Graphene has been touted as the next wunderkind material for the better part of this millennium, due to its exceptional mechanical, electronic, and thermal properties. However, one look at the rocky history of carbon nanotubes shows that a research and patent boom along with impressive technical performance is far from a guarantee of commercial success, as major challenges like high costs, processing issues, and competing emerging material classes loom large. What’s more, a slew of recent capacity expansion announcements threaten to throw the space into oversupply. We assess the leading developers on the Lux Innovation Grid and forecast the future market potential across a range of applications. Our results reveal that the aggregate graphene market will grow to $126 million in 2020, with graphene nanoplatelets (GNPs) for composites and energy storage applications contributing the bulk of demand.
