Pathways to a Hydrogen Future


Book Description

Hydrogen may someday fuel our cars and power and heat our homes and businesses and revolutionize the way we use energy. Moving to a hydrogen economy could help reduce our reliance on foreign oil, improve local air quality, and reduce the risk of climate change. Despite the potential of hydrogen, there is no guarantee that the hydrogen economy will happen as the obstacles are considerable and the competing visions are many. Pathways to a Hydrogen Future seeks to untangle the competing visions of a hydrogen economy, explain the trade-offs and obstacles and offer recommendations for a path forward. The results are based on a detailed simulation model developed at Sandia National Laboratories: "The Hydrogen Futures Simulation Model (H2Sim)". The H2Sim is a high-level strategic tool for evaluating the economic and environmental trade-offs of alternative hydrogen production, storage, transport, and end use options in the year 2020. An executive version of H2Sim is included with the book allowing readers to explore the various scenarios discussed. H2Sim's ease of use and its ability to provide answers to these types of questions make it a powerful educational and policy making tool. The model's structure is ideal for exploring "what-if" questions, such as: Can fuel cell vehicles (FCVs) compete economically with current cars if the FCVs are 2.5 times as efficient? Should the hydrogen be produced at fueling stations or at central locations and transported to fueling stations?* Includes an executive version of H2Sim allowing readers to explore the various scenarios discussed * H2Sim's ease of use and ability to provide answers makes it a powerful educational and policy making tool * The model's structure is ideal for exploring "what-if" questions, such as: Can fuel cell vehicles (FCVs) compete economically with current cars if the FCVs are 2.5 times as efficient?

It provides broad coverage of the most important fields of modern hydrogen technology: hydrogen properties, production, storage, conversion to power, and applications in materials science. In so doing, the book covers all the pertinent materials classes: metal hydrides, inorganic porous solids, organic materials, and nanotubes. The authors present the entire view from fundamental research to viable devices and systems, including the latest scientific results and discoveries, practical approaches to design and engineering, as well as functioning prototypes and advanced systems.




The Hydrogen Economy


Book Description

This book highlights the opportunities and the challenges of introducing hydrogen as alternative transport fuel from an economic, technical and environmental point of view. Through its multi-disciplinary approach the book provides researchers, decision makers and policy makers with a solid and wide-ranging knowledge base concerning the hydrogen economy.




Solar Hydrogen


Book Description

With reference to many examples as well as to new technologies, written by experts in the field, this accessible book provides insight into a crucial technology and numerous color pictures contribute to the book's readability.




The Hydrogen Economy


Book Description

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.




Liquid Hydrogen


Book Description

to the German Edition This book is based on published material, oral presentations and lecture courses, as well as the author's personal research in the specific field of space technology and in the general areas of energy storage and transfer, and cryogenics. The science and technology of liquid hydrogen-once essential prere quisites for the rapid development of space technology-are now also proving to be more and more important for the energy production of the future. Hydrogen as an energy carrier can generally mediate the existing disparity between nuclear energy and regenerative energy, both of which are indispensable for the future. Hydrogen, as a secondary energy carrier, can be produced from these primary energy sources with minimal environmental impact and without the detrimental, long-term pollution effects of current fossil fuel technology. Hydrogen, therefore, represents the ultimate in energy technology. The initial, large-scale application of hydrogen as a secondary energy was as a high-energy rocket propellant. The procedures for its large scale liquefaction, storage and employment were generally developed in the U.S. Currently in Europe similar activities are being conducted only in France. The effort in West Germany involves testing hydrogen-oxygen and hydrogen-fluorine rocket engines, studying also the physical and technical characteristics of slush hydrogen-mixture of the solid and liquid phase-and is concentrating currently on R&D applications of liquid hydrogen as an alternate fuel. Similar activities are also being conducted in Japan and Canada.




The Hydrogen Revolution


Book Description

Named a Financial Times Best Book of 2021 An energy expert shows why hydrogen can fight climate change and become the fuel of the future We’re constantly told that our planet is in crisis; that to save it, we must stop traveling, stop eating meat, even stop having children. But in The Hydrogen Revolution, Marco Alverà argues that we don’t need to upend our lives. We just need a new kind of fuel: hydrogen. From transportation and infrastructure to heating and electricity, hydrogen could eliminate fossil fuels, boost economic growth, and encourage global action on climate change. It could also solve the most bedeviling aspects of today’s renewable energy—from transporting and storing wind and solar energy and their vulnerability to weather changes to the inefficiency and limited utility of heavy, short-lasting batteries. The Hydrogen Revolution isn’t just a manifesto for a powerful new technology. It’s a hopeful reminder that despite the gloomy headlines about the fate of our planet, there’s still an opportunity to turn things around.




Gaseous Hydrogen Embrittlement of Materials in Energy Technologies

The Hype About Hydrogen


Book Description

Lately it has become a matter of conventional wisdom that hydrogen will solve many of our energy and environmental problems. Nearly everyone -- environmentalists, mainstream media commentators, industry analysts, General Motors, and even President Bush -- seems to expect emission-free hydrogen fuel cells to ride to the rescue in a matter of years, or at most a decade or two. Not so fast, says Joseph Romm. In The Hype about Hydrogen, he explains why hydrogen isn't the quick technological fix it's cracked up to be, and why cheering for fuel cells to sweep the market is not a viable strategy for combating climate change. Buildings and factories powered by fuel cells may indeed become common after 2010, Joseph Romm argues, but when it comes to transportation, the biggest source of greenhouse-gas emissions, hydrogen is unlikely to have a significant impact before 2050. The Hype about Hydrogen offers a hype-free explanation of hydrogen and fuel cell technologies, takes a hard look at the practical difficulties of transitioning to a hydrogen economy, and reveals why, given increasingly strong evidence of the gravity of climate change, neither government policy nor business investment should be based on the belief that hydrogen cars will have meaningful commercial success in the near or medium term. Romm, who helped run the federal government's program on hydrogen and fuel cells during the Clinton administration, provides a provocative primer on the politics, business, and technology of hydrogen and climate protection.
