High-level hazard analysis for pink hydrogen production

Pink hydrogen produced using nuclear-powered electrolysis emerges as a promising zero-emission solution. However, integrating high-temperature processes and nuclear-derived electricity for pink hydrogen production poses inherent safety risks. Hydrogen presents specific challenges due to its unique properties, including high flammability, wide explosion limits, and rapid diffusion. When coupled with nuclear power systems, these challenges are amplified, as the interaction between two inherently high-risk systems introduces new hazards and complexities. Furthermore, pink hydrogen is relatively new to industry and requires comprehensive safety protocols for its safe operation and production. This research conducts a detailed high-level hazard analysis to identify, assess, and control potential risks related to pink hydrogen production. Data and information were gathered through extensive research and team discussions. Various scenarios and consequences were assessed to ensure safe operation and plant performance. Initially, 26 high-risk scenarios were identified. Following implementation of mitigation measures, the number of high-risk scenarios was reduced to 2, demonstrating the effectiveness of the proposed controls. Implementing these recommendations and design modifications will help manage overall plant risk to a tolerable level. By addressing safety concerns proactively, this analysis contributes to the safe development and advancement of pink hydrogen technology for a sustainable future.
