| Station Design and Risk Assessment | 15% | Whether the station has a documented design basis covering hydrogen release, fire, explosion, overpressure, vehicle impact, emergency shutdown, and loss of power. | The design should be risk-assessed and engineered in accordance with the applicable edition of ISO 19880-1, together with locally adopted fire, pressure-equipment, electrical, and building requirements. | Design-basis document, hazard identification study, hazard and operability review, layout drawings, equipment list, and independent engineering review. | Required |
| Hydrogen Fuel Quality | 10% | Hydrogen purity, moisture, contaminants, sampling method, and quality-control records for fuel-cell vehicles. | Fuel should meet the applicable vehicle-fuel specification in ISO 14687. Sampling and laboratory results should be traceable to the delivered hydrogen batches. | Recent laboratory certificates, sampling procedure, certificate of analysis, supplier quality agreement, and nonconformance records. | Required |
| Vehicle Dispensing Protocol | 10% | Compatibility with the intended vehicle class, nominal dispensing pressure, communication, pre-cooling, fill control, and interruption handling. | For light-duty vehicles, the dispensing process should be compatible with SAE J2601. Common vehicle pressure classes are 35 MPa and 70 MPa; the selected station must match the fleet requirement. | Dispenser specification, protocol documentation, vehicle compatibility matrix, commissioning records, and representative fill-test results. | Required |
| Pressure Equipment and Storage | 10% | Storage vessels, compressors, valves, piping, pressure relief devices, inspection intervals, and protection against overpressure or mechanical damage. | All pressure-containing equipment should have traceable ratings, conformity documentation, inspection records, and relief-device discharge arrangements accepted by the relevant authority. | Pressure-vessel certificates, material certificates, relief-valve certificates, inspection plan, test records, and maintenance history. | Required |
| Codes, Standards, and Certification | 10% | Use of recognized hydrogen-station, hydrogen-equipment, electrical, fire-protection, and functional-safety standards. | The compliance matrix should identify the applicable requirements from ISO 19880-1, NFPA 2 where adopted, IEC 60079 for hazardous areas where applicable, and relevant local codes. | Signed compliance matrix, certificates of conformity, hazardous-area classification drawings, electrical inspection reports, and deviations register. | Required |
| Permits and Authority Approvals | 15% | Planning approval, building permit, fire authority approval, environmental review, hazardous-material authorization, pressure-equipment approval, and operating license. | Every permit required by the station’s jurisdiction should be identified, obtained, and valid before commercial operation. Permit requirements vary by country, state, province, and municipality. | Permit register, approved site plan, fire-authority letter, environmental documents, inspection sign-offs, occupancy approval, and operating permit. | Required |
| Emergency Response and Site Controls | 10% | Emergency-stop devices, gas and flame detection, ventilation, signage, restricted areas, vehicle-impact protection, evacuation routes, and responder access. | Controls should be documented, tested, clearly marked, and coordinated with local emergency services. Emergency procedures should cover leaks, fire, vehicle collision, power loss, and abnormal pressure. | Emergency response plan, detector calibration records, emergency-stop test reports, training records, site inspection checklist, and fire-service briefing record. | Required |
| Operational Availability | 10% | Actual station availability, planned maintenance, unplanned downtime, restart performance, spare-parts support, and remote monitoring. | Use at least 6–12 months of operating data where available. Set a contractual availability target appropriate to the fleet and define whether planned maintenance, upstream supply interruptions, and force majeure are excluded. | Monthly uptime reports, alarm history, maintenance logs, service-level agreement, downtime categorization, and spare-parts inventory plan. | Preferred |
| Refueling Performance | 5% | Successful fill rate, average transaction time, queue duration, pressure stability, temperature control, and frequency of aborted fills. | Require site acceptance tests using the intended vehicle type and operating conditions. Track successful transactions and aborted fills separately rather than relying only on rated dispenser capacity. | Commissioning test results, transaction database, dispenser event logs, temperature and pressure records, and customer-service reports. | Preferred |
| Cybersecurity and Control-System Resilience | 5% | Network segmentation, access control, secure remote maintenance, backup and recovery, software-update governance, and incident response. | Operational technology should be separated from public or corporate networks, privileged access should be controlled, and recovery procedures should be tested. Use an applicable industrial cybersecurity framework such as IEC 62443. | Cybersecurity architecture, access-control policy, vulnerability-management records, backup test results, incident-response plan, and supplier support procedure. | Verify |
