Long-distance hydrogen pipeline transportation
Thread Content
For long-distance hydrogen pipeline transportation, is it better to use a tunneling method or a bridging method?
Personally, I think it’s easier to repair something that spans across, while it’s harder to repair something that goes through
I have been researching information on hydrogen recently, and I found that it is extremely dangerous. Firstly, its molecules are small, and its flame is a pale blue color that makes it difficult to detect. The explosion limit is 4–75%, while its ignition energy is only 0.000019 J; thus, even a tiny spark can trigger an explosion. The safe flow rate is 8 m/s. Hydrogen is too dangerous.
