Addressing Challenges With Hydrogen Distribution, Pipeline Infrastructure, And Safety, Including Hydrogen Leakage And Overcoming The Constraints Of Existing Pipeline Repurposing Technology

08:45 Chair’s Opening Remarks

REPURPOSING NATURAL GAS PIPE INFRASTRUCTURE AS A COST-EFFECTIVE DISTRIBUTION SOLUTION

08:50 Technical Options For Cost Competitive Distribution Of Hydrogen Through Existing Natural Gas Pipelines

In North America, repurposing existing natural gas pipelines is viable and less expensive than starting from scratch. Overall, switching NG pipelines to hydrogen requires comprehensive and validated engineering research, therefore there is no "one size fits all" option. The technological processes required to reuse North America's pipeline infrastructure at a reasonable cost are outlined in the following case studies and research.

08:50 TECHNOLOGY FOR PIPELINE REPURPOSING Selection Of Technologies & Techniques For Transitioning Natural Gas Pipeline Infrastructure To Safely Blend Hydrogen In A Gaseous State
