Over the past decade, the State of California has supported the development of retail hydrogen refueling stations for light-duty (LD) fuel cell electric vehicles (FCEV) using grant funding, low carbon fuel standard (LCFS) credits, and direct assistance with station testing to incentivize private investments in the fueling network. The California Air Resources Board (CARB) utilizes a mobile test device, called the Hydrogen Station Equipment Performance (HyStEP) device, to test new light-duty hydrogen refueling stations before they are opened for public use. Testing is based on the CSA Group/ANSI Hydrogen Gas Vehicles (HGV 4.3), which evaluates station conformance to SAE J2601, the industry standard hydrogen fueling protocols.
The objective of this study was to assess in-use conformance of California’s existing light-duty hydrogen refueling stations with SAE J2601. SAE J2601 is the industry standard light-duty FCEV fueling protocol in the United States. The existing station population ranges in operating age from about 10 years since opening to recently opened. This study assesses conformance as a function of operational age. A representative sample of stations were tested using the testing device and an abbreviated version of the HGV 4.3 test method. HGV 4.3 is the test method used to verify stations conformance with SAE J2601 requirements.
