I wouldn't say that information is missing. Details of it are, but implications are it has cheaper lifecycle costs.
"By substituting current active ingredients such as zinc with lower quantities of higher performing non-toxic graphene alternatives, the application, environmental and maintenance costs of steel vessels and infrastructure can be reduced."

I would say significantly reduced lifestyle costs are implied."2 orders of magnitude decrease in corrosion rate over zinc-rich epoxy." Even if it were more expensive initially (although less is needed, and application costs can be reduced), it lasts 100x longer. This means cheaper from multiple standpoints. 100x less maintenance required, implies less man hrs, materials and time of product (ship/steel/etc) in unusable phase.
