Moving People and Freight without Oil sets out the challenges to our growing dependence on transport fuelled by low-priced oil. These challenges include an early peak in world oil production and profound climate change resulting in part from oil use. It proposes responses to ensure effective, secure movement of people and goods in ways that make the best use of renewable sources of energy while minimizing environmental impacts. Transport Revolutions synthesizes engineering, economics, environment, organization, policy and technology, and draws extensively on current data to present important conclusions. The authors argue that land transport in the first half of the 21st century will feature at least two revolutions. One will involve the use of electric drives rather than internal combustion engines. Another will involve powering many of these drives directly from the electric grid - as trains and trolley buses are powered today - rather than from on-board fuel. They go on to discuss marine transport, whose future is less clear, and aviation, which could see the most dramatic breaks from current practice. With its expert analysis of the politics and business of transport, Transport Revolutions is essential reading for professionals and students in transport, energy, town planning and public policy.
