Could ultracaps be our energy-storage saviour?
Clean Break — ... from Elon Musk, co-founder and CEO of Tesla Motors, who before becoming an entrepreneur had plans to enroll in engineering graduate studies and focus on ultracapacitors for vehicles. I also mention some interesting work on ultracapacitor materials being done at Queen’s University in Kingston, and talk about a new ultracapacitor bus operating in Shanghai that will be demonstrated Wednesday in Washington, D.C. (for another more detailed article on the ultracap bus check out this Technology Review article). ...

Buses Using Ultracapacitors Will Be Put To The Test in Washington
Yale Environment 360 — A U.S. company and its Chinese partner will test electric buses using ultracapacitors that would be chargeable at stops every few miles. The latest ultracapacitors store only 5 percent of the energy that lithium-ion batteries can hold, making them impractical for passenger vehicles. But proponents say the fact that buses have to stop frequently — and at predictable locations — make them a more logical use of the technology. Virginia-based Sinautec Automobile Technologies and Shanghai Aowei Technology Development Company, a partnership that has run 17 ...

Tapping into Ultracapacitor Power for City Buses
GoodCleanTech — ... and Chinese partner Shanghai Aowei Technology Development Company have been testing the possibility of using ultracapacitors for city buses. Ultracapacitor technology is being considered as one of the alternative types of energy to power future inner-city buses. The problem with it is that ultracapacitors can only store about five percent of what energy lithium-ion batteries can. At the same time though, ultracapacitors can charge and discharge rapidly, making it possible for city buses inclined to stop every few blocks at bus stops to utilize the technology. In ...
