Researchers in the US have made a graphene-based supercapacitor that can store as much energy per unit mass as nickel metal hydride batteries – but unlike batteries, it can be charged or discharged in just minutes or even seconds. The new device has a specific energy density of 85.6 Wh/kg at room temperature and 136 Wh/kg at 80 °C.

Well it looks more promising than Hydrogen. Would be great to be able to offload cold-weather regen onto a supercap.
 
I see super-capacitors for just that in the first instance but eventually the way that we get a 200+mile EV that can be recharged in seconds at a refueling station.

They don't wear out.

If I were Obama, I'd have a task force on this right now, today - this is the 21st century Hoover Dam Project IMO.
