SAE J2602 (Hydrogen Fueling Protocols)

SAE J2602 is a standard that defines how hydrogen fueling stations and fuel cell vehicles communicate during refueling. It ensures safe, efficient, and consistent operations by establishing protocols for connecting, verifying, and fueling hydrogen vehicles. This includes safety checks, pressure regulation, and timing to prevent leaks and over-pressurization. Essentially, SAE J2602 creates a common set of rules so hydrogen stations and vehicles can work seamlessly together, supporting reliable and safe hydrogen refueling infrastructure as hydrogen becomes a viable alternative fuel.
