New batteries coming for solar powered homes

solar-rooftopsWant a Solar-Powered Home? Here’s a New Battery That Won’t Ignite
As solar panels and wind turbines spread worldwide, they’ll need batteries to store power for times when they don’t produce it. Harvard debuts a promising prototype. By Wendy Koch, National Geographic  SEPTEMBER 24, 2015 If you dream of an off-grid house powered by the sun, plan on a battery to store energy for cloudy days—ideally, one that won’t catch fire. Harvard researchers might have just the fix.

 In the race to build the battery of the future, they’re unveiling a unique option. They say their flow battery is the first made with cheap, non-toxic, non-corrosive, non-flammable, high-performance materials.

“It is a huge step forward. It opens this up for anyone to use,” says Michael Aziz,  Harvard University engineering professor and co-author of a study published Thursday in the journal Science. Because the battery is safe and non-corrosive, he says, it’s well suited for both businesses and homes, adding: “This is chemistry I’d be happy to put in my basement.”………http://news.nationalgeographic.com/energy/2015/09/150924-nonflammable-battery-could-charge-solar-homes/
