More developments in the field of ultracapacitors, this time using graphene (like a single layer of the graphite molecule, apparently), from researchers at the University of Texas:
“Through such a device, electrical charge can be rapidly stored on the graphene sheets, and released from them as well for the delivery of electrical current and, thus, electrical power,” says Rod Ruoff, a mechanical engineering professor and a physical chemist. “There are reasons to think that the ability to store electrical charge can be about double that of current commercially used materials. We are working to see if that prediction will be borne out in the laboratory.”
My understanding is that a key part of solving the two problems of anthropogenic climate change and the depletion of primary energy resources involves finding new and more efficient ways of storing energy.
Ultracapacitors are on option, synthetic petrol is another, or hydrogen fuel cells.
It will be interesting to see which technology (if any of these) becomes dominant as a means of storing energy.
