Directory of theories and practical applications, as well as companies that are utilizing nanotechnology for improving energy generation techniques as well as deriving new energy modalities altogether.

Applications to Energy

Nanotechnology could turn out to be the most important technological development for advancing energy technolgies in well over one hundred years. Nanotechnology, which means building technology on the molecular or nano (billionths) scale, has already started to impact solar energy and battery storage technology. Nanotechnology might someday allow for far more powerful, more efficient and less expensive solar and battery storage technology. Nanotechnology is a rather young field, only gaining acceptance in the late 1990s, so the potential for future nanotechnology-based energy advancements is very high in coming years.

Overviews

  • Carbon Nanotubes and other Nanotechnology Solutions for Renewable Energy - From vastly increasing efficiencies in solar power to reducing costs of hydrogen generation, the alternative energy sector is seeing a range of nanotech developments.

Example of Nanotechnology Effecting Energy Technology

An example of how nanotechnology affects energy technology is recent announcements by battery companies that indicate that by using nanotechnology to design new anodes and cathode materials, they are able to greatly increase the amount and rate of energy that can be transferred to a battery, and reduce the recharge times significantly as a result.

Battery companies have also introduced nanotechnology battery designs that are capable of storing more energy than previous designs, by making better use of a battery's storage potential.

Solar engineers have reported early nanotechnology-based breakthroughs in solar technology that might: allow a far wider spectrum of solar energy to be captured by future solar cells, allow solar cells to be able to convert solar energy to electricity far more efficiently, allow solar collectors to be painted on just about any surface, and could bring down the cost of solar technology significantly.
