The quantitative risk assessment of a hydrogen generation unit

Safety risk modeling and major accidents analysis of hydrogen and natural gas releases: A comprehensive risk analysis framework

“…Hydrogen is one of the most promising substance with many advantages that can be utilized in this sector [1]. Hydrogen is an environment-friendly fuel; the only matter that is produced when hydrogen is burned in an internal-combustion engine is harmless water vapor [2]. Hydrogen can be easily stored in different ways including highpressure cylinder, in the form of a cryogenic liquid fuel, hydrides, or on carbon fibers.…”

“…Hydrogen can be easily stored in different ways including highpressure cylinder, in the form of a cryogenic liquid fuel, hydrides, or on carbon fibers. As a raw material, moreover, hydrogen has many industrial applications such as the production of fertilizers, dyes, drugs, plastics, and so on [2,3].…”

“…In the last few years, there were several studies addressing various aspects of hydrogen safety with different objectives and methodologies that including: risk assessment/analysis on fueling stations [7e11], on distribution System [10], private car [12], and production facility [4]; consequence assessment/ analysis on fueling stations [13,14], and hydrogen applications [15]; QRA (Quantitative Risk Analysis) on fueling stations [16,17], and on generation unit [2]; risk/accident modeling on hydrogen station [18,19]. It can be clearly seen that the most studies are carried out on refueling stations, its transportation and other consumer facilities.…”

“…This is surely a good step, but researchers pay less attention to other sectors, especially on the production plants. Therefore, the risk studies of hydrogen activities cycle cannot be considered matured [2,4,20].…”

“…Furthermore, approximately 99% of hydrogen produced and consumed in industry is generated by natural gas reforming which increases the risks of fire and explosion [1,2].…”
