Renewable Energy's Problem: Storage; 

(Potential) Harvard's Solution: Quinones--Which are found in Rhubarb

SimplyRecipes: Rhubarb Pie

One of the major setbacks to renewable energy is insufficient energy storage. There is potentially a solution to this. It's called Quinones. And it is found in Rhubarb

This organic compound, Quinone,

• Chemical compound in Rhubarb
• Can hold energy (1KW hour of energy)
• Is naturally abundant
• Is Stable 
• Inexpensive--third of the price of existing systems.
• Water Soluble
• Is safer than metal-based batteries

Published Paper in Nature

BusinessInsider: A "group of organic compounds, called quinones, can be used to create an inexpensive battery capable of charging and discharging renewable electricity much more rapidly than existing metal batteries can.

The trick is that they are water soluble, which means you can set up large, inexpensive tanks to hold electricity, instead of having to engineer solid-state batteries like ones found in cars."
