Book Description
Hydrogen fuel is rapidly emerging as a clean energy carrier solution that has the potential to decarbonize a variety of industries, including, or predominantly, the transportation industry. Fuel cell electric vehicles (FCEVs), which electrochemically combine stored hydrogen with atmospheric oxygen to efficiently generate electricity while producing only water vapor and small amounts of heat, are heralded to be a game-changing technology. The so-called hydrogen economy has the potential to displace traditional fossil fuel-based economy, with the transportation industry being the first mover in the hydrogen space. Technological advances made in the last decade in the areas of hydrogen generation and fuel cell technology have enabled the current uptake of hydrogen-based solutions for vehicle applications. Reduced costs, climate change, and carbon tax mechanisms are driving many governments, manufacturers, and consumers toward hydrogen-powered vehicles. The major drawbacks of hydrogen compared to the other competing clean-energy technologies (e.g., battery power), is the high cost of hydrogen refueling and FCEVs. However, application of the economy of scale will enable further cost reduction and broad international uptake of hydrogen in automotive applications. This SAE EDGE™ Research Report explores the opportunities and challenges of hydrogen and fuel cell systems in the automotive industry. With the help of expert contributors, several different technological, economic, and safety aspects are considered to develop a better understanding of this emerging hydrogen-based automotive industry. While debates between proponents of battery electric vehicles (BEVs) and FCEVs continue, the current report discusses the unsettled issues in the latter technology and presents a critical overview of the hydrogen and fuel cell systems in the automotive industry. Finally, the report concludes with a series of recommendations aimed at the industry and government stakeholders for implementing and advancing hydrogen transportation projects. NOTE: SAE EDGE™ Research Reports are intended to identify and illuminate critical issues in emerging, but still unsettled, technologies of interest to the mobility industry. The goal of SAE EDGE™ Research Reports is to stimulate discussion and work in the hope of promoting and speeding resolution of identified issues. SAE EDGE™ Research Reports are not intended to resolve the issues they identify or close any topic to further scrutiny.

Book Description
HYDROGEN ELECTRICAL VEHICLES Hydrogen electrical vehicles are an essential component of the “Green New Deal” and this book covers cutting-edge technologies designed for fuel-cell-powered cars. The realization of the decision of 28 countries to keep global warming at 2 degrees and below, which is stated in the Paris Agreement, and the achievement of minimizing CO2 emissions, can only be accomplished by establishing a hydrogen ecosystem. A new geopolitical order is envisaged, in which sectors dealing with energy production, distribution, and storage, thus decreasing the carbon footprint, are reconstructed. In short, an economic order with new tax regulations is being created in which the carbon footprint will be followed. This global effort called the “Green Deal” is defined as a new growth strategy aiming at net-zero CO2 emissions. We know that the total share of transportation in CO2 emissions is about 24%. Therefore, efforts for reducing emissions must include utilizing hydrogen in transport. The subjects covered in the book include: An introduction to hydrogen and electrical vehicles; Hydrogen storage and compression systems; Hydrogen propulsion systems for UAVs; Test and evaluation of hydrogen fuel cell vehicles; Hydrogen production and PEM fuel cells for electrical vehicles; The power and durability issues of fuel cell vehicles. Audience The book will attract readers from diverse fields such as chemistry, physics, materials science, engineering, mechanical and chemical engineering, as well as energy-focused engineering and hydrogen generation industry programs that will take advantage of using this comprehensive review of the hydrogen electrical vehicles.

Book Description
Polymer Electrolyte Membrane (PEM) fuel cells convert chemical energy in hydrogen into electrical energy with water as the only by-product. Thus, PEM fuel cells hold great promise to reduce both pollutant emissions and dependency on fossil fuels, especially for transportation—passenger cars, utility vehicles, and buses—and small-scale stationary and portable power generators. But one of the greatest challenges to realizing the high efficiency and zero emissions potential of PEM fuel cells technology is heat and water management. This book provides an introduction to the essential concepts for effective thermal and water management in PEM fuel cells and an assessment on the current status of fundamental research in this field. The book offers you: • An overview of current energy and environmental challenges and their imperatives for the development of renewable energy resources, including discussion of the role of PEM fuel cells in addressing these issues; • Reviews of basic principles pertaining to PEM fuel cells, including thermodynamics, electrochemical reaction kinetics, flow, heat and mass transfer; and • Descriptions and discussions of water transport and management within a PEM fuel cell, including vapor- and liquid-phase water removal from the electrodes, the effects of two-phase flow, and solid water or ice dynamics and removal, particularly the specialized case of starting a PEM fuel cell at sub-freezing temperatures (cold start) and the various processes related to ice formation.

Book Description
Technologies and Approaches to Reducing the Fuel Consumption of Medium- and Heavy-Duty Vehicles evaluates various technologies and methods that could improve the fuel economy of medium- and heavy-duty vehicles, such as tractor-trailers, transit buses, and work trucks. The book also recommends approaches that federal agencies could use to regulate these vehicles' fuel consumption. Currently there are no fuel consumption standards for such vehicles, which account for about 26 percent of the transportation fuel used in the U.S. The miles-per-gallon measure used to regulate the fuel economy of passenger cars. is not appropriate for medium- and heavy-duty vehicles, which are designed above all to carry loads efficiently. Instead, any regulation of medium- and heavy-duty vehicles should use a metric that reflects the efficiency with which a vehicle moves goods or passengers, such as gallons per ton-mile, a unit that reflects the amount of fuel a vehicle would use to carry a ton of goods one mile. This is called load-specific fuel consumption (LSFC). The book estimates the improvements that various technologies could achieve over the next decade in seven vehicle types. For example, using advanced diesel engines in tractor-trailers could lower their fuel consumption by up to 20 percent by 2020, and improved aerodynamics could yield an 11 percent reduction. Hybrid powertrains could lower the fuel consumption of vehicles that stop frequently, such as garbage trucks and transit buses, by as much 35 percent in the same time frame.

Book Description
Hydrogen and fuel cells are vital technologies to ensure a secure and CO2-free energy future. Their development will take decades of extensive public and private effort to achieve technology breakthroughs and commercial maturity. Government research programs are indispensable for catalyzing the development process. This report maps the IEA countries' current efforts to research, develop and deploy the interlocking elements that constitute a "hydrogen economy", including CO2 capture and storage when hydrogen is produced out of fossil fuels. It provides an overview of what is being done, and by whom, covering an extensive complexity of national government R & D programs. The survey highlights the potential for exploiting the benefits of the international cooperation. This book draws primarily upon information contributed by IEA governments. In virtually all the IEA countries, important R & D and policy efforts on hydrogen and fuel cells are in place and expanding. Some are fully-integrated, government-funded programs, some are a key element in an overall strategy spread among multiple public and private efforts. The large amount of information provided in this publication reflects the vast array of technologies and logistics required to build the "hydrogen economy."--Publisher description.
