  • Electric mobility: Opportunities for climate protection in Europe

    Getting more electric vehicles on the roads in Europe can significantly reduce CO2 emissions and air pollutants within the European Union. If the share of electric mobility in passenger road transport increases to 80 percent by 2050, the CO2 emissions of the passenger road transport sector in Europe can be reduced by up to 84 percent compared to 2010.

  • Energy hybrid: Battery meets super capacitor

    Researcher at TU Graz demonstrates in Nature Materials that it is possible to combine the high-energy density of batteries with the high-power output of super capacitors in a single system – thanks to liquid energy storage materials. Batteries and super capacitors are electrochemical energy storage media, but they are as different as night and day. Both are capable of energy storage and targeted energy release – and yet there are major differences between the two. Batteries store very large amounts of energy that is released slowly but constantly. By contrast, super capacitors can only store small amounts of energy, but they release this energy much faster and more powerfully with large short-term peak currents.
