Energy Storage

John Petersen After writing about investment opportunities in the energy storage sector for a couple of years, today marks an important transition because I've accepted Nadsaq's invitation to include my blog in the Community section of their website. I'm grateful for the chance to reach a broader audience and hope that my weekly musings can help new readers separate hype from opportunity and avoid the intellectual short-circuits that are all too common in the energy storage sector. By way of introduction, I'm a working lawyer and accountant who has spent 30 years guiding emerging energy and technology...

John Petersen On October 20th, Maxwell Technologies (MXWL) announced that it has commenced volume deliveries of BOOSTCAP® ultracapacitors to Continental AG (CTTAY.PK) for use in a new stop-start idle elimination system for diesel passenger cars made by PSA Peugeot-Citroen (PEUGY.PK). According to Continental, Peugeot-Citroen plans to sell about a million cars equipped with this technology over the next three years. While the Maxwell design win has been rumored for months, it's great to have confirmation that stop-start is here, it's now and it will become a major new energy storage market over the next three to five years....

John Petersen I've been writing this blog on pure-play energy storage companies for a little over two years. Initially I focused on broad themes like the importance of price and performance and the fact that every industry must master the baby steps before it can try to run. Over time the analysis got increasingly granular as I focused on individual applications instead of the industry as a whole. While I occasionally revisit basic themes like I did in last fall's Battery Investing for Beginners series, I worry that overly technical discussions of applications are not as useful for...

John Petersen In September I received an e-mail from France Innovation Scientifique & Transfert SA advertising their new IP Overview of Lithium Metal Phosphate Batteries - 2010/04. While I don't usually pay attention to e-mail pitches for costly reports, the FIST solicitation caught my eye because the abstract explained that roughly 1,100 patent applications have been filed for lithium metal phosphate chemistry since Dr. Goodenough's key patent issued in 1996. It's enough to give a guy a whole new perspective on this T-shirt from EV World. It also raises a couple critical issues that many...

John Petersen Quarterly updates are among my least favorite tasks because they focus on where the energy storage sector has been instead of where it's going. I still haven't developed a presentation format I like, but it feels like things are heading in the right direction. Reader comments and suggestions on how I can make these updates more useful are always appreciated. The 12-month performance for the energy storage sector was dismal and the only companies that currently trade above their September 30, 2009 closing prices are Active Power (ACPW) and Enersys (ENS). Most other companies in...

John Petersen Last week I spent three days at the 11th European Lead Battery Conference in Istanbul where I learned that I've been far too conservative in earlier articles that discuss the likely impact of stop-start idle elimination systems on the battery sector. To put things in perspective, the 10th ELBC in 2008 had 500 participants and two papers on stop-start systems. The 11th ELBC in Istanbul had 700 participants and 15 papers on stop-start, including three from major automakers. The stop-start papers took a full day of the 2-1/2 day conference program. The high-level overview...

John Petersen Many of my regular readers know I'm a working securities lawyer, a humble scrivener who writes reams of deathless prose that private companies use to raise money from investors, and public companies file with the SEC in the form of registration and proxy statements, and annual, quarterly and current reports. I've spent a couple years as an oil company executive and a few more as board chairman of an advanced lead-acid battery technology developer. The balance of my 30-year career has been devoted to natural resource and technology-based businesses that needed somebody elses' money to pursue...

John Petersen An English proverb teaches us to hope for the best but plan for the worst. With the imminent introduction of a variety of plug-in vehicles that will begin hitting showroom floors in the next few months, the phobia du jour is range anxiety, an entirely rational terror that an EV will get you to your destination in eco-chic style but only get you home with the help of a tow-truck. Sadly, most people who extol the virtues of electric drive are incurable optimists that have little or no regard for the risks inherent in complex systems...

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 Over the last couple years I've spent enough time in Asia to be fascinated by the growth opportunities and terrified by my own ignorance of the culture and the business dynamic. Since I know that I don't understand Asia, I tend to give Asian battery companies less attention than they deserve. Today I'll try to rectify that oversight. I'll also be adding New Energy Systems Group (NEWN) to my Chinese companies tracking list with a start date of June 30th. The first Asian company most investors think of when you mention batteries is BYD Co....

John Petersen Now that the earnings season is almost over, a review of surprises in the storage sector seems appropriate. Before digging into performance surprises, however, I want to share a surprising excerpt from "Reinventing Capitalism: How to jumpstart what the marketplace can’t," an interview with Bill Gates that served as the closing presentation at this month's Techonomy 2010 Conference. While I commend the entire video for those who have 50 minutes to spare, I was particularly intrigued by Mr. Gates response to a question about whether we could reasonably hold out hope that Moore's Law class gains...

John Petersen Last week I stumbled across a disturbing quote from Thomas Edison that was published in February 1883.   "The storage battery is, in my opinion, a catchpenny, a sensation, a mechanism for swindling the public by stock companies. The storage battery is one of those peculiar things which appeals to the imagination, and no more perfect thing could be desired by stock swindlers than that very selfsame thing. ... Just as soon as a man gets working on the secondary battery it brings out his latent capacity for lying. ... Scientifically, storage is all right, but,...

*with humble apologies to Charles Darwin John Petersen The Oxford Dictionary defines the adjective 'specious' as: Superficially plausible, but actually wrong; Misleading in appearance, especially misleadingly attractive. The Wiktionary offers a broader definition as: Seemingly well-reasoned or factual, but actually fallacious or insincere; strongly held but false; Having an attractive appearance intended to generate a favorable response; deceptively attractive. Over the last two years I've patiently analyzed the evolving price and performance forecasts of electric vehicle advocates and lithium-ion battery developers. In the process I've shown them to be possible, but unlikely, and...

John Petersen This Saturday marks the second anniversary of my blog, which began with an article titled Lithium-ion Batteries and Centerfolds. Over time my archive has grown to 142 articles on energy storage devices, the companies that make them and their crucial role as enabling technologies for wind and solar power, transportation and the smart grid. While cleantech bloggers usually focus on new technologies that might be game-changers, I'd rather focus on major enhancements to proven technologies from established industry leaders. The reason is simple, hot new technologies have limited investment value if the world can't produce enough...

John Petersen Most investors know that Toyota Motors (TM) is the world's biggest manufacturer of hybrid electric vehicles, or HEVs. Since 1997, Toyota has sold over two million cars using its Hybrid Synergy Drive® and earned a sterling reputation for fuel efficiency and customer satisfaction. What many don't realize is that Toyota is also the world's biggest manufacturer of advanced automotive battery packs. Toyota entered the battery business in 1996 when it bought a 40% interest in Panasonic EV Energy, a joint venture company that was formed to make NiMH batteries and battery packs for the Prius. Over...

John Petersen On Wednesday a reader sent me a new Goldman Sachs research report on the advanced battery sector titled "Advanced Batteries: Light, but the tunnel is long; Buy ENS, HEV Neutral, AONE Neutral." If the essence of legal argument is "the plausible boldly asserted," then I'd suggest that the essence of sell-side analysis must be "the implausible accepted without question." While I agree with Goldman's conclusions that Enersys (ENS) is a bargain at the current price and caution is best when it comes to A123 Systems (AONE) and Ener1 (HEV), I have major problems with their assumptions...
