Last Friday I received my copy of the presentations from September's European Lead Battery Conference in Istanbul. Most of the presentations were written for a technically astute audience and don't offer much in the way of concrete guidance for investors, but an overview presentation from Ricardo PLC, a global leader in engineering solutions for low carbon, fuel-efficient transportation, included three slides that merit serious investor consideration and show why I'm convinced cheap will beat cool for the next decade of vehicle electrification. I've posted a copy of the Ricardo presentation here.
The first slide is a simple timeline that answers the eternal question "When are the technological wonders we read about on a daily basis likely to become profitable business reality?"
Lead-acid batteries have been the dominant energy storage technology for the last century and the global manufacturing footprint is immense. As vehicle electrification becomes more commonplace and energy storage requirements increase, leading lead-acid battery manufacturers including Johnson Controls (JCI), Exide Technologies (XIDE) and Enersys (ENS) are seeing a pronounced shift in demand patterns. Users who once bought inexpensive first-generation flooded batteries are now buying premium second-generation AGM batteries. Concurrently, lead-acid technology innovators like Axion Power International (AXPW.OB) are finishing development and testing of third-generation devices that will bring the power and cycle-life of lead-acid batteries up to a level that's comparable with NiMH batteries at a reasonable cost. The bottom line for investors is that lead-acid battery technology is rapidly improving and barring a seismic technological shift, manufacturers can only get more profitable over the next decade as global demand for cost-effective mass-market energy storage products surges.
Nickel Metal Hydride, or NiMH, has been the battery chemistry of choice for HEVs since Toyota (TM) introduced the Prius in 1997. Over the last decade HEVs have earned an enviable reputation for efficiency and reliability. Unfortunately, the "M" in NiMH batteries is the rare earth metal lanthanum, which is only produced in small quantities and primarily mined in China. While material supply constraints have not limited NiMH battery production in the past, China has recently announced plans to limit rare earth metal exports in the future. Therefore looming supply constraints will limit the scalability of current HEV technology and most observers believe future HEVs will have to accommodate a lateral substitution of advanced lead-acid batteries and accept a slight weight penalty, or accommodate an upgrade substitution of lithium-ion batteries and suffer a substantial cost penalty.
For several years, dreamers, politicians and environmental activists have shamelessly portrayed lithium-ion batteries as a silver bullet solution to the planet's energy storage needs. From Ricardo's perspective, however, large-format lithium-ion batteries are just beginning to emerge from the prototype stage and enter the early commercialization and demonstration stage. Nissan (NSANY.PK) and General Motors (GM) have recently introduced the Leaf and the Volt and publicized ambitious plans to expand EV production. Those plans, however, will depend on mass-market acceptance of expensive products that haven't been adequately tested under real world conditions by people who just want reliable transportation. I've always believed the ramp rate for plug-in vehicles would be slower than the historical ramp rate for HEVs because users will inevitably have problems with dead batteries, range limitations and other performance issues. As the problem stories spread through the grapevine, the only possible outcome is reduced demand. Ricardo believes it will take at least six years before EVs begin to make the transition from the bleeding edge of early commercialization and demonstration to the leading edge of mass production. I think ten years is more likely....MORE
