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 In his 2006 State of the Union Address, President George W. Bush said: "Keeping America competitive requires affordable energy. And here we have a serious problem: America is addicted to oil, which is often imported from unstable parts of the world. The best way to break this addiction is through technology." What a crock of balderdash! If you compare US fuel prices with those in other industrialized countries, gasoline is a screaming bargain and the same can be said for electricity. It's not the energy we use that's a problem. The problem is the...

Energy Conversion Devices Inc (ENER) opened up trading this morning with a gap down to the $33 level. For the last hour it has been steadily rising up from this point. As I said in my earlier post, I have been looking for a good entry point in this company and feel that the near term support of $33 is an ideal area to place an order. The stock has been on a run for several months and it is always hard to take a new position in a stock that has already seen dramatic increases...

Since November of last year, I’ve argued that cheap will beat cool when it comes to the commercialization of battery chemistries. As details on the design and construction of the Chevy Volt battery pack emerge and are publicized on sites like Green Car Congress and Popular Science, it’s clear that cheap Li-ion chemistry has already beaten cool Li-ion chemistry and many of the concerns I’ve expressed about using Li-ion batteries in cars have been considered and resolved by thoughtful automotive design engineers. It bodes well for the introduction of PHEVs as long as the tax incentives remain in place,...

by Debra Fiakas CFA Near the end of February 2014, Highpower International (HPJ:  Nasdaq) announced its first order for large-format lithium ion batteries to use in electric vehicles. Its customer, Huizhou Yipeng Energy Technology will be integrating the batteries into buses destined for the sales outlets of China-based manufacturers. The boost in sales for Highpower is likely to be meaningful.  Management estimates each bus will use as many as 288 of the company’s 20-ampere-hour battery.  Guidance for annual sales from Huizhou Yipeng alone is in a range of $4 million to $5 million.  In the most...

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...

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...

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...
