    2009-01-01

    Over the last twenty years, the consumption of natural gas in Korea has increased dramatically. This increase has mainly resulted from the rise of consumption in the residential sector. The main objective of the study is to estimate households' demand function for natural gas by applying a sample selection model using data from a survey of households in Seoul. The results show that there exists a selection bias in the sample and that failure to correct for sample selection bias distorts the mean estimate, of the demand for natural gas, downward by 48.1%. In addition, according to the estimation results, the size of the house, the dummy variable for dwelling in an apartment, the dummy variable for having a bed in an inner room, and the household's income all have positive relationships with the demand for natural gas. On the other hand, the size of the family and the price of gas negatively contribute to the demand for natural gas. (author)

    In the present process of the heat treatment of normalizing of the crystalline structure of cast metal pieces, the heating is made by electric resistance arranged on the inner surfaces of the side walls of a bell furnace. Although electrical heating is suitable to obtain a uniform generation on the walls covered with electrical resistances, and is easy to control and operate with virtually no gas flow, it has some disadvantages such as poor movement of the heated ambient air, and higher cost. Heating occurs mostly by thermal radiation, with direct exchange between the resistors and the heated parts, but with a part serving as a barrier to the other, and with greater difficulty of heating the core loading. The details presented in this study, will simulate the process of heating by using electricity and using natural gas. In these simulations will be observed the distribution of temperature in the load and indoor over time and the rate of energy transferred to the load and also for the outside so to have a comparative processes.

    2005-12-01

    A new approach for the detection of real-time properties of flames is used in this project to develop improved diagnostics and controls for natural gas fired furnaces. The system utilizes video images along with advanced image analysis and artificial intelligence techniques to provide virtual sensors in a stand-alone expert shell environment. One of the sensors is a flame sensor encompassing a flame detector and a flame analyzer to provide combustion status. The flame detector can identify any burner that has not fired in a multi-burner furnace. Another sensor is a 3-D temperature profiler. One important aspect of combustion control is product quality. The 3-D temperature profiler of this on-line system is intended to provide a tool for a better temperature control in a furnace to improve product quality. In summary, this on-line diagnostic and control system offers great potential for improving furnace thermal efficiency, lowering NOx and carbon monoxide emissions, and improving product quality. The system is applicable in natural gas-fired furnaces in the glass industry and reheating furnaces used in steel and forging industries.

  8. Impact of natural gas prices on Saskatchewan residential consumers : A report prepared for SaskEnergy

    International Nuclear Information System (INIS)

    1998-07-01

    Major trends in the natural gas industry, including deregulation and the impact of natural gas commodity competition on consumers, and SaskEnergy's current and historical residential rate structures were reviewed. The object of the exercise was to provide the Utility (i.e. SaskEnergy) with independent advice on the proposed changes to rate structures and billing practices for residential customers in Saskatchewan. It was concluded that SaskEnergy 's historical and current rate methodologies are consistent with generally accepted practices in the natural gas industry. The proposed changes to rate structures and billing practices to unbundle the gas commodity from delivery services is an important step in the evolution of competition in the supply of natural gas. Customers will not only have more choice in terms of supplier, they will be able to have a better understanding of both the impact of volatile commodity prices and any changes in the cost of delivery services on rates charged by SaskEnergy

    2014-01-01

    Background: Birth defects are a leading cause of neonatal mortality. Natural gas development (NGD) emits several potential teratogens, and U.S. production of natural gas is expanding. Objectives: We examined associations between maternal residential proximity to NGD and birth outcomes in a retrospective cohort study of 124,842 births between 1996 and 2009 in rural Colorado. Methods: We calculated inverse distance weighted natural gas well counts within a 10-mile radius of maternal residence to estimate maternal exposure to NGD. Logistic regression, adjusted for maternal and infant covariates, was used to estimate associations with exposure tertiles for congenital heart defects (CHDs), neural tube defects (NTDs), oral clefts, preterm birth, and term low birth weight. The association with term birth weight was investigated using multiple linear regression. Results: Prevalence of CHDs increased with exposure tertile, with an odds ratio (OR) of 1.3 for the highest tertile (95% CI: 1.2, 1.5); NTD prevalence was associated with the highest tertile of exposure (OR = 2.0; 95% CI: 1.0, 3.9, based on 59 cases), compared with the absence of any gas wells within a 10-mile radius. Exposure was negatively associated with preterm birth and positively associated with fetal growth, although the magnitude of association was small. No association was found between exposure and oral clefts. Conclusions: In this large cohort, we observed an association between density and proximity of natural gas wells within a 10-mile radius of maternal residence and prevalence of CHDs and possibly NTDs. Greater specificity in exposure estimates is needed to further explore these associations. Citation: McKenzie LM, Guo R, Witter RZ, Savitz DA, Newman LS, Adgate JL. 2014.

    2009-12-09

    An increasing share of natural gas supplies distributed to residential appliances in the U.S. may come from liquefied natural gas (LNG) imports. The imported gas will be of a higher Wobbe number than domestic gas, and there is concern that it could produce more pollutant emissions at the point of use. This report will review recently undertaken studies, some of which have observed substantial effects on various appliances when operated on different mixtures of imported LNG. While we will summarize findings of major studies, we will not try to characterize broad effects of LNG, but describe how different components of the appliance itself will be affected by imported LNG. This paper considers how the operation of each major component of the gas appliances may be impacted by a switch to LNG, and how this local impact may affect overall safety, performance and pollutant emissions.

    In order to have a standard for furnaces that includes electricity consumption or for the efficiency of furnace blowers to be determined, it is necessary to determine the airflow of a furnace or furnace blower. This study focused on airflow testing, in order to determine if an existing test method for measuring blower airflow could be used to measure the airflow of a furnace, under conditions seen in actual installations and to collect data and insights into the operating characteristics of various types of furnace blowers, to use in the analysis of the electricity consumption of furnaces. Results of the measured airflow on furnaces with three types of blower and motor combinations are presented in the report. These included: (1) a forward-curved blower wheel with a typical permanent split capacitor (PSC) motor, (2) a forward-curved blower wheel with an electronically-commutated motor (ECM), and (3) a prototype blower, consisting of a backward-inclined blower wheel matched to an ECM motor prototype, which is being developed as an energy-saving alternative to conventional furnace blowers. The testing provided data on power consumption, static and total pressure, and blower speed.

  13. Analyzing the Impact of Residential Building Attributes, Demographic and Behavioral Factors on Natural Gas Usage

    2011-03-03

    study attempts to bridge that gap by analyzing behavioral data and investigate the applicability of additive nonparametric regression to this task. This study evaluates the impact of 31 regressors on residential natural gas usage. The regressors include weather, economic variables, demographic and behavioral characteristics, and building attributes related to energy use. In general, most of the regression results were in line with previous engineering and economic studies in this area. There were, however, some counterintuitive results, particularly with regard to thermostat controls and behaviors. There are a number of possible reasons for these counterintuitive results including the inability to control for regional climate variability due to the data sanitization (to prevent identification of respondents), inaccurate data caused by to self-reporting, and the fact that not all relevant behavioral variables were included in the data set, so we were not able to control for them in the study. The results of this analysis could be used as an in-sample prediction for approximating energy demand of a residential building whose characteristics are described by the regressors in this analysis, but a certain combination of their particular values does not exist in the real world. In addition, this study has potential applications for benefit-cost analysis of residential upgrades and retrofits under a fixed budget, because the results of this study contain information on how natural gas consumption might change once a particular characteristic or attribute is altered. Finally, the results of this study can help establish a relationship between natural gas consumption and changes in behavior of occupants.

    The natural gas cogeneration offer is now available and operational in the industrial sector. It is based on technologies of piston engines and gas turbines. Currently, this offer is sufficiently diversified, so much from the point of view of the range of powers available (from 1 MW to more than 40 MW electric) that number of manufacturers. In order to widen the cogeneration market in France to the markets of the commercial and residential sectors, Gaz De France has undertaken a technical economic study to validate the potential of those markets. This study led to work on the assembly of a french die to cogeneration packages of low power (less than 1 MW electric). This step has emerged at the beginning of 1999 with the launching of a commercial offer of cogeneration packages. In margin to this work Gaz De France Research division also initiated a study in order to evaluate the offer of micro cogeneration, products delivering an electric output lower than 10 kW. (authors)

    Full Text Available (1 Background: The present paper aims at estimating the quality of the forecasts obtained by using one equation models. In particular, the focus is on the effect that the explanatory variables have on the forecasted quantity. The analysis is performed on the long term natural gas consumption in the Italian residential sector, but the same methodology can be applied to other contexts; (2 Methods: Different ex ante knowledge scenarios are built by associating different levels of confidence to the same set of explanatory variables. Forecasting results, coming from a standard regression algorithm and confirmed by a Kalman filter, are analyzed by means of covariance matrix propagation to assess the quality of the provided estimates; (3 Results: The outcomes show that one-equation models are very sensitive to the quality of the explanatory variables, therefore their erroneous estimation may have a relevant detrimental effect on the predictive accuracy of the model; (4 Conclusions: The overall ex ante forecasting accuracy of an example of one equation model is assessed. It has emerged that long-term forecasts need particular attention when the covered time horizon spans over decades. The information contained in the present paper is of interest for energy planners, supply network managers and policy makers in order to support their decisions.

    The aim of this work is to research operations of modern combined low-emission swirl burner with a capacity of 2.2 MW for fire-tube boiler type KV-GM-2.0, to ensure the effective burning of natural gas, crude oil and diesel fuel. For this purpose, a computer model of the burner and furnace chamber has been developed. The paper presents the results of numerical investigations of the burner operation, using the example of natural gas in a working load range from 40 to 100%. The basic features of processes of fuel burning in the cramped conditions of the flame tube have been identified to fundamentally differ from similar processes in the furnaces of steam boilers. The influence of the design of burners and their operating modes on incomplete combustion of fuel and the formation of nitrogen oxides has been determined.

    Relatively little information is available in the literature with respect to the performance of compressors used during the dynamic charging process of a tank. Therefore, work presented in this paper shows the measurement results of performance testing of a natural gas compressor and analyses the compressor characterization based on the experimental data. Initial tests were conducted using air and carbon dioxide given the thermodynamic similarities between these fluids and natural gas. Finally, a new test stand was specifically designed and built for compressor dynamic testing using pipeline natural gas (NG) and the compressor reliability has been evaluated inside an explosion-proof engine test cell. Reliability tests at standard operating conditions monitored the performance consistency of the compressors over the testing period and the testing consisted of a series of tank charges aimed at evaluating the maximum operating temperature as well as the mass flow rate in the system.

  1. Market power and the sale of Ontario residential natural gas: An institutional analysis and a laboratory experiment

    Science.gov (United States)

    Bloemhof, Barbara Lynn

    2005-11-01

    The Ontario residential natural gas market underwent a significant institutional change in 1986, after the federal government decontrolled natural gas prices. Currently, consumers may sign up for fixed-cost natural gas from a broker, or they may continue to be served by the regulated distribution company. This thesis examines the economic effects on consumers of the institutional change, and particularly whether or not market power was enhanced by the change. In the thesis, I first present the industrial organization of the residential natural gas sector, and explain the institutional evolution using an institutional economic approach. I then construct a model of the market environment, with sellers acting as middlemen in a well-defined Bertrand oligopoly setting with no production constraints and single-unit consumer demands. In this model, the only Nash equilibrium in the one-period game is the joint profit maximizing price, and its likelihood of obtaining depends on the nature of the cost of signing up new customers. I then take a version of this model into the laboratory with human subject sellers and simulated buyers and run six replications each of a balanced treatment design under a unique information mechanism that parallels individual customer canvassing used by sellers in the naturally-occurring market. Treatment variables are: number of sellers, number of simulated at-cost sellers present, and presence of input cost uncertainty for sellers. I find that adding any seller to the market has about the same impact on market price, irrespective of whether it is a human subject or a simulated at-cost seller. Although increasing the number of sellers does decrease the market price somewhat, it does not bring about the competitive outcome predicted by the benchmark microeconomic model. This research contributes to the literature on policy making and energy market design, as well as to experimental methodology aimed at policy evaluation.

    2010-01-01

    As part of its commitments to the Regional Greenhouse Gas Initiative (RGGI), the State of Maryland, USA, auctions emission permits to electric utilities, creating revenue that can be used to benefit consumers and the environment. This paper explores the CO 2 emissions reductions that may be possible by allocating some of that revenue to foster efficiency improvements in the residential sector's use of natural gas. Since these improvements will require changes to the capital stock of houses and end use equipment, efficiency improvements may be accompanied by economic and ancillary health impacts, both of which are quantified in this paper.

    The effect of liquefied natural gas on pollutant emissions was evaluated experimentally with used and new appliances in the laboratory and with appliances installed in residences, targeting information gaps from previous studies. Burner selection targeted available technologies that are projected to comprise the majority of installed appliances over the next decade. Experiments were conducted on 13 cooktop sets, 12 ovens, 5 broiler burners, 5 storage water heaters, 4 forced air furnaces, 1 wall furnace, and 6 tankless water heaters. Air-free concentrations and fuel-based emission factors were determined for carbon monoxide, nitrogen oxides, nitrogen dioxide, and the number of (predominantly ultrafine) particles over complete burns?including transient effects (device warm-up and intermittent firing of burners) following ignition--and during more stable end-of-burn conditions. Formaldehyde was measured over multi-burn cycles. The baseline fuel was Northern California line gas with Wobbe number (a measure of fuel energy delivery rate) of 1320-1340; test fuels had Wobbe numbers of roughly 1390 and 1420, and in some cases 1360. No ignition or operational problems were observed during test fuel use. Baseline emissions varied widely across and within burner groups and with burner operational mode. Statistically significant emissions changes were observed for some pollutants on some burners.

    With the cost of consuming resources increasing (both economically and ecologically), homeowners need to find ways to curb consumption. The Almanac of Minutely Power dataset Version 2 (AMPds2) has been released to help computational sustainability researchers, power and energy engineers, building scientists and technologists, utility companies, and eco-feedback researchers test their models, systems, algorithms, or prototypes on real house data. In the vast majority of cases, real-world datasets lead to more accurate models and algorithms. AMPds2 is the first dataset to capture all three main types of consumption (electricity, water, and natural gas) over a long period of time (2 years) and provide 11 measurement characteristics for electricity. No other such datasets from Canada exist. Each meter has 730 days of captured data. We also include environmental and utility billing data for cost analysis. AMPds2 data has been pre-cleaned to provide for consistent and comparable accuracy results amongst different researchers and machine learning algorithms.

    2005-01-01

    This PowerPoint presentation examined challenges in the economic valuation of environmental changes within the context of formal real estate markets. It was proposed that some values that are expressed in markets can be affected by environmental changes and should be used in resource development land assessments. Details of indirect market valuation and revealed preference methods were reviewed. An outline of hedonic pricing was presented. It was noted that hedonic pricing can be used with other market values and prices such as tourism, art prices and hotel prices, where multivariate regression techniques are used and regression coefficients reveal information on the implicit prices of certain characteristics. Property value examples in the environmental economics literature were reviewed. A case study using data from eco-terrorism costs was presented. Issues concerning sour gas facilities were discussed with reference to public anxiety over hydrogen sulfide (H 2 S) toxicity and flares. Concerns over health risks and negative amenity impacts were discussed. The impacts of sour gas facilities on property values of residential acreages in and around Calgary were considered, and a map of the study area was presented. An outline of emergency plan response zones was provided. Price effects of industry facilities were presented, including marginal and cumulative impacts on price. It was concluded that oil and gas activities have significant impacts on rural residential property prices, but that industry members currently report that there is little to no effect. It was suggested that the research presented in this paper could be used to assess levels of compensation. tabs., figs

    The continual increases in energy demand and greenhouse gas emissions, call for efficient use of energy resources. Decentralized combined heat and power (CHP) technology provides an alternative for the world to meet and solve energy-related problems including energy shortages, energy supply security, emission control and conservation of energy. This paper presents the preliminary results of an experimental investigation of a natural gas-fired micro-CHP system for residential buildings based on an organic Rankine cycle (ORC). Isopentane was used as the ORC working fluid in consideration of several criteria including its environmentally-friendly characteristics. Experiments were conducted to evaluate the performance of the developed system at different heat source temperatures of nominally 85, 80, 75, 70, and 65 °C. The maximum electrical power output of 77.4 W was generated at heating water entry temperature of 84.1 °C, corresponding to net cycle electrical efficiency of 1.66%. Further work will be done with a view to increasing the cycle electrical efficiency by using more efficient components, in particular the expander and generator. - Highlights: •A natural gas-fired ORC-based micro-scale CHP system has been developed and tested. •The good agreement between the mechanical and gross power validates the assumptions. •A vane expander suits a micro-CHP system based on an organic Rankine cycle. •A vane expander does not suit power generation by a Trilateral Flash Cycle (TFC). •Domestic gas-fired ORC systems may reduce reliance on central power stations

    With the proliferation of statewide energy savings targets and other policies favorable to energy efficiency, savings from utility customer-funded energy efficiency programs could rise to offset much of annual load growth by 2025 (Barbose et al 2013). For these increased savings to occur, however, nearly all of these programs must pass screening for cost effectiveness. Some program administrators and state regulators are finding that conventional analyses, which only consider a narrow set of energy-savings related efficiency program benefits, are now resulting in some natural gas efficiency programs failing their cost-effectiveness criteria in the new low natural gas price environment. Regulators are considering whether to scale back or terminate gas portfolios in at least four states (WA, OR, ID, NM) because of cost-effectiveness concerns. Stakeholders in several regions of the country have asked LBNL to help assess alternatives to reducing the pursuit of energy savings in their regions. We address these requests by producing two working papers: one exploring cost-effectiveness screening policy implications of low to moderate natural gas prices, and a second assessing some of the values that policymakers may take into account in weighing the pros and cons of ending natural gas efficiency programs. In this policy brief, we lay out the challenges that low gas prices pose for cost effectiveness of an electric-gas efficiency program and portfolio. We then quantify options available to regulators and administrators who want to evaluate the tradeoffs among multiple policy objectives. A multi-measure, residential energy upgrade program in the Midwest is used as a lens to explore the implications of common and emerging cost-effectiveness policies in the context of low prices for natural gas. We illustrate the results across a range of cost-effectiveness screening options, including different discount rates, levels of test application, various benefit-cost tests, and the

    Air samples were collected in a typical residential and commercial area in Rio de Janeiro, Brazil, where buses and trucks use diesel and light duty vehicles use compressed natural gas, ethanol, and gasohol (gasoline blended with ethanol) as fuel. A total of 66 C3-C12 volatile organic compounds (VOCs) were identified. The most abundant compounds, on a mass concentration basis, included propane, isobutane, i-pentane, m,p-xylene, 1,3,5-trimethylbenzene, toluene, styrene, ethylbenzene, isopropylbenzene, o-xylene and 1,2,4-trimethylbenzene. Two VOCs photochemical reactivity rankings are presented: one involves reaction with OH and the other involves production of ozone.

  16. Development of a test set for adjustment of residential furnaces and boilers. Final report

    A program was undertaken to design and develop a portable test set for simplified field adjustment of residential furnaces and boilers to achieve peak operating efficiency. Advanced technology was applied to provide continuous analysis of flue gases and the display of temperature, oxygen concentrations, smoke value and furnace efficiency. Prototype models were constructed and delivered to Brookhaven National Laboratory for further testing. A survey of furnace dealers was conducted, and a commercialization plan was developed based on survey responses and the status of the equipment developed under the program. Goals for a marketable test set and development steps to achieve a projected energy savings were determined and recommended. Recommendations for specific areas of further development are included.

    New single-family home construction represents a significant and important market for the introduction of energy-efficient gas-fired space heating and water-heating equipment. In the new construction market, the choice of furnace and water-heater type is primarily driven by first cost considerations and the availability of power vent and condensing water heaters. Few analysis have been performed to assess the economic impacts of the different combinations of space and water-heating equipment. Thus, equipment is often installed without taking into consideration the potential economic and energy savings of installing space and water-heating equipment combinations. In this study, we use a life-cycle cost analysis that accounts for uncertainty and variability of the analysis inputs to assess the economic benefits of gas furnace and water-heater design combinations. This study accounts not only for the equipment cost but also for the cost of installing, maintaining, repairing, and operating the equipment over its lifetime. Overall, this study, which is focused on US single-family new construction households that install gas furnaces and storage water heaters, finds that installing a condensing or power-vent water heater together with condensing furnace is the most cost-effective option for the majority of these houses. Furthermore, the findings suggest that the new construction residential market could be a target market for the large-scale introduction of a combination of condensing or power-vent water heaters with condensing furnaces.

    The opening of energy markets to competition became effective to individuals ('residential clients') on July 1, 2007 with the possibility to freely choose their energy supplier. This opening of energy markets to residential clients started 3 years after the opening to professionals (July 1, 2004). The Commission of energy regulation (CRE) and the national energy Ombudsman have set in place in 2007 a quantitative yearly survey ('barometer') addressed to residential clients in order to collect statistical data about the behaviour of these clients with regards to the opening of markets to competition. This document deals with the results of the fourth run of this survey carried out in September 2009 by the LH2 institute. For the 1500 households investigated, LH2 has questioned the person in charge of the energy bills management. The barometer aimed at answering the following questions: - what is the level of knowledge and information of residential clients about markets opening and the existing regulation? - What perception of this opening do they have? (pros/cons, advantages/drawbacks); - what behaviour do they have in front of the opening of markets to competition? (approach with respect to information needs, knowledge about the offer, intention to change supplier, brakes/motivations in entering the open market). (J.S.)

    This article aims to evaluate the performances of an adsorption system driven thanks to the heat rejected by the post-combustion exhaust gases of a reformer/fuel cell system for residential air-conditioning application. Three adsorption pairs were compared: activated carbon/methanol, silica gel/water and zeolite/water. Taking into account both cooling power and sensitivity to performances of the heat rejection and recovery exchangers, it appears that zeolite 13X/water is the adsorption pair giving the best performance for this application. Nevertheless, a more detailed model would be of interest to better quantify the heat transfer impact on performance. (author)

    One of the major obstacles to the successful development and commercialization of a coal-fired residential furnace is the need for a reliable, cost-effective emission control system. Tecogen is developing a novel, integrated control system to control NO{sub x}SO{sub 2}, and particulate emissions. At the heart of this system is a unique emissions control reactor for the control of SO{sub 2}. This reactor provides high sorbent particle residence time within the reactor while doing so in a very compact geometry. Final cleanup of any fine particulates exiting the reactor including respirable-sized particulates, is completed with the use of high efficiency bag filters. Under a previous contract with PETC (Contract No. DE-AC22-87PC79650), Tecogen developed a residential-scale Coal Water Slurry (CWS) combustor to control NO{sub x}emission. This combustor makes use of centrifugal forces, set up by a predominantly tangential flow field, to separate and confine larger unburned coal particles in the furnace upper chamber. Various partitions are used to retard the axial, downward flow of these particles, and thus maximize their residence time in the hottest section of the combustor. By operating this combustor under staged conditions, the local stoichiometry in the primary zone can be controlled in such a manner as to minimize NO{sub x} emission.

    The procedure for and results of a test study of polycyclic aromatic hydrocarbon (PAH) emission from a few types of solid fuels combustion in residential furnaces of various designs typical for Belarus are discussed. Greatest levels of PAH emission were detected from domestic wastes and wood waste combustion. Lowest levels of PAH emission are from peat briquette combustion. It was found that PAH concentration in off-gases from firewood combustion also varies significantly depending on the type of wood: the highest values of PAH are typical for waste gases from birch firewood combustion in comparison with pine firewood combustion. Draft PAH emission factors are proposed with intended application for emission inventory of such installations

    This issue of the Natural Gas Monthly presents the most recent estimates of natural gas data from the Energy Information Administration. Estimates extend through November for many data series, and through August for most natural gas prices. Highlights of the most recent data estimates are: (1) Preliminary estimates of dry natural gas production and total consumption available through November 1997 indicate that both series are on track to end the year at levels close to those of 1996. Cumulative dry production is one-half percent higher than in 1996 and consumption is one-half percent lower. (2) Natural gas production is estimated to be 52.6 billion cubic feet per day in November 1997, the highest rate since March 1997. (3) After falling 8 percent in July 1997, the national average wellhead price rose 10 percent in August 1997, reaching an estimated $2.21 per thousand cubic feet. (4) Milder weather in November 1997 compared to November 1996 has resulted in significantly lower levels of residential consumption of natural gas and net storage withdrawls than a year ago. The November 1997 estimates of residential consumption and net withdrawls are 9 and 20 percent lower, respectively, than in November 1996.

    Full Text Available Since April 1, 2015, for those non-residential gas users, the stock gas and incremental gas prices have been unified, and direct-supply gas prices have been released. This means that natural gas pricing reform has entered a new stage of development in China. In view of this, we first summarized and analyzed the achievements, status quo and existing problems in natural gas pricing reform in recent years in China. Then, we made an overview on the global natural gas pricing and marketing experiences and domestic situation in natural gas sector. On this basis, we presented the following proposals and implement approaches to ultimately achieving the market-oriented reform of natural gas pricing in China. First, the ex-factory prices for those residential gas users will be adjusted, which should be differentiated from those for the non-residential gas users. Second, the present natural gas pricing mechanism should be perfected with pipeline fees and gas storage fees being both added. Third, an integrated natural gas pricing system should be improved with differential prices implemented. Fourth, natural gas spot transaction should be promoted and energy measurement in gas metering and pricing should also be put into practice.

    In 2010, natural gas provided 54% of total residential space heating energy the U.S. on a source basis, or 3.5 Quadrillion Btu. Natural gas burned in furnaces accounted for 92% of that total, and boilers and other equipment made up the remainder. A better understanding of installed furnace performance is a key to energy savings for this significant energy usage. In this project, the U.S. Department of Energy Building America team Partnership for Advanced Residential Retrofit examined the impact that common installation practices and age-induced equipment degradation may have on the installed performance of natural gas furnaces over the life of the product, as measured by steady-state efficiency and annual efficiency. The team identified 12 furnaces of various ages and efficiencies that were operating in residential homes in the Des Moines, Iowa, metropolitan area and worked with a local heating, ventilation, and air conditioning contractor to retrieve furnaces and test them at the Gas Technology Institute laboratory for steady-state efficiency and annual efficiency. Prior to removal, system airflow, static pressure, equipment temperature rise, and flue loss measurements were recorded for each furnace as installed in the house.

    1997-01-01

    Despite having proven reserves equal to that of North America, natural gas has traditionally played a minor role in the energy policies of Latin American countries, being considered secondary to oil. There has, therefore, been a neglect of the sector with a resultant lack of an adequate infrastructure throughout the region, perhaps with the exception of Argentina. However, with a massive increase in energy demand, growing concerns with environmental matters and a need to reduce the massive pollution levels in major cities in the region, natural gas is forecast to play a much greater role in Latin America's energy profile, with final consumption forecast to rise at 5.4% per annum for the next 15 years. This book assesses both the development of the use of natural gas in the power industrial sector and proposals for its growth into the residential, commercial and transport sectors. It analyses the significant investment required and the governments' need to turn to the private sector for investment and innovation. Natural Gas in Latin America analyses the possibilities and pitfalls of investing in the sector and describes the key trends and issues. It analyses all aspects of the gas industry from exploration and production to transportation and distribution to end users. (Author)

    1998-01-01

    An overview of natural gas markets in Canada and in the United States was provided. The major factors that determine the direction of natural gas prices were depicted graphically. Price volatility has decreased in recent months. As expected, April through November total energy consumption reached historically high levels. Demand for natural gas during the summer of 1997 was not as strong as anticipated. Nuclear energy appears to be on the slippery slope, with natural gas-driven electricity projects to fill the void. Hydroelectricity had a strong showing in 1997. Prospects are less bright for 1998 due to above average temperatures. Canadian natural gas export capacity has increased 5.5 times between 1986 and estimated 1999 levels. Despite this, in 1997, deliveries to the United States were marginally behind expectations. Natural gas consumption, comparative fuel prices, natural gas drilling activity, natural gas storage capacity, actual storage by region, and average weekly spot natural gas prices, for both the U. S. and Canada, were also provided. With regard to Canada, it was suggested that Canadian producers are well positioned for a significant increase in their price realization mostly because of the increase in Canada's export capacity in 1997 (+175 Mmcf/d), 1998 (1,060 Mmcf/d) and potentially in 1999 or 2000, via the Alliance Pipeline project. Nevertheless, with current production projections it appears next to impossible to fill the 10.9 Bcf/d of export capacity that will be potentially in place by the end of 1999. tabs., figs

  10. British Columbia natural gas: Core market policy

    International Nuclear Information System (INIS)

    1988-06-01

    The core market for natural gas in British Columbia is defined as all natural gas consumers in the residential, institutional, commercial, and industrial sectors not currently purchasing natural gas directly and not exempted from the core market by the British Columbia Utilities Commission (BCUC). The intent of the definition is to include all customers who must be protected by contracts which ensure long-term security of supply and stable prices. Core market customers are excluded from direct natural gas purchase and will be served by distribution utilities. A customer may apply to BCUC to leave the core market; such an application may be approved if it is demonstrated that the customer has adequate long-term natural gas supplies or alternative fuel supplies to protect him from supply interruptions. The non-core market is defined as all large industrial customers who elect to make their own natural gas supply arrangements and who can demonstrate to the BCUC sufficient long-term natural gas supply protection or alternative fuel capability to ensure security of the industry. Non-core market customers have full and open access to the competitive natural gas market. The British Columbia government will not apply its core market policy to other jurisdictions through Energy Removal Certificates

    A series of overhead viewgraphs accompanied this presentation which focused on various aspects of the natural gas industry in Mexico. Some of the viewgraphs depicted statistics from 1998 regarding natural gas throughput from various companies in North America, natural gas reserves around the world, and natural gas reserves in Mexico. Other viewgraphs depicted associated and non-associated natural gas production from 1988 to 1998 in million cubic feet per day. The Burgos Basin and the Cantarell Basin gas production from 1997 to 2004 was also depicted. Other viewgraphs were entitled: (1) gas processing infrastructure for 1999, (2) cryogenic plant at Cd. PEMEX, (3) average annual growth of dry natural gas production for 1997-2004 is estimated at 5.2 per cent, (4) gas flows for December 1998, (5) PGPB- interconnect points, (6) U.S. Mexico gas trade for 1994-1998, (7) PGPB's interconnect projects with U.S., and (8) natural gas storage areas. Technological innovations in the industry include more efficient gas turbines which allow for cogeneration, heat recovery steam generators which reduce pollutant emissions by 21 per cent, cold boxes which increase heat transfer efficiency, and lateral reboilers which reduce energy consumption and total costs. A pie chart depicting natural gas demand by sector shows that natural gas for power generation will increase from 16 per cent in 1997 to 31 per cent in 2004. The opportunities for cogeneration projects were also reviewed. The Comision Federal de Electricidad and independent power producers represent the largest opportunity. The 1997-2001 investment program proposes an 85 per cent sulphur dioxide emission reduction compared to 1997 levels. This presentation also noted that during the 1998-2001 period, total ethane production will grow by 58 tbd. 31 figs

    1996-01-01

    This article presents compressed natural gas for vehicles (CNG), which can provide considerable advantages both as an alternative fuel and as a clean fuel. These assets are not only economic but also technical. The first part deals with what is at stake in developing natural gas as a motor fuel. The first countries to use CNG were those with natural gas resources in their subsoil. Today, with a large number of countries having to cope with growing concern about increasing urban pollution, natural gas is also seen as a clean fuel that can help cut vehicle pollutant emissions dramatically. In the second part a brief technical descriptions is given of CNG stations and vehicles, with the aim of acquainting the reader with some of CNG's specific technical features as compared to gasoline and diesel oil. Here CNG technologies are seen to be very close to the more conventional ones. (author)

    The General Auditor in the Netherlands studied the natural gas policy in the Netherlands, as has been executed in the past decades, in the period 1997-1999. The purpose of the study is to inform the Dutch parliament on the planning and the backgrounds of the natural gas policy and on the policy risks with respect to the benefits for the Dutch State, taking into account the developments in the policy environment. The final conclusion is that the proposed liberalization of the national natural gas market will result in a considerable deprivation of income for the State in case the benefit policy is not adjusted. This report includes a reaction of the Dutch Minister of Economic Affairs and an afterword of the General Auditor. In the appendix an outline is given of the natural gas policy

  20. Natural gas pricing

    International Nuclear Information System (INIS)

    Freedenthal, C.

    1993-01-01

    Natural gas pricing is the heart and soul of the gas business. Price specifically affects every phase of the industry. Too low a price will result in short supplies as seen in the mid-1970s when natural gas was scarce and in tight supply. To fully understand the pricing of this energy commodity, it is important to understand the total energy picture. In addition, the effect and impact of world and US economies, and economics in general are crucial to understanding natural gas pricing. The purpose of this presentation will be to show the parameters going into US natural gas pricing including the influence of the many outside industry factors like crude oil and coal pricing, market drivers pushing the gas industry, supply/demand parameters, risk management for buyers and sellers, and other elements involved in pricing analysis

    International Nuclear Information System (INIS)

    Freedenthal, C.

    1993-01-01

    In recent years, natural gas has gained new momentum because of changes in marketing and regulations. The gas industry has always received an inordinate amount of regulatory control starting at the well head where the gas is produced to the consuming burner tip. Regulations have drastically impacted the availability of gas. Changes in the marketing and regulations have made the natural gas market sensitive at the point of production, the well head. Now, with plentiful supply and ease of transportation to bring the gas from the producing fields to the consumer, natural gas markets are taking advantage of the changed conditions. At the same time, new markets are developing to take advantage of the changes. This section shows consumers, especially the energy planners for large buyers of fuel, the advantages, sources and new methods of securing natural gas supplies. Background on how natural gas is produced and marketed are given. This section lists marketing sources, regulatory agencies and information groups available to help buyers and consumers of this important fuel for US industries and residences. 7 figs., 8 tabs

    Storage is an important link in the natural gas supply chain. It is a valuable aid to providing the link between remote sources of production and consumption locations. After a brief recall covering the role of storage this article describes the various options for storing natural gas: saline cavities, aquifers, liquefied gas tanks or artificial cavities. A report follows on the different solutions adopted in Europe and in Switzerland, more particularly that chosen by Gaznat in order to contribute to securing supplies in Western Switzerland. Market deregulation has brought changes to the regulations, which are in turn modifying the rules that were in force until just recently, and new topics are arising, such as strategic reserves and pricing rules for stored natural gas.

    This paper reviews the growing power and economic strength of Enron Corp., a natural gas distributor and exploration company. The paper reviews the policy of the company to exploit deregulation at home and privatization of all sorts of energy companies abroad. Enron is actively building its own power plants in the US and has successfully boosted their profits by 20 percent in what was considered a flat natural gas market. The paper goes on to discuss the company's view of the new energy tax and how it should benefit natural gas companies as a whole. Finally the paper reviews the contracting procedures of the company to secure long-term fixed price contracts in a volatile market which precludes most companies from taking the risk

  11. Canadian natural gas

    International Nuclear Information System (INIS)

    Lucas, D.A.

    1991-01-01

    Canada's natural gas industry enjoys a quiet confidence as it looks ahead to the 1990s. In this paper, the author explains why, despite some critical uncertainties, the optimism endures. Reviewing the current conditions of supply, production, consumption, pipelines, and pipeline expansion plans, the author contends that the New World of the 1990s will belong to natural gas. The author's assessment of natural gas markets proceeds far beyond the borders of Canada. The author examines the determinants of gas prices throughout North America and he identifies the one force that promises to seize almost complete control of gas prices throughout the continent. While the analysis points out the attributes of this new pricing regime, it also names the obstacles that could prevent this emerging mechanism from assuming its anticipated position

    2015-01-01

    In order to accomplish significant primary energy saving and GHG (greenhouse gas) emissions reduction, CHP (combined heat and power) technology can be adopted largely for industrial and civil sectors. Waiting for the cutting-edge appliances (i.e. Fuel Cell) wide deployment, ICEs (internal combustion engines) fuelled with an environmentally-friendly fuel, such as H 2 NG (hydrogen-natural gas mixtures) could represent the bridge technology towards the forthcoming pure hydrogen economy. This paper deals with the results of an experimental campaign carried out on a Single Cylinder ICE, fuelled with NG (natural gas) and H 2 NG @ 15% vol. In detail, energy performances were assessed at rated and partial loads. From data analysis, it emerged that the electrical efficiency increased up to 2.28%, at the expense of the heat recovery one, having added hydrogen. Additionally, due to the higher water content in exhaust gas when H 2 NG is burned, it was investigated on how heat recovery efficiency has been affected by condensing operating conditions. Finally, to estimate this benefit, an expeditious procedure was developed building three maps for H 2 NG blends condensing properties from 0% up to 30% vol. of H 2 . Their outputs provided the condensation efficiency value and the absolute gain of heat recovery one with varying exhaust gas temperatures and hydrogen fraction in the mixture. - Highlights: • H 2 NG mixture effects on a commercial technology μCHP for residential applications. • Experimental analysis and methodology for H 2 NG condensing properties assessment. • CO 2 specific emissions calculation accounting for electrical and thermal outputs. • Uncertainty analysis on the μCHP energy performances and methodology validation. • H 2 addition coupling a condensing heat exchanger enhance CHP First Law efficiency

    Lutz, James; Lekov, Alex; Chan, Peter; Whitehead, Camilla Dunham; Meyers, Steve; McMahon, James

    2006-01-01

    In 2001, the US Department of Energy (DOE) initiated a rulemaking process to consider whether to amend the existing energy efficiency standards for furnaces and boilers. A key factor in DOE's consideration of new standards is the economic impacts on consumers of possible revisions to energy-efficiency standards. Determining cost-effectiveness requires an appropriate comparison of the additional first cost of energy efficiency design options with the savings in operating costs. DOE's preferred approach involves comparing the total life-cycle cost (LCC) of owning and operating a more efficient appliance with the LCC for a baseline design. This study describes the method used to conduct the LCC analysis and presents the estimated change in LCC associated with more energy-efficient equipment. The results indicate that efficiency improvement relative to the baseline design can reduce the LCC in each of the product classes considered

    Turner, R.

    2004-01-01

    This presentation reviewed natural gas supply and demand issues facing Ontario and outlined TransCanada's role as a key player in Ontario's energy industry. TransCanada's gas transmission assets include 39,000 km of wholly owned pipelines from British Columbia to Atlantic Canada that carry 11 Bcf of gas per day. In addition, TransCanada operates 29 power generating plants, of which 6 are in Ontario. The company is also involved the proposed Mackenzie Valley and Alaska pipeline. A map illustrating Ontario and Quebec operations was included along with graphs depicting the 2004 base case for North American gas demand by region. Historical and forecasted gas demand by end use sector in Ontario and Quebec was also illustrated. A chart of North American gas supply indicates that new supply is needed to meet energy demands. Production forecasts for Western Canada for conventional and unconventional reserves indicates that by 2015, unconventional reserves such as coalbed methane (CBM) will make up a larger portion of the production mix. A map indicating existing and proposed import terminals along the Atlantic and Pacific coasts for liquefied natural gas (LNG) was included. The challenges facing the North American gas market include price volatility, the need to update energy policies, the need to improve regulatory efficiency, and aligning the interests of market participants. It was concluded that although natural gas from Western Canada will continue to be a stable supply source for many years, the natural gas market in North America is seeking new supply in frontier gas, LNG and CBM to meeting growing demand. 1 tab., 11 figs

  19. Short-term outlook for natural gas and natural gas liquids to 2006 : an energy market assessment

    International Nuclear Information System (INIS)

    2005-10-01

    In recent years, natural gas markets in North America have seen a close balance between supply and demand, resulting in high and volatile natural gas prices. The National Energy Board monitors the supply of all energy commodities in Canada along with the demand for Canadian energy commodities in domestic and export markets. This is the NEB's first energy market assessment report that presents a combined short-term analysis and outlook of natural gas and natural gas liquids (NGLs), such as ethane, propane and butane. It provides comprehensive information on the complexity of natural gas and NGL industries and highlights recent developments and topical issues. As a major producer of natural gas, western Canada has a correspondingly large natural gas processing capability that was developed specifically to extract NGLs. A world-scale petrochemical industry was developed in Alberta to convert NGLs into even higher valued products such as ethylene. Since NGLs in Canada are sourced mostly from natural gas, changes to the supply and demand for natural gas would impact NGL supply. This report addressed the issue of commodity prices with reference to crude oil, natural gas and NGL prices. Natural gas supply in terms of North American production and natural gas from coal (NGC) was also reviewed along with natural gas demand for residential and commercial heating, industrial use, power generation, and enhanced recovery for oil sand operations. There are about 692 gas plants in Canada that process raw natural gas into marketable gas and NGLs. Most are small field plants that process raw natural gas production to remove impurities such as sulphur, water and other contaminants. This report also discussed this infrastructure, with reference to field plants, straddle plants, pipelines, distribution and storage, including underground NGL storage. 3 tabs., 27 figs., 5 appendices

    Natural gas is a relatively clean fossil fuel for space heating. However, when it is not used efficiently high consumption can become an environmental problem. In Argentina, individual balanced-flue space heaters are the most extensively used in temperate and cold regions. This furnace is a simple device with a burner set into a metal chamber, separated from the indoor ambient by an enclosing cabinet, and both inlet and outgas chimneys are connected to the outdoor ambient. In previous studies, we measured the performance of these commercial devices, and found very low thermal efficiency (in the range of 39-63% depending on the chimney configuration). The extensive use of these devices is possible due to the availability of unlimited amount of subsidised natural gas to households and businesses. In the present work, we developed a prototype with simple and low cost modifications made on commercial models, and measured the improvements on the thermal efficiency. Findings showed better infrared radiation, enhanced indoor air convection, and passive chimney flow regulation leading to thermal efficiency in the range of 75-85%. These values represent an improvement of 100% when compared to marketed models, and hence, the specific cost of the heater per unit of useful heating power delivered was actually reduced. Considering the large market presence of these furnaces in both residential and business sectors in Argentina, the potential benefits related to gas consumption and environmental emissions are very significant.

    Recent projection of the market in global scale shows a tendency in natural gas using replacing mostly the fuel oil. Its market share well increase from 21.1% in 1994 to 24.0% in 2010. The annual energetic use will reach 29.23 x 10{sup 9} Gcal in 2010 (8990 million Nm{sup 3} natural gas/day) versus 18.90 x 10{sup 9} Gcal in 1994 (5810 million Nm{sup 3} natural gas/day). For Brazil, its consumption will increase from 8.7 million Nm{sup 3} natural gas/day in 1994 to 35.9 million Nm{sup 3} natural gas/day in 2010. Projects like Brazil-Bolivia natural gas pipeline, will supply 18 million Nm{sup 3} natural gas/day, which expected to start-up before the year 2000. This projects will supply the Brazilian southern regions, that do not consume natural gas at the current moment. Although there are many different kind of natural gas consumption in the industry this paper presents the technical and economical estimate of the injection in the blast furnace operating with coke or charcoal. The process simulation is done assisted by math modeling developed by White Martins/Praxair Inc. (author)

    Natural gas has a very good potential compared to other fossil fuels as regard to global warming because of its high content of hydrogen, and its versatility in uses. To take full advantage of this potential, further development of gas designed boilers and furnaces, gas catalytic combustion, fuel cells are needed, but progresses in the recent years have been very promising. The natural gas industry' environmental potential is discussed. Regarding methane emission, progresses have been done is Western Europe on the distribution network, and some improvement are underway. It is however important to rationalize the effort by acting on the most emitting subsystem: this can be achieved by cooperation along the whole gas chain. (R.P.)

    The technology of compressed natural gas (CNG) for road vehicles originated 50 years ago in Italy, always able to adapt itself to changes in energy supply and demand situations and national assets. Now, due to the public's growing concern for air pollution abatement and recent national energy policies calling for energy diversification, the commercialization of natural gas road vehicles is receiving new momentum. However, proper fuel taxation and an increased number of natural gas distribution stations are required to support this growing market potential. Operators of urban bus fleets stand to gain substantially from conversion to natural gas automotive fuels due to natural gas being a relatively cheap, clean alternative

    As low carbon-emitting fossil fuel, the natural gas is mainly used for power generation and industrial applications. It is also used for heating and cooling in commercial and residential buildings as well as in transport industry. Although the natural gas reaches the end-user mainly through pipelines (if gas is available locally), the liquefied form is the most viable alternative to transport natural gas from far away location to the end user. The economic progress in Asia and other parts of the world creates huge demand for energy (oil, gas and coal). As low carbon-emitting fuel, the demand for gas especially in liquefied form is progressively rising. Having 7th largest shale gas reserve (437 trillion cubic feet recoverable), Australia has become one of the world's major natural gas producers and exporters and is expected to continue a dominating role in the world gas market in foreseeable future. This paper reviews Australia's current gas reserve, industries, markets and LNG production capabilities.

    The ownership structure of Finland's leading natural gas company, Gasum, changed fundamentally in 1999, and the company is now no longer a subsidiary of Fortum Corporation. 'Our new strong and broad ownership base will enable us to develop the natural gas business and pipeline network in Finland in response to the requirements of our Finnish customers', says Antero Jaennes, Gasum's Chairman and CEO, who stresses that Gasum is committed to remaining the leading developer of the Finnish natural gas market and the number-one gas supplier. Natural gas usage in Finland in 1999 totalled 3.9 billion m 3 (38.7 TWh), unchanged from 1998. Natural gas accounted for 11% of Finland's total primary energy need, as it did in 1998. The proportion of natural gas used in district heating rose by 2% to 36%, and moved down 2% in power generation to 10%. Industry's use of natural gas fell 1% to 17%. 75% of natural gas was used in combined heat and power (CHP) generation in industry and district heating. In 2000, Gasum expects to sell 4 billion m 3 of natural gas (40 TWh)

    It is concluded that it is impossible at this time to forecast the volume of natural gas dissolved in water that can be economically recovered. The investigation to southern Louisiana, both onshore and offshore was confined. Estimates of the dissolved methane content are based upon information on temperatures, pressures, sandstone thicknesses, sandstone porosities, salinity, and the solubility of methane. The salinity of waters encountered in wells was estimated from wireline logs, and in turn used to reduce the estimated content of dissolved gas. The reductions range from 51 to 61 percent of the solubility of methane in fresh water. The assessment does not include gas dissolved in water contained in shale beds. A series of maps display the information used in the computation. Methane solubility values were multiplied by porosity--feet values for each 1000-foot interval. The total dissolved methane in the resource base is estimated to be 6,143 trillion cubic feet (Tcf); assumptions on the effect of salinity reduce this to 3,264 Tcf. This figure does not include methane beneath the Texas coast. Very preliminary estimates of the recoverable proportion of dissolved gas in the highly ''geopressured'' zones range from 1 to over 20 percent. Not all of the resource base estimates of 3,264 Tcf occurs in the highly geopressured zone, and the proportions individually allocatable within the resource base to the highly ''geopressured'' zone, to the intermediate-pressure zone, and to the normal or ''hydropressure'' zone cannotbe estimated readily. The environmental aspects of recovery of dissolved gas are also presented. The review is necessarily generalized, since it could not be based on actual experience. The problems include subsidence of land surface and possibly increased seismic activity. Fluid withdrawal might result in subsidence of the land surface, as well as activation of growth faults, with adjustments

    Using a set of unbalanced panel data for Chinese's cities during the period of 2006–2009, this study aims to estimate the price and income elasticities of residential demand for natural gas. Natural gas consumption is specified as a function of its own price; substitute prices; urban wages; and other supply, climate, and housing characteristics. Using a feasible generalised least squares (FGLS) technique, which controls for panel heteroskedasticity and panel correlation, we find that natural gas consumption is price elastic and income inelastic when other covariates (e.g., the supply of natural gas pipeline and heating degree days) are controlled. In addition, there are large variations in demand behaviours across China's regions. There is a substantial income effect on demand for natural gas in southern China, whereas the northern regions are found to have a higher price effect. In addition, the substitution effect between coal and natural gas is significant in North China but is not significant in South China. These findings have several important policy implications for natural gas pricing and supply cost analysis in the context of China. - Highlights: • We estimate the price and income elasticities of residential demand for natural gas. • We use a set of unbalanced panel data for Chinese's cities during 2006–2009. • We use a feasible generalised least squares approach. • We find that natural gas consumption is price elastic and income inelastic. • We find large variations in demand behaviours across China's regions

    The United States relies on natural gas for one-quarter of its energy needs. In 2001 alone, the nation consumed 21.5 trillion cubic feet of natural gas. A large portion of natural gas pipeline capacity within the United States is directed from major production areas in Texas and Louisiana, Wyoming, and other states to markets in the western, eastern, and midwestern regions of the country. In the past 10 years, increasing levels of gas from Canada have also been brought into these markets (EIA 2007). The United States has several major natural gas production basins and an extensive natural gas pipeline network, with almost 95% of U.S. natural gas imports coming from Canada. At present, the gas pipeline infrastructure is more developed between Canada and the United States than between Mexico and the United States. Gas flows from Canada to the United States through several major pipelines feeding U.S. markets in the Midwest, Northeast, Pacific Northwest, and California. Some key examples are the Alliance Pipeline, the Northern Border Pipeline, the Maritimes & Northeast Pipeline, the TransCanada Pipeline System, and Westcoast Energy pipelines. Major connections join Texas and northeastern Mexico, with additional connections to Arizona and between California and Baja California, Mexico (INGAA 2007). Of the natural gas consumed in the United States, 85% is produced domestically. Figure 1.1-1 shows the complex North American natural gas network. The pipeline transmission system--the 'interstate highway' for natural gas--consists of 180,000 miles of high-strength steel pipe varying in diameter, normally between 30 and 36 inches in diameter. The primary function of the transmission pipeline company is to move huge amounts of natural gas thousands of miles from producing regions to local natural gas utility delivery points. These delivery points, called 'city gate stations', are usually owned by distribution companies, although some are owned by

    This paper analyzes the residential natural gas demand per capita in 12 European countries using a dynamic log linear demand model, which allows for country-specific elasticity estimates in the short- and long-run. The explanatory variables included lagged demand per capita, heating degree days index, real prices of natural gas, light fuel oil, electricity, and real private income per capita. The short-run own-price and income elasticity tend to be very inelastic, but with greater long-run responsiveness. By splitting the data set in two time periods, an increase in the own-price elasticities were detected for the European residential natural gas demand market as a whole. We have provided support for employing a heterogeneous estimator such as the shrinkage estimator. But the empirical results also motivate a further scrutiny of its properties. (Author)

    Our econometric evidence indicates that changes in natural gas prices are unequal in the long run. Nonetheless, all downstream prices change by at least as much as the average well-head price. Statistically, residential and commercial prices change as much as the city gate price. In the face of persistent shocks, however, market institutions and market dynamics can lead to lengthy periods in which the residential and commercial prices of natural gas adjust less than the wellhead or city gate prices. Electrical and industrial users of natural gas rely heavily on spot supplies and can switch fuels easily. Their ability to switch fuels may be related to the development of a spot market to serve them. Reliance on the spot market may explain why these end users have seen a greater reduction in natural gas prices than have the LDCs over the past seven years. The ability to switch fuels may account for electrical and industrial prices being the source of shocks in their relationships with the wellhead price. It also may explain why prices in these end-sue markets are quick to adjust. Commercial and residential customers cannot switch fuels easily and rely heavily on LDCs for their natural gas. The inability of these end users to switch fuels probably contributes to the reluctance of LDCs to purchase spot supplies of gas. Reliance on contract supplies may explain why the city gate price has not declined as much as electrical and industrial prices of natural gas over the past seven years. Furthermore, the LDCs administer prices in the commercial and residential markets under state regulation

    Spokesmen for gas and electric utilities describe the relative merits of using natural gas and electric heat pumps. Both argue that their product is more economical and operates more efficiently than its competitor. Rising natural gas prices are responsible for making costs more competitive, although rates for both gas and electricity vary by region. The utilities also describe heat pump advantages in terms of installation ease and cost, reliability, maintenance, and thermal comfort. Both provide documentation to support their claims. 2 tables.

    2003-11-01

    This annual working paper was prepared to provide summaries of North American natural gas industry trends. It also reviews Canadian gas exports. It should be noted that the Mexican market was largely excluded from this report. The objective is to foster dialogue between government and industry to obtain feedback concerning natural gas issues. In the main section of the report, graphs were provided along with limited text comments, proposing a structured look at market fundamentals (supply and demand) over 2002, for the near term (2003 and early 2004), as well as the long term to 2015. Private consultants, industry associations, and federal government agencies in both Canada and the United States provided information that was used for preparing this report. A very mild 2001/2002 winter resulted in low demand for natural gas in the beginning of 2002. The market seemed to recognize that natural gas wells in North America were flowing at essentially full capacity. The core markets included residential and commercial demand. Storage levels and the weather are the two factors most likely to drive natural gas prices through the end of the winter of 2003/2004. Natural gas production growth and world crude oil prices are also expected to play an important role. On April 1, 2003, storage levels in North America were low, and industry was back on track by September 1, 2003 due to injections into storage during the summer. Natural gas demand in North America is expected to increase in the long term, fuelled by increased demand by industrial and electric power generation. North American production forecasts were revised downwards, compared to last year's report. The Canadian supply forecasts did not include Canadian imports of liquid natural gas or Newfoundland natural gas production. 25 refs., 16 tabs., 55 figs

    In 2010, natural gas provided 54% of total residential space heating energy the U.S. on a source basis, or 3.5 Quadrillion Btu. Natural gas burned in furnaces accounted for 92% of that total, and boilers and other equipment made up the remainder. A better understanding of installed furnace performance is a key to energy savings for this significant energy usage. Natural gas furnace performance can be measured in many ways. The annual fuel utilization efficiency (AFUE) rating provides a fixed value under specified conditions, akin to the EPA miles per gallon rating for new vehicles. The AFUE rating is provided by the manufacturer to the consumer and is a way to choose between models tested on the same basis. This value is commonly used in energy modeling calculations. ASHRAE 103 is a consensus furnace testing standard developed by the engineering community. The procedure provided in the standard covers heat-up, cool down, condensate heat loss, and steady-state conditions and an imposed oversize factor. The procedure can be used to evaluate furnace performance with specified conditions or with some variation chosen by the tester. In this report the ASHRAE 103 test result will be referred to as Annualized Efficiency (AE) to avoid confusion, and any non-standard test conditions will be noted. Aside from these two laboratory tests, steady state or flue loss efficiency can be measured in the field under many conditions; typically as found or tuned to the manufacturers recommended settings. In this report, AE and steady-state efficiency will be used as measures of furnace performance.

    The crisis has attracted the world`s attention on the need for energy conservation and the development in a greater extent the utilization of carbon base fuels and other energy sources (nuclear energy). Being a blast furnace, not only an energy consumer but also an energy producer, the greatest contribution to the pig iron cost is the energy needed to melt and reduce to metallic state the iron ores, this energy is mainly derived from coke. The dependence on coal via the coking plant to produce first fusion iron is incremented day after day as a result of the high levels of production. Altos Hornos de Mexico (AHMSA), contemplated within its strategic plan, the reduction in the production of its coking plants derived from the natural aging of its furnaces, consequently the shortage of coke for productions higher than 2.6 MMT of pig iron is pending. The injection of fuels into a blast furnace through its nozzles is a technology used for the diminishing the coke consumption of coke, its use implies a change in the philosophy of the blast furnace operation, and is currently employed in most of the blast furnaces of the world. AHMSA taking advantage of coal tar production (approx. 130 tons/day) in its coking plants decided the design and put into operation a co-injection system of coal tar and natural gas. The activities tending to carry out this project were initiated on April 1993, performing all of them with its own resources, completing them on July 18, 1993, day on which the injection of coal tar/natural gas in blast furnace No. 4 in a stable form. To date (October 1993), the coal tar injection has been increased up to 36 kg/ton of pig iron. During the injection periods, the presence of operational, mechanical and instrumentation problems have not been an obstacle for the evolution on the injection, fulfilling its function of substituting coke in a replacing relationship of 1:1, i.e. 1 kg of coal tar per each kg of coke, without affecting the product quality

    Natural gas theft causes major losses in the energy industry in Hungary. Among the non-technical losses occurring in natural gas networks, fraudulent residential consumption is one of the main factors. Up to 2014, gas meters that are most widely used in residential monitoring are manufactured with ferromagnetic moving components, which makes it possible to alter or disrupt the operation of the meters non-intrusively by placing permanent magnets on the casing of the meters. Magnetic remanence mapping was used to investigate a sample of 80 recalled residential meters and detect potentially fraudulent activity. 10% of the meters were found suspect by magnetic remanence measurement, of which 50% were confirmed to be potentially hijacked by further mechanical investigation. The details of the technique are described in this paper, along with experimental results and the discussion of the analysis of the real-world samples. Copyright © 2014 Elsevier Ireland Ltd.

    1995-01-01

    Natural gas could be an important alternative energy source in meeting some of the market demand presently met by liquid products from crude oil. This study was initiated to analyze three energy markets to determine if greater use could be made of natural gas or natural gas derived products and if those products could be provided on an economically competitive basis. The three markets targeted for possible increases in gas use were motor fuels, power generation, and the chemical feedstocks market. The economics of processes to convert natural gas to transportation fuels, chemical products, and power were analyzed. The economic analysis was accomplished by drawing on a variety of detailed economic studies, updating them and bringing the results to a common basis. The processes analyzed included production of methanol, MTBE, higher alcohols, gasoline, CNG, and LNG for the transportation market. Production and use of methanol and ammonia in the chemical feedstock market and use of natural gas for power generation were also assessed. Use of both high and low quality gas as a process feed stream was evaluated. The analysis also explored the impact of various gas price growth rates and process facility locations, including remote gas areas. In assessing the transportation fuels market the analysis examined production and use of both conventional and new alternative motor fuels

    Two main development could gradually modify these traditional features of natural gas markets and prices. First, environmental pressures and the tightening of emission standards and of the quality specifications for fuels should work in favor of natural gas. Second the increasing distance of resources in relation to the major consuming zones should bring about a considerable development of international natural gas trade. International expansion should mark the development of the gas industry in the coming decades. This evolution will give natural gas an importance and a role appreciably closer to those of oil on the world energy scene. But it is obvious that such a development can come about only at the cost of considerable investments for which the economic viability is and will remain dependent on the level of the prices of natural gas as the inlet to its consuming markets. This paper attempts to answer the questions: Will these markets accept a new scale of value for gas in relation to other fossil fuels, including oil, which will take into account new environmental constraints and which will be able to fulfill the formidable financial needs of the gas industry in the coming decades?

    An overview of the Bulgarian natural gas industry is presented. The starting point was the discovery of the indigenous Chiren gas-field in 1967. The first agreement with the ex-USSR for supply of natural gas and construction of main pipelines was signed in 1968. The state gas company BULGARGAZ is responsible for transportation, storage, distribution, processing and marketing of the gas to over 150 industrial companies in the country, as well as for the transportation services to gas importers in neighboring Turkey. The GAZSTROJMONTAZH company accomplish the construction of the local and transit pipelines to Turkey and Greece, as well as of some objects in Iran, Syria, Ukraine and Germany. In the past 20 years, 87890 million m 3 natural gas from Russia are supplied and 846 million m 3 - from domestic sources. The share of natural gas in the overall energy balance is 13.6% for 1992. The restructuring and further development of gas industry require to take into account some factors as: security in supply; investments for technical assurance; pricing policy for natural gas; development of private business. Some administrative problems are also mentioned. 2 tabs., 1 fig

    In 1987, Canada's National Energy Board (NEB) adopted a market-based procedure (MBP) to assess long-term gas exports. The MPB included monitoring and assessment of Maritimes natural gas markets. The NEB is responsible for interprovincial and international oil and gas pipelines as well as tolls and tariffs on NEB-regulated pipelines. The NEB is also responsible for electricity and natural gas exports and exploration programs on federally regulated lands not covered by an Accord agreement. The province of New Brunswick requested a new set of rules for the export of natural gas from the Maritimes to ensure competitiveness with other jurisdictions. The NEB decided that the public interest is best served by allowing the market to work. It also decided that the developing Maritimes market faces several challenges not faced by buyers in the export market. It was concluded that the market is working reasonably well to meet the needs of domestic consumers. 20 per cent of Scotian gas is being used in the Maritimes and many laterals have been constructed to extend service. Most major population centres have natural gas. However, there is no residential or commercial natural gas service in Nova Scotia, and only limited penetration of natural gas in residential and commercial markets in New Brunswick. Maritimers have a long history of using other fuel options and must make capital investment to switch to natural gas. They must, therefore, be convinced that investment will pay off in fuel savings and other benefits. The NEB will have to improve price transparency and strive for regulatory efficiency and cooperation with other jurisdictions. 2 figs

    A sectoral analysis of current trends in the use of natural gas in Italy shows that this energy source, now estimated to be covering 23.7% of total Italian national energy requirements, is fulfilling its role as an environmentally compatible, low cost and readily available energy alternative well suited to alleviate Italy's worrisome over-dependence on foreign supplied oil and reduce the severity of the urban air pollution problem (it being a low nitrogen oxide and carbon dioxide emitting, non-sulfur containing fuel). This paper expands this theme by giving a complete panorama of the natural gas market in Italy, sector by sector, and by coupling projections on the expected increased use of this energy source (as mandated by the National Energy Plan) with estimates of consequent reductions in air pollution based on a comparative analysis of fuel oil versus natural gas combustion

    Driving on natural gas (CNG, Compressed Natural Gas) has been the talk of the industry for many years now. Although the benefits of natural gas as an engine fuel have become well-known, this phenomenon does not seem to gain momentum in the Netherlands. Over the last few months, however, the attitude towards CNG seems to be changing. Energy companies are increasingly engaged in commercial activities, e.g. selling natural gas at petrol stations, an increasing number of car manufacturers are delivering natural gas vehicles ex-works, and recently the NGV (Natural Gas Vehicles) Holland platform was set up for the unequivocal marketing of natural gas as an engine fuel

    A technology characterization for liquefied natural gas (LNG) was made. The scope of work was confined to a literature review of LNG processes including natural gas production, liquefaction, and revaporization. The work was divided into five major categories as follows: (1) status of LNG projects, (2) general process description, (3) environmental aspects, (4) safety, and (5) economics. Each of these categories forms a major heading for this report. In addition, an LNG reference system of 250 million standard cubic feet per day (MMSCFD) is included in the report at Argonne National Laboratory's (Argonne) request. Information concerning this system was derived from other LNG systems in the literature. The report does not include an assessment of the market potential for the product gas or its end use. Published cost estimates in the literature have been identified but the original cost estimates have not been provided. Plant layouts, conceptual designs, and socioeconomic analysis are not provided.

    The geopolitical events over the last two years are such that the present natural gas supply schemes risk being overthrown. Recourse, to satisfy future European demands, to additional volumes coming from outlying sources will inevitably force the actors to define new strategies and to reconsider the reorganization of the transmission system' structure. Besides, the use of their capacities is closely bound to supply flexibility. At the same time, the saturation of the production and transmission capacities within the nearby outkirts combined with the purchasers' resolve to diversify their supply sources will undoubtedly shift the dynamics of the natural gas supply to potential sources and their access costs before the end of the century. 24 refs., 6 figs., 9 tabs., 4 maps

    Using the multi-cyclic Hubert approach, a 53 country-specific gas supply model was developed which enables production forecasts for virtually all of the world's gas. Supply models for some organizations such as OPEC, non-OPEC and OECD were also developed and analyzed. Results of the modeling study indicate that the world's supply of natural gas will peak in 2014, followed by an annual decline at the rate of one per cent per year. North American gas production is reported to be currently at its peak with 29 Tcf/yr; Western Europe will reach its peak supply in 2002 with 12 Tcf. According to this forecast the main sources of natural gas supply in the future will be the countries of the former Soviet Union and the Middle East. Between them, they possess about 62 per cent of the world's ultimate recoverable natural gas (4,880 Tcf). It should be noted that these estimates do not include unconventional gas resulting from tight gas reservoirs, coalbed methane, gas shales and gas hydrates. These unconventional sources will undoubtedly play an important role in the gas supply in countries such as the United States and Canada. 18 refs., 2 tabs., 18 figs

    The report focuses on the pricing of natural gas. The motivation has been the wish of the Norwegian authorities to increase the use of natural gas and that this should follow market conditions. The pricing of gas occurs at present in various ways in the different markets. The report identifies to main factors behind the pricing. 1) The type of market i.e. how far the liberalization of the gas markets has gone in the various countries. 2) The development within the regulation, climate and tax policies. The gas markets are undergoing as the energy markets in general, a liberalization process where the traditional monopoly based market structures are replaced by markets based on competition. There are great differences in the liberalization development of the various countries, which is reflected in the various pricing principles applied for the trade of gas in the countries. The analysis shows that the net-back-pricing is predominant in some countries i.e. that the price is in various ways indexed towards and follow the development of the price of alternative energy carriers so that the gas may be able to compete. The development towards trade places for gas where the pricing is based on offer and demand is already underway. As the liberalization of the European gas markets progresses it is expected that the gas price will be determined increasingly at spot markets instead of through bilateral agreements between monopolistic corporations. The development within the regulation, climate and tax policies and to what extent this may influence the gas prices in the future, are also studied. There seem to be effects that may pull in both directions but it is evident that these political variables will influence the gas pricing in the international market to a large extent and thereby also the future internal natural gas market

    In recent years, important structural and institutional transformations are observed, for consequence the questions on the energy industries had started to incorporate, the regulation problems. Thus, the simple creation of new regulating agencies does not assure the automatic fulfilment of the functions of public interest. In this new context, these tasks are much more complex, demanding a learning process: how much to the structures of market and how much to the strategical behavior of the companies. In the local scene, to consolidate the distribution of the natural gas for the residential segment is one of the challenges of the Bahiagas, mainly after the publication of the Resolution that will go to establish the General Conditions of Gas Supply Canalized in the Residential Classroom in the State of the Bahia (hearing publishes carried through N. 002/2006 in June/2006). In this context, it is important to deeply understand the Resolution, that consequently will go to print a new dynamics for the Bahiagas. (author)

    An increasing amount of natural gas is flowing into continental Europe, one of the largest gas markets in the world. There are three main sources of gas: Africa, Russia and Norway. Norway is an important supplier of gas, but may be vulnerable to competition. The demand for gas is increasing on a global basis and the largest increase is expected in Asia, followed by America and Europe. It is expected that Norwegian gas deliveries will be a principle source of natural gas for North Europe in the next years and that they will take an increasing part of the British market as the gas deliveries from the British shelf is going down. The European gas market is likely to become liberalized according to the EU's competition- and gas directives. This will not necessarily be a problem, and Norway may be able to increase the export of gas to Great Britain considerably from the year 2010, perhaps up to 40 billion standard m3 per year. Russia is expected to take an increased share of the European gas market, especially in East- and Central Europe, Germany and North Italy. But large investments in existing fields, new developments and new strategic pipelines are necessary

    This power point presentation addressed the following topics regarding development of natural gas in eastern Canada: (1) the 18 Tcf of proven natural gas reserves at Sable Island, (2) Canadian markets benefiting from the Maritimes and Northeast Pipeline (M and NP), (3) a 20 year franchise agreement between Enbridge Gas and the government of New Brunswick, (4) the 25 year provincial franchise agreement by Sempra Atlantic Gas, and (5) Sable Island's influence on central Canada. The Sable Offshore Energy Project (SOEP) is now producing about 540,000 MMBtu/day from 6 fields. Plans for Tier 2 expansion are underway. Firm contracts for the M and NP are scheduled to transport gas from the SOEP to markets in Nova Scotia, New Brunswick, Maine and New Hampshire. Sable gas is also a potential supply for the Quebec market. Gaz Metropolitain and Enbridge have proposed to build the Cartier Pipeline from the Quebec/New Brunswick border to Quebec City. It is unlikely that Sable Island supply will directly serve the Ontario market. Canadian customers for Sable gas and M and NP service include pulp and paper companies, oil refineries, power generators and local distribution companies (LDC), with the majority of demand coming form the electric power industry. tabs., figs

    A wide range of climate plans rely on energy efficiency to generate energy and carbon emissions reductions, but conventional wisdom holds that consumers have historically underinvested in energy efficiency upgrades. This underinvestment may occur for a variety of reasons, one of which is that consumers are not adequately informed about the benefits to energy efficiency. To address this, the U.S. Department of Energy created a tool called the Home Energy Score (HEScore) to act as a simple, low-cost means to provide clear information about a home’s energy efficiency and motivate homeowners and homebuyers to invest in energy efficiency. The Department of Energy is in the process of conducting four evaluations assessing the impact of the Home Energy Score on residential energy efficiency investments and program participation. This paper describes one of these evaluations: a randomized controlled trial conducted in New Jersey in partnership with New Jersey Natural Gas. The evaluation randomly provides homeowners who have received an audit, either because they have recently replaced their furnace, boiler, and/or gas water heater with a high-efficiency model and participated in a free audit to access an incentive, or because they requested an independent audit3, between May 2014 and October 2015, with the Home Energy Score.

  15. Natural gas: redistributing the economic surplus

    1990-01-01

    The natural gas has a limited role in the Brazilian energy balance. This role in industrial countries and some developing countries is much more important. Historically this contrasting situation can be explained by the limited natural gas reserves Brazil used to have. Since the oil crisis however the Brazilian natural gas reserves increased substantially without a similar increase in the role of natural gas in the energy balance. The existing institutional arrangement generates a struggle for the economic rent generated by natural gas production and consumption that seems to be at the core of this question. Our paper estimates the economic rent generated by natural gas in Brazil and its distribution among producers and consumers: it points toward a new institutional arrangement that could arguably, generate a new role for the natural gas in the Brazilian energy balance.

    Baniriah, N.

    1991-01-01

    In this report the worldwide position of natural gas as an important energy of the coming decades and its modest current standing in the Swiss energy balance are highlighted. The relative role and importance of the principal fossil fuels in the energy supply, the average energy prices and taxes, particularly those of gas and fuel oil in the residential sector and the overall statistically related inter-fuel substitution in Switzerland are examined. The role of governments in energy supply in general and with gas utilization in particular is examined. The international trade in gas and its supply infrastructure are reviewed and the advantageous situation of Switzerland in Western Europe and the latter in the World, with respect to present and future gas supplies, are underlined. Considering the current level of gas consumption in Switzerland and its past and projected rates of market penetration, in comparison to other OECD countries, it would appear that Switzerland is not taking full advantage of the situation. The implicit message, even if diffidently conveyed, is intervention by prescription and by proscription. In the absence of such measures, and with the virtual demise of nuclear energy or its expansion, the disproportionate and dominant position of fuel oil in the energy mix, will endure whereas the share of gas grows very slowly remaining at much lower levels than in the neighbouring countries.

    1997-01-01

    Centra Gas B.C. Inc., a wholly owned subsidiary of Westcoast Energy Inc., delivers gas to 54,000 residential and commercial customers and seven large market pulp mills in British Columbia. Over the next few years, Centra Gas expects their throughput capacity to double from 100 million cubic feet of gas/day to about 200 million cubic feet/day. Currently, there is about 2,500 km of distribution mains in place and new mains are being added at the rate of 200 km/year. The distribution system includes 565 km of pipeline for Vancouver Island. The B.C. government has announced plans to build two cogeneration plants on the Island which will have major positive economic and environmental impacts. Consumer benefits include not only one of the cleanest, most reliable, efficient and versatile energy sources available today, but also significant reductions in particulate and carbon dioxide emissions, high efficiency and instant response of natural gas appliances, as well as stability for existing industry and jobs, and the opportunity to expand, or to attract new industry and additional employment

  19. Europe's future is natural gas

    Sponheuer, T.

    1992-01-01

    This paper reports that Western Europe, with its substantial intraregional gas exports and imports, and its imports from outside the region, is a hub of international gas trading. Steel pipelines with diameters to 56 in. have proven to be a technically appropriate, cost-efficient system for the large-scale transportation of natural gas. In 1990, 74% of the trade in international markets was moved through pipelines. Worldwide, more than 800,000 miles of high-pressure gas pipelines are in operation. Laid end to end, these lines would stretch 30 times around the equator. The future progress for pipeline construction in Europe depends on the development of gas demand and the avenues open to the European gas industry to meet this demand

    Weegink, R.J.; Abbing, H.W.

    1991-01-01

    The consumption of natural gas by Dutch households and underlying trends influencing the natural gas consumption are investigated annually by means of a survey involving more than 2,700 households. The small-scale consumption totals some 11,65 billion m 3 in 1991 of which 79% was used for space heating and 18% for hot water production. Data are presented on types of residential buildings, the penetration of several forms of thermal insulation, the penetration of cooking appliances, heating systems, and fireplaces per building type, and natural gas consumption for space heating, also per type of building. 7 figs., 14 tabs

    2011-01-01

    In this paper we consider the problem of natural gas consumption hourly forecast on the basis of hourly movement of temperature and natural gas consumption in the preceding period. There are various methods and approaches for solving this problem in the literature. Some mathematical models with linear and nonlinear model functions relating to natural gas consumption forecast with the past natural gas consumption data, temperature data and temperature forecast data are mentioned. The methods are tested on concrete examples referring to temperature and natural gas consumption for the area of the city of Osijek (Croatia) from the beginning of the year 2008. The results show that most acceptable forecast is provided by mathematical models in which natural gas consumption and temperature are related explicitly.

    Nogami, T.; Oya, N.; Ishida, H.; Matsumoto, H.

    2008-01-01

    Recent studies in Japan have suggested that natural gas hydrate (NGH) transportation of natural gas is more economical than liquefied natural gas (LNG) transportation systems for small, medium and remote gas fields. Researchers in Japan have built a 600 kg per day NGH production and pelletizing plant and regasification facility. This paper discussed feasibility studies conducted in southeast Asia to determine the unit's commercialization potential with large natural gas-related businesses including shipping companies and electric power utilities. The total supply chain was compared with the corresponding liquefied natural gas (LNG) and compressed natural gas (CNG) supply chains. The study also examined natural gas reserves, energy policies, the positioning of natural gas supplies, and future forecasts of natural gas demand. A conceptual design for an NGH supply chain in Indonesia was presented. Results of the study have demonstrated that the NGH chain is an appropriate and economically feasible transportation method for many areas in southeast Asia. 8 refs., 10 figs

    Issues regarding future natural gas prices for North America were discussed. Various aspects of the issue including the relationship between storage, weather and prices, received attention. It was noted that strong demand-growth will be needed to support near-term Canadian export increases without price declines. The issue of Gulf Coast production was also discussed. Power generation using natural gas as fuel is expected to support strong growth in the demand for natural gas. tabs., figs

  5. New opportunities for natural gas

    International Nuclear Information System (INIS)

    Newcomb, J.

    1991-01-01

    This paper reports that the prospect of extremely low gas prices - approaching $1.00 per million Btu (MMBtu) on a seasonal basis - is frightening many producers. The presence of large gas inventories only serves to intensify these fears. Threats of declining market conditions stir the question: How should producers react to these prices? On the score, the experts advise: One of the first rules of playing the power game is that all bad news must be accepted calmly as if one already knew and didn't much care. Although stated jokingly, there is a kernel of truth to the suggestion. Having thought through the adversities involved in the worst case scenario - and for natural gas producers and other industry participants, those adversities are formidable - companies may be better prepared to adapt to the worst case, should it happen to materialize. Here, the bad news is that CERA foresees serious near-term perils that could route the industry toward that worst case. The good news is that long-term prospects provide a cause for optimism

  6. Canadian natural gas price forecast

    Jones, D.

    1998-01-01

    The basic factors that influenced NYMEX gas prices during the winter of 1997/1998 - warm temperatures, low fuel prices, new production in the Gulf of Mexico, and the fact that forecasters had predicted a mild spring due to El Nino - were reviewed. However, it was noted that for the last 18 months the basic factors had less of an impact on market direction because of an increase in Fund and technical trader participation. Overall, gas prices were strong through most of the year. For the winter of 1998-1999 the prediction was that NYMEX gas prices will remain below $2.00 through to the end of October 1998 because of high U.S. storage levels and moderate temperatures. NYMEX gas prices are expected to peak in January 1999 at $3.25. AECO natural gas prices were predicted to decrease in the short term because of increasing levels of Canadian storage, and because of delays in Northern Border pipeline expansions. It was also predicted that AECO prices will peak in January 1999 and will remain relatively strong through the summer of 1999. tabs., figs

  7. The economics of natural gas

    1990-01-01

    Natural gas resembles oil in fulfilling a wide variety of uses as both a source of energy and a feedstock, but the proportion of world production that is traded internationally is very much lower, and insufficient for a world price of gas to be established. Written specifically for economists interested in energy, development and industrial economics; oil and gas industry personnel; officials of developing countries; and intergovernmental organizations concerned with development. This book addresses the issues of how the economic price of gas is determined within individual countries with different characteristics and which factors should be taken into account by governments in the formulation of pricing policies that are appropriate for gas. These are illustrated with estimates of the costs of exploration and production of gas, and of the benefits to be derived from its use in various economic sectors for a number of Third World countries. The book also presents a detailed case study of the development of gas pricing in Bangladesh, and an analytical framework for the development of a formal gas planning model that could be applied to the cases of actual countries contemplating the development of gas use in the future

  8. Will southern California remain a premium market for natural gas?

    International Nuclear Information System (INIS)

    John, F.E.

    1991-01-01

    Average yearly demand for natural gas in southern California totalled just over 3 billion ft 3 /d in 1991 and is projected to increase to just over 3.2 billion ft 3 /d in 2000 and 3.4 billion ft 3 /d in 2010. In the core residential market, demand is being driven by population growth and offset by conservation measures. In the core commercial and industrial market, demand is driven by employment growth and offset by conservation. In the noncore market, natural gas use is expected to fall from 262 million ft 3 /d in 1991 to 223 million ft 3 /d in 2010. Demand for natural gas for cogeneration is expected to either remain stagnant or decrease. The largest potential for market growth in southern California is for utility electric generation. Demand in this sector is expected to increase from 468 million ft 3 /d in 1991 to 1 billion ft 3 in 2010. Air quality concerns furnish a market opportunity for natural gas vehicles, and a substantial increase in natural gas demand might be obtained from even a modest market share of the region's 10 million vehicles. Existing pipeline capacity is sufficient to supply current average year requirements, and the need for new capacity hinges on the issues of satisfying high-year demand, meeting market growth, and accessing more desirable supply regions. Planned capacity additions of 2,150 million ft 3 /d, if completed, will bring substantial excess capacity to southern California in the late 1990s. The competitive advantages of various producing regions will then be greatly influenced by the rate designs used on the pipelines connecting them to the market. 4 tabs

    This paper tables numerous statistical data to evidence that whereas the use of natural gas as an automotive fuel for private and public vehicles is growing in Asia, North and South America, in Europe this trend is currently being followed only in Italy. However, with the relatively recent expansion of the European Communities' natural gas distribution network, coupled with growing interest in this fuel as a cost effective and environmentally compatible alternative to petroleum, the demand for natural gas automotive fuels is expected to increase even in this continent. The trucking industry in particular should derive significant benefits from the switch to natural gas

  11. Natural gas vehicles. An option for Europe

    International Nuclear Information System (INIS)

    Engerer, Hella; Horn, Manfred

    2010-01-01

    In Europe natural gas vehicles play a minor role. A decisive reason for this is the dependence of most European countries from gas imports. Except for Italy, there is no tradition to use natural gas as fuel. In addition, there is a lack of infrastructure (e.g. fuelling stations). In contrast to Europe, in Latin American and Asian countries natural gas vehicles are widespread. Some countries foster natural gas vehicles because they have own gas resources. Many countries must reduce the high air pollution in big cities. Environmental reasons are the main motive for the use of natural gas vehicles in Europe. In last years, high oil prices stimulated the use of natural gas as fuel. European governments have developed incentives (e.g. tax reductions) to foster natural gas vehicles. However, the focus is on hybrid technology and the electric car, which, however, need further technical improvement. In contrast, the use of natural gas in conventional engines is technically mature. Additional gas imports can be avoided by further improvements of energy efficiency and the use of renewable energy. In sum, the market penetration of natural gas as fuel should be promoted in Europe.

    Natural gas hydrate (NGH) is a viable alternative to LNG (Liquefied Natural Gas) or pipelines for the transportation of natural gas from source to demand. It involves three stages: production, transportation and re-gasification. The production of the hydrate occurs at pressures >50 bar at temperatures ~10oC in the presence of water and natural gas (particularly methane, ethane, propane). Transportation is by insulated bulk carrier at around –5 oC and atmospheric pressure or 0 oC at 10 bar, an...

  13. Evaluation And Analysis of Natural Gas Rates

    Taheri, Ali Akbar

    1999-01-01

    Natural gas is considered as a preferred fuel and its utility is growing every day in the country (Iran). The usage of natural gas has increased from 3.5 to 44 billion cubic meters from 1980 to 1997, respectively. Currently, 4 million residences and most of the industrial sector are being provided with the pipelined natural gas. Because of the tremendous increase in consumption, it is necessary to give the needed considerations to natural gas rate structure. The objective of the paper is to 1.Evaluate the fundamentals and principal methods used for rate structures. 2. Identification of effective components. 3. Analyze the current rates including connection fees and other customer charges

  16. Effect of Energy Efficiency Standards on Natural Gas Prices

    Energy Technology Data Exchange (ETDEWEB)

    Carnall, Michael; Dale, Larry; Lekov, Alex

    2011-07-26

    A primary justification for the establishment of energy efficiency standards for home appliances is the existence of information deficiencies and externalities in the market for appliances. For example, when a long-term homeowner purchases a new gas-fired water heater, she will maximize the value of her purchase by comparing the life-cycle cost of ownership of available units, including both total installed cost - purchase price plus installation costs - and operating cost in the calculus. Choice of the appliance with the lowest life-cycle costs leads to the most economically efficient balance between capital cost and fuel cost. However, if the purchaser's expected period of ownership is shorter than the useful life of the appliance, or the purchaser does not pay for the fuel used by the appliance, as is often the case with rental property, fuel cost will be external to her costs, biasing her decision toward spending less on fuel efficiency and resulting in the purchase of an appliance with greater than optimal fuel usage. By imposing an efficiency standard on appliances, less efficient appliances are made unavailable, precluding less efficient purchases and reducing fuel usage. The reduction in fuel demanded by residential users affects the total demand for such fuels as natural gas, for example. Reduced demand implies that residential customers are willing to purchase less gas at each price level. That is, the demand curve, labeled D{sub 0} in Figure 1, shifts to the left to D{sub 1}. If there is no change in the supply function, the supply curve will intersect the demand curve at a lower price. Residential demand is only one component of the total demand for natural gas. It is possible that total demand will decline very little if demand in other sectors increases substantially in response to a decline in the price. If demand does decrease, modeling studies generally confirm the intuition that reductions in demand for natural gas will result in reductions

    COOK,Z.

    1999-02-01

    The Seaport Liquid Natural Gas Study has attempted to evaluate the potential for using LNG in a variety of heavy-duty vehicle and equipment applications at the Ports of Los Angeles and Oakland. Specifically, this analysis has focused on the handling and transport of containerized cargo to, from and within these two facilities. In terms of containerized cargo throughput, Los Angeles and Oakland are the second and sixth busiest ports in the US, respectively, and together handle nearly 4.5 million TEUs per year. At present, the landside handling and transportation of containerized cargo is heavily dependent on diesel-powered, heavy-duty vehicles and equipment, the utilization of which contributes significantly to the overall emissions impact of port-related activities. Emissions from diesel units have been the subject of increasing scrutiny and regulatory action, particularly in California. In the past two years alone, particulate matter from diesel exhaust has been listed as a toxic air contaminant by CAM, and major lawsuits have been filed against several of California's largest supermarket chains, alleging violation of Proposition 65 statutes in connection with diesel emissions from their distribution facilities. CARE3 has also indicated that it may take further regulatory action relating to the TAC listing. In spite of these developments and the very large diesel emissions associated with port operations, there has been little AFV penetration in these applications. Nearly all port operators interviewed by CALSTART expressed an awareness of the issues surrounding diesel use; however, none appeared to be taking proactive steps to address them. Furthermore, while a less controversial issue than emissions, the dominance of diesel fuel use in heavy-duty vehicles contributes to a continued reliance on imported fuels. The increasing concern regarding diesel use, and the concurrent lack of alternative fuel use and vigorous emissions reduction activity at the Ports

  1. Adams natural gas/diesel demonstration project

    Energy Technology Data Exchange (ETDEWEB)

    1990-06-01

    The results of a ore-year program to demonstrate the viability of fuelling and operating diesel road vehicles on dual fuel natural gas/diesel under commercial operating conditions is presented. During this project a natural gas fuelling station designed to accomodate the specific needs of heavy trucks was constructed, and a Canada Safeway Ltd. tractor was converted to dual fuel natural gas/diesel operation. The truck accumulated more than 64,000 km during the one-year monitoring period, providing useful data in terms of comparative fuel efficiency, natural gas/diesel proportions of fuel use, operating range, and refuelling times, along with assessments of its performance by drivers and fleet management. In the dual fuel mode the truck experienced a 15% loss in thermal efficiency relative to straight diesel fuel during highway operation, and a 20% loss during local operation. Fuel cost savings resulting from the use of natural gas were not large given the increased level of fuel consumption and the purchase of natural gas at higher prices. If the fleet were to have its own natural gas fuelling station fuel cost savings would be substantially increased. Areas in which further development is needed for natural gas to emerge as a significant fuel for heavy trucks are mentioned. 3 figs., 15 tabs.

    The core of this article is a critical analysis of different forms of pricing of natural gas existing in the world today. This paper is to describe the various scenarios of natural gas price formation models. Along the paper, the context is emphasized by considering their cases of applications and their results. Today, basically, there are three main groups of models for natural gas pricing: i) competition gas-on-gas, i.e., a liberalized natural gas market, II) gas indexed to oil prices or its products and III) bilateral monopolies and regulated prices. All the three groups of models have relevant application worldwide. Moreover, those are under dynamic influence of economic, technological and sociopolitical factors which bring complexity to the many existing scenarios. However, at first this paper builds a critical analysis of the international current situation of natural gas today and its economic relevance. (author)

    The paper discusses the natural gas market and environmental needs with topics as follow: Importance of the North Sea region; sustainable development on the balance between economic use and environmental protection; role of natural gas in meeting energy demand: market needs, technologies, environmental aspects. According to the author, natural gas causes minimal pollutants because it contains virtually no pollutant-forming substances such as heavy metals, sulphur, chlorine or fluorine. No solid residues exist in the combustion space such as ash, slag, dust or soot, and the formation of thermal NO x through natural gas combustion has decreased to a very large extent as a result of technical advances. Natural gas can make a significant contribution towards reducing CO 2 emissions due to its very high hydrogen content. 12 figs

    Korea s natural gas demand has increase enormously since 1986. Natural gas demand in Korea will approach to 29 million tonnes by the year 2010, from little over 9 million tonnes in 1996. This rapid expansion of natural gas demand is largely due to regulations for environmental protection by the government as well as consumers preference to natural gas over other sources of energy. Especially industrial use of gas will expand faster than other use of gas, although it will not be as high as that in European and North America countries. To meet the enormous increase in demand, Korean government and Korea Gas Corporation (KOGAS) are undertaking expansion of capacities of natural gas supply facilities, and are seeking diversification of import sources, including participation in major gas projects, to secure the import sources on more reliable grounds.

    A new study of the Australian natural gas industry by leading Australian economics and policy consultancy ACIL Tasman highlights the significant supply and demand side uncertainties currently facing the industry. The ACIL Tasman 'Australian Gas Market Review and Outlook 2004' study presents modelling results for three supply/demand scenarios in Eastern Australia and two in Western Australia. The results show that, even under moderate assumptions about future levels of gas demand growth, major supply-side investment is likely to be needed over the next ten to fifteen years. The base supply/demand scenario for Eastern Australia and Northern Territory, illustrated in Figure 1, shows that even allowing for substantial new discoveries in existing production basins and major expansion of coal seam methane production, in the absence of a northern gas connection to the eastern states (Timor Sea or PNG Highlands) a significant supply gap will begin to emerge from around 2013. The study identifies several supply-side options for Eastern Australia - new discoveries in the established production provinces in Bass Strait and Central Australia; greenfield developments such as the Otway Basin offshore from Victoria and South Australia; continuing expansion of coal seam methane production in Queensland and New South Wales; and gas from Papua New Guinea, Timor Sea or from the North West Shelf region delivered via a trans-continental pipeline. The study concludes that it is unlikely that any single option will suffice to meet future demand. Almost inevitably, a combination of these sources will be needed if anticipated growth opportunities are to be met. With regard to prices, the study shows that in the short to medium term the outlook is for some real reductions in wholesale prices in most regional markets. This reflects increasing levels of upstream competition and declining real costs of pipeline transportation. However in the longer term, supply-side constraints will tend to

  16. Natural gas market review 2006 - towards a global gas market

    2006-01-01

    Natural gas is essential to the world economy. Gas now accounts for almost a quarter of OECD primary energy requirements and is expected to become the second most important fuel in the world in the next decade. Industrial and residential consumers increasingly rely on natural gas to keep their houses warm, their lights on and their factories running. Meanwhile the gas industry itself has entered a new phase. Where gas used to be restricted to regional markets, it is now increasingly traded on a global scale. While gas production and transport requires long-term investment, now it is optimised on a short-term basis. Demand continues to grow, but local gas production has become much more expensive. How should we react? How will demand be satisfied? What changes are required to promote flexibility and trade? What are the implications for gas security, investment and interdependence? At stake is an opportunity to diversify supply and demand - but this goal is threatened by barriers to competition and investment. This book is the first of a new IEA publication series. It takes an unprecedented look at developments in natural gas to 2010, analysing not only the three IEA regions (Asia Pacific, North America and Europe) but also broader global trends, such as the interaction of pipeline gas with LNG which binds the regions together. The Review provides invaluable insights for understanding this dynamic market

    The transportation sector is responsible for more than 50% of all oil products consumed, and it is the fastest growing oil demand sector and the fastest growing source of emissions. During the last 10 years there have been a considerable and growing effort in developing internal combustion gas engines. This effort has resulted in gas engines with efficiencies comparable to the diesel engines and with emissions considerably lower than engines burning conventional fuels. This development offers us opportunities to use natural gas very efficiently also in the transportation sector, resulting in reduced emissions. However, to utilize all the built in abilities natural gas has as engine fuel, the natural gas composition must be kept within relatively narrow limits. This is the case with both diesel and gasoline today. A further development require therefore specified natural gas compositions, and the direct use of pipeline natural gas as today would only in limited areas be acceptable. An interesting possibility for producing a specified natural gas composition is by LNG (Liquid Natural Gas) production. (EG)

    Density functional theory was performed for thermodynamic predictions on natural gas, whose B3LYP/6-311++G(d,p), B3LYP/6-31+G(d), CBS-QB3, G3, and G4 methods were applied. Additionally, we carried out thermodynamic predictions using G3/G4 averaged. The calculations were performed for each major component of seven kinds of natural gas and to their respective air + natural gas mixtures at a thermal equilibrium between room temperature and the initial temperature of a combustion chamber during the injection stage. The following thermodynamic properties were obtained: internal energy, enthalpy, Gibbs free energy and entropy, which enabled us to investigate the thermal resistance of fuels. Also, we estimated an important parameter, namely, the specific heat ratio of each natural gas; this allowed us to compare the results with the empirical functions of these parameters, where the B3LYP/6-311++G(d,p) and G3/G4 methods showed better agreements. In addition, relevant information on the thermal and mechanic resistance of natural gases were investigated, as well as the standard thermodynamic properties for the combustion of natural gas. Thus, we show that density functional theory can be useful for predicting the thermodynamic properties of natural gas, enabling the production of more efficient compositions for the investigated fuels.

  20. Natural gas: an environmental-friendly solution?

    Since 1970, the portion of natural gas in energy consumption in Western-Europe has grown by 6 percent per year on the average. About 20 percent of the energy demand in Western-Europe is now covered by natural gas. It is forecasted that this growth will continue at a rate of 2 percent per year until 2010. The natural gas consumption will increase from 325 billion cubic metres in 1993 to 450 billion cubic metres per year in 2010. For the coming 10 to 15 years, the natural gas demand is covered by long-term contracts with gas producing countries. From 2010 on, additional contracts, covering 70 to 120 billion cubic metres per year are required. A shift in geographic distribution of countries from which natural gas will be imported by Western-European countries is expected, which implies high investments and additional costs for transport and distribution of natural gas. Due to its qualities with respect to environmental impact, yield, availability, and advanced technology, natural gas is the energy vector of the 21 first century. (A.S.)

    In the United States, recent shale gas discoveries have generated renewed interest in using natural gas as a vehicular fuel, primarily in fleet applications, while outside the United States, natural gas vehicle use has expanded significantly in the past decade. In this report for the U.S. Department of Energy's Clean Cities Program - a public-private partnership that advances the energy, economic, and environmental security of the U.S. by supporting local decisions that reduce petroleum use in the transportation sector - we have examined the state of natural gas vehicle technology, current market status, energy and environmental benefits, implications regarding advancements in European natural gas vehicle technologies, research and development efforts, and current market barriers and opportunities for greater market penetration. The authors contend that commercial intracity trucks are a prime area for advancement of this fuel. Therefore, we examined an aggressive future market penetration of natural gas heavy-duty vehicles that could be seen as a long-term goal. Under this scenario using Energy Information Administration projections and GREET life-cycle modeling of U.S. on-road heavy-duty use, natural gas vehicles would reduce petroleum consumption by approximately 1.2 million barrels of oil per day, while another 400,000 barrels of oil per day reduction could be achieved with significant use of natural gas off-road vehicles. This scenario would reduce daily oil consumption in the United States by about 8%.

    This report describes work performed during a thirty month project which involves the production of dimethyl ether (DME) on-site for use as an ignition-improving additive in a compression-ignition natural gas engine. A single cylinder spark ignition engine was converted to compression ignition operation. The engine was then fully instrumented with a cylinder pressure transducer, crank shaft position sensor, airflow meter, natural gas mass flow sensor, and an exhaust temperature sensor. Finally, the engine was interfaced with a control system for pilot injection of DME. The engine testing is currently in progress. In addition, a one-pass process to form DME from natural gas was simulated with chemical processing software. Natural gas is reformed to synthesis gas (a mixture of hydrogen and carbon monoxide), converted into methanol, and finally to DME in three steps. Of additional benefit to the internal combustion engine, the offgas from the pilot process can be mixed with the main natural gas charge and is expected to improve engine performance. Furthermore, a one-pass pilot facility was constructed to produce 3.7 liters/hour (0.98 gallons/hour) DME from methanol in order to characterize the effluent DME solution and determine suitability for engine use. Successful production of DME led to an economic estimate of completing a full natural gas-to-DME pilot process. Additional experimental work in constructing a synthesis gas to methanol reactor is in progress. The overall recommendation from this work is that natural gas to DME is not a suitable pathway to improved natural gas engine performance. The major reasons are difficulties in handling DME for pilot injection and the large capital costs associated with DME production from natural gas.

    The Danish natural gas network has been established during the past 10 years. Running parallel with this a small but growing production of biogas from centralized biogas plants and landfills has been developed. The annual biogas production is expected to keep growing and increase tenfold in the next 25 year period with a reduction of green house gas emissions as one of the important incentives. The last years' development and expansion of the Danish biogas sector has shown a need for combined utilization of biogas and natural gas. If larger volumes of biogas are present, upgrading and distribution by the natural gas network may be an alternative to combined utilization. (au) 12 refs

    The strategy of restricting natural gas to noble uses (directive of EEC and endorsed by the IEA) impeded gas expansion despite substantial upward revisions in the assessment of available resources. However, increasing environmental concern slowly but gradually undermines this strategy because natural gas serves as a substitute for costly abatement. This article discusses the prospect of future natural gas consumption considering economic and ecological facts as well as strategic and political considerations. In fact, we argue that inconsistent political interventions first seriously lowered gas penetration but now favor its use

    The underlying resource base for North America natural gas is large, sufficient for nearly 100 years of current consumption. As such, the issues are not the size of the resource, but how to convert this resource into economically competitive supply. The key questions are: Will the cost (price) of natural gas remain competitive? What is the status of near-term deliverability? Will there be enough supply to meet growing demand? These economic and market issues frame the outlook for gas supplies in North America. Most importantly, they will determine how natural gas emerges from its competition for markets with other fuels and electricity. The paper addresses these questions by examining: (1) the underlying nature of the natural gas resource base; (2) the current status and trends in deliverability; and, (3) the potential of new technologies for producing gas more cost-effectively.

    China's natural gas consumption is growing rapidly and it has being driven by economic growth, industrialization and urbanization. In addition, the country's low-carbon development strategy, government-controlled gas price, and some other factors also contribute to the surging gas consumption. This paper studies China's natural gas consumption in residential, industrial and commercial sectors. We adopt the cointegration test and error correction model to study the relationships of explanatory factors and gas consumption of different sectors and climate factor is included into the analysis. In order to find the direction of natural gas pricing reform and establish the benchmark gas price, this paper also estimates the size of gas price subsidy by using price-gap approach. Our findings are as follows: In the long term, China's residential sector is more sensitive to price than the other two. Urbanization is an important factor promoting industrial and commercial gas consumption. Prices of other energies have an influence on natural gas consumption significantly due to the substitutability between energies. The slow-moving and unsatisfying pricing reforms on refined oil and natural gas lead to positive price elasticity of natural gas in the commercial sector, which implies that a further energy price reform is still stringent for China. - Highlights: • We figured out the price elasticity of different sectors. • We figured out the income elasticity of different sectors. • We introduced temperature factor into the study of natural gas consumption. • We study the natural gas subsidy of different sectors

    This article explores the dynamics between natural gas supply and demand in Italy. In order to supply Italy with increasing volumes of gas, several new pipelines and re gasification plants are expected in the next future, but their implementation is uncertain. Thus, there exist the possibility of natural gas shortage in the future. On the other hand, if all the expected projects will be implemented, situations of oversupply cannot be excluded. A system dynamics model deepens such as issue [it

    The production of natural gas is strongly increasing around the world. Long-run negative external effects of extraction are understudied and often ignored in social) cost-benefit analyses. One important example is that natural gas extraction leads to soil subsidence and subsequent induced earthquakes that may occur only after a couple of decades. We show that induced earthquakes that are noticeable to residents generate substantial non-monetary economic effects, as measured by their effects o...

    2013-01-01

    This paper examines the relationship between natural gas consumption and economic growth in Iran within a multivariate production model. We also investigate the effects of natural gas price on its consumption and economic growth using a demand side model. The paper employs bounds test approach to level relationship over the period of 1972–007. We find evidence of bidirectional positive relationship between natural gas consumption and economic growth in short-run and long-run, based on the production model. The findings also suggest that real GDP growth and natural gas have positive and negative impacts on gross fixed capital formation, respectively. Employment, however, was found to have negative but insignificant impact on gross fixed capital formation. Moreover, the estimation results of demand side model suggest that natural gas price has negative and significant impact on natural gas consumption only in the long-run, though there is insignificant impact on economic growth. These results imply that the Iranian government's decision for natural gas price liberalization has the adverse effects on economic growth and policy makers should be cautious in doing this policy. - Highlights: • Iran has been considered as a major natural gas producer in the world. • This paper examines the relationship between gas consumption and growth in Iran. • Positive impact of gas consumption on growth has been obtained. • The paper finds that gas consumption and income reinforce each other in Iran. • Natural gas price has also negative and significant impact on natural gas consumption in Iran

  11. Carbothermal Reduction of Quartz with Carbon from Natural Gas

    Li, Fei; Tangstad, Merete

    2017-04-01

    Carbothermal reaction between quartz and two different carbons originating from natural gas were investigated in this paper. One of two carbons is the commercial carbon black produced from natural gas in a medium thermal production process. The other carbon is obtained from natural gas cracking at 1273 K (1000 °C) deposited directly on the quartz pellet. At the 1923 K (1650 °C) and CO atmosphere, the impact of carbon content, pellet structure, gas transfer, and heating rate are investigated in a thermo-gravimetric furnace. The reaction process can be divided into two steps: an initial SiC-producing step followed by a SiO-producing step. Higher carbon content and increased gas transfer improves the reaction rate of SiC-producing step, while the thicker carbon coating in carbon-deposited pellet hinders reaction rate. Better gas transfer of sample holder improves reaction rate but causes more SiO loss. Heating rate has almost no influence on reaction. Mass balance analysis shows that mole ratios between SiO2, free carbon, and SiC in the SiC-producing step and SiO-producing step in CO and Ar fit the reaction SiO2(s) + 3 C(s) = SiC(s) + 2 CO(g). SiC-particle and SiC-coating formation process in mixed pellet and carbon-deposited pellet are proposed. SiC whiskers formed in the voids of these two types of pellets.

    Energy forecasting requirements for Slovenia's natural gas market were investigated along with the cycles of natural gas consumption. This paper presented a short-term natural gas forecasting approach where the daily, weekly and yearly gas consumption were analyzed and the information obtained was incorporated into the forecasting model for hourly forecasting for the next day. The natural gas market depends on forecasting in order to optimize the leasing of storage capacities. As such, natural gas distribution companies have an economic incentive to accurately forecast their future gas consumption. The authors proposed a forecasting model with the following properties: two submodels for the winter and summer seasons; input variables including past consumption data, weather data, weather forecasts and basic cycle indexes; and, a hierarchical forecasting structure in which a daily model was used as the basis, with the hourly forecast obtained by modeling the relative daily profile. This proposed method was illustrated by a forecasting example for Slovenia's natural gas market. 11 refs., 11 figs

  13. Natural gas pricing reform in China: Getting closer to a market system?

    2015-01-01

    Recent policy in China targets an increase in the contribution of natural gas to the nation's energy supply. Historically, China's natural gas prices have been highly regulated with a goal to protect consumers. The old pricing regime failed to provide enough incentives for natural gas suppliers, which often resulted in natural gas shortage. A new gas pricing reform was tested in Guangdong and Guangxi provinces in 2011, and introduced nationwide in 2013. The reform is aimed at creating a more market-based pricing mechanism. We show that a substantial progress toward a better predictability and transparency of prices has been made. The prices are now more connected with the international fuel oil and liquid petroleum gas prices. The government's approach for a temporary two-tier pricing when some volumes are still traded at old prices reduced a potential opposition during the new regime implementation. Some limitations of the natural gas pricing remain as it created biased incentives for producers and favors large natural gas suppliers. The pricing reform at its current stage falls short of establishing a complete market mechanism driven by an interaction of supply and demand of natural gas in China. - Highlights: • China's reform of natural gas pricing is in effect nationwide from 2013. • Prices are now connected to international fuel oil and liquid petroleum gas prices. • The reform benefits domestic producers and importers of natural gas. • There are still price distortions between industrial and residential sector. • The reform needs to create a system where both supply and demand are considered.

    Natural gas is the cleanest fossil fuel, but never got the chance to develop its use. The reason for that is the notion that the natural gas supplies would last for only some decennia. That is only right for the conventional gas supplies. In ice crystals, some hundreds of meters deep in the oceans, enormous methane reserves, many times larger than the conventional supplies, are enclosed in so-called clathrates. From the literature it appears that other sources of natural gas or methane and new options to use these energy sources are considered or to be developed. Attention is paid to the methane reserves in geologic formations, methane produced by microbes, and methane in clathrates. It is estimated that the methane reserve is 8 x 10 2 3 Joule. By using natural gas as a fuel CO 2 emission will be reduced considerably. Methane emission however must be limited, because of the reducing effect of methane on the oxygen production in the troposphere. The large reserves of methane also offer good prospects for the production of hydrogen, large-scale applications to generate electric power or the use of CH 4 as a fuel in the transportation sector. New techniques and economic, social and institutional factors determine how fast the use of natural gas will increase. It is expected that 0.54 Tm 3 of natural gas will be needed for the twelve countries of the European Community. Main users in the year 2030 will be the electric power industry (39%), industry (26%), households and trade (18%), and transportation sector and supply (15%). In 2030 63% of natural gas has to be imported. 3 refs

  15. Competition in trade with natural gas

    International Nuclear Information System (INIS)

    1999-01-01

    On 22 June 1998, the European Parliament and the Council of Europe adopted Directive 98/30/EC on common rules for the internal market for natural gas. The Natural Gas Market Directive is aimed at increasing the competition on the gas market and creating an internal market for natural gas. To achieve this, the Directive includes provisions for ensuring that owners of transmission and distribution networks will allow other players access to these networks. The Directive is much more far-reaching and comprehensive than the present Swedish legislation in the field of natural gas. The main task of the committee is to submit a proposal for natural gas legislation that will meet the requirements of the new Directive. According to the committee directives, the work on the new legislation should aim at the regulations serving as a basis for a socio economically efficient market. However, it should also be borne in mind that the Swedish natural gas market is less developed than the markets in most other European countries, and that a lack of equilibrium in the opening of the gas markets should be avoided. Current international deliberations concerning the natural gas network in the Nordic countries and the Baltic Sea region should also be taken into account. Chapter 1 gives more detailed particulars of the points of departure for the work of the committee and the implementation of the work. The report is arranged in the form three main parts, i.e. a background part, a part describing the points of departure, and a proposals part

    1998-01-01

    The development of the gas field off Sable Island and the imminent construction of a gas pipeline which will deliver natural gas to New Brunswick has prompted a thorough examination of energy-related issues in the province. This report presents the findings of the provincial energy committee which examined the implications of the arrival of natural gas to the province. The committee held a series of public hearings and consultations, and also received written submissions. After a historical perspective on natural gas as an energy source in the province and a review of the gas industry participants and their interests, the report discusses such issues as gas pipeline economics, local distribution company operations, infrastructure development, the regulatory framework, energy market competition, regional price equity, development of in-province gas sources, pipeline access, pipeline laterals and expansions, establishment of gas distribution franchises, municipal involvement in gas development, the impact of gas industry development on electric utility restructuring, and the environmental benefits of natural gas. Finally, recommendations are made regarding how natural gas should be regulated and distributed

    After first relating the importance of natural gas storage to the viability of Italian industrial activities, this paper discusses the geo-physical nature of different types of underground cavities which can be used for natural gas storage. These include depleted petroleum and natural gas reservoirs, aquifers and abandoned mines. Attention is given to the geologic characteristics and physical characteristics such as porosity, permeability and pressure that determine the suitability of any given storage area, and to the techniques used to resolve problems relative to partially depleted reservoirs, e.g., the presence of oil, water and salt. A review is made of Italy's main storage facilities. This review identifies the various types of storage techniques, major equipment, operating and maintenance practices. A look is then given at Italy's plans for the development of new facilities to meet rising demand expected to reach 80 billion cubic meters/year by the turn of the century. The operating activities of the two leading participants, SNAM and AGIP, in Italy's natural gas industry are highlighted. Specific problems which contribute to the high operating costs of natural gas storage are identified and a review is made of national normatives governing gas storage. The report comes complete with a glossary of the relative terminology and units of measure

    An overview an update of PanCanadian's exploration operations in Atlantic Canada was presented along with market delivery options. PanCanadian is one of Canada's largest natural gas producers and the most active Canadian driller with 2,479 wells. With its' 94 per cent success rate, the company is emerging as an international exploration success and is marketing energy throughout North America. In terms of marketing natural gas, PanCanadian is ranked twelfth of 68 suppliers in customer satisfaction. The company also markets about 10 per cent of western crude production and is the second largest Canadian marketer for natural gas liquids. Also, with the deregulation of electricity in Alberta, PanCanadian is constructing two 106 megawatt power plants in Alberta to provide electricity to Southern Alberta and to take advantage of the economics of energy conversion. PanCanadian also has a dominant, 20 per cent position in the Scotia Shelf and has plans for offshore processing. Graphs depicting its Deep Panuke operations and pipeline routes to market the natural gas were included. Forecast charts for natural gas demand show a steady increase in demand from 2000 to 2010. tabs., figs

    1998-01-01

    During the last two decades, the natural gas industry has gone through drastic changes. On one hand, deregulation and customer choice have been introduced to the industry. On the other hand, technological advances have resulted in substantial growth of available gas resources. In short, deregulation coupled with increased availability of supply has changed the way market participants interact with each other and which avenues they take to become leaders. Many new opportunities for entry into the market have also been created. As a result, the tide of competition has not only turned against the financially strong giants of the past, but it has also turned against new entrants who are fast, flexible and market driven. Natural gas utilities companies have responded by improving their operational efficiencies through process re-engineering, organizational re-alignment, restructuring and strategic alliances or mergers. Deregulation of the electricity industry is expected to increase competitive pressures on the natural gas industry, thus causing even more of a decrease in natural gas prices. In the future, natural gas utilities must be able to improve their effectiveness by accurately forecasting demand and optimizing their own supply and delivery systems in such a way that costs are minimized without compromising the reliability of supply. The new frontier of competitiveness will ensure that structural changes in the industry are characterized by an effective management of the supply-demand relationship and the optimization of risks inherently a part of gas delivery

  3. Trading in LNG and natural gas

    International Nuclear Information System (INIS)

    1992-01-01

    We have examined the market for natural gas from a number of viewpoints, starting with the role of natural gas in the global energy market where its 20% share of primary energy demand has been captured in the space of almost as many years. In discussion regional energy markets we cover the disparities between supply and demand which give rise to trade by pipeline, and by sea in the form of liquefied natural gas (LNG). Both have in fact increased steadily in recent years, yet even in 1991, only 12-15% of total gas production was traded across international boundaries, whereas for oil it was closer to 40%. For the moment pipeline trade remains heavily concentrated in Europe and North America, and it is in the LNG sector where the spread of projects, both existing and planned, is more global in nature. We examine the development of LNG trades and the implications for shipping. Finally, we look at transportation costs, which are likely to be an important component in the viability of many of the natural gas export schemes now under review. There is good reason to be ''bullish'' about parts of the natural gas industry but this Report suggests that there are areas of concern which could impinge on the development of the market in the 1990s.

  4. Natural gas for utility use appears unstoppable

    Energy Technology Data Exchange (ETDEWEB)

    Stein, H.

    1993-04-01

    Electric demand probably will grow rapidly through 1995, which will force utilities to quickly build substantial new generating capacities, predicted the National Economic Research Associates Inc. (NERA) in December 1992. NERA, a market research firm based in White Plains, NY, also noted this growth would require an increase in coal and hydrogeneration capacities, electrical generation by natural gas. NERA feels environmental pressures, economics and short lead times for gas electric generation plants point to surging consumption during the late 90s into the early 21st century. NERA estimates utilities will burn 200 percent more natural gas by 2005, or up to 7.5-trillion cubic feet (7.5 Tef) in that year. The increased consumption would raise natural-gas-fired electrical capacity to 145 GW by year-end 1995 and 160 GW by 2000. NERA bases its estimate on the price of natural gas at the wellhead remaining below $3/Mcf ($3 per thousand cubic feet in 1991 dollars). NERA and the high growth in electric utility usage would put extreme pressure on the natural gas industry.

    With gasoline being an ever decreasing finite resource and with the desire to reduce humanity's carbon footprint, there has been an increasing focus on innovation of alternative fuel sources. Natural gas burns cleaner, is more abundant, and conforms to modern engines. However, storing compressed natural gas (CNG) requires large, heavy gas cylinders, which limits space and fuel efficiency. Adsorbed natural gas (ANG) technology allows for much greater fuel storage capacity and the ability to store the gas at a much lower pressure. Thus, ANG tanks are much more flexible in terms of their size, shape, and weight. Our ANG tank employs monolithic nanoporous activated carbon as its adsorbent material. Several different configurations of this Flat Panel Tank Assembly (FPTA) along with a Fuel Extraction System (FES) were examined to compare with the mass flow rate demands of an engine.

    Market demand for natural gas in Canada's Maritime provinces was discussed. The Atlantic market represents the largest potential region, currently without access to natural gas in Canada or the United States. Maritimes and Northeast Pipelines and the Sable Offshore Energy partners have made great efforts to introduce and market natural gas as well as to provide pipeline transportation services in the Maritimes and New England markets. Maritimes and Northeast Pipelines is a partnership project with Westcoast Energy, Mobil Oil, and Duke Energy. Theirs is the first pipeline project to deliver gas, but it will certainly not be the last gas project in the region. Maritimes and Northeast Pipelines now has 180,000 MMBtu/day of phased-in Canadian load committed to firm service agreements for delivery in the first 24 months of operation. In addition to these firm service agreements, an additional 60,000 MMBtu/day is signed for future lateral extensions to service emerging markets. figs

    Storage is an important link in the natural gas supply chain. It is a valuable aid to providing the link between remote sources of production and consumption locations. After a brief recall covering the role of storage this article describes the various options for storing natural gas: saline cavities, aquifers, liquefied gas tanks or artificial cavities. A report follows on the different solutions adopted in Europe and in Switzerland, more particularly that chosen by Gaznat in order to contribute to securing supplies in Western Switzerland. Market deregulation has brought changes to the regulations, which are in turn modifying the rules that were in force until just recently, and new topics are arising, such as strategic reserves and pricing rules for stored natural gas.

    2013-01-01

    In this paper we study an advertising campaign launched by the Irish government to induce more energy-efficient behaviour and we assess its effect on residential natural gas consumption. We first analyse changes in the daily consumption of natural gas and find that advertising leaflets had a significant, but short-lived, effect on natural gas consumption. We find no persistent effect of the campaign. We then study three surveys administered to 1000 consumers prior to and during the campaign. This repeated cross-section allows us to determine that the efficiency campaign has increased awareness of behaviours that curb natural gas consumption. However we do not find any significant effect of the campaign on self-reported natural gas-saving behaviour. -- Highlights: •We assess the effect of the Irish Power of One campaign on natural gas consumption. •We analyse consumption (and awareness of behaviours) before and after the campaign launch. •There is an effect on consumers' awareness of how to reduce consumption. •We find a short-run effect of the first year of the campaign, but no long run effect

    The search for new ecological solutions for public transport has given an important role to natural gas for vehicles in the national context. Under current prices of fuel and costs of plants, the management of a bus fleet running on natural gas allows consistent savings, besides reducing the atmospheric pollution of urban centres. Within this context, solutions offered by current technology available on the market are examined. Low polluting emissions are taken into consideration and a complete analysis of costs and savings is reported. Reference is made to the Thermie European programme which calls for fuel diversification, energy conservation and air pollution abatement

  15. Effects of liberalizing the natural gas markets in Western Europe

    International Nuclear Information System (INIS)

    Golombek, R.; Gjelsvik, E.; Rosendahl, K.E.

    1994-01-01

    The aim of this paper is to examine the impact of liberalization of the West-European natural gas markets within a numerical model. The authors study profit maximizing Cournot producers facing an ideal third party access for gas transport in Western Europe. In each country there are two types of end-users, small consumers in the residential, commercial and public sector and large users in the manufacturing industry and in the electric power supply. The analysis proceeds in stages. First the case where no traders exploit arbitrage possibilities and some producers have limited access to the markets is examined. In this equilibrium net prices differ across markets. These differences disappear in the second case where traders are introduced. The third case focuses on a complete European market for natural gas in which traders exploit all arbitrage possibilities and all producers are in a position to sell gas in all markets. The impact on the complete European market of changes in costs of production, costs of transport and costs of distribution is studied. Finally, the impact of banning gas sales consortia in Western Europe is studied. It is shown that this measure increases welfare in Western Europe, whereas profits to non-European producers decrease. 31 refs., 12 tabs

    The high-efficiency boiler and furnace measure produces gas heating savings resulting from installation of more energy-efficient heating equipment in a residence. Such equipment, which ranges in size from 60 kBtu/hr to 300 kBtu/hr, is installed primarily in single-family homes and multifamily buildings with individual heating systems for each dwelling unit. This protocol does not cover integrated heating and water heating units which can be used in lieu of space heating only equipment.

    This study describes the Mexican natural gas industry as it exists today and the factors that have shaped the evolution of the industry in the past or that are expected to influence its progress; it also projects production and use of natural gas and estimates the market for exports of natural gas from the United States to Mexico. The study looks ahead to two periods, a near term (1993--1995) and an intermediate term (1996--2000). The bases for estimates under two scenarios are described. Under the conservative scenario, exports of natural gas from the United States would decrease from the 1992 level of 250 million cubic feet per day (MMCF/d), would return to that level by 1995, and would reach about 980 MMCF/D by 2000. Under the more optimistic scenario, exports would decrease in 1993 and would recover and rise to about 360 MMCF/D in 1995 and to 1,920 MMCF/D in 2000.

  2. Mercury Removal from Natural Gas in Egypt

    International Nuclear Information System (INIS)

    Korkor, H.; AI-Alf, A.; EI-Behairy, S.

    2004-01-01

    Worldwide natural gas is forecasted to be the fastest growing primary energy source. In Egypt, natural gas is recently playing a key role as one of the major energy sources. This is supported by adequate gas reserves, booming gas industry, and unique geographical location. Egypt's current proven gas reserves accounted for about 62 TCF, in addition to about 100 TCF as probable gas reserves. As a result, it was decided to enter the gas exporting market, where gas is transported through pipelines as in the Arab Gas pipelines project and as a liquid through the liquefied natural gas (LNG) projects in Damietta, and ld ku. With the start up of these currently implemented LNG projects that are dealing with the very low temperatures (down to -162 degree c), the gas has to be subjected to a regular analysis in order to check the compliance with the required specifications. Mercury is a trace component of all fossil fuels including natural gas, condensates, crude oil, coal, tar sands, and other bitumens. The use of fossil hydrocarbons as fuels provides the main opportunity for emissions of mercury they contain to the atmospheric environment: while other traces exist in production, transportation and processing systems

  3. Natural gas purchasing for cogeneration projects

    International Nuclear Information System (INIS)

    Kubacki, J. Jr.

    1992-01-01

    This paper reports on the primary cost component for most gas-fired cogeneration or on-site power projects, cost of natural gas. Often gas comprises 50 to 65% of total project costs over the life of the project. Thus it is very important to focus on natural gas sourcing, pricing, transportation and storage. This important task should not be blindly delegated to a gas supplier. The end user must develop a gas strategy that results in the most cost-effective burnertip price. Long-term natural gas supplies are usually source from the three major producing regions: Mod-Continent, Gulf Coast, and Western Canada. A well-reasoned gas strategy must include: determination of transportation and distribution options from the project site to potential gas sources (including direct interconnection of the project to interstate pipelines); acquisition of competitive gas bids from suppliers in appropriate regions; negotiation of potential discounts from interstate pipelines and local distribution companies (LDCs); fine-tuning project economics by, for example, using storage to maximize transportation load factor; and pricing mechanisms that meet economic parameters of the project. This paper uses a hypothetical project in the Midwest to examine the major factors in devising a cost-effective natural gas sourcing

  4. Markets for British Columbia natural gas

    Maerz, D.H.; Coad, L.A.

    1990-11-01

    An evaluation is presented of the outlook for the British Columbia natural gas industry and the fundamentals underlying both the increase in activity and the longer-term outlook for the natural gas sector are examined. The basis for the analysis was the North American Regional Gas (NARG) model, to which a number of modifications were made. The level of natural gas resource assumed for northeastern British Columbia corresponds to an ultimate potential of 50 Tcf. Significant growth in production over the outlook period (1988-2007) is predicted. High rates of utilization on the Westcoast system underscore the need for significant capacity expansion if the production levels projected for the mid-1990s are to be achieved. Natural gas production is projected to be sustained at the 800 billion cubic foot level from the mid-1990s onwards, with the majority of the production growth occurring between 1992 and 1997. Significant growth in exports is projected, especially when capacity is available to move gas supplies directly into the California and Rocky Mountain regions in the US. These two transport corridors represent over half the increase in British Columbia production between 1992 and 1997. 53 refs., 15 figs., 26 tabs

    In recent years, important structural and institutional transformations are observed, for consequence the questions on the energy industries had started to incorporate, the regulation problems. Thus, the simple creation of new regulating agencies does not assure the automatic fulfilment of the functions of public interest. In this new context, these tasks are much more complex, demanding a learning process: how much to the structures of market and how much to the strategical behavior of the companies. In the local scene, to consolidate the distribution of the natural gas for the residential segment is one of the challenges of the Bahiagas, mainly after the publication of the Resolution that will go to establish the General Conditions of Gas Supply Canalized in the Residential Classroom in the State of the Bahia (hearing publishes carried through N. 002/2006 in June/2006). In this context, it is important to deeply understand the Resolution, that consequently will go to print a new dynamics for the Bahiagas. (author)

  7. Estimating household fuel oil/kerosine, natural gas, and LPG prices by census region

    International Nuclear Information System (INIS)

    Poyer, D.A.; Teotia, A.P.S.

    1994-08-01

    The purpose of this research is to estimate individual fuel prices within the residential sector. The data from four US Department of Energy, Energy Information Administration, residential energy consumption surveys were used to estimate the models. For a number of important fuel types - fuel oil, natural gas, and liquefied petroleum gas - the estimation presents a problem because these fuels are not used by all households. Estimates obtained by using only data in which observed fuel prices are present would be biased. A correction for this self-selection bias is needed for estimating prices of these fuels. A literature search identified no past studies on application of the selectivity model for estimating prices of residential fuel oil/kerosine, natural gas, and liquefied petroleum gas. This report describes selectivity models that utilize the Dubin/McFadden correction method for estimating prices of residential fuel oil/kerosine, natural gas, and liquefied petroleum gas in the Northeast, Midwest, South, and West census regions. Statistically significant explanatory variables are identified and discussed in each of the models. This new application of the selectivity model should be of interest to energy policy makers, researchers, and academicians

  9. US crude oil, natural gas, and natural gas liquids reserves: 1990 annual report

    International Nuclear Information System (INIS)

    1991-09-01

    The primary focus of this report is to provide an accurate estimate of US proved reserves of crude oil, natural gas, and natural gas liquids. These estimates were considered essential to the development, implementation, and evaluation of natural energy policy and legislation. In the past, the government and the public relied upon industry estimates of proved reserves. These estimates were prepared jointly by the American Petroleum Institute (API) and the American Gas Association (AGA) and published in their annual report, Reserves of Crude Oil, Natural Gas Liquids, and Natural Gas in the United States and Canada. However, API and AGA ceased publication of reserves estimates after their 1979 report. By the mid-1970's, various federal agencies had separately established programs to collect data on, verify, or independently estimate domestic proved reserves of crude oil or natural gas. Each program was narrowly defined to meet the particular needs of the sponsoring agency. In response to recognized need for unified, comprehensive proved reserves estimates, Congress in 1977 required the Department of Energy to prepare such estimates. To meet this requirement, the EIA's reserves program was undertaken to establish a unified, verifiable, comprehensive, and continuing statistical series for proved reserves of crude oil and natural gas. The program was expanded to include proved reserves of natural gas liquids in the 1979 report. 36 refs., 11 figs., 16 tabs

  10. Natural gas supply in Denmark - A model of natural gas transmission and the liberalized gas market

    International Nuclear Information System (INIS)

    Bregnbaek, L.

    2005-01-01

    In the wake of the liberalization of European energy markets a large area of research has spawned. This area includes the development of mathematical models to analyze the impact of liberalization with respect to efficiency, supply security and environment, to name but a few subjects. This project describes the development of such a model. In Denmark the parallel liberalization of the markets of natural gas and electricity and the existence of an abundance of de-centralized combined heat and power generators of which most are natural gas fired, leads to the natural assumption that the future holds a greater deal of interdependency for these markets. A model is developed describing network flows in the natural gas transmission system, the main arteries of natural gas supply, from a technical viewpoint. This yields a technical bounding on the supply available in different parts of the country. Additionally the economic structure of the Danish natural gas market is formulated mathematically giving a description of the transmission, distribution and storage options available to the market. The supply and demand of natural gas is put into a partial equilibrium context by integrating the developed model with the Balmorel model, which describes the markets for electricity and district heat. Specifically on the demand side the consumption of natural gas for heat and power generation is emphasized. General results and three demonstration cases are presented to illustrate how the developed model can be used to analyze various energy policy issues, and to disclose the strengths and weaknesses in the formulation.

    Natural gas and renewable energy each contribute to economic growth, energy independence, and carbon mitigation, sometimes independently and sometimes collectively. Often, natural gas and renewables are considered competitors in markets, such as those for bulk electricity. This paper attempts to address the question, 'Given near- and long-term needs for abundant, cleaner energy sources and decarbonization, how can more compelling business models be created so that these two domestic forms of energy work in greater concert?' This paper explores revenue opportunities that emerge from systems-level perspectives in 'bulk energy' (large-scale electricity and natural gas production, transmission, and trade) and four 'distribution edge' subsectors: industrial, residential, commercial, and transportation end uses.

  13. The effect of natural gas shortages on the Mexican economy

    OpenAIRE

    Alcaraz, Carlo; Villalvazo Martin, Sergio

    2016-01-01

    The Mexican economy experienced a shortage of natural gas from the second quarter of 2012 through the second half of 2013. In order to deal with this problem, the state-owned national supplier of natural gas (Pemex) implemented a system that restricts the amount of natural gas used by the manufacturing sector. With this information, we have constructed a "shortage index" that represents the percentage of natural gas restricted per month in each region. We quantify the effect of natural gas sh...

  18. The outlook for expansion of the North American market for natural gas: Working together is the key

    International Nuclear Information System (INIS)

    Baly, M. III

    1992-01-01

    A partnership called the Natural Gas Council has been formed in the USA comprising 22 leaders from all segments of the natural gas industry. The Council has a plan, the Natural Gas Initiative, whose goal is to increase natural gas demand in the USA by 2.5 trillion ft 3 by 1996. The plan will also involve cooperation with Canadian companies, since ca 9% of U.S. natural gas supply comes from Canada. Five target areas will account for the increase in short-term annual demand. In the residential sector, 500,000 households will be targeted for conversion from electricity to natural gas water heating. In the commercial and industrial sectors, the plan targets oil-consuming customers as candidates for conversion to natural gas; this alone represents a demand of ca 1.5 trillion ft 3 . A number of nontraditional markets will also be targeted, including natural gas vehicles, natural gas cooling, and electricity generation. Goals include the addition of 50,000 new natural gas vehicles to American roads. It is felt that provisions of the Clean Air Act Amendments of 1990 mandating clean-burning fuels will aid in this effort and in encouraging the installation of gas-fired power plants. It is also hoped to speed up the commercialization of new technologies for gas cooling and gas-fired heat pumps. Cooperation between the Canadian and American gas associations is taking place to achieve common standards and certification procedures for gas appliances. This will open expanded markets for gas-related products. Other USA-Canada goals include increasing the viability of natural gas use in Mexico and formation of cross-border research partnerships for pooling of resources

  19. Methane leakage in natural gas operations

    International Nuclear Information System (INIS)

    Jennervik, A.

    1992-01-01

    The world gas industry is efficient in conservation of natural gas within its systems. As the influence of methane as an infra-red absorbent gas has been more widely recognized, the considerations of methane's greenhouse effect has become vitally important to gas companies around the world. The industry is universally environmentally conscious. natural gas transmission and distribution companies want to maintain their image as suppliers of clean fuel. Further reductions in methane leakage --- particularly in older distribution systems --- can, should and will be pursued. Unfortunately, there has been little exchange of views on methane leakages between commentators on environmental matters and gas companies and organizations. There is absolutely no need for the industry to avoid the issue of greenhouse gases. Without industry involvement, the environmental debate concerning fossil fuels could lead to selective interpretation of scientific views and available evidence. Companies and authorities would be presented with confusing, contradictory evidence on which to base policy approaches and regulations

  20. The future of European natural gas

    International Nuclear Information System (INIS)

    Ausems, D.

    1991-01-01

    Western Europe's natural gas markets abound with opportunities. They also contain major challenges. This paper presents a revealing assessment of both the challenges and the opportunities that arise from those markets. It also explains some of the surprising ways in which the European Commission and Dutch gas industry will influence gas markets throughout the Continent. Gas consumption is well-established and expanding in a small group of European nations. These countries rely on an equally small collection of suppliers, both within and beyond the Community's borders, to provide the required volumes of natural gas. Because supply and demand are likely to grow at significantly different rates, it is suggested what a major market imbalance could materialize before the end of the decade. Averting major gas supply problems beyond the year 2000 will require multi-billion dollar commitments by producers and will necessitate long-term take-or-pay contacts backed by strong and financially healthy buyers

  1. Consortium for Petroleum & Natural Gas Stripper Wells

    Energy Technology Data Exchange (ETDEWEB)

    Joel L. Morrison; Sharon L. Elder

    2007-03-31

    The Pennsylvania State University, under contract to the U.S. Department of Energy (DOE), National Energy Technology Laboratory (NETL), established a national industry-driven Stripper Well Consortium (SWC) that is focused on improving the production performance of domestic petroleum and/or natural gas stripper wells. The SWC represents a partnership between U.S. petroleum and natural gas producers, trade associations, state funding agencies, academia, and the NETL. This document serves as the twelfth quarterly technical progress report for the SWC. Key activities for this reporting period included: (1) Drafting and releasing the 2007 Request for Proposals; (2) Securing a meeting facility, scheduling and drafting plans for the 2007 Spring Proposal Meeting; (3) Conducting elections and announcing representatives for the four 2007-2008 Executive Council seats; (4) 2005 Final Project Reports; (5) Personal Digital Assistant Workshops scheduled; and (6) Communications and outreach.

  2. Natural gas cooling: Part of the solution

    International Nuclear Information System (INIS)

    Jones, D.R.

    1992-01-01

    This paper reviews and compares the efficiencies and performance of a number of gas cooling systems with a comparable electric cooling system. The results show that gas cooling systems compare favorably with the electric equivalents, offering a new dimension to air conditioning and refrigeration systems. The paper goes on to compare the air quality benefits of natural gas to coal or oil-burning fuel systems which are used to generate the electricity for the electric cooling systems. Finally, the paper discusses the regulatory bias that the author feels exists towards the use of natural gas and the need for modification in the existing regulations to provide a 'level-playing field' for the gas cooling industry

  3. FSU's natural gas liquids business needs investment

    International Nuclear Information System (INIS)

    Plotnikov, V.S.; Berman, M.; Angerinos, G.F.

    1995-01-01

    Production of natural gas liquids has fallen seriously behind its potential in the former Soviet Union (FSU). Restoration of the gas liquids business thus represents a rich investment opportunity. Capital, however, must come from international sources, which remain uncertain about the FSU's legal, commercial, and political systems. If these hurdles can be overcome, FSU output of liquid petroleum gas alone might double between 1990 and 2010. In the FSU, LPG is produced from associated and nonassociated natural gas, condensate, and refinery streams. It also comes from what is known in the FSU as ShFLU--a mixture of propane, butane, pentane, and hexane produced at gas processing plants in Western Siberia and fractionated elsewhere. The paper reviews FSU production of gas liquids focusing on West Siberia, gives a production outlook, and describes LPG use and business development

  4. Comparative Assessment Of Natural Gas Accident Risks

    Burgherr, P.; Hirschberg, S.

    2005-01-01

    The study utilizes a hierarchical approach including (1) comparative analyses of different energy chains, (2) specific evaluations for the natural gas chain, and (3) a detailed overview of the German situation, based on an extensive data set provided by Deutsche Vereinigung des Gas- und Wasserfaches (DVGW). According to SVGW-expertise DVGW-data can be regarded as fully representative for Swiss conditions due to very similar technologies, management, regulations and safety culture, but has a substantially stronger statistical basis because the German gas grid is about 30 times larger compared to Switzerland. Specifically, the following tasks were carried out by PSI to accomplish the objectives of this project: (1) Consolidation of existing ENSAD data, (2) identification and evaluation of additional sources, (3) comparative assessment of accident risks, and (4) detailed evaluations of specific issues and technical aspects for severe and smaller accidents in the natural gas chain that are relevant under Swiss conditions.

    A successful NGV industry depends upon the skilled use of prime geographic and economic drivers. But a vital ingredient to a sustained and profitable industry is the pioneering example of the gas suppliers and the combined commercial skills of fleet operators equipment suppliers and government. The use of natural gas for vehicles must be long-term commercially viable both for the vehicles whole life cost and the refuelling stations capital investment. (au)

    International Nuclear Information System (INIS)

    Johnson, J.

    1998-01-01

    Issues regarding the Alberta supply of natural gas were debated. Factors considered include pipeline expansions, storage and foreign exchange. The influence of NYMEX was also cited as an important determinant of gas pricing. Currently, the Western Canada Sedimentary Basin's (WCSB) market share is 22 per cent of the North American demand. The WCSB extends through Alberta, British Columbia, Saskatchewan, the Northwest Territories and the Yukon. The Basin's estimated reserves at the end of 1996 were 65 TCF. tabs., figs

    Conflicts in Nigeria have recently deepened and they show a continuous escalation. The endless attacks against all infrastructures led to a reduction of oil production, thus effecting international oil market as well. This article provides a Nigeria's economy and energy framework. First, we will focus on troubles characterizing oil companies activities in Nigeria. Then, we will analyze how a higher exploitation of natural gas could affect Nigeria's economy, politics and society. [it

  8. Canadian natural gas : market review and outlook

    International Nuclear Information System (INIS)

    2001-01-01

    This annual working paper provides summaries of trends within the North American natural gas industry and also reviews Canadian gas exports. It is designed to promote dialogue between industry and the government and to obtain feedback on natural gas issues. The main section of the report consists of graphs, with limited text comments on the side. It provides a structured look at supply and demand for the year 2000 as well as for the near term (2001) and long-term (2010). The sources of information included private consultants, industry associations and federal agencies in Canada and the United States. It was shown that gas demand had grown steadily in North America since 1997, at about 2.5 per cent annually, and then fell 3.4 per cent in 1998 and remained low in 1999, below 1997 demand. This was due mainly to mild winters. In 2000, the demand for natural gas increased again to 5 per cent as a result of a colder winter and increased gas use for power generation. The report also stated that the combination of various factors including low storage balances due to previously low drilling years and high oil prices, were responsible for natural gas price increases in 2000. The tight supply/demand balance was exacerbated by restraints in pipeline capacity. Producers and pipeline groups are now looking seriously at developing the large gas deposits in Alaska and the Mackenzie Delta which were previously considered to be uneconomic. It was noted that in the near term, storage must be rebuilt to normal levels. Storage balances will be a good indicator of the relative strengths of gas production and demand growth. It was forecasted that Canada to U.S. gas exports should continue to increase in 2001 as a large new export pipeline was completed in 2000, but there is considerable uncertainty for the medium to longer-term. refs., tabs., figs

    The past three years, Mitchell Energy and Development Corp. has undergone a massive restructuring that has changed the face of one of the nation's largest and best-known natural gas/natural gas liquids companies. Facing a rapidly changing industry that frequently has been stung by volatile swings in energy markets, management of the independent company, founded by George Mitchell in 1946, sold off $300 million in non-core assets; reduced its long-term debt by $400 million; instituted a hiring freeze and reduced its workforce by a third, from 2,900 to 1,950, over the last three years. Mitchell negotiated a buyout of its hugely profitable North Texas gas sales contract with Natural Gas Pipeline Company of America as a means of easing its transition to a market-sensitive price environment and reducing its debt. Mitchell also took operational control. Finally, Mitchell has left the real estate business, culminating July 31 with the sale of its real estate subsidiary, The Woodlands Corporation, for $543 million ($460 million net after-tax), further reducing its workforce to 1,100. On Aug. 18, the company said it will use the proceeds to repurchase common stock, retire another $200 million of public debt, make asset niche energy acquisitions and increase capital spending for existing programs. The result is a renewed focus on its exploration and production and gas gathering, processing and marketing businesses

    1983-01-01

    To the extent that there are market imperfections and other constraints limiting consumption of gas to levels significantly below those dictated by underlying economic factors of cost and producibility, society bears the cost resulting from misallocation of resources and avoidable environmental deterioration. Given the regulatory and institutional setting within which the natural gas industry has been forced to operate, there is a strong presumption that such inhibitions on gas use may in fact exist. Some rigidities stem undoubtedly from characteristics unique to gas as a natural-resource commodity. This report presents a framework for reviewing potential sources of constraints, rigidities, and distortions in the functioning of natural gas markets under the Natural Gas Policy Act of 1978 (NGPA) and other legislation. The organizing principle and primary focus of the paper are the sequence of transactions between wellhead and point of consumption, with major attention to industrial and power plant use. The transactions in question are between: producers and pipelines; pipelines and distributors; distributors and end users; and pipelines and industrial end users (mainline sales). In addition to these vertical transactions, there are horizontal transactions between pipelines (off-system sales) and between distributors. 22 references, 1 figure, 1 table.

  12. The natural gas industry in Portugal

    2004-01-01

    This article makes a synthesis of the evolution of the natural gas sector in Portugal since the end of the 1990's. The aim of the energy policy of Portugal was the creation of a liberalized energy market capable to ensure the security of the energy supplies and to encourage the energy efficiency in order to reduce the environmental impact. The success of the introduction of natural gas in Portugal perfectly fulfills these goals. Since 1997, the natural gas consumption has increased significantly. The start-up of the methane terminal of Sines allows the diversification of the supply sources and contributes to the growth of the offer. The opening of the market is under development. It will allow the main consumers to select their supplier among those present on the Portuguese market. GALP company should keep its leader position and its daughter company 'Gas du Portugal' should reach 300 MW of power generation capacities by 2005 with the development of multi-energy services. The creation of an Iberian energy market between Spain and Portugal should speed up in 2004 leading to deep modifications in the energy sector of southern Europe. (J.S.)

    1993-01-01

    In view of the rapid pace of population growth in industrializing nations and the globalization of many commercial markets, cumulative environmental damages have heightened the responsibility of industrialized nations to use science and technology to help other nations achieve desirable levels of economic prosperity and environmental quality. For all nations, the challenge of sustainable development will be to use natural resources in an economic and equitable manner that results in minimum environmental impact over time. For these reasons, the expanded use of natural gas will continue to be prominent in the debate about policy alternatives for advancing sustainable development. As the cleanest burning fossil fuel, natural gas and its attendant supply and distribution infrastructure are characterized as important for many reasons including: Reducing greenhouse gas emissions, generating minimal solid and liquid wastes during production, transportation, and consumption; serving as a transition fuel to a future with greater reliance on renewable energy sources; and for providing an industrial base for developing more environmentally conscious technologies. Other arguments for its expanded use have emphasized the opportunity to induce technical innovations and behavioral changes that are more compatible with sustainable development. The criteria by which society can design sustainable development strategies and determine whether environmental quality goals have been met will be key to the effective implementation of clean-fuel programs and expansion of natural-gas uses. This issue is timely, particularly with regard to how clean fuels can be nested within conceptual policy and planning frameworks that address sustainable industrial development more broadly. 35 refs.

    The article tries about the Center of Commercialization of Gas-CCG located in Bogota where experts take charge minute to minute that and that fuel that ECOPETROL sells arrives every day to its final destination. They work 24 hours during 365 days, they receive and they respond in time their clients' record applications, they analyze rates; they sell, they negotiate, they give the prices, but the mainly, they control the key that guarantees that the Colombians receive the supply of natural gas on time. It has the most modern tip technology and a complete system of compute that allows knowing the requirements of the buyers in real time. From there they decide that natural gas will be made every day and they detect quickly where flaws are presented. The CCG sells every month an average of $35.000 millions. Although the thermal plants are the biggest buyers of natural gas in the country, some industrial clients and big companies have begun the conversion of their teams to make use of this fuel, recognized in the world to be more economic and cleaner for the environment

    Full text: Chemical-technology approaches allowing to intensification the prevention processes of gas hydrates formation at motion of gas-liquid stream of natural gas in system natural gas well - gas wire have been worked up. Technological regimes of treatment of gas stream have been determined. Linear correlation dependences inhibitor electrolytes contained hydrated ions with different ion radii and charges of subgroups of alkali elements with one - type electron configuration were obtained. Important physico-chemical parameters of electrolytes have been determined: activity; coefficients of activity, viscosity, diffusion; density; heat capacity; heat conductivity; surface tension and freezing-point. The features of continuous influence of inhibitory factors on process of gas flow at low temperatures and relatively high pressure differences ΔP have been studied by using of technological installation modulating the system natural gas well - gas wire. The dependences of gas quantity flowing from installation on ΔP at low temperatures have been studied with consideration of real states of process of gas - liquid phase flowing. Obtained experimental data for non-inhibitory and inhibitory processes have been compared under the same conditions. It was established that more high intensification of prevention process of gas hydrates formation is observed at the same thermodynamic conditions due to continuous treatment of gas by methanol and polyvinyl alcohol, which are absorbed into the bentonite, by glycigol, absorbed into the silica gel, and by calcium chloride. Vibration conjugate process of gas hydrates formation and break-up taking place in gas-liquid system with using of membrane electrode of electrochemical cell has been found. Periodic vibrations of membrane potential have been found at treatment of natural gas by methanol at low temperatures. Periodic character of vibration effect is determined by conjugate variations of equilibrium concentrations of components

    1993-01-01

    Thirty four years ago the natural gas field Slochteren in Groningen, Netherlands made the Netherlands into an outstanding natural gas country. Last summer, exactly half of the original 2680 trillion m 3 of natural gas has been extracted. According to the projections of the Dutch Gasunie the Dutch gas reserves will be about depleted after another thirty four years. To guarantee continuity of the natural gas supply the natural gas will have to become more expensive. Also considerable investments in storage capacity are needed. Comments and opinions of experts regarding the future of the Dutch natural gas market are presented. 2 figs., 14 ills

    1993-01-01

    One of the primary goals of this research effort was to document and compare the economic and environment benefits of using natural gas for pollution control in boilers, furnaces and internal combustion engines, with conventional control technologies. The study indicated that replacement of 15% of the coal used in coal-fired boilers employed in the generation of electric power in the US, with natural gas, would considerably reduce the emissions of acid rain precursors such as sulfur and nitrogen oxides, and do so in a cost-effect manner. The reductions achieved were also in concordance with the reductions in sulfur dioxide emissions mandated by the new Clean Air Act (CAA) Amendments of 1990. The combustion of natural gas would also produce less carbon dioxide as compared to the combustion of coal with an equivalent amount of heat content. Carbon dioxide is a greenhouse gas, i.e., it is believed to play a major role in global warming. Natural gas technology therefore presents a cost-effective step in the eventual mitigation of two of the main environmental problems presently facing us, acid rain, and global warming

    Energy consumption in residential heating using a heat pump driven by an internal combustion engine is discussed. A natural gas rotary engine was developed as a drive unit for a heat pump with 120 to 150 kW heating capacity. The engine was derived from an automotive prototype engine; it had an output of 50 kW at 6000 rpm. The efficiency was improved by an increased compression ratio and a rotor recess suitable for natural gas operation. The engine used specially developed spark plugs and high performance lubrication oil. To obtain longevity, the trochoid surface and the side housing surface were coated with a plasma spray wear coating, ceramic apex seals were used and the accessories were redesigned.

  19. Hydrogen-Enhanced Natural Gas Vehicle Program

    Hyde, Dan; Collier, Kirk

    2009-01-22

    The project objective is to demonstrate the viability of HCNG fuel (30 to 50% hydrogen by volume and the remainder natural gas) to reduce emissions from light-duty on-road vehicles with no loss in performance or efficiency. The City of Las Vegas has an interest in alternative fuels and already has an existing hydrogen refueling station. Collier Technologies Inc (CT) supplied the latest design retrofit kits capable of converting nine compressed natural gas (CNG) fueled, light-duty vehicles powered by the Ford 5.4L Triton engine. CT installed the kits on the first two vehicles in Las Vegas, trained personnel at the City of Las Vegas (the City) to perform the additional seven retrofits, and developed materials for allowing other entities to perform these retrofits as well. These vehicles were used in normal service by the City while driver impressions, reliability, fuel efficiency and emissions were documented for a minimum of one year after conversion. This project has shown the efficacy of operating vehicles originally designed to operate on compressed natural gas with HCNG fuel incorporating large quantities of exhaust gas recirculation (EGR). There were no safety issues experienced with these vehicles. The only maintenance issue in the project was some rough idling due to problems with the EGR valve and piping parts. Once the rough idling was corrected no further maintenance issues with these vehicles were experienced. Fuel economy data showed no significant changes after conversion even with the added power provided by the superchargers that were part of the conversions. Driver feedback for the conversions was very favorable. The additional power provided by the HCNG vehicles was greatly appreciated, especially in traffic. The drivability of the HCNG vehicles was considered to be superior by the drivers. Most of the converted vehicles showed zero oxides of nitrogen throughout the life of the project using the State of Nevada emissions station.

  20. Methane emissions from the natural gas industry

    1993-01-01

    The U.S. EPA and the United Nation's Intergovernmental Panel on Climate Change (IPCC) have suggested that global warming could be reduced if more energy was generated using natural gas rather than fuels such as coal. An increased use of natural gas instead of coal would decrease global warming since methane emits less carbon dioxide (CO 2 ) than any fossil fuel. However, methane is a more potent as a greenhouse gas than CO 2 , and leakage from the gas system could reduce or eliminate the inherent advantage of natural gas. For this reason, methane emissions must be quantified before a national policy on preferred fuels is developed. Therefore, GRI and EPA have developed this confunded program to quantify methane emissions from the U.S. gas industry. This paper presents, for general industry review, the approach and methodology that the project is using to determine the emissions. The study will measure or calculate all gas industry methane emissions - from production at the wellhead, through the system, to the customer's meter. When these data are combined with data from other studies, a definitive comparison of the relative environmental impact of using methane versus other fuels will be possible. The study will also provide data that can be used by the industry to identify cost-effective mitigation techniques to reduce losses. The methane emissions project is being conducted in three phases: the first two phases have identified and ranked all known potential methane-emitting sources and established methods for measuring, calculating, and extrapolating emissions from those sources. The third phase, which is currently in progress, will gather sufficient data to achieve the accuracy goal. This paper briefly summarizes the methodology being used for the completion of the third phase

    1995-06-01

    Norway is rich in gas resources. In recent years, gas sales from the Norwegian continental shelf have been in the order of 25 to 30 billion Sm 3 /yr and are expected to increase strongly the next 10 to 15 years. However, a scattered population, a difficult topography, long distances between large potential consumers and where the gas is brought ashore, make it difficult to utilize the gas commercially in this country. Moreover, the gas will have to compete with a highly developed hydro-electric network. This report evaluates possibilities and hindrances in the establishment of a home market for natural gas in Norway. The low population density implies that using gas for preheating of water, heating of rooms etc will not become important except, perhaps, locally, where gas may be available for other reasons. As a source of energy and raw material in many industrial processes, natural gas can become important in some coastal areas and in central parts of eastern Norway. Discussions are in progress on gas power stations for electricity production. This has aroused some controversy because of environmental problems, and for political acceptance gas power will have to replace coal power. As a fuel, gas may be of interest for domestic ferries and for busses. A lack of capital under financial risk and gas prices limit the market development. Although tax policy is presently favourable to gas power, the risk taken by private investors in converting to natural gas is increased by their not knowing for how long the gas will be exempt from environmental tax. 74 refs., 8 figs., 27 tabs

  2. Environmental benefits of natural gas for buses

    International Nuclear Information System (INIS)

    Rabl, A.

    2002-01-01

    This paper presents a life cycle assessment comparing diesel buses with buses fueled by natural gas. The data for the emission of pollutants are based on the MEET Project of the European Commission (EC), supplemented by data measured for diesel and gas buses in Paris. The benefits of the gas fueled bus are then quantified using the damage cost estimates of the ExternE Project of the EC. A diesel bus with emissions equal to Standard EURO2 of the EC is compared with the same bus equipped with a natural gas engine, for use in Paris and in Toulouse. The damage cost of a diesel bus is significant, in the range of 0.4-1.3 euro/km. Natural gas allows an appreciable reduction of the emissions, lowering the damage cost by a factor of about 2.5 (Toulouse) to 5.5 (Paris). An approximate rule is provided for transferring the results to other cities. A sensitivity analysis is carried out to evaluate the effect of the evolution of the emissions standard towards EURO3, 4 and 5, as well as the effect of uncertainties. Finally a comparison is presented between a EURO2 diesel bus with particle filter, and a gas fueled bus with the MPI engine of IVECO, a more advanced and cleaner technology. With this engine the damage costs of the gas fueled bus are about 3-5 times lower than those of the diesel with particle filter, even though the latter has already very low emissions.(author)

    Buses, operating within a Florence (Italy) municipal transportation system, and equipped with Otto cycle engines, were selected for retrofitting taking into account the suitability of each vehicle's specific routing and service requirements. Cost benefit analyses indicated that it wouldn't be economically feasible to retrofit buses equipped with diesel engines. A computerized refuelling system was set up at the fleet's central service station which was hooked up to the natural gas utility's supply line. This paper tables the cost benefit analysis data comparing gasoline and methane operation and reflecting the cost savings which are expected to be accrued through this methanization program over a span of 14 years

    The gas industry has its problems. Its estimates for the future have been run over by the energy conservation trend. Contracts considered to be safe did not come off, and the cost of new contracts was much higher than expected. The gas supply contract with Russia - already celebrated as a German contribution to the easing of tension between East and West - remains a price problem. Consumers will have to pay so much for natural gas that utilities begin to fear district heating, the cost of which will be even higher.

    In discussing the impact of Federal Energy Regulatory Commission (FERC) Order 636, the latest rule on the restructuring and deregulation of the US natural gas industry, the effect of interest rates on the success of the FERC policy is often overlooked. The thesis of this paper is that interest rates play an important role in integrating seasonal gas markets and in stimulating investment in storage infrastructure. We propose a model to analyse the equilibrium condition for an efficient gas market. Also analysed are the implications of pipeline rate design of FERC 636 for gas despatch decisions. (author)

    2006-03-31

    Environmental and economic benefits could accrue from a safe, above-ground, natural-gas storage process allowing electric power plants to utilize natural gas for peak load demands; numerous other applications of a gas storage process exist. A laboratory study conducted in 1999 to determine the feasibility of a gas-hydrates storage process looked promising. The subsequent scale-up of the process was designed to preserve important features of the laboratory apparatus: (1) symmetry of hydrate accumulation, (2) favorable surface area to volume ratio, (3) heat exchanger surfaces serving as hydrate adsorption surfaces, (4) refrigeration system to remove heat liberated from bulk hydrate formation, (5) rapid hydrate formation in a non-stirred system, (6) hydrate self-packing, and (7) heat-exchanger/adsorption plates serving dual purposes to add or extract energy for hydrate formation or decomposition. The hydrate formation/storage/decomposition Proof-of-Concept (POC) pressure vessel and supporting equipment were designed, constructed, and tested. This final report details the design of the scaled POC gas-hydrate storage process, some comments on its fabrication and installation, checkout of the equipment, procedures for conducting the experimental tests, and the test results. The design, construction, and installation of the equipment were on budget target, as was the tests that were subsequently conducted. The budget proposed was met. The primary goal of storing 5000-scf of natural gas in the gas hydrates was exceeded in the final test, as 5289-scf of gas storage was achieved in 54.33 hours. After this 54.33-hour period, as pressure in the formation vessel declined, additional gas went into the hydrates until equilibrium pressure/temperature was reached, so that ultimately more than the 5289-scf storage was achieved. The time required to store the 5000-scf (48.1 hours of operating time) was longer than designed. The lower gas hydrate formation rate is attributed to a

    Natural gas consumption only rose by 1.3%, down from an average growth of 2.8% per year in the previous decade. Natural gas still suffers in particular from severe competition with coal in the power generation sector. Inside the EU-28, actual consumption was estimated down 1.9% to 460 Billion cubic metres (Bcm). This poor performance brought European consumption to levels not seen in more than 15 years. In the US, rising gas prices compared to 2012 has often made coal more competitive and penalized gas consumption in the power generation sector, causing it to fall by 10.5%. Global growth in natural gas has been increasingly constrained by supply. In 2013, the growth in gas production slowed substantially to 0.8%, bringing the total volume to 3377 Bcm. As before, the gas supply shortfall was due to the decline of mature and conventional fields, and an insufficient renewal of reserves. The lack of upstream investment is especially acute in emerging markets, due to a lack of a favourable regulatory and fiscal climate. The moderation of natural gas supply and investment has also been increasingly driven by geopolitical challenges. Deterioration of security, internal conflicts and resulting damage to infrastructures have caused some production outages and supply disruptions in some countries. In 2013, marketed production fell especially heavily in Africa (Algeria, Nigeria, Libya and Egypt). With the exception of Europe, other regions posted positive production gains. The largest of them were recorded in the CIS (+ 2.7%) and the Middle East (+ 3.4%). International gas trade increased significantly by 2.1% to 1048 Bcm, due to the growing dependence of consumer markets on increasingly distant production sources, sometimes located in economically and politically unstable areas. The rise in the international gas trade was only driven by inter-regional pipeline gas exports from the CIS to Europe (+ 15%) and China (+ 36%). Geopolitical risks are having an ever

    This article evaluates the prospects for achieving a competitive market in the natural gas industry, according to the common rules for the internal market established by the Directive 98/30/CE of 22 June 1998. Firstly, for the organisation of the access to the system, the regulated, rather than the negotiated, procedure would ensure a better opportunity to promote competition in the market. Secondly, the establishment of a competitive market calls for the effective separation of the phases of production characterized by natural monopoly from the phases which may be developed in a competitive setting [it

    1995-01-01

    Under the A greement on Natural Gas Markets and Prices of October 1985, the Canadian federal government agreed to deregulate the price of natural gas and to allow a competitive gas market to develop. Several beneficial changes that have occurred as a result of the deregulation were described, including the Industrial Gas Users Association's (IGUA) view on the marketing and sale of natural gas by local gas distributor's (LDC) and the sale within the LDC franchise. IGUA's support for the separation between LDC distribution and LDC sales and marketing activities as the last step in deregulation process, was explained. Several arguments for the opposing view were also discussed. Recommendations were made for effective separation of LDC distribution and LDC sales/marketing activities

  16. Methods of natural gas liquefaction and natural gas liquefaction plants utilizing multiple and varying gas streams

    Wilding, Bruce M; Turner, Terry D

    2014-12-02

    A method of natural gas liquefaction may include cooling a gaseous NG process stream to form a liquid NG process stream. The method may further include directing the first tail gas stream out of a plant at a first pressure and directing a second tail gas stream out of the plant at a second pressure. An additional method of natural gas liquefaction may include separating CO.sub.2 from a liquid NG process stream and processing the CO.sub.2 to provide a CO.sub.2 product stream. Another method of natural gas liquefaction may include combining a marginal gaseous NG process stream with a secondary substantially pure NG stream to provide an improved gaseous NG process stream. Additionally, a NG liquefaction plant may include a first tail gas outlet, and at least a second tail gas outlet, the at least a second tail gas outlet separate from the first tail gas outlet.

  19. Role of natural gas in meeting an electric sector emissions ...

    Science.gov (United States)

    With advances in natural gas extraction technologies, there is an increase in availability of domestic natural gas, and natural gas is gaining a larger share of use as a fuel in electricity production. At the power plant, natural gas is a cleaner burning fuel than coal, but uncertainties exist in the amount of methane leakage occurring upstream in the extraction and production of natural gas. At high leakage levels, these methane emissions could outweigh the benefits of switching from coal to natural gas. This analysis uses the MARKAL linear optimization model to compare the carbon emissions profiles and system-wide global warming potential of the U.S. energy system over a series of model runs in which the power sector is asked to meet a specific CO2 reduction target and the availability of natural gas changes. Scenarios are run with a range of upstream methane emission leakage rates from natural gas production. While the total CO2 emissions are reduced in most scenarios, total greenhouse gas emissions show an increase or no change when both natural gas availability and methane emissions from natural gas production are high. Article presents summary of results from an analyses of natural gas resource availability and power sector emissions reduction strategies under different estimates of methane leakage rates during natural gas extraction and production. This was study was undertaken as part of the Energy Modeling Forum Study #31:

  6. Papers of the Canadian Institute's forum on natural gas purchasing strategies : critical information for natural gas consumers in a time of diminishing natural gas supplies and higher prices

    International Nuclear Information System (INIS)

    2003-01-01

    This conference provided insight into how to prosper in an increasingly complex natural gas marketplace. The presentations from key industry players offered valuable information on natural gas purchasing strategies that are working in the current volatile price environment. Diminishing natural gas supplies in North America mean that higher prices and volatility will continue. Other market challenges stem from potential cost increases in gas transportation, unbundling of natural gas services, and the changing energy marketing environment. The main factors that will affect prices for the winter of 2004 were outlined along with risk management and the best pricing strategies for businesses. The key strategies for managing the risks associated with natural gas purchase contracts were also reviewed, along with the issue of converging natural gas and electricity markets and the impact on energy consumers. The conference featured 15 presentations, of which 4 have been indexed separately for inclusion in this database. refs., tabs., figs

    1995-12-31

    The overall objective of this research project is to develop a catalytic process to convert natural gas to liquid transportation fuels. The process, called the HSM (Hydrogen Sulfide-Methane) Process, consists of two steps that each utilize a catalyst and sulfur-containing intermediates: (1) converting natural gas to CS{sub 2} and (2) converting CS{sub 2} to gasoline range liquids. Catalysts have been found that convert methane to carbon disulfide in yields up to 98%. This exceeds the target of 40% yields for the first step. The best rate for CS{sub 2} formation was 132 g CS{sub 2}/kg-cat-h. The best rate for hydrogen production is 220 L H{sub 2} /kg-cat-h. A preliminary economic study shows that in a refinery application hydrogen made by the HSM technology would cost $0.25-R1.00/1000 SCF. Experimental data will be generated to facilitate evaluation of the overall commercial viability of the process.

  8. Natural gas markets in the Pacific Rim

    International Nuclear Information System (INIS)

    Hertzmark, D.I.

    1991-01-01

    In the 1980s, Asian energy markets expanded at a rapid rate to meet the surge in demand from Japan, South Korea, and Taiwan. This demand boom coincided with an increase in non-OPEC oil production in the region. As oil production stabilizes, demand appears to be surging again, but this time in the Southeast Asian countries. Natural gas will play a key role in this expansion of energy use and could start to lead rather than follow the oil market. This will be especially true as compressed natural gas and oxygenates start to take significant shares of the transportation fuel markets, while the role of residual fuel oil is increasingly usurped by gas for environmental reasons. Many new gas sources such as Papua New Guinea, Siberia, China, and Canada will fight for market share while domestic demand in Indonesia and Malaysia takes up increasing proportions of those countries' gas production. Extensive regional transportation schemes are likely to direct more of the gas output of Southeast Asia to intra-ASEAN uses. 2 tabs

  9. Emissions credits from natural gas vehicles

    International Nuclear Information System (INIS)

    Anderson, J.F.; Kodjak, D.

    1997-01-01

    Dedicated natural gas vehicles (NGVs) often are capable of testing to lower than federally required engine certification standards. NGVs often meet inherently low emission vehicle (ILEV) and ultra low emission vehicle (ULEV) standards. Over the useful life of the vehicle, a significant amount of mobile source emission reduction credits (MSERCs) can be generated. This paper will discuss key elements of establishing a workable methodology to quantify the emissions benefits generated through the purchase and use of heavy-duty natural gas vehicles instead of heavy-duty diesel vehicles. The paper will focus on a public fleet of transit buses owned by the Massachusetts Bay Transit Agency, the Massachusetts Port Authority, and a private fleet of waste haulers. Public fleets may generate emission credits as a key compliance option to offset emission shortfalls from changes to the Employee Commute Options (ECO) program, the Inspection and Maintenance program, and facilitate annual surface transportation conformity. Private fleets may generate emission credits for open market trading to area and stationary sources seeking to buy credits from mobile sources, where allowed by EPA and state policy

    The rapid deployment of hydraulic fracturing and horizontal drilling technologies enabled the production of previously uneconomic shale gas resources in North America. Global deployment of these advanced gas production technologies could bring large influx of economically competitive unconventional gas resources to the energy system. It has been hoped that abundant natural gas substituting for coal could reduce carbon dioxide (CO2) emissions, which in turn could reduce climate forcing. Other researchers countered that the non-CO2 greenhouse gas (GHG) emissions associated with shale gas production make its lifecycle emissions higher than those of coal. In this study, we employ five state-of-the-art integrated assessment models (IAMs) of energy-economy-climate systems to assess the full impact of abundant gas on climate change. The models show large additional natural gas consumption up to +170% by 2050. The impact on CO2 emissions, however, is found to be much smaller (from -2% to +11%), and a majority of the models reported a small increase in climate forcing (from -0.3% to +7%) associated with the increased use of abundant gas. Our results show that while globally abundant gas may substantially change the future energy market equilibrium, it will not significantly mitigate climate change on its own in the absence of climate policies.

    The ARES program was initiated in 2001 to improve the overall brake thermal efficiency of stationary, natural gas, reciprocating engines. The ARES program is a joint award that is shared by Dresser, Inc., Caterpillar and Cummins. The ARES program was divided into three phases; ARES I (achieve 44% BTE), ARES II (achieve 47% BTE) and ARES III (achieve 50% BTE). Dresser, Inc. completed ARES I in March 2005 which resulted in the commercialization of the APG1000 product line. ARES II activities were completed in September 2010 and the technology developed is currently being integrated into products. ARES III activities began in October 2010. The ARES program goal is to improve the efficiency of natural gas reciprocating engines. The ARES project is structured in three phases with higher efficiency goals in each phase. The ARES objectives are as follows: 1. Achieve 44% (ARES I), 47% (ARES II), and 50% brake thermal efficiency (BTE) as a final ARES III objective 2. Achieve 0.1 g/bhp-hr NOx emissions (with after-treatment) 3. Reduce the cost of the produced electricity by 10% 4. Improve or maintain reliability, durability and maintenance costs

  12. Environmental Impact of Natural Gas Hydrate Production

    Max, M. D.; Johnson, A. H.

    2017-12-01

    Unmet conventional energy demand is encouraging a number of deep energy importing nations closer to production of their potentially very large Natural Gas Hydrate (NGH) resources. As methane and other natural gases are potent greenhouse gases, concerns exist about the possible environmental risks associated NGH development. Accidental of natural gas would have environmental consequences. However, the special characteristics of NGH and production models indicate a very low environmental risk from the reservoir to the deepwater wellhead that is much lower than for conventional deepwater gas. NGH is naturally stable in its solid form in the reservoir and shutting in the gas can be achieved by stopping NGH conversion and gas production in the reservoir. Rapid shut down results in re-crystallization of gas and stabilization of the reservoir through NGH reformation. In addition, new options for innovative technologies have the potential to allow safe development of NGH at a fraction of the current estimated cost. Gas produced from NGH is about the same as processed conventional gas, although almost certainly more pure. Leakage of gas during transport is not a production issue. Gas transport leakage is a matter for best practices regulation that is rigorously enforced.

  13. Nordic cooperation within natural gas research

    Nordic cooperation within natural gas research is discussed. A reorganization of this cooperation has recently taken place. It is explained that common Nordic resources are now to be concentrated within 7 areas, one of which is the area of energy/industrial policies, regional policies and agriculture and forestry, all under the common heading of ''Economy''. The plan of activities within this area includes international cooperation within the European Communities, the European Energy Charter, the International Energy Agency and will involve the energy policy situation in eastern Europe and the Baltic countries, the electric power and natural gas markets in the northern countries, energy related environmental questions and Nordic energy research cooperation. Nordic research activities constitute 2% of research resources within the OECD. The basis for Nordic research cooperation (for example a common cultural background) is described, and suggestions are made as to how it should be administrated. The Nordic energy research programme for 1991-1994 embodies bioenergy and the environment, fuel cells, energy and the society, solid fuels, district heating and petroleum technology. The status report for the nordic gas market, which represents the Nordic gas companies' evaluation of the Nordic gas market, is summarized, and Nordic research activities related to gas utilization are shortly commented upon.

  14. Natural gas in the World 2014

    2014-01-01

    This document summarizes the key findings of the 160-page 2014 edition of CEDIGAZ's flagship survey 'Natural Gas in the World': Worldwide proved natural gas reserves grew by 0.5% (981 bcm) in 2013. On January 1, 2014, reserves were estimated by Cedigaz to stand at 200,576 bcm, compared to 199,595 bcm for the previous year. Out of the seven regions in our regional breakdown, only North America and the C.I.S. have seen an increase in their reserves base in 2013. The strongest gain, both in absolute terms (+739 bcm) and as a percentage (+6.8%), was recorded in North America, reflecting the growth of unconventional gas reserves, both in the U.S. and Canada. The C.I.S. also posted a solid 669 bcm increase, representing a 1% rise. OPEC countries control about half of the world's gas reserves (47%) whereas C.I.S. countries account for almost one-third (33%). Proved unconventional gas reserves are concentrated in North America, especially in the U.S., which held in particular 3.7 tcm of proven shale gas reserves. Outside North America, large coal bed methane (CBM) reserves also exist in Australia and China. Marketed production was up by only 1% from 2012, reaching 3394 bcm, compared to the average growth rate for the last ten years (2.5%/year). This slowdown is partly explained by growing coal-togas competition on the demand side and a gas supply shortfall on the supply side, especially in emerging markets, where the lack of upstream investment is acute. The highest production increases were recorded in the Middle East (+3.1%) and the C.I.S. (+2.6%), which compensated for output losses in Europe (-2.3%) and Africa (-6.6%). In 2013, the two leading regional producing markets, North America and the C.I.S., accounted for 26% and 24% of global production respectively, followed by the Middle East (17%) and Asia Oceania (15%). In 2013, growth in unconventional gas production was driven by North America, China and Australia. North America no longer accounts

    From a geological perspective, deep natural gas resources are generally defined as resources occurring in reservoirs at or below 15,000 feet, whereas ultra-deep gas occurs below 25,000 feet. From an operational point of view, ''deep'' is often thought of in a relative sense based on the geologic and engineering knowledge of gas (and oil) resources in a particular area. Deep gas can be found in either conventionally-trapped or unconventional basin-center accumulations that are essentially large single fields having spatial dimensions often exceeding those of conventional fields. Exploration for deep conventional and unconventional basin-center natural gas resources deserves special attention because these resources are widespread and occur in diverse geologic environments. In 1995, the U.S. Geological Survey estimated that 939 TCF of technically recoverable natural gas remained to be discovered or was part of reserve appreciation from known fields in the onshore areas and State waters of the United. Of this USGS resource, nearly 114 trillion cubic feet (Tcf) of technically-recoverable gas remains to be discovered from deep sedimentary basins. Worldwide estimates of deep gas are also high. The U.S. Geological Survey World Petroleum Assessment 2000 Project recently estimated a world mean undiscovered conventional gas resource outside the U.S. of 844 Tcf below 4.5 km (about 15,000 feet). Less is known about the origins of deep gas than about the origins of gas at shallower depths because fewer wells have been drilled into the deeper portions of many basins. Some of the many factors contributing to the origin of deep gas include the thermal stability of methane, the role of water and non-hydrocarbon gases in natural gas generation, porosity loss with increasing thermal maturity, the kinetics of deep gas generation, thermal cracking of oil to gas, and source rock potential based on thermal maturity and kerogen type.

    The natural gas futures market is fundamental to the current natural gas market both as means of price discovery and for price hedging. Thus, the informational efficiency of the futures market is an important issue. This article re-examines the informational efficiency of the natural gas futures market. In this re-examination several cash price series are considered. It is found that the natural gas futures market is informationally efficient for only one of the cash markets. The characteristics of the current natural gas market that might explain the estimated results are also discussed. (author)

    Proven natural gas reserves and production in the USA have continued to increase in recent years. This is due to the exploration of shale formations and the expanded use of hydraulic fracking technology. Looking forward, we can expect that high crude oil prices will sustain natural gas production at current levels (approximately 25% of natural gas production in the USA is a by-product of crude oil drilling), and the natural gas liquid cuts are priced with crude oil. Continued drilling in the near term for natural gas is required by lease obligations and by commitments to investors

    Due to its clean burning properties, low investment costs and flexibility in production, natural gas is often put forward as the ideal partner fuel for wind power and other renewable sources of electricity generation with strongly variable output. This working paper examines three vital questions associated with this premise: 1) Is natural gas indeed the best partner fuel for wind power? 2) If so, to what extent will an increasing market share of wind power in European electricity generation affect demand for natural gas in the power sector? and 3) Considering the existing European natural gas markets, is natural gas capable of fulfilling this role of partner for renewable sources of electricity?.

    2018-03-01

    Full Text Available In this study, an energy efficiency studies have been carried out in a natural gas-fired rolling mill annealing furnace of an industrial establishment. In this context, exhaust gas from the furnace has been examined in terms of waste heat potential. In the examinations that have been made in detail; waste heat potential was found as 3.630,31 kW. Technical and feasibility studies have been carried out to realize electricity production through an Organic Rankine Cycle (ORC system for evaluating the waste heat potential of the annealing furnace. It has been calculated that 1.626.378,88 kWh/year of electricity can be generated by using the exhaust gas waste heat of the annealing furnace through an ORC system to produce electric energy with a net efficiency of 16%. The financial value of this energy was determined as 436.032,18 TL/year and the simple repayment period of the investment was 8,12 years. Since the annealing period of the annealing furnace is 2800 hours/year, the investment has not been found to be feasible in terms of the feasibility studies. However, the investment suitability can be assured when the annealing furnace is operating at full capacity for 8,000 hours or more annually.

  3. Does Increased Extraction of Natural Gas Reduce Carbon Emissions?

    International Nuclear Information System (INIS)

    Aune, F.R.; Golombek, R.; Kittelsen, S.A. C.

    2004-01-01

    Without an international climate agreement, extraction of more natural gas could reduce emissions of CO2 as more 'clean' natural gas may drive out ''dirty'' coal and oil. Using a computable equilibrium model for the Western European electricity and natural gas markets, we examine whether increased extraction of natural gas in Norway reduces global emissions of CO2. We find that both in the short run and in the long run total emissions are reduced if the additional quantity of natural gas is used in gas power production in Norway. If instead the additional quantity is exported directly, total emissions increase both in the short run and in the long run. However, if modest CO2-taxes are imposed, increased extraction of natural gas will reduce CO2 emissions also when the additional natural gas is exported directed

    2014-05-01

    Full Text Available The article tries to present the place and role played by the Middle East region on the international market of natural gas due to its high potential of production and export. Important gas reserves are not extracted due to poor infrastructure, difficult technical conditions and lack of needed investments. But the main problem which creates great obstacles for the capitalization of gas resources and impedes the countries’ development and export is the conflictual situation persisting in the region for many decades. Instead of cooperation one can see a permanent confrontation which seriously harms the social and economic progress, and that is why democratic and responsible regimes are required, with a new vision upon international relations, but also it is needed the economic, financial and technological support of the great powers, in particular of USA and EU, that is essential and extremely beneficial for the future of this region.

    Past decade and current status of development of natural gas vehicles (NGVs) in China is described. By the end of 1995, 35 CNG refueling stations and 9 LPG refueling stations had been constructed in 12 regions, and 33,100 vehicles had been converted to run on CNG or LPG. China`s automobile industry, a mainstay of the national economy, is slated for accelerated development over next few years. NGVs will help to solve the problems of environment protection, GHGs mitigation, and shortage of oil supply. The Chinese government has started to promote the development of NGVs. Projects, investment demand, GHG mitigation potential, and development barriers are discussed. China needs to import advanced foreign technologies of CNGs. China`s companies expect to cooperate with foreign partners for import of CNG vehicle refueling compressors, conversions, and light cylinders, etc.

    International Nuclear Information System (INIS)

    Maertens, L.; Koschack, A.

    1999-01-01

    This paper describes a low-energy house in Zittau, Germany. The house consists of two parts A and B. Part A is heated by means of gas boilers and condensed boilers, while part B is solar heated. Energy for heating and warming of tap water is an important part of the primary energy consumption in Germany. Therefore, one way of reducing the CO2 emissions is to reduce the heat losses of buildings through outer facades and air ventilation, to use regenerative energy sources, to use fuels with low CO2 emissivity like natural gas, and to install efficient heating- and hot water preparation systems. The low-energy house in Zittau is used for energy research

    Today, natural gas covers 16% of primary energy demand in Europe. Consumption of this fuel is set at about 380 billion cubic meters to which we can add about 700 billion consumed in the ex-COMECON countries. Europe's consumption alone is forecasted by many to rise to 500 billion cubic meters at the turn of the century and to 600 billion by the year 2010. It is expected that the power plant sector will account for one-third of this rise in consumption. Even if domestic production of this fuel is maximized and foreign suppliers maintain their production trends, the expected demand increases in industriali--ed countries can be sufficiently satisfied only by recourse to new suppliers located in the far reaches of the globe

    The liquefaction of offshore natural gas is a relatively new technology, and years of intensive research and development indicate that it is now feasible. But problems can occur in the phase of merchandising the cryogenic liquid. In this context, the necessary steps start with the intermediate product storage which maybe integrated in the liquefaction platform, or which possibly has to be on an external structure. The product transfer from the platform to the exporting tanker is another problem area. The paper deals with the principle design features of the liquefaction plant's supporting structure (barge, semisubmersible or fixed platform). Special emphasize is given to the technical, the operational and the economic aspects of the product transfer from the offshore liquefaction site to the coastal terminal and these considerations are summarized under the heading merchandising.

    This report provided details of updates to the wood ethanol pathway recently added to the GHGenius model, an analytical tool used to analyze emissions from conventional and alternative fuel combustion processes. The pathway contains data developed by the United States Department of Energy. A number of co-products were added to the wood and agricultural residue pathways, including furfural, xylitol, lignin, and glycerol. New chemical inputs included nitrogen gas, ammonia, enzymes and yeast. Biological ethanol pathways were reviewed, and separate inputs for wood, agricultural residues, corn ethanol, and wheat ethanol were added. The model was updated to reflect current research conducted on the gasification of wood and the upgrading of the gas to produce pipeline quality natural gas. New process developments in producing pipeline quality gas from coal were also added. The ability to model enzyme consumption was added to all ethanol pathways. 25 refs., 41 tabs., 8 figs.

    The evolution of the price of natural gas (NG) is examined in industrial and tertiary residential sectors for European Union (EU) countries. The methodological approach is that of comparative analysis. NG price is seen to be positively correlated to prices of liquid fuels. NG price in the tertiary residential sector is significantly higher than that for the industrial sector for all countries examined. An attempt is undertaken to examine tax policies for NG and liquid fuels. All governments of EU countries have the policy of not applying direct taxes to the NG industrial price. They have also taken measures to support its penetration in the residential tertiary sector by applying lower taxes than those on liquid fuels. (author)

    Natural gas extraction, often referred to as “fracking,” has increased rapidly in the U.S. in recent years. To address potential health impacts, passive air samplers were deployed in a rural community heavily affected by the natural gas boom. Samplers were analyzed for 62 polycyclic aromatic hydrocarbons (PAHs). Results were grouped based on distance from each sampler to the nearest active well. PAH levels were highest when samplers were closest to active wells. Additionally, PAH levels closest to natural gas activity were an order of magnitude higher than levels previously reported in rural areas. Sourcing ratios indicate that PAHs were predominantly petrogenic, suggesting that elevated PAH levels were influenced by direct releases from the earth. Quantitative human health risk assessment estimated the excess lifetime cancer risks associated with exposure to the measured PAHs. Closest to active wells, the risk estimated for maximum residential exposure was 2.9 in 10,000, which is above the U.S. EPA's acceptable risk level. Overall, risk estimates decreased 30% when comparing results from samplers closest to active wells to those farthest. This work suggests that natural gas extraction may be contributing significantly to PAHs in air, at levels that are relevant to human health. PMID:25810398

    The natural gas supply in the Netherlands will experience a capacity problem once the pressure of the natural gas field Slochteren in the province Groningen will decrease below a certain level. It is expected that this will already happen in the winter of 1996. Underground storage of natural gas reserves is considered to be the only appropriate solution to accommodate this problem. Four environmental organizations in the Netherlands ordered GASTEC, the Dutch research center for natural gas technology, to study the alternatives for natural gas storage in the Netherlands. 7 figs

  15. Year Ahead Demand Forecast of City Natural Gas Using Seasonal Time Series Methods

    Directory of Open Access Journals (Sweden)

    2016-09-01

    Full Text Available Consumption of natural gas, a major clean energy source, increases as energy demand increases. We studied specifically the Turkish natural gas market. Turkey’s natural gas consumption increased as well in parallel with the world‘s over the last decade. This consumption growth in Turkey has led to the formation of a market structure for the natural gas industry. This significant increase requires additional investments since a rise in consumption capacity is expected. One of the reasons for the consumption increase is the user-based natural gas consumption influence. This effect yields imbalances in demand forecasts and if the error rates are out of bounds, penalties may occur. In this paper, three univariate statistical methods, which have not been previously investigated for mid-term year-ahead monthly natural gas forecasting, are used to forecast natural gas demand in Turkey’s Sakarya province. Residential and low-consumption commercial data is used, which may contain seasonality. The goal of this paper is minimizing more or less gas tractions on mid-term consumption while improving the accuracy of demand forecasting. In forecasting models, seasonality and single variable impacts reinforce forecasts. This paper studies time series decomposition, Holt-Winters exponential smoothing and autoregressive integrated moving average (ARIMA methods. Here, 2011–2014 monthly data were prepared and divided into two series. The first series is 2011–2013 monthly data used for finding seasonal effects and model requirements. The second series is 2014 monthly data used for forecasting. For the ARIMA method, a stationary series was prepared and transformation process prior to forecasting was done. Forecasting results confirmed that as the computation complexity of the model increases, forecasting accuracy increases with lower error rates. Also, forecasting errors and the coefficients of determination values give more consistent results. Consequently

  16. Natural gas supply strategies for European energy market actors

    International Nuclear Information System (INIS)

    Girault, Vincent

    2007-06-01

    The liberalization of the European energy markets leads to the diversification of supplies. Hence, we analyse the natural gas importation problem in a power producer point of view. Upstream and downstream natural gas markets are concentrated. In this oligopoly context, our topic is to focus on strategies which modify natural gas sourcing price. This by studying the surplus sharing on the natural gas chain. A European firm can bundle gas and electricity outputs to increase its market share. Therefore, a bundling strategy of a power producer in competition with a natural gas reseller on the final European energy market increases upstream natural gas price. Bundling also acts as a raising rival cost strategy and reduces the rivals' profit. Profits opportunities incite natural gas producers to enter the final market. Vertical integration between a natural gas producer and a European gas reseller is a way, for producers, to catch end consumer surplus. Vertical integration results in the foreclosure of the power producer on the upstream natural gas market. To be active on the natural gas market, the power producer could supply bundles. But, this strategy reallocates the rent. The integrated firm on natural gas gets the rent of electricity market in expenses of the power producer. Then, a solution for the power producer is to supply gas and electricity as complements. Then, we consider a case where vertical integration is not allowed. Input price discrimination by a monopolist leads to a lower natural gas price for the actor which diversifies its supplying sources. Furthermore, a bundling strategy increases the gap between the price proposed to the firm which also diversify its output and the firm which is fully dependent from the producer to supply natural gas on final market.

    All the qualities of gas - available, affordable, efficient, acceptable and reliable - make this energy a cornerstone both for the development of emerging countries and for new economic activities. Another advantage is that gas is available everywhere in a gaseous and/or liquid form, according to the particular infrastructure (gas pipeline, gas tankers). Moreover, gas can be consumed in different sectors - residential, commercial or industrial - and for different uses - electricity generation or clean fuel for transportation. A first part of this paper presents the natural gas resources Worldwide (Cedigaz data) while a second part reviews the development around the world of the use of gas - liquefied petroleum gas (LPG) and natural gas - as alternative fuels

    Riva, A.; Occhio, L.; Andreetto, B.

    1998-01-01

    The production of atmospheric pollutants in combustion processes depends on plant characteristic, combustion conditions and fuel quality. The influence of fuel quality on the emission of sulphur oxides, nitrogen oxides, carbon monoxide, dust and carbon dioxide and on the emission of some toxic pollutants, such as heavy metals and polycyclic aromatic hydrocarbons, is analysed. The comparison between the emission limits, fixed by the Italian legislation, and the uncontrolled pollutant emissions, produced by fossil fuel combustion in power plants and industrial use, shows that, in order to comply with the limits, a reduction of pollutant emissions is required through the use of abatement systems and cleaner fuels where natural gas has a primary role. The use of cleaner fuels is particularly required in heating plants and appliances for the residential sector, where the development of new gas technologies further increases the environmental advantages of natural gas in comparison with other fuels [it

  1. Formation rate of natural gas hydrate

    Energy Technology Data Exchange (ETDEWEB)

    Mork, Marit

    2002-07-01

    The rate of methane hydrate and natural gas hydrate formation was measured in a 9.5 litre stirred tank reactor of standard design. The experiments were performed to better understand the performance and scale-up of a reactor for continuous production of natural gas hydrates. The hydrate formation rate was measured at steady-state conditions at pressures between 70 and 90 bar and temperatures between 7 and 15 deg C. Between 44 and 56 % of the gas continuously supplied to the reactor was converted to hydrate. The experimental results show that the rate of hydrate formation is strongly influenced by gas injection rate and pressure. The effect of stirring rate is less significant and subcooling has no observable effect on the formation rate. Hydrate crystal concentration and gas composition do not influence the hydrate formation rate. Observations of produced hydrate crystals indicate that the crystals are elongated, about 5 micron in diameter and 10 micron long. Analysis of the results shows that the rate of hydrate formation is dominated by gas-liquid mass transfer. A mass transfer model, the bubble-to-crystal model, was developed for the hydrate formation rate in a continuous stirred tank reactor, given in terms of concentration driving force and an overall mass transfer coefficient. The driving force is the difference between the gas concentration at the gas-liquid interface and at the hydrate crystal surface. These concentrations correspond to the solubility of gas in water at experimental temperature and pressure and the solubility of gas at hydrate equilibrium temperature and experimental pressure, respectively. The overall mass transfer coefficient is expressed in terms of superficial gas velocity and impeller power consumption, parameters commonly used in study of stirred tank reactors. Experiments and modeling show that the stirred tank reactor has a considerable potential for increased production capacity. However, at higher hydrate production rates the

    1995-12-01

    The extent to which Canadian and U.S. natural gas markets have become integrated in the post-deregulation era was assessed. This assessment was accomplished through a statistical analysis of the price movements in Canadian and U.S. gas markets. The analysis pointed to three broad conclusions: (1) on the whole, there has been an increasing degree of integration among North American natural gas markets since price deregulation and the introduction of open access, (2) there is somewhat of a split between eastern and western markets, (3) Alberta's links are stronger with the western U.S. natural gas market than with the market in the eastern U.S. Several factors were cited as contributing to the general increase in market integration, including: (1) increased pipeline capacity and additional pipeline interconnections, coupled with the development of market hubs, (2) improved flexibility of access to pipeline transportation services, (3) improved access to market information and greater trading flexibility which has been facilitated by growing use of electronic bulletin boards and electronic trading systems. The increased market integration was claimed to have benefited both consumers and producers, and to have increased competition in both countries.. 28 refs., 14 figs

    The efficient and effective movement of natural gas from producing regions to consuming regions requires an extensive and elaborate transportation system. In many instances, natural gas produced from a particular well has to travel a great distance to reach its point of use. The transportation system for natural gas consists of a complex network of pipelines designed to quickly and efficiently transport the gas from its origin to areas of high demand. The transportation of natural gas is closely linked to its storage: If the natural gas being transported is not immediately required, it can be put into storage facilities until it is needed. A description of the natural gas transmission, storage, and distribution (TS&D) sector is provided as follows.

  16. Energy resource potential of natural gas hydrates

    2002-01-01

    The discovery of large gas hydrate accumulations in terrestrial permafrost regions of the Arctic and beneath the sea along the outer continental margins of the world's oceans has heightened interest in gas hydrates as a possible energy resource. However, significant to potentially insurmountable technical issues must be resolved before gas hydrates can be considered a viable option for affordable supplies of natural gas. The combined information from Arctic gas hydrate studies shows that, in permafrost regions, gas hydrates may exist at subsurface depths ranging from about 130 to 2000 m. The presence of gas hydrates in offshore continental margins has been inferred mainly from anomalous seismic reflectors, known as bottom-simulating reflectors, that have been mapped at depths below the sea floor ranging from about 100 to 1100 m. Current estimates of the amount of gas in the world's marine and permafrost gas hydrate accumulations are in rough accord at about 20,000 trillion m3. Disagreements over fundamental issues such as the volume of gas stored within delineated gas hydrate accumulations and the concentration of gas hydrates within hydrate-bearing strata have demonstrated that we know little about gas hydrates. Recently, however, several countries, including Japan, India, and the United States, have launched ambitious national projects to further examine the resource potential of gas hydrates. These projects may help answer key questions dealing with the properties of gas hydrate reservoirs, the design of production systems, and, most important, the costs and economics of gas hydrate production.

    A decision support model is presented which will give utilities the support tools to manage the purchasing of natural gas supplies in the most cost effective manner without reducing winter safety stocks to below minimum levels. In Business As Usual (BAU) purchasing quantities vary with the daily forecasts. With Material Requirements Planning (MRP) and Linear Programming (LP), two types of factors are used: seasonal weather and decision rule. Under current practices, BAU simulation uses the least expensive gas source first, then adding successively more expensive sources. Material Requirements Planning is a production planning technique which uses a parent item master production schedule to determine time phased requirements for component points. Where the MPS is the aggregate gas demand forecasts for the contract year. This satisfies daily demand with least expensive gas and uses more expensive when necessary with automatic computation of available-to-promise (ATP) gas a dispacher knows daily when extra gas supplies may be ATP. Linear Programming is a mathematical algorithm used to determine optimal allocations of scarce resources to achieve a desired result. The LP model determines optimal daily gas purchase decisions with respect to supply cost minimization. Using these models, it appears possible to raise gross income margins 6 to 10% with minimal additions of customers and no new gas supply.

    1998-01-01

    The very dynamic economies of Southeast Asia have recently been experiencing a rapid increase in energy demand. Parallel to this development, there has been an increase in the utilization of indigenous natural gas resources. This article reviews gas-pricing policies in the region, which partly explain the rise in gas utilization. Although diverse, energy pricing policies in Southeast Asia address the common objective of enhancing domestic gas production and utilization. The article concludes that a more rational gas-pricing policy framework is emerging in the region. In global terms, gas pricing in the region tends to converge in a market-related framework, despite the many different pricing objectives of individual countries, and the predominance of non-economic pricing objectives in certain countries (especially gas-rich nations). Specifically, governments have been flexible enough to follow global trends and initiate changes in contractual agreements (pricing and profit-sharing), giving oil companies more favourable terms, and encouraging continued private investment in gas development. At the same time, promotional pricing has also been used to increase utilization of gas, through set prices and adjusted taxes achieving a lower price level compared to substitute fuels. For an efficient gas-pricing mechanism, refinements in the pricing framework should be undertaken, as demand for gas approaches existing and/or forecast production capacities. (author)

The overall objectives for the project were: (1) To develop, fabricate and test prototype laboratory devices using sonication and underwater plasma to remove scale from natural gas storage well piping and perforations; (2) To modify the laboratory devices into units capable of being used downhole; (3) To test the capability of the downhole units to remove scale in an observation well at a natural gas storage field; (4) To modify (if necessary) and field harden the units and then test the units in two pressurized injection/withdrawal gas storage wells; and (5) To prepare the project's final report. This report covers activities addressing objectives 1-3. Prototype laboratory units were developed, fabricated, and tested. Laboratory testing of the sonication technology indicated that low-frequency sonication was more effective than high-frequency (ultrasonication) at removing scale and rust from pipe sections and tubing. Use of a finned horn instead of a smooth horn improves energy dispersal and increases the efficiency of removal. The chemical data confirmed that rust and scale were removed from the pipe. The sonication technology showed significant potential and technical maturity to warrant a field test. The underwater plasma technology showed a potential for more effective scale and rust removal than the sonication technology. Chemical data from these tests also confirmed the removal of rust and scale from pipe sections and tubing. Focusing of the underwater plasma's energy field through the design and fabrication of a parabolic shield will increase the technology's efficiency. Power delivered to the underwater plasma unit

    Natural gas is seen by many as the future of American energy: a fuel that can provide energy independence and reduce greenhouse gas emissions in the process. However, there has also been confusion about the climate implications of increased use of natural gas for electric power and transportation. We propose and illustrate the use of technology warming potentials as a robust and transparent way to compare the cumulative radiative forcing created by alternative technologies fueled by natural gas and oil or coal by using the best available estimates of greenhouse gas emissions from each fuel cycle (i.e., production, transportation and use). We find that a shift to compressed natural gas vehicles from gasoline or diesel vehicles leads to greater radiative forcing of the climate for 80 or 280 yr, respectively, before beginning to produce benefits. Compressed natural gas vehicles could produce climate benefits on all time frames if the well-to-wheels CH(4) leakage were capped at a level 45-70% below current estimates. By contrast, using natural gas instead of coal for electric power plants can reduce radiative forcing immediately, and reducing CH(4) losses from the production and transportation of natural gas would produce even greater benefits. There is a need for the natural gas industry and science community to help obtain better emissions data and for increased efforts to reduce methane leakage in order to minimize the climate footprint of natural gas.

    This paper constitutes a follow-up to the one published in this journal in 2004 (no. 562). In this update we describe the new regulations introduced in the Spanish natural gas sector and analyse the behaviour of the market since then. From this study we can deduce that the liberalization of the Spanish natural gas market has led to an oligopoly of suppliers of natural gas. As the Government has liberalized final prices of natural gas, distributors have been able to increase the margin between final prices and the average import price paid for this gas. (author)

  5. Debunking the myths: Natural gas and SO2 allowance solutions

    1993-01-01

    During the decade of the 1990's and beyond, natural gas is expected to be the fuel of choice for a significant portion of new generation capacity. Natural gas already enjoys a greater than 50% market share as a fuel source in the non-regulated cogeneration and Independent Power Producer market. With the new administration in Washington, increased environmental focus will likely increase the attractiveness of natural gas based capacity expansions. While these various issues may appear to contribute to making this decade, the decade for natural gas, there are a number of challenges that must be met if the natural gas and power generation industries are going to satisfy the ever increasing needs of the marketplace. These challenges include: (1) myths of natural gas supply availability, (2) transportation and operational coordination issues, (3) uncertainty of price and reliability, and (4) natural gas for NO x and SO 2 compliance. The author believes that these challenges are actively being met and that there are existing solutions already being offered and incorporated into contracts by natural gas suppliers. The focus of this paper is how electric utilities need to become comfortable with the new natural gas industry and how services can be structured to meet these challenges of serving the electric market requirements

    2001-01-01

    By reviewing the statistics of BP Amoco on natural gas reserves, production and usage, it is easy to see that Russia and USA, both being large natural gas producers, differ significantly from each other. The natural gas reserves of USA are 6th largest in the world, simultaneously the natural gas consumption and import are largest in the world. About one third of the known natural gas reserves of the world are in Russia. The known natural gas reserves of both USA and Canada have decreases, but they have potential gas reserves left. Known natural gas reserves of the USA have been calculated to be sufficient for 9 years consumption at present usage and those of Canada for 11 years. The reserves of Algeria correspond to the usage of 55 years, and the Russian reserves for are about 83 years. Annual production figures of both Russia and the USA are nearly the same. Russia is the largest exporter (125.5 billion m 3 ) of natural gas and the USA the largest importer (96 billion m 3 ). The natural gas reserves of the largest European producers, the Netherlands and Norway have been estimated to be sufficient for use of about 20 years, but those of Great Britain only for about 10 years. The annual production of Russia has varied in the 1990s between nearly 600 billion m 3 and present 550 billion m 3 , the minimum being in 1997 only about 532 billion m 3 . Ten largest natural gas consumers use 67% of the natural gas consumed annually in the world. USA consumes about 27% of the total natural gas produced in the world, the amount of Russia being 364 billion m 3 (16%). Other large natural gas consumers are Great Britain, Germany, Japan, Ukraine, Canada, Italy, Iran and Uzbekistan. The share of these countries of the total consumption varied in between 2-4%. Only Japan has no natural gas production of its own. The foreign trade between Japan and Indonesia is trade on LNG. On the other hand the natural gas consumption of the world's 10th largest producer Norway is nearly zero, so

  12. Natural Gas in the World 2012

    International Nuclear Information System (INIS)

    2012-01-01

    On 1 January 2012, proved natural gas reserves grew by 1.7% over revised reserves of 2011 and were estimated at 199.6 trillion cubic meters (bcm), according to CEDIGAZ. The Commonwealth of Independent states (CIS) made the largest contribution to this growth, essentially as a result of reserves additions/re-evaluation by Russia. The Middle East also showed a significant increase (+ 565 bcm), led by Iran and Saudi Arabia. In North America, shale gas reserves continue to post a sustained growth. Whereas 72% of oil reserves are held by OPEC members, the bulk of gas reserves are distributed between OPEC countries, with 47.6% of the world total, and in the C.I.S. with 32.4%. These two economic blocks thus share responsibility for closing the future world gas balance. World production increased significantly in 2011 to adapt to the expansion of gas demand in a large number of markets, with the exception of Europe, where demand collapsed. World gross production increased 2% in 2011 to 4127 bcm, of which 449.5 bcm was reinjected, 126.5 bcm was flared and 253 bcm was lost through shrinkage. World marketed production climbed 2.8% to reach a new record level of 3299 bcm in 2011. This growth corresponds to the average recorded in the past-ten years. The Middle East recorded the strongest production growth in volume terms (+ 44 bcm), overtaking Asia Oceania to become the third largest producing regional market. North America and the CIS bolstered their standing as the leading producing regions, accounting for 25.6% and 24.9% of global output respectively. For the second consecutive year, the large majority of the volumetric growth in gas supply was led by three countries: the US, Qatar and Russia. In addition, China and Iran improved their rankings. Production of shale gas in the US pursued an exponential growth in 2011, under the impetus of the Haynesville and Marcellus fields. Shale gas represent 30% of the country's gas output today.

    The Holden gas-fired furnace is used in the enriched uranium recovery process to dry and combust small batches of combustibles. The ash is further processed. The furnace operates by allowing a short natural gas flame to burn over the face of a wall of porous fire brick on two sides of the furnace. Each firing wall uses two main burners and a pilot burner to heat the porous fire brick to a luminous glow. Regulators and orifice valves are used to provide a minimum gas pressure of 4 in. water column at a rate of approximately 1,450 scf/h to the burners. The gas flow rate was calculated by determining the gas flow appropriate for the instrumentation in the gas line. Observed flame length and vendor literature were used to calculate pilot burner gas consumption. Air for combustion, purging, and cooling is supplied by a single blower. Rough calculations of the air-flow distribution in piping entering the furnace show that air flow to the burners approximately agrees with the calculated natural gas flow. A simple on/off control loop is used to maintain a temperature of 1,000 F in the furnace chamber. Hoods and glove boxes provide contamination control during furnace loading and unloading and ash handling. Fan EF-120 exhausts the hoods, glove boxes, and furnace through filters to Stack 33. A review of the furnace safety shows that safety is ensured by design, interlocks, procedure, and a safety system. Recommendations for safety improvements include installation of both a timed ignition system and a combustible-gas monitor near the furnace. Contamination control in the area could be improved by redesigning the loading hood face and replacing worn gaskets throughout the system. 33 refs., 16 figs

    Full Text Available With rapid growth of natural gas consumption in China, it is in urgent need of more accurate and reliable models to make a reasonable forecast. Considering the limitations of the single model and the model uncertainty, this paper presents a combinative method to forecast natural gas consumption by Bayesian Model Averaging (BMA. It can effectively handle the uncertainty associated with model structure and parameters, and thus improves the forecasting accuracy. This paper chooses six variables for forecasting the natural gas consumption, including GDP, urban population, energy consumption structure, industrial structure, energy efficiency and exports of goods and services. The results show that comparing to Gray prediction model, Linear regression model and Artificial neural networks, the BMA method provides a flexible tool to forecast natural gas consumption that will have a rapid growth in the future. This study can provide insightful information on natural gas consumption in the future.

    Natural gas is a promising alternative fuel to meet strict engine emission regulations in many countries. Natural gas engines can operate at lean burn and stoichiometric conditions with different combustion and emission characteristics. In this paper, the operating envelope, fuel economy, emissions, cycle-to-cycle variations in indicated mean effective pressure and strategies to achieve stable combustion of lean burn natural gas engines are highlighted. Stoichiometric natural gas engines are briefly reviewed. To keep the output power and torque of natural gas engines comparable to those of their gasoline or Diesel counterparts, high boost pressure should be used. High activity catalyst for methane oxidation and lean deNOx system or three way catalyst with precise air-fuel ratio control strategies should be developed to meet future stringent emission standards

    This article aims to analyze the possibility of insertion of hydrogen in the vehicular natural gas or even the insertion of the hydrogen in the compressed natural gas used in Brazil. For the production of this hydrogen, the spilled turbinable energy from Itaipu would be harnessed. The calculation of production can be extended to other power plants which are close to the natural gas pipelines, where the hydrogen would be introduced. Then, it was analyzed the consumption of natural gas in vehicles in Brazil, the regulation of transportation, the sales of compressed natural gas to fuelling station, the specifications that the piped gas should follow to be sold, and how much hydrogen could be accepted in the mix.

    For the foreseeable future, most of the demand for natural gas in the United States will be met with domestic resources. Impediments, or constraints, to developing, producing, and delivering these resources can lead to price increases or supply disruptions. Previous analyses have identified lack of access to natural gas resources on federal lands as such an impediment. However, various other environmental constraints, including laws, regulations, and implementation procedures, can limit natural gas development and production on both federal and private lands. This report identifies and describes more than 30 environmental policy and regulatory impediments to domestic natural gas production. For each constraint, the source and type of impact are presented, and when the data exist, the amount of gas affected is also presented. This information can help decision makers develop and support policies that eliminate or reduce the impacts of such constraints, help set priorities for regulatory reviews, and target research and development efforts to help the nation meet its natural gas demands.

    The United States has more oil and gas wells than any other country. As of December 31, 2004, there were more than half a million producing oil wells in the United States. That is more than three times the combined total for the next three leaders: China, Canada, and Russia. The Stripper Well Consortium (SWC) is a partnership that includes domestic oil and gas producers, service and supply companies, trade associations, academia, the Department of Energy’s Strategic Center for Natural Gas and Oil (SCNGO) at the National Energy Technology Laboratory (NETL), and the New York State Energy Research and Development Authority (NYSERDA). The Consortium was established in 2000. This report serves as a final technical report for the SWC activities conducted over the May 1, 2004 to December 1, 2011 timeframe. During this timeframe, the SWC worked with 173 members in 29 states and three international countries, to focus on the development of new technologies to benefit the U.S. stripper well industry. SWC worked with NETL to develop a nationwide request-for-proposal (RFP) process to solicit proposals from the U.S. stripper well industry to develop and/or deploy new technologies that would assist small producers in improving the production performance of their stripper well operations. SWC conducted eight rounds of funding. A total of 132 proposals were received. The proposals were compiled and distributed to an industry-driven SWC executive council and program sponsors for review. Applicants were required to make a formal technical presentation to the SWC membership, executive council, and program sponsors. After reviewing the proposals and listening to the presentations, the executive council made their funding recommendations to program sponsors. A total of 64 projects were selected for funding, of which 59 were fully completed. Penn State then worked with grant awardees to issue a subcontract for their approved work. SWC organized and hosted a total of 14 meetings

  13. Canadian natural gas market dynamics and pricing : an update

    International Nuclear Information System (INIS)

    2002-10-01

    This energy market assessment (EMA) report discusses natural gas price formation and describes the current functioning of regional gas markets in Canada. This EMA also describes the factors affecting the price of natural gas in Canada and examines natural gas markets on a region-by region basis. It is shown that as part of an integrated North American market, prices of natural gas in Canada reflect supply and demand factors in both Canada and the United States. During the low oil price period of 1997/1998, high demand for natural gas outpaced the supply because of low drilling and production activity by producers. In response to the increased demand and lower levels of supply, the price of natural gas increased significantly in 1999 and 2000. This was followed by a period of market adjustment. The importance of electronic trading systems for enhancing price discovery was also discussed with reference to how spot and futures markets allow market participants to manage price volatility. It was determined that Canadians have had access to natural gas on terms and conditions equal to export customers, and at equal pricing. In early November 2000, natural gas prices in North American began to rise due to low levels of natural gas in storage. The price shocks were felt unevenly across the North American market. In response to the high prices, consumers conserved energy use, and many industrial users switched to cheaper fuels. By the spring 2001, demand continued to decrease at a time when production was high. These factors contributed to the downward pressure on gas prices. This EMA discusses the structure of market transactions and market adjustment mechanisms. It is presented in the context of the approaching 2002/2003 winter season where the tightening between natural gas supply and demand is expected to result in price volatility. 28 figs

    The main goal of this small-scale project is to investigate oxy-combustion of natural gas (NG) through advanced modeling, in which radiation, chemistry and mixing will be reasonably resolved. 1) A state-of-the-art review was given regarding the latest R and D achievements and status of oxy-fuel technology. The modeling and simulation status and achievements in the field of oxy-fuel combustion were also summarized; 2) A computer code in standard c++, using the exponential wide band model (EWBM) to evaluate the emissivity and absorptivity of any gas mixture at any condition, was developed and validated in detail against data in literature. A new, complete, and accurate WSGGM, applicable to both air-fuel and oxy-fuel combustion modeling and applicable to both gray and non-gray calculation, was successfully derived, by using the validated EWBM code as the reference mode. The new WSGGM was implemented in CFD modeling of two different oxy-fuel furnaces, through which its great, unique advantages over the currently most widely used WSGGM were demonstrated. 3) Chemical equilibrium calculations were performed for oxy-NG flame and air-NG flame, in which dissociation effects were considered to different degrees. Remarkable differences in oxy-fuel and air-fuel combustion were revealed, and main intermediate species that play key roles in oxy-fuel flames were identified. Different combustion mechanisms are compared, e.g., the most widely used 2-step global mechanism, refined 4-step global mechanism, a global mechanism developed for oxy-fuel using detailed chemical kinetic modeling (CHEMKIN) as reference. 4) Over 15 CFD simulations were done for oxy-NG combustion, in which radiation, chemistry, mixing, turbulence-chemistry interactions, and so on were thoroughly investigated. Among all the simulations, RANS combined with 2-step and refined 4-step mechanism, RANS combined with CHEMKIN-based new global mechanism for oxy-fuel modeling, and LES combined with different combustion

    This report summarizes the methodology and models developed to assess the risk to energy delivery from the potential loss of underground gas storage (UGS) facilities located within the United States. The U.S. has a total of 418 existing storage fields, of which 390 are currently active. The models estimate the impacts of a disruption of each of the active UGS facilities on their owners/operators, including (1) local distribution companies (LDCs), (2) directly connected transporting pipelines and thus on the customers in downstream States, and (3) third-party entities and thus on contracted customers expecting the gas shipment. Impacts are measured across all natural gas customer classes. For the electric sector, impacts are quantified in terms of natural gas-fired electric generation capacity potentially affected from the loss of a UGS facility. For the purpose of calculating the overall supply risk, the overall consequence of the disruption of an UGS facility across all customer classes is expressed in terms of the number of expected equivalent residential customer outages per year, which combines the unit business interruption cost per customer class and the estimated number of affected natural gas customers with estimated probabilities of UGS disruptions. All models and analyses are based on publicly available data. The report presents a set of findings and recommendations in terms of data, further analyses, regulatory requirements and standards, and needs to improve gas/electric industry coordination for electric reliability.

    Interest in Natural Gas in Brazil emerged in the second half of the twentieth century, against a background in which the global giants of the petroleum and gas industries stated that reserves within the country were not commercially viable. This scenario changed with the discovery of numerous oil and gas fields and resulted in the participation of numerous foreign companies bidding for exploration and production rights in the new fields established by ANP. Natural Gas has come to assume a new dimension with further recent discoveries in Santos, Espirito Santo, Sergipe and Urucu, with proven reserves in the order of 490 billion m3. This new dimension is reinforced by PETROBRAS's current strategic plan which considers investments in the order of 3.5 Billion U$ dollars for the production, processing and transport of Natural Gas and half a billion dollars for thermoelectric power stations. The use of Natural Gas in industries, in general, and in the generation of electricity will provide a strong push for the country's economy, substituting other sources of energy with the recognized advantages for production and reduced environmental impact. In this new era 24 gas distribution companies, widely distributed throughout Brazil, are also programming new investments to make best the use of Natural Gas for industry, commerce, for the residential sector and throughout all the national territory.

    Indonesia depends heavily on revenues from the export of LNG and oil, the availability of which appears to be decreasing. It is therefore making a strong effort to accelerate development of a domestic natural gas industry. A high priority has been given to the conversion of power plants and city gas systems, including local industries and commercial facilities, from liquid fuels to natural gas. This will release more oil for export, help to meet the objectives of Repelita V, and provide substantial environmental benefits. The World Bank recently provided loans to the Indonesian Government for two projects that are aimed at substituting natural gas for oil and manufactured gas in domestic markets. One project involves expansion of the gas distribution systems of Indonesia's natural gas utility (PGN) in three cities: Jakarta and Bogor in Java, and Medan in Sumatra. Approximately 350 new industrial, 800 new commercial, and 12,700 new residential natural gas customers are expected from this project. Incremental gas sales are projected to be about 48.1 million CF/d when the project is completed in 1992. The project also includes training programs for PGN staff and an energy pricing policy study to be carried out by Indonesia's Ministry of Mines and Energy. The second project involves expansion of the supply of natural gas for Surabaya and twelve other towns in its vicinity in East Java, and further expansion of Medan's supply system. The gas for Surabaya will be used for about 400 industrial and 150 commercial customers, and 3,600 households. The additional gas supply for Medan will be used for two power plants operated by the state electric utility, PLN. Incremental natural gas sales from this project are projected to be 68 million CF/d when it is

    Indonesia imports high amount of Fuel Oil. Although Indonesia has abundant amount of natural gas reserve, the obstacle lies within the process of natural gas storage itself. In order to create a safe repository, the ANG (Adsorbed Natural Gas) technology is planned. ANG technology in itself has been researched much to manufacture PET-based activated carbon for natural gas storage, but ANG still has several drawbacks. This study begins with making preparations for the equipment and materials that will be used, by characterizing the natural gas, measuring the empty volume, and degassing. The next step will be to examine the adsorption process. The maximum storage capacity obtained in this study for a temperature of 27°C and pressure of 35 bar is 0.0586 kg/kg, while for the desorption process, a maximum value for desorption efficiency was obtained on 35°C temperature with a value of 73.39%.

    1993-01-01

    Recent dramatic changes in natural gas markets have significant implications for the scope and direction of DOE's upstream as well as downstream natural gas R ampersand D. Open access transportation changes the way gas is bought and sold. The end of the gas deliverability surplus requires increased reserve development above recent levels. Increased gas demand for power generation and other new uses changes the overall demand picture in terms of volumes, locations and seasonality. DOE's Natural Gas Strategic Plan requires that its R ampersand D activities be evaluated for their ability to provide adequate supplies of reasonably priced gas. Potential R ampersand D projects are to be evaluated using a full fuel cycle, benefit-cost approach to estimate likely market impact as well as technical success. To assure R ampersand D projects are evaluated on a comparable basis, METC has undertaken the development of a comprehensive natural gas technology evaluation framework. Existing energy systems models lack the level of detail required to estimate the impact of specific upstream natural gas technologies across the known range of geological settings and likely market conditions. Gas Systems Analysis Model (GSAM) research during FY 1993 developed and implemented this comprehensive, consistent natural gas system evaluation framework. Rather than a isolated research activity, however, GSAM represents the integration of many prior and ongoing natural gas research efforts. When complete, it will incorporate the most current resource base description, reservoir modeling, technology characterization and other geologic and engineering aspects developed through recent METC and industry gas R ampersand D programs

    Since biogas and natural gas basically have the same characteristics, they can be distributed in the same system. In the parts of the country where there is an extensive natural gas distribution network, the infrastructure for natural gas can be used for distribution of biogas. In order to increase the use of renewable energy, it is a political ambition to increase the share of biogas in the natural gas network, and, in the long run, entirely replace natural gas with biogas. Much of biogas production in the country is, however, not reached by the existing natural gas network, and this is also the case for a large part of the potential for future biogas production. In these areas the gas is transported in more or less extensive local gas distribution networks and by truck in compressed or liquid form. Transport of compressed and liquefied gas is efficient in some cases and development of these systems is an ongoing process. A number of facilities are planned for production of large quantities of biogas, several hundred GWh/year, through digestion and gasification processes. These plants will be located either in conjunction with major gas consumers or in the vicinity of the existing natural gas grid. The potential for biogas production is, however, present throughout the country and in order to meet market demand biogas requires efficient distribution systems

    Natural gas is the major indigenous source of energy in Bangladesh and accounts for almost one-half of all primary energy used in the country. Per capita and total energy use in Bangladesh is still very small, and it is important to understand how energy, and natural gas demand will evolve in the future. We develop a dynamic econometric model to understand the natural gas demand in Bangladesh, both in the national level, and also for a few sub-sectors. Our demand model shows large long run income elasticity - around 1.5 - for aggregate demand for natural gas. Forecasts into the future also show a larger demand in the future than predicted by various national and multilateral organizations. Even then, it is possible that our forecasts could still be at the lower end of the future energy demand. Price response was statistically not different from zero, indicating that prices are possibly too low and that there is a large suppressed demand for natural gas in the country. - Highlights: → Natural gas demand is modeled using dynamic econometric methods, first of its kind in Bangladesh. → Income elasticity for aggregate natural gas demand in Bangladesh is large-around 1.5. → Demand is price insensitive, indicating too low prices and/or presence of large suppressed demand. → Demand forecasts reveal large divergence from previous estimates, which is important for planning. → Attempts to model demand for end-use sectors were successful only for the industrial sector.

    The impact of rising natural gas prices on the United States economy and domestic industries was examined in this PowerPoint presentation. Industry comments were solicited on the effects of natural gas prices on their business performance from 2000 to 2004 in order to collect data, and macroeconomic impacts were determined through the use of an inter-industry model. Results of the survey and subsequent model suggested that in 2000 and 2001, real gross domestic product (GDP) growth was depressed by 0.2 per cent because of higher natural gas prices. Between 2000 and 2004, the civilian workforce was lower by 489,000 jobs. It was determined that nitrogenous fertilizer manufacturing was the most gas intensive industry. The results indicated that higher natural gas prices were an additional burden on manufacturing industries, and that the economic performance of natural gas intensive industries was poor between 2000-2004. However, it was just as poor between 1997-2000, when gas prices were relatively low and stable. Natural gas intensive industries passed along price increases in their products to their downstream consumers. Despite job losses, wages in natural gas intensive industries were higher and grew faster than in the rest of the manufacturing industry in the 2000-2004 period. Although capital expenditures declined between 2000 to 2004, they declined more rapidly in the 1997-2000 period. There has been no evidence of a decline in international competitiveness of natural gas intensive industries. It was concluded that rising natural gas prices have had a significant impact on the growth of the economy and workforce. tabs., figs

  3. Why natural gas for CO2 and climate control?

    International Nuclear Information System (INIS)

    Roose, T.R.

    1996-01-01

    The Intergovernmental Panel on Climate Change (IPCC) and the US Environmental Protection Agency (EPA) have suggested that increased use of natural gas is a possible strategy for reducing the potential for global warming. Carbon dioxide (CO 2 ) contributes as much to global warming as all other greenhouse gases combined. During combustion, natural gas generates less CO 2 per unit of energy produced than either coal or oil. On the basis of the amount of CO 2 emitted, the potential for global warming could be reduced by substituting natural gas to coal or oil. However, since natural gas is primarily methane, a potent greenhouse gas, these emissions could reduce natural gas's inherent advantage of lower CO 2 emissions. To address this issue and compare the fuels on an equivalent basis, it is necessary to account for emissions of all greenhouse gases throughout the fuel cycle of each fuel and to determine the impact of these gases on global warming. Gas Research Institute and EPA jointly funded a study to quantify methane emissions from the natural gas industry so that this information could be used as input to address the issue of the fuel switching strategy. The study found that the natural gas industry emitted 1.4% of natural gas production (314 Bscf of methane) to the atmosphere in 1992. Today, due to voluntary reductions from the gas industry, the percent leaked is even less. This 1992 amount has been analyzed over a broad range of global warming potentials, and the conclusion that fuel switching to natural gas reduces the potential for global warming is supported. The results of this study are presented in this paper

  4. TREATMENT OF NATURAL GAS BY ADSORPTION OF CO2

    2015-12-01

    Full Text Available Apart from burning, one of the possible uses of natural gas is as a fuel for motor vehicles. There are two types of fuel from natural gas — CNG (Compressed Natural Gas or LNG (Liquefied Natural Gas. Liquefaction of natural gas is carried out for transport by tankers, which are an alternative to long-distance gas pipelines, as well as for transport over short distance, using LNG as a fuel for motor vehicles. A gas adjustment is necessary to get LNG. As an important part of the necessary adjustment of natural gas to get LNG, a reduction of CO2 is needed. There is a danger of the carbon dioxide freezing during the gas cooling. This work deals with the testing of adsorption removal of CO2 from natural gas. The aim of these measurements was to find a suitable adsorbent for CO2 removal from natural gas. Two different types of adsorbents were tested: activated carbon and molecular sieve. The adsorption properties of the selected adsorbents were tested and compared. The breakthrough curves for CO2 for both adsorbents were measured. The conditions of the testing were estimated according to conditions at a gas regulation station — 4.0MPa pressure and 8 °C temperature. Natural gas was simulated by model gas mixture during the tests. The breakthrough volume was set as the gas volume passing through the adsorber up to the CO2 concentration of 300 ml/m3 in the exhaust gas. The thermal and pressure desorption of CO2 from saturated adsorbents were also tested after the adsorption.

    2007-01-01

    Geologically estimated natural gas resources are 500 Tcm. With the advance in geological science increase of estimated resources is expected. Natural gas reserves in 2000 have been proved to be around 165 Tcm. As it is known the reserves are subject to two constraints, namely: capital invested in the exploration and drilling technologies used to discover new reserves. The natural gas scarcity factor, i.e. ratio between available reserves and natural gas consumption, is around 300 years for the last 50 years. The new discovery of natural gas reserves has given rise to a new energy strategy based on natural gas. Natural gas utilization is constantly increasing in the last 50 years. With new technologies for deep drilling, we have come to know that there are enormous gas resources available at relatively low price. These new discoveries together with high demand for the environment saving have introduced a new energy strategy on the world scale. This paper presents an evaluation of the potential natural gas utilization in energy sector. As the criteria in this analysis resource, economic, environmental, social and technological indicators are used. Among the potential options of gas utilization following systems are considered: Gas turbine power plant, combine cycle plant, CHP power plant, steam turbine gas-fired power plant, fuel cells power plant. Multi-criteria method was used for the assessment of potential options with priority given to the Resource, Economic and Social Indicators. Results obtained are presented in graphical form representing priority list of potential options under specific constraints in the priority of natural gas utilization strategy in energy sector

  6. Comparative economics of natural gas vehicles and other vehicles

    Biederman, R.T.; Blazek, C.F.

    1992-01-01

    The utilization of alternative fuels for transportation applications is now a certainty. The only real questions that remain to be answered involve the type of fuel (or fuels) to be adopted most extensively. While some alternative fuel advocates suggest that a niche will exist for all alternative fuels, the most likely scenario will involve widespread use of only a few major fuel types. Undoubtedly, reformulated gasoline will be a major force as an interim fuel, due to inertia and a predominant bias toward liquid fuels. The prospects for utilization of ethanol, methanol, MTBE, and ETBE appear to be most promising in the area of blending with gasoline to meet the needs of reformulated gasoline and flexible fueled vehicles (FFV's). Propane fueled vehicles will continue to grow in popularity, especially with fleets, but will never become a major force in the transportation market in the U.S. due to unresolvable supply limitations. The clear winner in the alternative fuels transportation market appears to be natural gas. Either in compressed or liquefied form, natural gas enjoys low costs, tremendous availability, and impressive environmental benefits. As shown in this analysis, natural gas competes favorably with gasoline in terms of economics. Natural gas is also preferential to other alternative fuels in terms of safety and heath issues as well as operational issues. Adoption of natural gas as a standard transportation fuel will probably require market segmentation characterized by compressed natural gas utilization in light-duty vehicles and liquefied natural gas utilization in heavy-duty vehicles. The most significant barrier to natural gas utilization will continue to be the creation of a refueling infrastructure. As these problems are resolved, however, natural gas will emerge as the transportation fuel of the future

  7. The contribution of the DOE's R ampersand D budget in natural gas to energy price security

    International Nuclear Information System (INIS)

    Sutherland, R.J.

    1992-01-01

    The energy price volatility model suggests that some of the proposed natural gas programs can contribute to energy price stability. The sector most vulnerable to fuel price variations is, of course, the transportation sector. The most effective strategy to achieve energy pace stability is to reduce petroleum consumption in this sector. The natural gas vehicle program is therefore recommended as potentially important and worthy of further consideration. At this point, distinguishing the merits of various subprograms is not feasible. This result farther supports the conclusion that the DOE's energy R ampersand D portfolio is not efficiently balanced and an increase in oil and gas research should be a high priority. The DOE has responded favorably and has significantly increased its proposed research with the explicit objective of displacing oil in the transportation sector. The enhanced research and development program for energy security, in the NES, proposes major funding, increases in this area. To recommend the further increases proposed by the industry, a careful analysis of incremental benefits and costs is required. The proposed natural as supply program is intended to enhance the future supply of natural gas. As explained above, enhanced gas supplies can reduce the volatility of gas prices and severe the link between gas and oil prices. The gas supply program is recommended as a potentially important strategy to ensure energy price stability. The importance of this point merits restatement. Oil price volatility affects directly the transportation and industrial sectors. The residential, commercial and electric utility sectors are not highly oil dependent. However, oil prices have affected gas prices and gas is used extensively the residential, commercial, industrial and electric utility sectors. Energy price stability is enhanced in these sectors by severing, the link, between oil and gas prices

    A selective and economical route for converting natural gas to olefins is described: the GTO process. The first step in the process is natural gas conversion to methanol, followed by the UOP/Hydro MTO (methanol to olefins) process using UOP`s unique SAPO-34 catalyst. The primary products are ethylene and propylene. The GTO UOP/Hydro MTO process has favorable economics in areas where low-cost natural gas is available and easily beats the internal rates of return from traditional naphtha cracking in these locations. 19 refs.

    Europe's Common Market offers an interesting challenge to its member countries' natural gas distribution system operators in that which regards the creation of a European-wide natural gas control board, and European standardization and regulatory committees contemporaneously guaranteeing a free market for suppliers, as well as, consumer protection. Relative legislation and normatives activities will be deemed the responsibility of the European administrative structure and the the European Normatives Committee respectively. This paper briefly illustrates the progress that has been accomplished thus far in the standardization of technical aspects. Focus is on the certification of natural gas distribution system constructors

    In the last years, natural gas has become an important energy source in underglaze horticulture of the Federal Republic of Germany. Special techniques for application such as CO{sub 2}-concentration from waste gases of gas boilers and the application of CO{sub 2} - common also for the heating of vegetable cultures can be realized technically and economically advantageous with natural gas. New technologies such as cogeneration plants with gas engine for plant lighting are technically perfected in the meantime. As a whole, the application of natural gas facilitates a good efficiency and thus, a very good utilization of fuel. (orig./BWI).

    Industrial development based on natural gas has broad, industrial implications. Norway has a vital industry based on natural gas as raw material, here under Ormen Lange, Snoehvit LNG, Tjeldbergodden and Petrochemical Grenland. The petrochemical industry has challenges, e.g. the cost of raw materials and energy, localization related to the markets, and recruitment, but considerable investments are made in the sector. The Northern areas in Norway may have special challenges related to bringing the product to the market. Solutions to this challenge are in LNG (liquid natural gas), GTL (gas to liquids), and GTO (gas to olefins)

    In a generally stagnant energy market, gas will be the energy with the highest growth rate in Germany, especially because of its steadily rising shares in the residential and commercial sector. In western Germany there is to be accepted that the demand forecasts, which were raised from one conference to the next, have passed their zenith. Great uncertainty exists as regards the future use of gas for power generation. In the absence of any significant expansion of this market sector, which is considered rather improbable in western Germany, it can be stated that anticipated gas demand up to the year 2005 is already covered by existing import contracts and scheduled domestic production. The picture is completely different in eastern Germany, where a doubling of consumption is quite feasible. To achieve the requisite diversification of supplies, substantial additional imports from western sources will have to be contracted. Russia can and should remain eastern Germany's main supplier in the long run, but Russian deliveries must be placed on a reliable, long-term contractual basis. As far as new gas projects are concerned, deliveries from Norway, to a limited extent from the United Kingdom and above all as part of the new Russian export initiative are under discussion. Generally speaking, transit will be an increasingly significant issue, especially for additional supplies from Russia. The efficiency and reliability of gas marketing companies will become far more important in an environment characterised by growing uncertainties. The reliable customer offering a dependable market outlet will be increasingly sought. With energy prices likely to increase only slightly, the management of uncertainties and the safeguarding of economic driving forces will be the main challenge facing our supply projects. 15 figs

  15. The voice of Canada's oil and natural gas industry : oil and natural gas

    International Nuclear Information System (INIS)

    2001-04-01

    The Canadian Association of Petroleum Producers (CAPP) represents 150 members of the oil and gas industry, which together are responsible for approximately 95 per cent of the oil and natural gas produced in Canada. The upstream sector comprises companies that explore for, develop and produce petroleum resources, while the downstream sector involves companies that refine and market the resources. CAPP works closely with governments of 11 of Canada's 13 provinces and territories and with public groups to represent upstream producers active across the country. The enhancement of the economic well-being and sustainability of the upstream petroleum industry is the mission of the CAPP. The main priorities of the CAPP are: Environment, Health and Safety Stewardship, reasonable and timely access to resources, competitiveness of the Canadian industry on a global basis, the secure and efficient access to markets, and open and constructive public, government and media affairs. Some of the issues dealt with by the CAPP are sour gas, flaring, venting and industry-landowner relations, improved safety performance, federal issues such as corporate taxes and environmental issues, Aboriginal and First Nations issues, transportation costs for natural gas on major pipelines, and oil and sands bitumen issues, to name a few. The board of the CAPP is made up of 32 members. The work is carried out by hundreds of volunteers from member companies who provide their time and expertise for various committees and working groups, as well as a staff of approximately 40 people to assist them. The members provide the entire funding for CAPP, which is located in Calgary, Alberta. The document concluded with a few facts concerning the petroleum industry in general. 12 figs

  16. Natural gas in the Asian Pacific region: market behavior and the Japanese electricity market

    2001-04-01

    This dissertation consists of four main chapters, all related to the Asian Pacific natural gas market, and the role of the Japanese electricity sector. The natural gas market in Asia Pacific is heavily dependent on the demand from Japan, which imports around 75% of the gas traded as LNG (liquefied natural gas) in the region. The demand for natural gas in Japan is, in turn, almost exclusively driven by the electricity industry that consumes around 70 % of the imported natural gas. On the supply side we find seller concentrations with only six countries exporting LNG in the region. The first main chapter analyzes the market structure of the Asian Pacific natural gas market, the next two relate to the usage of natural gas in the Japanese fossil-fueled electricity production, and the final study investigates the demand for electricity in the residential sector in Japan. The first chapter argues that the buyers in Japan, through cooperation, have the potential to exert the market power that their large market share provides them with. This could be offset by the monopoly power that the six present sellers have. In the chapter four, the solutions for the four imperfect competition cases of, monoposony, monopoly, bilateral monopoly, and the Cournot model are simulated. Neither of the model solutions comes close to both the actual market price, and the actual gas volumes. The model that best mimics the actual price is the bilateral monopoly model, while the monoposony model comes closest to the actual volumes. Giving some mixed evidence of how the Asian LNG market works. Given the indication of market power, the second study analyzes the fossil-fuel mix efficiency in the power sector in Japan. If the power sector is able to exert the alleged market power, it may be the case that they minimize costs according to shadow prices instead of actual market prices. Such behavior could cause the fossil-fuel mix used for power generation to be inefficient. The analysis is based on a

    Natural gas has the potential to increase the biofuel production output by combining gas- and biomass-to-liquids (GBTL) processes followed by naphtha and diesel fuel synthesis via Fischer-Tropsch (FT). This study reflects on the use of commercial-ready configurations of GBTL technologies and the environmental impact of enhancing biofuels with natural gas. The autothermal and steam-methane reforming processes for natural gas conversion and the gasification of biomass for FT fuel synthesis are modeled to estimate system well-to-wheel emissions and compare them to limits established by U.S. renewable fuel mandates. We show that natural gas can enhance FT biofuel production by reducing the need for water-gas shift (WGS) of biomass-derived syngas to achieve appropriate H2/CO ratios. Specifically, fuel yields are increased from less than 60 gallons per ton to over 100 gallons per ton with increasing natural gas input. However, GBTL facilities would need to limit natural gas use to less than 19.1% on a LHV energy basis (7.83 wt %) to avoid exceeding the emissions limits established by the Renewable Fuels Standard (RFS2) for clean, advanced biofuels. This effectively constitutes a blending limit that constrains the use of natural gas for enhancing the biomass-to-liquids (BTL) process.

    This paper describes the investigation on residual swirl flow in a 120 MW natural gas, full-scale, tangential-fired boiler. Emphasis is given towards the understanding of the behavior of the combustion gas flow pattern and temperature distribution as a result of the tangential firing system of the boiler. The analysis was carried out based on three-dimensional computational modeling on full scale boiler with validation from key design parameter as well as practical observation. Actual operating parameters of the actual boiler are taken as the boundary conditions for this modeling. The prediction of total heat flux was found to be in agreement with the key design parameter while the residual swirl predicted at the upper furnace agrees qualitatively with the practical observation. Based on this comparison, detail analysis was carried out for comprehensive understanding on the generation and destruction of the residual swirl behavior in boiler especially those with high capacity.

  19. Research and Development Concerning Coalbed Natural Gas

    The Powder River Basin in northeastern Wyoming is one of the most active areas of coalbed natural gas (CBNG) development in the western United States. This resource provides clean energy but raises environmental concerns. Primary among these is the disposal of water that is co-produced with the gas during depressurization of the coal seam. Beginning with a few producing wells in Wyoming's Powder River Basin (PRB) in 1987, CBNG well numbers in this area increased to over 13,600 in 2004, with projected growth to 20,900 producing wells in the PRB by 2010. CBNG development is continuing apace since 2004, and CBNG is now being produced or evaluated in four other Wyoming coal basins in addition to the PRB, with roughly 3500-4000 new CBNG wells permitted statewide each year since 2004. This is clearly a very valuable source of clean fuel for the nation, and for Wyoming the economic benefits are substantial. For instance, in 2003 alone the total value of Wyoming CBNG production was about $1.5 billion, with tax and royalty income of about $90 million to counties, $140 million to the state, and $27 million to the federal government. In Wyoming, cumulative CBNG water production from 1987 through December 2004 was just over 380,000 acre-feet (2.9 billion barrels), while producing almost 1.5 trillion cubic feet (tcf) of CBNG gas statewide. Annual Wyoming CBNG water production in 2003 was 74,457 acre-feet (577 million barrels). Total production of CBNG water across all Wyoming coal fields could total roughly 7 million acre-feet (55.5 billion barrels), if all of the recoverable CBNG in the projected reserves of 31.7 tcf were produced over the coming decades. Pumping water from coals to produce CBNG has been designated a beneficial water use by the Wyoming State Engineer's Office (SEO), though recently the SEO has limited this beneficial use designation by requiring a certain gas/water production ratio. In the eastern part of the PRB where CBNG water is generally of good

    For the last fifteen years, the natural gas price forecasting experts have had a terrible record of forecasting future natural gas prices. (In the early 80's, the gas price was forecasted to be over $10/MMBtu in the late 80's). To make matters even worse, they can't seem to understand why the price is what it is, even in hindsight. If these experts can't even get it right in hindsight, how can one ever expect to get it right in foresight? It is concluded that the traditional laws of supply and demand don't work very well in this new quasi-regulated natural gas industry. Evidently, Social Influences and Political Influences are more important than the Economic Influence on natural gas prices

    Today, the globalisation of natural gas markets is a topic much discussed amongst gas industry practitioners, policy makers and academics. If there is a consensus on a tendency towards the ''commoditisation'' of natural gas markets, there is less agreement on the certainty of the global approach to gas marketing. The aim of this paper is to untangle the main drivers behind the globalisation of natural gas markets, both on the demand and supply sides, and to discuss problems related to the market structure, such as price arbitrages and organised markets. The paper will conclude that the globalisation of natural gas markets cannot be approached as a deterministic problem and as a consequence, there is still no precise answer as to when the different regional gas markets will forge a global one.

    This paper is an up-to-date, but only moderately technical survey, of the natural gas market. Supply, demand and pricing are discussed, and, in the light of the electricity deregulation experiment in California, where the expression ''dangerous failure'' has been repeatedly used to describe the extensive losses suffered by final consumers and utilities (or retailers), a modicum of attention is paid to the prospects for deregulating natural gas. Some microeconomics of the natural gas market is presented at a more elementary level than in author's energy economics textbook (2000) or book ''The Political Economy of Natural Gas'' (1987), and the author makes a studied attempt to avoid bringing the misleading Hotelling model (of exhaustible resource depletion) into the exposition. Finally, some comments on risk management with futures contracts are provided, and there is a brief mathematical appendix on futures, options and two-part pricing. (author)

    1995-12-31

    The U.S. Environmental Protection Agency (EPA) and the Gas Research Institute (GRI) cofunded a project to quantify methane (CH{sub 4}) emissions from the U.S. natural gas industry. Methane, the major constituent of natural gas, is a potent greenhouse gas that is believed to increase the effect of global warming when released to the atmosphere. Reducing emissions from natural gas systems would lessen the greenhouse gas effect attributable to atmospheric CH{sub 4}. Further, mitigation methods to reduce emissions of natural gas, a marketable resource, could save money and increase energy efficiency. This presentation summarizes the major sources and quantity of methane being emitted to the atmosphere for all segments of the U.S. gas industry: production; processing; storage; transmission; and distribution. A description of how those emissions were determined is included here, as well as a discussion of which sources are potential candidates for reducing emissions. (author)

    For the Dutch government, natural gas is an important source of revenue. The liberalisation of the gas market has serious consequences for the revenues the Dutch government generates by producing and selling natural gas. In late September 1999, the Netherlands Office of Audits ('Algemene Rekenkamer') published a report with gloomy prospects concerning future natural gas revenues. The Office expects a reduction in government revenues that may even run into more than 2 billion Dutch guilders a year. A report was prepared to provide insight into the financial effects of market liberalisation and to allow the Dutch Parliament to reach an informed decision

  11. Operation and planning of coordinated natural gas and electricity infrastructures

    Science.gov (United States)

    Zhang, Xiaping

    Natural gas is becoming rapidly the optimal choice for fueling new generating units in electric power system driven by abundant natural gas supplies and environmental regulations that are expected to cause coal-fired generation retirements. The growing reliance on natural gas as a dominant fuel for electricity generation throughout North America has brought the interaction between the natural gas and power grids into sharp focus. The primary concern and motivation of this research is to address the emerging interdependency issues faced by the electric power and natural gas industry. This thesis provides a comprehensive analysis of the interactions between the two systems regarding the short-term operation and long-term infrastructure planning. Natural gas and renewable energy appear complementary in many respects regarding fuel price and availability, environmental impact, resource distribution and dispatchability. In addition, demand response has also held the promise of making a significant contribution to enhance system operations by providing incentives to customers for a more flat load profile. We investigated the coordination between natural gas-fired generation and prevailing nontraditional resources including renewable energy, demand response so as to provide economical options for optimizing the short-term scheduling with the intense natural gas delivery constraints. As the amount and dispatch of gas-fired generation increases, the long-term interdependency issue is whether there is adequate pipeline capacity to provide sufficient gas to natural gas-fired generation during the entire planning horizon while it is widely used outside the power sector. This thesis developed a co-optimization planning model by incorporating the natural gas transportation system into the multi-year resource and transmission system planning problem. This consideration would provide a more comprehensive decision for the investment and accurate assessment for system adequacy and

    Climate change, global warming, urban air pollution, energy supply uncertainty and depletion, and rising costs of conventional energy sources are, among others, potential socioeconomic threats that our community faces today. Transportation is one of the primary sectors contributing to oil consumption and global warming, and natural gas (NG) is considered to be a relatively clean transportation fuel that can significantly improve local air quality, reduce greenhouse-gas emissions, and decrease the energy dependency on oil sources. Internal combustion engines (ignited or compression) require only slight modifications for use with natural gas; rather, the main problem is the relatively short driving distance of natural-gas-powered vehicles due to the lack of an appropriate storage method for the gas, which has a low energy density. The U.S. Department of Energy (DOE) has set some targets for NG storage capacity to obtain a reasonable driving range in automotive applications, ruling out the option of storing methane at cryogenic temperatures. In recent years, both academia and industry have foreseen the storage of natural gas by adsorption (ANG) in porous materials, at relatively low pressures and ambient temperatures, as a solution to this difficult problem. This review presents recent developments in the search for novel porous materials with high methane storage capacities. Within this scenario, both carbon-based materials and metal-organic frameworks are considered to be the most promising materials for natural gas storage, as they exhibit properties such as large surface areas and micropore volumes, that favor a high adsorption capacity for natural gas. Recent advancements, technological issues, advantages, and drawbacks involved in natural gas storage in these two classes of materials are also summarized. Further, an overview of the recent developments and technical challenges in storing natural gas as hydrates in wetted porous carbon materials is also included

    Emission improvement in both city centers and conurbations is an important factor which developers of public-utility vehicles and buses must take into account. If natural gas is used as a fuel the emission is considerably lower than that from conventional diesel drive. Thus it is an important contribution to keep the air clean in the area where the vehicles are deployed. In this paper the project 'Ecological Natural gas drive for city buses in Skopje' is analysed.

  20. Natural gas - bridge to a clean energy future

    International Nuclear Information System (INIS)

    Doelman, J.

    1991-01-01

    Per unit of useful energy natural gas gives the lowest environmental pollution of all fossil fuels. This is due to its low carbon content, the absence of sulphur compounds, and the fact that natural gas can, rather easily, be burnt completely in such a way that also the NO x emission is acceptably low. Although natural gas has already a good record as an efficient and clean fuel large improvements are still possible, but this requires more R+D and time. The presently known natural gas world reserves are high enough to go for a substantially higher share of gas in the energy package. E.g. replacing coal by natural gas will give large environmental improvements. Furthermore, direct gas use is very often the most efficient and cleanest option, also when electricity is an alternative. To develop and connect the known large reserves to the market enormous amounts of money are required. The political and economical situation should make these investments possible and attractive. The ideas first expressed by the Dutch prime minister, now incorporated in the Energy Charter, have been developed to that end. Special attention should be given to the development of small gas fields as is e.g. being done in The Netherlands, which has improved the local gas reserves situation impressively. As a first major step to a clean future the potential of natural gas should be explored and put to work worldwide. Its potential as an important diversified source of energy is underestimated. Amongst others by funding more natural gas R+D natural gas should develop a keyrole in the energy scene of the next 3-5 decades.(author) 3 figs., 8 tabs., 3 refs

    Studies have shown that the demand for crude oil exceeds supply and other energy sources are needed to met the shortfall. Natural gas and coal are the only 2 current energy sources that have the global capacity to, by themselves, address increased energy demand in a timely manner. Both these resources have been used primarily for power generation and heating. This paper discussed the transition that will likely occur in which natural gas and coal will be used increasingly as transportation fuels. It presented data comparing the environmental impact of using methane versus coal and proposed natural gas as the future green fuel. A strengths, weaknesses, opportunities and threats (SWOT) analysis was conducted to obtain a better understanding of the current Canadian natural gas market. The strengths include recent discoveries in the Horn River Basin and the Montney plays in British Columbia which are expected to triple natural gas production within the next decade. The weaknesses include an oversupply of gas compared to current demand; gas prices are currently in a range that are barely economic for many shale plays; and Canadian gas is disadvantaged for sales in the United States by additional pipeline transportation costs. The opportunities include global export opportunities of liquefied natural gas (LNG) through the proposed Kitimat LNG export facility and others off the west coast of Canada. The threat facing natural gas development is the strong competition for market share with coal. However, emissions data and energy efficiencies provide evidence to support the choice to use natural gas. 5 refs., 2 tabs., 26 figs.

  5. Experimental Study of Natural Gas Temperature Effects on the Flame Luminosity and No Emission

    2012-06-01

    Full Text Available The flame radiation enhancement in gas-fired furnaces significantly improves the thermal efficiency without significantly affecting the NOx emissions. In this paper, the effects of inlet natural gas preheating on the flame luminosity, overall boiler efficiency, and NO emission in a 120 kW boiler have been investigated experimentally. Flame radiation is measured by use of laboratory pyranometer with photovoltaic sensor. A Testo350XL gas analyzer is also used for measuring the temperature and combustion species. The fuel is preheated from the room temperature to 350°C. The experimental measurements show that the preheating of natural gas up to about 240°C has no considerable effect on the flame luminosity. The results show that increasing the inlet gas temperature from 240°C, abruptly increases the flame luminosity. This luminosity increase enhances the boiler efficiency and also causes significant reduction in flame temperature and NO emission. The results show that increasing the inlet gas temperature from 240°C to 300°C increases the flame luminous radiation by 60% and boiler efficiency by 20%; while the maximum flame temperature and the boiler NO emission show a 10% and 8% decrease respectively.

    The use of decline curve analysis to analyse and extrapolate the production performance of oil and gas reservoirs was discussed. This mathematical analytical tool has been a valid method for estimating the conventional crude oil resources of the Western Canada Sedimentary Basin (WCSB). However, it has failed to provide a generally acceptable estimate of the conventional natural gas resources of the WCSB. This paper proposes solutions to this problem and provides an estimate of the conventional natural gas resources of the basin by statistical analysis of the declining finding rates. Although in the past, decline curve analysis did not reflect the declining finding rates of natural gas in the WCSB, the basin is now sufficiently developed that estimates of conventional natural gas resources can be made by this analytical tool. However, the analysis must take into account the acceleration of natural gas development drilling that has occurred over the lifetime of the basin. It was concluded that ultimate resources of conventional marketable natural gas of the WCSB estimated by decline analysis amount to 230 tcf. It was suggested that further research be done to explain why the Canadian Gas Potential Committee (CGPC) estimate for Alberta differs from the decline curve analysis method. 6 refs., 35 figs

    2001-09-01

    The Canadian Gas Association (CGA) is the industry organization that represents the Canadian natural gas and energy delivery industry. It is on the frontline of consumer perceptions regarding natural gas, which is the fuel of choice for Canadian homeowners. Canadian consumers have benefitted from the deregulation initiatives of the mid-1980s which provided significant growth opportunities. Given the tumultuous energy environment throughout North America, the CGA believes that a national energy strategy should be developed to address future supply issues and also to examine ways to ensure that extreme market shifts are anticipated and mitigated as much as possible. The CGA is ready to provide governments with input for such a strategy representing the perspective of the Canadian consumer. The CGA recommends that the Government of Canada, the provinces and territories adopt the following initiatives regarding the use of natural gas: (1) recognize and promote the environmental qualities and applications of natural gas, (2) encourage competition, (3) promote transparent and consistent approach to regulation, (4) reaffirm commitment to market-based policies, (5) facilitate economic research, analysis and communication about trends in the natural gas market, and (6) promote the development of new technologies that expand the uses of natural gas and support research in infrastructure development. The government's actions in the areas proposed in this report will contribute to advancing Canada's environmental objectives and economic growth. 2 figs

  8. Natural gas is more than gas power plants

    Through the Statpipe gas line at Karmoey, Norway supplies 20% of the natural gas on the European market. The pipeline is 'leaking' a little bit of gas to the local communities at Karmoey and Haugesund. These communities have replaced 65% of their oil consumption with natural gas, which is a fine contribution to a better environment. The supplier of the natural gas, Gasnor ASA in this case, claims an energy efficiency of 90% at the end user because the gas burns directly and the loss in the pipeline is minimal. The efficiency of natural gas utilisation is twice that of the planned gas power stations in West-Norway, subtracting the losses in the electrical network. Gasnor ASA competes with oil suppliers and, if necessary, with electric utilities. The county hospital at Haugesund is quoted as an example. The hospital has two large boilers with dual fuel burners. They have been using natural gas since 1998 because it was worth while both economically and environmentally. The use of natural gas in the transport sector would be very important, but the necessary infrastructure is very little developed. For instance, five diesel-powered ferries on the Boknafjord emit as much NOx as the planned gas power plant at Kaarstoe

    Facing severe air pollution and growing dependence on natural gas imports, the Chinese government plans to increase coal-based synthetic natural gas (SNG) production. Although displacement of coal with SNG benefits air quality, it increases CO2 emissions. Due to variations in air pollutant and CO2 emission factors and energy efficiencies across sectors, coal replacement with SNG results in varying degrees of air quality benefits and climate penalties. We estimate air quality, human health, and climate impacts of SNG substitution strategies in 2020. Using all production of SNG in the residential sector results in an annual decrease of ˜32,000 (20,000 to 41,000) outdoor-air-pollution-associated premature deaths, with ranges determined by the low and high estimates of the health risks. If changes in indoor/household air pollution were also included, the decrease would be far larger. SNG deployment in the residential sector results in nearly 10 and 60 times greater reduction in premature mortality than if it is deployed in the industrial or power sectors, respectively. Due to inefficiencies in current household coal use, utilization of SNG in the residential sector results in only 20 to 30% of the carbon penalty compared with using it in the industrial or power sectors. Even if carbon capture and storage is used in SNG production with today’s technology, SNG emits 22 to 40% more CO2 than the same amount of conventional gas. Among the SNG deployment strategies we evaluate, allocating currently planned SNG to households provides the largest air quality and health benefits with the smallest carbon penalties.

    The current expansion of natural gas (NG) development in the United States requires an understanding of how this change will affect the natural gas industry, downstream consumers, and economic growth in order to promote effective planning and policy development. The impact of this expansion may propagate through the NG system and US economy via changes in manufacturing, electric power generation, transportation, commerce, and increased exports of liquefied natural gas. We conceptualize this problem as supply shock propagation that pushes the NG system and the economy away from its current state of infrastructure development and level of natural gas use. To illustrate this, the project developed two core modeling approaches. The first is an Agent-Based Modeling (ABM) approach which addresses shock propagation throughout the existing natural gas distribution system. The second approach uses a System Dynamics-based model to illustrate the feedback mechanisms related to finding new supplies of natural gas - notably shale gas - and how those mechanisms affect exploration investments in the natural gas market with respect to proven reserves. The ABM illustrates several stylized scenarios of large liquefied natural gas (LNG) exports from the U.S. The ABM preliminary results demonstrate that such scenario is likely to have substantial effects on NG prices and on pipeline capacity utilization. Our preliminary results indicate that the price of natural gas in the U.S. may rise by about 50% when the LNG exports represent 15% of the system-wide demand. The main findings of the System Dynamics model indicate that proven reserves for coalbed methane, conventional gas and now shale gas can be adequately modeled based on a combination of geologic, economic and technology-based variables. A base case scenario matches historical proven reserves data for these three types of natural gas. An environmental scenario, based on implementing a $50/tonne CO 2 tax results in less proven

    Conventional hydrogen production plants consist of natural gas steam reforming to CO+3H2 on Ni catalysts in a furnace, water-gas shift reaction for converting CO into CO2 and CO2 absorption. A new alternative method for highly endothermic steam reforming is autothermal reforming (steam reforming with air input to the reactor) without the need for external heating. In this study, hydrogen production by autothermal reforming for fuel cells (base case) was simulated based on a heterogeneous and ...

  13. Southwest British Columbia natural gas supply and deliverability: Discussion paper

    International Nuclear Information System (INIS)

    1994-02-01

    A review is presented of energy in British Columbia, the role of natural gas, and options available to enhance gas supply security in the province's most densely populated area, the southwest. British Columbia has abundant natural gas supplies, and production exceeds domestic demand. In 1992, natural gas supplied ca 25% of total provincial end-use energy requirements, but this share is expected to rise to 30% by 2015. Although some say that the province's natural gas production and transmission system should serve only domestic needs, this would have significant negative impacts. Domestic gas supply policy allows gas consumers to contract their own supplies, but contract security is required. Provincial guidelines allow demand-side programs to compete with supply sources to ensure that the resource profile is achieved at least cost. In the southwest, natural gas demand is projected to increase from 189 PJ in 1991 to 262 PJ by 2005. Most gas supplied to this region comes from northeast British Columbia through pipelines that are generally fully contracted. Short-term deliverability can be a problem, especially in peak winter demand periods. The gas industry's contingency plans for shortages are outlined and alternatives to enhance deliverability to the southwest are assessed, including storage, expansion of the pipeline system, supply curtailment, and peaking supply contracts. Aspects of provincial natural gas planning are discussed, including security of supply and deliverability, economic and environmental impacts, consumer costs, safety, and the public interest. A least-cost option for enhancing deliverability (underground storage and an additional liquefied natural gas plant) is estimated to cost consumers $3.69/GJ over 20 years. 9 figs., 1 tab

    Natural gas vehicles have been used in the world for many years: at present, there are about 3 million vehicles running on natural gas and many governments and vehicle manufactures are involved in programs for further developing the market for natural gas vehicles. In comparison to other forms of energy for vehicles, natural gas (NG) engenders low pressures on the environment. At the same time, because of its technical characteristics, NG is very suitable for motor use. The economic advantage of converting a vehicles (NGVs) would be expected to attract the interest of a great number of people, and achieve rapid and widespread diffusion. On the contrary, traditional fuels still dominate the scene, and show no sign of going out of fashion. The use of natural gas as automotive fuel has become of national and worldwide interests particularly so with the recent increase in petrol price, depleting petrol reserves and stringent control of exhaust emission levels. For automotive applications, shifting from petrol to gas needs technological research and development. Within the framework of the reciprocating piston based engine this development is very challenging with technological issues of low range, refueling infrastructure, heavy fuel storage, safety, emissions control and gas operating pressures. Other issues include available expertise and experience in research management. This paper describes the advances being made with passenger vehicles natural gas engines worldwide and in Malaysia more specific. The significant milestones in the development of NGV in Malaysia and the rationale behind the choice of NGV industry including the NGV vehicle population growth, the development of service station as well as the expansion of the sales volume will be illustrated. The presentation presents also development stages and advances in development, fabrication and testing a Compressed Natural Gas Direct Injection vehicle and NGV refueling station.

    North American and Canadian natural gas industry trends, such as supply, demand, storage, gas flows, prices and transportation capacities are summarized. The focus is on regional natural gas markets, as the issues of natural gas price differentials, gas market integration and the need for large expansions of natural gas pipeline capacity between markets will continue to hold center stage. Analysis of trends indicate that in 1997, the Canadian natural gas industry continued to be one of the two most important supply regions in North America although natural gas demand growth was weak (+0.3 per cent) due to a mild winter. Supply growth kept pace with poor demand growth. It was noted that over the next eight years, gas demand is expected to increase by an average annual rate of 2 per cent, down from the recent pace of 3 per cent annually. The sectors of the economy that are expected to lead the growth will be electricity generation and industrial use. The largest new demand will be seen in the U.S. Gulf Coast, Midwest, West, Northeast, and South Atlantic. Prices are expected to remain volatile but will not return to the low prices of 1995. Prices are expected to stay close to finding and development costs. The demand analysis provided much detail on the drivers of gas consumption by sector for each region in Canada and the United States. A regulatory analysis section was also included, given that recent regulatory events will have notable effects on natural gas markets. The National Energy Board and the U.S. Energy Information Administration were the main sources of statistical information, but private consultants, industry association and other federal government agencies in Canada and the U.S. also provided information. 19 refs., 12 tabs., 43 figs

    Natural gas is an important type of base-load energy, and its supply needs to be adjusted according to different demands in different seasons. For example, since natural gas is increasingly used to replace coal for winter heating, the demand for natural gas in winter is much higher than that in other seasons. As storage systems are the essential tools for balancing seasonal supply and demand, the design and simulation of natural gas storage systems form an important research direction. In this study, a large-scale underground storage system for natural gas is simulated based on theoretical analysis and finite element modeling.It is proven that the problem of axi-symmetric Darcy porous flow of ideal gas is governed by the Boussinesq equation. In terms of the exact solution to the Boussinesq equation, the basic operating characteristics of the underground storage system is analyzed, and it is demonstrated that the propagation distance of the pore pressure is proportional to the 1/4 power of the mass flow rate and to the 1/2 power of the propagation time. This quantitative relationship can be used to guide the overall design of natural gas underground storage systems.In order to fully capture the two-way coupling between pore pressure and elastic matrix deformation, a poro-elastic finite element model for natural gas storage is developed. Based on the numerical model, the dynamic processes of gas injection, storage and extraction are simulated, and the corresponding time-dependent surface deformations are obtained. The modeling results not only provide a theoretical basis for real-time monitoring for the operating status of the underground storage system through surface deformation measurements, but also demonstrate that a year-round balance can be achieved through periodic gas injection and extraction.This work is supported by the CAS "100 talents" Program and the National Natural Science Foundation of China (41371090).

    Radon and thoron concentrations in soil pores in a gas production region of the Anzoategui State, Venezuela, were determined by active and passive methods. In this region, water wells are contaminated by natural gas and gas leaks exist in the nearby river. Based on soil gas Radon data surface hydrocarbon seeps were identified. Radon and thoron concentration maps show anomalously high values near the river gas leaks decreasing in the direction of water wells where natural gas is also detected. The area where the highest concentrations of 222 Rn were detected seems to indicate the surface projection of the aquifer contaminated with natural gas. The Radon/Thoron ratio revealed a micro-localized anomaly, indicating the area where the gas comes from deep layers of the subsoil. The radon map determined by the passive method showed a marked positive anomaly around abandoned gas wells. The high anomalous Radon concentration localized near the trails of ascending gas bubbles at the river indicates the zone trough where natural gases are ascending with greater ease, associated with a deep geological fault, being this the main source of methane penetration into the aquifer. It is suggested that the source of the natural gas may be due to leaks at deep sites along the structure of some of the abandoned wells located at the North-East of the studied area. - Highlights: ► High Radon/Thoron ratios were localized near the natural-gas emanations in a river. ► Natural gases are ascending trough a deep geological fault. ► Apparently, the radon anomaly shows the site where natural gas enters the aquifer. ► Natural gas source may be related to leaks in the structure of abandoned gas wells

    Helsinki City Transport has decided to operate public transport in the center of the city with tramways and gas-fuelled busses. The decision is that there will be about 100 natural gas fueled busses in Helsinki by the year 2003. European exhaust gas emission (NO x and particulates) regulations have tightened strongly during the past few years. The regulations have forced to search for new fuels by the side of development of diesel engines. Alcohols, in spite of favourable fuel properties, are too expensive, so the use of them needs large subsidies for transportation sector. Gaseous fuels, both LPG and natural gas are suitable fuels for Otto cycle-cycle engines. After the previous oil crisis the interest in gas-fuelled engines has steadily decreased, but at present it is increasing again because of the objectives to decrease emissions of heavy vehicles at the level of gasoline-fuelled vehicles, equipped with three-way catalyst. From the point of view of emissions natural gas and LPG are seen as equivalent alternatives. The price of LPG varies on the basis of demand and on the basis of the prices of other oil products. Refuelling of a vehicle and storage of LPG in liquid form in the tank of the vehicle is easier than refuelling and fuel storage of natural gas. Investments to refuelling equipment of LPG are only 20% of those of the natural gas refuelling systems. The problem of natural gas is also the fact that is not easy to carry in the vehicle. Even if natural gas is compressed to pressure of 200 bars, it requires six times larger tanks if the refuelling intervals are the same. Liquefaction of natural gas reduces the volume significantly, but this is complicated and hence expensive. The tank of a vehicle should be vacuum insulated because the temperature of the LNG is about 160 deg C. Tank volume of LPG is only about twice that of diesel oil. Safety of natural gas is high, because it is lighter than the air, nearly a half of the density of the air. Octane ratings

  20. Price dynamics of natural gas and the regional methanol markets

    2010-01-01

    A 'methanol economy' based mainly on natural gas as a feedstock has a lot of potential to cope with the current and ongoing concerns for energy security along with the reduction of CO-2 emissions. It is, therefore, important to examine the price dynamics of methanol in order to ascertain whether the price of methanol is mainly natural-gas-cost driven or demand driven in the context of different regions. This paper is the first attempt to investigate the following: (1) is the natural gas price significantly related to the regional methanol prices in the Far East, United States and Europe? (2) who drives the regional methanol prices? The paper is motivated by the recent and growing debate on the lead-lag relationship between natural gas and methanol prices. Our findings, based on the most recently developed 'long-run structural modelling' and subject to the limitations of the study, tend to suggest: (1) natural gas price is cointegrated with the regional methanol prices, (2) our within-sample error-correction model results tend to indicate that natural gas was driving the methanol prices in Europe and the United States but not in the Far East. These results are consistent, during most of the period under review (1998.5-2007.3), with the surge in demand for methanol throughout the Far East, particularly in China, Taiwan and South Korea, which appears to have played a relatively more dominant role in the Far East compared to that in Europe and the United States within the framework of the dynamic interactions of input and product prices. However, during the post-sample forecast period as evidenced in our variance decompositions analysis, the emergence of natural gas as the main driver of methanol prices in all three continents is consistent with the recent surge in natural gas price fueled mainly, among others, by the strong hedging activities in the natural gas futures/options as well as refining tightness (similar to those that were happening in the crude oil markets
