The existing infrastructure was originally built for town gas which is ~50% hydrogen, and run successfully for many decades as such. So this is mainly about checking out the more recently designed parts. My understanding is embrittlement is mainly a problem for storage tanks, which need to use high strength materials due to the enormous pressure -and ironically those materials are more susceptable.
- alvah 2y agoExisting infrastructure is designed for & can be used for hydrocarbons with varying levels of hydrogen in their molecular structure; I don't believe there's an issue there. Most of the H2 in town gas is in the form of hydrocarbons, which are less reactive than pure H2, even if there's a relatively high percentage of H2 in the mix (as the H2 is strongly bound to the carbon). Embrittlement is definitely an issue for more than just storage tanks.
