Technical Information Report (TIR) Establishes Protocols for Fueling of Compressed Gaseous Hydrogen Vehicles at Peak Flow Rates

WARRENDALE, Pa. (Feb. 29, 2024) – SAE International recently issued a Technical Information Report (TIR) J2601/5_202402, “High-Flow Prescriptive Fueling Protocols for Gaseous Hydrogen Powered Medium and Heavy-Duty Vehicles.” The TIR establishes high-flow fueling protocols, including process limits for fueling of compressed gaseous hydrogen vehicles at peak flow rates from 60 to 300 g/s with compressed hydrogen storage system (CHSS) volume capacities between 248.6 and 7500 L which have been qualified to UN GTR #13.

Steve Mathison, VP of Hydrogen Technologies at FirstElement Fuel, Inc., and the document sponsor for TIR J2601/5 notes that, “The publication of TIR J2601/5 marks an important milestone in the quest to commercialize medium and heavy-duty fuel cell vehicles where quick refueling is paramount to their competitiveness against current diesel-powered vehicles.  The fueling protocols in TIR J2601/5 facilitate sub-10 minute fueling of trucks and buses with on-board hydrogen storage capacities of up to 120 kg, potentially providing up to 1000+ miles of driving range.  Because these fueling protocols are general purpose, they are appropriate for all vehicles and can be utilized at public and private access stations.”  FirstElement Fuel owns and operates a network of hydrogen stations in California.

The SAE Fuel Cell Standards Committee initially published the document as a TIR due to limited field testing of the fueling protocols. Once the fueling protocols have been field tested, the SAE Fuel Cell Standards Committee Interface Task Force intends to publish a revision to this document as an SAE Standard.

This document provides general-purpose fueling protocols which are appropriate for vehicles utilizing these high-flow fuel delivery components. Fuel delivery components (break-away, hose, nozzle, receptacle) capable of these flow rates are expected to soon be published in applicable standards and be available for use.
