Hydrogen Safety
"Hydrogen safety concerns are not cause for alarm; They simply are different than those we are accustomed to with gasoline or natural gas" - Air Products and Chemicals Inc.
Several concerns for the fueling station would be addressed by adequate ventilation for the storage system, leak detection, and pressure relief valves for the high pressure storage.
Several modes of failure possible for the fueling station are: a pipe rupture, dispensing hose rupture, vehicle drive away while fueling, and nozzle leaks after the fueling process.
The fueling safety concerns would be addressed by implementing several control systems: one that would shut the system down and close all storage tank valves if a sudden pressure loss occurs, another for a break in connection during fueling, followed by hydrogen detection sensors that would sound alarms and close all system storage valves if the local concentration of hydrogen is above a specified air mixture level.
