Day 1

Role of hydrogen in the energy transition:

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

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.) 

Conversion of existing natural gas pipelines to hydrogen:

• Code guidance
• Operational requirements
• Repurposing methodology
