Renewable Fuel Standard

In the United States, we have come to depend on plentiful and inexpensive energy to support our economy and lifestyles. In recent years, many questions have been raised regarding the sustainability of our current pattern of high consumption of nonrenewable energy and its environmental consequences. Further, because the United States imports about 55 percent of the nation's consumption of crude oil, there are additional concerns about the security of supply. Hence, efforts are being made to find alternatives to our current pathway, including greater energy efficiency and use of energy sources that could lower greenhouse gas (GHG) emissions such as nuclear and renewable sources, including solar, wind, geothermal, and biofuels. The United States has a long history with biofuels and the nation is on a course charted to achieve a substantial increase in biofuels. Renewable Fuel Standard evaluates the economic and environmental consequences of increasing biofuels production as a result of Renewable Fuels Standard, as amended by EISA (RFS2). The report describes biofuels produced in 2010 and those projected to be produced and consumed by 2022, reviews model projections and other estimates of the relative impact on the prices of land, and discusses the potential environmental harm and benefits of biofuels production and the barriers to achieving the RFS2 consumption mandate. Policy makers, investors, leaders in the transportation sector, and others with concerns for the environment, economy, and energy security can rely on the recommendations provided in this report.

Federal policy has played a key role in the emergence of the U.S. biofuels industry. Policy measures include minimum renewable fuel usage requirements, blending and production tax credits, an import tariff, loans, and research grants. This report focuses on the mandated minimum usage requirements, the RFS, whereby a minimum volume of biofuels is to be used in the national transport. fuel supply each year. It describes the general nature of the RFS mandate and its implementation, and outlines some emerging issues related to the sustainability of the continued growth in U.S. biofuels production needed to fulfill the expanding RFS mandate, as well as the emergence of potential unintended consequences of this rapid expansion.

The Renewable Fuel Standard (RFS) establishes minimum volumes of various types of renewable fuels that must be included in the U.S.'s supply of fuel for transportation. Those volumes -- as defined by the Energy Independence and Security Act of 2007 (EISA) -- are intended to grow each year through 2022. Recently, the requirements of the RFS have been met largely by blending gasoline with ethanol made from cornstarch. In the future, EISA requires the use of increasingly large amounts of "advanced biofuels," which include diesel made from biomass (such as soybean oil or animal fat), ethanol made from sugarcane, and cellulosic biofuels (made from converting the cellulose in plant materials into fuel). A main goal of the Renewable Fuel Standard is to reduce U.S. emissions of greenhouse gases, which contribute to climate change. Policymakers and analysts have raised concerns about the RFS, particularly about the feasibility of complying with the standard, whether it will increase prices for food and transportation fuels, and whether it will lead to the intended reductions in greenhouse gas emissions. This analysis evaluates how much the supply of various types of renewable fuels would have to increase over the next several years to comply with the RFS. It also examines how food prices, fuel prices, and emissions would vary in an illustrative year, 2017, under three scenarios for the Renewable Fuel Standard. Figures and tables.

Considering the ever-rising costs of traditional fuel paired with the increasing scarcity of its resources, it’s easy to see why exploring renewable fuels has become an increasingly critical goal for engineers, researchers, and end-users alike. However, due to the great diversity of technologies, policies, and attitudes, it can be difficult to gain a good well-rounded understanding of these types of fuels. Renewable Motor Fuels: The Past, the Present and the Uncertain Future presents an opportunity to gain an insightful understanding of all the key aspects of alternative automotive fuels in one book. Author Arthur Brownstein describes various sources of renewable motor fuels (including ethanol, algae, isobutanol, natural gas, and battery power) and their production processes, specific properties, and economic advantages/disadvantages. This comprehensive coverage of such an important topic is crucial for anyone with an interest in renewable fuels, from researchers to engineers to end-users. Presents a clear overview on a variety of renewable motor fuel technologies, balancing history, technology, and policy Provides the status of current and developing renewable motor fuel technologies and their uses worldwide Discusses the competitive economics of renewable fuel processes and their respective market interactions

A key topic of many technical discussions has been the development of alternative fuels to power the compression ignition engine. Reasons for this include the desire to reduce the dependency on petroleum-based fuel and, at the same time, to reduce the particulate matter (PM) and NOx emissions. Also, there has been interest generated in the diesel engine because of the reduction in greenhouse gases that has been proposed during the 2008-2012 time frame in Europe and the regulations that affect diesel engines in the United States.

The light-duty vehicle fleet is expected to undergo substantial technological changes over the next several decades. New powertrain designs, alternative fuels, advanced materials and significant changes to the vehicle body are being driven by increasingly stringent fuel economy and greenhouse gas emission standards. By the end of the next decade, cars and light-duty trucks will be more fuel efficient, weigh less, emit less air pollutants, have more safety features, and will be more expensive to purchase relative to current vehicles. Though the gasoline-powered spark ignition engine will continue to be the dominant powertrain configuration even through 2030, such vehicles will be equipped with advanced technologies, materials, electronics and controls, and aerodynamics. And by 2030, the deployment of alternative methods to propel and fuel vehicles and alternative modes of transportation, including autonomous vehicles, will be well underway. What are these new technologies - how will they work, and will some technologies be more effective than others? Written to inform The United States Department of Transportation's National Highway Traffic Safety Administration (NHTSA) and Environmental Protection Agency (EPA) Corporate Average Fuel Economy (CAFE) and greenhouse gas (GHG) emission standards, this new report from the National Research Council is a technical evaluation of costs, benefits, and implementation issues of fuel reduction technologies for next-generation light-duty vehicles. Cost, Effectiveness, and Deployment of Fuel Economy Technologies for Light-Duty Vehicles estimates the cost, potential efficiency improvements, and barriers to commercial deployment of technologies that might be employed from 2020 to 2030. This report describes these promising technologies and makes recommendations for their inclusion on the list of technologies applicable for the 2017-2025 CAFE standards.
