Energy Storage

John Petersen I'm going to apologize up front for revisiting a topic that inevitably draws furious comment from readers who just don't get it, or who refuse to get it. I understand that it's painful to learn that politicians, environmental advocates and the mainstream media have been lying about critical issues, but that doesn't make exposing the lies less important. So I'm going to endure the slings and arrows of the eco-religious one more time and use a new example to show that plug-in vehicles are a luxury no nation can afford. Ener1 (HEV) is a pure-play...

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...

SatCon Technology Corporation (SATC) announced that it has received a follow-on purchase order for a second 2200 kVA Rotary Uninterruptible Power Supply (RUPS) on a government contract valued in excess of $1.1 million. SatCon's StarSine(TM) Rotary UPS is designed to provide both high quality electrical power during normal operation, as well as prevent any interruption of electricity to critical manufacturing processes, telecommunication centers, data centers, and healthcare facilities in the event of power grid failures such as black-outs and brown-outs. The RUPS is connected directly to SatCon's patented flywheel for short duration power disturbances and is integrated...

Comparison of Energy Storage Technologies from Solar 2009 Tom Konrad, Ph.D. A reader and  CEO of a fuel cell startup sent me an email asking for a copy of my presentation comparing energy storage technologies which I referred to in last months article on Renewable Energy integration.  Since other readers may be interested as well, here it is: Economic Comparison of Electricity Storage Technologies (Power Point Show, 721 kb) Here is also the spreadsheet where I gathered most of the data for the graphs. (Excel spreadsheet 74 kb) Visual Comparisons These following graphs can also be found in the...

ZAP (ZAPZ) is at the Consumer Electronics Show in Las Vegas to unveil its new battery system to one of the world's largest events for the electronics industry. A pioneer in electric cars, scooters, bicycles and other advanced transportation technologies, ZAP is establishing an energy division for the advanced energy technologies it has been developing for cars and packaging it for the electronics industry.

John Petersen Last week I appeared as a luncheon speaker at EESAT 2009, a biennial international technical conference sponsored by the DOE, Sandia National Laboratories and the Electricity Storage Association that focuses on storage technologies for utility applications. The conference included dozens of high-level technical presentations from storage technology developers and was far and away the best-organized event I've ever attended. The only notable absence was a large contingent of buyers, which left some participants wondering whether they were preaching to the choir. Nevertheless, I was encouraged by rapid growth in the number and size of utility-scale demonstration...

John Petersen In late June I wrote a forward looking article that identified several companies in my energy storage and vehicle electrification group that I expected to perform well or perform poorly during the third quarter. Since short-term market changes are notoriously hard to predict, it’s worthwhile to look back and see where I got things right and where I got them wrong. So I’ll start today with a quick summary table and assess the relative accuracy of my Q3 calls, and then turn my attention to Q4, which is shaping up as a time of bright opportunity...

Debra Fiakas Alliance photo via BigStock  Exide Technologies (XIDE:  Nasdaq) is one of the largest transportation and industrial battery suppliers in the U.S., vying for market share with Johnson Controls (JCI:  NYSE) and EnerSys (ENS:  NYSE) among others.  Batteries are a competitive business, even as the automotive sector has attempted a recovery from the 2008 free fall in new car sales.  Electric vehicle and renewable energy storage applications have helped expand addressable market.  However, for a conventional battery producer capturing a share of these...

Arotech Corporation (ARTX) announced today that its Battery and Power Systems Division has received a pilot order for its new 4th generation man portable Zinc Air battery packs from the US Air Force. Developed and manufactured by its Electric Fuel Battery Corporation subsidiary, Arotech's new battery pack is a 12 or 24 Volt battery with a total capacity of over 400Wh and Battery Energy Density of approximately 300Wh/kg. The new battery pack is optimized for use in vests, as man portable tactical radios are typically vest-worn in holsters. The pack is also designed for use in rucksacks. ...

John Petersen Over the last couple of years, the mainstream media has been awash in reports of how automakers are lining up to build fleets of PHEVs and EVs using lithium-ion batteries as a principal power source. I've consistently argued that investing in objectively expensive lithium-ion battery company shares on the basis of testing decisions was dangerous. The reason for my caution is simple, a decision to test a new concept is very different from a decision to commercialize a proven concept and failures in the preliminary testing stages are far more common than successes. In...

John Petersen Last week Debra Fiakas of Crystal Equity Research published an article titled "No Battery Producer Left Behind" that was based on old information about the relationship between Exide Technologies (XIDE) and Axion Power International (AXPW) and reached several erroneous conclusions. Since I'm a former Axion director, the stock is my biggest holding and I follow the company like a hawk, Tom Konrad asked me to clarify the record and present a high level overview of Axion's business history, stock market dynamics and technical accomplishments over the last four years. Since Tom's request is a...

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,...

On April 1st CNET News published a story about a previously secret technology that Google (GOOG) has patented and implemented system-wide. The technology, which Ben Jai of Google reportedly described as their "Manhattan Project," builds a 12-volt battery into each server to provide backup power. The point that fascinates me is Google's choice of small format valve regulated lead-acid batteries to keep its servers running. When an ultra-sophisticated company like Google picks cheap over cool for a mission critical function, I think it speaks volumes about the future direction of the energy storage industry. Stephen Shankland of...

John Petersen With only a couple trading days left in 2009, this is as good a time as any for a performance review. The predictions I made at this time last year were pretty solid with an 80% accuracy rate on price direction. For the year, a $1,000 investment in each of my green star companies would have yielded a portfolio appreciation of 67%, which handily beat the broader market indices. That being said, my star and caution ratings were a good deal less prescient because I seriously underestimated the potential of both Maxwell Technologies (MXWL) and Active...

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...

Hydrogenics Corp (HYGS) announced that the company has supplied an onsite electrolysis-based HySTAT-A Hydrogen Plant to OAO NSCHK, a state-owned utility in Novorsibirsk, Russia. The high-purity hydrogen produced by the 240Nm3/hr hydrogen generator will be used in the chemical processes used in this nuclear power plant. Installation and commissioning is scheduled for Spring, 2006.
