Food waste could store solar and wind energy, or there’s the obvious…
Saving up excess solar and wind energy for times when the sun is down or the air is still requires a storage device. Batteries get the most attention as a promising solution although pumped hydroelectric storage is currently used most often. Now researchers are advancing another potential approach using sugar alcohols—an abundant waste product of the food industry—mixed with carbon nanotubes.
