The advantages of Hydrogen are well known; what about the disadvantages? What are the storage challenges? What are the hydrogen embrittlement mechanisms and other damage mechanisms? 70–90% of the existing hydrogen pipelines are made of steel. It is crucial to understand the hydrogen damage mechanisms, their differences, and possible failure scenarios. This article identified and compared different damage mechanisms, evaluated real-world examples and failures, and analyzed the failures behind them. HEDE, HELP, AIDE, HIC, SSC, SCC, and HTHA all have different kinds of relations with steel. Good practices and, most importantly, correct material selection are lifesaving. After identifying the damage mechanisms, the article focused on the industry standards for best practices.
