en.Wedoany.com Reported - On June 26, the Hydrogen Energy Storage and Transportation Technology Exchange Meeting of China Oil & Gas Pipeline Network Corporation (PipeChina) was held in Beijing. The meeting officially released the hydrogen pipeline transportation engineering technical solutions and comprehensive standards, establishing a complete technical specification and standard system for the access, storage, transportation, and delivery of hydrogen pipelines. This fills the gap in China's long-distance, large-scale hydrogen pipeline transportation complete technology and standards, marking a key leap from single-point technological breakthroughs to systematic application for China's long-distance hydrogen pipelines.
The complete hydrogen pipeline transportation engineering technology released at the meeting closely addresses core engineering needs such as new hydrogen pipeline construction, natural gas pipeline hydrogen blending assessment and retrofitting, hydrogen access and delivery, operation management, maintenance, safety management, and integrity management. For the first time, it constructs a hydrogen pipeline transportation engineering technology roadmap, applicable to six sub-scenarios under two main application scenarios: new hydrogen pipeline construction and in-service natural gas pipeline conversion to hydrogen transport/hydrogen blending transport. The concurrently released standard system and comprehensive enterprise standards fully cover all key processes of hydrogen pipelines, including materials, design, construction, safety, and operation and maintenance, providing authoritative technical basis and standard support for pilot demonstrations and large-scale promotion of hydrogen pipeline transportation projects.
As a key link in the "production, storage, transportation, and utilization" of hydrogen energy, pipeline transportation is the core pathway for achieving large-scale, long-distance, and highly reliable hydrogen transport. It is also an important component of the new energy "quality-energy network" construction, playing a fundamental supporting role in improving the new energy system and promoting the large-scale implementation of the hydrogen energy industry.
Leveraging the resource advantages of the "National One Network," PipeChina continues to advance hydrogen pipeline transportation technology research and industrial layout. It has now formed a comprehensive capability integrating core technologies, standard systems, and testing platforms: overcoming the hydrogen embrittlement challenge in high-pressure pure hydrogen transport, developing China's first 10 MPa X60 steel grade dedicated hydrogen transport pipe; building the most functionally complete and highest pressure level 10 MPa pipeline hydrogen blending transport testing platform in China, clarifying the safe hydrogen blending boundary for in-service pipelines; independently developing core equipment such as leak monitoring systems; and constructing a four-tier linkage standard system covering enterprise, industry, national, and international levels, with multiple ISO international standards initiated.
The release of this complete hydrogen pipeline transportation engineering technology and standard system will effectively break through the technical barriers and standard bottlenecks hindering the large-scale development of hydrogen pipeline transportation in China. It will strongly support the industrialization and large-scale development of China's hydrogen energy industry, accelerate the layout of the new energy "quality-energy network," serve the "dual carbon" strategy and the construction of a new energy system, and continuously inject green "hydrogen" power into the construction of an energy powerhouse.
