Cambridge Nano Systems Graphene production

All the companies moves to fast track high grade graphite production has been a good news story and a good off take agreement is sure to come soon. Only cautionary note seems to be around the potential for graphite to be used for graphene production. Cambridge NanoSystems spun out of The University, has a patent on producing impurity free Graphene from Methane. A 5 ton p/a pilot plant is about to begin. One would only want to count on the increased demand for graphite for battery production I would suggest?
