RP3.2-12 Addressing hydrogen blending issues: gas mixing, demixing and hydrogen analysis

Executive Summary

This projects expand the knowledge and technology supporting the transport and delivery of hydrogen/natural gas blends by considering two physically linked processes: mixing and demixing. Research activities relevant to mixing aim to develop guidelines for best practice. Parallel research activities aim to clarify the possibility, conditions and impact of mechanisms leading to a decrease in homogeneity.

Commencement / End Date September 2022 to June 2024
Outcomes / Impact

Outcomes of the project will establish confidence in delivery of
hydrogen/natural gas blends. It will inform network operators of:

  • Where hydrogen should be injected in a network,
  • Where gas quality should be measured downstream of injection
  • Cost-effective methods for real-time monitoring of hydrogen
    content across the network,
  • Whether the likelihood and impact of demixing mechanisms
    warrant further considerations.
