Pipeline National Grid Releases Complete Technical Standard System for Hydrogen Transmission

On 2026, 7, 7, the PipeChina Group released its complete technical and standards framework for hydrogen pipeline transportation, marking a major breakthrough in China's long-distance, large-scale hydrogen pipeline transport technology.

I. Technical Breakthroughs

The National Pipeline Network Group has overcome the critical challenge of hydrogen embrittlement in high-pressure pure hydrogen transmission, successfully developed 10 MPa hydrogen-specific steel, and established China's highest-pressure blended hydrogen test platform.

II. Standard System

The published technical standard system covers the entire process from design, construction, and operation to safety, providing unified technical specifications for hydrogen pipeline engineering projects.

3. Two Technical Pathways

1. Build dedicated hydrogen pipelines: Ideal for large-scale green hydrogen export projects. 2. Retrofit natural gas grids with hydrogen blending: Leverage existing infrastructure to reduce capital costs.

IV. Industry Significance

This breakthrough addresses the long-standing challenge of low-cost cross-regional transport that has constrained industry development, providing technical assurance for large-scale wind and solar green hydrogen export projects and significantly reducing green hydrogen transportation costs.

Shanyao New Energy's planned green hydrogen projects in Inner Mongolia, Xinjiang, and other regions will benefit from this breakthrough, enabling future pipeline delivery of green hydrogen to eastern consumer markets.
