Electrochemical Ozone Generator

The usual method of producing ozone is by corona discharge in air. It requires auxiliary equipment to precondition the air (cooling to – 60 degrees C), it produces NOx and particulates, and it is limited to delivery of ozone at 2% concentration and atmospheric pressure. Despite these limitations, there is a rapidly growing use of ozone for laundries (hotels and hospitals especially), waste water treatment, and many other applications.

Lynntech, Inc, of College Station TX, is a multi-disciplinary technology development company established in 1990. To date, most of its revenues have come from SBIRs. The company has developed a range of new technologies which are in various stages of commercialization.

One of these new technologies is a patented electrochemical method of producing ozone, which overcomes many of the limitations described above. It introduces no impurities, requires no preparation of the air, and delivers ozone at 10-15% concentration at 30 psi or higher. Inherently simple with no moving parts, it can be scaled to very small sizes, allowing many new fields of use that aren’t practical with existing methods, including point of entry/use potable water treatment (e.g. bottled water production).

Lynntech is currently assembling pre-production units for testing by various customers. These cabinet-sized units will produce 5 pounds per day, and will be available in limited production quantities within a year. The company also has a one pound/day unit in prototype, and much smaller units are also envisioned. One patent is issued, and several more are pending.

The company is in the process of considering various options for business models to carry these developments forward, and would welcome discussions with interested parties.

**** “EOSystems — Electrochemical Oxidation of Hazardous Organics — benign on-site modular treatment, eliminating transport and incineration while building off-peak electric load. Also applicable to low-level radwaste volume reduction.” (UFTO Tech Nugget, August 1995) ****

UPDATE! There’s been considerable progress —

EOSystems, Inc. is commercializing a process for the destruction of both organic and mixed (hazardous wastes containing some level of radioactivity) organic wastes. They have recently obtained the first 20% of a $5 million private offering, and welcome inquiries by additional potential investors and other interested parties.

This is “electrotechnology” at its best. Significant for utilities, the process consumes considerable amounts of electric power, and this load can be shifted to off-peak times, making this a win-win-win for the utility, for the industrial customer, and for the environment.

EOSystems’ vision is to eliminate the creation, transportation and incineration of hazardous wastes by placing a unit at the site of every generator, from university labs to major chemical manufacturers and government facilities.

The Company has designed a proprietary reactor cell, which is the heart of the system. The cell is designed to be manufactured in volume from high density plastics, using advanced injection techniques, resulting in a system that is inexpensive to manufacture, service and replace. The engineering is being done jointly by EOSystems and Fluoroware, Inc., of Chaska, Minnesota.

EOSystems’ process is mediated electrochemical oxidation (MEO), for the destruction of hazardous aqueous organic process streams. The technology was commercially refined at both Pacific Northwest Lab (PNL) in Washington state and at Lawrence Livermore National Lab with a $4 million CRADA. The testing and prototype development have been completed by EOSystems and Flouroware with help from PNL. Controlled Power of Troy, Michigan, is aiding in the design and manufacture of custom power supplies.

EOSystems’ market is estimated at $200 billion in capital equipment sales to private and public laboratories, as well as chemical, pharmaceutical and semi-conductor companies. Manufacturers will employ EOSystems’ electrochemical oxidation in their processes to reduce or eliminate the creation of wastes which are currently difficult and expensive to handle and destroy (e.g., by incineration or landfill).

All wastes are fully contained until destroyed, eliminating costly downstream trapping required by thermal destruction processes. The system is also scalable to a customer’s process volume, and will match the specific constituent demands of each process stream, saving manufacturers even more in process costs while eliminating the liability associated with production of hazardous wastes.

EOSystems’ MEO is a very rapid, chemical, non-biological, step-wise dismantling of the organics, one electron at a time. It converts organics to carbon dioxide and water, using electricity to force a chemical reaction which picks up an electron from the organic, changing its chemical make up. The “mediator” is a metal ion in the solution; in this case the ion is cerium3+, which is exposed to an anode that removes an electron, changing it to cerium4+, an element now hungry for an electron. The cerium4+ is injected into a vessel containing the organics, where it sucks an electron from an organic, becoming cerium3+ again, and unbinding the organic so that it converts into carbon dioxide and water.

Summary

This report details findings about technology and technology transfer opportunities at the Lawrence Berkeley Laboratory (LBL)that might be of strategic interest to electric utilities. It is based on two visits to LBL in February and May 1995, as part of the UFTO multiclient project.

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, the UFTO program has been established as a multi-client study of the opportunities thus afforded electric utilities.

LBL Organization

Unlike the matrix structure common at other DOE labs, LBL has a straight line management organizational structure, and they’ve mostly eliminated (except on the administration side) the layer of managment known as “ALD’s” or Associate Laboratory Directorates seen at many other labs.

Nine technical divisions report directly to the Laboratory Director, C. V. Shank, and several others report to the ALD for Operations. There are also a number of Research Centers and User Facilities within the various divisions.

LBL is a major multiprogram lab managed by the University of California (as are Livermore and Los Alamos), with more than 3000 employees, a third of which are scientists and engineers. The annual budget is over $250 million. LBL is situated adjacent to the Berkeley campus of the University of California, and there is a great deal of collaboration and overlap between the two organizations. Many of the staff hold dual appointments, and UC graduate students often work in LBL programs (notably reducing the cost of research!). No classified work is done at LBL, so security is light, contributing to a campus-like atmosphere.

Administrative relationships can become quite complex. Projects, programs or “centers” may be either university or lab-based. One particularly noteworthy instance is the California Institute for Energy Efficiency (CIEE), which is actually part of UC’s quasi-independent Energy Institute, and until recently was funded by California utilities and state agencies. It is set up as a CRADA between LBL and the California utilities. Its technical resources could become more broadly available as they seek new roles and sources of funding.

Virtually all of the programs in the Energy and Environment Division are relevant to the electric utility industry, as are portions of other divisions(e.g. Materials, Chemical and Earth Sciences, and Information and Computing Sciences). Though the organizational structure is not ideally suited to cross-cutting activities, collaboration and joint efforts are not uncommon.

Within Energy and Environment, areas of interest include building energy efficiency, energy analysis, lighting technology, combustion cleanup, and energy conversion and storage. LBL has very strong programs in these areas, however the dissemination of results and interaction with industry has been somewhat limited, suggesting a possible underutilization of these resources by utilities which UFTO can help to overcome.

Generally speaking, much of LBL’s work in these areas tends to be informational or precompetitive. However there are also a number of specific developments underway with industrial partners, and some that could represent important strategic technology opportunities for utilities.

One other general point: each of the labs 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 a lab. In most instances, divisions and programs also publish annual reports, providing detailed though not always current accounts of the work

LBL Technologies & Programs

 

Topics Covered in this Report:

• Energy in Buildings

• Lighting

• Energy Analysis

• Environmental Research (Combustion and Air Quality)

• Information & Computer Sciences

• Materials Science

• Electrochemistry–Advanced Batteries and Fuel Cells

• Geothermal Energy

 

Energy in Buildings

LBL is particularly strong in work on Energy in Buildings from a number of points of view, in three distinct programs and a “Center”, plus the CIEE.

1. Indoor Environment Program, Joan Daisey, 510-486-7491
Ventilation, infiltration, ducts, efficiency in existing buildings, radon, indoor air pollutants, exposure and risk assessment, indoor air quality standards, etc.

• Duct Sealing Technology Mark Modera 510-486-4678, Max Sherman 510-486-4022

Energy losses from leaks in ducts are variously estimated to account for as much as 1/3 of the energy used in residential air-distribution heating and cooling. LBL has developed a technique for sealing leaks in existing systems. Analogous to “stopleak” used in automobile cooling systems, an aerosol is injected into the system which deposits itself at leaks, closing them off. Developed at LBL with support of CIEE, it is to be commercialized by EPRI, acting as a member of CIEE. (Agreements currently in negotiation.)

• Indoor Air Quality

Becoming more of an issue. Lawsuits more common. Standards being revised. Need better sensors for commercial use. Direct measurement more meaningful than specifying air change rates. LBL working on specific species, e.g. VOCs, CO, etc. Environmental Chambers allow detailed simulation and test of emissions from indoor sources.

2. Building Energy Analysis (in the Energy Analysis Program) Alan Meier, 510-486-4740
Data compilation, analysis of measured data (meta analysis across all available studies), assessment of efficiency impacts of technologies and programs, DEEP (Database on Energy Efficiency Programs), impact of high albedo surfaces, shade trees, etc., monitoring building performance, alternatives to compressive cooling, load shape estimation, urban climate, public housing.

3. Building Technologies Program , Stephen Selkowitz, 510-486-5064
Windows and daylighting, building energy simulation tools, lighting systems.

• Electrochromic Window Coatings (“smart windows”) can vary light transmission by from10-80% with the application of a low dc voltage; can be controlled to maintain constant light levels with dimmable electric lighting, control solar heat gain, and result in substantial overall energy savings and load control.

LBL is technical lead for DOE, and holds patents for two families of polymers for use in these coatings, and has CRADAs underway with Dow Chemical. Expect commercial prototypes in 2-3 years. Research field tests are already underway. There will be demos with utilities.

• Selective (“low-E”) Coatings pass visible light and block infrared. LBL doing research in the durability and performance of these coatings.

• Advanced Insulating Windows (“Superwindows”) include coatings and gas filled systems. LBL developed a concept which has been commercialized (with utility co-supported field tests

• Daylighting Design Tools

4. Center for Building Science , Evan Mills, 510-486-6784
A “home” for the three above programs, serving as a national and international source of information, technical support to policymakers, support to new institutions and demonstration programs, facilitate tech transfer.

5. California Institute for Energy Efficiency(CIEE),

Jim Cole, Director, or Carl Blumstein, Assoc. Director, 510-642-9588
This is a separate entity of the University of California — a collaborative of the California PUC and Energy Commission, the California electric and gas utilities, Universities, and LBL, focused directly at advancing technology for energy efficiency in California (all sectors) mid to long term.

CIEE may be an interesting target of opportunity to UFTO members. Its funding has been drastically cut — Calif. utilities are no longer paying dues. CIEE has funds to keep going for another 2 years, as it looks at alternatives for the future, one of which is to broaden its attention outside California.

CIEE may be a useful resource to utilities elsewhere, with its expertise and repository of technical information (available free). Also, there are ongoing projects which could be tuned or redirected to the interests of new players. As just one example, Building Performance Measurement, Operation & Control: Diagnostics for Commissioning and Operation has DOE support, and may be a “line of business” opportunity for utilities. An automated system is being developed that will help operators diagnose performance degradation, so that buildings can be operated “to spec”. There is also work in low NOx burners, alternatives to compressor cooling, HVAC distribution systems, and many other areas.

Lighting Systems, Francis Rubinstein, 510-486-4096

LBL is a lead player in lighting technology development, with its extensive R&D program in advanced lighting sources, fixture design, measurement, advanced controls, and education. (A detailed list of Publications of the Lighting Group is available. 510-486-5388)

For lighting, there are many different approaches appropriate in different applications and niches. There isn’t and won’t be a single “magic bullet” new technology. Utilities need to be informed about what is available on the market but is still underutilized (e.g. adv. controls, advanced compact flourescents, etc.) There are different solutions in different niches.

The state of the art in control systems doesn’t yet permit the specifying of useable systems that will achieve energy savings. This is a subject of particular interest at LBL, which is working with the NIST sponsored effort with ASHRAE standards committee to establish the “BACKNET” building automation energy managment protocol. LBL is also working with a utility and the GSA to propose a major advanced lighting control demonstration project in a Federal building. It is the area for utilities to get involved in, as relamping and reballasting become less interesting. Note that ESCOs can count on savings from relamping, but controls are unfamiliar, and can confuse their basic proposition of assured shared savings.

Utility Retrofit Energy Efficiency Program (UREEP): a new proposed program to support utility customer service programs with integrated training and education on advanced lighting retrofit. Will provide participating utilities with practical information and comprehensive guidelines and procedures to use with their customers. A number of utilities have already expressed interest in joining. Michael Siminovitch, 510-486-5863.

Sulfur Lamp: LBL is playing a major role in development and testing. The DOE press releases last year got a lot of attention, but this is still a long way from commercial availability. Generally, high efficiency comes with high intensity, so it means that a way to distribute the light from a single point (not just a fixture) is needed, thus the light pipe configuration. Demo applications/sites will be chosen soon. Interested utilities should contact LBL: Francis Rubinstein, 510-486-4096

Tests and Measurements: LBL has unique measurement programs and equipment, and can perform tests on prototype new lighting technologies. As one example, there is no data available on the angular sensitivity of photosensors, but LBL is performing these measurements. LBL won’t permit its name to be used for commercial testimonial purposes, nor will they compete with commercial test labs.

Advanced Lighting Guidelines: 1993 is a DOE report (DOE/EE-0008) provides an overview of specific lighting technologies and design applications for energy efficient lighting. The report assesses lighting strategies, discusses issues, and explains how to obtain quality lighting design and consulting services. Each of 10 sections provide a technology overview, discussing products on the market. For use by electric utility personnel involved in lighting programs, the report is also used at FEMP training sessions. (The work was cofunded by EPRI and the Calif. Energy Commission, each of whom also published the same document under their own respective covers.)

• PHOSNOX process, developed in 1990, removes NOx from Flue Gas simultaneously with SOx removal in existing wet FGD systems. NO is oxidized into more soluble NO2, by the addition of yellow phosphorus P4 to the scrubbing solution. Phosphoric acid is a recoverable byproduct. Process would be cheap and effective, but perceived safety issues have blocked further development. (Bechtel was actively promoting this for some time.) Ted Chang, 510-486-5125

• Iron Thiochelate is a more recent development addressing the same issue. The catalyst is added to the limestone in wet scrubbers to absorb NO. The catalyst is then regenerated as the bound NO is reduced to ammonia by electrochemical reduction [See Nature, v. 369, 12 May 94, p. 139.]. In mid May 95, a patent application was filed for a new simpler reduction technique, in which the liquor is passed through a column of Fe chips.

WANTED: a demo host, slip stream or pilot scale. Ted Chang, 510-486-5125

• Pozone uses yellow phosphorus in water to generate Ozone for bleaching paper pulp, and in other applications where the presence of phospate “contamination” isn’t an obstacle. International Paper is doing benchtests. Costs are estimated to be 1/2 to 1/3 (with credit for selling the phosphate byproduct) that of electrically produced ozone. Another possible application — regenerating active carbon that’s loaded with contaminants–could be done locally instead of at the very few licensed facilities. Ted Chang, 510-486-5125

• A novel catalyst offers a breakthrough in treating SO2 gas from coal-fired power plants, converting 98% of it to elemental sulfur. The Ralph M. Parsons Co. has just been granted an exclusive license. Ted Chang, 510-486-5125

Information & Computer Sciences, Stu Loken, Director 510-486-7474

This division includes both the operation of internal lab computer and information systems (technical and administrative information processing, and information services such as publications and the library) and research in information sciences, focusing primarily on network issues.

In this latter role, LBL has played a major part over the years in the formulation of the internet. In fact, TCP/IP traces back to LBL. The network research group deals with bandwidth allocation and scaling issues associated with the rapid growth in the size of the network.

The utility industry is expected to be a major player in the NII, because of the direct benefits to utilities and their customers. It’s already apparent that energy management programs and demonstrations will require such a large number of addresses on the network as to raise a problem that hasn’t really been addressed as yet.

In this light, LBL recognizes that its interactions with utilities have been too limited, and they are just beginning a process of self-education and outreach to the industry. They are looking for partners to work with them, particularly on integrating energy management equipment into network applications.

Materials Science, Joel Ager, 510-486-6715

High degree of involvement with industry, addressing fundamental materials development issues, e.g. high temperature superconductor sensors (squids), tough silicon carbide composites, ultra-hard coatings, crack-path prediction in layered structures, failure mechanism identification in nickel oxide scales (with EPRI), in-situ corrosion study of stainless steel (also EPRI).

 

The super-hard (diamond like) coatings can now be applied cost effectively on large objects (see UFTO Flash 3/21/95).

DOE Center of Excellence for the Synthesis and Processing of Advanced Materials (CSP), funded by the DOE Office of Basic Energy Science, is a network involving 12 of the major DOE labs, to support fundamental research and establish partnerships among the Labs, universities and Industry to shorten the time between development and applications. Steering Groups and a project plan exist for each of more than a 1/2 dozen topics, including Conventional and Superplastic Metal Forming, Materials Joining, Processing for Surface Hardness, and Mechanically Reliable Surface Oxides for High Temperature Corrosion Resistance, plus several dealing with microstructures. A 60 page description of the CSP is available from DOE. [I’ll obtain copies for anyone who wants one.]

 

Energy Conversion and Storage

LBL’s efforts in this arena are wide ranging, from advanced electrodes, to modeling, surface layer physics, and applied research in lithium and zinc based battery systems. There may be less of a place for direct interaction with utilities, as the work tends to emphasize research, not devices. LBL could be helpful, however, as an objective advisor to utilities about technology.
