This textbook will be bought by graduate and senior undergraduate students studying renewable energy and the design and optimisation of hydrogen energy systems as well as the lecturers who teach these subjects. Hybrid Hydrogen Systems for Stationary and Transportation Applications will also be bought by researchers and practitioners working with hydrogen and fuel cells as well as policy makers and advocates of renewable energy.

With contributions from noted laboratory scientists, professors, and engineers, Hydrogen Energy and Vehicle Systems presents a new comprehensive approach for applying hydrogen-based technologies to the transportation and electric power generation sectors. It shows how these technologies can improve the efficiency and reliability of energy and trans

Climate change is becoming visible today, and so this book—through including innovative solutions and experimental research as well as state-of-the-art studies in challenging areas related to sustainable energy development based on hybrid energy systems that combine renewable energy systems with fuel cells—represents a useful resource for researchers in these fields. In this context, hydrogen fuel cell technology is one of the alternative solutions for the development of future clean energy systems. As this book presents the latest solutions, readers working in research areas related to the above are invited to read it.

Hydrogen fuel cell vehicles (HFCVs) could alleviate the nation's dependence on oil and reduce U.S. emissions of carbon dioxide, the major greenhouse gas. Industry-and government-sponsored research programs have made very impressive technical progress over the past several years, and several companies are currently introducing pre-commercial vehicles and hydrogen fueling stations in limited markets. However, to achieve wide hydrogen vehicle penetration, further technological advances are required for commercial viability, and vehicle manufacturer and hydrogen supplier activities must be coordinated. In particular, costs must be reduced, new automotive manufacturing technologies commercialized, and adequate supplies of hydrogen produced and made available to motorists. These efforts will require considerable resources, especially federal and private sector funding. This book estimates the resources that will be needed to bring HFCVs to the point of competitive self-sustainability in the marketplace. It also estimates the impact on oil consumption and carbon dioxide emissions as HFCVs become a large fraction of the light-duty vehicle fleet.

Hydrogen Fuel Cells for Road Vehicles addresses the main issues related to the application of hydrogen fuel cell technology in the road transportation sector. A preliminary treatment is given on fuel resources and atmospheric pollution concerns which are closely related to the current technology (internal combustion engine) used for moving people and goods. The authors deal, in particular, with the problems that can hinder a widespread hydrogen market (production, storage and distribution), as well as giving an analysis of fuel cell technologies available for utilization of this energy carrier in the automotive field. Hydrogen Fuel Cells for Road Vehicles also examines the concerns faced during the design and realization of a PEM fuel cell system with optimal size and efficiency, evidencing the impact of the individual auxiliary components on energy losses and dynamic stack performance. The book ends with the analysis of two practical case studies on fuel cell propulsion systems. Hydrogen Fuel Cells for Road Vehicles is a useful text for researchers, professionals and advanced students in the fields of automotive and environmental engineering.

Alternative propulsion technologies are becoming increasingly important with the rise of stricter regulations for vehicle efficiency, emission regulations, and concerns over the sustainability of crude oil supplies. The fuel cell is a critical component of alternative propulsion systems, and as such has many aspects to consider in its design. Fuel cell electric vehicles (FCEVs) powered by proton-exchange membrane fuel cells (PEFC) and fueled by hydrogen, offer the promise of zero emissions with excellent driving range of 300-400 miles, and fast refueling times; two major advantages over battery electric vehicles (BEVs). FCEVs face several remaining major challenges in order to achieve widespread and rapid commercialization. Many of the challenges, especially those from an FCEV system and subsystem cost and performance perspective are addressed in this book. Chapter topics include: • impact of FCEV commercialization • ways to address barriers to the market introduction of alternative vehicles • new hydrogen infrastructure cost comparisons • onboard chemical hydride storage • optimization of a fuel cell hybrid vehicle powertrain design

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.

The announcement of a hydrogen fuel initiative in the President's 2003 State of the Union speech substantially increased interest in the potential for hydrogen to play a major role in the nation's long-term energy future. Prior to that event, DOE asked the National Research Council to examine key technical issues about the hydrogen economy to assist in the development of its hydrogen R&D program. Included in the assessment were the current state of technology; future cost estimates; CO2 emissions; distribution, storage, and end use considerations; and the DOE RD&D program. The report provides an assessment of hydrogen as a fuel in the nation's future energy economy and describes a number of important challenges that must be overcome if it is to make a major energy contribution. Topics covered include the hydrogen end-use technologies, transportation, hydrogen production technologies, and transition issues for hydrogen in vehicles.
