Hydrogen and fuel cell cars are being hyped today as few technologies have ever been. If by the per capita energy consumption of China and India were to approach that of South Korea, and if the Chinese and Indian populations increase at currently projected rates, those two supergiant countries by themselves would consume more oil than the entire world did in PW Picks: Books of the Week. Discover what to read next. Hydrogen could be generated from renewable electricity, but that would be even more expensive and, as discussed below, renewable electricity has better uses for the next few decades. In its conclusion, the book states that hydrogen will not be widely available as a transportation fuel for a long time, and describes other strategies, including energy conservation techniques, to combat global warming. The U. Yet any significant shift toward cars running on distributed hydrogen from natural gas or grid electrolysis would undermine efforts to fight global warming. What to do and how to do it? That will require some way of delivering massive quantities of hydrogen to tens of thousands of local fueling stations. In a plug-in hybrid, the process of electricity transmission, charging an onboard battery and discharging the battery would leave 75 to 80 percent of the original electricity to drive the motor. When I helped oversee the hydrogen and fuel cell and alternative vehicle programs at the Energy Departments Office of Energy Efficiency and Renewable Energy in the s, I was a big supporter of hydrogen and transportation fuel cell vehicle FCV programs, helping to boost the funding for those programs substantially. Finally, natural gas has too much economic and environmental value to the electric utility, industrial, and building sectors to justify diverting significant quantities to the transportation sector, thereby increasing the price for all users. Burning a gallon of gasoline releases about 20 pounds of CO 2. Natural gas is no bridge to a better future. This debate will not be resolved here, but it does appear credible that oil production will peak in the first half of this century and will possibly decline at a relatively rapid rate thereafter, even as demand increases. This does not sound clean or "pollution-free". Worry about oil supplies is one of the factors behind Shell's growing research into hydrogen see Chapter 7. Hydrogen, first and foremost, is not a primary fuel, like natural gas or coal or wood, which we can drill or dig for or chop down and then use at once. Hydrogen burns nearly invisibly, and people have unwittingly stepped into hydrogen flames. Even with technology advances, a metric-ton truck might deliver only about kg of hydrogen into onsite high-pressure storage. Canada has a significant program because of the leadership of Ballard Power Systems Inc. The Hype About Hydrogen : Fact and Fiction in the Race to Save the Climate Writer Most oil is used in transportation. The real deal on the future of the hydrogen economy Having read Jeremy Rifkin's interesting, but rose-colored and somewhat tangential take on the future of the hydrogen fuel cell: The Hydrogen Economy: The Creation of the World-Wide Energy Web and the Redistribution of Power on Earth , I was pleased to read something from a full-time energy professional. From hybrid cars to fuel cells: Is technology moving us closer to a hydrogen fix? Add links. Mar 07, Mark rated it liked it Shelves: nonfiction. Between and , the International Energy Agency projects that coal generation will double. Only a limited number of fuels are plausible alternatives for gasoline, and one enormous benefit of hydrogen over others is that it can be generated by a variety of different sources, thus potentially minimizing dependence on any one. In addition, any high-pressure storage tank presents a risk of rupture. The high-risk and long-payback nature of this investment would seem far too great for most investors, especially given the history of alternative fuel vehicles. But first: a brief history of the California Hydrogen Highway Network. Most of a CH 4 -based investment would also likely be stranded once the ultimate transition to a pure hydrogen economy was made, because that would almost certainly rely on centralized production and not make use of small CH 4 reformers. The difficulties involved in the transition to hydrogen will likely be as much organizational and institutional as technical. Right now, not only is electricity ubiquitous i. Centralized production of hydrogen is the ultimate goal. Who will spend the hundreds of billions of dollars on a wholly new nationwide infrastructure to provide ready access to hydrogen for consumers with fuel cell vehicles until millions of hydrogen vehicles are on the road? Fuel cells are one of the Holy Grails of energy technology see Chapter 2. Plug-ins would be better at utilizing zero-carbon electricity because the overall hydrogen fueling process is inherently costly and inefficient. Hydrogen, however, will escape quickly into the atmosphere as a very diffuse gas. More Books by Joseph J. Thus, beyond limited pilot stations, it would be unwise to build thousands of local refueling stations based on steam CH 4 reforming or, for that matter, based on any technology not easily adaptable to delivery of greenhouse gas-free hydrogen. It then reviews the issue of the greenhouse effect and offers four reasons why hydrogen would not be useful in reducing greenhouse gas emissions:. So why buy one? Thus, delaying action until we are past the peak may put us at significant risk. His central chapter lays out the case for global warming and the potential for catastrophic climate change in the next few decades. CO2 emissions forecast for Showing Leonardo Maia rated it liked it Nov 24, Building these coal plants would dramatically increase the chances of catastrophic climate change. As Romm Cool Companies , a former Department of Energy official in the Clinton administration, points out, however, hydrogen is an energy carrier, not an energy source at least until we tame nuclear fusion. The history of hydrogen and its methods of production are then described. Ongoing efforts are exploring higher pressure storage at up to 10, psi, liquid hydrogen storage, and other solid and liquid forms of storage such as metal hydrides, organic hydrides, and carbon fibers among other options. But on Earth, it is bound up tightly in molecules of water, coal, natural gas, and so on. The United States has a great deal of relevant experience in the area of alternative fuel vehicles that is often ignored in discussions about hydrogen. The plan touches on this, but almost certainly underestimates its importance in supporting the large market changes that will clearly be required. Since only "a limited number of fuels are plausible alternatives for gasoline" p. So, what's that mean? William Clay Ford Jr. However, many automotive and energy companies and leading transportation energy analysts are leaning towards fuel cell or combustion engine vehicles running on hydrogen as the best options for the next dominant design in automobiles. Joseph Romm. For these reasons, hydrogen is subject to strict and cumbersome codes and standards, especially when used in an enclosed space where a leak might create a growing gas bubble. Typical commercial electrolysis units require about 50 kilowatt- hours per kg, an energy efficiency of 70 percent. To unbind it, a great deal of energy must be used. Lists with This Book. Straight Up. I miss the electric car. However, such a dramatic step forward in vehicle technology and energy infrastructure presents huge challenges. Mark A. A good read! Using nuclear power to make hydrogen is "a long stretch," he says. The Hype About Hydrogen : Fact and Fiction in the Race to Save the Climate Reviews Over 1 million new vehicles are purchased each year in California. Since oil is a finite, nonrenewable resource, analysts have attempted to predict when production will peak and start declining. Original Title. Romm See All. Funding for hybrid vehicles, including fuel cells, was significantly increased. It is generated through the conversion of another fuel source, such as natural gas, usually by electrolysis, and can be stored for later use and reconverted into power. This is a big advantage. It then reviews the issue of the greenhouse effect and offers four reasons why hydrogen would not be useful in reducing greenhouse gas emissions:. A tedious jeremiad. These efforts may be important to both environmental and economic vitality in the state. Others might not be so fascinated. Only a limited number of fuels are plausible alternatives for gasoline, and one enormous benefit of hydrogen over others is that it can be generated by a variety of different sources, thus potentially minimizing dependence on any one. Any effective hydrogen economy would require an infrastructure that could use zero-carbon power to electrolyze water into hydrogen, convey this highly diffuse gas long distances, and pump it at high pressure into the car -— all for the purpose of converting the hydrogen back to electricity in a fuel cell to drive electric motor.

  • What Do You Know About Alternative Energy? Development and Use of a Diagnostic Instrument for Upper Secondary School Science
    What do you know about alternative energy? Development and use of a diagnostic instrument for upper secondary school science Abstract The need for renewable and non-fossil fuels is now recognised by nations throughout the world. Consequently, an understanding of alternative energy is needed both in schools and in everyday life-long learning situations. This study developed a two-tier instrument to diagnose students’ understanding and alternative conceptions about alternative energy in terms of: sources of alternative energy, greenhouse gas emission, as well as advantages, and disadvantages. Results obtained with Year 10 and 11 students (n = 491) using the 12-item two-tier instrument (α = 0.61) showed that students’ understanding of alternative energy was low (M = 7.03; SD = 3.90). The 23 alternative conceptions about alternative energy sources that could be identified from the instrument are reported. The implications for teaching and learning about alternative energy and suggestions for further development and improvement of the instrument are presented. Keywords: Alternative energy; Environmental education; Alternative conceptions; Two-tier test items; Diagnostic assessment Introduction The world’s population is rapidly increasing causing a rise in the demand for energy use. Conventionally, the sources of energy used worldwide are coal, oil, and other fossil fuels such as natural gas. However, concerns about the depletion of these fossil fuels, particularly of oil, and their impact on the environment and sustainability is so huge that groups of countries have developed environmental protection policies, such as the Kyoto Protocol, to curb the contribution to global warming through Clean Development Mechanisms (CDM), carbon emission trading, and joint implementation (UNFCCC, 2011a).

  • The Bumpy Road to Hydrogen
    Year 2006 UCD—ITS—RP—06—16 The Bumpy Road to Hydrogen Daniel Sperling Joan Ogden Institute of Transportation Studies ◊ University of California, Davis One Shields Avenue ◊ Davis, California 95616 PHONE: (530) 752-6548 ◊ FAX: (530) 752-6572 WEB: http://its.ucdavis.edu/ The Bumpy Road to Hydrogen1 Daniel Sperling and Joan Ogden Institute of Transportation Studies University of California, Davis Davis, CA 95616 The history of alternative transportation fuels is largely a history of failures. Niche fuels such as liquefied petroleum gases (LPG) and compressed natural gas (CNG) have persisted here and there over the years, but never captured significant market penetration for a sustained period. The two exceptions are ethanol in Brazil, made from sugar cane, and ethanol in the US, made from corn. For both these cases, the fuel was heavily subsidized and protected for decades. They are now commercially successful, though at relatively small volumes, and will remain so as long as oil prices remain high. The real lesson is that success came only after decades of durable policy and subsidies, high oil prices and, in the case of Brazil, a committed automotive industry (first building dedicated ethanol vehicles and then after their failure following a decade later with flexible fuel vehicles). Will hydrogen succeed, where so many previous alternatives have failed? Will hydrogen be able to elicit durable policy support, as did ethanol in Brazil and the US? Might hydrogen succeed on a grand scale, where others have not? Hydrogen clearly provides the potential for huge energy and environmental improvements. But skeptics abound, for many good reasons.

California Governor Arnold Schwarzenegger explicitly recognized that urgency by committing the state in 2005 to reduce greenhouse gas ("GHG") emissions to eighty percent below 1990 levels by 2050,1 a difficult target that would require a radical change in California's energy system, particularly transportation. Governor Schwarzenegger's greenhouse target is, however, directly at odds with another of the governor's plans, the hydrogen highway. Hydrogen cars are an exceedingly costly greenhouse gas strategy and an inefficient way to utilize renewable or zero-carbon primary energy resources, which will be critical to achieving California's ambitious greenhouse gas target.

  • An Environmental Analysis of FCEV and H2-ICE Vehicles Using the Ecoscore Methodology
    Page 0635 World Electric Vehicle Journal Vol. 3 - ISSN 2032-6653 - © 2009 AVERE EVS24 Stavanger, Norway, May 13-16, 2009 An environmental analysis of FCEV and H2-ICE vehicles using the Ecoscore methodology Sergeant N. 1, Boureima F.-S., Matheys J., Timmermans J.-M. & Van Mierlo J. 1Vrije Universiteit Brussel, Department ETEC, Building Z, Pleinlaan 2, 1050 Brussels, Belgium, [email protected] Abstract The environmental issues caused by fossil fuels for transportation are numerous: greenhouse gas emissions are enhancing global warming, city smog, ozone and noise are causing major health problems, acid rain impacts our ecosystems, etc. Strong research efforts have therefore been performed towards alternative fuels and drive trains and hydrogen is still one of the most promising but at the same time controversial possibilities. The environmental impact of hydrogen used in a fuel cell (FCEV) or internal combustion engine vehicle (ICEV) - depends strongly on the production pathway for hydrogen and should therefore be evaluated on a well-to-wheel basis. In this paper, the Ecoscore methodology is used to assess the environmental impact of H2-ICE and fuel cell vehicles on a well-to-wheel basis. The Ecoscore is an environmental indicator for vehicles taking into account the impact on global warming, air quality depletion (divided into impact on human health and ecosystems) and noise. The Ecoscores of two FCEV and one H2-ICEV are calculated for different hydrogen production pathways (electrolysis and Steam Methane Reforming (SMR)), as well as for different methods of hydrogen storage (compression and liquefaction) and distribution (pipeline and truck). The highest Ecoscores and thus best results - are obtained for vehicles using hydrogen from electrolysis produced with 100 % renewable energy, followed by SMR and then electrolysis using the Belgian electricity mix.

  • 'Hydrogen: Too Dangerous to Base Our Future Upon?'
    SYMPOSIUM SERIES NO. 151 # 2006 Crown Copyright ‘HYDROGEN: TOO DANGEROUS TO BASE OUR FUTURE UPON?’ M Ricci, G Newsholme, P Bellaby, R Flynn1 # Crown Copyright 2006. This article is published with the permission of the Controller of HMSO and the Queen’s Printer for Scotland Growing concerns about global warming, air pollution, the depletion of fossil fuels and geopolitical fears regarding their future availability are driving massive investment in the search to meet the future energy needs of the world economy in a sustainable and environmentally friendly way. Hydrogen based technologies have been identified by many countries, multi-national companies and institutions as a major “energy carrier” in their multi-strand future energy scenarios. Hydrogen, however, is a danger- ous substance2 and some commentators express the view that this highly flammable gas is too hazardous to form a significant element of our future energy policy. In common with other technological systems, those based on hydrogen will inevi- tably involve risks associated with possible hazardous situations posing threats to safety, public health or the environment. This paper objectively reviews the key hazar- dous properties of hydrogen and compares them with those of current fuels in common usage by drawing on an extensive review of relevant literatures. It then illustrates the way in which prospective risks associated with hydrogen are currently assessed and represented by various experts and communicated to the wider public. The picture emerging from this review is an inconsistent one, where uncertainties and knowledge gaps abound, despite an overall “unspoken consensus” on hydrogen. The paper proceeds to explore how the issue of risk perception, as conceptualised within the sociology of risk, relates to the development of hydrogen as the fuel of the future.
