Samband mellan skyddsnivå och risknivå för en vätgastankstation baserat på kvantitativ riskanalys

Sammanfattning: Currently, there are no given directives and regulations on how hydrogen refueling stations should be designed in Sweden. A proposal regarding hydrogen refueling stations H2-TSA, is being developed by Energigas Sverige and is expected to be published in 2023. The aim of this thesis is to contribute to development and future revisions of H2-TSA. It is done by analyze how a general hydrogen refueling stations is affected by adding or removing safety systems. Scenarios are based on the FMEA method and an overall description of the system. The results are based on a QRA and consequence simulations calculated in HyRAM+. Risks are quantified for each scenario and are then compared by relative risks. The conclusion indicates that the quantity of partition has a great impact on the level of risk. An increased variety of walls lowered the risk and a decreased variety of walls resulted in a major risk.
