Pathways for a transition to a sustainable hydrogen transportation fuel infrastructure in California


Book Description

Inhaltsangabe:Abstract: As society enters the 21st century, there is a growing awareness of the burdens being placed on the planet, as its ability to keep up with the demands of modern society are strained. One of the major contributors to this burden happens to be a main resource required for sustained development. Energy has always been, and will always be a necessary resource for existence. Since the industrial revolution, fossil fuels such as coal and oil have been the main-stay fuel to accommodate society's appetite. As the demand for this resource increases, the climatic and socio-economic costs of this fuel become more acute, and it is well documented that the supply of this fuel is not endless. One of the major consumers of this fuel, as a society, is the transportation sector. The processes in place which take it from the ground, to its combustion as a fuel, are some of the main culprits which adversely affect the planet. This thesis explores the issues associated with the introduction of another energy resource Hydrogen as a replacement fuel for the transportation industry. It is argued that for the transportation sector, Hydrogen offers the most promising alternative as a fuel. Making Hydrogen readily available and affordable through the retail infrastructure is of paramount importance, if its widespread use is to be achieved. The logistics of this are explored, and it is believed that the introduction of small Hydrogen fuelers at existing retail outlets, is the preferred method to instantiate the transition in the short to medium term. Those fueling stations can utilize grid electricity to produce Hydrogen by the means of water electrolysis, or take advantage of the existing Natural Gas distribution infrastructure to produce Hydrogen via steam reformation. This thesis examines the Well-to-Wheels impacts and economic feasibility of those options and compares them to existing vehicle and fuel technologies. The state of California was chosen as a target market due to its high automobile density, the resulting pollution issues, and its clear mandate on promoting alternative energy sources.

Sustainable Transportation Energy Pathways


Book Description

Sustainable Transportation Energy Pathways: A Research Summary for Decision Makers (334 pages, black & white figures) We stand at the beginning of a revolution in transportation and energy. Over the next several decades, a convergence of growing demand, resource constraints, and environmental imperatives will reshape our energy system. These forces will change the way we travel and the kinds of vehicles we drive, and will challenge the century-long primacy of petroleum and the internal combustion engine. This transformation will unfold over many decades. But it poses urgent questions today because of the long time horizon inherent in developing new technologies and changing the energy system. This book is written to help inform decision makers in industry and government about the potential costs and benefits of different fuel/vehicle pathways, and illuminates viable transition strategies toward a sustainable transportation future. It focuses on characterizing and comparing four fuel pathways: hydrogen, biofuels, electricity, and fossil fuels. Technical aspects, cost, market issues, environmental implications, and transition issues for each individual pathway are explored, creating a strong basis for the development of integrative scenarios to address policy goals such as reducing greenhouse gas emissions or oil dependency. Case studies are presented that inform carbon and alternative fuel policies in California, the United States, and beyond. The book addresses four "big picture" questions in a series of 13 chapters written by researchers at the Institute of Transportation Studies, University of California, Davis: What do individual fuel/vehicle pathways look like for biofuels, electricity and hydrogen? How do these pathways compare? How could we combine pathways and approaches to meet societal goals for carbon reduction, energy security, etc.? What policy measures and tools are needed to encourage progress toward sustainable transportation? The authors find that there is no single "fuel or vehicle of the future," expecting instead to see a diverse mix of fuels and vehicle types that could vary by region and application. A portfolio approach incorporating efficiency, alternative fuels and travel demand reductions will produce the best chance of meeting societal goals. The book draws heavily on insights gained from the Sustainable Transportation Energy Pathways (STEPS) research program at the University of California, Davis. STEPS began in 2007, with a goal of performing robust, impartial comparative analyses of different fuel/vehicle pathways drawing on engineering, economics, environmental science, and consumer behavior. An interdisciplinary team of 15 Ph.D.-level researchers and 25 graduate students was formed, with support coming from 23 diverse sponsoring organizations, each of which contributes to the STEPS consortium.




Renewable Hydrogen Technologies


Book Description

The fields covered by the hydrogen energy topic have grown rapidly, and now it has become clearly multidisciplinary. In addition to production, hydrogen purification and especially storage are key challenges that could limit the use of hydrogen fuel. In this book, the purification of hydrogen with membrane technology and its storage in "solid" form using new hydrides and carbon materials are addressed. Other novelties of this volume include the power conditioning of water electrolyzers, the integration in the electric grid of renewable hydrogen systems and the future role of microreactors and micro-process engineering in hydrogen technology as well as the potential of computational fluid dynamics to hydrogen equipment design and the assessment of safety issues.

Renewable Transportation Fuel for California's Electric-drive Vehicles


Book Description

California has enacted a number of policies that incentivize the use of advanced vehicle technologies and fuels to help reduce petroleum usage, air pollution and greenhouse gas emissions. These include the Pavley greenhouse gas emissions standards, the Low Carbon Fuel Standard (LCFS), the Zero Emission Vehicle (ZEV) and Low-Emission Vehicle (LEV) regulations and initiatives that support adoption of alternative fuels, such as the Air Quality Improvement Program (AQIP) and Alternative Fuel Incentive Program (AFIP). In addition, the state has set an economy-wide goal of reducing greenhouse gas (GHG) emissions 80% below 1990 levels by 2050. Greatly reducing GHG emissions from the transportation sector will likely require large-scale adoption of electric-drive - plug-in hybrid electric, battery-electric, or hydrogen fuel cell vehicles - powered by renewable, low carbon electricity or hydrogen. Under the Renewable Portfolio Standard (RPS) the contribution of renewable sources to California's electricity generation mix will increase from 20 percent in 2010 to 33 percent in 2020. Likewise, SB1505 requires hydrogen transportation fuel in California to achieve a 30% reduction in GHG emissions per mile and include a 33% renewable component. The mutual policy goals of decarbonized transportation fuels and electricity generation will lead to a "convergence" of these two previously disparate energy sectors. Any effort to assess California's ability to achieve deep GHG emissions cuts from transportation will therefore require an integrated approach that considers such a convergence, understanding how best to share energy supply resources among both sectors and meet the combined demand for low-carbon, renewable energy they represent. In previous studies, Ryan McCarthy developed an hourly model of California's future electricity grid (LEDGE-CA) to investigate GHG emissions and cost impacts attributable to interactions between growing populations of electric-drive vehicles and the evolution of the electricity supply in California. This thesis aims to extend McCarthy's work in two key areas: quantifying renewable resources available for electricity and hydrogen fuel production in California and investigating the potential role of energy storage. Using geospatial and temporal analysis of planned and potential renewable electricity generation projects, this study develops a detailed assessment of the hourly renewable electricity supply in California that serves as an input into LEDGE-CA. Wind and solar energy are abundant renewable resources in California, yet their intermittency make them challenging to integrate into the electricity grid. Grid-energy storage options are evaluated to investigate how best to utilize wind and solar energy resources to meet electricity and hydrogen fuel demand. This study assesses the total potential for using renewable resources to produce fuel for electric and hydrogen vehicles in California and identifies potential strategy differences in terms of where and when to produce electricity and hydrogen fuels. Alternative pathways are compared with respect to cost, GHG emissions, energy demand, and transition issues.
