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.

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.

SciTech Connect

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.

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. We consider the medium-term risk management problem of a UK gas-fired power plant that faces stochastic electricity and gas prices.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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 150-180F (65-82C), 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.

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.

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

SciTech Connect

This report provides results from the first 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 operations. Detailed emission rate and chemical speciation test results for a refinery gas-fired process heater and plans for cogeneration gas turbine tests and pilot-scale tests are presented. Tests were performed using a research dilution sampling apparatus and traditional EPA methods to compare PM2.5 mass and chemical speciation. Test plans are presented for a gas turbine facility that will be tested in the fourth quarter of 2002. A preliminary approach for pilot-scale tests is presented that will help define design constraints for a new dilution sampler design that is smaller, lighter, and less costly to use.

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.

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.

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.

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.

Since last years GTC Conference, a considerable number of significant events have occurred in the gasification technology marketplace. New IGCC projects have come on stream with commercial operation, other new IGCC projects have been announced and started in development, environmental issues have gained emphasis, and energy prices, notably natural gas, have escalated dramatically. Directionally, all of these events appear to have created a more favorable atmosphere for IGCC projects. Related to an ongoing IGCC project currently in development, a joint analysis has been performed by Global Energy, General Electric Power Systems, and Praxair to evaluate technical and economic elements for the performance of BGL Gasification Technology based on solid hydrocarbon fuel feed to an IGCC for power generation. Results of the analysis provide a picture of the relative economics in todays environment for electrical power generation by conventional natural gas fired combined cycle power systems compared to using BGL Gasification Technology in an IGCC configuration. 2

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.

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.

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.

Power plants with topping gas turbines and coal gasification planning of new plants and upgrading of existing plants  

Science Conference Proceedings (OSTI)

This paper reports on existing and new power plants improved environmentally and economically by integrating gas turbines in the plant process. The rate of additional firing has an influence on the overall plant efficiency. The influence of the additional firing of natural gas-fired power plants is compared to that of power plants with integrated coal gasification. The differences are explained. The result of the examination lead to recommendations for the design of new plants and for upgrading of existing plants. The advantages of topping gas turbines are shown by examples of new power plants and upgraded plants.

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.

Advanced design nuclear power plants: Competitive, economical electricity. An analysis of the cost of electricity from coal, gas and nuclear power plants  

SciTech Connect

This report presents an updated analysis of the projected cost of electricity from new baseload power plants beginning operation around the year 2000. Included in the study are: (1) advanced-design, standardized nuclear power plants; (2) low emissions coal-fired power plants; (3) gasified coal-fired power plants; and (4) natural gas-fired power plants. This analysis shows that electricity from advanced-design, standardized nuclear power plants will be economically competitive with all other baseload electric generating system alternatives. This does not mean that any one source of electric power is always preferable to another. Rather, what this analysis indicates is that, as utilities and others begin planning for future baseload power plants, advanced-design nuclear plants should be considered an economically viable option to be included in their detailed studies of alternatives. Even with aggressive and successful conservation, efficiency and demand-side management programs, some new baseload electric supply will be needed during the 1990s and into the future. The baseload generating plants required in the 1990s are currently being designed and constructed. For those required shortly after 2000, the planning and alternatives assessment process must start now. It takes up to ten years to plan, design, license and construct a new coal-fired or nuclear fueled baseload electric generating plant and about six years for a natural gas-fired plant. This study indicates that for 600-megawatt blocks of capacity, advanced-design nuclear plants could supply electricity at an average of 4.5 cents per kilowatt-hour versus 4.8 cents per kilowatt-hour for an advanced pulverized-coal plant, 5.0 cents per kilowatt-hour for a gasified-coal combined cycle plant, and 4.3 cents per kilowatt-hour for a gas-fired combined cycle combustion turbine plant.

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.

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.

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.

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.

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.

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.

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.

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

Valuing Gas Power Plants with CO2 Capture and Tradable Quotas  

E-Print Network (OSTI)

We analyze investment in a gas fired power plant in a regime with tradable quotas for CO 2 emissions and with an option to install CO 2 capture technology. Such equipment is very costly and we find that high subsidies are required to entice the investors to install it, even when the captured CO 2 can be sold for enhanced oil recovery. Investment valuation is based on market prices of long term prices of energy forward contracts. The plant's operating flexibility and the investment delay opportunity under gas and electricity price uncertainty is taken into account. Based on prices from the Scandinavian electricity market and the UK natural gas market we find that the power plant investment should be delayed.

Price risk management: Electric power vs. natural gas  

Science Conference Proceedings (OSTI)

As deregulation continues, will electricity resemble gas as a commodity, when it comes to futures markets and forward deals? Overall, yes; the signs are there. But differences will remain-in volatility, the prominence of regional factors, and the importance of shortrun engineering fundamentals. This article examines these differences and concludes that engineering and economic analyses will prove more important in the future in assessing risk in the electric power commodity market than in the gas industry.

FUEL CONSUMPTION AND COST SAVINGS OF CLASS 8 HEAVY-DUTY TRUCKS POWERED BY NATURAL GAS  

Science Conference Proceedings (OSTI)

We compare the fuel consumption and greenhouse gas emissions of natural gas and diesel heavy-duty (HD) class 8 trucks under consistent simulated drive cycle conditions. Our study included both conventional and hybrid HD trucks operating with either natural gas or diesel engines, and we compare the resulting simulated fuel efficiencies, fuel costs, and payback periods. While trucks powered by natural gas engines have lower fuel economy, their CO2 emissions and costs are lower than comparable diesel trucks. Both diesel and natural gas powered hybrid trucks have significantly improved fuel economy, reasonable cost savings and payback time, and lower CO2 emissions under city driving conditions. However, under freeway-dominant driving conditions, the overall benefits of hybridization are considerably less. Based on payback period alone, non-hybrid natural gas trucks appear to be the most economic option for both urban and freeway driving environments.

Issues in Energy Economics Led by Emerging Linkages between the Natural Gas and Power Sectors  

Science Conference Proceedings (OSTI)

Fuel prices in 2006 continued at record levels, with uranium continuing upward unabated and coal, SO{sub 2} emission allowances, and natural gas all softening. This softening did not continue for natural gas, however, whose prices rose, fell and rose again, first following weather influences and, by the second quarter of 2007, continuing at high levels without any support from fundamentals. This article reviews these trends and describes the remarkable increases in fuel expenses for power generation. By the end of 2005, natural gas claimed 55% of annual power sector fuel expenses, even though it was used for only 19% of electric generation. Although natural gas is enormously important to the power sector, the sector also is an important driver of the natural gas market-growing to over 28% of the market even as total use has declined. The article proceeds to discuss globalization, natural gas price risk, and technology developments. Forces of globalization are poised to affect the energy markets in new ways-new in not being only about oil. Of particular interest in the growth of intermodal traffic and its a little-understood impacts on rail traffic patterns and transportation costs, and expected rapidly expanding LNG imports toward the end of the decade. Two aspects of natural gas price risk are discussed: how understanding the use of gas in the power sector helps define price ceilings and floors for natural gas, and how the recent increase in the natural gas production after years of record drilling could alter the supply-demand balance for the better. The article cautions, however, that escalation in natural gas finding and development costs is countering the more positive developments that emerged during 2006. Regarding technology, the exploitation of unconventional natural gas was one highlight. So too was the queuing up of coal-fired power plants for the post-2010 period, a phenomenon that has come under great pressure with many consequences including increased pressures in the natural gas market. The most significant illustration of these forces was the early 2007 suspension of development plans by a large power company, well before the Supreme Court's ruling on CO{sub 2} as a tailpipe pollutant and President Bush's call for global goals on CO{sub 2} emissions.

Resource Contingency Program - Oregon : Final Environmental Impact Statement, Hermiston Power Project.  

SciTech Connect

The Bonneville Power Administration (BPA) has statutory responsibilities to supply electrical power to its utility, industrial, and other customers in the Pacific Northwest. In 1990, to cover the outer range of potential load growth with new resources, BPA embarked upon the Resource Contingency Program (RCP). Instead of buying or building generating plants now, BPA has purchased options to acquire power later, if and when it is needed. The decision to acquire any of these option energy projects to fulfill statutory supply obligations will be influenced by Federal system load growth, the outcome of BPA`s Business Plan, required operational changes in Columbia-Snake River Hydroelectric facilities, and the loss of major generating resources. In September 1993, three option development agreements were signed with three proposed natural gas-fired, combined cycle combustion turbine CT projects near Chehalis and Satsop, Washington, and near Hermiston, Oregon. Together these three projects could supply BPA with 1,090 average megawatts (aMW) of power. Under these agreements, sponsors are obtaining permits and conducting project design work, and BPA is completing this EIS process. In September 1993, BPA published a Notice of Intent to prepare an environmental impact statement (EIS) on these three proposed gas-fired combustion turbine projects and held public scoping meetings in October 1993 at each site. In February 1994, BPA released an Implementation Plan on the proposed scope of the EIS. A draft EIS on the three proposed projects was published in February 1995. The impacts of the Chehalis and Satsop projects located in Washington State will be covered in one EIS document, while the impacts of the Hermiston project located in Oregon are covered in this final EIS document. It is BPA`s intent to continue to base the analysis of impacts on the assumption that all three projects may be constructed at some point in the future.

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.

Hydrogen Resource Assessment: Hydrogen Potential from Coal, Natural Gas, Nuclear, and Hydro Power  

DOE Green Energy (OSTI)

This paper estimates the quantity of hydrogen that could be produced from coal, natural gas, nuclear, and hydro power by county in the United States. The study estimates that more than 72 million tonnes of hydrogen can be produced from coal, natural gas, nuclear, and hydro power per year in the country (considering only 30% of their total annual production). The United States consumed about 396 million tonnes of gasoline in 2007; therefore, the report suggests the amount of hydrogen from these sources could displace about 80% of this consumption.

Hybrid power towers: A solar boost for natural gas in the Southwest  

SciTech Connect

A new concept to combine central receiver technology with highly efficient natural gas turbines has sparked interest among key utilities in the southwestern United States. The result is a fully dispatchable hybrid power tower that`s expected to use 30% less natural gas than its conventional counterpart. Developed by researcher at the US DOE`s National Renewable Energy Laboratory (NREL), the hybrid power tower is the focus of a developing partnership with the Sacramento Municipal Utility District (SMUD) in California. Although some solar advocates criticize the use of nonrenewable natural gas, the hybrid concept mitigates many of the current barriers to commercializing solar thermal technology. NREL`s innovative concept uses a small central receiver plant to preheat combustion air for natural gas turbines. Solar thermal energy displaces the use of nonrenewable fossil fuel throughout much of the day. When solar heat is no longer available, the natural gas turbines ensure continuous operation to meet a utility`s need for baseload, intermediate, or peaking power, as desired. The combined-cycle power tower has many attractive features, but the bottom line is it can be commercialized in today`s utility market.

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.

Quantifying the value that wind power provides as a hedge against volatile natural gas prices  

DOE Green Energy (OSTI)

Advocates of renewable energy have long argued that wind power and other renewable technologies can mitigate fuel price risk within a resource portfolio. Such arguments--made with renewed vigor in the wake of unprecedented natural gas price volatility during the winter of 2000/2001--have mostly been qualitative in nature, however, with few attempts to actually quantify the price stability benefit that wind and other renewables provide. This paper attempts to quantify this benefit by equating it with the cost of achieving price stability through other means, particularly gas-based financial derivatives (futures and swaps). We find that over the past two years, natural gas consumers have had to pay a premium of roughly 0.50 cents/kWh over expected spot prices to lock in natural gas prices for the next 10 years. This incremental cost is potentially large enough to tip the scales away from new investments in natural gasfired generation and in favor of investments in wind power and other renewable technologies.

Science Conference Proceedings (OSTI)

In recent years it has been recognized that the application of passive safety systems (i.e., those whose operation takes advantage of natural forces such as convection and gravity), can contribute to simplification and potentially to improved economics of new nuclear power plant designs. In 1991 the IAEA Conference on ''The Safety of Nuclear Power: Strategy for the Future'' noted that for new plants the use of passive safety features is a desirable method of achieving simplification and increasing the reliability of the performance of essential safety functions, and should be used wherever appropriate''.

Science Conference Proceedings (OSTI)

The Natural Bridges National Monument in southeastern Utah is the location of the world's largest solar photovoltaic power system. This system, which operates in a stand-alone mode without utility backup, supplies from 300 to 400 kWh/day of 60-Hz AC electrical energy to the diversified loads in the monument headquarters area. A diesel-powered generator serves as backup for the system. The solutions to a number of problems encountered in the design, fabrication, testing and early operation of the system are discussed.

Surface treated natural graphite as anode material for high-power Li-ion battery applications.  

Science Conference Proceedings (OSTI)

High power application of Li-ion battery in hybrid electrical vehicles requires low cost and safe cell materials. Among the various carbon anode materials used in lithium ion batteries, natural graphite shows the most promise with advantages in performance and cost. However, natural graphite is not compatible with propylene carbonate (PC)-based electrolytes, which have a lower melting point and improved safety characteristics. The problem with it is that the molecules of propylene carbonate intercalate with Li+ into graphite, and that frequently leads to the exfoliation of the graphite matrix.

The effect of prechambers on flame propagation in a natural-gas powered engine  

DOE Green Energy (OSTI)

Large-bore two-stroke natural-gas-fueled engines commonly are located along natural gas pipelines, siphoning off a small portion of gas from the pipeline for use as a fuel, in order to pump the remaining gas along the pipeline. The KIVA-3 computational fluid dynamics program was used to simulate the compression stroke, combustion, and power stroke in a natural-gas-fueled engine by solving the full Navier-Stokes equations. These calculations include cases with and without prechambers. Prechamber stoichiometry and spark locations were independently varied with the goal of understanding how various prechamber parameters influence the ignition of the fuel-air charge in the main chamber. The goal is to allow the use of very lean main-chamber charges to minimize nitrogen oxide (NO{sub x}) production. These calculations were performed in both two and three dimensions.

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.

In this system, sodium evaporates from a surface that is heated by a stream of hot gases and the liquid metal then condenses on the heater tubes of a Stirling engine where energy is transferred to the engine`s helium working fluid. Recent tests on a prototype unit illustrated that a compact (8 cm {times} 13 cm {times} 16 cm) sodium evaporator can routinely transfer 15-kW{sub t} of energy at an operating vapor temperature of 760{degrees}C. Four of these prototype units will eventually be used to power a 25-kW{sub e} Stirling engine system. Design details and test results from the prototype unit are presented in this paper.

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.

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.

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.

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.

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.

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.

Concentrating Solar Power: Technology Overview  

Science Conference Proceedings (OSTI)

Concentrating Solar Power (CSP) has the potential to contribute significantly to the generation of electricity by renewable energy resources in the U.S.. Thermal storage can extend the duty cycle of CSP beyond daytime hours to early evening where the value of electricity is often the highest. The potential solar resource for the southwest U.S. is identified, along with the need to add power lines to bring the power to consumers. CSP plants in the U.S. and abroad are described. The CSP cost of electricity at the busbar is discussed. With current incentives, CSP is approaching competiveness with conventional gas-fired systems during peak-demand hours when the price of electricity is the highest. It is projected that a mature CSP industry of over 4 GWe will be able to reduce the energy cost by about 50%, and that U.S. capacity could be 120 GW by 2050.

Adaptation of a commercially available 200 kW natural gas fuel cell power plant for operation on a hydrogen rich gas stream  

DOE Green Energy (OSTI)

International Fuel Cells (IFC) has designed a hydrogen fueled fuel cell power plant based on a modification of its standard natural gas fueled PC25{trademark} C fuel cell power plant. The natural gas fueled PC25 C is a 200 kW, fuel cell power plant that is commercially available. The program to accomplish the fuel change involved deleting the natural gas processing elements, designing a new fuel pretreatment subsystem, modifying the water and thermal management subsystem, developing a hydrogen burner to combust unconsumed hydrogen, and modifying the control system. Additionally, the required modifications to the manufacturing and assembly procedures necessary to allow the hydrogen fueled power plant to be manufactured in conjunction with the on-going production of the standard PC25 C power plants were identified. This work establishes the design and manufacturing plan for the 200 kW hydrogen fueled PC25 power plant.

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.

Report on audit of Bonneville Power Administration`s energy resource programs  

SciTech Connect

The Bonneville Power Administration (Bonneville) must ensure that the costs of its contracts for energy resources are as low as reasonably possible and that the resources are needed. During the audit, we reviewed Bonneville`s energy resource programs and focused on its purchase of electrical output from natural gas fired combustion turbines. The objective of this audit was to determine if Bonneville paid excessive costs to acquire the electrical output from combustion turbine facilities. The audit showed that Bonneville contracted to purchase the output from a combustion turbine facility at excessive cost, and that the electricity was not needed. The cost of the electricity under this contract exceeded the amount of revenue Bonneville could obtain by selling it. Bonneville estimated it would operate the generation facility for only 6 months of the year; the contract, however, required Bonneville to pay the fixed costs of the facility during the other 6 months. Consequently, the cost of the electricity plus the fixed costs in the first year of the contract would exceed revenues by $20.9 million. The contract also contained cost escalators that exceeded the rate of inflation. These cost escalators combined with the excessive initial cost resulted in projected excessive costs of $146.8 million in the first 5 years of the contract, Finally, the contract was not needed due to competition from similar facilities and a desire by customers to diversify their sources of electricity.

Performance and economic evaluation of the seahorse natural gas hot water heater conversion at Fort Stewart. Final report  

SciTech Connect

The Federal government is the largest single energy consumer in the United States with consumption of nearly 1.5 quads/year of energy (10{sup 15} quad = 1015 Btu) and cost valued at nearly $10 billion annually. The US Department of Energy`s (DOE) Federal Energy Management Program (FEMP) supports efforts to reduce energy use and associated expenses in the Federal sector. One such effort, the New Technology Demonstration Program (NTDP) seeks to evaluate new energy -- saving US technologies and secure their more timely adoption by the US government. Pacific Northwest Laboratory (PNL) is one of four DOE laboratories that participate in the New Technologies Demonstration Program, providing technical expertise and equipment to evaluate new, energy-saving technologies being studied under that program. This report provides the results of a field evaluation that PNL conducted for DOE/FEMP with funding support from the US Department of Defense (DoD) Strategic Environmental Research and Development Program (SERDP) to examine the performance of 4 candidate energy-saving technology-a water heater conversion system to convert electrically powered water heaters to natural gas fuel. The unit was installed at a single residence at Fort Stewart, a US Army base in Georgia, and the performance was monitored under the NTDP. Participating in this effort under a Cooperative Research and Development Agreement (CRADA) were Gas Fired Products, developers of the technology; the Public Service Company of North Carolina; Atlanta Gas Light Company; the Army Corps of Engineers; Fort Stewart; and Pacific Northwest Laboratory.

The current natural gas market is depressed by a combination of unusual factorsa great excess of supply and weak demand. Excess supply comes from the momentum of exploration and production (EP) to the new U.S. gas shale plays, a phenomenon barely 18 months old and a game-changing event in the industry. Weak demand comes from the "Great Recession." The seeds for correcting this imbalance would appear to be a dramatic cutback in drilling, which has collapsed over the past year and which is a principal focu...

NREL researchers are finding ways to mimic photosynthesis by combining enzymes with nanoparticles - particles on the scale of a billionth of a meter - to produce hydrogen directly from water and sunlight. This breakthrough project began in 2008 with scientists and researchers asking how they might learn from nature and develop a synthetic process that is more efficient than plants at converting sunlight to hydrogen. The goal was to find a new way to produce hydrogen that could then be commercialized inexpensively for fuel cells and other uses. Among the various approaches to making hydrogen, the NREL researchers wondered about a hybrid molecular assembly that might pair the best natural molecule with a synthesized nanoparticle. Researchers looked at using hydrogenase enzymes as one part of the equation. These biological catalysts can convert electrons and protons into hydrogen gas, or convert hydrogen into electrons and protons. The choice seemed worthwhile because the hydrogenase enzyme has some intriguing properties: a high substrate selectivity, meaning a very high preference for catalyzing reactions with protons rather than with other atoms and molecules; and fast turnover, which enables it to produce a hydrogen molecule in milliseconds.

Development of a dynamic simulator for a natural gas combined cycle (NGCC) power plant with post-combustion carbon capture  

Science Conference Proceedings (OSTI)

The AVESTAR Center located at the U.S. Department of Energys National Energy Technology Laboratory and West Virginia University is a world-class research and training environment dedicated to using dynamic process simulation as a tool for advancing the safe, efficient and reliable operation of clean energy plants with CO{sub 2} capture. The AVESTAR Center was launched with a high-fidelity dynamic simulator for an Integrated Gasification Combined Cycle (IGCC) power plant with pre-combustion carbon capture. The IGCC dynamic simulator offers full-scope Operator Training Simulator (OTS) Human Machine Interface (HMI) graphics for realistic, real-time control room operation and is integrated with a 3D virtual Immersive Training Simulator (ITS), thus allowing joint control room and field operator training. The IGCC OTS/ITS solution combines a gasification with CO{sub 2} capture process simulator with a combined cycle power simulator into a single high-performance dynamic simulation framework. This presentation will describe progress on the development of a natural gas combined cycle (NGCC) dynamic simulator based on the syngas-fired combined cycle portion of AVESTARs IGCC dynamic simulator. The 574 MW gross NGCC power plant design consisting of two advanced F-class gas turbines, two heat recovery steam generators (HRSGs), and a steam turbine in a multi-shaft 2x2x1 configuration will be reviewed. Plans for integrating a post-combustion carbon capture system will also be discussed.

Expanding the potential for saline formations : modeling carbon dioxide storage, water extraction and treatment for power plant cooling.  

Science Conference Proceedings (OSTI)

The National Water, Energy and Carbon Sequestration simulation model (WECSsim) is being developed to address the question, 'Where in the current and future U.S. fossil fuel based electricity generation fleet are there opportunities to couple CO{sub 2} storage and extracted water use, and what are the economic and water demand-related impacts of these systems compared to traditional power systems?' The WECSsim collaborative team initially applied this framework to a test case region in the San Juan Basin, New Mexico. Recently, the model has been expanded to incorporate the lower 48 states of the U.S. Significant effort has been spent characterizing locations throughout the U.S. where CO{sub 2} might be stored in saline formations including substantial data collection and analysis efforts to supplement the incomplete brine data offered in the NatCarb database. WECSsim calculates costs associated with CO{sub 2} capture and storage (CCS) for the power plant to saline formation combinations including parasitic energy costs of CO{sub 2} capture, CO{sub 2} pipelines, water treatment options, and the net benefit of water treatment for power plant cooling. Currently, the model can identify the least-cost deep saline formation CO{sub 2} storage option for any current or proposed coal or natural gas-fired power plant in the lower 48 states. Initial results suggest that additional, cumulative water withdrawals resulting from national scale CCS may range from 676 million gallons per day (MGD) to 30,155 MGD depending on the makeup power and cooling technologies being utilized. These demands represent 0.20% to 8.7% of the U.S. total fresh water withdrawals in the year 2000, respectively. These regional and ultimately nation-wide, bottom-up scenarios coupling power plants and saline formations throughout the U.S. can be used to support state or national energy development plans and strategies.

THE SLOW-MODE NATURE OF COMPRESSIBLE WAVE POWER IN SOLAR WIND TURBULENCE  

Science Conference Proceedings (OSTI)

We use a large, statistical set of measurements from the Wind spacecraft at 1 AU, and supporting synthetic spacecraft data based on kinetic plasma theory, to show that the compressible component of inertial range solar wind turbulence is primarily in the kinetic slow mode. The zero-lag cross-correlation C({delta}n, {delta}B{sub ||}) between proton density fluctuations {delta}n and the field-aligned (compressible) component of the magnetic field {delta}B{sub ||} is negative and close to -1. The typical dependence of C({delta}n, {delta}B{sub ||}) on the ion plasma beta {beta}{sub i} is consistent with a spectrum of compressible wave energy that is almost entirely in the kinetic slow mode. This has important implications for both the nature of the density fluctuation spectrum and for the cascade of kinetic turbulence to short wavelengths, favoring evolution to the kinetic Alfven wave mode rather than the (fast) whistler mode.

System Design of a Natural Gas PEM Fuel Cell Power Plant for Buildings  

DOE Green Energy (OSTI)

The following conclusions are made based on this analysis effort: (1) High-temperature PEM data are not available; (2) Stack development effort for Phase II is required; (3) System results are by definition preliminary, mostly due to the immaturity of the high-temperature stack; other components of the system are relatively well defined; (4) The Grotthuss conduction mechanism yields the preferred system characteristics; the Grotthuss conduction mechanism is also much less technically mature than the vehicle mechanism; (5) Fuel processor technology is available today and can be procured for Phase II (steam or ATR); (6) The immaturity of high-temperature membrane technology requires that a robust system design be developed in Phase II that is capable of operating over a wide temperature and pressure range - (a) Unpressurized or Pressurized PEM (Grotthuss mechanism) at 140 C, Highest temperature most favorable, Lowest water requirement most favorable, Pressurized recommended for base loaded operation, Unpressurized may be preferred for load following; (b) Pressurized PEM (vehicle mechanism) at about 100 C, Pressure required for saturation, Fuel cell technology currently available, stack development required. The system analysis and screening evaluation resulted in the identification of the following components for the most promising system: (1) Steam reforming fuel processor; (2) Grotthuss mechanism fuel cell stack operating at 140 C; (3) Means to deliver system waste heat to a cogeneration unit; (4) Pressurized system utilizing a turbocompressor for a base-load power application. If duty cycling is anticipated, the benefits of compression may be offset due to complexity of control. In this case (and even in the base loaded case), the turbocompressor can be replaced with a blower for low-pressure operation.

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.

Final Report: Assessment of Combined Heat and Power Premium Power Applications in California  

Science Conference Proceedings (OSTI)

This report analyzes the current economic and environmental performance of combined heat and power (CHP) systems in power interruption intolerant commercial facilities. Through a series of three case studies, key trade-offs are analyzed with regard to the provision of black-out ridethrough capability with the CHP systems and the resutling ability to avoid the need for at least some diesel backup generator capacity located at the case study sites. Each of the selected sites currently have a CHP or combined heating, cooling, and power (CCHP) system in addition to diesel backup generators. In all cases the CHP/CCHP system have a small fraction of the electrical capacity of the diesel generators. Although none of the selected sites currently have the ability to run the CHP systems as emergency backup power, all could be retrofitted to provide this blackout ride-through capability, and new CHP systems can be installed with this capability. The following three sites/systems were used for this analysis: (1) Sierra Nevada Brewery - Using 1MW of installed Molten Carbonate Fuel Cells operating on a combination of digestor gas (from the beer brewing process) and natural gas, this facility can produce electricty and heat for the brewery and attached bottling plant. The major thermal load on-site is to keep the brewing tanks at appropriate temperatures. (2) NetApp Data Center - Using 1.125 MW of Hess Microgen natural gas fired reciprocating engine-generators, with exhaust gas and jacket water heat recovery attached to over 300 tons of of adsorption chillers, this combined cooling and power system provides electricity and cooling to a data center with a 1,200 kW peak electrical load. (3) Kaiser Permanente Hayward Hospital - With 180kW of Tecogen natural gas fired reciprocating engine-generators this CHP system generates steam for space heating, and hot water for a city hospital. For all sites, similar assumptions are made about the economic and technological constraints of the power generation system. Using the Distributed Energy Resource Customer Adoption Model (DER-CAM) developed at the Lawrence Berkeley National Laboratory, we model three representative scenarios and find the optimal operation scheduling, yearly energy cost, and energy technology investments for each scenario below: Scenario 1 - Diesel generators and CHP/CCHP equipment as installed in the current facility. Scenario 1 represents a baseline forced investment in currently installed energy equipment. Scenario 2 - Existing CHP equipment installed with blackout ride-through capability to replace approximately the same capacity of diesel generators. In Scenario 2 the cost of the replaced diesel units is saved, however additional capital cost for the controls and switchgear for blackout ride-through capability is necessary. Scenario 3 - Fully optimized site analysis, allowing DER-CAM to specify the number of diesel and CHP/CCHP units (with blackout ride-through capability) that should be installed ignoring any constraints on backup generation. Scenario 3 allows DER-CAM to optimize scheduling and number of generation units from the currently available technologies at a particular site. The results of this analysis, using real data to model the optimal schedulding of hypothetical and actual CHP systems for a brewery, data center, and hospital, lead to some interesting conclusions. First, facilities with high heating loads will typically prove to be the most appropriate for CHP installation from a purely economic standpoint. Second, absorption/adsorption cooling systems may only be economically feasible if the technology for these chillers can increase above current best system efficiency. At a coefficient of performance (COP) of 0.8, for instance, an adsorption chiller paired with a natural gas generator with waste heat recovery at a facility with large cooling loads, like a data center, will cost no less on a yearly basis than purchasing electricity and natural gas directly from a utility. Third, at marginal additional cost, if the reliability of CHP systems proves to be at

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.

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.

Wallula Power Project and Wallula - McNary Transmission Line Project Final Environmental Impact Statement  

Science Conference Proceedings (OSTI)

Wallula Generation, LLC proposes to construct a 1,300-megawatt (MW) natural gas-fired combined-cycle combustion gas turbine facility (the Wallula Power Project). The project would be located in the northwestern portion of Walla Walla County, Washington, approximately 8 miles south of the City of Pasco, 2 miles north of the unincorporated community of Wallula, and 7 miles southeast of the unincorporated community of Burbank. The purpose of the proposed power project is to provide energy to meet the needs of the Northwest and other interconnected electric transmission areas where electrical energy is needed. Firm transmission of the power generated by the Wallula Power Project would require construction of a new 500-kilovolt (kV) transmission line and construction of a new switchyard near Smiths Harbor. Approximately 5.1 miles of new transmission line from the proposed generation plant to the new switchyard would be completed. An additional 28 miles of new transmission line from the Smiths Harbor Switchyard to the McNary Substation would be constructed adjacent to the existing Lower Monumental-McNary transmission line and upgrades completed to the existing McNary Substation if loads are exceeded on the existing line. Wallula Generation, LLC, would construct and operate the generation plant and associated facilities, including the makeup water supply line. Bonneville would design, construct, and operate the two 500 kV transmission line segments and switchyard. To supply natural gas to the plant site, a 5.9-mile pipeline interconnection would be engineered, constructed, owned, and operated by PG&E Gas Transmission-Northwest (GTN). This EIS evaluates the environmental impacts of the proposed action, which includes the proposed power plant and 33-mile transmission line. It also evaluates an alternative using taller towers and longer spans between towers along part of the transmission line, and the use of an alternative approach for the transmission line where it would enter the McNary Substation. The No Action Alternative is also addressed.

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.

· The increase in natural gas consumption in the electric power sector over the past few years has resulted from building new gas-fired electric genera- tors across the country. In 2001 alone, more than 40,000 megawatts of efficient, gas-fired electric power generation was placed into service. Gas-fired turbines have become the favored new source of elec- tricity for their capability to start up quickly during peak demand periods. · Total natural gas consumed in the electric power sector is now roughly 26 percent of total deliveries to consumers in the country, compared to approxi- mately 20 percent in 1997. In terms of volumes con- sumed by sector, natural gas consumption for electric power generation is second only to industrial consumption. · End use consumer prices increased in each sector of the natural gas market in 2001 (Figure 5). Prices climbed 24 percent in the residential

Health effects and related standards for fossil-fuel and geothermal power plants. Volume 6 of health and safety impacts of nuclear, geothermal, and fossil-fuel electric generation in California. [In California  

DOE Green Energy (OSTI)

This report reviews health effects and related standards for fossil-fuel and geothermal power plants, emphasizing impacts which may occur through emissions into the atmosphere, and treating other impacts briefly. Federal regulations as well as California state and local regulations are reviewed. Emissions are characterized by power plant type, including: coal-fired, oil-fired, gas-fired, combined cycle and advanced fossil-fuel plants; and liquid and vapor geothermal systems. Dispersion and transformation of emissions are treated. The state of knowledge of health effects, based on epidemiological, physiological, and biomedical studies, is reviewed.

Drifting localization of ionization runaway: Unraveling the nature of anomalous transport in high power impulse magnetron sputtering  

Science Conference Proceedings (OSTI)

The plasma over the magnetrons erosion racetrack is not azimuthally uniform but concentrated in distinct dense plasma zones which move in the {vector E}{vector B} direction with about 10% of the electrons {vector E}{vector B}/B{sup 2} drift velocity. The plasma zones are investigated with a gated camera working in concert with a streak camera for Al, Nb, Cu, and W targets in Ar or Kr background gas. It is found that each plasma zone has a high density edge which is the origin of a plasma-generating electron jet leaving the target zone. Each region of strong azimuthal density gradient generates an azimuthal electric field which promotes the escape of magnetized electrons and the formation of electron jets and plasma flares. The phenomena are proposed to be caused by an ionization instability where each dense plasma zone exhibits a high stopping power for drifting high energy electrons, thereby enhancing itself.

Large-scale HI in nearby radio galaxies (II): the nature of classical low-power radio sources  

E-Print Network (OSTI)

An important aspect of solving the long-standing question as to what triggers various types of Active Galactic Nuclei involves a thorough understanding of the overall properties and formation history of their host galaxies. This is the second in a series of papers that systematically study the large-scale properties of cold neutral hydrogen (HI) gas in nearby radio galaxies. The main goal is to investigate the importance of gas-rich galaxy mergers and interactions among radio-loud AGN. In this paper we present results of a complete sample of classical low-power radio galaxies. We find that extended Fanaroff & Riley type-I radio sources are generally not associated with gas-rich galaxy mergers or ongoing violent interactions, but occur in early-type galaxies without large (> 10^8 M_sun) amounts of extended neutral hydrogen gas. In contrast, enormous discs/rings of HI gas (with sizes up to 190 kpc and masses up to 2 x 10^10 M_sun) are detected around the host galaxies of a significant fraction of the compac...

The price of electricity from private power producers  

Science Conference Proceedings (OSTI)

The long-term wholesale electricity market is becoming increasingly competitive. Bidding for power contracts has become a dominant form of competition in this sector. The prices which emerge from this process have not been documented and compared in a systematic framework. This paper introduces a method to make such comparisons and illustrates it on a small sample of projects. This results show a wide range of prices for what is essentially the same technology, gas-fired combined cycle generation. The price range seems greater than what could be explained by transmission cost differences between high and low cost regions. For the smaller sample of coal-fired projects, price variation is substantially less. Further data collection and analysis should be able to help isolate more clearly what market or cost factors are responsible for the observed variation.

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.

Producer gas power plants can cut the oil bills of the developing countries  

SciTech Connect

As a power-generation fuel substitute in developing countries, producer gas from coal, biomass, or waste could reduce oil-import bills while assuring a steady fuel supply. An international working group formed at the Royal Swedish Academy of Sciences is assisting developing countries in setting up simple producer-gas plants consisting of a downdraft gasifier, cyclone, filter, and cooler. Sweden gained expertise in this technology during World War II and now manufactures much of the equipment needed for producer-gas facilities. Depending on oil price, a dual-fuel power plant (15% diesel oil, 85% producer gas) could compete economically with a diesel-only plant, assuming extra labor requirements of 20 min/hr of operation for the gas-fired facility.

Easing the natural gas crisis: Reducing natural gas prices through increased deployment of renewable energy and energy efficiency

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 and energy efficiency identify these clean energy sources as an important part of the solution. Increased deployment of renewable energy (RE) and energy efficiency (EE) can hedge natural gas price risk in more than one way, but this paper touches on just one potential benefit: displacement of gas-fired electricity generation, which reduces natural gas demand and thus puts downward pressure on gas prices. Many recent modeling studies of increased RE and EE 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 and EE. This paper summarizes recent studies that have evaluated the gas-price-reduction effect of RE and EE deployment, analyzes the results of these studies in light of economic theory and other research, reviews the reasonableness of the effect as portrayed in modeling studies, and develops a simple tool that can be used to evaluate the impact of RE and EE on gas prices without relying on a complex national energy model. Key findings are summarized.

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.

Retrofitted feedwater heat storage for steam electric power stations peaking power engineering study. Final report  

DOE Green Energy (OSTI)

The technical and economic feasibility of retrofitting existing nuclear or fossil-fueled steam power plants with feedwater thermal energy storage (TES) systems for peaking power applications was investigated. A major objective of the study was to determine if retrofitted thermal energy storage (RTES) systems could result in significant fuel savings in oil- and gas-fired peaking plants. From this study it was concluded that RTES require high capital expenditure, excessive plant downtime for installation (16 mo for fossil-fuel; 24 mo for nuclear), that retrofitting 17,000 MWe of coal and nuclear plants would result in only about 2 percent annual savings in oil consumed by the U.S. utility industry in 1974, and that the technical questions which remain could best be answered by retrofitting a relatively new reliable plant as a test facility. The utility industry is receptive to the TES concept but not to the RTES concept. It is recommended that no further effort be expended on RTES, that TES studies should concentrate on coal and nuclear plants, and that a TES Proof-of-Concept Facility should be designed and constructed.

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.

System Definition and Analysis: Power Plant Design and Layout  

SciTech Connect

This is the Topical report for Task 6.0, Phase 2 of the Advanced Turbine Systems (ATS) Program. The report describes work by Westinghouse and the subcontractor, Gilbert/Commonwealth, in the fulfillment of completing Task 6.0. A conceptual design for critical and noncritical components of the gas fired combustion turbine system was completed. The conceptual design included specifications for the flange to flange gas turbine, power plant components, and balance of plant equipment. The ATS engine used in the conceptual design is an advanced 300 MW class combustion turbine incorporating many design features and technologies required to achieve ATS Program goals. Design features of power plant equipment and balance of plant equipment are described. Performance parameters for these components are explained. A site arrangement and electrical single line diagrams were drafted for the conceptual plant. ATS advanced features include design refinements in the compressor, inlet casing and scroll, combustion system, airfoil cooling, secondary flow systems, rotor and exhaust diffuser. These improved features, integrated with prudent selection of power plant and balance of plant equipment, have provided the conceptual design of a system that meets or exceeds ATS program emissions, performance, reliability-availability-maintainability, and cost goals.

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.

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%.

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. NETLs 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.

Evaluation of a superheater enhanced geothermal steam power plant in the Geysers area. Final report  

DOE Green Energy (OSTI)

This study was conducted to determine the attainable generation increase and to evaluate the economic merits of superheating the steam that could be used in future geothermal steam power plants in the Geyser-Calistoga Known Geothermal Resource Area (KGRA). It was determined that using a direct gas-fired superheater offers no economic advantages over the existing geothermal power plants. If the geothermal steam is heated to 900/sup 0/F by using the exhaust energy from a gas turbine of currently available performance, the net reference plant output would increase from 65 MW to 159 MW (net). Such hybrid plants are cost effective under certain conditions identified in this document. The power output from the residual Geyser area steam resource, now equivalent to 1437 MW, would be more than doubled by employing in the future gas turbine enhancement. The fossil fuel consumed in these plants would be used more efficiently than in any other fossil-fueled power plant in California. Due to an increase in evaporative losses in the cooling towers, the viability of the superheating concept is contingent on development of some of the water resources in the Geysers-Calistoga area to provide the necessary makeup water.
