If the car's own vapor recovery system is working properly, then the Stage II nozzle will only be vacuuming normal fresh air and depositing that into the gas station's underground fuel storage tanks. That ends up causing evaporation of fuel vapors into the atmosphere, because too much pressure builds up in those fuel storage tanks.
A hydrogen odorant in any form, is a minute amount of odorant such as ethyl isobutyrate, with a rotting-cabbage-like smell, that is added to the otherwise colorless and almost odorless hydrogen gas, so that leaks can be detected before a fire or explosion occurs. Odorants are considered non-toxic in the extremely low concentrations occurring in ...
