Harvard team develops a new organic-based flow battery using quinone. It can be found in plants or synthesized from oil, and costs about $27 per kilowatt hour of storage capacity, compared with $700 for conventional metal batteries.
Between this and graphene it appears as though we are taking some significant leaps in sustainable battery storage. The question is, when will these technologies become the standard? What do you think it will take for us to truly push away from non-sustainable energy?
It's still incredibly early in the work. They don't even have a prototype yet. It will be a few years in research still. But you are right it is very promising. Our main problem is energy storage. Once we can bring down that cost, it will solve a great many issues.
Hopefully graphene will be able to help with that. It seems to be very promising for energy storage. Though it would possibly flood devices so there is that issue. Same deal, more research is necessary, http://m.youtube.com/watch?v=NPResi9p5uU this video explains the benefits nicely.
