Accounting for fuel price risk: Using forward natural gas prices instead of gas price forecasts to compare renewable to natural gas-fired generation  

Science Conference Proceedings (OSTI)

Against the backdrop of increasingly volatile natural gas prices, renewable energy resources, which by their nature are immune to natural gas fuel price risk, provide a real economic benefit. Unlike many contracts for natural gas-fired generation, renewable generation is typically sold under fixed-price contracts. Assuming that electricity consumers value long-term price stability, a utility or other retail electricity supplier that is looking to expand its resource portfolio (or a policymaker interested in evaluating different resource options) should therefore compare the cost of fixed-price renewable generation to the hedged or guaranteed cost of new natural gas-fired generation, rather than to projected costs based on uncertain gas price forecasts. To do otherwise would be to compare apples to oranges: by their nature, renewable resources carry no natural gas fuel price risk, and if the market values that attribute, then the most appropriate comparison is to the hedged cost of natural gas-fired generation. Nonetheless, utilities and others often compare the costs of renewable to gas-fired generation using as their fuel price input long-term gas price forecasts that are inherently uncertain, rather than long-term natural gas forward prices that can actually be locked in. This practice raises the critical question of how these two price streams compare. If they are similar, then one might conclude that forecast-based modeling and planning exercises are in fact approximating an apples-to-apples comparison, and no further consideration is necessary. If, however, natural gas forward prices systematically differ from price forecasts, then the use of such forecasts in planning and modeling exercises will yield results that are biased in favor of either renewable (if forwards forecasts). In this report we compare the cost of hedging natural gas price risk through traditional gas-based hedging instruments (e.g., futures, swaps, and fixed-price physical supply contracts) to contemporaneous forecasts of spot natural gas prices, with the purpose of identifying any systematic differences between the two. Although our data set is quite limited, we find that over the past three years, forward gas prices for durations of 2-10 years have been considerably higher than most natural gas spot price forecasts, including the reference case forecasts developed by the Energy Information Administration (EIA). This difference is striking, and implies that resource planning and modeling exercises based on these forecasts over the past three years have yielded results that are biased in favor of gas-fired generation (again, presuming that long-term stability is desirable). As discussed later, these findings have important ramifications for resource planners, energy modelers, and policy-makers.

An economic feasibility analysis of distributed electric power generation based upon the Natural Gas-Fired Fuel Cell: a model of the operations cost.  

DOE Green Energy (OSTI)

This model description establishes the revenues, expenses incentives and avoided costs of Operation of a Natural Gas-Fired Fuel Cell-Based. Fuel is the major element of the cost of operation of a natural gas-fired fuel cell. Forecasts of the change in the price of this commodity a re an important consideration in the ownership of an energy conversion system. Differences between forecasts, the interests of the forecaster or geographical areas can all have significant effects on imputed fuel costs. There is less effect on judgments made on the feasibility of an energy conversion system since changes in fuel price can affect the cost of operation of the alternatives to the fuel cell in a similar fashion. The forecasts used in this model are only intended to provide the potential owner or operator with the means to examine alternate future scenarios. The operations model computes operating costs of a system suitable for a large condominium complex or a residential institution such as a hotel, boarding school or prison. The user may also select large office buildings that are characterized by 12 to 16 hours per day of operation or industrial users with a steady demand for thermal and electrical energy around the clock.

This report is an account of the work performed from May 1, 1993 to July 30,1993 on the economic feasibility generating electrical power by natural gas-fired fuel cells. The study is comprised of a survey of energy users, the development of numeric models of an energy distribution system and a central plant utilities system that includes a fuel cell. A model of the capital cost of the hardware elements is combined with a series of ownership scenarios and an operations model that provide the necessary input for a model of the cost of ownership of a fuel cell-based power generation system. The primary model development tasks are complete. The remaining study emphasis is to perform an economic analysis of varied ownership scenarios using the model. This report outlines the progress to date.

Apples with apples: accounting for fuel price risk in comparisons of gas-fired and renewable generation  

DOE Green Energy (OSTI)

For better or worse, natural gas has become the fuel of choice for new power plants being built across the United States. According to the US Energy Information Administration (EIA), natural gas combined-cycle and combustion turbine power plants accounted for 96% of the total generating capacity added in the US between 1999 and 2002--138 GW out of a total of 144 GW. Looking ahead, the EIA expects that gas-fired technology will account for 61% of the 355 GW new generating capacity projected to come on-line in the US up to 2025, increasing the nationwide market share of gas-fired generation from 18% in 2002 to 22% in 2025. While the data are specific to the US, natural gas-fired generation is making similar advances in other countries as well. Regardless of the explanation for (or interpretation of) the empirical findings, however, the basic implications remain the same: one should not blindly rely on gas price forecasts when comparing fixed-price renewable with variable-price gas-fired generation contracts. If there is a cost to hedging, gas price forecasts do not capture and account for it. Alternatively, if the forecasts are at risk of being biased or out of tune with the market, then one certainly would not want to use them as the basis for resource comparisons or investment decisions if a more certain source of data (forwards) existed. Accordingly, assuming that long-term price stability is valued, the most appropriate way to compare the levelized cost of these resources in both cases would be to use forward natural gas price data--i.e. prices that can be locked in to create price certainty--as opposed to uncertain natural gas price forecasts. This article suggests that had utilities and analysts in the US done so over the sample period from November 2000 to November 2003, they would have found gas-fired generation to be at least 0.3-0.6 cents/kWh more expensive (on a levelized cost basis) than otherwise thought. With some renewable resources, in particular wind power, now largely competitive with gas-fired generation in the US (including the impact of the federal production tax credit and current high gas prices), a margin of 0.3-0.6 cents/kWh may in some cases be enough to sway resource decisions in favor of renewables.

Advanced natural gas-fired turbine system utilizing thermochemical recuperation and/or partial oxidation for electricity generation, greenfield and repowering applications  

SciTech Connect

The performance, economics and technical feasibility of heavy duty combustion turbine power systems incorporating two advanced power generation schemes have been estimated to assess the potential merits of these advanced technologies. The advanced technologies considered were: Thermochemical Recuperation (TCR), and Partial Oxidation (PO). The performance and economics of these advanced cycles are compared to conventional combustion turbine Simple-Cycles and Combined-Cycles. The objectives of the Westinghouse evaluation were to: (1) simulate TCR and PO power plant cycles, (2) evaluate TCR and PO cycle options and assess their performance potential and cost potential compared to conventional technologies, (3) identify the required modifications to the combustion turbine and the conventional power cycle components to utilize the TCR and PO technologies, (4) assess the technical feasibility of the TCR and PO cycles, (5) identify what development activities are required to bring the TCR and PO technologies to commercial readiness. Both advanced technologies involve the preprocessing of the turbine fuel to generate a low-thermal-value fuel gas, and neither technology requires advances in basic turbine technologies (e.g., combustion, airfoil materials, airfoil cooling). In TCR, the turbine fuel is reformed to a hydrogen-rich fuel gas by catalytic contact with steam, or with flue gas (steam and carbon dioxide), and the turbine exhaust gas provides the indirect energy required to conduct the endothermic reforming reactions. This reforming process improves the recuperative energy recovery of the cycle, and the delivery of the low-thermal-value fuel gas to the combustors potentially reduces the NO{sub x} emission and increases the combustor stability.

Science Conference Proceedings (OSTI)

This article describes the East Syracuse generating plant, one of first commercial stations to include LM6000 gas turbines, designed to solve noise and emissions problems. This natural-gas-fired, combined-cycle cogeneration facility provides 97 MW of power to Niagara Mohawk Power Corp and up to 80,000 lb/hr of process steam to a nearby Bristol-Myers Squibb Co plant. The plant's original design had contemplated a base-loaded facility. This stemmed from the original power sales agreement with Niagara Mohawk Power Corp. Flexibility of original design proved advantageous to the East Syracuse (NY) plant when, during the latter stages of construction, the original agreement was renegotiated into a schedulable'' contract. The new agreement now in force, providing for limited dispatch of one of the two gas turbines, is designed around other pre-existing project agreements. Design flexibility and the choice of two gas turbines made the plant capable of meeting dispatch requirements with only minor modifications of plant design and staffing.

Rise in gas-fired power generation tracks gains in turbine efficiency  

SciTech Connect

Natural gas-fueled gas turbines--in both simple and combined-cycle configurations--will account for most power generation capacity additions through 2000. It is widely agreed that gas turbines will remain the dominant form of technology for power generation for the next decade or two, making them the power generation technology of choice for today and the future. The pre-eminent stature of gas turbines can be attributed to their low capital costs, high efficiency, low emissions, short permitting and construction lead times, and proven reliability. The versatility of gas turbines also makes them unique among power generation technologies, as they can economically serve a wide spectrum of applications and sizes--from distributed generation to industrial cogeneration and central station generation. Three primary factors contribute to the growing interest in gas turbine-based power generation and the role gas turbines will play in the future power generation market: An optimistic outlook for the supply and price of natural gas; technology advances that have produced substantial improvements in efficiency and emissions; and emissions regulations that may favor the use of gas turbines over traditional fossil-fueled steam turbines. These three factors are discussed.

On use of CO{sub 2} chemiluminescence for combustion metrics in natural gas fired reciprocating engines.  

DOE Green Energy (OSTI)

Flame chemiluminescence is widely acknowledged to be an indicator of heat release rate in premixed turbulent flames that are representative of gas turbine combustion. Though heat release rate is an important metric for evaluating combustion strategies in reciprocating engine systems, its correlation with flame chemiluminescence is not well studied. To address this gap an experimental study was carried out in a single-cylinder natural gas fired reciprocating engine that could simulate turbocharged conditions with exhaust gas recirculation. Crank angle resolved spectra (266-795 nm) of flame luminosity were measured for various operational conditions by varying the ignition timing for MBT conditions and by holding the speed at 1800 rpm and Brake Mean effective Pressure (BMEP) at 12 bar. The effect of dilution on CO*{sub 2}chemiluminescence intensities was studied, by varying the global equivalence ratio (0.6-1.0) and by varying the exhaust gas recirculation rate. It was attempted to relate the measured chemiluminescence intensities to thermodynamic metrics of importance to engine research -- in-cylinder bulk gas temperature and heat release rate (HRR) calculated from measured cylinder pressure signals. The peak of the measured CO*{sub 2} chemiluminescence intensities coincided with peak pressures within {+-}2 CAD for all test conditions. For each combustion cycle, the peaks of heat release rate, spectral intensity and temperature occurred in that sequence, well separated temporally. The peak heat release rates preceded the peak chemiluminescent emissions by 3.8-9.5 CAD, whereas the peak temperatures trailed by 5.8-15.6 CAD. Such a temporal separation precludes correlations on a crank-angle resolved basis. However, the peak cycle heat release rates and to a lesser extent the peak cycle temperatures correlated well with the chemiluminescent emission from CO*{sub 2}. Such observations point towards the potential use of flame chemiluminescence to monitor peak bulk gas temperatures as well as peak heat release rates in natural gas fired reciprocating engines.

DOE Green Energy (OSTI)

This report presents results of Task 3 of the Westinghouse ATS Phase II program. Objective of Task 3 was to analyze and evaluate different cycles for the natural gas-fired Advanced Turbine Systems in order to select one that would achieve all ATS program goals. About 50 cycles (5 main types) were evaluated on basis of plant efficiency, emissions, cost of electricity, reliability-availability-maintainability (RAM), and program schedule requirements. The advanced combined cycle was selected for the ATS plant; it will incorporate an advanced gas turbine engine as well as improvements in the bottoming cycle and generator. Cost and RAM analyses were carried out on 6 selected cycle configurations and compared to the baseline plant. Issues critical to the Advanced Combined Cycle are discussed; achievement of plant efficiency and cost of electricity goals will require higher firing temperatures and minimized cooling of hot end components, necessitating new aloys/materials/coatings. Studies will be required in combustion, aerodynamic design, cooling design, leakage control, etc.

Capacity additions of gas-fired combined-cycle units reached a peak in 2003 and will drop sharply in 2004. While the extraordinary boom of merchant capacity is now largely over, it has resulted in overbuilding in many regions and will have impacts that are widespread. The overall efficiency of this new capacity has been strong, but trends toward greater capacity utilization have been arrested by the combination of overbuilding and high natural gas prices.

Development of an advanced gas-fired mineral wool melter. Final report, October 1987-December 1990  

SciTech Connect

A gas-fired mineral wool melter was successfully designed and tested. The test results clearly show that the gas-fired melter offers significant advantages over the current state-of-the-art system, the coke-fired cupola. The primary benefits offered are: lower energy costs, fewer airborne pollutant emissions, virtual elimination of solid waste generation and superior control and quality of the resultant melt stream. Specifically, the unit eliminates the emission of carbon monoxide, hydrogen sulfide and hydrocarbons. Emissions of SOx and particulate are substantially reduced as well. The generation of solid wastes is eliminated through the gas-fired melters ability to utilize untreated process wastes as a feedstock.

Accounting for fuel price risk when comparing renewable togas-fired generation: the role of forward natural gas prices  

SciTech Connect

Unlike natural gas-fired generation, renewable generation (e.g., from wind, solar, and geothermal power) is largely immune to fuel price risk. If ratepayers are rational and value long-term price stability, then--contrary to common practice--any comparison of the levelized cost of renewable to gas-fired generation should be based on a hedged gas price input, rather than an uncertain gas price forecast. This paper compares natural gas prices that can be locked in through futures, swaps, and physical supply contracts to contemporaneous long-term forecasts of spot gas prices. We find that from 2000-2003, forward gas prices for terms of 2-10 years have been considerably higher than most contemporaneous long-term gas price forecasts. This difference is striking, and implies that comparisons between renewable and gas-fired generation based on these forecasts over this period have arguably yielded results that are biased in favor of gas-fired generation.

Economic feasibility analysis of distributed electric power generation based upon the natural gas-fired fuel cell. Final report  

DOE Green Energy (OSTI)

The final report provides a summary of results of the Cost of Ownership Model and the circumstances under which a distributed fuel cell is economically viable. The analysis is based on a series of micro computer models estimate the capital and operations cost of a fuel cell central utility plant configuration. Using a survey of thermal and electrical demand profiles, the study defines a series of energy user classes. The energy user class demand requirements are entered into the central utility plant model to define the required size the fuel cell capacity and all supporting equipment. The central plant model includes provisions that enables the analyst to select optional plant features that are most appropriate to a fuel cell application, and that are cost effective. The model permits the choice of system features that would be suitable for a large condominium complex or a residential institution such as a hotel, boarding school or prison. Other applications are also practical; however, such applications have a higher relative demand for thermal energy, a characteristic that is well-suited to a fuel cell application with its free source of hot water or steam. The analysis combines the capital and operation from the preceding models into a Cost of Ownership Model to compute the plant capital and operating costs as a function of capacity and principal features and compares these estimates to the estimated operating cost of the same central plant configuration without a fuel cell.

Gas fired Advanced Turbine System  

SciTech Connect

The primary objective of the first phase of the Advanced Gas Turbine System (ATS) program was the concept definition of an advanced engine system that meets efficiency and emission goals far exceeding those that can be provided with today`s equipment. The thermal efficiency goal for such an advanced industrial engine was set at 50% some 15 percentage points higher than current equipment levels. Exhaust emissions goals for oxides of nitrogen (NO{sub x}), carbon monoxide (CO), and unburned hydrocarbons (UH) were fixed at 8 parts per million by volume (ppmv), 20 ppmv, and 20 ppmv respectively, corrected to 15% oxygen (O{sub 2}) levels. Other goals had to be addressed; these involved reducing the cost of power produced by 10 percent and improving or maintaining the reliability, availability, and maintainability (RAM) at current levels. This advanced gas turbine was to be fueled with natural gas, and it had to embody features that would allow it bum coal or coal derived fuels.

Interdependence of the Electricity Generation System and the Natural Gas System and Implications for Energy Security  

E-Print Network (OSTI)

Approved for public release; distribution is unlimited. Lexington Massachusetts This page intentionally left blank. EXECUTIVE SUMMARY Concern about energy security on domestic Department of Defense installations has led to the possibility of using natural gas-fired electricity generators to provide power in the event of electric grid failures. As natural gas is an increasingly base-load fuel for electricity generation in the United States, the electricity generation system has become increasingly dependent on the operation of the natural gas system. However, as the natural gas system is also partly dependent on electricity for its ability to deliver natural gas from the well-head to the consumer, the question arises of whether, in the event of an electric grid failure, the natural gas would continue to flow. As the natural gas transmission system largely uses natural gas from the pipelines as a source of power, once the gas has been extracted from the ground, the system is less dependent on the electric grid. However, some of the drilling rigs, processing units, and pipeline compressors do depend on electric power, making the vulnerability to the system to a disruption in the national electricity supply network vary depending on the cause, breadth, and geographic location of the disruption. This is due to the large numbers of players in the natural gas production and

An economic feasibility analysis of distributed electric power generation based upon the natural gas-fired fuel cell: a model of a central utility plant.  

DOE Green Energy (OSTI)

This central utilities plant model details the major elements of a central utilities plant for several classes of users. The model enables the analyst to select optional, cost effective, plant features that are appropriate to a fuel cell application. These features permit the future plant owner to exploit all of the energy produced by the fuel cell, thereby reducing the total cost of ownership. The model further affords the analyst an opportunity to identify avoided costs of the fuel cell-based power plant. This definition establishes the performance and capacity information, appropriate to the class of user, to support the capital cost model and the feasibility analysis. It is detailed only to the depth required to identify the major elements of a fuel cell-based system. The model permits the choice of system features that would be suitable for a large condominium complex or a residential institution such as a hotel, boarding school or prison. The user may also select large office buildings that are characterized by 12 to 16 hours per day of operation or industrial users with a steady demand for thermal and electrical energy around the clock.

Gas Fired Power Plants: Investment Timing, Operating Flexibility and Abandonment  

E-Print Network (OSTI)

Many firms are considering investment in gas fired power plants. We consider a firm holding a license, i.e. an option, to build a gas fired power plant. The operating cash flows from the plant depend on the spark spread, defined as the difference between the unit price of electricity and cost of gas. The plant produces electricity when the spark spread exceeds emission costs, otherwise the plant is ramped down and held idle. The owner has also an option to abandon the plant and realize the salvage value of the equipment. We compute optimal entry and exit threshold values for the spark spread. Also the effects of emission costs on the value of installing CO2 capture technology are analyzed.

Utilization of coal mine ventilation exhaust as combustion air in gas-fired turbines for electric and/or mechanical power generation. Semi-annual topical report, June 1995--August 1995  

SciTech Connect

Methane emitted during underground coal mining operations is a hazard that is dealt with by diluting the methane with fresh air and exhausting the contaminated air to the atmosphere. Unfortunately this waste stream may contain more than 60% of the methane resource from the coal, and in the atmosphere the methane acts as a greenhouse gas with an effect about 24.5 times greater than CO{sub 2}. Though the waste stream is too dilute for normal recovery processes, it can be used as combustion air for a turbine-generator, thereby reducing the turbine fuel requirements while reducing emissions. Preliminary analysis indicates that such a system, built using standard equipment, is economically and environmentally attractive, and has potential for worldwide application.

Gas-fired cooling status and trends  

SciTech Connect

The current US heating, ventilating, and air-conditioning (HVAC) market shows that the predictions of a health expansion in this market are attainable in this decade. The HVAC industry`s positive trade balance is widening; their successful hedge against various economic problems (the lack of financial and personnel resources) and their initiative to overcome the technical obstacles (caused by environmental issues) will have a positive, long-term impact. This along with energy availability and a favorable price structure has created a unique opportunity for the gas industry to regain and surpass previous respectable market shares attained with gas cooling technologies. New first generation gas cooling equipment is now entering the US marketplace with bold market predictions for commercial chillers and roof-top units, as well as for residential equipment. The marketing campaign covers a broad base of technical and supporting elements. It is the continued research, education, and training of engineers, architects, dealers, and utility sales personnel that can break the existing and serious barriers to the successful marketing of these cooling equipment products. Research in lowering equipment costs, personnel training, more units in the field, and more utility support in commercialization and deployment activities will guarantee an expansion of the market for the gas industry.

Active Humidity Control Through Gas-Fired Desiccant Humidity Pump  

E-Print Network (OSTI)

High equipment first cost and high operating costs, if electricity is used to drive such a system, have prohibited the application of active humidity control equipment in comfort conditioning in the past. Instead, passive techniques have been applied. A comparison of passive capacity control methods to control humidity shows that only the combined face and bypass and variable air volume system shows improved performance with respect to space humidity control, dew point depression, and response to perturbations. A gas-fired desiccant humidity pump will provide economical humidity control in existing and new construction using VAV or constant volume air distribution systems. The humidity pump is designed as a packaged make-up air module. It is coupled to new or existing conventional air-conditioning system via a duct. It consists of a triple integrated heat-exchanger combining (liquid) desiccant dehumidification with indirect evaporative cooling, a brine interchanger, and a gas-fired brine heater to regenerate the desiccant. Field experiments of two humidity pumps on existing commercial buildings have been initiated. Each system dehumidifies 5000 scfm of make-up air to meet all the latent loads, which is then fed to conventional, electric-driven HVAC equipment which meet all the sensible loads.

Modeling natural gas prices as a random walk: The advantages for generation planning  

SciTech Connect

Random walk modeling allows decision makers to evaluate risk mitigation strategies. Easily constructed, the random walk provides probability information that long-term fuel forecasts do not. This is vital to meeting the ratepayers` need for low-cost power, the shareholders` financial objectives, and the regulators` desire for straightforward information. Power generation planning depends heavily on long-term fuel price forecasts. This is particularly true for natural gas-fired plants, because fuel expenses are a significant portion of busbar costs and are subject to considerable uncertainty. Accurate forecasts, then, are critical - especially if electric utilities are to take advantage of the current low cost of natural gas technologies and their relatively clean burning characteristics, without becoming overdependent on a fuel that might significantly increase in price. Moreover, the transition to a more competitive generation market requires a more market-driven planning process. Current planning techniques use several long-term fuel forecasts - one serving as an expected case and others for sensitivity analysis - as inputs for modeling production costs. These forecasts are deterministic: For every time interval there is one, and only one projected fuel price - a serious limitation. Further, past natural gas price predictions have been erroneous and may be susceptible to bias. Today, deregulation of the natural gas production industry allows for a new approach in long-term fuel forecasting. Using NYMEX information, a random walk model of natural gas prices can be constructed. A random walk assumes that prices move randomly, and in modeling prices in this context one would be sure to include this all-important price volatility.

DEVELOPMENT OF FINE PARTICULATE EMISSION FACTORS AND SPECIATION PROFILES FOR OIL AND GAS FIRED COMBUSTION SYSTEMS  

SciTech Connect

This report provides results from the second year of this three-year project to develop dilution measurement technology for characterizing PM2.5 (particles with aerodynamic diameter smaller than 2.5 micrometers) and precursor emissions from stationary combustion sources used in oil, gas and power generation operation. Detailed emission rate and chemical speciation tests results for a gas turbine, a process heater, and a commercial oil/gas fired boiler are presented. Tests were performed using a research dilution sampling apparatus and traditional EPA methods. A series of pilot tests were conducted to identify the constraints to reduce the size of current research dilution sampler for future stack emission tests. Based on the test results, a bench prototype compact dilution sampler developed and characterized in GE EER in August 2002.

Dilution-based emissions sampling from stationary sources: part 2 - gas-fired combustors compared with other fuel-fired systems  

SciTech Connect

With the recent focus on fine particle matter (PM2.5), new, self- consistent data are needed to characterize emissions from combustion sources. Emissions data for gas-fired combustors are presented, using dilution sampling as the reference. The sampling and analysis of the collected particles in the presence of precursor gases, SO{sub 2}, nitrogen oxide, volatile organic compound, and NH{sub 3} is discussed; the results include data from eight gas fired units, including a dual- fuel institutional boiler and a diesel engine powered electricity generator. These data are compared with results in the literature for heavy-duty diesel vehicles and stationary sources using coal or wood as fuels. The results show that the gas-fired combustors have very low PM2.5 mass emission rates in the range of {approximately}10{sup -4} lb/million Btu (MMBTU) compared with the diesel backup generator with particle filter, with {approximately} 5 x 10{sup -3} lb/MMBTU. Even higher mass emission rates are found in coal-fired systems, with rates of {approximately} 0.07 lb/MMBTU for a bag-filter-controlled pilot unit burning eastern bituminous coal. The characterization of PM2.5 chemical composition from the gas-fired units indicates that much of the measured primary particle mass in PM2.5 samples is organic or elemental carbon and, to a much less extent, sulfate. Metal emissions are low compared with the diesel engines and the coal- or wood-fueled combustors. The metals found in the gas- fired combustor particles are low in concentration. The interpretation of the particulate carbon emissions is complicated by the fact that an approximately equal amount of particulate carbon is found on the particle collector and a backup filter. It is likely that measurement artifacts are positively biasing 'true' particulate carbon emissions results. 49 refs., 1 fig., 12 tabs.

A Gas-Fired Heat Pipe Zone Heater  

E-Print Network (OSTI)

A gas-fired vented zone heater has recently been developed by the Altar Corporation for Colorado State University (CSU) under a Gas Research Institute (GRI) contract. The unit war developed for auxiliary heating applications in passive solar buildings. An early prototype was tested at Altas and operated as expected. The final model was shipped to CSU in December 1983 for testing in the REPEAT Facility at CSU. A heat pipe extends through the wall to the outside of the building. It has a modest water charge which can freeze repeatedly with no damage, since the heat pips is only partially filled. Firing efficiency at 4,000 Btu/b (1.17 kW thermal) is approximately 80%. The unit features a 3 foot by 3 foot radiator mounted inside the room to be heated, and is thermostatically controlled. Ignition is accomplished with an electronic sparker (pilot). The radiator typically operates at 150-180°F (65-82°C), and has been operated at between 2,000 and 5,000 Btu/h (0.6-1.47 kW). Results of testing the vented heat pipe zone heater at CSU arm presented. Also, a method for determining the optimal combination of zone heater, passive solar heating and energy conservation measures has been developed. Nomographs have been developed that may be used by a building designer to determine the optimal combination of zone heater size, passive solar system size, and energy conservation measures for given types of passive solar heating systems in selected locations. A representative nomograph is presented along with a design example.

The combustion of natural gas in an atmospheric fluidized bed combined with heat transfer from the bed to the working fluid is shown to be an attractive means for supplying heat to closed cycle gas turbines. It is demonstrated how this concept can yield high thermal efficiencies without the use of high temperature resistant materials and yield low levels of pollutant emissions. The features of the combustor-heater are established for a 9000 kW closed cycle gas turbine generator and comparisons are made with a conventional open cycle machine.

A “natural” lexicalization model for language generation  

E-Print Network (OSTI)

We propose a general lexicalization model which accounts for how lexical units are selected and introduced in linguistic utterances during language generation. This model aims at “naturalness” by being based on actual lexical knowledge used in speech; consequently, it should be compatible with standard patterns of behavior shown by humans when they speak (flexibility in computing both content and form of linguistic utterances, prototypical types of mistakes and backtracking, etc.). The main advantage of our model, once implemented in automatic language generation, is that it takes into account fundamental differences that exist between lexical units, with regard to why and how they are used in texts. This is achieved by means of a stratificational approach to lexicalization, where each type of lexical unit is introduced at a proper level of representation, according to the role it plays in the enunciation. Section 1 offers a general characterization of the approach and makes explicit its main assumptions. Sections 2 to 4 successively examine the three levels of transition implied by the stratificational structuring of the model. Section 5 concludes with an examination of its relevance to the design of text generation systems. Keywords: language/text generation, lexicalization, lexical choice, Meaning-Text theory.

However, as a result, electricity prices have become highly volatile. Stochastic programming provides an appropriate method to characterise the uncertainty and to derive decisions while taking risk management into account.

Comparison of AEO 2009 Natural Gas Price Forecast to NYMEX Futures Prices  

SciTech Connect

On December 17, 2008, the reference-case projections from Annual Energy Outlook 2009 (AEO 2009) were posted on the Energy Information Administration's (EIA) web site. We at LBNL have, in the past, compared the EIA's reference-case long-term natural gas price forecasts from the AEO series to contemporaneous natural gas prices that can be locked in through the forward market, with the goal of better understanding fuel price risk and the role that renewables can play in mitigating such risk. As such, we were curious to see how the latest AEO reference-case gas price forecast compares to the NYMEX natural gas futures strip. This brief memo presents our findings. Note that this memo pertains only to natural gas fuel price risk (i.e., the risk that natural gas prices might differ over the life of a gas-fired generation asset from what was expected when the decision to build the gas-fired unit was made). We do not take into consideration any of the other distinct attributes of gas-fired and renewable generation, such as dispatchability (or lack thereof), differences in capital costs and O&M expenses, or environmental externalities. A comprehensive comparison of different resource types--which is well beyond the scope of this memo--would need to account for differences in all such attributes, including fuel price risk. Furthermore, our analysis focuses solely on natural-gas-fired generation (as opposed to coal-fired or nuclear generation, for example), for several reasons: (1) price volatility has been more of a concern for natural gas than for other fuels used to generate power; (2) for environmental and other reasons, natural gas has, in recent years, been the fuel of choice among power plant developers; and (3) natural gas-fired generators often set the market clearing price in competitive wholesale power markets throughout the United States. That said, a more-complete analysis of how renewables mitigate fuel price risk would also need to consider coal, uranium, and other fuel prices. Finally, we caution readers about drawing inferences or conclusions based solely on this memo in isolation: to place the information contained herein within its proper context, we strongly encourage readers interested in this issue to read through our previous, more-detailed studies, available at http://eetd.lbl.gov/ea/EMS/reports/53587.pdf or http://eetd.lbl.gov/ea/ems/reports/54751.pdf.

Efficiently generate steam from cogeneration plants  

SciTech Connect

As cogeneration gets more popular, some plants have two choices of equipment for generating steam. Plant engineers need to have a decision chart to split the duty efficiently between (oil-fired or gas-fired) steam generators (SGs) and heat recovery steam generators (HRSGs) using the exhaust from gas turbines. Underlying the dilemma is that the load-versus-efficiency characteristics of both types of equipment are different. When the limitations of each type of equipment and its capability are considered, analysis can come up with several selection possibilities. It is almost always more efficient to generate steam in an HRSG (designed for firing) as compared with conventional steam generators. However, other aspects, such as maintenance, availability of personnel, equipment limitations and operating costs, should also be considered before making a final decision. Loading each type of equipment differently also affects the overall efficiency or the fuel consumption. This article describes the performance aspects of representative steam generators and gas turbine HRSGs and suggests how plant engineers can generate steam efficiently. It also illustrates how to construct a decision chart for a typical installation. The equipment was picked arbitrarily to show the method. The natural gas fired steam generator has a maximum capacity of 100,000 lb/h, 400-psig saturated steam, and the gas-turbine-exhaust HRSG has the same capacity. It is designed for supplementary firing with natural gas.

Combustor design tool for a gas fired thermophotovoltaic energy converter  

DOE Green Energy (OSTI)

Recently, there has been a renewed interest in thermophotovoltaic (TPV) energy conversion. A TPV device converts radiant energy from a high temperature incandescent emitter directly into electricity by photovoltaic cells. The current Department of Energy sponsored research involves the design, construction and demonstration of a prototype TPV converter that uses a hydrocarbon fuel (such as natural gas) as the energy source. As the photovoltaic cells are designed to efficiently convert radiant energy at a prescribed wavelength, it is important that the temperature of the emitter be nearly constant over its entire surface. The US Naval Academy has been tasked with the development of a small emitter (with a high emissivity) that can be maintained at 1,756 K (2,700 F). This paper describes the computer spreadsheet model that was developed as a tool to be used for the design of the high temperature emitter.

Development and Validation of a Gas-Fired Residential Heat Pump Water Heater - Final Report  

SciTech Connect

For gas-fired residential water heating, the U.S. and Canada is predominantly supplied by minimum efficiency storage water heaters with Energy Factors (EF) in the range of 0.59 to 0.62. Higher efficiency and higher cost ($700 - $2,000) options serve about 15% of the market, but still have EFs below 1.0, ranging from 0.65 to 0.95. To develop a new class of water heating products that exceeds the traditional limit of thermal efficiency, the project team designed and demonstrated a packaged water heater driven by a gas-fired ammonia-water absorption heat pump. This gas-fired heat pump water heater can achieve EFs of 1.3 or higher, at a consumer cost of $2,000 or less. Led by Stone Mountain Technologies Inc. (SMTI), with support from A.O. Smith, the Gas Technology Institute (GTI), and Georgia Tech, the cross-functional team completed research and development tasks including cycle modeling, breadboard evaluation of two cycles and two heat exchanger classes, heat pump/storage tank integration, compact solution pump development, combustion system specification, and evaluation of packaged prototype GHPWHs. The heat pump system extracts low grade heat from the ambient air and produces high grade heat suitable for heating water in a storage tank for domestic use. Product features that include conventional installation practices, standard footprint and reasonable economic payback, position the technology to gain significant market penetration, resulting in a large reduction of energy use and greenhouse gas emissions from domestic hot water production.

According to the Energy Information Administration's (EIA) recently released Electric Power Monthly, natural gas net generation rose by 21 percent from 2011 to 2012 (the biggest increase since an 11 percent rise in 1994) as low natural gas prices encouraged more natural gas consumption in the electric power sector. Natural gas generation displaced some coal generation, which fell about 12 percent from 2011 to 2012. During 2012, an extremely hot summer combined with low natural gas prices relative to coal led to record high gas-fired power generation. BENTEK

Development of an advanced gas-fired mineral-wool melter. Annual report, January-December 1988  

SciTech Connect

A gas-fired mineral-wool melter was designed to provide a melting technology option to the existing coke-fired cupola melters used by the mineral wool industry. Over the past few years, mineral-wool producers have been increasingly pressured to reduce their level of pollutant gaseous emissions. Including the fuel consumption for an afterburner required with a cupola melter, the direct production costs for fuel currently range from $32 to $44 per ton of melted product; dependent on the effectiveness of a heat-recovery system. The estimated direct fuel cost for a gas-fired mineral-wool melter could be as low as $16 per ton. The configuration of the prototype melter contributes to the energy savings because waste heat is reclaimed by preheating the feedstock in a counterflow shaft. Besides the beneficial decrease in energy costs, the proposed gas-fired melter will virtually eliminate carbon monoxide and unburned hydrocarbon emissions as well as substantially reduce emissions of hydrogen sulfide. Finally, with an improved capability to process the melted product at a controlled temperature and flow rate, the gas-fired melter should improve the overall quality of the mineral fiber product compared to the state-of-the-art coke-fired cupola melter.

Method for providing variable output gas-fired furnace with a constant temperature rise and efficiency  

Science Conference Proceedings (OSTI)

A method is described for providing a variable output gas-fired furnace means with a constant temperature rise and efficiency where the furnace means includes burners, a blower, a thermostat and a delay timer, the method comprising the steps of: sensing the temperature in an area to be conditioned; comparing the sensed temperature to a predetermined set point; if the sensed temperature deviates from the predetermined set point by more than a predetermined amount, gas is supplied to the burners and the blower is started; determining the reference revolution per minute of the blower; determining the reference cubic feet per minute delivered by the blower; determining the manifold pressure; determining whether the furnace is in a high heat or a low heat mode of operation; determining the desired cubic feet per minute delivered by the blower for the current mode of operation; reading the actual revolution per minute of the blower; adjusting the speed of the blower motor if the actual and desired revolution per minute of the blower are not the same; determining whether the thermostat is satisfied; if the thermostat is not satisfied, returning to the step of determining the manifold pressure; and if the thermostat is satisfied, shutting off the gas and starting the delay timer.

Gas fired advanced turbine system. Phase 1, System scoping and feasibility studies  

DOE Green Energy (OSTI)

The basic concept thus derived from the Ericsson cycle is an intercooled, recuperated, and reheated gas turbine. Theoretical performance analyses, however, showed that reheat at high turbine rotor inlet temperatures (TRIT) did not provide significant efficiency gains and that the 50 percent efficiency goal could be met without reheat. Based upon these findings, the engine concept adopted as a starting point for the gas-fired advanced turbine system is an intercooled, recuperated (ICR) gas turbine. It was found that, at inlet temperatures greater than 2450{degrees}F, the thermal efficiency could be maintained above 50%, provided that the turbine cooling flows could be reduced to 7% of the main air flow or lower. This dual and conflicting requirement of increased temperatures and reduced cooling will probably force the abandonment of traditional air cooled turbine parts. Thus, the use of either ceramic materials or non-air cooling fluids has to be considered for the turbine nozzle guide vanes and turbine blades. The use of ceramic components for the proposed engine system is generally preferred because of the potential growth to higher temperatures that is available with such materials.

Thermal energy storage for power generation  

SciTech Connect

Studies strongly indicate that the United States will face widespread electrical power constraints in the 1990s, with most regions of the country experiencing capacity shortages by the year 2000. In many cases, the demand for increased power will occur during intermediate and peak demand periods. Much of this demand is expected to be met by oil- and natural gas-fired Brayton cycle turbines and combined-cycle plants. While natural gas is currently plentiful and reasonably priced, the availability of an economical long-term coal-fired option for peak and intermediate load power generation will give electric power utilities an option in case either the availability or cost of natural gas should deteriorate. 54 refs., 5 figs., 17 tabs.

The development of solar-assisted gas-fired appliances: phase ii. Final report dec 80-nov 81  

SciTech Connect

An evaluation of applying solar assistance to commercial laundry drying and supermarket dehumidification was accomplished. The laundry drying project included experimental evaluation of the transient and steady-state characteristics of the hot air produced by an air-heating solar collector; experimental evaluation of the performance characteristics of a gas-fired laundry dryer as affected by varying the inlet air temperature and humidity; and an assessment of the characteristics of commercial laundries in relation to the potential commercialization of the solar-assisted dryer concept. The supermarket dehumidification project included an assessment of the relative latent and sensible cooling requirements as a function of geographic location; typical design studies of the performance and cost effectiveness of desiccant dehumidification systems in this application; and the incremental effectiveness of solar assistance to desiccant regeneration. In both projects, the solar-assist feature is, at best, marginally cost effective, including incentives, in the near term; however, the gas-fired only desiccant dehumidification concept is shown to be a potentially attractive alternative to vapor compression dehumidification with a potential for widespread application.

Advanced natural gas fuel technologies for military installations. Final report  

SciTech Connect

Energy conservation efforts reduced Department of Defense (DoD) fossil fuel consumption considerably between FYX5 and FY9 I, yet electricity consumption increased. Electricity consumption accounts for only one-third of DoD energy use, but over half of DoD energy costs. In addition, the production of electricity at coal or nuclear plants often creates environmental concerns, while the use of clean-burning natural gas does not; its use can help DoD bases comply with increasingly stringent environmental regulations. Recent developments in natural gas-fired technologies also demonstrate improved efficiency and productivity at lower costs. This report identifies state-of-the-art and emerging natural gas utilization technologies with potential application on DoD installations. This report describes various technologies that have potential residential, commercial, or industrial applications on DoD installations. Applications include heating, cooling, power generation, food preparation, and several industrial processes.

Variability in natural gas fuel composition and its effects on the performance of catalytic combustion systems. Final report for period September 18, 1998 - September 17, 2000  

SciTech Connect

Natural gas is composed primarily of methane with small amounts of higher hydrocarbons and diluents, which vary by region and over time. Compositions of natural gas from domestic and worldwide sources were surveyed with respect to content of higher hydrocarbons and diluents. The survey showed slight compositional variability between most of the gases, with a small fraction of them containing significantly larger contents of higher hydrocarbons than the mean. As gas-fired turbines will be used for power generation all over the world, they will need to tolerate operation with fuels with a wide variety of compositions, particularly with respect to the concentration of higher hydrocarbons and diluents. Subscale catalytic combustion modules typical of those used in gas turbine power generation with ultra low emissions of pollutants were tested in a subscale test system with natural gas alone and with added known levels of hydrocarbon compounds and diluents. The range of compositions tested contained the range observed in the survey. Test results were used to calculate the effect of composition on catalyst performance. The compositional variability is of little consequence to the catalyst for most of the gases in the survey, including nearly all of the gases delivered in the U.S. To accommodate the remaining gases, the catalyst inlet temperature must be lowered to maintain combustor durability. These results support commercial acceptance of catalytic combustion systems for use in natural gas fired turbines in distributed power generation with ultra low NO{sub x} emissions.

Gas-fired desiccant dehumidification system field evaluation in a quick-service restaurant. Final report, October 1989  

Science Conference Proceedings (OSTI)

This report describes the results of a field evaluation of state-of-art desiccant dehumidification equipment in Houston, TX. The evaluation demonstrated that comfort control in a quick-service restaurant could be improved dramatically. However, available gas-fired desiccant dehumidification equipment is too expensive, inefficient, and unreliable to be considered for wide application in the restaurant industry. Results of a technical and economic analysis of four HVAC options in four U.S. cities indicated that improved comfort control could be achieved with only a modest increase in operating costs with an advanced system. This, coupled with the economic benefits achieved through lower indoor humidity such as improved crew performance and reduced maintenance costs, could justify the introduction of an advanced, integrated, HVAC system using desiccant technology which has an installed cost similar to current equipment.

Operation Synopsis of Gas-Fired Double-Effect Absorption Chillers  

E-Print Network (OSTI)

Absorption refrigeration systems are one of the oldest systems available. The fundamentals of absorption refrigeration were formulated about 1777, and the first successful absorption machine was developed in 1850. The first U.S. patent for an absorption refrigeration system was issued in 1860. Absorption systems can use many different heat sources to produce the refrigeration effect: natural gas, steam, solar, and oil. While absorption systems were popular in the U.S. in the early part of the 20th century, their use declined in the mid twentieth century for several reasons: (1) increased reliability of vapor compression systems, (2) dropping electric prices (in real dollars), and (3) rapidly increasing gas prices. In recent years, there has been a resurgence of interest in absorption refrigeration and cooling. Natural gas prices have moderated while electric prices continue to rise. The reliability and performance of absorption systems have been substantially improved with new technology from Japan. This paper summarizes the results of the operation of three absorption systems located in the greater Dallas/Ft. Worth area.

Natural Gas Weekly Update  

Gasoline and Diesel Fuel Update (EIA)

8, 2001 8, 2001 Prices ended the week up slightly from where they started as a brief heat wave in the eastern half of the country caused a rise in prices (See Temperature Map) (See Deviation from Normal Temperatures Map) that was somewhat undone by the return of moderate temperatures and the report of another hefty stock build. On a Friday-to-Friday basis, the spot price at the Henry Hub increased by $0.25 to $3.88 per MMBtu compared with an increase of $0.23 to $0.33 at other major supply points in the eastern half of the country. In the same time period, the near-month (July delivery) futures contract was up less than 6 cents to $3.979 per MMBtu as of Friday, June 15, 2001. Prices in California rose substantially last Monday after coming off high inventory flow orders (OFOs) but ended the week close to or lower than the previous week due to another round of OFOs. For the past 7 weeks, weekly storage injections neared or exceeded 100 Bcf, bringing stocks to within less than a 1 percent difference from average levels. The string of record-breaking stock builds appears attributable to moderate spring temperatures and reduced cooling demand by natural-gas-fired electricity generation.

Gas-fired chiller-heaters as a central plant alternative for small office buildings  

SciTech Connect

Gas absorption chillers-heaters have been applied successfully in large projects where use of multiple chillers is feasible. Large facilities typically have a substantial base cooling load. If the base load is greater than 30% of the minimum capacity of the smallest chiller, chiller-heaters alone can be used as the building central plant. However, this study shows that a small office building presents part-load design difficulties that tend to favor the use of other technologies. The engineer can overcome these application problems by a variety of means, as has been illustrated. Manufacturers, too, are addressing the problems associated with low-load operation of direct-fired chiller heaters. A new generation of chiller-heaters that can unload down to 10% of design load will soon be available. If these new machines are capital-cost-competitive and perform up to expectations, the routine application of chiller-heaters in small commercial buildings may be just around the corner.

Magnetic Field Generation in Planets and Satellites by Natural Nuclear Fission Reactors  

E-Print Network (OSTI)

One of the most fundamental problems in physics has been to understand the nature of the mechanism that generates the geomagnetic field and the magnetic fields of other planets and satellites. For decades, the dynamo mechanism, thought to be responsible for generating the geomagnetic field and other planetary magnetic fields, has been ascribed to convection in each planet's iron-alloy core. Recently, I described the problems inherent in Earth-core convection and proposed instead that the geomagnetic field is produced by a dynamo mechanism involving convection, not in the fluid core, but in the electrically conductive, fluid, fission-product sub-shell of a natural nuclear fission reactor at the center of the Earth, called the georeactor. Here I set forth in detail the commonality in the Solar System of the matter like that of the inside of the Earth, which is my basis for generalizing the concept of planetary magnetic field generation by natural planetocentric nuclear fission reactors.

Life Cycle GHG Emissions from Conventional Natural Gas Power Generation: Systematic Review and Harmonization (Presentation)  

SciTech Connect

This research provides a systematic review and harmonization of the life cycle assessment (LCA) literature of electricity generated from conventionally produced natural gas. We focus on estimates of greenhouse gases (GHGs) emitted in the life cycle of electricity generation from conventionally produced natural gas in combustion turbines (NGCT) and combined-cycle (NGCC) systems. A process we term "harmonization" was employed to align several common system performance parameters and assumptions to better allow for cross-study comparisons, with the goal of clarifying central tendency and reducing variability in estimates of life cycle GHG emissions. This presentation summarizes preliminary results.

SULFUR REMOVAL FROM PIPE LINE NATURAL GAS FUEL: APPLICATION TO FUEL CELL POWER GENERATION SYSTEMS  

DOE Green Energy (OSTI)

Pipeline natural gas is being considered as the fuel of choice for utilization in fuel cell-based distributed generation systems because of its abundant supply and the existing supply infrastructure (1). For effective utilization in fuel cells, pipeline gas requires efficient removal of sulfur impurities (naturally occurring sulfur compounds or sulfur bearing odorants) to prevent the electrical performance degradation of the fuel cell system. Sulfur odorants such as thiols and sulfides are added to pipeline natural gas and to LPG to ensure safe handling during transportation and utilization. The odorants allow the detection of minute gas line leaks, thereby minimizing the potential for explosions or fires.

Transition metal catalysis in the generation of petroleum and natural gas. Progress report, [1992--1993  

DOE Green Energy (OSTI)

A new hypothesis is introduced for the generation of petroleum and natural gas. The transition metals, activated under the reducing conditions of diagenesis, are proposed as catalysts in the generation of light hydrocarbons. The objective of this proposal is to test that hypothesis. Transition metals (Ni, V, Ti, Co, Fe), in kerogen, porphyrins, and as pure compounds, will be tested under catagenic conditions for catalytic activity in the conversion of normal paraffins and hydrogen into light hydrocarbons. If the hypothesis is correct, kerogenous transition metals should become catalytically active under the reducing conditions of diagenesis and catalyze the conversion of paraffins into the light hydrocarbons seen in petroleum. Moreover, the C{sub 1}-C{sub 4} hydrocarbons generated catalytically should be similar in molecular and isotopic compositions to natural gas.

Variance Analysis of Wind and Natural Gas Generation under Different Market Structures: Some Observations  

DOE Green Energy (OSTI)

Does large scale penetration of renewable generation such as wind and solar power pose economic and operational burdens on the electricity system? A number of studies have pointed to the potential benefits of renewable generation as a hedge against the volatility and potential escalation of fossil fuel prices. Research also suggests that the lack of correlation of renewable energy costs with fossil fuel prices means that adding large amounts of wind or solar generation may also reduce the volatility of system-wide electricity costs. Such variance reduction of system costs may be of significant value to consumers due to risk aversion. The analysis in this report recognizes that the potential value of risk mitigation associated with wind generation and natural gas generation may depend on whether one considers the consumer's perspective or the investor's perspective and whether the market is regulated or deregulated. We analyze the risk and return trade-offs for wind and natural gas generation for deregulated markets based on hourly prices and load over a 10-year period using historical data in the PJM Interconnection (PJM) from 1999 to 2008. Similar analysis is then simulated and evaluated for regulated markets under certain assumptions.

Emissions Benefits of Distributed Generation in the Texas Market  

Science Conference Proceedings (OSTI)

One potential benefit of distributed generation (DG) is a net reduction in air emissions. While DG will produce emissions, most notably carbon dioxide and nitrogen oxides, the power it displaces might have produced more. This study used a system dispatch model developed at Oak Ridge National Laboratory to simulate the 2012 Texas power market with and without DG. This study compares the reduction in system emissions to the emissions from the DG to determine the net savings. Some of the major findings are that 85% of the electricity displaced by DG during peak hours will be simple cycle natural gas, either steam or combustion turbine. Even with DG running as baseload, 57% of electricity displaced will be simple cycle natural gas. Despite the retirement of some gas-fired steam units and the construction of many new gas turbine and combined cycle units, the marginal emissions from the system remain quite high (1.4 lb NO{sub x}/MWh on peak and 1.1 lb NO{sub x}/MWh baseload) compared to projected DG emissions. Consequently, additions of DG capacity will reduce emissions in Texas from power generation in 2012. Using the DG exhaust heat for combined heat and power provides an even greater benefit, since it eliminates further boiler emissions while adding none over what would be produced while generating electricity. Further studies are warranted concerning the robustness of the result with changes in fuel prices, demands, and mixes of power generating technology.

The DOE/NREL Next Generation Natural Gas Vehicle Program - An Overview  

DOE Green Energy (OSTI)

This paper summarizes the Next Generation Natural Gas Vehicle (NG-NGV) Program that is led by the U.S. Department Of Energy's (DOE's) Office of Heavy Vehicle Technologies (OHVT) through the National Renewable Energy Laboratory (NREL). The goal of this program is to develop and implement one Class 3-6 compressed natural gas (CNG) prototype vehicle and one Class 7-8 liquefied natural gas (LNG) prototype vehicle in the 2004 to 2007 timeframe. OHVT intends for these vehicles to have 0.5 g/bhp-hr or lower emissions of oxides of nitrogen (NOx) by 2004 and 0.2 g/bhp-hr or lower NOx by 2007. These vehicles will also have particulate matter (PM) emissions of 0.01 g/bhp-hr or lower by 2004. In addition to ambitious emissions goals, these vehicles will target life-cycle economics that are compatible with their conventionally fueled counterparts.

Investment and Upgrade in Distributed Generation under Uncertainty  

Science Conference Proceedings (OSTI)

The ongoing deregulation of electricity industries worldwide is providing incentives for microgrids to use small-scale distributed generation (DG) and combined heat and power (CHP) applications via heat exchangers (HXs) to meet local energy loads. Although the electric-only efficiency of DG is lower than that of central-station production, relatively high tariff rates and the potential for CHP applications increase the attraction of on-site generation. Nevertheless, a microgrid contemplatingthe installation of gas-fired DG has to be aware of the uncertainty in the natural gas price. Treatment of uncertainty via real options increases the value of the investment opportunity, which then delays the adoption decision as the opportunity cost of exercising the investment option increases as well. In this paper, we take the perspective of a microgrid that can proceed in a sequential manner with DG capacity and HX investment in order to reduce its exposure to risk from natural gas price volatility. In particular, with the availability of the HX, the microgrid faces a tradeoff between reducing its exposure to the natural gas price and maximising its cost savings. By varying the volatility parameter, we find that the microgrid prefers a direct investment strategy for low levels of volatility and a sequential one for higher levels of volatility.

Decoding the `Nature Encoded' Messages for Distributed Energy Generation Control in Microgrid  

E-Print Network (OSTI)

The communication for the control of distributed energy generation (DEG) in microgrid is discussed. Due to the requirement of realtime transmission, weak or no explicit channel coding is used for the message of system state. To protect the reliability of the uncoded or weakly encoded messages, the system dynamics are considered as a `nature encoding' similar to convolution code, due to its redundancy in time. For systems with or without explicit channel coding, two decoding procedures based on Kalman filtering and Pearl's Belief Propagation, in a similar manner to Turbo processing in traditional data communication systems, are proposed. Numerical simulations have demonstrated the validity of the schemes, using a linear model of electric generator dynamic system.

Restoring Equilibrium to Natural Gas Markets: Can Renewable Energy Help?  

Science Conference Proceedings (OSTI)

Heightened natural gas prices have emerged as a key energy-policy challenge for at least the early part of the 21st century. With the recent run-up in gas prices and the expected continuation of volatile and high prices in the near future, a growing number of voices are calling for increased diversification of energy supplies. Proponents of renewable energy technologies identify these clean energy sources as an important part of the solution. Increased deployment of renewable energy (RE) can hedge natural gas price risk in more than one way, but a recent report by Berkeley Lab evaluates one such benefit in detail: by displacing gas-fired electricity generation, RE reduces natural gas demand and thus puts downward pressure on gas prices. Many recent modeling studies of increased RE deployment have demonstrated that this ''secondary'' effect of lowering natural gas prices could be significant; as a result, this effect is increasingly cited as justification for policies promoting RE. The Berkeley Lab report summarizes recent modeling studies that have evaluated the impact of RE deployment on gas prices, reviews the reasonableness of the results of these studies in light of economic theory and other research, and develops a simple tool that can be used to evaluate the impact of RE on gas prices without relying on a complex national energy model.

The Future of Combustion Turbine Technology for Industrial and Utility Power Generation  

E-Print Network (OSTI)

Low capital cost and ample low-cost natural gas supplies will make natural gas-fired combustion turbine systems the power generation technology of choice over the next decade. Against the background of earlier use by electric utilities, this paper examines the status, economic outlook, and future directions of combustion turbine technology for industrial and utility power generation. The discussion takes into account the ongoing deregulation and increasing competition that are shaping the electric power generation business. Included is a comparison between heavy-duty industrial combustion turbines and their rapidly evolving competition, aeroderivative machines, with emphasis on the appropriate application of each. The prospects for future improvements in the cost and performance of combustion turbines are reviewed, and the likely impact of advanced combustion turbine power generation concepts is considered. Also summarized is the outlook for power generation fuels, including the longer term reemergence of coal and the potential for widespread use of coal gasification-based combustion turbine systems. The paper draws heavily from a technical, economic, and business analysis, Combustion Turbine Power Systems, recently completed by SFA Pacific. The analysis was sponsored by an international group of energy companies that includes utilities, independent power producers (IPPs), and power industry equipment vendors.

Comparing the risk profiles of renewable and natural gas electricity contracts: A summary of the California Department of Water Resources contracts  

SciTech Connect

Electricity markets in the United States have witnessed unprecedented instability over the last few years, with substantial volatility in wholesale market prices, significant financial distress among major industry organizations, and unprecedented legal, regulatory and legislative activity. These events demonstrate the considerable risks that exist in the electricity industry. Recent industry instability also illustrates the need for thoughtful resource planning to balance the cost, reliability, and risk of the electricity supplied to end-use customers. In balancing different supply options, utilities, regulators, and other resource planners must consider the unique risk profiles of each generating source. This paper evaluates the relative risk profiles of renewable and natural gas generating plants. The risks that exist in the electricity industry depend in part on the technologies that are used to generate electricity. Natural gas has become the fuel of choice for new power plant additions in the United States. To some, this emphasis on a single fuel source signals the potential for increased risk. Renewable generation sources, on the other hand, are frequently cited as a potent source of socially beneficial risk reduction relative to natural gas-fired generation. Renewable generation is not risk free, however, and also imposes certain costs on the electricity sector. This paper specifically compares the allocation and mitigation of risks in long-term natural gas-fired electricity contracts with the allocation and mitigation of these same risks in long-term renewable energy contracts. This comparison highlights some of the key differences between renewable and natural gas generation that decision makers should consider when making electricity investment and contracting decisions. Our assessment is relevant in both regulated and restructured markets. In still-regulated markets, the audience for this report clearly includes regulators and the utilities they regulate. In restructured markets, the role of regulatory oversight of resource planning is more limited. Nonetheless, even in restructured markets, it is increasingly recognized that regulators have a critical role to play in directing the resource planning of providers of last resort--electric suppliers that provide service to those customers who choose not to switch to a competitive supplier. Our review of electricity contracts may also have educational value for those unfamiliar with the typical contents of these agreements. Details of our findings are provided in the body of the paper, but this summary is written to provide a concise alternative to reading the full report.

Techno-economic analysis of using corn stover to supply heat and power to a corn ethanol plant - Part 2: Cost of heat and power generation systems  

Science Conference Proceedings (OSTI)

This paper presents a techno-economic analysis of corn stover fired process heating (PH) and the combined heat and power (CHP) generation systems for a typical corn ethanol plant (ethanol production capacity of 170 dam3). Discounted cash flow method was used to estimate both the capital and operating costs of each system and compared with the existing natural gas fired heating system. Environmental impact assessment of using corn stover, coal and natural gas in the heat and/or power generation systems was also evaluated. Coal fired process heating (PH) system had the lowest annual operating cost due to the low fuel cost, but had the highest environmental and human toxicity impacts. The proposed combined heat and power (CHP) generation system required about 137 Gg of corn stover to generate 9.5 MW of electricity and 52.3 MW of process heat with an overall CHP efficiency of 83.3%. Stover fired CHP system would generate an annual savings of 3.6 M$ with an payback period of 6 y. Economics of the coal fired CHP system was very attractive compared to the stover fired CHP system due to lower fuel cost. But the greenhouse gas emissions per Mg of fuel for the coal fired CHP system was 32 times higher than that of stover fired CHP system. Corn stover fired heat and power generation system for a corn ethanol plant can improve the net energy balance and add environmental benefits to the corn to ethanol biorefinery.

Natural Gas Weekly Update  

Gasoline and Diesel Fuel Update (EIA)

9, 2001 9, 2001 Prices headed up the middle of last week despite seasonal or cooler temperatures everywhere but California (See Temperature Map) (See Deviation from Normal Temperatures Map) and the July 4th holiday, regarded as one of the lowest natural gas consumption days. As expected, the resulting 10-cent-per-MMBtu gain at the Henry Hub on Thursday compared with the previous Friday was undone the following day. The futures price for August delivery was able to stay ahead of the previous week by 12.2 cents to settle at $3.218 on Friday. Spot natural gas prices for large packages in southern California increased as much as $2.71 per MMBtu as temperatures soared and gas-fired power plants endeavored to meet air conditioning demand. Prices started to recede as temperatures abated by the end of the week. Strong gas supplies across the country supported another hefty net addition to storage of 105 Bcf.

DEVELOPMENT OF FINE PARTICULATE EMISSION FACTORS AND SPECIATION PROFILES FOR OIL AND GAS-FIRED COMBUSTION SYSTEMS  

SciTech Connect

In 1997, the United States Environmental Protection Agency (EPA) promulgated new National Ambient Air Quality Standards (NAAQS) for particulate matter, including for the first time particles with aerodynamic diameter smaller than 2.5 micrometers ({micro}m) referred to as PM2.5. PM2.5 in the atmosphere also contributes to reduced atmospheric visibility, which is the subject of existing rules for siting emission sources near Class 1 areas and new Regional Haze rules. There are few existing data regarding emissions and characteristics of fine aerosols from oil, gas and power generation industry combustion sources, and the information that is available is generally outdated and incomplete. Traditional stationary source air emission sampling methods tend to underestimate or overestimate the contribution of the source to ambient aerosols because they do not properly account for primary aerosol formation, which occurs after the gases leave the stack. Primary aerosol includes both filterable particles that are solid or liquid aerosols at stack temperature plus those that form as the stack gases cool through mixing and dilution processes in the plume downwind of the source. These deficiencies in the current methods can have significant impacts on regulatory decision-making. PM2.5 measurement issues were extensively reviewed by the American Petroleum Institute (API) (England et al., 1998), and it was concluded that dilution sampling techniques are more appropriate for obtaining a representative particulate matter sample from combustion systems for determining PM2.5 emission rate and chemical speciation. Dilution sampling is intended to collect aerosols including those that condense and/or react to form solid or liquid aerosols as the exhaust plume mixes and cools to near-ambient temperature immediately after the stack discharge. These techniques have been widely used in recent research studies. For example, Hildemann et al. (1994) and McDonald et al. (1998) used filtered ambient air to dilute the stack gas sample followed by 80-90 seconds residence time to allow aerosol formation and growth to stabilize prior to sample collection and analysis. More accurate and complete emissions data generated using the methods developed in this program will enable more accurate source-receptor and source apportionment analysis for PM2.5 National Ambient Air Quality Standards (NAAQS) implementation and streamline the environmental assessment of oil, gas and power production facilities. The overall goals of this program were to: (1) Develop improved dilution sampling technology and test methods for PM2.5 mass emissions and speciation measurements, and compare results obtained with dilution and traditional stationary source sampling methods. (2) Develop emission factors and speciation profiles for emissions of fine particulate matter, especially organic aerosols, for use in source-receptor and source apportionment analyses. (3) Identify and characterize PM2.5 precursor compound emissions that can be used in source-receptor and source apportionment analyses.

Tax barriers to solar central receiver generation technology  

DOE Green Energy (OSTI)

Tax loads and required revenues are estimated for current and future solar central receiver and gas-fired plants competing in the same market. An economic measure of tax equity is used to evaluate the equity of the tax loads under past and present tax codes. The same measure is used to devise a tax strategy which produces the following two types of equitable taxation: (1) the two plants carry nearly equal tax loads, and (2) local, state and federal governments receive the same distribution of revenues from the solar plant as from the gas-fired plant `Me results show that central receivers (and likely other capital-intensive technologies) carry higher tax loads compared to competing gasfired generation, that tax loads are highly correlated with competitiveness, and that equitable taxation is feasible within the boundaries of the study.

Imported LNG (liquid natural gas) as an alternative fuel  

SciTech Connect

Imports of liquefied natural gas (LNG) first arrived in the United States in 1972 at the rate of one billion cubic feet (Bcf) per year. By 1979, they had reached 252 Bcf/year. However, as US as demand declined and domestic deliverability grew, inflexible LNG prices led to the complete collapse of trade during the 1980s. In 1987, all four US import terminals were idle and no LNG was imported. The situation bean to change with renegotiation of Distrigas' contract to import LNG from Algeria's Sonatrach. In 1988, the company imported 19 Bcf of gas to its Everett, Massachusetts terminal, with greater volumes in 1989. Panhandle Eastern has also renegotiated its Algerian supply contract and reactivated the company's Trunkline LNG terminal at Lake Charles, Louisiana. It received its first cargo in December 1989. Moves are also being made to bring the other two US import terminals, at Cove Point, Maryland and Elba Island, Georgia, back into service. On the supply side too, there are major new developments. Not only is Algeria seeking to expand its existing exports, but new LNG projects in Nigeria, Norway and Venezuela in particular are aimed at the US market. The purpose of this report is to describe the current status and potential development of LNG imports to the US with a view to identifying those circumstances in which an electric utility might consider LNG as an alternate back-up fuel to distillate or residual oil, in gas-fired generating facilities. 9 figs., 10 tabs.

Comparison of AEO 2006 Natural Gas Price Forecast to NYMEX FuturesPrices  

SciTech Connect

On December 12, 2005, the reference case projections from ''Annual Energy Outlook 2006'' (AEO 2006) were posted on the Energy Information Administration's (EIA) web site. We at LBNL have in the past compared the EIA's reference case long-term natural gas price forecasts from the AEO series to contemporaneous natural gas prices that can be locked in through the forward market, with the goal of better understanding fuel price risk and the role that renewables play in mitigating such risk (see, for example, http://eetd.lbl.gov/ea/EMS/reports/53587.pdf or http://eetd.lbl.gov/ea/ems/reports/54751.pdf). As such, we were curious to see how the latest AEO gas price forecast compares to the NYMEX natural gas futures strip. This brief memo presents our findings. As a refresher, our past work in this area has found that over the past five years, forward natural gas contracts (with prices that can be locked in--e.g., gas futures, swaps, and physical supply) have traded at a premium relative to contemporaneous long-term reference case gas price forecasts from the EIA. As such, we have concluded that, over the past five years at least, levelized cost comparisons of fixed-price renewable generation with variable price gas-fired generation that have been based on AEO natural gas price forecasts (rather than forward prices) have yielded results that are ''biased'' in favor of gas-fired generation, presuming that long-term price stability is valued. In this memo we simply update our past analysis to include the latest long-term gas price forecast from the EIA, as contained in AEO 2006. For the sake of brevity, we do not rehash information (on methodology, potential explanations for the premiums, etc.) contained in our earlier reports on this topic; readers interested in such information are encouraged to download that work from http://eetd.lbl.gov/ea/EMS/reports/53587.pdf or http://eetd.lbl.gov/ea/ems/reports/54751.pdf. As was the case in the past five AEO releases (AEO 2001-AEO 2005), we once again find that the AEO 2006 reference case gas price forecast falls well below where NYMEX natural gas futures contracts were trading at the time the EIA finalized its gas price forecast. In fact, the NYMEX-AEO 2006 reference case comparison yields by far the largest premium--$2.3/MMBtu levelized over five years--that we have seen over the last six years. In other words, on average, one would have had to pay $2.3/MMBtu more than the AEO 2006 reference case natural gas price forecast in order to lock in natural gas prices over the coming five years and thereby replicate the price stability provided intrinsically by fixed-price renewable generation (or other forms of generation whose costs are not tied to the price of natural gas). Fixed-price generation (like certain forms of renewable generation) obviously need not bear this added cost, and moreover can provide price stability for terms well in excess of five years.

Final Environmental Impact Statement Plymouth Generating Facility Plymouth, Washington  

SciTech Connect

Plymouth Energy, L.L.C. (Plymouth Energy) proposes to construct and operate the Plymouth Generating Facility (PGF), which would be a 307-megawatt (MW) natural gas-fired, combined cycle power generation facility on a 44.5-acre site 2 miles west of the rural community of Plymouth in southern Benton County, Washington. Plymouth Energy has proposed that the PGF would be interconnected to the Bonneville Power Administration's (BPA's) proposed McNary-John Day 500-kilovolt (kV) transmission line at a point approximately 4.7 miles west of BPA's McNary Substation. This tie-in to the McNary-John Day line would be approximately 0.6 mile to the north of the project site. Natural gas would be supplied to the project by an 800-foot pipeline lateral from the Williams Northwest Gas Pipeline Company (Williams Co.) Plymouth Compressor Station, which is located adjacent to the plant site. Water for project use would be supplied from a groundwater well whose perfected rights have been transferred to the project. A small additional quantity of water to meet plant peak needs would be obtained by lease from the neighboring farm operation. Wastewater resulting from project operations would be supplied to the neighboring farm for blending with farm-supplied water, and then used for crop irrigation. Electricity generated by the PGF would be delivered to the BPA electric grid via a new transmission interconnection for transmission of energy to regional purchasers of electricity.

Comparative life-cycle air emissions of coal, domestic natural gas, LNG, and SNG for electricity generation  

SciTech Connect

The U.S. Department of Energy (DOE) estimates that in the coming decades the United States' natural gas (NG) demand for electricity generation will increase. Estimates also suggest that NG supply will increasingly come from imported liquefied natural gas (LNG). Additional supplies of NG could come domestically from the production of synthetic natural gas (SNG) via coal gasification-methanation. The objective of this study is to compare greenhouse gas (GHG), SOx, and NOx life-cycle emissions of electricity generated with NG/LNG/SNG and coal. This life-cycle comparison of air emissions from different fuels can help us better understand the advantages and disadvantages of using coal versus globally sourced NG for electricity generation. Our estimates suggest that with the current fleet of power plants, a mix of domestic NG, LNG, and SNG would have lower GHG emissions than coal. If advanced technologies with carbon capture and sequestration (CCS) are used, however, coal and a mix of domestic NG, LNG, and SNG would have very similar life-cycle GHG emissions. For SOx and NOx we find there are significant emissions in the upstream stages of the NG/LNG life-cycles, which contribute to a larger range in SOx and NOx emissions for NG/LNG than for coal and SNG. 38 refs., 3 figs., 2 tabs.

Development of the next generation medium-duty natural gas engine  

DOE Green Energy (OSTI)

This report summarizes the work done under this subcontract in the areas of System Design, System Fabrication, and Experimental Program. The report contains the details of the engine development process for achieving throttleless stratified charge spark ignition (SI) engine operation as well as advanced turbocharging strategies. Engine test results showing the potential of the direct-injection stratified charge combustion strategy for increasing part-load engine efficiency on a John Deere 8.1-liter natural gas engine are also included in this report. In addition, steady state and step transient engine data are presented that quantify the performance of a variable geometry turbocharger (VGT) as well as a modified waste-gated turbocharger on the engine. The benefits of the technologies investigated during this project will be realized in the form of increased drive-cycle efficiency to diesel-like levels, while retaining the low emissions characteristics of a lean-burn natural gas engine.

PV output smoothing using a battery and natural gas engine-generator.  

SciTech Connect

In some situations involving weak grids or high penetration scenarios, the variability of photovoltaic systems can affect the local electrical grid. In order to mitigate destabilizing effects of power fluctuations, an energy storage device or other controllable generation or load can be used. This paper describes the development of a controller for coordinated operation of a small gas engine-generator set (genset) and a battery for smoothing PV plant output. There are a number of benefits derived from using a traditional generation resource in combination with the battery; the variability of the photovoltaic system can be reduced to a specific level with a smaller battery and Power Conditioning System (PCS) and the lifetime of the battery can be extended. The controller was designed specifically for a PV/energy storage project (Prosperity) and a gas engine-generator (Mesa Del Sol) currently operating on the same feeder in Albuquerque, New Mexico. A number of smoothing simulations of the Prosperity PV were conducted using power data collected from the site. By adjusting the control parameters, tradeoffs between battery use and ramp rates could be tuned. A cost function was created to optimize the control in order to balance, in this example, the need to have low ramp rates with reducing battery size and operation. Simulations were performed for cases with only a genset or battery, and with and without coordinated control between the genset and battery, e.g., without the communication link between sites or during a communication failure. The degree of smoothing without coordinated control did not change significantly because the battery dominated the smoothing response. It is anticipated that this work will be followed by a field demonstration in the near future.

Limited Electricity Generation Supply and Limited Natural Gas Supply Cases (released in AEO2008)  

Reports and Publications (EIA)

Development of U.S. energy resources and the permitting and construction of large energy facilities have become increasingly difficult over the past 20 years, and they could become even more difficult in the future. Growing public concern about global warming and CO2 emissions also casts doubt on future consumption of fossil fuelsparticularly coal, which releases the largest amount of CO2 per unit of energy produced. Even without regulations to limit greenhouse gas emissions in the United States, the investment community may already be limiting the future use of some energy options. In addition, there is considerable uncertainty about the future availability of, and access to, both domestic and foreign natural gas resources.

Comparison of AEO 2005 natural gas price forecast to NYMEX futures prices  

SciTech Connect

On December 9, the reference case projections from ''Annual Energy Outlook 2005 (AEO 2005)'' were posted on the Energy Information Administration's (EIA) web site. As some of you may be aware, we at LBNL have in the past compared the EIA's reference case long-term natural gas price forecasts from the AEO series to contemporaneous natural gas prices that can be locked in through the forward market, with the goal of better understanding fuel price risk and the role that renewables play in mitigating such risk. As such, we were curious to see how the latest AEO gas price forecast compares to the NYMEX natural gas futures strip. This brief memo presents our findings. As a refresher, our past work in this area has found that over the past four years, forward natural gas contracts (e.g., gas futures, swaps, and physical supply) have traded at a premium relative to contemporaneous long-term reference case gas price forecasts from the EIA. As such, we have concluded that, over the past four years at least, levelized cost comparisons of fixed-price renewable generation with variable price gas-fired generation that have been based on AEO natural gas price forecasts (rather than forward prices) have yielded results that are ''biased'' in favor of gas-fired generation (presuming that long-term price stability is valued). In this memo we simply update our past analysis to include the latest long-term gas price forecast from the EIA, as contained in AEO 2005. For the sake of brevity, we do not rehash information (on methodology, potential explanations for the premiums, etc.) contained in our earlier reports on this topic; readers interested in such information are encouraged to download that work from http://eetd.lbl.gov/ea/EMS/reports/53587.pdf or, more recently (and briefly), http://eetd.lbl.gov/ea/ems/reports/54751.pdf. As was the case in the past four AEO releases (AEO 2001-AE0 2004), we once again find that the AEO 2005 reference case gas price forecast falls well below where NYMEX natural gas futures contracts were trading at the time the EIA finalized its gas price forecast. In fact, the NYMEXAEO 2005 reference case comparison yields by far the largest premium--$1.11/MMBtu levelized over six years--that we have seen over the last five years. In other words, on average, one would have to pay $1.11/MMBtu more than the AEO 2005 reference case natural gas price forecast in order to lock in natural gas prices over the coming six years and thereby replicate the price stability provided intrinsically by fixed-price renewable generation. Fixed-price renewables obviously need not bear this added cost, and moreover can provide price stability for terms well in excess of six years.

Assessing the Potential of Natural Microbial Communities to Improve a Second-Generation Biofuels Platform  

E-Print Network (OSTI)

Naturally occurring microbial communities from high-salt and/or high-temperature environments were collected from sites across the United States and Puerto Rico and screened for their efficacy in the MixAlco biofuel production platform. The MixAlco process, based on the carboxylate platform, is a sustainable and economically viable platform for converting lignocellulosic biomass to biofuels. Using a mixed culture of anaerobic organisms, lignocellulosic biomass is fermented into carboxylic acids, which are neutralized to their corresponding carboxylate salts. These salts can then be converted into a wide variety of chemical products and fuels (alcohols, gasoline, diesel, jet fuel). The central hypothesis is that microbial communities from relatively extreme environments, having evolved to withstand selection pressures similar to the conditions in the carboxylate platform, will exhibit high rates of biomass conversion. A total of 559 soil communities was screened as inocula in established laboratory-scale fermentations. We used pyrotag sequencing of 16S rRNA genes to characterize the bacterial components of the best-performing microbial communities. The best performing communities converted up to 3 times more biomass to acids than a standard marine community inoculum. The community analyses have allowed us to determine the extent to which the same functional types are favored during fermentation, at both laboratory and demonstration plant scales. In all cases, we observed a shift from the more diverse sediment community to post-fermentation communities with relatively low diversity dominated by organisms in the phylum Firmicutes, specifically Bacilli and Clostridia classes. Despite the fact that the inoculum sources were both geographically and ecologically diverse, all of the post-fermentation communities were more similar to each other in community structure than to the corresponding original inoculum community. In addition, studies of the sediments used as inocula revealed that environmental parameters, such as pH and water content, were significantly correlated with bacterial community composition. The wealth of data provided by current sequencing technologies allowed us to question whether communities with high process performances tend to achieve that performance with similar community structures.

Thermal energy storage for coal-fired power generation  

DOE Green Energy (OSTI)

This paper presents an engineering and economic evaluation of using thermal energy storage (TES) with coal-fired conventional and combined cycle power plants. In the first case, conventional pulverized coal combustion equipment was assumed to continuously operate to heat molten nitrate salt which was then stored in a tank. During intermediate-load demand periods, hot salt was withdrawn from storage and used to generate steam for a Rankine steam power cycle. This allowed the coal-fired salt heater to be approximately one-third the size of a coal-fired boiler in a conventional cycling plant. The use of nitrate salt TES also reduced the levelized cost of power by between 5% and 24% depends on the operating schedule. The second case evaluate the use of thermal energy storage with an integrated gasification combined cycle (IGCC) power plant. In this concept, the nitrate salt was heated by a combination of the gas turbine exhaust and the hot fuel gas. The IGCC plant also contained a low-temperature storage unit that uses a mixture of oil and rock as the thermal storage medium. Thermal energy stored in the low-temperature TES was used to preheat the feedwater after it leaves the condenser and to produce process steam for other applications in the IGCC plant. This concept study also predicted a 5% to 20% reduction in levelized cost of power compared to other coal-fired alternatives. If significant escalation rates in the price of fuel were assumed, the concept could be competitive with natural-gas-fired intermediate-load power generation. A sensitivity analysis of using a direct-contact heat exchanger instead of the conventional finned-tube design showed a significant reduction in the installed capital cost. 3 refs., 2 figs., 6 tabs.

Staff Draft Report. Comparative Cost of California Central Station Electricity Generation Technologies.  

DOE Green Energy (OSTI)

This Energy Commission staff draft report presents preliminary levelized cost estimates for several generic central-station electricity generation technologies. California has traditionally adopted energy policies that balance the goals of supporting economic development, improving environmental quality and promoting resource diversity. In order to be effective, such policies must be based on comprehensive and timely gathering of information. With this goal in mind, the purpose of the report is to provide comparative levelized cost estimates for a set of renewable (e.g., solar) and nonrenewable (e.g., natural gas-fired) central-station electricity generation resources, based on each technology's operation and capital cost. Decision-makers and others can use this information to compare the generic cost to build specific technology. These costs are not site specific. If a developer builds a specific power plant at a specific location, the cost of siting that plant at that specific location must be considered. The Energy Commission staff also identifies the type of fuel used by each technology and a description of the manner in which the technology operates in the generation system. The target audiences of this report are both policy-makers and anyone wishing to understand some of the fundamental attributes that are generally considered when evaluating the cost of building and operating different electricity generation technology resources. These costs do not reflect the total cost to consumers of adding these technologies to a resources portfolio. These technology characterizations do not capture all of the system, environmental or other relevant attributes that would typically be needed by a portfolio manager to conduct a comprehensive ''comparative value analysis''. A portfolio analysis will vary depending on the particular criteria and measurement goals of each study. For example, some form of firm capacity is typically needed with wind generation to support system reliability. [DJE-2005

Comparing Statewide Economic Impacts of New Generation from Wind, Coal, and Natural Gas in Arizona, Colorado, and Michigan  

SciTech Connect

With increasing concerns about energy independence, job outsourcing, and risks of global climate change, it is important for policy makers to understand all impacts from their decisions about energy resources. This paper assesses one aspect of the impacts: direct economic effects. The paper compares impacts to states from equivalent new electrical generation from wind, natural gas, and coal. Economic impacts include materials and labor for construction, operations, maintenance, fuel extraction, and fuel transport, as well as project financing, property tax, and landowner revenues. We examine spending on plant construction during construction years, in addition to all other operational expenditures over a 20-year span. Initial results indicate that adding new wind power can be more economically effective than adding new gas or coal power and that a higher percentage of dollars spent on coal and gas will leave the state. For this report, we interviewed industry representatives and energy experts, in addition to consulting government documents, models, and existing literature. The methodology for this research can be adapted to other contexts for determining economic effects of new power generation in other states and regions.

Evaluation of Reformer Produced Synthesis Gas for Emissions Reductions in Natural Gas Reciprocating Engines  

DOE Green Energy (OSTI)

Rolls-Royce Fuel Cell Systems (US) Inc. (RRFCS) has developed a system that produces synthesis gas from air and natural gas. A near-term application being considered for this technology is synthesis gas injection into reciprocating engines for reducing NOx emissions. A proof of concept study using bottled synthesis gas and a two-stroke reciprocating engine showed that injecting small amounts of highflammables content synthesis gas significantly improved combustion stability and enabled leaner engine operation resulting in over 44% reduction in NOx emissions. The actual NOx reduction that could be achieved in the field is expected to be engine specific, and in many cases may be even greater. RRFCS demonstrated that its synthesis gas generator could produce synthesis gas with the flammables content that was successfully used in the engine testing. An economic analysis of the synthesis gas approach estimates that its initial capital cost and yearly operating cost are less than half that of a competing NOx reduction technology, Selective Catalytic Reduction. The next step in developing the technology is an integrated test of the synthesis gas generator with an engine to obtain reliability data for system components and to confirm operating cost. RRFCS is actively pursuing opportunities to perform the integrated test. A successful integrated test would demonstrate the technology as a low-cost option to reduce NOx emissions from approximately 6,000 existing two-stroke, natural gas-fired reciprocating engines used on natural gas pipelines in North America. NOx emissions reduction made possible at a reasonable price by this synthesis gas technology, if implemented on 25% of these engines, would be on the order of 25,000 tons/year.

Topical report: Natural convection shutdown heat removal test facility (NSTF) evaluation for generating additional reactor cavity cooling system (RCCS) data.  

DOE Green Energy (OSTI)

As part of the Department of Energy (DOE) Generation IV roadmapping activity, the Very High Temperature gas cooled Reactor (VHTR) has been selected as the principal concept for hydrogen production and other process-heat applications such as district heating and potable water production. On this basis, the DOE has selected the VHTR for additional R&D with the ultimate goal of demonstrating emission-free electricity and hydrogen production with this advanced reactor concept. One of the key passive safety features of the VHTR is the potential for decay heat removal by natural circulation of air in a Reactor Cavity Cooling System (RCCS). The air-cooled RCCS concept is notably similar to the Reactor Vessel Auxiliary Cooling System (RVACS) that was developed for the General Electric PRISM sodium-cooled fast reactor. As part of the DOE R&D program that supported the development of this fast reactor concept, the Natural Convection Shutdown Heat Removal Test Facility (NSTF) was developed at ANL to provide proof-of-concept data for the RVACS under prototypic natural convection flow, temperature, and heat flux conditions. Due to the similarity between RVACS and the RCCS, current VHTR R&D plans call for the utilization of the NSTF to provide RCCS model development and validation data, in addition to supporting design validation and optimization activities. Both air-cooled and water-cooled RCCS designs are to be included. In support of this effort, ANL has been tasked with the development of an engineering plan for mechanical and instrumentation modifications to NSTF to ensure that sufficiently detailed temperature, heat flux, velocity and turbulence profiles are obtained to adequately qualify the codes under the expected range of air-cooled RCCS flow conditions. Next year, similar work will be carried out for the alternative option of a water-cooled RCCS design. Analysis activities carried out in support of this experiment planning task have shown that: (a) in the RCCS, strong 3-D effects result in large heat flux, temperature, and heat transfer variations around the tube wall; (b) there is a large difference in the heat transfer coefficient predicted by turbulence models and heat transfer correlations, and this underscores the need of experimental work to validate the thermal performance of the RCCS; and (c) tests at the NSTF would embody all important fluid flow and heat transfer phenomena in the RCCS, in addition to covering the entire parameter ranges that characterize these phenomena. Additional supporting scaling study results are available in Reference 2. The purpose of this work is to develop a high-level engineering plan for mechanical and instrumentation modifications to NSTF in order to meet the following two technical objectives: (1) provide CFD and system-level code development and validation data for the RCCS under prototypic (full-scale) natural convection flow conditions, and (2) support RCCS design validation and optimization. As background for this work, the report begins by providing a summary of the original NSTF design and operational capabilities. Since the facility has not been actively utilized since the early 1990's, the next step is to assess the current facility status. With this background material in place, the data needs and requirements for the facility are then defined on the basis of supporting analysis activities. With the requirements for the facility established, appropriate mechanical and instrumentation modifications to NSTF are then developed in order to meet the overall project objectives. A cost and schedule for modifying the facility to satisfy the RCCS data needs is then provided.

Development of a high-performance coal-fired power generating system with pyrolysis gas and char-fired high temperature furnace (HITAF)  

SciTech Connect

A concept for an advanced coal-fired combined-cycle power generating system is currently being developed. The first phase of this three-phase program consists of conducting the necessary research and development to define the system, evaluate the economic and technical feasibility of the concept, and prepare an R D plan to develop the concept further. Foster Wheeler Development Corporation is leading a team ofcompanies involved in this effort. The system proposed to meet these goals is a combined-cycle system where air for a gas turbine is indirectly heated to approximately 1800[degrees]F in furnaces fired with cool-derived fuels and then directly heated in a natural-gas-fired combustor up to about 2400[degrees]F. The system is based on a pyrolyzing process that converts the coal into a low-Btu fuel gas and char. The fuelgas is a relatively clean fuel, and it is fired to heat tube surfaces that are susceptible to corrosion and problems from ash deposition. In particular, the high-temperature air heater tubes, which will need tobe a ceramic material, will be located in a separate furnace or region of a furnace that is exposed to combustion products from the low-Btu fuel gas only. A simplified process flow diagram is shown.

Although the electric-only effciency of DG is lower than that of central-station production, relatively high tariff rates and the potential for CHP applications increase the attractiveness of on-site generation.

The Nature of Microjansky Radio Sources and Implications for the Design of the Next Generation Very Sensitive Radio Telescopes  

E-Print Network (OSTI)

Deep radio surveys show a population of very red counterparts of microjansky radio sources, which are unidentified to I = 25 in ground based images and I = 28.5 in the Hubble Deep Field. This population of optically faint radio sources, which comprises about 20% of the microjansky radio samples, may be dust enshrouded starburst galaxies, extreme redshift or dust reddened AGN, or due to displaced radio lobes. Even deeper radio surveys, which will be made possible by next generation radio telescopes such as the Expanded VLA or the Square Kilometer Array, will reach to nanojansky levels which may be dominated by this new population, but only if special care is taken to achieve high angular resolution and dynamic range better than 60 dB. This will reuire array dimensions up to 1000 km to achieve confusion limited performance at 1.4 GHz and up to 10,000 km at 300 MHz. But, even then, the ability to study individual nanojanksy radio sources may be limited by the finite extent of the sources and consequential blending of their images.

Hanford Generating Project (HGP) Repowering Analysis.  

Science Conference Proceedings (OSTI)

The Hanford Generating Project (HGP), owned by the Washington Public Power Supply System, consists of two low pressure steam turbines, generators, and associated equipment located adjacent to the Department of Energy's (DOE) N-Reactor. HGP has been able to produce approximately 800 MWe with low pressure steam supplied by N-Reactor. DOE has placed N-Reactor in cold standby status for an undetermined length of time. This results in the idling of the HGP since no alternative source of steam is available. Bonneville Power Administration contracted with Fluor Daniel, Inc. to investigate the feasibility and cost of constructing a new source of steam for (repowering) one of the HGP turbines. The steam turbine is currently operated with 135 psia steam. The turbines can be rebuilt to operate with 500 psia steam pressure by adding additional stages, buckets, nozzles, and diaphragms. Because of the low pressure design, this turbine can never achieve the efficiencies possible in new high pressure turbines by the presences of existing equipment reduces the capital cost of a new generating resource. Five repowering options were investigated in this study. Three cases utilizing gas turbine combined cycle steam generation equipment, one case utilizing a gas fired boiler, and a case utilizing a coal fired boiler. This report presents Fluor Daniel's analysis of these repowering options.

Dampers for Natural Draft Heaters: Technical Report  

Science Conference Proceedings (OSTI)

Energy required for water heating accounts for approximately 40percent of national residential natural gas consumption in California. With water heating contributing such a substantial portion of natural gas consumption, it is important to pay attention to water heater efficiencies. This paper reports on an investigation of a patented, buoyancy-operated flue damper. It is an add-on design to a standard atmospherically vented natural-draft gas-fired storage water heater. The flue damper was expected to reduce off-cycle standby losses, which would lead to improvements in the efficiency of the water heater. The test results showed that the Energy Factor of the baseline water heater was 0.576. The recovery efficiency was 0.768. The standby heat loss coefficient was 10.619 (BTU/hr-oF). After the damper was installed, the test results show an Energy Factor for the baseline water heater of 0.605. The recovery efficiency was 0.786. The standby heat loss coefficient was 9.135 (BTU/hr-oF). The recovery efficiency increased 2.3percent and the standby heat loss coefficient decreased 14percent. When the burner was on, the baseline water heater caused 28.0 CFM of air to flow from the room. During standby, the flow was 12.4 CFM. The addition of the damper reduced the flow when the burner was on to 23.5 CFM. During standby, flow with the damper was reduced to 11.1 CFM. The flue damper reduced off-cycle standby losses, and improved the efficiency of the water heater. The flue damper also improved the recovery efficiency of the water heater by restricting on-cycle air flows through the flue.With or without the flue damper, off-cycle air flow upthe stack is nearly half the air flow rate as when the burner is firing.

The Next Generation Turbine (NGT) Program's technological development focused on a study of the feasibility of turbine systems greater than 30 MW that offer improvement over the 1999 state-of-the-art systems. This program targeted goals of 50 percent turndown ratios, 15 percent reduction in generation cost/kW hour, improved service life, reduced emissions, 400 starts/year with 10 minutes to full load, and multiple fuel usage. Improvement in reliability, availability, and maintainability (RAM), while reducing operations, maintenance, and capital costs by 15 percent, was pursued. This program builds on the extensive low emissions stationary gas turbine work being carried out by Pratt & Whitney (P&W) for P&W Power Systems (PWPS), which is a company under the auspices of the United Technologies Corporation (UTC). This study was part of the overall Department of Energy (DOE) NGT Program that extends out to the year 2008. A follow-on plan for further full-scale component hardware testing is conceptualized for years 2002 through 2008 to insure a smooth and efficient transition to the marketplace for advanced turbine design and cycle technology. This program teamed the National Energy Technology Laboratory (NETL), P&W, United Technologies Research Center (UTRC), kraftWork Systems Inc., a subcontractor on-site at UTRC, and Multiphase Power and Processing Technologies (MPPT), an off-site subcontractor. Under the auspices of the NGT Program, a series of analyses were performed to identify the NGT engine system's ability to serve multiple uses. The majority were in conjunction with a coal-fired plant, or used coal as the system fuel. Identified also was the ability of the NGT system to serve as the basis of an advanced performance cycle: the humid air turbine (HAT) cycle. The HAT cycle is also used with coal gasification in an integrated cycle HAT (IGHAT). The NGT systems identified were: (1) Feedwater heating retrofit to an existing coal-fired steam plant, which could supply both heat and peaking power (Block 2 engine); (2) Repowering of an older coal-fired plant (Block 2 engine); (3) Gas-fired HAT cycle (Block 1 and 2 engines); (4) Integrated gasification HAT (Block 1 and 2 engines). Also under Phase I of the NGT Program, a conceptual design of the combustion system has been completed. An integrated approach to cycle optimization for improved combustor turndown capability has been employed. The configuration selected has the potential for achieving single digit NO{sub x}/CO emissions between 40 percent and 100 percent load conditions. A technology maturation plan for the combustion system has been proposed. Also, as a result of Phase I, ceramic vane technology will be incorporated into NGT designs and will require less cooling flow than conventional metallic vanes, thereby improving engine efficiency. A common 50 Hz and 60 Hz power turbine was selected due to the cost savings from eliminating a gearbox. A list of ceramic vane technologies has been identified for which the funding comes from DOE, NASA, the U.S. Air Force, and P&W.

Competitive position of natural gas: Industrial baking  

SciTech Connect

Industrial baking is one of the largest natural gas consumers in the food industry. In 1985, bread, rolls, cookies, and crackers accounted for over 82 percent of all baked goods production. Bread accounting for 46 percent of all production. The baking industry consumed approximately 16 trillion Btu in 1985. About 93 percent was natural gas, while distillate fuel oil accounted for seven percent, and electricity accounted for much less than one percent. The three main types of baking ovens are the single lap, tunnel, and Lanham ovens. In the single lap oven, trays carry the product back and forth through the baking chamber once. The single lap oven is the most common type of oven and is popular due to its long horizontal runs, extensive steam zone, and simple construction. The tunnel oven is slightly more efficient and more expensive that the single lap oven. IN the tunnel oven, the hearth is a motorized conveyor which passes in a straight line through a series of heating zones, with loading and unloading occurring at opposite ends of the oven. The advantages of the tunnel oven include flexibility with respect to pan size and simple, accurate top and bottom heat control. The tunnel oven is used exclusively in the cookie and cracker baking, with the product being deposited directly on the oven band. The most recently developed type of oven is the Lanham oven. The Lanham oven is the most efficient type of oven, with a per pound energy consumption approaching the practical minimum for baking bread. Between one--half and two--thirds of all new industrial baking ovens are Lanham ovens. In the Lanham oven, the product enters the oven near the top of the chamber, spirals down through a series of heating zones, and exits near the bottom of the oven. The oven is gas--fired directly by ribbon burners. 31 refs.

Don`t overlook natural gas cooling equipment  

Science Conference Proceedings (OSTI)

If one thought the confusion surrounding chiller specification and operation ended with the availability of CFC-free refrigerant alternatives, think again. Plant engineers involved in the selection and installation of cooling equipment are facing yet another complicated task, this time thanks to deregulation of the electric utility industry. Still in its early stages, deregulation is a process that could take up to a decade. However, deregulation is also bringing about changing pricing structures. Electric power costs may not always be low for everyone. For plants paying $0.02/kwh for electricity, an electric-powered chiller is a must. But those paying $0.35 or $0.40/kwh, even for a few hours, cannot afford NOT to consider something besides an electric-motor-driven chiller. Among the most viable, yet often overlooked, options available is natural gas cooling. Gas cooling equipment gives industrial users the flexibility to choose either gas or electricity to drive their cooling systems. Natural gas cooling is defined here as the use of absorption cooling systems and engine-driven chillers, as alternatives to electric-driven equipment, to deliver chilled water in a conventional manner. Desiccant systems can also be gas fired and are used primarily for providing dry air for process control. Because of their specialized applications, desiccant cooling is not covered in this article.

GE power generation technology challenges for advanced gas turbines  

SciTech Connect

The GE Utility ATS is a large gas turbine, derived from proven GEPG designs and integrated GEAE technology, that utilizes a new turbine cooling system and incorporates advanced materials. This system has the potential to achieve ATS objectives for a utility sized machine. Combined with use of advanced Thermal Barrier Coatings (TBC`s), the new cooling system will allow higher firing temperatures and improved cycle efficiency that represents a significant improvement over currently available machines. Developing advances in gas turbine efficiency and emissions is an ongoing process at GEPG. The third generation, ``F`` class, of utility gas turbines offers net combined cycle efficiencies in the 55% range, with NO{sub x} programs in place to reduce emissions to less than 10 ppM. The gas turbines have firing temperatures of 2350{degree}F, and pressure ratios of 15 to 1. The turbine components are cooled by air extracted from the cycle at various stages of the compressor. The heat recovery cycle is a three pressure steam system, with reheat. Throttle conditions are nominally 1400 psi and 1000{degree}F reheat. As part of GEPG`s ongoing advanced power generation system development program, it is expected that a gas fired advanced turbine system providing 300 MW power output greater than 58% net efficiency and < 10 ppM NO{sub x} will be defined. The new turbine cooling system developed with technology support from the ATS program will achieve system net efficiency levels in excess of 60%.

Development of a Hydrogasification Process for Co-Production of Substitute Natural Gas (SNG) and Electric Power from Western Coals-Phase I  

DOE Green Energy (OSTI)

The Advanced Hydrogasification Process (AHP)--conversion of coal to methane--is being developed through NETL with a DOE Grant and has successfully completed its first phase of development. The results so far are encouraging and have led to commitment by DOE/NETL to begin a second phase--bench scale reactor vessel testing, expanded engineering analysis and economic perspective review. During the next decade new means of generating electricity, and other forms of energy, will be introduced. The members of the AHP Team envision a need for expanded sources of natural gas or substitutes for natural gas, to fuel power generating plants. The initial work the team has completed on a process to use hydrogen to convert coal to methane (pipeline ready gas) shows promising potential. The Team has intentionally slanted its efforts toward the needs of US electric utilities, particularly on fuels that can be used near urban centers where the greatest need for new electric generation is found. The process, as it has evolved, would produce methane from coal by adding hydrogen. The process appears to be efficient using western coals for conversion to a highly sought after fuel with significantly reduced CO{sub 2} emissions. Utilities have a natural interest in the preservation of their industry, which will require a dramatic reduction in stack emissions and an increase in sustainable technologies. Utilities tend to rank long-term stable supplies of fuel higher than most industries and are willing to trade some ratio of cost for stability. The need for sustainability, stability and environmentally compatible production are key drivers in the formation and progression of the AHP development. In Phase II, the team will add a focus on water conservation to determine how the basic gasification process can be best integrated with all the plant components to minimize water consumption during SNG production. The process allows for several CO{sub 2} reduction options including consumption of the CO{sub 2} in the original process as converted to methane. The process could under another option avoid emissions following the conversion to SNG through an adjunct algae conversion process. The algae would then be converted to fuels or other products. An additional application of the algae process at the end use natural gas fired plant could further reduce emissions. The APS team fully recognizes the competition facing the process from natural gas and imported liquid natural gas. While we expect those resources to set the price for methane in the near-term, the team's work to date indicates that the AHP process can be commercially competitive, with the added benefit of assuring long-term energy supplies from North American resources. Conversion of coal to a more readily transportable fuel that can be employed near load centers with an overall reduction of greenhouses gases is edging closer to reality.

Heat generation in natural gas adsorption systems  

SciTech Connect

Experiments were conducted using a high-surface-area carbon as an adsorbent for methane to determine the impact of the heat of adsorption upon the storage capacity. The rapid filling of an adsorption storage system under conditions in which the heat of adsorption is not dissipated results in only about 75% of the methane being stored at 3.44 MPa (500 psia) as can be stored by a slow fill rate with heat dissipation. These results depend upon the initial temperature of the absorbent bed and upon the characteristics of the substrate itself. 4 refs., 5 figs.

Mapping Study to Characterize NSCR Performance on a Natural Gas-Fueled Engine Mapping Study to Characterize NSCR Performance on a Natural Gas-Fueled Engine Mapping Study to Characterize NSCR Performance on a Natural Gas-Fueled Engine Authors: Mohamed Toema (speaker), Sarah Nuss-Warren, and Kirby S. Chapman, Kansas State University National Gas Machinery Laboratory; James McCarthy and Thomas McGrath, Innovative Environmental Solutions Inc. Venue: ASME Internal Combustion Engine Division 2009 Spring Technical Conference, May 3–6, Milwaukee, WI. http://www.asmeconferences.org/ICES09/index.cfm [external site]. Abstract: The researchers are conducting a project to characterize pollutant emissions performance of field gas-fired four-stroke cycle rich burn engines equipped with non-selective catalytic reduction (NSCR) technology. Engine emissions and operating parameters are being monitored on three engines over an extended period. In addition, a mapping study was conducted on one engine. The NSCR was operated at various controlled air-to-fuel (AF) ratios while emission measurements were conducted and engine operating parameters monitored. NOx, CO, and oxygen were measured using both EPA reference method technology and the portable analyzer used in the long-term study. In the mapping study, ammonia, formaldehyde, CO, NOx, and speciated hydrocarbon emissions were recorded in real-time using an extractive FTIR system. This paper focuses on the engine mapping phase. The mapping tests demonstrated a trade-off between NOx emissions and CO, ammonia, and hydrocarbon emissions. Richer engine operation (lower AF) decreases NOx emissions at the expense of higher CO, ammonia, and hydrocarbons. Leaner operation has the opposite effect. The results to date of the semi-continuous monitoring are presented in a separate paper.

Flashback Detection Sensor for Hydrogen Augmented Natural Gas Combustion  

DOE Green Energy (OSTI)

The use of hydrogen augmented fuel is being investigated by various researchers as a method to extend the lean operating limit, and potentially reduce thermal NOx formation in natural gas fired lean premixed (LPM) combustion systems. The resulting increase in flame speed during hydrogen augmentation, however, increases the propensity for flashback in LPM systems. Real-time in-situ monitoring of flashback is important for the development of control strategies for use of hydrogen augmented fuel in state-of-the-art combustion systems, and for the development of advanced hydrogen combustion systems. The National Energy Technology Laboratory (NETL) and Woodward Industrial Controls are developing a combustion control and diagnostics sensor (CCADS), which has already been demonstrated as a useful sensor for in-situ monitoring of natural gas combustion, including detection of important combustion events such as flashback and lean blowoff. Since CCADS is a flame ionization sensor technique, the low ion concentration produced in pure hydrogen combustion raises concerns of whether CCADS can be used to monitor flashback in hydrogen augmented combustion. This paper discusses CCADS tests conducted at 0.2-0.6 MPa (2-6 atm), demonstrating flashback detection with fuel compositions up to 80% hydrogen (by volume) mixed with natural gas. NETL’s Simulation Validation (SimVal) combustor offers full optical access to pressurized combustion during these tests. The CCADS data and high-speed video show the reaction zone moves upstream into the nozzle as the hydrogen fuel concentration increases, as is expected with the increased flame speed of the mixture. The CCADS data and video also demonstrate the opportunity for using CCADS to provide the necessary in-situ monitor to control flashback and lean blowoff in hydrogen augmented combustion applications.

Winning in electricity generation  

SciTech Connect

Should you be a buyer or a seller of generation? In general, spot buyers should do very well, while many generation owners will be fortunate to recover their stranded costs. Successful generators will capitalize on superior operating performance and market knowledge. The smartest natural gas strategy in the early 1980`s was to short natural gas. Will this lesson of restructuring be written again of the electricity generation business of the late 1990`s? The authors will examine whether and how winners might emerge in the generation business of the future. The U.S. electric generation market, already marked by intense competition for new capacity and industrial demand, will become even more competitive as it makes the transition from regulated local monopoly to marketbased commodity pricing. At risk is up to $150 billion of shareholder equity and the future viability of half of the country`s investor-owned utilities. The winners in year 2005 will be those who early on developed strategies that simultaneously recovered existing generation investments while restructuring their asset portfolios and repositioning their plants to compete in the new market. Losers will have spent the time mired in indecision, their strategies ultimately forced upon them by regulators or competitors.

The generation of HCl in the system NaCl-KCl-H{sub 2}O-quartz at 600{degrees}C: Implications regarding HCl in natural systems at lower temperatures  

SciTech Connect

In experiments at 600°C in the system NaCI-KCI-H2O, within the analytical uncertainty, stoichiometric quantities of Cl and total alkali metals (Na+K) appear to dissolve in steam coexisting with chloride-rich brine at high pressures in the absence of solid salt. In contrast, at lower pressures, where steam coexists with precipitated salts, significant excess chloride as associated hydrogen chloride (HCI°) dissolves in steam. The HCI° appears to be generated by the reaction of solid NaCl(s) (halite) with steam, producing solid NaOH(s) that diffuses into halite, forming a solid solution. Where HCI° is present highly associated NaOH° as well as associated NaCI° appear to dissolve in steam, and the solubility of each is increased as the mole fraction of NaOH(s) in halite increases. In our quasi-static experiments, compared to dynamic flow-through experiments of others, higher initial ratios of H2O/NaCI have resulted in higher mole fractions of NaOH(s) in solid solution in halite and, accordingly, higher solubilities of NaCI" and NaOH" dissolved in steam. Addition of quartz to the system NaCI-KCI-H2O results in the formation of sodium disilicate by reaction of silica with NaOH(s) and an order of magnitude increase in the concentration of HCl° dissolved in steam. In natural hydrothermal systems at lower temperatures where brine or brine plus steam are present in the absence of precipitated salt, the pH of the brine is controlled mainly by base exchange reactions involving a variety of silicates that fix Na+/H+ and K+/H+ activity ratios. Where feldspars are present pH values generally are near neutral. Where mica, but no feldspar is present pH values may become only moderately acid. High acidity in salt-absent brine systems occurs only where all feldspars and mica have been altered to other minerals (generally pyrophyllite/ kaolinite or alunite). The situation changes significantly when salt precipitates. Hydrolysis produces HCI° by the reaction of water with NaCl when halite is present. The NaOH(s) that is produced as a byproduct is likely to react with quartz plus various alumino-silicates, producing a variety of alteration products and allowing steam to become greatly enriched in HCl° compared to the composition of steam that is attained in the simple system NaCI-KCI-H2O with halite present. Also, when a natural high-temperature hydrothermal system changes from one in which the pore fluid is brine to one in which the pore fluid is dry steam there is a drastic change in Na+/H+ and K+/H+ activity ratios in the pore fluid because the hydrogen ions that were predominantly dissociated species in the brine become predominantly associated species in steam. The net result is the stabilization of alkali feldspars in contact with steam that may contain appreciable HCI° that is produced by the reaction of precipitated salt with the steam.

NATURAL GAS HYDRATES STORAGE PROJECT PHASE II. CONCEPTUAL DESIGN AND ECONOMIC STUDY  

SciTech Connect

DOE Contract DE-AC26-97FT33203 studied feasibility of utilizing the natural-gas storage property of gas hydrates, so abundantly demonstrated in nature, as an economical industrial process to allow expanded use of the clean-burning fuel in power plants. The laboratory work achieved breakthroughs: (1) Gas hydrates were found to form orders of magnitude faster in an unstirred system with surfactant-water micellar solutions. (2) Hydrate particles were found to self-pack by adsorption on cold metal surfaces from the micellar solutions. (3) Interstitial micellar-water of the packed particles were found to continue forming hydrates. (4) Aluminum surfaces were found to most actively collect the hydrate particles. These laboratory developments were the bases of a conceptual design for a large-scale process where simplification enhances economy. In the design, hydrates form, store, and decompose in the same tank in which gas is pressurized to 550 psi above unstirred micellar solution, chilled by a brine circulating through a bank of aluminum tubing in the tank employing gas-fired refrigeration. Hydrates form on aluminum plates suspended in the chilled micellar solution. A low-grade heat source, such as 110 F water of a power plant, circulates through the tubing bank to release stored gas. The design allows a formation/storage/decomposition cycle in a 24-hour period of 2,254,000 scf of natural gas; the capability of multiple cycles is an advantage of the process. The development costs and the user costs of storing natural gas in a scaled hydrate process were estimated to be competitive with conventional storage means if multiple cycles of hydrate storage were used. If more than 54 cycles/year were used, hydrate development costs per Mscf would be better than development costs of depleted reservoir storage; above 125 cycles/year, hydrate user costs would be lower than user costs of depleted reservoir storage.

Electricity and Natural Gas Efficiency Improvements for Residential Gas  

NLE Websites -- All DOE Office Websites (Extended Search)

and Natural Gas Efficiency Improvements for Residential Gas and Natural Gas Efficiency Improvements for Residential Gas Furnaces in the U.S. Title Electricity and Natural Gas Efficiency Improvements for Residential Gas Furnaces in the U.S. Publication Type Report LBNL Report Number LBNL-59745 Year of Publication 2006 Authors Lekov, Alexander B., Victor H. Franco, Stephen Meyers, James E. McMahon, Michael A. McNeil, and James D. Lutz Document Number LBNL-59745 Publisher Lawrence Berkeley National Laboratory City Berkeley Abstract This paper presents analysis of the life-cycle costs for individual households and the aggregate energy and economic impacts from potential energy efficiency improvements in U.S. residential furnaces. Most homes in the US are heated by a central furnace attached to ducts for distributing heated air and fueled by natural gas. Electricity consumption by a furnace blower is significant, comparable to the annual electricity consumption of a major appliance. Since the same blower unit is also used during the summer to circulate cooled air in centrally air conditioned homes, electricity savings occur year round. Estimates are provided of the potential electricity savings from more efficient fans and motors. Current regulations require new residential gas-fired furnaces (not including mobile home furnaces) to meet or exceed 78% annual fuel utilization efficiency (AFUE), but in fact nearly all furnaces sold are at 80% AFUE or higher. The possibilities for higher fuel efficiency fall into two groups: more efficient non-condensing furnaces (81% AFUE) and condensing furnaces (90-96% AFUE). There are also options to increase the efficiency of the furnace blower. This paper reports the projected national energy and economic impacts of requiring higher efficiency furnaces in the future. Energy savings vary with climate, with the result that condensing furnaces offer larger energy savings in colder climates. The range of impacts for a statistical sample of households and the percent of households with net savings in life cycle cost are shown. Gas furnaces are somewhat unusual in that the technology does not easily permit incremental change to the AFUE above 80%. Achieving significant energy savings requires use of condensing technology, which yields a large efficiency gain (to 90% or higher AFUE), but has a higher cost. With respect to electricity efficiency design options, the ECM has a negative effect on the average LCC. The current extra cost of this technology more than offsets the sizable electricity savings.

Effect of Energy Efficiency Standards on Natural Gas Prices  

Science Conference Proceedings (OSTI)

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 in its price as seen at the wellhead (Wiser 2007). The magnitude of the effect on price relative to the demand reduction, and the mechanism through which it occurs, is less well established. This report attempts to quantify the potential effects of reduced demand for natural gas in the residential sector, in response to the implementation of an energy efficiency standard for water heaters.

GENERATING CAPACITY  

E-Print Network (OSTI)

Evidence from the U.S. and some other countries indicates that organized wholesale markets for electrical energy and operating reserves do not provide adequate incentives to stimulate the proper quantity or mix of generating capacity consistent with mandatory reliability criteria. A large part of the problem can be associated with the failure of wholesale spot market prices for energy and operating reserves to rise to high enough levels during periods when generating capacity is fully utilized. Reforms to wholesale energy markets, the introduction of well-design forward capacity markets, and symmetrical treatment of demand response and generating capacity resources to respond to market and institutional imperfections are discussed. This policy reform program is compatible with improving the efficiency of spot wholesale electricity markets, the continued evolution of competitive retail markets, and restores incentives for efficient investment in generating capacity consistent with operating reliability criteria applied by system operators. It also responds to investment disincentives that have been associated with volatility in wholesale energy prices, limited hedging opportunities and to concerns about regulatory opportunism. 1

Natural games  

E-Print Network (OSTI)

Behavior in the context of game theory is described as a natural process that follows the 2nd law of thermodynamics. The rate of entropy increase as the payoff function is derived from statistical physics of open systems. The thermodynamic formalism relates everything in terms of energy and describes various ways to consume free energy. This allows us to associate game theoretical models of behavior to physical reality. Ultimately behavior is viewed as a physical process where flows of energy naturally select ways to consume free energy as soon as possible. This natural process is, according to the profound thermodynamic principle, equivalent to entropy increase in the least time. However, the physical portrayal of behavior does not imply determinism. On the contrary, evolutionary equation for open systems reveals that when there are three or more degrees of freedom for behavior, the course of a game is inherently unpredictable in detail because each move affects motives of moves in the future. Eventually, when no moves are found to consume more free energy, the extensive-form game has arrived at a solution concept that satisfies the minimax theorem. The equilibrium is Lyapunov-stable against variation in behavior within strategies but will be perturbed by a new strategy that will draw even more surrounding resources to the game. Entropy as the payoff function also clarifies motives of collaboration and subjective nature of decision making.

Magnetocumulative generator  

DOE Patents (OSTI)

An improved magnetocumulative generator is described that is useful for producing magnetic fields of very high energy content over large spatial volumes. The polar directed pleated magnetocumulative generator has a housing providing a housing chamber with an electrically conducting surface. The chamber forms a coaxial system having a small radius portion and a large radius portion. When a magnetic field is injected into the chamber, from an external source, most of the magnetic flux associated therewith positions itself in the small radius portion. The propagation of an explosive detonation through high-explosive layers disposed adjacent to the housing causes a phased closure of the chamber which sweeps most of the magnetic flux into the large radius portion of the coaxial system. The energy content of the magnetic field is greatly increased by flux stretching as well as by flux compression. The energy enhanced magnetic field is utilized within the housing chamber itself.

HEAT GENERATION  

DOE Patents (OSTI)

Heat is generated by the utilization of high energy neutrons produced as by nuclear reactions between hydrogen isotopes in a blanket zone containing lithium, a neutron moderator, and uranium and/or thorium effective to achieve multtplicatton of the high energy neutron. The rnultiplied and moderated neutrons produced react further with lithium-6 to produce tritium in the blanket. Thermal neutron fissionable materials are also produced and consumed in situ in the blanket zone. The heat produced by the aggregate of the various nuclear reactions is then withdrawn from the blanket zone to be used or otherwise disposed externally. (AEC)

9, 2011 at 2:00 P.M. 9, 2011 at 2:00 P.M. Next Release: Thursday, October 6, 2011 Overview Prices Storage Other Market Trends Overview (For the Week Ending Wednesday, September 28, 2011) Natural gas spot prices at most market locations across the country this past week initially declined and then began to creep upwards as natural gas use for power generation increased. The upward trend was halted yesterday, as prices at nearly all points retreated, possibly due to forecasts for considerably colder weather. After declining from $3.78 per million British thermal units (MMBtu) last Wednesday to $3.72 per MMbtu on Thursday, the Henry Hub spot price increased to $3.92 per MMBtu on Tuesday and closed at $3.88 per MMBtu yesterday.

Magnetocumulative generator  

DOE Patents (OSTI)

An improved magnetocumulative generator is described that is useful for producing magnetic fields of very high energy content over large spatial volumes. The polar directed pleated magnetocumulative generator has a housing (100, 101, 102, 103, 104, 105) providing a housing chamber (106) with an electrically conducting surface. The chamber (106) forms a coaxial system having a small radius portion and a large radius portion. When a magnetic field is injected into the chamber (106), from an external source, most of the magnetic flux associated therewith positions itself in the small radius portion. The propagation of an explosive detonation through high-explosive layers (107, 108) disposed adjacent to the housing causes a phased closure of the chamber (106) which sweeps most of the magnetic flux into the large radius portion of the coaxial system. The energy content of the magnetic field is greatly increased by flux stretching as well as by flux compression. The energy enhanced magnetic field is utilized within the housing chamber itself.

Natural networks  

E-Print Network (OSTI)

Scale-free and non-computable characteristics of natural networks are found to result from the least-time dispersal of energy. To consider a network as a thermodynamic system is motivated since ultimately everything that exists can be expressed in terms of energy. According to the variational principle, the network will grow and restructure when flows of energy diminish energy differences between nodes as well as relative to nodes in surrounding systems. The natural process will yield scale-free characteristics because the nodes that contribute to the least-time consumption of free energy preferably attach to each other. Network evolution is a path-dependent and non-deterministic process when there are two or more paths to consume a common source of energy. Although evolutionary courses of these non-Hamiltonian systems cannot be predicted, many mathematical functions, models and measures that characterize networks can be recognized as appropriate approximations of the thermodynamic equation of motion that has been derived from statistical physics of open systems.

Biogas Generator A Renewable Energy Project Kit The Pembina Institute What Is Biogas? Biogas is actually a mixture of gases, usually carbon dioxide and methane. It is produced by a few kinds of microorganisms, usually when air or oxygen is absent. (The absence of oxygen is called "anaerobic conditions.") Animals that eat a lot of plant material, particularly grazing animals such as cattle, produce large amounts of biogas. The biogas is produced not by the cow or elephant, but by billions of microor- ganisms living in its digestive system. Biogas also develops in bogs and at the bottom of lakes, where decaying organic matter builds up under wet and

Power generation method including membrane separation  

SciTech Connect

A method for generating electric power, such as at, or close to, natural gas fields. The method includes conditioning natural gas containing C.sub.3+ hydrocarbons and/or acid gas by means of a membrane separation step. This step creates a leaner, sweeter, drier gas, which is then used as combustion fuel to run a turbine, which is in turn used for power generation.

Dubuque generation station, Dubuque, Iowa  

SciTech Connect

Alliant Energy's Dubuque generation station is a fine example of why small does not mean insignificant in the power generation industry. This winner of the EUCG best performer award in the small plant category shows that its operating excellence towers over that of many larger and much newer coal-fired power plants. The plant has three operating units with boilers originally designed for Illinois basin coal but now Powder River Basin coal makes up 75% of the coal consumed. The boilers can also burn natural gas. 4 photos.

Economics of natural gas upgrading  

SciTech Connect

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.

Source codes as random number generators  

E-Print Network (OSTI)

Abstract—A random number generator generates fair coin flips by processing deterministically an arbitrary source of nonideal randomness. An optimal random number generator generates asymptotically fair coin flips from a stationary ergodic source at a rate of bits per source symbol equal to the entropy rate of the source. Since optimal noiseless data compression codes produce incompressible outputs, it is natural to investigate their capabilities as optimal random number generators. In this paper we show under general conditions that optimal variable-length source codes asymptotically achieve optimal variable-length random bit generation in a rather strong sense. In particular, we show in what sense the Lempel–Ziv algorithm can be considered an optimal universal random bit generator from arbitrary stationary ergodic random sources with unknown distributions. Index Terms — Data compression, entropy, Lempel–Ziv algorithm, random number generation, universal source coding.

North American Natural Gas Markets  

Science Conference Proceedings (OSTI)

This report summarizes die research by an Energy Modeling Forum working group on the evolution of the North American natural gas markets between now and 2010. The group's findings are based partly on the results of a set of economic models of the natural gas industry that were run for four scenarios representing significantly different conditions: two oil price scenarios (upper and lower), a smaller total US resource base (low US resource case), and increased potential gas demand for electric generation (high US demand case). Several issues, such as the direction of regulatory policy and the size of the gas resource base, were analyzed separately without the use of models.

Natural gas and electricity optimal power flow  

E-Print Network (OSTI)

Abstract — In this paper, the combined natural gas and electric optimal power flow (GEOPF) is presented. It shows fundamental modeling of the natural gas network to be used for the GEOPF, and describes the equality constraints which describe the energy transformation between gas and electric networks at combined nodes (i.e., generators). We also present the formulation of the natural gas loadflow problem, which includes the amount of gas consumed in compressor stations. Case studies are presented to show the sensitivity of the real power generation to wellhead gas prices. Results from the simulation demonstrate that the GEOPF can provide social welfare maximizing solutions considering both gas and electric networks. I.

Combined cycle meets Thailand's growing power demands  

SciTech Connect

This article describes how an ample supply of natural gas led the Electricity Generating Authority of Thailand (EGAT) to choose gas-fired combustion turbines. Thailand's rapid industrialization, which began in the late 1980's, placed a great strain on the country's electricity supply system. The demand for electricity grew at an astonishing 14% annually. To deal with diminishing reserve capacity margins, the EGAT announced, in 1988, a power development program emphasizing gas-fired combined cycle power plants. Plans included six 320-MW combined cycle blocks at three sites, and an additional 600-MW gas- and oil-fired thermal plant at Bang Pakong. As electricity demand continued to increase, EGAT expanded its plans to include two additional 320-MW combined cycle blocks, a 600-MW combined cycle block, and a 650-MW gas- and oil-fired thermal plant. All are currently in various stages of design and construction.

Natural Gas Weekly Update  

Gasoline and Diesel Fuel Update (EIA)

2, 2003 (next release 2:00 p.m. on June 19) 2, 2003 (next release 2:00 p.m. on June 19) Moderate temperatures across the country except in the Southwest contributed to natural gas spot prices easing 25 to 50 cents per MMBtu since Wednesday, June 4. On the week (Wednesday, June 4-Wednesday, June 11), the Henry Hub spot price dropped 35 cents per MMBtu to $6.06. The NYMEX futures contract for July delivery at the Henry Hub fell about 16 cents per MMBtu to $6.213. Natural gas in storage as of Friday, June 6, increased to 1,324 Bcf, which is 25.2 percent below the 5-year average. The spot price for West Texas Intermediate (WTI) crude oil rose $2.36 per barrel on the week to yesterday's (June 11) closing price of $32.17 per barrel, or $5.55 per MMBtu. Prices: Natural gas spot prices at many market locations in the Lower 48 States have declined for three consecutive trading days from Friday peaks as key market areas in the Midwest and the Eastern seaboard have experienced unseasonably cool weather. Although prices remain elevated, the slackened demand for natural gas for electric generation has contributed to prices generally softening across the board. For the week, the spot price at the Henry Hub dropped about 6 percent to $6.06 per MMBtu, while other pricing points on the Gulf Coast showed slightly greater declines and fell below the $6-mark. The overall easing of prices may reflect also the slightly improving storage picture as injections in 7 of the past 8 weeks have exceeded the 5-year average with a record net addition reported last Thursday. Although the storage refill season started slowly, injections have increased considerably, with at least one major interstate pipeline serving the Northeast, Tennessee Gas Pipeline, announcing restrictions to shippers due to injection nominations exceeding capacity. The spot price at Tennessee Gas Pipeline's Zone 6, which serves major citygates in New York and other Northeastern states, this week fell 47 cents per MMBtu to $6.30. In contrast to the East, prices in the West moved higher early in the week, as maintenance on El Paso Natural Gas in the San Juan Basin restricted deliveries from the region and a heat wave sparked buying at pricing locations in California and New Mexico. The spot price at the Southern California border surged 61 cents per MMBtu on Monday to $5.78, but has since dropped to $5.51, which is a net decline of 51 cents since Wednesday, June 4.

Linking electroweak and gravitational generators  

E-Print Network (OSTI)

Using complexified quaternions, an intriguing link between generators of two different and surprisingly commuting four-dimensional representations of the SU(2)xU(1) Lie group, and generators of two four-dimensional spin 1/2 representations of the Spin(3,1) Lie group is established: the former generators completely determine the latter ones, and cross-combined they constitute two different, but closely related, four-dimensional representations of Spin(3,1)xSU(2)xU(1). These representations are used to construct a Spin(3,1)xSU(2)xU(1) gauge invariant Lagrangian, containing two four-spinors consisting not as usual of Weyl two-spinors of opposite helicity and equal weak isospin, but instead of Weyl two-spinors of opposite weak isospin and equal helicity, a construction which arises naturally from the mathematical formalism itself. A possible future generalization, using complexified octonions, is discussed.
