New Carbon Material Sets Energy-Storage Record Likely To Advance Supercapacitors

Guided by machine learning, chemists at the Department of Energy’s Oak Ridge National Laboratory designed a record-setting carbonaceous supercapacitor material that stores four times more energy than the best commercial material. A supercapacitor made with the new material could store more energy — improving regenerative brakes, power electronics and auxiliary … [continued]

Solaris Sells 18 More Electric Buses To Cracow

Once again, European cities are outperforming American ones on the electrification of bus transit. I’ve talked about this before, but nothing has changed and they’re pulling even further ahead. Electric bus manufacturer Solaris recently sold another 18 articulated electric vehicles to public transport operator Miejskie Przedsiębiorstwo Komunikacyjne (MPK) in Cracow. … [continued]
