In August of last year I wrote an article titled " Grid-based Energy Storage: Birth of a Giant ." Over the last 12 months I've written a series of follow-on articles that discuss the principal classes of manufactured energy storage devices and the companies that are making or planning to make products for smart grid energy storage applications. My entire archive of articles on the energy storage sector is available here . One of the biggest problems I've encountered over the last year has been a dearth of third party data that can help investors understand the breadth and depth of the opportunity, and sift through the frequently contradictory claims of energy storage device manufacturers that plan to target the smart grid as a principal market. Since energy storage investors can be an opinionated lot, most of my articles have lengthy comment streams that are often more interesting than the articles themselves. Two weeks ago I ran across a story on greentechgrid that said NanoMarkets , a leading market research firm from Glenn Allen, Virginia, was predicting that the global market for storage batteries and ultracapacitors on the smart grid would grow to $8.3 billion by 2016 from its current level of $326 million. Since the market size and growth rates were very impressive and I track many of the companies identified in the greentechgrid story, I contacted NanoMarkets to see if they would give me a complimentary copy of their report. A little over a week ago I received a copy of NanoMarkets 102 page report titled " Batteries and Ultra-Capacitors for the Smart Power Grid: Market Opportunities 2009-2016 ." I've been like a kid in a candy store ever since. While the $2,995 report is a little pricey for individuals, it's a must read for institutions and large investors that are analyzing opportunities in the energy storage sector. It's also a wonderful planning tool for companies that are developing go to market strategies for manufactured energy storage devices. Individuals who want to better understand how the smart-grid market is likely to develop and grow over the next several years can gain important insight from a free June 2009 NanoMarkets white paper titled " Plug In to Materials Trends for Smart Grid Applications ." NanoMarkets has agreed to offer a $500 discount on the full report to my readers who contact Robert Nolan (rob@nanomarkets.net) and mention this article. Unlike forecasts from storage device manufacturers and stock market analysts who tend to focus on how a particular product, technology or company might fit in an emerging market, NanoMarkets approached the issue of smart grid storage from the end-user's perspective; meaning that they identified the customer's needs first and then focused on the companies that had cost-effective solutions for those needs. The principal near-term applications identified by NanoMarkets are: Load leveling and power quality systems to protect commercial and industrial users from brief power interruptions that cost an estimated $75 to $200 billion per year in lost time, lost commerce and damage to equipment; Peak shaving systems to help commercial and industrial users manage their electricity costs under variable utility tariffs and help utilities manage generating assets to minimize waste; Transmission and distribution support systems to help utilities reduce grid congestion, defer upgrades and minimize waste; and Renewables integration systems to help power producers, utilities and end users cope with the inherent variability of wind and solar power and better match peak wind and solar output with peak demand. In evaluating the likely development path for energy storage devices on the smart grid, NanoMarkets considered a variety of competing technologies including pumped hydro, compressed air, flywheels, chemical storage batteries, ultracapacitors and superconducting magnets. They ultimately concluded that: Pumped hydro and compressed air had limited growth potential because of geographical and geologic constraints; Because of their cost and complexity, flywheels and superconducting magnets were not likely to be widely used beyond niche applications; and Absent a revolutionary breakthrough in cycle life and cost, lithium-ion batteries will have limited value in the large-scale grid storage market. From my perspective one of the most refreshing aspects of the NanoMarkets report was their belief that storage systems for the smart grid will be chosen based on fundamental cost-benefit analysis. Equally important was their conclusion that emerging technologies would increase the overall demand for storage and result in rapidly increasing revenue for all product classes. So instead of facing a situation where an emerging technology takes sales away from an established technology, each class of technology can expect rapid sustained growth over the entire forecast period. When the forecasts for individual product classes are combined, it becomes clear that the overall market will reach explosive growth rates by 2016. The following graph provides a summary overview of NanoMarkets forecast for each of the principal battery classes over the next eight years. I can't begin to do the NanoMarkets report justice in the limited confines of a financial blog. They thoroughly discuss the development path for each of the principal smart grid markets; carefully review each of the leading developers of energy storage devices for the smart grid; and then break their sales forecasts down by specific applications and geography. If NanoMarkets' forecast is even close to being right, the next decade will be a period of explosive growth for: Sodium battery manufacturers like NGK Insulators ( NGKIF.PK ) and General Electric ( GE ) that can look forward to $1.3 billion in annual revenue growth for their sector over the next eight years; Supercapacitor manufacturers like Maxwell Technologies ( MXWL ) that can look forward to $1 billion in annual revenue growth for their sector over the next eight years; Lead-acid battery manufacturers like Enersys ( ENS ), Exide ( XIDE ) and C&D Technologies ( CHP ) that can look forward to $2.4 billion in annual revenue growth for their sector over the next eight years;; Lead-carbon battery manufacturers like Furukawa Battery (FBB.F), Axion Power ( AXPW.OB ) and Firefly that can look forward to $2.75 billion in annual revenue growth for their sector over the next eight years; and Flow battery manufacturers like ZBB Energy ( ZBB ) that can look forward to $500 million in annual revenue growth for their sector over the next eight years; For energy storage investors who truly want to understand where the smart grid energy storage device market is today and how it is likely to develop through 2016, the NanoMarkets report could well prove to be the soundest investment of all.
