Energy Storage

In mid-February President Obama signed the American Recovery and Reinvestment Act of 2009 (ARRA), a massive spending bill that spawned gigabytes of analysis and comment from bloggers like me. Unlike many, I've tried to stay politically agnostic and focus solely on the economic impact of ARRA on companies that manufacture batteries and other energy storage devices. From that limited perspective, everything is wonderful! The principal energy storage appropriations included in the ARRA were: $4,500,000,000 for grants for “Electricity Delivery and Energy Reliability” including activities to modernize the electric grid, include demand response equipment, enhance security...

Tom Konrad CFA On June 1st, in the lead up to Exide Technologies’ (NASD:XIDE) first quarter earnings announcement, I made one of my better calls so far this year.  I wrote that the Exide stock was in the “bargain basement” and “ready to pop.” That day, XIDE traded in a range of $2.25 to $2.36, within spitting distance of its 52 week low of $2.22.  Four months later, the stock is up 45% at $3.25, despite two earnings misses in the meantime. My Mistake Unfortunately, I missed out on a good chunk of that gain.   A week...

John Petersen Last week I stumbled across a link that led to a 2010 report from the National Research Council titled "Hidden Costs of Energy, Unpriced Consequences of Energy Production and Use." This free 506-page book takes a life-cycle approach – from fuel extraction to energy production, distribution, and use to disposal of waste products – and attempts to quantify the health, climate and other unpriced damages that arise from the use of various energy sources for electricity, transportation and heat. After studying the NRC's discussion of the unpriced health effects, other nonclimate damages and greenhouse gas...

by Debra Fiakas CFA In my last post Paper Power I outlined the attempt to develop a battery using carbon nanotubes and paper.   The materials seemed a bit unbelievable and it sent me into the history books to look at the battery.  In the mid-1700s Ben Franklin may have been the one who first coined the term battery to describe the capacitors had strung together for his experiments.  We all know about the scientist, turned politician.  What is less well known is that the ancients may have also attempted a battery-like instrument now called the “Baghdad Battery.” ...

John Petersen I was recently invited to prepare a memorandum on the battery industry for the electric mobility working group of the World Energy Council, a global thought leadership forum established in 1923 that includes 93 national committees representing over 3,000 member organizations including governments, businesses and research institutions. Since my memorandum integrated several themes from this blog and tied them all together, I've decided to publish a lightly edited version for readers. To set the stage for the substantive discussion that follows, I’ll start with an 1883 quote from Thomas Edison: “The storage battery is one...

10.08.09 ACPW John Petersen This morning I awoke to a comment from Seeking Alpha contributor Michael Eisenberg who asked me to lay out my core thesis on why Active Power, Inc. (ACPW) merits attention from investors who are interested in the energy storage sector. While Altenergystocks and Seeking Alpha don't generally like to publish articles about companies that trade for under a dollar, I believe Active Power merits an exception to the general policies. As regular readers know, I've been a small company securities lawyer for almost...

In June, I wrote how intermittent power sources such as photovoltaics and wind would have to compete with baseload technologies such as IGCC "Clean Coal" and nuclear for capacity on the grid.  The key problem is that neither baseload technologies nor intermittent technologies are able to match themselves to the fluctuations of demand.  This creates a need for technologies which can fill the varying gaps between supply from these sources, and normal energy use.  From the comments, it seems like I was not completely clear how intermittent and baseload power cause problems for each other, so I will start...

John Petersen After the market closed on Monday, Exide Technologies (XIDE) released surprisingly poor second quarter results, a $3.6 million loss that included a $5.7 million charge for several years of reporting irregularities at a small Portuguese recycling subsidiary. The market's reaction was absolutely savage as the stock collapsed from Monday's close of $4.48 to Friday's close of $3.01. In my view, the reaction was unjustified and has set up a tremendous buying opportunity for investors who are willing to look beyond the headlines and focus on core business fundamentals. To put things in perspective, Exide's...

John Petersen On November 6th I published Lesson #1 in this series, which provided a quick side-by-side comparison of Ener1 (HEV) and Exide Technologies (XIDE). Yesterday two more companies that I track, A123 Systems (AONE) and Enersys (ENS), reported results for the September quarter. The quick summary is that Enersys handily beat street estimates while the bleeding at A123 continued unabated. To follow up with the format I introduced last week, the first graph is a simple market performance comparison of the two companies over the last year. The second graph comes from my...

John Petersen One of the most seductive and dangerous stock market myths is the immensely popular but demonstrably false notion that the rapid cost reductions and performance gains we enjoyed during the information and communications technology revolution will be repeated in the age of cleantech. The persistence of the mythology is astonishing when you consider that the entire history of alternative energy proves that cost reductions and performance gains are extraordinary events, rather than common occurrences. Investors who buy into economies of scale mythology without carefully considering the fundamental differences are in for a world of disillusionment and...

John Petersen One of the most fervently debated and poorly understood topics in energy storage is the subject of battery recycling. What percentage of the raw materials that go into a battery can be economically recovered from used batteries with existing recycling technology and infrastructure? While the details are quite complex, this article will offer a high-level overview of the economics of battery recycling for energy storage investors. Lead-acid batteries are the most recycled products in the world. The process is both straightforward and cost-effective. When batteries arrive at the recycling plant, they're put through a shredder...

John Petersen Industrial subsidies have been an important feature of the American economic landscape since the late 19th century for one simple reason – they work. After the steam locomotive proved its ability to quickly and cheaply move people and cargo long distances, the government launched a massive effort to span the country with steel rails and bring the benefits of a rapid, safe and reliable national transportation system to all its citizens. After electric lighting proved its merit, the rush was on to build a national infrastructure and bring the benefits to all. After the internal combustion...

Active Power Inc (ACPW) announced the shipment of its first CleanSource® XR evaluation unit to one of the largest producers of electricity in the United States. The CleanSource XR unit will be tested under a variety of conditions for both backup power and load-shifting applications. CleanSource XR stores energy in the form of heat and compressed air. When power is needed, the compressed air is routed through a thermal storage unit to acquire heat energy. The heated air spins a simple turbine-alternator to produce 5 to 85 kW of electric power for up to several hours. Unlike commonly...

John Petersen I've been writing about micro-hybrid vehicles and stop-start idle elimination since May 2009. It's a cheap and simple fuel efficiency innovation that turns the engine off while a car is stopped at a light and automatically restarts the engine when you take your foot off the brake. It's not gee-whiz sexy, but it can boost fuel economy by 5% to 15% in city driving and dramatically improve urban air quality by reducing idling. What could be more sensible? When I first wrote about stop-start in "Why Advanced Lead-acid Batteries Will Dominate the HEV Markets," the...

John Petersen For the last two years I've been paying increasingly close attention to trailblazing work by Norfolk Southern (NSC) in the field of battery-powered locomotives. My interest was piqued in June of 2010 when Norfolk Southern hired Axion Power International (AXPW.OB) to develop a battery management system that would allow rail locomotives to run on battery power and recharge their batteries through regenerative braking. I believed the decision was positive news for Axion because nobody hires a battery manufacturer to design a BMS for somebody else's product. My enthusiasm was tempered, however, by knowing that an earlier...
