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 On June 8th Switzerland's ABB Group Ltd. (ABB) announced an agreement to buy UK-based Chloride Group PLC (CHLD.L) for £860 million in cash, or approximately $1.26 billion. This stunning purchase provides the best evidence yet that lead-acid battery manufacturers including Enersys (ENS), Exide Technologies (XIDE) and C&D Technologies (CHP) are woefully undervalued and offer outstanding opportunity for patient and risk tolerant investors. ABB is the gold standard in the secure and efficient generation, transmission, distribution and use of electricity in utility, industrial and commercial applications. Its portfolio ranges from light switches to robots, and from...

John Petersen It's been a very good week for companies in the lead-acid battery sector and from all indications the fun is just beginning. Unlike most market sectors, the principal players in the lead-acid group report on a fiscal year basis instead of a calendar year basis. Enersys (ENS) and Exide Technologies (XIDE) both use fiscal years that end March 31st, and C&D Technologies (CHP) uses a fiscal year that ends January 31st. That makes the first two weeks of June a busy time as Enersys and Exide report annual results and C&D reports first quarter results. ...

John Petersen Last week the American Chemical Society published a white paper in Environmental Science & Technology from a team of researchers at Tsinghua University, Beijing, and the Argonne National Laboratory Center for Transportation Research titled "Environmental Implication of Electric Vehicles in China." This white paper concludes that: Implementing electric vehicles in China will increase national CO2, SO2 and NOX emissions; and Gasoline HEVs are more environmentally friendly, more commercially mature, and less cost-intensive. The following graph comes from page 4 of the white paper and compares the relative fleet wide CO2 emissions for gasoline ICEs,...

John Petersen I've written several articles over the last year that explain why idle elimination is a crucial first step in the global effort to increase fuel efficiency and curb CO2 emissions. For readers who are new to my blog, or confused by a torrent of news stories and analysts reports that wax poetic on the expected benefits, costs and challenges of gee-whiz vehicles that are "coming soon to a showroom near you," altenergymag.com describes stop-start systems, or micro-hybrids, as follows: "These are conventional vehicles powered either by gasoline or diesel engines in which the 12-volt starter...

John Petersen Since I discussed dilution risks in emerging energy storage companies last week, today I'm going to shift gears and offer an overview of the opportunities that have developed in larger pure-play energy storage companies since last September. The following graph tracks the 18-month composite performance of the five categories I defined in Battery Investing for Beginners, Part II and shows how they stacked up against the Dow Jones Average. To understand what's happened in the storage sector over the last 18 months it's helpful to remember a few key dates. First, we had...

John Petersen The greatest truth in micro-cap corporate finance is that small companies have a lot in common with small children in third world countries – they rarely die of starvation but they frequently die of dysentery. In hard times, small companies that need additional capital can usually find the cash if their management has enough humility to accept the price the new financiers are willing to pay. The problems can quickly become life threatening, however, if management fails to adjust spending to accommodate business conditions or rejects available financing because the terms seem predatory. My advice to...

John Petersen For the last few days the green transportation press has been beside itself with breaking news that the battery pack for the Nissan Leaf costs a staggeringly cheap $375 per kWh. They point to the Times of London as their source, but fail to note that the cost figure was buried in a throwaway sentence in the seventeenth paragraph of an April 4th story about a British executive who'd been transferred to Nissan's headquarters in Tokyo to run their green cars program. This isn't proof folks, it's hearsay elevated to nonsense that belongs in...

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 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 On April 8th the Electrification Coalition, a recently formed industrial lobby comprised of top-level executives from Cisco Systems (CSCO), Aerovironment (AVAV), NRG Energy (NRG), Rockwood Holdings (ROC), Nissan Motors (NSANY.PK), FedEx (FDX), A123 Systems (AONE) and a gaggle of private companies released a slick but wholly unenlightening white paper titled, "Economic Impact of the Electrification Roadmap." I haven't seen so many finely sculpted curves and unspoken assumptions since the tax shelter forecasts of the early-80s. The only clear message is that electric drive will be little more than a footnote in automotive history unless the powers...

John Petersen On April 1st the National Highway Traffic Safety Administration and the Environmental Protection Agency announced a joint final rule establishing fuel economy standards for all light duty vehicles sold in the United States. In my last article, I focused on the overall fuel efficiency improvements the new CAFE regulations will require. After spending a couple days reading and digesting the Final Rule Release, which runs to 1,469 pages, I've concluded that my initial optimism over the future of start-stop technology was understated. The Final Rule Release begins with several hundred pages of introductory...

John Petersen On April 1st the National Highway Traffic Safety Administration (NHTSA) and the Environmental Protection Agency (EPA) announced a joint final rule establishing fuel economy standards for all light duty vehicles sold in the United States. Since the existing standards don't apply to light trucks, I used vehicle sales forecasts from the Energy Information Administration's "Annual Energy Outlook 2010" to estimate a current baseline fuel economy of 19.6 mpg. The new rules will be phased in over a five-year period beginning with the 2012 Model Year and are certain to drive rapid evolution in the auto industry....

John Petersen The first quarter was unkind to publicly traded companies in the energy storage sector, which saw their stock prices fall by an average of 16.22% over the last three months. While the shares of Enersys (ENS) and C&D Technologies (CHP) posted gains of 12.8% and 3.2% respectively, all of the others in my universe of 17 pure play energy storage companies traded down. The following table summarizes first quarter performance and provides some important valuation metrics. The following table summarizes the portfolio performance a hypothetical investor would have realized over the last three...

John Petersen Albert Einstein once said, "If you can't explain it simply, you don't understand it well enough." So when the editor of Batteries International asked if I could present my analysis of plug-in vehicles in two pages and prove my numbers in a way that any open-minded adult could follow, understand and verify with an Internet search engine, I jumped at the challenge. The article was published yesterday in their Winter Edition. Since the numbers have profound implications for the energy storage sector and an expected flurry of ill-conceived electric vehicle projects like the planned Tesla Motors...

John Petersen Since I'm frequently chastised for holding old fashioned views when it comes to vehicle electrification, I'll start this article by quoting one of the oldest known versions of a common English proverb, "A byrd in hand - is worth ten flye at large." While this theme is not always clear in my writing, it's never far from my thoughts. In fact it's the foundation of my conviction that manufacturers of cheap energy storage products are better investments than developers of cool energy storage products and batteries are great at minimizing waste but miserable at replacing fuel...
