Risks Associated with the Use of Hydrogen as an Energy Carrier or Source

Hydrogen is a dangerous gas due to its low ignition energy, wide flammability range, promotion of the embrittlement steel, and high coefficient permeation for polymers. The fracture toughness failure elongation pipe steels are strongly impacted by hydrogen embrittlement, whereas yield stress ultimate strength moderately impacted. Specific tools required defect assessment used transport hydrogen, which pure or blended with natural gas. safety factors associated cracks scratches obtained through diagram notch diagram. corrosion defects assessed limit analysis, estimated repair factor dents evaluated computing damage value under service pressure. design in calculation maximum admissible operating pressure (MAOP) modified depending on location pipes account lethal risks from torch effect explosion. It crucial monitor leaks domestic distribution networks, particularly closed areas.
