Book excerpt: The report describes the experience of the City of Houston in defining the compressed natural gas fueled vehicle research scope and issues. It details the ways in which the project met initial expectations, and how the project scope, focus, and duration were adjusted in response to unanticipated results. It provides examples of real world successes and failures in efforts to commercialize basic research in adapting a proven technology (natural gas) to a noncommercially proven application (vehicles). Phase one of the demonstration study investigates, develops, documents, and disseminates information regarding the economic, operational, and environmental implications of utilizing compressed natural gas (CNG) in various truck fueling applications. The four (4) truck classes investigated are light duty gasoline trucks, medium duty gasoline trucks, medium duty diesel trucks and heavy duty diesel trucks. The project researches aftermarket CNG conversions for the first three vehicle classes and original equipment manufactured (OEM) CNG vehicles for light duty gasoline and heavy duty diesel classes. In phase two of the demonstration project, critical issues are identified and assessed with respect to implementing use of CNG fueled vehicles in a large vehicle fleet. These issues include defining changes in local, state, and industry CNG fueled vehicle related codes and standards; addressing vehicle fuel storage limitations; using standardized vehicle emission testing procedures and results; and resolving CNG refueling infrastructure implementation issues and related cost factors. The report identifies which CNG vehicle fueling options were tried and failed and which were tried and succeeded, with and without modifications. The conclusions include a caution regarding overly optimistic assessments of CNG vehicle technology at the initiation of the project.

Natural gas vehicles (NGVs) can be dedicated to natural gas as a fuel source, or they can be bi-fuel, running on either natural gas or gasoline, or natural gas or diesel, although most natural gas engines are spark ignited. Natural gas engine technologies can differ in the following ways: the method used to ignite the fuel in the cylinders, the air-fuel ratio, the compression ratio, and the resulting performance and emissions capabilities. Natural gas has a high octane rating, which in spark ignition engines (usual for CNG) allows an increase in power. However, natural gas occupies a larger volume in the cylinder than liquid fuels, reducing the number of oxygen molecules (share of air in the cylinder), which reduces power. The net effect on natural gas power vs. gasoline is relatively neutral. However, since it is a gaseous fuel at atmospheric pressure and occupies a considerably larger storage volume per unit of energy than refined petroleum liquids, it is stored on-board the vehicle in either a compressed gaseous or liquefied state. The storage requirements are still much greater than for refined petroleum products. This increases vehicle weight, which tends to reduce fuel economy. To become compressed natural gas (CNG), it is pressurized in a tank at up to 3,600 pounds per square inch. Typically, in sedans, the tank is mounted in the trunk or replaces the existing fuel tank; on trucks, the tank is mounted on the frame; and on buses, it is mounted on top of the roof. Although tanks can be made completely from metal, they are typically composed of metal liners reinforced by a wrap of composite fiber material with pressure-relief devices designed to withstand impact. Tanks do increase the vehicle weight, and with the lower energy density of natural gas, vehicle ranges are generally reduced. To become liquefied natural gas (LNG), natural gas is cooled to -260 °F and filtered to remove impurities. LNG is stored in double-wall, vacuum-insulated pressure tanks and is primarily used on heavy-duty trucks, providing increased range over CNG. NGVs and their respective fueling systems must meet stringent industry and government standards for compression, storage, and fueling. They are designed to perform safely during both normal operations and crash situations. Nozzles and vehicle receptacles are designed to keep fuel from escaping.

This book was released on 2019-11-25 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: Technological Learning in the Transition to a Low-Carbon Energy System: Conceptual Issues, Empirical Findings, and Use in Energy Modeling quantifies key trends and drivers of energy technologies deployed in the energy transition. It uses the experience curve tool to show how future cost reductions and cumulative deployment of these technologies may shape the future mix of the electricity, heat and transport sectors. The book explores experience curves in detail, including possible pitfalls, and demonstrates how to quantify the 'quality' of experience curves. It discusses how this tool is implemented in models and addresses methodological challenges and solutions. For each technology, current market trends, past cost reductions and underlying drivers, available experience curves, and future prospects are considered. Electricity, heat and transport sector models are explored in-depth to show how the future deployment of these technologies—and their associated costs—determine whether ambitious decarbonization climate targets can be reached - and at what costs. The book also addresses lessons and recommendations for policymakers, industry and academics, including key technologies requiring further policy support, and what scientific knowledge gaps remain for future research. - Provides a comprehensive overview of trends and drivers for major energy technologies expected to play a role in the energy transition - Delivers data on cost trends, helping readers gain insights on how competitive energy technologies may become, and why - Reviews the use of learning curves in environmental impacts for lifecycle assessments and energy modeling - Features social learning for cost modeling and technology diffusion, including where consumer preferences play a major role

This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Compressed Natural Gas (CNG) is a practical automotive fuel, with advantages and disadvantages when compared to gasoline. Large quantities of natural gas are available in North America. It has a higher octane number rating, produces low exhaust emissions, no evaporative emissions and can cost less on an equivalent energy basis than other fuels. Natural gas is normally compressed from 20 684 to 24 821 kPa (3000 to 3600 psig) to increase its energy density thereby reducing its on-board vehicle storage volume for a given range and payload. CNG can also be made from liquefied natural gas by elevating its pressure and vaporizing it to a gas. Once converted it is referred to LCNG.The properties of natural gas are influenced by: (1) source of supply i.e. field, composition or impurities; (2) the processing of natural gas by the production and transmission companies; (3) the regional gas supply, storage, and demand balancing done by distribution companies often in concert with pipeline companies to maintain uninterrupted service throughout the year, e.g., peak shaving with propane-air (see U.S. Bureau of Mines Publication 503); and (4) dispensing site maintenance characteristics i.e. filtration and drying.The Coordinating Research Council (CRC) has published the results of a national compressed natural gas vehicle fuel survey. Information on the properties of distribution system natural gas and its variability has been included in Figure 1, 2, and 3, and can be found in CRC Report No. PC-2-12. Composition can vary hourly under certain operating conditions in certain areas of the country. Thus the data should generally be considered representative for the areas mentioned with due consideration for local variation.Natural gases transported throughout the U. S. are not subject to uniform national standards. Under federal government rules covering interstate sales of natural gas, the U. S. Federal Energy Regulatory Commission (FERC) adjudicates tariffs, placing economic and technical requirements upon natural gases entering interstate commerce. In 2006, FERC issued a policy statement advising stakeholders that: 1Only natural gas quality and interchangeability specifications contained in FERC-approved gas tariffs can be enforced; 2Pipeline tariff provisions on gas quality and interchangeability need to be flexible to allow pipelines to balance safety and reliability concerns; 3Pipelines and their customers should develop gas quality and interchangeability specifications based on technical requirements; 4In negotiating technically-based solutions, pipelines and their customers are strongly encouraged to use the Natural Gas Council Plus (NGC+) Interim Guidelinesas a common reference point for resolving gas quality and interchangeability issues; and 5To the extent pipelines and their customers cannot resolve disputes over gas quality and interchangeability, those disputes can be brought before FERC to be resolved on a case-by-case basis1The NGC+ Interim Guidelines call for natural gas specifications that include: 1A range of plus or minus 4% Wobbe number variation from local historical average gas, or alternatively, established adjustment or target gas for the service territory, subject to: aMaximum Wobbe number limit: 1400 bMaximum higher heating value limit: 1110 Btu/scf 2Additional composition maximum limits: aMaximum butanes+: 1.5 mole percent bMaximum total inerts: 4 mole percent 3EXCEPTION: Service territories with demonstrated experience with supplies exceeding these Wobbe, higher heating value and/or compositional limits may continue to use supplies conforming to this experience as long as it does not unduly contribute to safety and utilization problems of end use equipment.2While the Interim Guidelines provide only guidance for the setting of tariff limits on gas quality, experience has shown that in most cases the Wobbe and higher heating value limits are used in interstate tariffs. Since the bulk of U. S. sales of natural gas fall under FERC jurisdiction, this means that the Interim Guideline limits represent, in most cases, the limits that apply to natural gases received by distribution systems. Intrastate natural gas sales, by contrast, are not within FERC jurisdiction, but customers including utilities receiving gases from both intrastate and interstate sources, for practical purposes, generally receive natural gas that meets the Interim Guidelines.The NGC+ Interim Guidelines address combustion issues associated with natural gases. Separately, FERC considered condensable hydrocarbons in response to a second paper from NGC+.3 No specific actions were recommended by FERC in response to the NGC+ recommendations from this report, which basically recommended translation of historical condensable hydrocarbon experience into more general phase diagram-depicted "cricondentherm hydrocarbon dew point" (CHDP) criteria for higher hydrocarbon mixtures. CHDP criteria help ensure that natural gases of various compositions remain in gaseous state at all operating pressures and all reasonable ambient temperatures.Natural gas is comprised chiefly of methane (generally 88 to 96 mole percent) with the balance being a decreasing proportion of proportion of higher hydrocarbon alkanes such as ethane, propane, and butane. It can also contain nitrogen, water, carbon dioxide, oxygen, sulfur compounds and trace amounts of lubricating oil. At the retail outlet a warning agent, or odorant, is likely present in natural gas.Experience with natural gas vehicles has grown considerably. Fleet and ongoing in-use applications provide a foundation for characterizing gas composition factors that will help to understand gas quality effects on vehicle and overall performance and may cause fundamental operational problems for natural gas vehicles (NGVs). Water content and other corrosion precursors, heavier hydrocarbons, which may condense within the fuel container, particulate matter, oil, and energy content all need to be considered. Condensable hydrocarbons (liquid state) are also of concern in NGV equipment degradation. This Recommended Practice sets minimum requirements for compressed natural gas as a surface vehicle fuel for vehicle, engine, and component durability, operating safety, and design performance over the breadth of vehicle applications intended to utilize this fuel.

Available in PDF, EPUB and Kindle. Book excerpt: "The many alternative fuels that have been reviewed in this book are likely to be of great interest to a broad readership, not only to mechanical, petrochemical and transportation engineers, but anyone with a technical association with the subject. The book covers fuels for the motor vehicle and how they may develop and change in the future. Prospects for conventional petrol and diesel fuels are discussed, including their reformulation, as well as synthetic fuels, vegetable oils and other biofuels, alcohols, gases (LPG, natural gas and hydrogen) and electricity." "This book has been published as a consequence of a programme of study, commissioned by the Chief Mechanical Engineer's Office at the UK Department of Transport, into the contribution of the road vehicle to global warming. A programme of research was placed with the Environment Centre of the Transport Research Laboratory, and one of the individual projects was to investigate the future prospects for conventional and alternative fuels for road vehicles. Implications for the energy and emissions from the whole fuel cycle (from production to distribution and final usage) were considered, but, more importantly, the vehicular fuel consumption (and consequent carbon dioxide emissions) and exhaust emission characteristics were the primary focus of attention." "The structure of this book is such that each chapter describes a particular alternative fuel and is completely self-contained. The reader will be able to cover a particular subject that is of interest without having to refer to other chapters to gain a full understanding of the fuel's characteristics, notable developments and demonstration programmes underway worldwide. One chapter (chapter 10) does provide an overview and inter-comparison of all the fuels discussed, including point-of-use and life cycle emissions, global warming impacts, fuel storage implications and likely costs." "Future advances in conventional engines and the development of alternative power units are discussed in the companion volume to this book, Alternative Engines for Road Vehicles. The future prospects for a range of engines, including conventional petrol and diesel-fuelled units (covering technologies such as two-stroke, lean burn and stratified charge), the rotary engine, gas turbine, Stirling, Rankine (steam engine) and hybrids are assessed for their potential to reduce vehicle emissions and improve fuel economy. Other less well known concepts such as catalytic combustion, the Quadratic (beam) engine, stepped piston and other engine efficiency techniques are also reviewed." --Book Jacket.
