New Nanotech Batteries Might Get Wind and Solar on the Grid

October 31st, 2012 | by Charles Q. Choi

Solar and wind power both promise clean, renewable energy to the world, but there is currently no good way to deliver the electricity these alternative sources produce to potential customers. But scientists are developing novel batteries based on nanotechnology that can save solar and wind power energy and provide it on demand safely, quickly and inexpensively.

Fossil fuels like oil, coal and natural gas generate two-thirds of the world’s electricity right now. Concerns over their limited supplies and how they exacerbate global warming have spurred interest in greener, renewable sources of energy, such as solar and wind power.

Unfortunately, the sun and the wind are erratic sources of power. Solar power is only generated in the daytime and diminishes with cloud cover, while wind power fluctuates from moment to moment. For example, in Tehachapi, Calif., the wind can generate a few billion watts of power at some moments and only a few million watts or even nothing at others, and peak power production is typically at night when customer demand is low.
