Was it Skeleton Technologies ?

FGR are currently in R&D with their own Graphene Supercapacitor. It currently exceeds Skeleton's results,

There is another company called Kilowatt labs, that seems to have better results, you can currently buy their SC in Melbourne as part of a battery storage unit. It has a expected life of 45 year. https://solarbatteriesonline.com.au...-day-kit-with-kilowatt-labs-super-capacitors/

Agree about the directions of energy storage, certain members of our government wants to bring back coal. WTF.
