ent aqueous flow battery utilizing quinone couples has been developed jointly by the Gordon, Aspuru-Guzik and Aziz (SEAS) groups, displaying a remarkable >99% storage capacity retention per cycle. No precious metal electrocatalysts are necessary. The [Harvard Gazette](http://news.harvard.edu/gazette/story/2014/01/renewable-energy-breakthrough/) reports that the quinone identified for the study, 9,10-anthraquinone-2,7-disulfonic acid, is similar to one in rhubarb. On January 14th, Professors Gordon and Aziz described the potential benefits of their low-cost battery in a Fox Business [newscast](http://video.foxbusiness.com/v/3053589553001/prototype-battery-may-be-cheap-renewable-energy-solution/#sp=show-clips).
