Since the first energy crisis in the early 1970s, in several “waves,” hydrogen was promoted as an emission-free energy carrier and as a potential surrogate for fossil fuels. Safety was always considered crucial, especially for the widespread decentralized use in the public domain. Untrained customers needed fail-safe technologies, easy to handle with obvious and convincing safety features. However, the hydrogen-safety knowledge from industry and space applications as well as from nuclear-safety research remained not only geographically and thematically fragmented but also partially applicable. As a result, achieving harmonized methodology and standardization were almost impossible under these circumstances.
