Aim / Background

This course will introduce hydrogen in the context of the energy transition. It will offer a broad overview of the history of hydrogen and its pivotal role in the need for decarbonisation, including the different production methods and uses of hydrogen. Specifically, the need for hydrogen pipelines, and the differences between hydrogen and natural gas pipelines, will be covered. These differences are driven by the different characteristics of hydrogen and natural gas, including the embrittling effects of gaseous hydrogen. The operational and risk consequence aspects of hydrogen compared to natural gas will be compared and available code guidance on the conversion of natural gas pipelines will be summarised. The theory of hydrogen embrittlement and its associated cracking threats and effects on mechanical properties will be covered, as well as the relevant testing requirements and protocols. Finally, the impact of these differences on defect assessments and fitness for purpose studies will be introduced, and the requirements for a holistic hydrogen conversion and integrity management process outlined.

 

Agenda

1. Role of hydrogen in the energy transition:

  • History of hydrogen
  • Properties of hydrogen
  • Production of hydrogen (different colours)
  • Hydrogen demand and use
  • Requirement for hydrogen pipelines


2. Differences between hydrogen and natural gas pipelines:

  • Code requirements (ASME B31.12, AIGA / EIGA Guidelines, TD1 Supplement, DVGW G409 etc.)
  • Operational requirements (pressure, flow rates etc.)
  • Risk consequences (hazardous radius, likelihood of explosion etc.) 


3. Conversion of existing natural gas pipelines to hydrogen:

  • Code guidance
  • Operational requirements
  • Repurposing methodology

 

4. Effects of hydrogen on pipeline materials:

  • Theory of hydrogen embrittlement
  • Possibility of cracking (HIC)
  • Effects on strength, ductility, fracture toughness, fatigue
  • Implications for welds (seam and girth)
  • Testing requirements / protocols


5. Defect assessment:

  • Common defect types (crack-like defects, corrosion, dents, dent-gouges etc.)
  • Data requirements to assess defects
  • Assessment techniques (BS 7910, API 579 etc.) and hydrogen knock-down factors


6. Integrity management of hydrogen pipelines:

  • Requirements for an Integrity Management System for a hydrogen pipeline
  • Comparison to IMS for a Natural Gas Pipeline

 

Pre-School (optional)

Before your training on the ‘Fundamentals of Hydrogen’ with Neil Gallon begins, ROSEN's Competence Club, the premier learning and collaboration platform for the pipeline industry, is available for your use at no additional cost. This platform provides four complimentary pre-seminar e-learns that are designed to support you in acquiring the prerequisite knowledge for the course and enhancing your awareness level skillset. The e-learn training lasts a total of 8 hours and can be completed at your own pace and at a time that is convenient for you. The Competence Club training will cover: 

  • Introduction to Pipeline Materials CS013A (1 hour): Gain awareness of pipeline materials properties and selection and the composition and mechanical properties of carbon steel and corrosion-resistant pipeline materials, welds, connectors, flexible pipelines, and non-metallic pipeline materials. Learn more. 
  • Introduction to External Corrosion and Prevention CS017A (1 hour): This course provides an awareness of external corrosion and related degradation mechanisms on pipelines, of environmental effects, and of relevant mitigation strategies, factory-applied pipeline coating types, and field-applied coating types, including the key reasons behind the use of coatings, and an awareness of the requirements for the success of a coating over the lifecycle of an asset. Learn more.
  • Introduction to Crack Management CS050A (2 hours): Gain awareness of the different types of cracks and crack-like defects that can occur in pipelines, their effects and consequences, and how they are detected and mitigated. Learn more.
  • Introduction to Hydrogen Energy Transition and the Role of Pipelines CS053A (4 hours): This course outlines the minimum necessary principles, concepts, practices, problems, challenges, and technical parameters involved in the role of these transmission pipelines in the energy transition as well as technical, design, operation, and integrity management issues. Learn more.

Plus, as a referral member of ptc, you will have the chance to pick a complimentary e-learn course of your liking when you access your pre-school training through the Competence Club.

Target Group
If you're an engineer, a regulator, inspector, integrity consultant, or compliance officer looking to expand your knowledge of emerging fuels at a foundational level, this course is perfect for you. Additionally, as a cohort member, you'll have access to ROSEN's Competence Club, which provides awareness-level e-learns to prepare you for the session.
