The EIA Offers Another Reality Check For Energy Storage Investors
The core data for this article was taken from Table 57, which forecasts light-duty vehicle sales by drive technology type for the years 2007 through 2035. To simplify the presentation I've consolidated all data for passenger cars and light trucks into five broad classes and then prepared a simple stacked column graph to present a market forecast snapshot at five-year intervals.
What are not clear in the 2010 statistics are the changes from 2009. A detailed discussion of the individual changes would be too detailed for a blog, however the general overview is that the EIA increased market penetration for ethanol-flex fuel vehicles by almost 100%, reduced short- to medium-term penetration rates for plug-in vehicles by almost 50% and reduced long-term penetration rates for HEVs by a like amount. Apparently the EIA believes that budgets matter to most consumers and high-end electric assist vehicles will be priced out of the market for the foreseeable future. For those that are interested in tracking the specific changes, the archived workbook for the Annual Energy Outlook 2009 is available here.
Many people have invested in lithium-ion battery companies based on the widely publicized promise that plug-in hybrid electric vehicles and pure electric vehicles, which have recently been christened grid enabled vehicles, or GEVs, by the Electrification Coalition, would be the rising superstars of the automotive markets over the next 25 years. As of two weeks ago the EIA expected GEVs to represent 0.86% of the U.S. market in 2020 and a whopping 2.63% by 2035. Even this cynic was shocked. To drill down a bit further and attempt to translate the EIA's automotive market forecasts into revenue expectations for battery manufacturers I assumed:
- Revenue of $250 per vehicle for advanced lead-acid starter batteries;
- Revenue of $1,000 per kWh for automotive grade lithium-ion batteries;
- A 1.5 kWh battery requirement for an HEV;
- A 4 kWh battery requirement for a PHEV-10;
- A 16 kWh battery requirement for a PHEV-40; and
- A 24 kWh battery requirement for a pure electric vehicle.
|GEV battery sales||$2,012||$2,548||$2,951||$3,750||$4,662||$5,099|
|HEV battery sales||$372||$967||$1,281||$1,595||$1,961||$2,215|
|Lead-acid battery sales||$2,530||$3,904||$3,852||$3,864||$4,008||$4,189|
While there are many EV advocates who will strenuously argue that a battery cost estimate of $1,000 per kWh for lithium-ion batteries is way too high, it's well within the price range cited by the National Research Council in its recent report titled "Transitions to Alternative Transportation Technologies – Plug-in Hybrid Electric Vehicles." While future lithium-ion battery prices may in fact decline significantly, I've always wondered how rapidly falling battery prices will be a good thing for the shareholders of battery manufacturing companies that presumably would rather make money from selling a reasonably priced product than struggle with the problems of selling a commodity product on paper thin margins. I guess some sophisticated business concepts are above my pay grade. In Joseph Heller's classic novel Catch 22, Milo Minderbinder planned to buy eggs for a dime, sell them for a nickel and make it up on volume. That's not a business plan I want to buy into.
Two of the three largest lead-acid battery manufacturers in the world are publicly held. Johnson Controls (JCI) is a diversified auto-parts manufacturer that derives roughly $3.9 billion per year, or roughly 16% of its total revenue, from the lead-acid battery business. Exide Technologies (XIDE) is a pure play lead-acid battery manufacturer with global revenues of roughly $2.5 billion. The industry newcomer is Axion Power International (AXPW.OB), a developer of advanced lead-carbon batteries for the micro and mild hybrid applications that entered into a global supply relationship with Exide in April, was selected with Exide to receive a $34.3 million ARRA battery manufacturing grant in August, and recently completed a $26 million private equity placement lead by Special Situation Funds, Manatuck Hill Partners and Narragansett Strategic Master Fund.
The leading publicly held companies that operate in the U.S. and plan to manufacture lithium-ion batteries for automotive applications are Johnson Controls (JCI), A123 Systems (AONE), Ener1 (HEV), Valence Technologies (VLNC) and Altair Nanotechnologies (ALTI).

I've always believed that successful investing requires a growth industry, a well-managed company, a good product, reasonable profit margins and an objectively low entry price based on current earnings or future potential. If the EIA forecast is even close, the market seriously underestimates the future potential of the lead acid group while fully valuing, if not overvaluing, the future potential of the lithium-ion group. The lead acid battery manufacturers also trade at far lower multiples of sales and book value than the lithium-ion manufacturers. Under the circumstances I think that substantial short-term appreciation is far more likely in low-priced stocks like Exide, Axion and Altair than it is in high-priced stocks like JCI, A123 and Ener1.
I got nothing but flack and disrespect in November of 2008 when I had the gall to suggest that cheap would beat cool. As my year-end review will show next week, the last 12 months have proven me right. The good news is that much of the valuation disparity that existed last year is still present and some very solid companies remain available at attractive prices.
