ORNL Utility Survey

Subject: UFTO Note — ORNL Utility Survey
Date: Wed, 09 Jul 1997 11:49:03 -0700
From: Ed Beardsworth

The Engineering Technology Division at Oak Ridge sent out a survey to a list of utilities recently, with a cover letter from Ed Fox, the division director. Some of you have already seen it, and I have the names of who it was sent to in your companies if you want them.

The stated purpose is to increase utility awareness of ORNL R&D, to obtain feedback on the relevance to utilities of that work, and on priorities for additional R&D. Also, they want stronger ties to utilities and potential users of ORNL work…a goal certainly congruent with UFTO!

Ed Fox can be reached at 423-574-0355, ecf@ornl.gov

—————————–
1.0 PLANT/EQUIPMENT DIAGNOSTICS AND CONDITION MONITORING
The following technologies provide for monitoring the condition of machinery in service, on-line diagnostics for evaluating faults, plus R&D into effects of machinery aging. The objective is to relate appropriate maintenance or replacement actions to the actual condition of the machine.

1.1 Electrical Signature Analysis (ESA)
Data characterizing electrical currents and voltage waveforms to/from motors, generators and similar devices are obtained and recorded, using non-invasive probes. ORNL-developed analysis techniques are applied to the resulting data, leading to powerful insights into the health and performance of the electrical machine and the system and/or facility in which it is installed. A typical utility application involved the evaluation of transient loads in motor operated valves at a Carolina Power & Light nuclear plant. More recent developments include improved data analysis techniques and methods for the integrated monitoring of complete systems.

Status: Early forms of ESA are being used in a range of industrial applications, including utility power plants. Licensees include B&W/Framatome and ITT Movats/Westinghouse and Public Service Electric and Gas of New Jersey. More recent developments are available for licensing and/or joint development.

Previously aware of this research: _ Yes _ No
Request additional information: _
Relevance to current needs (please circle):
(Low) 1 2 3 4 5 6 7 8 9 10 (High)

1.2 Non-Intrusive Voltage and Power Factor Monitoring
ORNL is evaluating a series of new technologies for obtaining high voltage (>480V) waveforms and power factors, without contact and without the need for potential transformers. These technologies have significant potential in power quality monitoring applications.

Status: These technologies are in an early stage of development and evaluation. They are available for licensing and/or joint development.

1.3 Check Valve Monitoring
The function and health of check valves are evaluated, using a combination of magnetic and vibration sensors. Lack of adequate function and deterioration can be detected, without the need for removal or disassembly of the component.

Status: This technology has been licensed to several service vendors, including B&W/Fram- atome and ITT Movats/Westinghouse. Consolidated Edison is also a licensee.

1.4 Improved Eddy-Current Material Defect Detection
ORNL is developing a new technology for improved defect detection and imaging in non-magnetic materials. In laboratory tests, cracks in a perforated aluminum plate, located behind a 60 mil solid aluminum plate, are clearly imaged. In addition to aircraft inspection (the initial target for this innovation), steam generator tube inspection is a potential application of this new eddy-current based technique.

Status: This technology is in the early stages of development.

1.5 Effects of Aging in Machinery
ORNL has developed a vast database and associated reports on the effects of machinery aging. Information and expertise are available on the general principles of machinery aging as well as the specific effects of aging on individual components, machines and systems.

Status: The database was developed in support of NRC investigations into the effects of aging on nuclear power stations. It is available in the form of reports at the present time. Work is ongoing to develop methodologies to support condition based maintenance decisions.

—————————–
2.0 PLANT INSTRUMENTATION & CONTROL
ORNL’s capability for conceiving, prototyping and implementing advanced instrumentation and control (I&C) capabilities extends from the I&C support of experimental work throughout the laboratory and from supplying innovative sensor and control technologies to federal agencies, utilities and private industry. The following are examples of related utility applications.

2.1 Plug-in Compatible Instrumentation and Control Upgrades
ORNL has developed and prototyped a concept in which application-specific integrated circuits (ASIC’s) mounted on a motherboard replace corresponding analog modules originally installed in utility power plants. The simplicity of the individual ASIC’s reduces concern with common mode failures, a current issue with complex software driven systems. The resulting plug-in compatible replacement modules simplify installation and operation, because rewiring is not required and because changes to operating procedures are minimized.

Status: ORNL is supporting EPRI and the Westinghouse Owner’s Group in the advancement of this technology. A prototype safety system module has been fabricated and is currently undergoing testing.

2.2 Accurate On-Line Measurement of High Temperatures
ORNL has developed a technique for continuous in-situ calibration of resistance temperature detectors. The goal is to maintain an accuracy of 0.5% (°F) under actual operating conditions and to extend the range of useful measurement from about 900°K (1200°F), at present, to 1300°K (1800°F). A typical application would be measuring steam temperatures for on-line determination of plant efficiency.

Status: The technology has been developed to a pre-commercial form and feasibility has been established through demonstrations at the Diablo Canyon and Connecticut Yankee nuclear stations, as well as tests in the Kingston Steam Plant (EPRI I&C Facility).

2.3 Solid-State Hydrogen Sensor
ORNL and EPRI are developing a small, solid state hydrogen sensor for nuclear plant containment monitoring. Other utility applications might be in conjunction with hydrogen cooled generators, battery banks, etc.

Status: The sensor is patented and available for licensing. Tests have been conducted in air, nitrogen, argon, steam and transformer oil and for H2 concentrations of 0.5% to 30%.

2.4 Automated Measurement of EMI/RFI
ORNL has developed and used an instrument to monitor and record ambient electromagnetic interference/radio frequency interference (EMI/RFI) in power stations. The system is capable of non-obtrusive, unattended operation over several-month periods.

Status: Available now for licensing or use.

—————————–
3.0 NON-LINEAR TIME-SERIES ANALYSES
The catchy but misleading name “Chaos” has often been associated with a family of advanced non-linear time-series analysis techniques. In reality, these methods allow a degree of order to be
discerned for what otherwise appear to be a series of highly random events. Examples of practical utility applications are provided below.

3.1 Improved Combustion Control
Non-linear analysis can be used to analyze and optimize fossil power plant burners, fluidized bed combustion systems and, potentially, gas turbines for higher efficiency and improved NOx control.
Status: An early application was the characterization of fluid bed combustion systems, where an objective was to avoid unstable operating regimes (e.g., chugging). More recently, the potential of this technology for improving fossil burner control is being developed through a project involving EPRI, ORNL and B&W.

3.2 Failure Prediction
There is a further potential for applying non-linear analysis to advanced machinery diagnostics/ failure prediction (e.g., in turbine-generators). Bearings, in particular, appear to exhibit chaotic behavior in advance of certain failure modes.

Status: Non-linear analysis is being evaluated in conjunction with diagnostics and condition monitoring techniques, such as electrical signature analysis (see above). Westinghouse has expressed an interest in bearing diagnostics.

—————————–
4.0 TRANSMISSION AND DISTRIBUTION

ORNL is developing technologies for automating the control of transmission systems, increasing system capacity and providing an improved understanding of the underlying costs of ancillary services.

4.1 Real-Time System Control
ORNL, DOE and EPRI are developing the technology for real-time monitoring and control of widely distributed transmission systems. This compares with current practice in which responses to disturbances are predetermined on the basis of previously completed analyses. The real-time system will employ an array of monitors, with outputs time-synchronized by satellite clocks. Artificial intelligence techniques will be used to recognize and appropriately respond to disturbances.

Status: This work is in the early stages of development.

4.2 High Capacity Transmission
ORNL has participated in R&D for increasing the capacity of high-voltage transmission lines. Included was testing of a high phase order line, which has the potential for transmitting up to three times the power of a standard single circuit AC line.

Status: The potential of this technology has been confirmed through the operation of a 1.5 mile test section, sponsored by EPRI, DOE, NYSERDA, NYSEG and ESEERCO. Given the current transition to independent operation of transmission capacity, no follow-on work has yet been identified.

4.3 Cost of Ancillary Services
One challenge in establishing the pricing basis for open access to electrical transmission systems is placing a value on ancillary services (scheduling and dispatch, load following, system protection, VARs, energy imbalance, and real power losses). Initial estimates developed by ORNL range from $1.5-$6.8/MWh, with an average of $4.1/MWh. By contrast, the FERC pro-forma schedule includes an allocation of $1/MWh for ancillary services.

Status: An initial report, based on an analysis of 12 utilities is now available. Follow-on work is recommended to establish a consistent framework for estimates.

5.0 POWER ELECTRONICS
This area includes research in power electronics, which is finding broad applicability in power quality, energy conversion and storage, adjustable speed drives, transmission, links, etc.

5.1 Resonant Snubber Inverter
The Resonant Snubber Inverter (RSI) is a power electronics innovation that employs a special resonant circuit to reduce losses during switching. Tests at ORNL have shown efficiency to be improved by 15 percentage points at half speed and 5 percentage points at rated speed. Elimination of associated voltage spikes reduces voltage stresses (leading to higher reliability), and essentially eliminates electromagnetic interference. Potential uses include power conversion for energy storage devices (e.g., flywheels, ultracapacitors, etc.) and adjustable speed drives.

Status: The RSI is currently being developed at ORNL for a number of specific applications.. The technology is available for joint development and/or licensing.

5.2 Multilevel Converter
The Multilevel Converter is another power electronics innovation that allows synthesis of high voltage waveforms, using capacitors as voltage dividers. Potential applications include DC links, static VAR generators and high voltage variable speed drives, as well as power conversion from renewable energy sources (such as photovoltaic arrays) or battery-fed systems. The ORNL technology eliminates the need for transformers, which are a significant source of cost and energy losses in conventional systems. A problem with capacitor based systems is the tendency to develop an imbalance between voltage levels when real power is being transferred (this is not a problem in static VAR generator applications). The unique contribution of ORNL is a new approach for maintaining the desired voltage balance across the capacitors, when real power is being transferred.

Status: An 11-level (21-level phase to phase) multilevel converter, employing insulated gate bipolar transistors (IGBTs) is working in the laboratory at ORNL. This system is prototypical of a 60kV multilevel converter using gate turn-off thyristors (GTOs).

—————————–
6.0 INFORMATION MANAGEMENT AND OPERATIONS ANALYSIS
This area comprises R&D on information management and operations analysis methodologies which support the management decision process.

6.1 Integrated Operational and Economic Models
ORNL has developed an extensive capability for operations and economic modeling techniques that support the management decision process. Alternative courses of action can be evaluated on a probabilistic basis, taking into account both the likelihood of various outcomes and their technical and economic consequences. Typical examples in which utilities might apply such techniques include evaluating the business potential of a new energy storage device, or determining the likelihood that a nuclear facility would be profitable over its remaining lifetime.

Status: These modeling techniques have been extensively applied. A recent example is a probabilistic assessment (for DOE) of the economic viability of each of the nuclear plants currently operating in the U.S.

6.2 Real-Time Power Scheduling
ORNL developed a “Power Advisor” to guide the operations of the Paducah, KY uranium enrichment plant in response to real-time electric power pricing inputs. The model provides a basis for deciding whether blocks of power at a given price should be accepted or whether it is more cost effective to curtail plant operations. The model includes consideration of the technical limitations of the facility, as well as the economic impact on the product bottom line.

Status: In place and operating at Paducah, KY.

6.3 Performance Indicators
The performance indicator methodology developed by ORNL is an operations management process for filtering and organizing the vast amounts of data generated in a complex management environment. The key objective is to focus management attention on activities that have the most influence on organizational goals, such as economic return, operational efficiency, safety, etc. The process starts with the selection of key performance indicators. These individual measures of performance are subjected to additional analysis and weighting, resulting in composite indices representative of overall performance, analogous to a stock market index. Feedback mechanisms are included to optimize information flow and to respond to organizational changes over time.

Status: Currently employed by DOE for managing the DOE occupational safety and health program.

—————————–
7.0 UTILITY/CUSTOMER TECHNICAL SUPPORT
The following research areas would potentially support both utility and utility customer technology support needs.

7.1 Electric Machinery Analysis
ORNL has developed an improved motor equivalent circuit model to more accurately estimate the operating characteristics of electric motors. Input to this computer-based tool can start from name plate data and increased accuracy can be obtained with supplemental calibration measurements (e.g, speed and current). Once calibrated for a given machine, the method can be used to accurately predict loads, currents, efficiency, etc. As a result, the need for additional monitoring instrumentation may be reduced in some cases.

Status: The model is complete and available through the DOE Motor Challenge Program

7.2 High Temperature Thermography
Techniques developed by ORNL offer improved capability for accurately measuring high temperatures. Using emissions from thermographic phosphors, temperatures can be measured over a wide range (cryogenic to 1600°C [2900°F]) and without the need for physical contact.

Status: This technology has been applied to several industrial processes. Initial applications have included the first stage vanes of turbine engine gas generators and the surface of steel exiting a molten zinc bath in a galvanizing process.

7.3 Electric Machinery Test Facility
ORNL has developed a flexible and well instrumented Electric Machinery Test Facility. The current capacity is 100 hp, but is now being expanded to 700 hp. During testing, loads can be varied over a wide range. Input voltage and currents can also be varied to simulate various operating demands, as well as a range of power quality situations (e.g., voltage imbalances, harmonics, etc.)

Status: The Electric Machinery Test Facility is a National User Facility available for use by private sector entities for testing and qualification of motors, generators and related components at nominal cost.

7.4 Pump Test Facility
ORNL recently commissioned a Pump Test Facility, with a design capacity of 100 hp. The configuration of the facility is highly flexible in terms of flow configuration, installed components and provisions for instrumentation and monitoring.

Status: The Pump Test Facility is a National User Facility available for use by private sector entities for testing and qualification of pumps and related components at nominal cost.

7.5 Buildings Technology Center
ORNL is actively involved in developing technologies to improve the efficiency of buildings and installed equipment. The Buildings Technology Center (BTC), established at ORNL in 1994, includes a large scale climate simulator and a hot box for testing components (walls, windows, etc.), as well as facilities for testing equipment (e.g., heating and air conditioning).

Status: The BTC is a National User Facility available for use by private sector entities for testing and qualification of building components at nominal cost.

Happy NEW YEAR Topic Resource Files

 

Happy New Year! I hope your holidays were great.

1. We have a new member of UFTO. Pacificorp has decided to join. Welcome!

2. There’s progress in the high priority “By-Topic” mission we’ve set for this year. Enclosed is another cut & paste “Topic Resource File 1.0” report, this time on “Distributed Utilities”. Please pass it along as appropriate (note the upgraded format).

I’ve been fortunate to identify Fourth Floor Databases, a local company that’s been helping me to assemble the reports and to sort through alternatives for a long range solution

As you know, the two “1.0” reports were experiments to see what would be involved in cutting UFTO information along topical lines. The UFTO data is now in the form of a dozen separate word processing files (which I can send you if you want them–in MAC or PC format). This makes it awkward to search, scan and assemble topical subsets of the information. We basically did it “by hand” to make the 1.0 reports.

The approach that’s taking shape is a Filemaker database, where each record will contain a portion of text from the UFTO Reports and Bulletins, along with fields for source (lab), date, contact person and phone number. We’ll transform current text into discrete data records. The entries in “Distributed Utilities 1.0” are prototypes.

Filemaker works on either PCs and MACs, it’s easy to use, and it’s inexpensive. It also provides excellent searching capabilities. This will give us what I’m visualizing as an “automated cut & paste” capability. I can use it here to keep an up-to-date file of all the UFTO information, to produce Topic Resource Files at will, or simply to pull up every item on a given subject. If you want the capability at your desk, that will be easy to arrange.

How does this sound to you?

PLEASE– fill out the attached questionnaire and fax it back to me. Thanks

3. “Breakthrough Technology Conference” (Electrotechnology) in Tampa, April 24-6 — I hope you and someone from your marketing group will attend. We will hold an UFTO group meeting in conjunction with this event. See attached questionnaire.

4. 2nd Topical Conference — PNL has offered to work with us on arranging some kind of a meeting–and even to host it. Please indicate any prefences about time, place and topic — see questionnaire.

1 ORNL Organization
3. ORNL Technologies & Programs
10. ORNL Contacts

This report is proprietary and confidential. It is for internal use by personnel of companies that are subscribers in the UFTO multi-client program. It is not to be otherwise copied or distributed except as authorized in writing.

Summary
This report details findings about technology and technology transfer opportunities at the Oak Ridge National Laboratory (ORNL) that might be of strategic interest to electric utilities. It is based on two visits to ORNL in Oak Ridge, Tennessee (in November 1993 and March 1994), as part of a project for PSI Energy, which had the additional goal to establish relationships that will enable PSI to monitor developments and gain access on an ongoing basis.

Background
Noting the tremendous scope of research underway in the research facilities of the U.S. government, and a very strong impetus on the government’s part to foster commercial partnering with industry and applications of the technology it has developed, PSI Energy supported this project to become familiar with the content and process of those programs, and to seek out opportunities for collaboration, demonstration or other forms of participation that will further the business objectives of PSI. PSI has agreed to make these results available to the participants in UFTO.

ORNL Organization

Oak Ridge National Laboratory (ORNL) is a “GOCO” lab (government-owned, contractor operated). Martin Marietta Energy Systems Inc., a division of Martin Marietta Corp., is the contractor that manages ORNL and four other facilities, including the Y-12 Plant and the K-25 Site in the town of Oak Ridge, and gaseous diffusion enrichment facilities at Paducah (KY) and Portsmouth (OH). [Added Note: The recently announced merger of Lockheed and Martin Marietta is not anticipated to have any major impact on ORNL, except that over time there may be more joint activity with Idaho National Energy Lab. This is similar to the closer contact with Sandia that developed after Martin Marietta took over the management of that facility.]

Thus ORNL is a separate entity and organization from Y-12 and K-25, though they are all operated by the same management company. There are many overlapping activities, and some ORNL staff have their offices and facilities physically located at the other sites. For example, Y-12 is also the site of a joint program called “Centers for Manufacturing Technology” (Dave Beck is the contact), a manufacturing skills campus available to private industry on a full cost recovery basis. Thus, any interaction with ORNL will also provide a point of entry to the other Oak Ridge facilities.

Similar to other DOE labs, ORNL has a matrix organizational structure, where “divisions” aligned by discipline have the people, and “programs” have the projects and budgets. On some occasions, divisions do get funds and projects of their own. Overall, the matrix system is mature and functions very effectively at ORNL.

Both divisions and programs live in research “ALD’s” or Associate Laboratory Directorates, headed by Assoc. Lab Directors who along with other administrative and support groups report to the Laboratory Director (Alvin Trivelpiece).

ORNL’s four research ALD’s are:
– Physical Sciences & Advanced Materials
– Engineering and Manufacturing (name recently changed from “Nuclear Technologies”)
– Biomedical & Environmental Sciences
– Advanced Energy Systems

There is work in all four ALDs of potential interest to utilities. The point of contact for this study was established through the Energy Efficiency and Renewable Energy Program, which oversees activities involving 11 different research divisions. Contact was also made with the Fossil Energy Materials Program, with a similarly broad scope. Both of these programs are in the Advanced Energy Systems ALD.

ORNL also takes on a program management role nationally on behalf of DOE, for some aspect of a DOE program, e.g. supporting PETC or METC or the DOE program office directly, or in collaboration with other national labs.

Mechanisms to Work with ORNL

There are a variety of mechanisms for working with ORNL. The laboratory often subcontracts work to industry (usually cost-shared), and can also perform industry-funded work (but must demonstrate that it is not competing with other private industry companies).

One of the major mechanisms is the “CRADA” (cooperative research and development agreement), which is analogous to a joint venture between private companies. No money changes hands, but both parties bring something to the table, and get something of benefit from it, most typically intellectual property rights.

ORNL also has a number of “User Facilities” and “Centers” that focus on particular subjects, and make special equipment, facilities and expertise available to outside users, on a fee or collaborative basis.

One other general point: — the lab annually publishes an “Institutional Plan”, which is organized according to which DOE Program Office supports the work, not the lab’s own organizational structure. Thus a “mapping” between the two structures is required to be able to see the work of the groups within the lab. In most instances, divisions and programs also publish annual progress reports, providing detailed though not always current accounts of the work

Energy Efficiency and Renewable Energy Program
A.C.(Tony) Schaffhauser, Director, 574-4826. This office manages a wide spectrum of programs involving many functions and groups within ORNL.

• Power Systems Technology Program, James VanCoevering, Manager, 574-4829
OPPORTUNITY
ORNL has been active in T&D research since 1974, and handles all DOE work in T&D. “System 2020 Workshop” (Denver 1990) identified high priorities for T&D (DOE and utilities). ORNL focus is on high capacity transmission and power electronics. A complex organizational framework to coordinate initiatives has very little utility representation except thru EPRI and BPA & WAPA.

High Capacity Transmission Options: Goal is to develop new-construction options that increase power density on a corridor. Work is in areas of High-Phase Order and HVDC.

Real Time Control: They see T&D network as the world’s most complex process system, with trend away from “security by reserves” to “security by control.” Goal is zero reserve capacity — “N-1” criteria are expensive in terms of idle equipment. (Niagara Mohawk is only other utility representation on technical committee for this.)

High Capacity Power Electronics: Goal to reduce converter costs to make DC compete with AC at 150 miles instead of 400 mi.

Power Transients: Geomagnetic Induced currents and EMP/Lightning transients

Equipment Diagnosis: SF6 degradation detection — major CRADA, with work at NIST, Ontario Hydro and ORNL.

Reliability Centered Maintenance of T&D equipment — approach is to understand underlying physical processes, and acquire data on degradation processes. [Alternate approach would emphasize codifying “expert” experience.]

SMES Market Potential & Benefits for Electric Utilities: Extensive array of studies with utilities just getting started in early ’94, to examine various uses for SMES. Five under contract already, and 2 more in negotiation. AD Little did major evaluation of utility benefits for Storage and PLC.
[Anchorage Elec and B&W got $5 mil ARPA grant to design and build a SMES unit!]

• Superconducting Technology Program for Electric Energy Systems
Robert Hawsey, Director, 574-8057

In partnerships with ANL, LANL and industry. Issue quarterly bulletin. ORNL has advisory, study role, and receives 1/4 of the $20 million DOE budget. Doing work on motors, generators, transmission, but not bearings or current limiters. HTSC applications of greatest interest.

Interested particularly in adding inductor/reactors and transformers to the original list of applications of potential use to the utility industry. Also see SMES discussion above.

Looking for vertically integrated teams — “Partnership Initiatives” — 3 @ $2 million each, with a manufacturer, utility and laboratory. OPPORTUNITY

• Electric & Magnetic Fields Bioeffects Paul Gailey, Program Manager 574-0419

ORNL has lead role in coordinating DOE effort–program mgt., conferences, Q/A, publications, etc. on Engineering and Biological Effects. Good relations with EPRI. Also issue RFPs for DOE. Biology research looking for theoretical models, going outside of EMF community to main technical/academic societies (e.g. engineering study of current tomography of the human body).

Staff are urging more attention be given to what it would cost to mitigate EMF, for use in social risk/benefit decisions.

• Motors Ben McConnell, 576-2733

Motors themselves are already very efficient, and only small gains can be made. However, if the entire system (electric motor system — EMS) is taken into account, 30% improvements are possible. The entire system includes the power conditioning (ASD), the motor, mechanical drive/coupling, and the process device (e.g. pump, impeller, fan, etc.). The problem is that these are never looked at as a system, but as separate components. (Even in large companies involved in more than one area, the motor people don’t talk to the drive people don’t talk to the device people).

The “Motor Challenge Showcase” will start in ’94. Awards will be made to 5-6 industry teams, each to consist of a customer, a manufacturer, and a utility. A Notice of Program Interest (NOPI) is due shortly. Voluntary industry/government collaboration to promote efficient EMS; develop tools, protocols, guidelines; national EMS database and information clearinghouse.

• Power Electronics Technology Center William Key 576-0278

Advanced motor development, based on ultra centrifuge program. Axial gap permanent magnet; working with HTSC to see how to use it in motors.
(Note: referred by Ron Graves to Dan Linehan and John Conyer, ETD at K25, program development staff for adv. motors.

• Efficiency and Renewables Dr. George Courville 574-1945, Jeff Christian 574-9338

“Building Technology Center” is a “User Facility”, and has the recently consolidated activities related to buildings. There are major test facilities for heating, air conditioning, refrigeration, insulation and building materials. The also do performance analysis for Program Evaluation projects, and have a strong role in ASHRAE and ASTM standards, tests and procedures committees.

There are several technology developments also:

– Powder Evacuated Panels (PEP) insulates 5 times better than conventional insulation, or >R25 per inch. (It’s similar in structure to a package of vacuum packed coffee.) GE and Corning are vigorously pursuing applications, and ORNL’s role is on process and measurement improvements.
– Gas adsorption A/C — ORNL has basic patents on “triple adsorption”, licensed to Trane.
– Improvement for auto and window A/C–permitted 20% improvement in performance by overcharging the system while avoiding the “slugging” problem that usually results. It’s basically an liquid overfeed system, a separator/accumulator that keeps the liquid refrigerant from entering the compressor.
– High efficiency building block — a new geometry that reduces the front-to-back thermal bridging and amount of mortar that’s needed.
– Handbooks for Builders on building envelope, foundations, etc.

• Biofuels Feedstock Janet Cushman 574-7818; Lynn Wright; Robin Graham 576-7756

ORNL has managed the DOE’s Transportation Program’s work in crops and cropping systems for biofuel for over 14 years. (SERI/NREL handles the conversion technology.) An emphasis on ethanol is now broadened, with additional funding from DOE/EER and EPRI. Initially focused on crop yield research, there is now also work on demonstration and analysis (environmental CO2, economic development benefits, etc.)

Working with utilities on trees, especially interested due to opportunity to co-fire with wood, and “closed CO2 cycle” aspects. Also with ethanol producers and NREL. No plans to use existing forests, but need fuel while waiting for trees to grow. Ultimate objective is agricultural cropping. Doing project with TVA (Bruce Gold) and EPRI on cofiring woodwaste and crop residues, and resource assessment (economics, GIS/network model, etc.). Planting 1000 acre poplar farm in S. Minn., cofunded with EPRI, NSP and Minn. Power.

Species breeding — focus on poplars (hardwood). Best non-wood option is switch-grass–screening/breeding program at Purdue.

DOE/NREL recently released an RFP for feasibility studies of complete systems for biomass power and liquid fuels. (When making alcohol from biomass, 25% of mass is lignin, which goes unused unless it’s burned for power–i.e. power as a by-product–same idea would apply for paper mills.)

Ethanol producers formed a Consortium for Plant Biotechnology at Purdue, to use cellulose waste. (Involves New Energy of Indiana and ADM)

• Developing Country Program Thomas J. Wilbanks 574-5515

Developing countries experiencing very high growth rates, but face capital constraints for new capacity, e.g. explosive growth in appliances in China and India, putting pressure on power systems. Thus, utilities have to be innovative. Also, as they go to the world financial market, there are new pressures regarding the environment, growth, DSM, conservation, etc. They want U.S. experience to guide them, especially in management and organizational structure.

US utilities can get involved, and not just to make $$:
– Public service philosophy, especially to help stabilize the global environment!!
– Foreign situations offer a laboratory to test things
– Provides interesting careers for utility senior staff–good for morale
– Money available from US and international agencies.
-Can help with economic development back home.

“Joint Implementation” on Climate/Greenhouse gases — producers invest elsewhere to buy abatement credits (e.g. tree planting). TVA is helping fund IRP in China to open it up for Joint Implementation.

He’s working with EPRI/Wash DC office, and AID, World Bank, etc. Since ’82, more than 60 projects in 34 countries. AID setting up a “Sister Utility Program” with USEA.

Fossil Energy Materials Program
Rod Judkins, Director 574-4572. The Fossil Energy Materials Program is manager of the national program in materials development, which also involves 5 other labs and many contractors. They provide support to PETC Clean Coal and METC. They’re involved in bioprocessing and EIS/assessments for Clean Coal projects. In combustion there is work to evaluate fuels, and mild gasification (pyrolysis), and a CRADA with B:&W to study deterministic chaos theory applied to mixing of coal in FBCs.

There is also a User Center for Characterizing Materials.

Gas Clean-up with Ceramic Composite Filters (Dave Stinton 574-4556) They have a long history in CVD for coating nuclear fuel with continuous fiber ceramic composites, and are now doing chemical vapor “Infiltration”. A Nikalon fiber preform is infiltrated with CV Silicon Carbide, to make tougher high temperature materials impervious is breakage by thermal shock. Near term applications include filters for PFBC flyash and char. (Commercially available candle filters aren’t tough enough.) In work funded by METC, 3-M won the bid to commercialize, and is making 5′ candles prototypes, replacing the traditional clay or glass binder with CV Si Carbide, making it very resistant to corrosion. They performed well in tests by Westinghouse. (Not related to EPRI’s candle filter project in the U.K.)

Applications work on alloys, ceramics for corrosion problems: Iron Aluminide alloys have superb resistance to sulphadizing, e.g. in H2S in coal gasification (not the same as sulfates in combustion). Good structurally only to 600°C, but as a cladding to 1100 °C in sulfur environment and to 1300°C in an oxidizing environment.

An application has been developed to create a porous sintered filter metal. Amitech is the licensee for the invention, and makes the powder. In 1987, the Pall Corp. and Amitech entered into an informal collaboration with ORNL, and Pall is making filters from this material, and is replacing its own product on the market. The market is small currently, but since hot gas cleanup technology doesn’t exist–plants are designed more conservatively than may be necessary, particularly in the area of heat recovery. The technology may make 700°C flue gas cleanup possible.
OPPORTUNITY A utility could do the tests needed to go to the next step!

• Energy Efficiency Materials Program
Ron Bradley, Assoc Director, Metals & Ceramics Div. (MC) 574-6094
Michael Karnitz, Manager, Industrial Conservation Program, 574-5150
Philip Sklad, Manager, Adv. Industrial Concepts Materials Program, 574-5069

Metallurgy and Ceramics originally supported the nuclear program, but the scope has been broadened over time. Ron Bradley also is responsible for the Material Research activities in the Energy Efficiency and Renewables Program.

The MC Division has a budget of $60 million, almost all from DOE. It does both basic and applied research. About 1/3 is for energy efficiency, however none in solar PV, wind or geothermal.

Materials for Energy Efficiency: similar to the Iron Aluminide development, Nickel Aluminides came out of work on ordered inter metallic alloys, and have the interesting property that their strength increases with temperature! While they have good high temperature properties and oxidation resistance, they have poor sulphadation resistance. They do have applications in industry, such as heat treatment furnace components, and are being evaluated by Cummins under a license for turbocharger rotors.

Ceramics for automotive Gas Turbine–ORNL has managed the DOE effort for 10 years. Silicon Nitride ceramics have met the performance requirements for GT rotors, and the next issue being addressed is cost, and possible use in IC piston (diesel) and stationary GT for industry and utility use. (Allied Signal is already using ceramics for vanes in auxiliary power units for aircraft.)

A new program at DOE has been set up mid ’93 jointly by Fossil and Energy Efficiency, to develop advanced turbine systems, with efficiencies increased to 60% for large machines and into the high 40’s for smaller ones. (GE’s goal for 1998 is a new 250 MW turbine operating at 2550˚ C and 60% efficiency.) There are contracts in place with Allison, GE, Westinghouse and Solar Turbine, and possibly one with Siemens. ORNL’s role is materials support: coatings (silicon nitride), alloy development, machine characterization, ceramics for vanes, shrouds and uncooled blades.

A utility could become involved in possible application to GT/CC. There hasn’t been much interaction with EPRI, though Wate Bakker was testing the Iron Aluminide at Lockheed.

Corrosion in scrubber linings and coal powder abrasion are key issues for coal utilities.
ORNL had done a big review on corrosion 15 years ago, and couldn’t offer much at the time. Now, ceramic work tends to be aimed in different direction. Intermetallics a possibility–just learning how to put FeAl coatings down on steel, and NiAl would be ideal, but how to install? Aluminides being developed for gasifiers perform very well in high temperature sulfur environments–some common problems in DOE incinerator work.

Inorganic membrane technology from the isotope separation work is just emerging from secrecy. It has been licensed for some commercial applications, and there could be some intriguing possibilities of using it for hot gas separation in power plants.
