Yes sir, we got grant money: Rounding out the four largest grants was $7.2 million to develop low cost, megawatt-rated batteries capable of backing up and smoothing out the intermittent energy supply from wind farms and other renewable sources. Today, such power-grid-scale batteries are prohibitively expensive for most renewable energy applications. EaglePicher Technologies of Joplin, Missouri, and the Pacific Northwest National Laboratory in Richland, Washington, will use the funds to develop a sodium beta alumina battery that will cost no more than $200 per kilowatt hour of capacity, compared with about $500 today. http://www.newscientist.com/article/mg20427355.300-us-bets-150m-on-renewable-energy.html
