The presentation will dive deep into the practical realities and considerations of transitioning from a natural gas distribution grid to a 100% hydrogen grid. Through real-world experiment results, we'll address key concerns related to:

Leakage: While hydrogen leaks faster than natural gas, well-managed small leaks pose no greater risk. Permeation testing of polymers is crucial for assessing their suitability in high-pressure hydrogen environments.

Purging: Existing purging techniques can be effectively applied to remove residual gas before hydrogen introduction.

Safety: Venting and flaring can be carried out safely. Existing closing methods may require modifications for optimal safety with hydrogen. Hydrogen's wider flammability limits, lower ignition energy requirements, and larger potential explosion impact necessitate careful safety considerations.

By attending this presentation, the audience will explore the practical steps towards a safe hydrogen infrastructure, grounded in concrete testing data.
