Pipeline infrastructure for hydrogen transport in the United States.

Integrated performance, economic, and life cycle emissions models show that hydrogen transport costs via dedicated and repurposed pipelines vary strongly by location, capacity, and distance across the United States.

• Why it matters: Existing pipeline models have underestimated construction-related material and labor costs versus U.S. historical data, limiting reliable planning for sustainable hydrogen transport infrastructure.
• What they did: The study builds integrated models to compare dedicated pipelines and repurposed natural gas pipelines nationwide, then applies multi-criteria analysis to evaluate cost and life cycle emissions tradeoffs.
• The result: The modeling framework and multi-criteria approach better guide engineering design, planning, and investment decisions for nationwide hydrogen transport networks, highlighting upfront savings versus potential cost and emissions tradeoffs.
