This bright blue dye is found in fabric: Could it also power batteries?

Methylene blue is a common ingredient in wastewater from textile mills. But scientists think it may be possible to give this industrial pollutant a second life. In a study, they show that the dye, dissolved in water, is good at storing and releasing energy on cue. This makes the compound a promising material for redox flow batteries, which could store energy for wind farms and solar homes.
