Engineering Assessment Process for Hydrogen Blending in Natural Gas Transmission

TC Energy is committed to "zero is real" in every facet of our business. Information sharing and industry networking related to safety is a critical strategy in achieving our goals as we begin our journey in the hydrogen development space.

Summary and Purpose:

This presentation will review TC Energy's framework for pursuing a pilot project that blends Hydrogen into an existing natural gas transmission lateral. This will be an interactive session providing a suggested framework for other member organizations to consider and to obtain feedback on how TC Energy can optimize the framework moving forward.

Content and Description:

1) Pilot goals and desired outcomes - this section will provide insight into why TC Energy is pursuing a blend pilot and what we hope to achieve from the pilot

2) Lateral screening and prioritization - this section will provide insight into how laterals were prioritized to determine top candidates for H2 blending pilot including variables analyzed

3) System overview - this section will provide a high-level overview of the system that TC Energy is considering including blending scope and interconnect considerations

4) High level risk screening - this section will provide an overview into TC Energy's risk assessment process including top risks and bow-tie diagram results

5) Regulatory framework - this section will provide insight into TC Energy's interpretation of the regulatory framework which governs this conversion including compliance planning

6) Engineering assessments (EA) - this section will provide insight into the EA framework that TC Energy has adopted to identify and evaluate the hazards that may result from the service change including proposed action items

7) Closeout plan and next steps - this section will provide guidance related to next steps required to deliver the project including engineering deliverables, operational readiness planning, public engagement and operational readiness.
