輸氫管道發(fā)展及氣相氫脆研究

主講人 : Prof. Frank Cheng

Hydrogen has become a critical player in energy transition. Hydrogen delivery is integral to the entire value chain of hydrogen economy. Of various modes for hydrogen distribution, pipelines provide an economical and effective means to transport hydrogen with an increased capacity over long distances. Pipeline steels are prone to hydrogen embrittlement (HE) in high-pressure hydrogen gas if hydrogen (H) atoms generate from the gaseous environment and enter the steels. The HE can compromise structural integrity and cause failures of the pipelines. The HE of hydrogen pipelines is unique. Major gaps exist in both fundamental and applied aspects. This talk will provide fundamentals of gaseous HE of steels, detailing specific features of the problem. A thermodynamic model is developed to evaluate the feasibility of H atom generation from high-pressure gaseous environments. The density functional theory is used to determine stable configurations for H atom adsorption and absorption on crystalline lattice plane, grain boundaries and dislocations. The mechanical properties of pipeline steels in high-pressure hydrogen gas environments are reviewed, and novel methods to detect H atoms in steels are intriduced.
