A method for manufacturing a polymeric inner liner for a storage tank, in particular for a hydrogen storage tank, wherein the method comprises the steps of providing a cylindrical body made from polymer material and having a first open end; providing a dome-shaped end cap made from polymer material, the end cap having a base with a cross-section essentially corresponding to a cross-section of the first open end of the cylindrical body; placing the end cap with its base onto the first open end of the cylindrical body; and welding the end cap onto the first open end of the cylindrical body. The invention further concerns a polymeric inner liner manufactured according to such a method.
