John Petersen In November 2008 I wrote an article titled "Alternative Energy Storage: Cheap Will Beat Cool" where I created a short list of 13 pure play energy storage companies that I divided into two classes; companies with cheap chemistries and companies with cool chemistries. My premise was simple, the best affordable technology always wins out over best available technology and companies that cater to the masses have greater profit potential than companies that cater to the elite. The following graph compares the performance of my original groups and the Dow since the date of that article. ...

John Petersen I usually write a quarterly recap to summarize what happened in the energy storage and vehicle electrification sectors, but Q2 was a tough enough period that I don't see much sense in dwelling on the bloodletting. So instead of focusing on the past, I'll offer a quick summary table with lots of red ink and turn my attention to Q3, which is shaping up as a time of bright opportunity for some companies and profound risk for others. I expect three companies in my tracking group to perform very well in Q3 –...

Two diametrically-opposed stories for this post: Beacon Power and RailPower Tech . The latter is up 134% on its week-ago closing price, while the former is down nearly 22% over the same period. Beacon Power Corp I wrote about Beacon Power a little while ago. The recent drop in share price is due in large part to the fact that Beacon announced, last Friday (Dec. 29), a glitch at one of its testing facilities in Massachusetts. This was followed by an analyst at Merriman Curhan Ford downgrading the company from Buy to Hold. Almost immediately, the...

Beacon Power Corp (BCON) announced that it has delivered a flywheel-based power system to Bechtel Bettis, Inc., under a contract that it announced in March 2005. The demonstration system, built using a Smart Energy 6 flywheel, is designed to provide a high cycle-life, reliable source of stored energy for a number of potential applications. "This system we've delivered to Bechtel Bettis is an example of our strategy to address additional market opportunities beyond our primary business focus of providing advanced technology solutions for electric power systems," said Bill Capp, Beacon Power president and CEO. "We continue to seek...

by Debra Fiakas CFA   Diagram of a battery with a polymer separator. Lithium ion batteries make it possible to recharge your smart phone, camera and a multitude of other have-to-have-with-us-every­-moment devices.  Yet the average person knows very little of the inner workings of something so important to our daily lives.  One little item in a battery is a highly specialized membrane that fits neatly between opposing electrodes  -  the positive and negative poles that make an electrical charge.  This membrane manages the charge and discharge process. ...

Active Power Inc (ACPW) announced that it successfully operated a prototype of its new battery-free energy storage system at 10 kilowatts (kW) for over 2 hours, a milestone that positions the new product well for the telecommunications segment. "The runtime of this prototype system is already 60 times that of our flywheel product and yet offers the same battery-free benefits," stated Joe Pinkerton, Chairman and CEO of Active Power, Inc. "A battery-free system that provides hours of backup time will allow Active Power to pursue the $4 billion telecommunications backup power market."

by Debra Fiakas CFA While the rest of the battery industry is trying to perfect new technologies, Axion Power International (AXPW:  OTC/QB) has been working on a fix for conventional lead acid batteries.   Low cost made the lead acid batteries popular even from the early days when a French scientist first introduced the configuration in the mid 1800s.  Lead-acid technologies represent about half of batteries made today.  Unfortunately, lead-acid batteries have low energy-to-weight and volume.  Storage times are limited.  They also have corrosion problems.  The active materials in lead-acid batteries change physical form during charge...

Li-ion Motors. (HYBT) has inked a deal with Frito Lay to provide Hybrid Technologies' Lithium vehicles as part of their fleet sales program. Frito Lay has agreed to purchase and take delivery of the Lithium Mini Cooper model as well as the Daimler Chrysler Smart Car Lithium version. The first deliveries are scheduled for the first quarter of 2006. These vehicles will be part of Frito Lay's Hybrid fleet and the corporation's commitment to "green philosophy" as well as its well known philosophy of working with the latest in American technology. You would have thought that...

John Petersen Today is the fourth anniversary of my blog on investing in the energy storage and electric vehicle sectors. Over the last four years I've penned 275 Articles and 45 Instablogs on topics ranging from technical minutiae to broad macroeconomic trends. Since most of my work focuses on challenges and risks instead of lofty and optimistic goals, I'm often derided as a curmudgeon who doesn't understand the dream. Truth is I've been a guide in the Valley of Death for over thirty years and while I love panoramic scenery, I can't overlook the dangers of old mine...

by Debra Fiakas CFA Cars powered by fuel cells or batteries are only as clean as the electricity used to produce the power source.  Proponents of hydrogen fuel cells argue that fuel cells have an edge over batteries, because hydrogen can ultimately be made cleaner with innovations in hydrogen production.  Steam reforming of natural gas is the most common source of hydrogen and for the most part it is still the most cost-effective process for large-scale production of hydrogen.  Since ethanol is a renewable resource, the steam reforming of ethanol has been proposed by some as...

Arotech Corporation (ARTX) announced that its Battery and Power Systems division has received additional funding from the U.S. Army's Communications and Electronics Command, CECOM, for further development of its 4th generation (Gen4) zinc-air cells. The funding covers Phase II of a three-phased research and development program for Gen4 Zinc-Air Cells aimed at the Future Force Warrior project - the U.S. Army's flagship Science and Technology initiative to develop and demonstrate revolutionary capabilities for Future Force soldier systems. Arotech's Gen4 portable battery pack is 12 or 24 Volts and has a total capacity exceeding 400Wh with Battery Energy Density above...

Beacon Power Corp (BCON) announced that on March 2, 2005, it received a letter from The NASDAQ Stock Market stating that because the closing bid price of the Beacon's common stock has been at $1.00 per share or greater for at least 10 consecutive business days, Beacon has regained compliance with Marketplace Rule 4310(c)(4). This is wonderful news for BCON.

John Petersen Over the last couple of years, the mainstream media has been awash in reports of how automakers are lining up to build fleets of PHEVs and EVs using lithium-ion batteries as a principal power source. I've consistently argued that investing in objectively expensive lithium-ion battery company shares on the basis of testing decisions was dangerous. The reason for my caution is simple, a decision to test a new concept is very different from a decision to commercialize a proven concept and failures in the preliminary testing stages are far more common than successes. In...

John Petersen In November 2006, a slick issue-oriented documentary asked the provocative question "Who Killed the Electric Car" and argued that General Motors' EV1 project was terminated because of collusion between the auto and oil industries. The truth is nobody killed the electric car. It died in infancy from congenital birth defects and the same flaws that killed the EV1 will probably kill Tesla Motors, Fisker Automotive, Nissan's (NSANY) Leaf and GM's Volt. This is not a question of cost, performance, abuse tolerance or cycle-life. It's a fundamental flaw in the economics of using batteries to replace a...

Tom Konrad CFA  A123 Systems battery cell products (Source: A123) A123 Systems′ (NASD:AONE) announcement of a new battery technology able to operate at both extremely high and low temperatures has the  headline writers dreaming of cheaper electric cars. Electric cars may be dreamy, but they are just one application of the technology.  There are at least two more, with significant near term potential. 1. Is it really about electric vehicles (EVs)? Sure, it would be nice to be able to trim $600 of the price tag of a Tesla (NASD:TSLA) Model...
