Abstract
The international standards about hydrogen fueling protocol are SAE J2799, ISO 19885 and ISO/TC 197 WG 24. SAE J2799 is the first international standard about hydrogen fueling protocol in the world and ISO 19885 and ISO/TC 197 WG 24 are the upgraded international standard of SAE J2799. Three standards are applied in the hydrogen fuel cell vehicle market, but unfortunately there is no criteria about safety of hydrogen fueling protocol. From near future, Korea government will permit the high speed hydrogen fueling for the competition with gasoline vehicle or diesel vehicle. The hydrogen tank in hydrogen fuel cell vehicle can be exploded when the temperature of hydrogen increase over the certain temperature during high speed fueling. More quantitative process hazard analysis is necessary to prevent this kind of explosion. So the HAZOP and LOPA are executed for process hazard analysis of hydrogen fueling protocol and the instrument design was developed by applying the result of HAZOP and LOPA. HAZOP is qualiitative analysis and LOPA is semi-quantitative analysis. For the efficient hazard and risk analysis, PHA Pro was used for HAZOP and LOPA report. Considering the normal criteria of HAZOP and LOPA, SIL3 needs to be applied to design the instrument system of hydrogen fueling protocol. The instrument system configuration and design criteria are modified and proposed as a the result of LOPA.
