Proceeding 27256 Register

Application status: completed

Decision report issued: June 30, 2022


The AUC has recently concluded an inquiry on matters relating to hydrogen in natural gas distribution systems.

On November 5, 2021, the government of Alberta announced the Hydrogen Roadmap identifying the province as being well-positioned to participate in the evolving global hydrogen economy. The Hydrogen Roadmap recognized that the adoption of clean hydrogen has the potential to significantly reduce greenhouse gas emissions by 2030, with the province enabling hydrogen blending into natural gas distribution systems as a method to reduce greenhouse gas emissions.

On March 23, 2022, the government of Alberta issued an Order in Council directing the AUC to inquire into and report to the Minister of Energy on matters relating to hydrogen blending into natural gas distribution systems. On June 30, 2022, the AUC provided its report to the Minister of Energy which will be released publicly in the coming weeks.

The scope of the inquiry included the AUC gathering information, and making findings or providing observations or considering options on:

  • The role of regulated natural gas distribution systems and unregulated competitive markets for hydrogen blending into natural gas distribution systems up to 20 per cent blending by volume.
  • The impacts of blended hydrogen into low-pressure natural gas distribution systems, including:
    • Impacts on the delivery of services to municipal and rural natural gas consumers.
    • Competitive retail impacts.
    • Potential rate impacts.
    • Impacts on utility cost recovery for hydrogen blending, with reference to Section 37 of the Gas Utilities Act and any other relevant legislation, including the Public Utilities Act.
  • The safe and reliable delivery of blended hydrogen through natural gas distribution systems, including potential harmonization with municipal or other relevant safety standards.
  • Addressing regulatory ambiguity, removing unnecessary regulatory barriers, and improving certainty as required to enable hydrogen blending into natural gas distribution systems.
  • Areas for future study relating to hydrogen blending into natural gas distribution systems.


The AUC allowed parties the opportunity to reply to other parties’ submissions under the following schedule:
