Energy Storage

John Petersen On June 22nd Scientific American rolled-out a Web-only article titled "The Dirty Truth about Plug-in Hybrids, Made Interactive" that summarizes a January 2008 report from Oak Ridge National Laboratory and shows why plug-in vehicles in the U.S. will, on average, be just a little bit dirtier than gasoline HEVs. You read that right – dirtier, not cleaner! I first raised the issue in an August 2009 article titled PHEVs and EVs, Plugging Into a Lump of Coal, where I estimated that plug-in vehicles would be about 25% cleaner than HEVs, but the marginal cost...

John Petersen Since last week's article, Common Sense in Energy Storage Investing, was well-received by readers who've recently discovered this blog and want to better understand the energy storage sector, I've decided to continue with the theme and drill down deeper into some broad issues. Most of today's material is pretty basic stuff, but when the hype machine starts spinning a firm grasp on economic reality and investment fundamentals can be important to investors that want to avoid a boom and bust bubble like we had in corn ethanol. In the fall of 2008 I confessed to...

John Petersen On August 28th, the Office of the Inspector General of the U.S. Postal Service published the results of a feasibility study titled, "Electrification of Delivery Vehicles." While the feasibility study reaches a foregone conclusion and recommends the purchase of a 3,000 unit demonstration fleet, I was surprised by the high level of Federal subsidies the Inspector General thought necessary to bring EVs within Postal Service capital investment policies. I was even more surprised by the conclusion that the tipping point in the economic analysis was revenue from ancillary vehicle to grid, or V2G, services. The...

John Petersen While I jumped the gun last week and published my third quarter outlook for the energy storage and vehicle electrification sectors early, it's worthwhile to take a look back and see how my tracking list of companies performed over the last quarter and examine the past to see what the tea leaves in the bottom of the cup portend for the coming quarter. So without further delay I'll present my price performance table for the second quarter that ended on Friday. Q-2 was a dreadful quarter for Maxwell Technologies (MXWL) and ZBB Energy...

John Petersen For several weeks I've been writing about robust demand in Europe for a new class of HEVs that are usually referred to as "stop-start" or "micro hybrids." According to the EPA's website: "Stop/Start hybrids are not true hybrids since electricity from the battery is not used to propel the vehicle. However, the Stop/Start feature is an important, energy-saving building block used in hybrid vehicles. Stop/Start technology conserves energy by shutting off the gasoline engine when the vehicle is at rest, such as at a traffic light, and automatically re-starting it when the driver pushes...

by Debra Fiakas, CFA Most investors, if they have heard of Hydrogenics Corporation (HYGS: Nasdaq) at all, consider them a fuel cell producer. However, about two-thirds of the company’s revenue comes from the design and manufacture of hydrogen generation products based on water electrolysis technology - a somewhat unique, but valuable electrochemical technology that could make important contributions to the world’s future energy base. Electrolysis or the splitting of water molecules using an electric current produces hydrogen and oxygen - two elements that have market potential in a variety of industrial and power markets. It stands in...

John Petersen wrote a series of popular articles last week to introduce new investors to the battery sector, following the A123 IPO.  We've had a couple requests from readers who missed one part or another, so here is a quick index to the articles. Part I - Battery industry overview. Parrt II - Comparison of energy storage technologies and companies. Part III - Benchmarking Performance of battery stocks Part IV - Debunking misconceptions about electric vehicles and battery technology.

John Petersen Baron Rothschild, an 18th century British nobleman, is credited with saying, "Buy when there's blood in the streets, even if the blood is your own." Later this week I expect a blood in the streets buying opportunity in the stock of C&D Technologies (CHP) and intend to take advantage of it. It's unquestionably a contrarian investment, but one that could pay off handsomely. I want to thank Ben S, a regular reader, for bringing this opportunity to my attention in an e-mail last weekend. Most investors know that the addition of a company's stock...

John Petersen In recent years lithium-ion batteries have been portrayed as glamorous, sleek, sexy and hot – the stuff of adolescent fantasy and mid-life crisis. Reality is more like a surreal remake of the Dance of the Hours sequence in the Disney classic Fantasia where hippos in pink tutus gossip about overweight dancing elephants. Let's face it folks, there are no cheetahs in the battery ballet. While lithium-ion battery packs are smaller and lighter than their lead-acid counterparts, both types of batteries are ridiculously heavy substitutes for a fuel tank. The sad part is that whispers from hippos...

John Petersen We all love to whine and complain about oil prices because we buy gasoline regularly and that makes the price changes obvious. To solve this overwhelming problem, myopic visionaries with rose colored glasses propose a simple solution – convert personal transportation from vehicles powered by oil to vehicles powered by clean, free and renewable electricity from the wind and sun. Like most fairy tales, it can't happen in real life which means it won't. This is not a technology issue. It's a raw materials issue and electric vehicles cannot solve the problem. In the first...

*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...

Jim Lane HydroMan may do his hydrogen-shift thing via water, at will – but outside of the Marvel Cinematic Universe, we have some hydrogen issues. Psst! Like cutting out a fossil hydrogen dependency for many biofuels. But, new pathways ensure that the status hydroquo may not last for long. A numbers of readers responding to “Biofuels from a raging fireball” (on research work with the raging fireball, Pyrococchus furiosus, to make biofuels and renewable chemicals from hydrogen gas and CO2) raised the question, where is all the hydrogen going to...

John PetersenLast Friday I published "Battery Investing for Beginners" as an introductory piece for investors who don't know much about the energy storage sector but are interested in learning more because of the hugely successful initial public offering by A123 Systems (AONE). Since the article was well received and there seems to be a good deal of reader interest, I've decided to continue the theme with a series of articles where I'll try to build a contextual framework for the industry and show where various types of energy storage devices and their manufacturers fit into that framework. Since I...

John Petersen I'm a cynic and a heretic when it comes to plug-in vehicle schemes because most defy the laws of economic gravity and violate a cardinal rule that Ford engineers developed for the EcoStar light delivery vehicle program in the early '90s: – The unloaded weight of a plug-in vehicle should never exceed 70% of its loaded weight. Investors who pay attention to this simple rule can easily distinguish between pipe-dream vehicle electrification schemes that are nothing more than feel-good eco-bling and realistic vehicle electrification projects that make economic sense. For the last...

Tom Konrad CFA Electric Storage Battery Company advertisement for Exide batteries in the journal Horseless Age, January 15, 1918 I sold my position in Exide Technologies (NASD:XIDE) on April 25th after the company was forced to shut down its Vernon secondary lead recycling facility by the California Department of Toxic Substances (DTSC.)  In addition to the known arsenic furnace emissions, the DTSC cited the facility’s underground storm water system as not being in compliance with CA requirements. When I last wrote about Exide, I felt that the problems at the Vernon facility were not...
