SAE International Rolls Out New Protocol for Hydrogen Fuel Cell EVs

SAE International has created a new standard, J2601 – Fueling Protocols for Light Duty Gaseous Hydrogen Surface Vehicles – that will be used worldwide for hydrogen fueling stations.

The standard is a light-duty hydrogen fueling protocol that will serve as the baseline for fueling the first-generation hydrogen fuel cell electric vehicles (FCEVs) with hydrogen.

‘SAE J2601 enables a safe and quick hydrogen fueling experience for FCEVs,’ according to Jesse Schneider, lead of the SAE J2601 and J2799 standards.

He explains that the standard gives hydrogen stations a fueling time of three to five minutes and that with a hydrogen fuel transfer equivalence of 100 to 200 kWh of electrical energy, the standard ‘establishes FCEVs as the only zero-emission vehicle technology to meet the same customer fueling and range expectations as conventional vehicles today.’

The standard J2601 fueling protocol uses a look-up table approach and an average pressure ramp rate, which has been verified over the last 13 years, the association says.

The SAE J2601 standard fueling tables use a simple control where the dispenser fuels until it reaches the target pressure – based on initial start conditions – giving a consistent hydrogen fueling, SAE International explains.
