Cathodic protection against corrosion is a well-known source of hydrogen but exposing the full internal surface of a pipeline to high pressure hydrogen gas is a situation not addressed by current national standard for pipeline systems. Thus, hydrogen transport represents a new situation for the regulatory authorities, operators, owners and users of the existing pipelines and producers of new pipelines. All these stakeholders are contributing to HyLINE.
The primary objective of HyLINE is therefore to build fundamental knowledge and competence to ensure safe and efficient use of existing and new pipeline infrastructure.
The main topics to be addressed are:
- How can H get into the material?
- How fast H gets into the material.
- How much H can the material take?
- What H does to the material when it has entered.
- How to predict effects of H throughout the lifetime of a pipe.
- How to mitigate these effects.
