BlendPATH v2.1

• Dedicated hydrogen pipeline modification method
  • Builds a dedicated pure hydrogen pipeline parallel to the natural gas pipeline in a new right of way
  • Transports the targeted blend amount of hydrogen, rather than same same energy content of the original pipeline
• Improve hydraulic model computation time to enable more complex networks
• Composition tracking and mixing for varying composition at supply nodes
• Compressor bypass
  • By default, allow compressor bypass is on
  • Allow DR and PL modification methods to bypass existing compressors if that option yields lower costs
  • Bypassed compressors do not incur any refurbishment, salvage, or decommissioning cost
