"brrrrp --- excuse me,
but what are you guys talking about?"
~ in a nutshell,
last week, PCE.au, (the original/exclusive owner of the vrb tech up until the "One Cent Solution" was finalized (april/05)), was re-badged as Cougar Energy (CXY.au), and is now concentrating it's efforts in the area of Underground Coal Gasification (ucg) in outback Qld. Oz. under the good doctor - Len.

there appears to be some notion afoot, that there will be some synergies between the on-site gas turbine production of electricity and vrb storage of same.
so much for (pe)nuts, eh rosie.

Increasing conflict in the Middle East and the shutdown of a large oil pipeline in Alaska sent Wall Street lower last week. The broad market declined 3.9%, which provided most of the negative momentum for Darnell's Power Index (DPI). While DPI dipped 2.3%, it outperformed the market primarily based on strength in the power conversion sector, which was up 0.8%. The power semiconductor sector nearly mimicked the broad market with a loss of 3.8%, and the energy storage and generation sector (ES&G) succumbed to a 5.5% loss.

Delta Electronics, CEAG and PowerDsine lifted the power conversion sector last week. Delta announced July sales revenue increased 39% to $267.0 million, which brings cumulative year-to-date revenue to $1.7 billion, up 44% compared to last year. Delta's growth continues to occur throughout its business lines, and the company's power products continue to contribute approximately 55% of revenue. As a result of this positive news, shares of Delta traded 5.8% higher.

CEAG, the parent company of external power supply producer Friwo, saw shares climb 5.1% on news that half-year revenues were up 64% to $196.7 million. The primary growth driver was stronger-than-expected sales of external power supplies for mobile phones. The company claims unit sales for mobile phones grew 50.6%, reaching 131.0 million units. However, revenue growth outpaced unit sales growth as Friwo continues to shift production lines to switching power supplies.

PowerDsine jumped 10.4% higher on continued momentum built following the company's financial release at the end of July. Thus far through August, the company is up 22.3%, which is the largest gain by any DPI company by nearly a factor of two. Cherokee International made a smaller gain of 0.8% after announcing that it will close its manufacturing plant in Mexico as it transfers production to a new facility in China. This move is expected to reduce costs in the range of $1.7 million to $2.2 million annually.

While chip stocks as a whole followed market trends, IXYS, Micrel Semiconductor, Monolithic Power Systems, ON Semiconductor and Semtech delivered losses larger than 8.0%. Monolithic Power systems fell 8.2% after Linear Technology filed a breach of contract and a patent infringement suite against the company. Shares of Linear traded 3.1% lower during the week. ON Semi fell 10.6% as its largest shareholder, private equity company Texas Pacific Group (TPG), sold 30 million shares. This takes TPG's holding in ON down to 39.8% from 49%. As a whole, the chip sector had a fairly quiet week except for the normal smattering of new product releases.

The ES&G companies are typically among the last to report quarterly results. Last week, six of the 19 companies reported and all but four of the ES&G companies were down. The four companies, Ballard Power Systems, BYD Company, Exide Technologies and Valence Technology, each made modest gains. Exide rose 1.3% after posting sales of $683.2 million for the quarter, up 2.1%. Valence reported sales of $3.2 million, down 5.8%, but the company was able to reduce its loss by 30% to $5.7 million. As a result, Valence shares traded 3.1% higher. On the other side of the market, Beacon Power dropped 7.1% after announcing that quarter revenue was $0.2 million, down 34% from the same period a year ago. SatCon Technology dropped 14.8% after announcing a modest decrease in quarterly revenue to $8.1 million.

What few of these articles mention is that the energy (and associated environmental disruption – entropic change) that goes into creating the system has to be factored into the overall energy balance. This is how the sustainability of a system can be determined – by its comprehensive life-cycle cost using a broad analytical system boundary. Otherwise you are just considering input/output operational efficiency. And if we are ever to live in a truly sustainable manner the metrics of economic efficiency and thermodynamic efficiency will have to converge.

[b]Lithium Ion Nanoparticle Batteries Better For Cars[/b]

An article in Technology Review reports the Altair Nanotechnologies lithium ion battery has the fast charging and discharging needed for all electric vehicles.

Advances in lithium-ion battery technology over the last few years have experts and enthusiasts alike wondering if the new batteries may soon make high-performance electric vehicles widely available. Now one company, Altair Nanotechnologies of Reno, NV, has announced plans to start testing its new batteries in prototype electric vehicles, with road tests scheduled to begin by year-end.

The batteries can be recharged in 6 to 8 minutes.

Also, Gotcher says an electric vehicle using their batteries could charge in about the time it takes to fill a tank of gas and buy a cup of coffee and snack -- six to eight minutes.

...

Gotcher says the new battery materials can be produced for about the same cost as conventional lithium-ion materials, but will have two to three times the lifespan of today's batteries.

Lithium is lightweight. Lithium-based batteries could make electric cars feasible.

Nanoparticles that provide much more surface area allow the batteries to charge and discharge much more rapidly.

The added surface area of nanoscale particles on electrode materials helps the ions escape, freeing more of them to travel and provide bursts of power or quick recharging.

Some electrochemists think lightweight high energy density batteries are within the realm of the physically possible. Development of long lasting, quick charging, cost competitive, and lightweight batteries could make electric cars commonplace. Such a development would greatly reduce our dependence on oil and allow any energy source that can produce electricity (e.g. nuclear, coal, wind, solar) to replace oil for most transportation needs.

An EE Times article from 2001 surveyed the field of battery development and experts think batteries viable as automotive power sources are still years away.

Similar efforts are in progress at Massachusetts Institute of Technology (MIT), where researchers have developed a competing lithium-polymer battery that could ultimately achieve energy densities of 300 W-hr/kg, according to its developers. The technology, which uses a multiple-layer configuration of polymer and metal resembling a potato chip bag, is funded by the Office of Naval Research and is said to be 5 to 10 years from commercialization.

That article does a good job of describing how far a battery technology would have to advance in order for it to become competitive for automotive applications. The MIT effort, if successful, would create batteries that would have about 4 times more power density than the nickel-metal hydride batteries found in the most expensive uncompetitive electric vehicles (whose market prices are way below manufacturing costs btw). That would make the batteries dense enough. The cost is a question though.

THE MARKET for Reliable Electicity Storage
==========

Backup energy for telecommunications

The convergence of voice and data communications over both wireline and wireless mediums is leading to unprecedented requirements for power use and power backup. Third generation (3G) telecommunications (telecom) networks are expected to carry voice and data 40 times faster than the current networks. For cable and telecom services every time an operator adds a new service offering high-speed data or telephony or adds subscribers to those services, there is an impact on network power. Also, there is an increasing recognition of the relationship between the power component of a given system and overall network reliability. These are expected to demand new rechargeable batteries with enhanced performance capabilities of higher energy density and longer backup service.

Traditional telecom architectures use 48 V direct current (DC) systems to provide resilient power for voice transmission. Normally power is accessed from electric utilities via AC-DC converters. For power backup during electricity outages 48 V batteries are used. Telecom hotels employ both flooded and sealed VRLA Lead-acid batteries; for the outdoor cabinets backup is provided almost exclusively by the VRLA battery. Typically, batteries in these outdoor cabinets are required to provide up to 8 hours of backup power. In wireline, for example, 48V 30-125 Ah batteries are frequently used in the DSL cabinets in the field. While maintenance issues necessitated the exclusive fielding of sealed VRLA batteries in outdoor cabinets, the fluctuating temperature environments of the cabinets have created serious concerns of battery life, and safety issues. The performance of VRLA batteries deteriorates drastically as the environmental temperature increases beyond 30 oC. Unfortunately in some outdoor cabinets temperature can increase to as high as 50-55 oC which seriously decreases the life of the VRLA battery. Higher temperature can also lead to gas pressure buildup in the battery causing explosion and fire. Another issue with Lead-acid batteries is its large volume. Space is premium in outdoor cabinets. Telecom operators would rather use the space to house revenue-producing telephone equipments than batteries. These factors coupled with increasing power requirements for enhanced services are requiring telecom providers to come up with advanced battery solutions having significantly more energy content per unit volume and longer service time.

Modular Energy Devices offers a series of superior batteries for these backup energy applications. ModEnergy® Lithium-ion batteries occupy 1/3rd to 1/4th as much space as the Lead acid batteries, are less sensitive to temperature excursions with an ability to perform at temperatures as high as 50-60 oC and are available at a price that is competitive with Lead-acid when prorated for useful battery life. They are highly reliable and safe.


:: Uninterruptible power supplies (UPS)

Utility companies use VRLA batteries as UPS systems to provide back-up power for switchgear equipment and other critical loads. Switchgear enables utilities to bypass localized outages ( e.g. failed transformer or downed cable) and to provide power to the other parts of the grid. Critical loads include computer centers, banks and other financial institutions, air traffic control centers, various government agencies and stock exchanges. UPS applications utilize 120-240 V VRLA batteries with capacities ranging from 200-1000 Ah

Modenergy® Li-ion batteries are clear choices for the UPS applications because of their significantly higher energy density, reliability, temperature compliance and safety.



:: Electric, hybrid electric and fuel cell vehicles

A continuing global concern into the twenty-first century is the reduction of airborne pollutants, especially in large urban centers. The combustion engine vehicle has been identified as a major contributor to air pollution and global warming effects. Pressure to develop a zero-emission replacement for the internal combustion engine has been fueled by California¡¦s Zero Emissions Vehicle (ZEV) legislation. The legislation has two phases. In phase one; beginning in 2003, ZEVs must comprise approximately 2% of automakers¡¦ total vehicle sales. In Phase II, beginning in 2010, this target level is increased to approximately 10%. Failure to meet these target levels will result in stiff financial penalties. Adding to the pressure on automakers to meet this deadline are copycat bills in Massachusetts, New York, and Vermont that will require automakers to sell ZEVs in those states if California goes ahead with its initiative. Many other countries have been already providing incentives to those who use clean energy. For example in Great Britain there are tax incentives and special privileges for owners of zero-emission vehicles. Currently, the only zero-emission vehicle alternatives are the battery electric and fuel-cell electric vehicle.

A hybrid-electric vehicle, which combines a small combustion engine for cruising power and a battery to aid in acceleration, is an efficient, intermediate solution until a true zero-emission vehicle can be introduced. All of the major carmakers (GM, Ford, Toyota, Honda¡K) are producing, or have announced plans to produce hybrid electric vehicles. Many fuel-cell vehicle developers have now adapted the use of a battery and fuel-cell combination to reduce the peak power requirements on the fuel-cell converter. Fuel cell vehicles also have future potential as a zero-emission vehicle, and all the latest models have evolved to operate in Hybrid-Electric mode, where the fuel-cell system provides cruising power while acceleration is aided by a battery pack. Batteries are also critical for providing the significant starting and heating power for the fuel-cell plant.
