  The experimentally observed metal-to-insulator transition in hydrogenated
graphene is numerically confirmed for actual sized graphene samples and
realistic impurity concentrations. The eigenstates of our tight-binding model
with substitutional disorder corroborate the formation of electron-hole-puddles
with characteristic length scales comparable to the ones found in experiments.
The puddles cause charge inhomogeneities and tend to suppress Anderson
localization. Even though, monitoring the charge carrier quantum dynamics and
performing a finite-size scaling of the local density of states distribution,
we find strong evidence for the existence of localized states in graphene
nanoribbons with short-range but also correlated long-range disorder.
