Organic mega-flow batteries, inspired by rhubarbs

There are a number of grid energy storage methods, including flow batteries, which have the potential to be scaled up with increased tank sizes, but that would be expensive due to the cost of metals involved in the process. Enter a research team from Harvard's School of Engineering and Applied Sciences, who have developed an organic mega-flow battery that utilize quinones, similar to those found in rhubarbs. The quinones serve as charge-carriers in chlorophyll during photosynthesis, with minimal degradation during the process, which is ideal for batteries used in large-scale energy storage and distribution. Some day, energy may be stored in "rhubarb batteries." (Abstract on Nature, paywalled article).
