Hydrogen and CO2 Pipeline Integrity Management

Day 1: (09:00 - 16:30)

Energy Transition

• Introduction to the Energy Transition
• History of hydrogen
• Properties of hydrogen
• Production of hydrogen (different colours)
• Hydrogen demand and use
• CO2 history, current dynamic and projects / landscape of CO2 pipelines
• Properties of CO2 and impact of impurities (to be also rediscussed in ops)

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

Differences Between Future Fuel and Natural Gas Pipelines

• Code requirements (AS2885 (H2 CoP), ASME B31.12, AIGA / EIGA Guidelines, TD1 Supplement, DVGW G409, DNV etc.)
• Operational requirements (pressure, flow rates etc.)
• Risk consequences (hazardous radius, likelihood of explosion etc.)
• Conversion of existing natural gas pipelines
• Code guidance
• Operational requirements
• Repurposing methodology

Networking Session 17:00-18:00 – Drinks and canapes provided.

Day 2: (09:00 - 16:30)

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.
• Running fracture in CO2 pipelines

Integrity management of hydrogen pipelines

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

Integrity management of CO2 pipelines

• Requirements for an Integrity Management System (IMS) for a CO2 pipeline
• Comparison to IMS for a Natural Gas Pipeline

Integrity Management of Future Fuels Pipelines

• Characteristic and threats associated with future fuels pipelines: Ammonia, LOHC, biogases
