Graphene offers enormous promise for energy storage, which is a critical need for making renewable energy more viable.

Graphene has two potential applications in energy storage:

  • As a supercapacitor,W storing energy directly[1]
  • Improving the capacity of existing battery technologies.[2]

These are relatively recent developments, and time to commercialization is uncertain.
