Batteries - Some Demand Side Movement

Rod Janssen has recently re-posted an article by Chris Mooney in the Washington Post on recent developments in the US large battery market. The main thrust is an increase in demand side pull, mainly for peak lopping but also for back-up, coupled with a willingness on the supply side to provide such facilities. Tesla's power packs are to the fore. Such activity is good news, not really for the direct impact it will have, but because it adds to the innovation stimulus to seek more efficient and robust batteries and/or fuel cells.
