Available in PDF, EPUB and Kindle. Book excerpt: Biomass represents a large potential feedstock resource for environmentally clean processes that produce power or chemicals. It lends itself to both biological and thermal conversion processes and both options are currently being explored. Hydrogen can be produced in a variety of ways. The majority of the hydrogen produced in this country is produced through natural gas reforming and is used as chemical feedstock in refinery operations. In this report we will examine the production of hydrogen by gasification of biomass. Biomass is defined as organic matter that is available on a renewable basis through natural processes or as a by-product of processes that use renewable resources. The majority of biomass is used in combustion processes, in mills that use the renewable resources, to produce electricity for end-use product generation. This report will explore the use of hydrogen as a fuel derived from gasification of three candidate biomass feedstocks: bagasse, switchgrass, and a nutshell mix that consists of 40% almond nutshell, 40% almond prunings, and 20% walnut shell. In this report, an assessment of the technical and economic potential of producing hydrogen from biomass gasification is analyzed. The resource base was assessed to determine a process scale from feedstock costs and availability. Solids handling systems were researched. A GTI proprietary gasifier model was used in combination with a Hysys(reg. sign) design and simulation program to determine the amount of hydrogen that can be produced from each candidate biomass feed. Cost estimations were developed and government programs and incentives were analyzed. Finally, the barriers to the production and commercialization of hydrogen from biomass were determined. The end-use of the hydrogen produced from this system is small PEM fuel cells for automobiles. Pyrolysis of biomass was also considered. Pyrolysis is a reaction in which biomass or coal is partially vaporized by heating. Gasification is a more general term, and includes heating as well as the injection of other ''ingredients'' such as oxygen and water. Pyrolysis alone is a useful first step in creating vapors from coal or biomass that can then be processed in subsequent steps to make liquid fuels. Such products are not the objective of this project. Therefore pyrolysis was not included in the process design or in the economic analysis. High-pressure, fluidized bed gasification is best known to GTI through 30 years of experience. Entrained flow, in contrast to fluidized bed, is a gasification technology applied at much larger unit sizes than employed here. Coal gasification and residual oil gasifiers in refineries are the places where such designs have found application, at sizes on the order of 5 to 10 times larger than what has been determined for this study. Atmospheric pressure gasification is also not discussed. Atmospheric gasification has been the choice of all power system pilot plants built for biomass to date, except for the Varnamo plant in Sweden, which used the Ahlstrom (now Foster Wheeler) pressurized gasifier. However, for fuel production, the disadvantage of the large volumetric flows at low pressure leads to the pressurized gasifier being more economical.

Download or read book The Hydrogen Economy written by National Academy of Engineering and published by National Academies Press. This book was released on 2004-09-05 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2022-04-19 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 'Hydrogen Economy' is very broad subject ranging from the potential use of hydrogen for domestic use to the mass production of hydrogen replacing coal, natural gas (LNG) and conventional transport fuels.For any given project, there are many alternatives to consider for each stage of making, storing and transporting hydrogen. The book aims to assist proponents, and financiers of hydrogen projects to identify the optimum alternatives and identify hurdles and approaches to overcome them. This book attempts to describe an optimum approach to implement and its cost. It sets out to identify hurdles to implementation which may not be apparent to those entering the field for the first time.The book covers the various means and costs of production from fossil fuels (with carbon capture) - blue hydrogen - electrolysis - green hydrogen - or biomass. The book covers hydrogen storage as liquid or compressed gas and transport, through pipelines as liquid or by an intermediary fluid such as ammonia or a hydrocarbon. The book also discusses the production and costs of hydrogen delivery at the user end of a logistics chain. It also compares the relative energy value of energy delivered hydrogen versus the current suite of conventional fuels.

This book was released on 2013-02-26 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: In support of the U.S. Department of Energy (DOE) Advanced Research Program, conceptual systems and cost analyses were developed by the Parsons Corporation for coal processing plants to produce hydrogen while recovering carbon dioxide (CO2) for offsite processing or sequestration. These plants had been referred to as “decarbonized fuel plants,” but are now called “hydrogen fuel plants.” The scope of work for this analysis entailed the following: Identifying alternative processes and technologies utilized for production of hydrogen from coal; Reviewing the technical and economic characteristics of developmental materials and technologies for separating hydrogen and oxygen from gas mixtures; Conceptualizing process plant designs that utilize developing technologies and materials, resulting in costs of product and CO2 sequestration significantly lower than with conventional approaches; Comparing the costs of a hydrogen fuel plant with plants designed to produce hydrogen from coal utilizing conventional technology; Performing sensitivity analyses on the baseline conceptual hydrogen fuel plants to determine the effect of modifying plant design on cost of product; Presenting data and results on this study at periodic conferences and workshops. An alternative plant was conceived for producing hydrogen from coal utilizing a hydrogen separation device (HSD) being developed by Oak Ridge National Laboratory (ORNL). The HSD is based on a high-temperature membrane separation concept that can be designed to selectively separate hydrogen from other gases. By utilizing the HSD, it should be possible to separate hydrogen from CO2 passively and economically. This report is a compilation of a series of letter reports issued between 1999 and 2001 to document the activity and results from this investigation. It includes the following: An establishment of a baseline plant design for hydrogen production based on the ORNL membrane concept, A comparison of this design to the conventional methods of producing hydrogen from natural gas and coal, and An evaluation of the HSD based on gasifying a mixture of Wyodak coal and biomass.
Book Synopsis Hydrogen via Natural Gas Partial Oxidation - Cost Analysis - Hydrogen E12A by : Intratec

This book was released on 2019-09-17 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents a cost analysis of Hydrogen production from natural gas. The process examined is a typical partial oxidation process. In this process, natural gas passes through a thermal partial oxidation, generating carbon monoxide and hydrogen at ratios of approximately 2:1. In order to increase hydrogen output, the partial oxidation product is sent to a gas shift converter, to which steam is added to react with carbon monoxide, generating carbon dioxide and more hydrogen. Finally, the gaseous stream is purified in a pressure swing adsorber (PSA) and high-purity hydrogen is obtained. This report was developed based essentially on the following reference(s): "Hydrogen", Kirk-Othmer Encyclopedia of Chemical Technology, 5th edition Keywords: H2, NG, POX, Catalytic Partial Oxidation, Texaco, Shell

Book excerpt: A study was undertaken to evaluate the economics of producing hydrogen from coal and from water and to assess the market potential for this hydrogen in chemical and fuel applications. Results of this study are summarized. Current chemical applications of hydrogen in manufacturing ammonia and methanol, in refining petroleum and in specialty uses provide a base market for penetration by new hydrogen production technologies, although prospects for the use of hydrogen in fuel applications remain unclear. Electrolysis and coal gasification will be complementary, not competitive, technologies for producing hydrogen. Coal gasification plants are better suited to production of large quantities of hydrogen, while electrolyzers are better suited to the production of hydrogen for small-scale uses. Hydrogen produced through coal gasification may be economical in chemical applications (e.g., ammonia production) by the late 1990's. Development programs now underway are expected to provide new coal gasification technologies with lower first costs and higher efficiencies than current technologies. An on-site coal gasification plant supplying hydrogen in the quantities usually required in chemical applications (from 10 to 100 million cubic feet per day) will be smaller than is generally proposed for syngas plants. Growth in smaller scale specialty uses of hydrogen and improvements in the technology for electrolysis will create conditions favorable to expanded use of hydrogen produced through water electrolysis. The major constraint on use of electrolysis will be the availability of low cost electricity. Shortages of natural gas caused by declining domestic production could induce shifts to producing hydrogen through electrolysis or through coal gasification earlier in time (i.e., the late 1980's or early 1990's) than is suggested by comparative cost calculations alone.
