Advances in Constructional Engineering

This paper conducts research on hydrogen pipeline transportation technology, focusing on its crucial role in the global energy low-carbon transition. First, elaborate on the type, principle and applicable scenarios of this technology. Then, analyze the development direction of the technology. Subsequently, point out the challenges in three aspects: technology, economy and standard norms, and propose targeted countermeasures such as full-chain technological breakthroughs, cost reduction and efficiency improvement, and the construction of a unified standard system. The article also takes the State Power Investment Corporation's Chaoyang hydrogen Blending Project as an example to verify the technical feasibility and value, hoping that this article will be helpful to relevant practitioners.
