As automakers ramp up their plans to put greener vehicles on the road, hydrogen storage has become a pivotal issue. Whereas it’s been suggested that graphene could play an important role in retaining hydrogen for use in fuel cells and other technologies, a team of researchers at the National Institute of Standards and Technology (NIST) and the University of Pennsylvania in Philadelphia say they’ve found a way to configure graphene that enables it to hold 100 times more hydrogen molecules than a single layer of the carbon-based substance.
