  • Understand the specifics of transporting the dihydrogen (H2) molecule
  • Adapt network and measuring equipment for the integration of hydrogen into the gas grid
  • Determine the adaptations to implement with hydrogen’s integration to maintain the requirement level of the gas infrastructure
Major challenges
Scope
  • All actions related to the development of hydrogen, including “Power to Gas”
  • Determine the H2 impact on pipeline integrity and network equipment (durability, tightness)
  • Determine the H2 impact on the gas quality analyzers and metering equipment
  • Determine the H2 impact on maintenance, operations and inspection
  • Develop mitigation solutions and new materials/equipment
  • Strengthen knowledge about H2-related safety
  • Adapt network operating conditions, compression criteria and management system
Key drivers
Looking ahead to 2030
  • New FenHYx test benches dedicated to integrity and leak-tightness under hydrogen conditions will be commissioned in 2021: tensile testing machine, autoclave, aging modules…
  • Extension of the material testing program across the H2 concentration range (from 0 to 100%) and over the entire GRTgaz network
  • Development of new materials suitable for H2 transmission
  • Qualification of chromatographs in-situ
  • Adapt compressors to H2
  • Adapt the network inspection and operating procedures
  • Develop H2/CH4 separation solutions for sensitive uses
