Refuelling protocols

Refuelling protocols in hydrogen refuelling stations are used for safe and high-performance refuelling of everything from forklift trucks to heavy-duty trucks. By adhering to these protocols, manufacturers and operators of hydrogen vehicles can ensure a consistent and reliable refuelling experience for end users. Various international standards define specific requirements for the hydrogen refuelling process that relate to pressure and temperature parameters. In Europe, ISO EN 19880, which references SAE J 2601, applies to car refuelling. For truck refuelling at 350 bar, the industry-wide CEP technical standard is currently used. The next step in the further development of truck refuelling will be the implementation of SAE J2601-5 at filling stations.
