Abstract

It is proposed a plastic liner for the storage of hydrogen, comprising: a first barrier layer (3), a second barrier layer (7) configured to be an inner layer in contact with hydrogen, at least one intermediate layer arranged between the first and the second barrier layers, wherein the second barrier layer (7) has a lower hydrogen permeability than said at least intermediate layer such that the second barrier layer (7) slows down the migration of hydrogen inside said at least one intermediate layer.
