Hemp based SC has been around for a while. 2013 rings a bell, Jumpstart added their research papers when we had the BB project,
My reading of the metal oxide decorated graphene, it has a much higher energy density to Hemp, the Hemp based SC have an energy density of 20wh/kg which is 20% of the capacity of Lithium-Ion batteries. with the MoDG having a similar capacity to lithium-ion,
