摘要
安全经济的氢气储运技术是氢能利用推向实用化、产业化的关键,35～75MPa高压储氢是现阶段可以商用的一种储氢方式。金属材料长期在常温高压氢环境中使用,可能出现氢脆现象,进而引发脆性破坏事故。该文以国内外的研究成果为基础,介绍常温高压氢脆机理,着重分析几种金属的抗氢脆性能,并提出若干关于我国压力容器常用金属抗氢脆性能研究的建议。
The safe and economical hydrogen storage technology is the linchpin of boosting the practicality and industrialization of hydrogen energy utilization. The high-pressure hydrogen storage at 35 - 70MPa is an available method for commercialization at present. Hydrogen embrittlement of metallic materials may occur after long-term serving in high-pressure hydrogen at ambient temperature, and cause brittle broken accident. In order to insure the long-term safe and reliable operation of high-pressure hydrogen storage system, hydrogen embrittlement of metallic materials in high-pressure hydrogen at nonnal temperature should be taken into account. The mechanism of hydrogen embrittlement in high-pressure hydrogen at normal temperature was introduced, the hydrogen compatibility of several materials was analyzed, the hydrogen compatibility of several materials was analyzed, and useful suggestions for the hydrogen compatibility research of pressure vessel materials were put forward in the paper.
