摘要

Utilities would love to be able to store the power that wind farms generate at night and use it when demand is high during the day. But conventional battery technology is so expensive that it only makes economic sense to store a few minutes of electricity. Harvard University researchers say they've developed a new type of battery that could make it economical to store a couple of days' worth of electricity from wind farms and other sources. The new battery is based on an organic molecule-called a quinone-that's found in plants such as rhubarb and can be cheaply syn- thesized from crude oil. The molecules could reduce by two-thirds the cost of the materials in a type of battery called a flow battery, which is particularly well suited to storing large amounts of energy.
