Energy Storage

John Petersen On December 16th I wrote "My favorites for a strong 2012 include AONE, MXWL, AXPW.OB, ZBB, JCI, ENS, ACPW and XIDE. They all merit serious attention from investors who want exposure to the energy storage sector." Since then four of my favorites have bottomed and turned sharply higher while the Pride of Palo Alto endures a short circuit. The following table compares today's closing prices with the December 16th closing prices for those five companies. Exide Technologies (XIDE) has been a roller coaster over the last two years. In January 2010 its 10-day...

John Petersen I've been blogging about the energy storage sector since last July because batteries, single purpose devices that most of us take for granted unless they need to be recharged or replaced, are an essential enabling technology for cleantech, the sixth industrial revolution. With this week's impressive launch of A123 Systems (AONE), the tsunami of investor interest I've been predicting since last fall has finally arrived. Since the A123 Systems IPO has introduced an entirely new class of investors to the energy storage sector, this seems like a particularly good time to go back to square...

John Petersen This morning Reuters is reporting that A123 Systems, Inc. (AONE) increased the number of shares offered in its IPO from 25 million to 28.1 million and sold those shares at a price of $13.50. If the underwriters exercise their overallotment option, which is usually the case in IPOs of this size, the total IPO proceeds will be $437.5 million before costs, commissions and discounts. This IPO has been a long time coming but it was worth the wait. I want to congratulate the A123 team and the underwriters on a job well done. Assuming full...

Tom Konrad CFA A123 Systems battery cell products (Source: A123)  It was no secret that A123 Systems (NASD:AONE) was desperate for money.  It’s also no secret that Chinese companies are interested in buying Western companies, especially when they can acquire useful technology in the deal.  So this morning’s announcement that Wanxiang Group Corporation, a Chinese largest autoparts manufacturer which has significant US operations, had signed a non-binding memorandum of understanding to invest up to $450 million in A123 through a combination of bridge loans, convertible notes, and warrants seems...

Penn State researchers are finding new ways to harness the power of the sun using highly-ordered arrays of titania nanotubes for hydrogen production and increased solar cell efficiency.

This May will mark the nine-year anniversary of "Costs of Lithium-Ion Batteries for Vehicles," a seminal study from the DOE and Argonne National Laboratory that sent America lurching down a path toward an HEV, PHEV and EV future based on Li-ion batteries. Since nine years is a respectable length of time in most industries, I thought it might be interesting to review the prevailing expectations in May of 2000, consider the cost reductions achieved over the last nine years and question whether the market frenzy over Li-ion battery companies is even close to rational. Regular readers know that I'm...

John Petersen In the wake of last fall's initial public offering by A123 Systems (AONE) I wrote a four part series on battery investing for beginners. Over the last six months, changes in the storage sector have been coming at a fast and furious pace and many of my recent blogs have focused on technical minutiae rather than the stock market. They've led to heated debate with die hard EV advocates who don't understand the difference between technical and economic reality and religious belief, but I'm not sure how useful they've been for investors who see the potential...

John Petersen In 1789 Benjamin Franklin wrote "in this world nothing is certain but death and taxes." Today he probably would have written "in this world nothing is certain but death, taxes and rising oil prices." There's no escaping the misery, but astute investors who take the time to understand the fundamental trends can profit as the misery unfolds. For the short term, I'm convinced the biggest opportunities will be in fuel efficiency technologies for cars and light trucks. After 20 years of complacent stagnation, the US started to get serious about light-duty vehicle fuel efficiency in...

John Petersen If EV evangelists have everything their way and lithium-ion battery developers can achieve their lofty cost and performance goals, your long-term future may include a car with a plug. While we wait for that glorious day to arrive your short-term future will almost certainly include a car with stop-start engine technology. The issue is simple – sitting at a stop light with the engine running wastes fuel and fouls the air. Depending on traffic, weather and driving habits, the waste can range from 5% to 15%. On a personal level the waste may seem modest,...

John Petersen I've been writing about micro-hybrid vehicles and stop-start idle elimination since May 2009. It's a cheap and simple fuel efficiency innovation that turns the engine off while a car is stopped at a light and automatically restarts the engine when you take your foot off the brake. It's not gee-whiz sexy, but it can boost fuel economy by 5% to 15% in city driving and dramatically improve urban air quality by reducing idling. What could be more sensible? When I first wrote about stop-start in "Why Advanced Lead-acid Batteries Will Dominate the HEV Markets," the...

Beacon Power Corp (BCON) reported revenue of $304,064, compared to revenue of $80,902 in the third quarter of 2004, an increase of $223,162, or 276%. Revenues for the nine months ending September 30, 2005, were $1,258,503, compared to $264,793 for the same period in 2004, an increase of $993,710, or 375%. Beacon Power reported a net loss of $2.1 million, or ($0.04) per share, compared to a net loss of $1.9 million or ($0.04) per share for the third quarter of 2005 and 2004, respectively, representing an increase of approximately $0.2 million or 16%. They ended the...

Tom Konrad, CFA NiMH battery company that's going to "make coal and oil obsolete" sleuthed out. I can't help but chuckle at the hyperbole of some promoters of alternative energy stocks.  We can wish that coal and oil will be obsolete tomorrow all we want, but it ain't gonna happen.  That's just what Nick Hodge was claiming in a recent teaser for Highpower Technology (HPJ).  How do I know it's Highpower that Hodge is hailing as the answer to all our hopes?  Because Travis Johnson, the Stock Gumshoe told me so.  Travis is the same...

Doug Young A123 Systems battery cell products (Source: A123) In writing this blog, I generally try to keep my own views muted and focus instead on the latest news and what it means for the companies involved. But I'm making one of my occasional exceptions to that rule today to say that the US really should go ahead and approve the sale of bankrupt battery maker A123 Systems (OTC:AONEQ) to a Chinese company, since this deal seems to have few if any national security implications and blocking...

John Petersen For over a year I've been cautioning readers that while lithium-ion batteries are glamorous, sleek, sexy and hot; they are about to face a formidable challenge from lead-carbon batteries that are a little bulkier and heavier, but offer competitive cycle-life and power for a tiny fraction of the cost. To placate lithium fundamentalists and EV evangelists, I want to clearly state up front that lead-carbon batteries will probably not be the first choice for plug-in vehicles. Nevertheless, it is crystal clear that lead-carbon batteries will be the only sensible choice...

by Debra Fiakas CFA Last month BioSolar (BSRC:  OTC/PK) reported positive test results for its proprietary energy storage technology.  The company is developing an alternative anode material for lithium ion batteries using silicon-carbon materials.  BioSolar’s engineers are targeting dramatic improvement in anode performance and equally impressive reductions in cost.  If they are successful, it could mean longer lithium ion battery life, greater capacity and shorter charging time  -  the dreams of every manufacturer with an electronic product. Most lithium ion batteries rely on graphite for the battery anode.  However, silicon anodes could offer as much as ten...
